US Patent:

56401434, Jun 17, 1997

Filed:

Feb 6, 1995

Appl. No.:

8/384580

Inventors:

Douglas D. Myron - Austin TX
Errol R. Williams - Round Rock TX
Charles C. Hardin - Austin TX
Timothy W. Woytek - Austin TX
Michael A. Stephens - Austin TX

Assignee:

MyTech Corporation - Austin TX

International Classification:

G08B 1300

US Classification:

340541

Abstract:

An occupancy sensor that provides improved performance by the inclusion of a microprocessor that controls the sensing transducers and processes the received signal to optimize desired detection performance. The occupancy sensor includes a quadrature detection technique and automatic sensitivity adjustment that reduce false detection caused by air flow, hallway traffic and other noise sources. A fault detection method executed periodically detects fault conditions in the sensor or sensing area caused by component failure or obstructions in front of the sensor. Transmitter power is varied depending on the size of the desired coverage area. Since various ambient parameters such as line voltage, light level, and temperature may be easily and usefully monitored, the microprocessor may use these variables to make intelligent decisions in controlling electrical loads, such as building lighting and ventilation.

International Classification:

G01R 2316

US Classification:

324 7621

Abstract:

The parameters of a digital signal are extracted by the application of autocorrelation and crosscorrelation techniques to effectively measure the frequency and time behavior of a digital signal. The method employs digital autocorrelation and crosscorrelation to determine these parameters. Autocorrelation allows the measurement of signal frequency by measurement of instantaneous signal phase. Crosscorrelation allows measurement of relative phase between two or more signals in two or more channels by measurement of instantaneous phase and by referencing the instantaneous phase to the autocorrelation function. The autocorrelation function and crosscorrelation function preserve relative amplitude and phase. Measurement of relative amplitude and phase allows direction finding calculation for any current class of system that uses amplitude and/or phase to derive angle or arrival. Signal time and frequency measurement at the output of a correlation receiver result in robust characterization of the parameters of the signal.

Abstract:

Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual players in a simulated environment of a virtual reality sporting event. In some embodiments, the user's actions and decisions are monitored by the simulated environment. The environment evaluates the user's performance, and provides performance feedback based on the user's decisions and timing. In one application, real life pitchers and their pitching data are tracked and replicated in a simulated pitching environment. A team of users may practice against a simulation of a pitcher they are about to compete against, swinging at pitches that they would see in a real game. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills. Some embodiments include various pitch recognition training, which may be against replicated real-life pitchers.
