Phase-detection autofocus "sees" through window glasses without problems and is much more accurate, but it does not work in low-light conditions or on surfaces without contrasts or with repeating patterns. A very common example of combined usage is the phase-detection auto-focus system used in single-lens reflex cameras since the 1985s. The passive phase-detection auto-focus needs some contrast to work with, making it difficult to use in low-light scenarios or on even surfaces. An AF illuminator will illuminate the scene and project contrast patterns onto even surfaces, so that phase-detection auto-focus can work under these conditions as well. A newer form of a hybrid system is the combination of passive phase-detection auto-focus and passive contrast auto-focus, sometimes assisted by active methods, as both methods need some visible contrast to work with. Under their operational conditions, phase-detection auto-focusing is very fast, since the measurement method provides both information, the amount of offset and the direction, so that the focusing motor can move the lens right into (or close to) focus without additional measurements. Additional measurements on the fly, however, can improve accuracy or help keep track of moving objects. However, the accuracy of phase-detection auto-focus depends on its effective measurement basis. If the measurement basis is large, measurements are very accurate, but can only work with lenses with a large geometrical aperture (e.g. 1:2.8 or larger). Even with high contrasty objects, phase-detection AF cannot work at all with lenses slower than its effective measurement basis. In order to work with most lenses, the effective measurement basis is typically set to between 1:5.6 and 1:6.7, so that AF continues to work with slow lenses (at least for as long as they are not stopped down). This, however, reduces the intrinsical accuracy of the ------------------------------ Date: Sat, 7 Nov 2020 03:50:40 -0500 From: "VirtualPilot3D" Subject: Still hunting for holiday gifts?

