20090283679 | REFLECTIVE COLLECTION-TYPE LIGHT RECEIVING UNIT AND LIGHT RECEIVING APPARATUS FOR SPATIAL LIGHT COMMUNICATIONS - The reflective collection-type light receiving unit of the present invention is a reflective collection-type light receiving unit having a light receiving element which receives spatial light on which an information signal is superimposed after being reflected and collected via a concave mirror. The light receiving element is arranged approximately at the center inside the concave mirror, with the light receiving plane thereof facing to the reflection plane of the concave mirror. A pair of electrode leads connected to both electrodes of the light receiving element are extended so as to be opened from the center on the front plane of the concave mirror to both sides and connected to a light receiving circuit by way of the lateral plane of the concave mirror. | 11-19-2009 |
20090245806 | VISIBLE LIGHT COMMUNICATION APPARATUS - A visible light communication apparatus is constituted with a transmitter for illuminating and projecting visible light on which an information signal is superimposed from a lamp fitting and a receiver for receiving the visible light to take out the information signal superimposed on the visible light. The transmitter modulates a transmission information signal, driving a light projecting element of the lamp fitting so as to superimpose the transmission information signal on the visible light of the lamp fitting, thereby radiating white light containing a blue light component as visible illumination light. The receiver receives the white visible light containing the blue light component radiated from the transmitter and generates a receiving information signal from the light receiving signal on a receiving circuit. A blue light photodiode which receives blue light at the highest sensitivity to output a light receiving signal is used as a light receiving element of the light receiving unit. The lamp fitting for radiating the white light containing the blue light component on the side of the transmitter as visible illumination light and the blue light photodiode for receiving blue light on the side of the receiver at the highest sensitivity can be used to perform visible light communications at high speed, while illuminating by the white light. | 10-01-2009 |
20090203286 | AUDIO SIGNAL RECEPTION TYPE VOCALIZING TOY AND VOCALIZING TOY APPARATUS - An audio signal reception type vocalizing toy is worn and used by a user as a visitor in a customer attraction facility. A light receiving unit having a light receiving element for receiving visible light through a condensing lens is attached to the front of a wear type toy body. An amplifier and filter circuit are provided in the wear type toy body, the amplifier amplifying a signal output from the light receiving unit, and the filter circuit integrating a digital signal output from the amplifier into an analog audio signal and outputting it to a speaker(s). The speaker(s) is (are) attached into the wear type toy body. When the user wears the vocalizing toy and directs the light receiving unit in the front of the wear type toy body to a visible light source of a visible light transmitter for superimposing and projecting an audio signal on visible light in the customer attraction facilities, the light receiving unit receives the visible light and picks up the audio signal contained in the light reception signal, and sound containing music, voice, etc., is generated by the speaker. | 08-13-2009 |
