Adding a general overall exposure of light to a photosensitive material to alter the material's response to a captured image is a long-known technique. Photographer Ansel Adams describes the use of "pre-exposure," to make details visible in a darker area of an image, in his text The Negative (rev. ed. 1959). For more, study astronomic ...
A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4 ms + 1.0 ms = 3.4 ms, corresponding to a shutter speed of about 1 ⁄ 290 s. However some time is ...
Thomas Zimmerman invented the prototype of the DataGlove and began looking for other people to help work on it. The device used 6502 microcontrollers. Zimmerman met Mitch Altman and asked him to join VPL part-time because Altman knew how to program the microcontrollers. [5] The system was wired to a computer.
The generic FLASH technique emerges as a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the NMR signal (recorded as a spatially encoded gradient echo) with a rapid repetition of the basic sequence. The repetition time is usually much shorter than the typical T1 relaxation time of the protons in biologic ...
The laser flash method was developed by Parker et al. in 1961. [1] In a vertical setup, a light source (e.g. laser, flashlamp) heats the sample from the bottom side and a detector on top detects the time-dependent temperature rise. For measuring the thermal diffusivity, which is strongly temperature-dependent, at different temperatures the ...
Jaron Zepel Lanier (/ ˈ dʒ eɪ r ɪ n l ɪ ˈ n ɪər /, born May 3, 1960) is an American computer scientist, [1] visual artist, computer philosophy writer, technologist, futurist, and composer of contemporary classical music.
In 1982 Thomas G. Zimmerman filed a patent (US Patent 4542291) on an optical flex sensor mounted in a glove to measure finger bending. [4] Zimmerman worked with Jaron Lanier to incorporate ultrasonic and magnetic hand position tracking technology to create the Power Glove and Data Glove, respectively (US Patent 4988981, filed 1989).