If a focal-plane shutter camera is left with sunlight falling on the lens (and the mirror up for an SLR), it is possible to burn a hole in the closed curtain of a non-metal shutter. Camera shake due to the impact of the larger curtains starting and stopping rapidly. Camera designers have learned to overcome SLR mirror-slap by including a mirror lock-up feature in some cameras. This removes the camera-shake from the large slapping mirror inside the camera, but does not prevent camera-shake caused by the shutter mechanism itself. Mirror-lock-up introduces yet another problem: with the mirror locked-up out of the way the optical viewfinder cannot be used for focussing, framing, or exposure metering. Newer DSLR cameras include a "live preview" where the image from the main imaging sensor is displayed directly on an LCD display, so it is still possible to focus (manually or in newer models by contrast detection) and frame. This prevents most camera shake from the focal-plane shutter, as instead of a first curtain an electronic shutter is used. Simple leaf shutter Simple leaf shutter 1. Shutter plate 2. Aperture covered by leaf shutter 3. Aperture during exposure 4. Leaf blade 5. Catch mechanism 6. Butterfly spring A simple leaf shutter is a type of camera shutter consisting of a mechanism with one or more pivoting metal leaves which normally does not allow light through the lens onto the film, but which when triggered opens the shutter by moving the leaves to uncover the lens for the required time to make an exposure, then shuts. Simple leaf shutters have a single leaf, or two leaves, which pivot so as to allow light through to the lens when triggered. If two leaves are used they have curved edges to create a roughly circular aperture. They typically have only one shutter speed and are commonly found in basic cameras, including disposable cameras. Some have more than one speed. Shutters for newer digital cameras are a combination of electronic and mechanical timings. Some cameras employ a 100% electronic shutter, created by turning on and off the imaging sensor's signals. Digital cameras that can also take video implement this method for their video modes. For single-frame photography then either mechanical or mechanical and electronic methods are used. ------------------------------ Date: Sat, 7 Nov 2020 03:38:12 -0500 From: "Much Love From La Date" Subject: Singles are waiting and ready to mingle Singles are waiting and ready to mingle http://carterminator.buzz/1y6e0WpunZuBd4uB78LnuziL2kMOTtI-OcspX_0JBkK4v7wl http://carterminator.buzz/GtObnw2U5WJb5gmcfk6AbuseJjiVMxF6oMhYlXrKUaM48Wlg under heavy wear and tear. Each time a VHS cassette was played, the magnetic tape inside had to be yanked out and wrapped around the inclined drum head inside the player. While a VHS tape can be erased if it is exposed to a rapidly changing magnetic field of sufficient strength, DVDs and other optical discs are not affected by magnetic fields.[citation needed] The relative mechanical simplicity and durability of DVD compared to the fragility of VHS made DVDs a far better format from a rental store's perspective. Though DVDs do not have the problems of videocassettes, such as breakage of the tape or the cassette mechanism, they can still be damaged by scratches. Another advantage from the perspective of video rental stores is that DVDs are physically much smaller, so they take less space to store. DVDs also offer a number of advantages for the viewer; DVDs can support both standard 4x3 and widescreen 16x9 screen-aspect ratios, and can provide twice the video resolution of VHS. Skipping ahead to the end is much easier and faster with a DVD than with a VHS tape (which has to be rewound).[citation needed] DVDs can have interactive menus, multiple language tracks, audio commentaries, closed captioning, and subtitling (with the option of turning the subtitles on or off, or selecting subtitles in several languages). Moreover, a DVD can be played on a computer.[citation needed] Due to all these advantages, by the mid-2000s, DVDs had become the dominant form of prerecorded video movies in both the rental film and new movie markets.[citation needed] In the late 2000s, stores began selling Blu-ray discs, a format that supports high definition.[citation needed] Early 4K Blu-ray release at Best Buy: A 4K Blu-ray disc player was also released. Blu-ray is a digital optical disc data storage format, designed to supersede the DVD format, and is capable of storing several hours of video in high definition (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games. The plastic disc is the same size as DVDs and compact discs. Blu-ray was officially released on June 20, 2006, beginning the high-definition optical disc format war, in which Blu-ray Disc competed against the HD DVD format. Toshiba, the main company supporting HD DVD, conceded in February 2008. Blu-ray faces competition from video on demand (VOD) and the continued sale of DVDs. Notably, as of January 2016, 44% of U.S. broadband households had a Blu-ray player. In the late 1990s and early 2000s, though, consumers continued to use VCRs to record over-the-air TV shows, because consumers could not make home recordings onto DVDs.[citation needed] This last barrier to DVD dominance was broken in the late 2000s, with the advent of inexpensive DVD recorders and other digital video recorders (DVRs). DVR devices, which record shows onto a hard disk or flash storage, can be purchased from electronics stores or rented from cable or satellite TV providers.[citation needed] Despite the mainstream dominance of DVD, VHS continued to linger on into the 2000s and gradually faded into history during the 2010s. The switch to DVD initially led to the marketplace being flooded with used VHS videocassettes, which were available at pawnshops and second-hand stores, typically for a much lower price than the equivalent film on a ------------------------------ Date: Sat, 7 Nov 2020 05:07:37 -0500 From: "Great Gift" Subject: CLAIM Your Trump 2020 Commemorative Golf Ball CLAIM Your Trump 2020 Commemorative Golf Ball http://catspraying.buzz/ByRcI0WLlj9ak4iISX5DDmIIJ8am-h-WGJj_e1JfSu3jdEdx http://catspraying.buzz/JUnEiRhTdaTbmcdCKOiJwdIuy9AhSu-fk4MfI11Rvf9pEoli There are various ways to measure distance, including ultrasonic sound waves and infrared light. In the first case, sound waves are emitted from the camera, and by measuring the delay in their reflection, distance to the subject is calculated. Polaroid cameras including the Spectra and SX-70 were known for successfully applying this system. In the latter case, infrared light is usually used to triangulate the distance to the subject. Compact cameras including the Nikon 35TiQD and 28TiQD, the Canon AF35M, and the Contax T2 and T3, as well as early video cameras, used this system. A newer approach included in some consumer electronic devices, like mobile phones, is based on the time-of-flight principle, which involves shining a laser or LED light to the subject and calculating the distance based on the time it takes for the light to travel to the subject and back. This technique is sometimes called laser autofocus, and is present in many mobile phone models from several vendors. It is also present in industrial and medical devices. An exception to the two-step approach is the mechanical autofocus provided in some enlargers, which adjust the lens directly. Passive Passive AF systems determine correct focus by performing passive analysis of the image that is entering the optical system. They generally do not direct any energy, such as ultrasonic sound or infrared light waves, toward the subject. (However, an autofocus assist beam of usually infrared light is required when there is not enough light to take passive measurements.) Passive autofocusing can be achieved by phase detection or contrast measurement. Phase detection Phase detection: In each figure (not to scale), the area within the purple circle represents the object to be focused on, the red and green lines represent light rays passing through apertures at the opposite sides of the lens, the yellow rectangle represents sensor arrays (one for each aperture), and the graph represents the intensity profile as seen by each sensor array. Figures 1 to 4 represent conditions where the lens is focused (1) too near, (2) correctly, (3) too far and (4) much too far. The phase difference between the two profiles can be used to determine in which direction and how much to move the lens to achieve optimal focus. Phase detection (PD) is achieved by dividing the incoming light into pairs of images and comparing them. Through-the-lens secondary image registration (TTL SIR) passive phase detection is often used in film and digital SLR cameras. The system uses a beam splitter (implemented as a small semi-transparent area of the main reflex mirror, coupled with a small secondary mirror) to direct light to an AF sensor at the bottom of the camera. Two micro-lenses capture the light rays coming from the opposite sides of the lens and divert it to the AF sensor, creating a simple rangefinder with a base within the lens's diameter. The two images are then analysed for similar light intensity patterns (peaks and valleys) and the separation error is calculated in order to find whether the object is in front focus or back focus position. This gives the direction and an estimate of the required amount of ------------------------------ Date: Sat, 7 Nov 2020 02:40:44 -0500 From: "**Angela**" Subject: Opportunities trebled with the Trinity!

