Patent number: 8363512Abstract: Sound and image are sampled simultaneously using a sound/image sampling unit incorporating a plurality of microphones and a camera. Sound pressure waveform data and image data are stored in a storage means. Then the sound pressure waveform data are extracted from the storage means, and a graph of a time-series waveform of the sound pressure level is displayed on a display screen. A time point at which to carry out a calculation to estimate sound direction is designated on the graph, and then sound direction is estimated by calculating the phase differences between the sound pressure signals of the sound sampled by the microphones, using the sound pressure waveform data for a calculation time length having the time point at the center thereof. A sound source position estimation image having a graphic indicating an estimated sound direction is created and displayed by combining the estimated sound direction and the image data sampled at the time point.Type: GrantFiled: February 26, 2010Date of Patent: January 29, 2013Assignee: Honda MotorsInventors: Masanao Owaki, Takefumi Zaima, Koji Mase

Patent number: 5465403Abstract: A radio receiver of synthesizer type having a phase-locked loop therein and capable of selecting a desired broadcasting station by frequency conversion of a reception signal in conformity with an oscillation signal obtained from the phase-locked loop. The receiver includes a data table including frequency data for receiving programs from broadcasting stations, and time data indicative of the broadcast start time of each station; a timer circuit; a memory for the timer; and station select keys. When desired frequency data has been selected out of the data table by depressing one of the select keys for timer reservation, the selected frequency data and the time data corresponding thereto are read out from the data table and are written in the timer memory.Type: GrantFiled: February 4, 1994Date of Patent: November 7, 1995Assignee: Sony CorporationInventor: Masanao Owaki

Patent number: 5101508Abstract: A radio receiver receives a radio broadcast by performing a frequency conversion on the basis of an oscillation signal from a phase locked loop. Specifically, a memory has a data table including broadcasting station data, broadcasting time data, and frequency data necessary for receiving a particular radio broadcast at the broadcasting time. A timer and a key are provided for selecting a broadcasting station. When the key is operated, a key output and time data indicated by the timer are supplied to the data table as input data to indicate the broadcasting station on the data table. The corresponding frequency data is thereupon read out of the data table. The frequency data thus read out is supplied to the phase locked loop, whereby a frequency indicated by the frequency data is selected as the frequency for reception.Type: GrantFiled: June 4, 1991Date of Patent: March 31, 1992Assignee: Sony CorporationInventor: Masanao Owaki

Patent number: 4051446Abstract: A temperature compensating circuit for use with a crystal oscillator has a first bridge circuit for generating a first DC voltage with a linear functional temperature characteristic, a second bridge circuit for generating a second DC voltage with a quadratic functional temperature characteristic and a circuit for multiplying the first DC voltage and the second DC voltage so as to produce a DC voltage with a cubic functional characteristic. In this case, the DC voltage with the cubic functional characteristic is supplied to an oscillator circuit so as to compensate for variations in frequency of the crystal oscillator caused by temperature changes over a wide range thereof.Type: GrantFiled: April 16, 1976Date of Patent: September 27, 1977Assignee: Sony CorporationInventor: Masanao Owaki
