Abstract: Plural repeaters (1111 to 111n) are connected one another via a system bus (115), and each of which detects the state of another repeater by checking a signal transmitted over the system bus (115). When stopping the operation of home repeater (e.g., the repeater (1111)) which performs relaying process among wireless terminal devices (TA) to (TH), a secondary repeater (e.g., the repeater (1112)) set beforehand detects that the home repeater breaks down as the secondary repeater becomes unable to detect the signal over the system bus (115). The secondary repeater responds to the detection and bears the relaying process instead of the home repeater.

Abstract: Wireless terminal devices (TA) to (TH) each detects whether channel information received from each of repeaters (1111) to (111n) indicates an occupied state or an idle state, and when detecting a channel in an idle state, writes identification information of that channel in a RAM (23). The wireless terminal devices (TA) to (TH) each selects a piece of identification information of a channel among plural pieces of identification information of a channel written in the RAM (23) to start making a call to a channel of the selected identification information.

Abstract: There is provided a wireless communication system which causes a wireless terminal to select a relay device among plural relay devices connected together via a communication line when the wireless terminal attempts to communicate with another wireless terminal. The relay device has an information acquiring unit, a calling determining unit, and an information adding unit. The wireless terminal has an information analyzing unit which analyzes whether or not the own device is included in a communication counterparty of calling information when the calling information is included in communication information, a priority comparing unit which determines whether or not a priority level of the calling information is higher than that of a current communication when the own device is included, and a channel changing unit which changes a channel to that of another relay device of the calling information when the priority level of the calling information is higher.

Abstract: A source driver includes a dividing circuit, a start signal capturing unit, a pulse width determining unit and a control circuit. The dividing circuit produces a divided clock by dividing a basic clock signal. The start signal capturing unit captures the start signal at timing of the edge of the divided clock. The pulse width determining unit determines a pulse width of the start signal that is captured. The control circuit changes the timing to start capturing the data according to the pulse width of the start signal. With this structure, the latter source driver is able to adjust capturing timing to effective data timing input thereto, even though final data does not end at the falling edge of the divided clock signal.

Abstract: When a process of searching for assets stored in a memory card is selected, a controller of a printer sets searching icons associated with previously set searching-keywords as current searching icons (S110), and each time a memory card is installed in a reader/writer, acquires all keywords associated with assets, which are search objects, from the installed memory card (S170), collates the set searching-keywords with the acquired keywords (S200), and displays searching-keywords among the set searching-keywords, that do not match any of the acquired keywords in a manner that differs from a normal display (S210). A user can thus recognize that a searching-keyword that has been set is not contained in the memory card 18 before the user executes an actual search.
