摘要： A transmitter for transmitting an intermittent sequence of messages to maintain synchronization between the transmitter and a receiver. The transmitter includes control apparatus which provides messages for transmission, each message forms part of a sequence of messages and includes control information and timing information, and transmission apparatus which transmits each message. A receiver for synchronizing with a sequence of the transmitted messages. The receiver includes receiver and synchronization apparatus responsive, when enabled, to the control information in the message to indicate to the control apparatus reception of the message. The control apparatus controls power conservation by disabling the receiver and synchronization apparatus for a period of time dependent upon the timing information and enabling the receiver and synchronization apparatus to receive a following message in the sequence.

摘要： A device for communicating with other devices to allow them to access applications, comprises: at least a first application; authentication means for authenticating a communicating device; and access control means accessible by a communicating device requesting access to the first application without the communicating device having been authenticated by the authentication means. The device is further arranged to arbitrate whether access of the communicating device to the first application is granted or refused wherein if the arbitration requires an authentication of the communicating device, the access control means instructs the authentication means to authenticate the communicating device.

摘要： A Bluetooth radio transceiver, for receiving isochronous data, comprising: receiving means for receiving data; determining means for determining whether the received data has been correctly or incorrectly received; validation means for determining whether the received data is current; and transmission means, for transmitting, in response to received data, a positive acknowledgement of reception when the received data has been correctly received, a negative acknowledgement when the received data has been incorrectly received and the received data is current and a positive acknowledgement when the received data has been incorrectly received and the received data is not current. The determination of whether data is current occurs at the receiver as opposed to the transmitter.

摘要： A transmitter, for controlling at least one receiver by intermittently transmitting groups of messages. The transmitter includes a controller arranged to provide intermittently groups of messages for transmission. Each of said groups includes a plurality of messages in series and separated by time intervals, wherein each of the plurality of messages in a group includes control information such that control of the receiver can be effected by reception of any one of the plurality of messages in the group. The invention increases the efficiency with which control messages can be transmitted without markedly increasing the power consumption of transceivers in a radio frequency network.
