Patent number: 11679677Abstract: A device control system includes a first input device and a gaze detector. The first input device allows a command to be entered with respect to a target device selected from one or more devices. The gaze detector detects a user's gaze direction. The gaze detector determines, based on the gaze direction detected by the gaze detector, one device, selected from the one or more devices, to be the target device. A gaze detector makes the target device change, based on the gaze direction detected by the gaze detector, the type of processing to be performed in accordance with the command entered through the first input device.Type: GrantFiled: March 25, 2021Date of Patent: June 20, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kouji Ueda, Shigeo Nakamura, Kenji Matsui, Takehiko Yasuda, Yoshiteru Matsushita

Patent number: 8174628Abstract: A flexible LCD (2) is a flexible display. The flexible LCD (2) is pulled out from an upper cabinet to change a display area of the flexible LCD (2). An amount-of-sliding detecting section (4) measures the pullout amount (amount of sliding) of the flexible LCD (2) when the flexible LCD (2) is pulled out from a mobile terminal unit (1) or is retracted into the mobile terminal unit (1). A display controller (3) causes the flexible LCD (2) to display in a manner responsive to the amount of sliding that is measured by the amount-of-sliding detecting section (4). The foregoing makes it possible to utilize effectively the display having a display area that is revealed when the display is pulled out.Type: GrantFiled: August 30, 2006Date of Patent: May 8, 2012Assignee: Sharp Kabushiki KaishaInventors: Yoshiteru Matsushita, Masanori Honda, Kiyoshi Suzuki, Minoru Takemoto

Publication number: 20070242887Abstract: A portable terminal that can execute the image matching without any special operation is provided. The portable terminal has an imaging means, and comprises a state detecting means that detects a state of the portable terminal, a matching information storing means that stores image information for matching, and a matching means that matches image information acquired by the imaging means with the image information stored in the matching information storing means. When the state detecting means detects that the state of the portable terminal is a predetermined state, the state detecting means judges that the terminal becomes to be in a checkable state and causes the imaging means to acquire image information.Type: ApplicationFiled: October 7, 2005Publication date: October 18, 2007Applicant: Sharp Kabushiki KaishaInventors: Yoshiteru Matsushita, Hideyuki Yasuda, Naoto Satokata

Patent number: 7149266Abstract: An OFDM receiver includes an offset compensator (14) compensating for a frequency offset in a received OFDM signal. The offset compensator (14) includes a memory (51) storing two reference signals corresponding to arbitrary portions in the start symbol of the OFDM signal. A cross correlation value between the received OFDM signal and each of the two reference signals is calculated by a cross correlator (52, 53). Each peak position is detected by a peak detector (54). A frequency offset estimate value of the received OFDM signal is estimated by a frequency offset estimation circuit (55) based on the cross correlation value at each detected peak position. A phase rotation circuit (37) compensates for the frequency offset of the received OFDM signal based on the estimated frequency offset estimate value.Type: GrantFiled: May 15, 2000Date of Patent: December 12, 2006Assignee: Sharp Kabushiki KaishaInventors: Kimihiko Imamura, Yoshiteru Matsushita, Hidekazu Tsuboi, Takashi Yoshimoto
