Patent number: 9905250Abstract: A voice detection method which makes it possible to detect the presence of voice signals in an noisy acoustic signal x(t) from a microphone, including the following consecutive steps: calculating a detection function FD(?) based on calculating a difference function D(?) varying in accordance with the shift ? on an integration window with length W starting at the time t0, with: a step of adapting the threshold in said current interval, in accordance with values calculated from the acoustic signal x(t) established in said current interval; searching for the minimum of the detection function FD(?) and comparing the minimum with a threshold, for (?) varying in a predetermined time interval referred to as current interval so as to detect the possible presence of a fundamental frequency F0 that is characteristic of a voice signal in said current interval.Type: GrantFiled: November 27, 2014Date of Patent: February 27, 2018Assignee: ADEUNIS R FInventor: Karim Maouche

Patent number: 8786416Abstract: A control installation of the playing time of a sporting event, in particular of the basketball game type, includes a portable acquisition and detection system of a whistle signaling the stoppage of the playing time, the portable system converting the acoustic signals into digital signals, digitally processing these digital signals and delivering a digital refereeing signal in response to the detection of the whistle. The control installation further includes a fixed system for controlling the playing time in digital radio connection with the portable system and a controller for controlling the stoppage and/or restarting of a stopwatch counting down the playing time in response to the reception of the digital refereeing signal.Type: GrantFiled: November 2, 2010Date of Patent: July 22, 2014Assignee: Adeunis R FInventors: Pascal Saguin, Pascal Champaney, Philippe Turlier

Patent number: 8705495Abstract: The invention relates to a communication method using time-division multiplexing, which enables permanent communication between user terminals. One of the terminals is a master terminal, while the others are slave terminals. The transmission channel is divided into consecutive cycles, and each cycle is divided into timeslots. Each slave terminal identifies, in a listening mode, a free timeslot in the current cycle (6) and, in a transmission mode, transmits data in the identified timeslot during at least one subsequent cycle (7). As soon as the slave terminal stops transmitting, the identified slot becomes free again.Type: GrantFiled: November 13, 2009Date of Patent: April 22, 2014Assignee: Adeunis R FInventors: Pascal Champaney, Pascal Saguin

Publication number: 20130235702Abstract: Installation (1) for controlling the playing time of a sporting event, in particular of the type found in basketball, comprising:—a portable system (2) for picking up and detecting a whistle blow (S4) that signals a stoppage in the playing time, said portable system converting the audible signals into digital signals, digitally processing these digital signals and outputting a digital refereeing signal (S23) in response to the detection of the whistle blow; and—a fixed system (3) for controlling the playing time, having a digital radio connection to the portable system and comprising control means (31) that stop and/or start a clock (32) that counts down the playing time in response to the reception of the digital refereeing signal. The invention also relates to just the portable system and to just the fixed system specially designed for the portable system, and also to a time-multiplexing digital audio communications terminal incorporating such a portable system.Type: ApplicationFiled: June 24, 2011Publication date: September 12, 2013Applicant: ADEUNIS R FInventors: Pascal Saguin, Pascal Champaney, Philippe Turlier
