  • Patent number: 7620969
    Abstract: This invention provides a program information display control apparatus and method, a remote control device, a program, and a storage medium, which can simultaneously display the contents and detailed information of specific programs that follow predetermined rules such as a time band, genre, and the like. To this end, detailed program information associated with each of programs to be displayed on an EPG is acquired from an antenna (1101) and tuner (1102). The acquired program information is stored in a memory (1150) via a decoder (1103). A viewer designates programs, details of which are to be displayed, using a remote controller (12), and the memory (1150) is searched for detailed program information of a plurality of designated programs. An image controller (1121) simultaneously displays a plurality of pieces of program information associated with these designated programs at their display positions on the EPG displayed on a display unit (1122).

  • Patent number: 7536707
    Abstract: A visual communications system and a method of controlling the same for pausing the screens of two terminals at quite the same image. Video communications terminals receive the same channel in their respective broadcast program receiving units. A first video communications terminal temporarily stores the video of the received channel in the temporary storage memory. When a user pauses operation of the first terminal, it temporarily stores a screen pause time obtained by adding a predetermined time to the current time, and transmits a screen pause command and the screen pause time to a second video communications terminal. The second terminal pauses the video at the screen pause time if possible in time. Otherwise, it pauses the video immediately, and transmits a response with its own image pause time to the first terminal. The first terminal displays an image corresponding to the image pause time of the second terminal memory.

  • Patent number: 7522087
    Abstract: A display apparatus includes a receiving unit, a communication unit, a display unit and a control unit. The receiving unit receives from a remote control device position data corresponding to a contact position. The contact position is detected by a track pad unit and the track pad unit is included in the remote control device. The communication unit receives from an external device an operational panel used to control the external device. The display unit displays the operational panel received by the communication unit. The control unit controls the operational panel using the position data received by the receiving unit. The control unit allocates operable elements included in the operational panel to the track pad unit without changing an array of the operable elements included in the operational panel.

  • Patent number: 7482769
    Abstract: A high-level ECU generates a torque command value T1 according to an output request to an electric motor. A low-level ECU calculates a torque command value T2 for correcting the original torque command value T1 according to the operational state of the electric motor and, according to a final torque command value Tf that is set by combining the torque command values T1 and T2, the electric motor is controlled. The high-level ECU receives from the low-level ECU the torque command value T2 and a motor state quantity transmitted thereto and, by a comparison between an actual torque value Tj determined from the motor state quantity and the final torque command value Tf determined with the torque command value T2 reflected thereto, abnormality in electric motor control is detected.

  • Patent number: 7443116
    Abstract: A normal map determines a carrier frequency used for switching control of an inverter controlling driving of a motor generator, in accordance with the state of operation of the motor generator in a normal operation. In a stall state in which the driver is pressing both the accelerator pedal and the brake pedal, the switching frequency is determined using an element protection map, in place of the normal map. When the element protection map is used, in the state of operation corresponding to the stall state, the carrier frequency is set to a protection frequency lower than a normal frequency. Therefore, in an electric vehicle having an electric motor (motor generator) as a driving source for the vehicle, it becomes possible to avoid temperature increase of a power semiconductor device forming an electric power converter for controlling driving of the electric motor.
