Publication number: 20190305846Abstract: Disclosed herein is a receiver including a receiver circuit, a control circuit, and a wireless communications circuit. The control circuit retrieves identification information and content information from a plurality of transmitters based on an output of the receiver circuit. The control circuit retrieves, when having failed to retrieve content information from the plurality of transmitters, identification information from at least two of the plurality of transmitters, identifies one of the at least two of the plurality of transmitters as a target transmitter in association with the retrieved identification information, and also identifies another one the at least two of the plurality of transmitters as a non-target transmitter in association with the retrieved identification information. The wireless communications circuit transmits the control signal to allow the target transmitter to transmit the second optical signal and cause the non-target transmitter not to transmit the second optical signal.Type: ApplicationFiled: March 18, 2019Publication date: October 3, 2019Inventors: Shojiro KIDO, Teruhito TAKEDA, Hiromichi GOTO, Kazuo ITOH, Hiroyuki NISHINO

Publication number: 20180295691Abstract: An illumination light communication apparatus to be connected to a light source that emits illumination light due to a current from a constant current generation device, and that modulates the illumination light includes: a switch connected in series to the light source; a signal generator circuit that generates a binary communication signal which controls ON and OFF states of the switch to modulate the illumination light; a current suppression circuit that is connected in series to the light source and the switch, and that suppresses the current flowing in the light source so that a current setting value corresponding to a reference value is not exceeded; and a controller that can change an ON duty ratio of the switch through the communication signal. The controller changes the ON duty ratio of the switch during a transition period in which a current flowing in the current suppression circuit changes.Type: ApplicationFiled: April 2, 2018Publication date: October 11, 2018Inventors: Teruhito TAKEDA, Shigeaki YAMASAKI, Shojiro KIDO, Kazuo ITOH, Hiromichi GOTO, Hiroyuki NISHINO

Patent number: 9369053Abstract: In a power supply device, a primary winding of a transformer is connected in series to a main switching element, and is connected in parallel to a series circuit of a resonance capacitor and a sub switching element. A secondary winding of the transformer is connected in series to a series circuit of a rectifying element and a resonance inductor. The capacitance of the resonance capacitor and the inductance of the resonance inductor are each set such that, when the sub switching element is in an on state, the waveform of the voltage that is generated between the first main terminal and the second main terminal of the main switching element takes a protruding curve shape, the voltage being generated due to a resonance phenomenon of at least the resonance capacitor and the resonance inductor.Type: GrantFiled: February 20, 2015Date of Patent: June 14, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kiyoshi Ogasawara, Takafumi Fujino, Hiromichi Goto, Teruhito Takeda, Satohiko Hosomi, Kei Mitsuyasu, Katsuyuki Doi, Hideaki Abe
