Patent number: 8675452Abstract: Improved systems and methods for timing athletic events. A radio-based starter unit and a radio based timer unit communicate wirelessly via radio. Push buttons/switches and lights and a speaker in the units provide an intuitive, easy to use interface. Handshaking occurs between the starter unit and the timer unit, and lights indicate that the event is ready to start. Real time clocks in the units are synchronized. Upon detection of race or other event start, such as from a starter's pistol, information indicative of the race start time is transmitted from the start unit to the timer unit. A camera in communication with the timer unit provides video frames, and the timer unit encodes and inserts elapsed time information in the video frames, which are then output from the timer unit for review and analysis on a computer.Type: GrantFiled: January 3, 2011Date of Patent: March 18, 2014Assignee: Flashtiming LLCInventors: J.

Patent number: 5553080Abstract: In a speech decoding apparatus (100) supplied with an input speech signal (101) comprising successive blocks, each comprising a digital speech signal and an error detecting code signal, an error detector (8) detects an error in the digital speech signal by the error detecting code signal for each block to produce error detection pulses whenever the error detector detects the error. The error detector also produces the digital speech signals of the blocks. A speech decoder (9) decodes the digital speech signals of the blocks into an analog speech signal. A measuring circuit (102) measures, as a measured value, the number of the error detection pulses during a predetermined time interval. A comparator (15) compares the measured value with a reference value to produce a command signal when the measured value is greater than the reference value. A generator (12) generates an alarm signal in response to the command signal.Type: GrantFiled: January 31, 1995Date of Patent: September 3, 1996Assignee: NEC CorporationInventor: Ryuhei Fujiwara
