摘要:
An assembly, and an associated method, for an ad hoc network, such as an independent basic service set defined in an IEEE 802.11 protocol specification. A channel map is created and maintained at each mobile station of the ad hoc network. The channel map is populated with channel characteristic indicia of channel frequencies that might be available upon which to be used in the ad hoc network to effectuate communications between the mobile stations. Information related to the channel map created and maintained at each of the mobile stations is exchanged, and any of the mobile stations is selectable to form a DFS owner that defines the channel frequency to be used upon which to define a communication channel for communications in the network.
摘要:
Apparatus, and an associated method, for requesting a measurement to be performed at a communication station of a radio communication system, such as a WLAN. A measurement request message is generated at a requesting station. The measurement request message includes fields identifying a selected measurement type and a field identifying a duration period for which the measurement is requested to be made. The duration period is mandatory or non-mandatory. The request message is communicated to a communication station whereat the message is detected and the values contained therein are identified. Selection is made at the communication station to which the message is delivered whether to perform the requested measurement for the requested duration period. If the requested duration period is non-mandatory, the communication station is able to select a duration period of lesser length during which to perform the requested measurement.

A microprocessor based system provides a media player with access to remotely-stored digital media content and/or its associated metadata. The system is capable of accessing the content, so that the media player is provided, by the system, with a suitable interface, accessible by that media player, for interacting with the content. The system may be packaged as a USB memory stick and can be inserted into, for example, a PC running a legacy media player with no intrinsic ability to access remotely stored content. The PC can in this way be enabled to access the remote content.

Two new polymorphic forms of (E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)amino]pyrimidin-5-yl](3R,5S)-3,5-dihydroxyhept-6-enoic acid tris(hydroxymethyl)methylammonium salt (1), processes for making them and their use in the production of a pharmaceutical useful in the treatment of, inter alia, hypercholesterolemia, hyperlipoproteinemia and atherosclerosis are described.
摘要:
The invention provides a method of providing secure data communication between a client device and a network device, wherein the method comprises arranging a periodically varying broadcast code (N) to be transmitted such that the network and client devices have knowledge of the broadcast code (N), providing the network and client devices each with the same secret key code (K) and encryption/decryption algorithm, wherein the algorithm is arranged to encrypt and decipher a encrypted transmission data code used for network authentic data transmissions between the client and network devices, and wherein the encrypted data code is generated from a combination of the data and a secret key (X) which is itself derived from a combination of the secret key code (K) and broadcast code (N). One embodiment provides that the broadcast code (N) is transmitted on request by a network/client device. Another embodiment provides that the ACK frame of a data transmission between client/network devices is used to send notifications of the fact that the broadcast code (N) has changed.
摘要:
The invention relates to a method for controlling the operation of a short-range wireless terminal capable of operating in a first beacon-based network and in a second beacon-based network, and having an active state and a power save state in the first beacon-based network. For seamless operation in the two networks, the terminal moves to a power save state with respect to the first beacon-based network if operation in the second beacon-based network is required. However, the first beacon-based network is only informed that the terminal moves to a power save state and instead of powering down, the terminal becomes active in the second beacon-based network.
