Publication number: 20160280135Abstract: In an embodiment, an animal detection system (11) includes a surround view system (12), a location determination system (13) and a processing module (14). The processing module (14) is configured to receive data from the surround view system (12) and receive data regarding the location of the vehicle (10) from the location determination system (13). The processing module (14) is configured to determine if the location of the vehicle (10) is within an animal zone, and if the location of the vehicle (10) is within an animal zone, to process data received from the surround view system (12). If the data from the surround view system (12) indicates the presence of an animal, the processing module (14) activates an alert (19).Type: ApplicationFiled: March 9, 2016Publication date: September 29, 2016Inventors: Louis-Marie AUBERT, Paul FLANAGAN, Rui GUERREIRO, Clifford LAWSON, Andreas PANAKOS, John POWELL, Carlos SILVA, Greg WINGFIELD

Patent number: 7817728Abstract: The present invention relates to a method for transmitting data in the form of at least one pulse sequence Tsgk (for k=1 to K). The method according to the invention includes at least one symbol decoding step in the course of which at least one modulation value Pwk representative of an amount of power carried by each pulse sequence Tsgk is computed and compared to at least one predetermined threshold value Thvk, which will be computed beforehand by equating a first and a second probability density function representing a likelihood for the transmitted signal to carry a first symbol and a likelihood for the transmitted signal to carry a second symbol, respectively. The method according to the invention enables to limit the processing time and power needed for performing the demodulation of a power-modulated UWB signal.Type: GrantFiled: November 30, 2004Date of Patent: October 19, 2010Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Stephane Paquelet, Louis-Marie Aubert, Claire Meunier

Patent number: 7792210Abstract: The present invention relates to a method for transmitting data in the form of at least one sequence Tsg of Ns pulses, each pulse being enclosed within a predetermined time chip Tc. The method according to the invention includes at least one symbol encoding step, in the course of which each pulse pj (for j=1 to Ns) of an ith pulse sequence Tsg is multiplied by a value Vi representative of a symbol to be carried by said sequence. By virtue of the invention, the information carried by the pulse sequence Tsg will essentially be represented by the power carried by this sequence Tsg, which power is related to the amplitude of the pulses pj. This information may then be recovered by a receiver without said receiver having to map precisely, with respect to time, the received pulse sequences.Type: GrantFiled: September 22, 2004Date of Patent: September 7, 2010Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Stephane Paquelet, Louis-Marie Aubert

Patent number: 7613255Abstract: The present invention relates to a method for transmitting data by means of at least one pulse sequence carried by a radio signal, in the course of which a power value representative of an amount of power carried by said pulse sequence is computed. The method according to the invention provides estimated values of noise affecting the radio transmission and of an amount of power which would be carried by each pulse sequence in the absence of noise, respectively, prior to the determination of a threshold value to which the power value is to be compared. The knowledge of such estimated values enables to compute a threshold value adapted to the communication conditions affecting any given pulse sequence, and hence to perform an optimal demodulation of any power-modulated UWB signal.Type: GrantFiled: August 24, 2005Date of Patent: November 3, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Louis-Marie Aubert, Stephane Paquelet

Patent number: 7551891Abstract: The invention relates to a method for transmitting at least one sequence of Np pulses over Np time windows, each pulse being enclosed within a predetermined time chip Tc. The method according to the invention includes a signal detection step, in the course of which Np detection windows Dj. (for j=1 to Np) encompassing predetermined time chips are examined by performing correlations over said detection windows Dj of the received signal with at least a first and a second sinusoidal signal S1 and S2. The method according to the invention enables to limit the processing time and power needed for carrying out the detection step, which only requires to examine detection windows defined by a signature of a transmitter by using sinusoidal signals, instead of mapping the whole pulse sequence by means of a correlation with expected pulses.Type: GrantFiled: March 18, 2005Date of Patent: June 23, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Stephane Paquelet, Louis-Marie Aubert

Patent number: 7508879Abstract: A system to transmit data in the form of at least one pulse sequence modulated by symbol encoding units. The symbol encoding units include a plurality of signal encoders (ENCi) connected to a plurality of antennas, pulse generating units (PGi) for delivering a basic pulse sequence (PSQi), first energy splitting units (ENSPi) for splitting basic pulse sequence into sub-sequences (Psqi-PsqiK), signal modulating units (SGM1-SGMK) for applying to the sub-sequence a tunable coefficient, and combination units (CMBMi) for combining the sub-sequences (Tsgi1-TsgiK) into a signal (Tsgi) to be transmitted by the antenna (ANTi) to which the encoder (ENCi) is connected. Each signal encoder (ENCi) is linked to a single antenna (ANTi).Type: GrantFiled: July 18, 2005Date of Patent: March 24, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Jean-Baptiste Dore, Bernard Uguen, Stephane Paquelet, Louis-Marie Aubert

Publication number: 20060056504Abstract: The present invention relates to a method for transmitting data by means of at least one pulse sequence carried by a radio signal, in the course of which a power value PWk representative of an amount of power carried by said pulse sequence is computed. The method according to the invention provides estimated values Nek and Eek of noise affecting the radio transmission and of an amount of power which would be carried by each pulse sequence in the absence of noise, respectively, prior to the determination of a threshold value Thvk to which the power value PWk is to be compared. The knowledge of such estimated values Nek and Eek enables to compute a threshold value Thvk adapted to the communication conditions affecting any given pulse sequence, and hence to perform an optimal demodulation of any power-modulated UWB signal.Type: ApplicationFiled: August 24, 2005Publication date: March 16, 2006Applicant: MITSUBISHI DENKI KABUSHIKI KAISHAInventors: Louis-Marie Aubert, Stephane Paquelet
