20090041009 | IP TELEPHONE TERMINAL, IP TELEPHONE SYSTEM AND RECORDING MEDIUM - An IP telephone terminal outputs a call request for communication with a prescribed terminal and, if it is determined that connection failed, records the input voice. Thereafter, the IP telephone terminal determines that the prescribed telephone terminal has reached a state connectable through IP network, outputs a call request for communication with the prescribed terminal and if connection is determined to be established, transmits the recorded voice to the prescribed terminal. | 02-12-2009 |
20110010166 | MOBILE COMMUNICATION TERMINAL CONNECTABLE TO NETWORK - A mobile communication terminal includes a first communication unit connectable to a first communication apparatus via a first network using a first wireless communication protocol, a second communication unit connectable to a second communication apparatus via a second network using a second wireless communication protocol different from the first wireless communication protocol, a controller configured to control the first and second communication units, a microphone, and a speaker. The controller transmits first data, addressed to the second communication apparatus, to the second network, transmits second data, addressed to the first communication apparatus, to the first network, causes the speaker to convert into corresponding voice a second voice signal addressed to the mobile communication terminal, and transmits a first voice signal. | 01-13-2011 |

20140368754 | PROJECTOR - A projector includes a light source, a projection component, a photodetector, and an inclination calculator. The light source outputs light. The projection component projects an image on a projection surface by scanning the light outputted by the light source at an angle to the projection surface. The photodetector detects, as a reflected light, the light that has been scanned by the projection component and reflected by a detection object within a light detection range of the photodetector. The light detection range is set to a predetermined range in a direction perpendicular to the projection surface. The inclination calculator calculates an inclination angle of the detection object in a sub-scanning direction of the light based on a position of the detection object on the projection surface and a number of times the reflected light is detected while scanning in the sub-scanning direction. | 12-18-2014 |
