"I just wanted to say thank you for the work you do on [the videos.] Taking concepts that are common in the high school curriculum for physics, and breaking each aspect down into easy-to-understand language for both ends of the comprehension spectrum. I can personally say that you have ...
A video recorder, in which the sound signal is recorded by frequency modulation of a sound subcarrier (T1, T2) within the frequency spectrum of the modulated vision carrier (B). According to the invention, the frequency of the sound subcarrier (T1, T2) is switched between two values from...
and it can record and encode up to 16 full D1 video streams. Each channel supports motion, blind, video loss and night detection, and the display overlay supports region blanking. Eight sensor inputs, eight relay outputs and a serial RS-485/422 interface are available as an add-on module...
One main microphone was positioned ~0.5 inch away from the participant’s mouth. The microphone signal was sampled at 100 kHz each. The data were recorded on a laptop computer using a National Instruments NI-DAQ 6036E PCMCIA card. The audio sample clock was hardware-synchronized to the MR...
(6-6.5 MHz). In picture trans-mission a light spot passes sequentially over a fixed image. The rays reflected from the latter impinge on a photoelectric converter, thus creating video signals. The highest frequency in the video-signal spectrum is a function of the rate at which the image ...
1.A video-actuated system for creating an interactive environment on an interaction surface for a participant, comprising:at least one energy source capable of generating electromagnetic energy in a relatively limited wavelength range, wherein the at least one energy source is positioned such that ...
