Abstract: A method for quantification of the desynchronization between the clocks of two medical devices communicating wirelessly, for example, by HBC signals. The devices are separately clocked by slow clocks (CLK1/32k, CLK2/32k) and include selectively activated fast clocks (CLK1/10M, CLK2/10M). The method comprises: a) on a predetermined transition (T1) of a slow clock, transmission by one device of a synchronization query signal (SYNC) to the other device, b) counting of the pulses of the activated fast clock to detect a predetermined transition (T3) of the first slow clock, then c) transmitting from the other device to the first device a response signal (D1) and d) upon reception of the response signal, computing a temporal shift (OFFSET) according to the result (D1, D2) of the counting of the pulses of the fast clock. Two fast clocks, one on each device, also can be used.

Abstract: A system, method, and optical switch for communicating timing. A determination is made whether one of a number of data streams are available. Packets are received at a remote node in response to determining one of the number of data streams is available. A timing characteristic of the at least one of the packets is associated with a tick of a reference clock. The tick of the reference clock is extracted utilizing the timing characteristic of the at least one of the packets. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal. The clock signal is communicated to one or more interfaces for distributing.

Abstract: A wireless communication system broadcasts a control signal at a first frequency band from a base station and allocates additional frequency band(s) for transmitting data via terminal(s). A control signal at the first frequency band indicates the location of the additional frequency band(s) and is not transmitted over the additional frequency band(s). Wireless data transmission is simultaneously performed over the first frequency band and the additional frequency band(s). Each terminal receives the control signal, which is used in time-synchronizing frames between the wireless data transmission at the first frequency band and the wireless data transmission at the additional frequency band(s). The control signal also includes control data for managing wireless data transmission between the base station and the terminal(s) at the first frequency band, and is utilized instead of a control signal at the additional frequency band(s).

Abstract: In a wireless communication system, a central control unit 31 comprises a synchronizing means for synchronizing a frame for an base station-mobile station communication with that for an inter-mobile station direct communication based on control information used for the base station-mobile station communication, when a second frequency is used for the inter-mobile station direct communication which is different from a first frequency used for the base station-mobile station communication. The central control unit 31 also comprises an allocation means for allocating a band and a frequency for the inter-mobile station direct communication in accordance with an allocation request from a base station 30 or a mobile station 40. Frames for the base station-mobile station communication and the inter-mobile station direct communication are synchronized by utilizing control information 55 for the base station-mobile station communication instead of the conventional control information provided by the mobile station. The system allows a base station-mobile station communication to take place even when an inter-mobile station direct communication is conducted at a frequency other than that of the base station. As the base station controls the inter-mobile station direct communication, the burden on the mobile stations can be reduced, and a single base station can use multiple frequencies simultaneously.