Focal-plane shutters are usually implemented as a pair of light-tight cloth, metal, or plastic curtains. For shutter speeds slower than a certain point (known as the X-sync speed of the shutter), which depends on the camera, one curtain of the shutter opens, and the other closes after the correct exposure time. At shutter speeds faster than the X-sync speed, the top curtain of the shutter travels across the focal plane, with the second curtain following behind, effectively moving a slit across the focal plane until each part of the film or sensor has been exposed for the correct time. The effective exposure time can be much shorter than for central shutters, at the cost of some distortion of fast-moving subjects. Focal plane shutters have the advantage over central leaf shutters of allowing the use of interchangeable lenses without requiring a separate shutter for each lens. (Leaf shutters behind the lens also allow interchanging the lens using a single shutter.) They have several disadvantages as well: Distortion of fast-moving subjects: although no part of the film is exposed for longer than the time set on the dial, one edge of the film is exposed an appreciable time after the other, so that a horizontally moving shutter will, for example, elongate or shorten the image of a car speeding in the same or the opposite direction to the shutter movement. They are noisier, which is a detriment to candid and nature photography. Their more complex mechanical structure causes a shorter life-span than other shutter designs. If a focal-plane shutter camera is left with sunlight falling on the lens (and the mirror up for an SLR), it is possible to burn a hole in the closed curtain of a non-metal shutter.

There appears to be short-term increases in attention span, verbal and visual memory in some studies. However, the effects are transient and diminishes over time and after cessation of the physical activity. Dietary supplements Studies evaluating phytoestrogen, blueberry supplementation and antioxidants showed minor increases in cognitive function after the supplementation compared to before but no significant effects compared to placebo. Pleasurable social stimulation Exposing individuals with cognitive impairment (i.e., Dementia) to daily activities designed to stimulate thinking and memory in a social setting, seems to improve cognition. Although study materials are small, and larger studies need to confirm the results, the effect of social cognitive stimulation seems to be larger than the effects of some drug treatments.

It is a state of arousal. William James (1890) wrote that " is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence." Attention has also been described as the allocation of limited cognitive processing resources. Attention is manifested by an attentional bottleneck, in term of the amount of data the brain can process each second; for example, in human vision, only less than 1% of the visual input data (at around one megabyte per second) can enter the bottleneck, leading to inattentional blindness. Attention remains a crucial area of investigation within education, psychology, neuroscience, cognitive neuroscience, and neuropsychology. Areas of active investigation involve determining the source of the sensory cues and signals that generate attention, the effects of these sensory cues and signals on the tuning properties of sensory neurons, and the relationship between attention and other behavioral and cognitive processes, which may include working memory and psychological vigilance. A relatively new body of research, which expands upon earlier research within psychopathology, is investigating the diagnostic symptoms associated with traumatic brain injury and its effects on attention. Attention also varies across cultures. The relationships between attention and consciousness are complex enough that they have warranted perennial philosophical exploration. Such exploration is both ancient and continually relevant, as it can have effects in fields ranging from mental health and the ------------------------------ Date: Thu, 5 Nov 2020 03:12:24 -0500 From: "Costco Shopper Feedback" Subject: Extended for a day!

The loss or impairment of the ability to feel anything touched is called tactile anesthesia. Paresthesia is a sensation of tingling, pricking, or numbness of the skin that may result from nerve damage and may be permanent or temporary. Two types of somatosensory signals that are transduced by free nerve endings are pain and temperature. These two modalities use thermoreceptors and nociceptors to transduce temperature and pain stimuli, respectively. Temperature receptors are stimulated when local temperatures differ from body temperature. Some thermoreceptors are sensitive to just cold and others to just heat. Nociception is the sensation of potentially damaging stimuli. Mechanical, chemical, or thermal stimuli beyond a set threshold will elicit painful sensations. Stressed or damaged tissues release chemicals that activate receptor proteins in the nociceptors. For example, the sensation of heat associated with spicy foods involves capsaicin, the active molecule in hot peppers. Low frequency vibrations are sensed by mechanoreceptors called Merkel cells, also known as type I cutaneous mechanoreceptors. Merkel cells are located in the stratum basale of the epidermis. Deep pressure and vibration is transduced by lamellated (Pacinian) corpuscles, which are receptors with encapsulated endings found deep in the dermis, or subcutaneous tissue. Light touch is transduced by the encapsulated endings known as tactile (Meissner) corpuscles. Follicles are also wrapped in a plexus of nerve endings known as the hair follicle plexus. These nerve endings detect the movement of hair at the surface of the skin, such as when an insect may be walking along the skin. Stretching of the skin is transduced by stretch receptors known as bulbous corpuscles. Bulbous corpuscles are also known as Ruffini corpuscles, or type II cutaneous mechanoreceptors. The heat receptors are sensitive to infrared radiation and can occur in specialized organs, for instance in pit vipers. The thermoceptors in the skin are quite different from the homeostatic thermoceptors in the brain (hypothalamus), which provide feedback on internal body temperature. ------------------------------ End of alt.music.moxy-fruvous digest V14 #5278 **********************************************
