Abstract: A breath biofeedback method and system for encouraging a subject to modify respiration. The system includes a thoracic volume input module measuring thoracic volume data of the subject and a pattern module providing target breathing patterns in communication with a display generator. The display generator producing display information representing a displayable image including a first object having a first position determined as a function of the thoracic volume data and a second object having a second position determined as a function of the target breathing pattern and the thoracic volume data. The displayable image is designed such that when displayed on the display device the displayable image encourages the subject viewing the displayable image to modify respiration.

The wiring duct also includes a first aperture formed in the first side wall and extending into the base, and a second aperture formed in the second side wall and extending into the base.

Abstract: A method and system for optimizing the performance of a graphics processor system is disclosed. The graphics processor system includes multiple CPUs. The system has at least one application thread or master thread, and in addition each CPU is assigned a slave thread. In a first aspect, the method and system comprises assigning each slave to a particular CPU and causing the master thread to move between the processors to cause each slave thread to execute its graphics pipeline. This minimizes data motion due to application inputs being transferred from CPU to CPU. The method and system further includes providing a summary of relevant changes to graphics state to each slave, thus guaranteeing correct state without requiring synchronization around state updates. Accordingly a system and method in accordance with the present invention minimizes data motion during input and also minimizes synchronization associated therewith in a graphics processor system.

Abstract: The disclosed circuit determines whether a video signal is from a video tape player or a broadcast signal source by measuring jitter of the vertical synchronization pulses. In one embodiment, every other time interval between the vertical synchronization pulses is measured and saved as a count, and each count is compared to the preceding count to determine whether sufficient jitter is present to indicate that the video signal is from a local tape player. In another embodiment all intervals between the vertical synchronization pulses are measured and a predetermined number thereof are saved as counts. The even and odd counts are then analyzed separately, and the extreme count (the most deviant count) of each group is eliminated.

Abstract: Signal delaying means, included in the luminance channel of a color television receiver, are responsive to the television video signal processed in the receiver. A portion of the signal delaying means serves to equalize the time delays of signals processed in the chrominance and the luminance channels of the receiver. A plurality of differently delayed video signals are developed at signal coupling means associated with the signal delaying means. At least two of the delayed video signals, spaced apart in time by a predetermined interval inversely related to a frequency at which it is desired to relatively attenuate the video signals, are combined to determine the peaking characteristics of the luminance channel. At least one other of the delayed video signals is used to produce a signal to control the bandwidth characteristics of the luminance channel.

Abstract: A single frame color encoding/decoding system for video cassette or film chain applications is disclosed which requires neither an unusually stable transport mechanism, nor a color television camera in the playback system. The color content of the scene modulates two high frequency (e.g., 1,000 lpi) spatial carriers in the encoded transparency arranged in quadrature. A monochromatic light source projects, a seriatim, a set of transparencies. A grating is rigidly fixed to the frame of a scanner adjacent to the transparency. The grating consists of a superposition of two unmodulated low frequency (e.g., 300 and 400 lpi) spatial carriers also oriented in quadrature. The color content of the scene is optically transferred from the transparency onto relatively stable and low frequency spatial carriers of the grating. A focusing lens, situated along the optical path, obtains a diffraction pattern of the product of the transparency and the grating in the Fourier transform plane.
