摘要:
A communication device including circuitry configured to receive communication data transmitted/received between a transmitting device and a receiving device that is a transmission target of transmission data transmitted by the transmitting device by unicast, to determine whether data to be used for a process by the communication device is included in the received communication data, and to process the data to be used for the process by the communication device when the circuitry determines the data to be used for the process by the communication device is included in the received communication data. The circuitry is also configured to prevent the communication device from responding to the transmitting device, and to not relay the communication data received from the transmitting device to the receiving device, when the circuitry determines the data to be used for the process is included in the received communication data.

There is provided a communication apparatus including a communication unit that receives first communication data transmitted from a transmitting apparatus to a first receiving apparatus through unicast and second communication data transmitted from the transmitting apparatus to a second receiving apparatus, respectively and a processing unit that processes processing data included in the received first communication data and second communication data. When there is missing data in either of first processing data included in the first communication data and second processing data included in the second communication data, the processing unit executes processing using the other processing data in which there is no missing data, and the processing unit does not make the communication unit transmit a reply with respect to external apparatuses.

A wireless communication device includes: a data transmission unit that transmits data to one or more receiving terminals; and a communication mode determination unit that determines a communication mode in which the data is transmitted from the data transmission unit, wherein the communication mode determination unit selects a first communication mode in which unicast communication is used when the number of receiving terminals to which the data is transmitted is equal to or less than a predetermined number, and selects a second communication mode in which unicast communication is performed to one or some of receiving terminals as a destination and the other receiving terminals than the destination also receive packets in unicast communication when the number of receiving terminals to which the data is transmitted exceeds the predetermined number.

An image forming apparatus acquires an amount of deflection of the transporting sheet from a reference position thereof and calculates a required shift amount of the sheet. It determines whether or not the sheet is shifted frontward. If so, the image forming apparatus acquires a second specified shift value which is determined based on an urging force and the required shift amount using a second correction equation. Alternatively, if the sheet is shifted backward, the image forming apparatus acquires a first specified shift value which is determined based on the urging force and the required shift amount using a first correction equation. The image forming apparatus performs a registration roller shift correction based on the acquired first or second specified shift value.
摘要:
A portable terminal monitors a signal level of a short-range wireless signal from a wireless communication apparatus. If the signal level drops so low that a state of connection for short-range wireless communications cannot be maintained between the two apparatuses, use of predetermined functions of the portable terminal is limited. A short-range wireless communication facility of the portable terminal and the wireless communication apparatus move into a particular operation mode if communications do not occur therebetween at least for a predetermined time period. In monitoring the signal level of the wireless signal from the wireless communication apparatus in the particular operation mode, the portable terminal reduces a response speed at which to detect a signal level change. This causes the wireless communication apparatus to delay issuing a request for an increase in transmission power, thereby reducing unevenness of the working distance at which to alert a user to the unusual distance traveled between the two apparatuses or beyond which to limit the use of some functions of the portable terminal.

A head set apparatus capable of a wireless communication by a predetermined wireless communication system, wherein the predetermined wireless communication system includes at least a first communication mode which enables a data transfer with a partner apparatus to be communicated and a second communication mode for carrying out a wireless communication with the partner apparatus with a period shorter than that of the communication in the first communication mode while the wireless connected state remains; and the head set apparatus includes communication means for carrying out a wireless communication by the predetermined wireless communication system and control means for making the head set function as a head set when the communication state in the communication means is in the first communication mode and for making the head set function as a wireless key for security when the communication state is in the second communication.
摘要:
A reception apparatus and a reception processing method are proposed to improve a reception characteristic by compensating deterioration of transmission quality independently of the traveling speed of a terminal. When a transmission signal sent via a radio transmission path is received and data is demodulated by carrying out various kinds of reception processing on the received signal, the present invention can perform reception processing best suited to a radio transmission path whose state changes according to the traveling speed of the terminal itself by receiving traveling speed information from speed detection means for detecting the traveling speed of the terminal itself and controlling reception processing on the reception signal according to the traveling speed information.
