Abstract:
Communication between a wireless communication apparatus and a receiver using a plurality of communication slots is realized. Further, if trouble occurs during performing time-division wireless communication between the wireless communication apparatus and the receiver using the plurality of communication slots, the communication is continued while maintaining the same or similar communications traffic rate. A series of data is assigned to a plurality of communication slots in a first communication carrier, and communication is performed through the plurality of communication slots. If trouble occurs in a communication slot out of the plurality of communication slots, the communication is continued after changing the troubled communication slot to a communication slot of another communication carrier or another communication slot.
Abstract:
An opening and closing device comprises a powered sliding unit, a powered closing unit in the slide door, a first terminal connected to a battery on the body, a second terminal connected to the closing unit, a handle switch provided in the door for detecting actuation of an open handle, a controller provided in the body for operating the sliding unit, a wireless apparatus for transmitting a radio signal to the controller when the switch detects the actuation of the handle. The second terminal electrically contacts with the first terminal when the door is closed. The device has a wire apparatus composed of a first wire line for connecting the first terminal and the controller, and a second wire line for connecting the second terminal and the handle switch. The controller operates the sliding unit to open the door when the controller recognizes actuation of the handle through only the wire apparatus or through both the wire apparatus and the wireless apparatus, and the controller operates the sliding unit to close the door when the controller recognizes actuation of the handle through only the wireless apparatus.
Abstract:
A portable terminal device includes an information processing unit having a CPU which is a non-operating state, and an interface unit. When a data informing transmission of valid data is received from an external unit, the interface unit requests the external unit to stop the transmission of the valid data. At the same time, the interface unit transmits serial dummy data to the information processing unit. When the CPU is switched from a non-operating state to an operating state in response to reception of the serial dummy data, the interface unit requests the external unit to restart the transmission of the valid data. The interface unit transmits the valid data the information processing unit in serial. The CPU processes the valid data.
Abstract:
A compression/decompression method for image data allows addition of a code amount control amount in units of data of one block without necessitating an excessive header capacity. In compression, a quantization conversion coefficient of a quantization conversion coefficient set is replaced with a code amount control amount, and a resulted quantization conversion coefficient set is coded, whereafter a quantization coefficient of a quantization coefficient set corresponding to the code amount control amount of the quantization conversion coefficient set is changed to 0. In decompression, the quantization coefficient set is extracted, and coded data are decoded in units of data of one block. Then, the code amount control amount is extracted from the quantization conversion coefficient set of the decoded data.

Abstract:
This invention has as its object to set a one-to-one relationship upon establishing a wireless communication channel between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information even in an environment including a plurality of wireless communication devices, and to assure simple user's operations at least until the communication channel is established. To this end, when the user inputs a wireless communication channel establishment instruction to both a digital camera and printer having wireless communication functions, these devices execute wireless communication establishment processes within an allowable time period which is specified by a time set in a timer and a retry count. When the devices can seize each other within that time period, the communication channel is established. After that, the digital camera sends a sensed image to the printer, which prints the sensed image.
