Abstract: Time stamp replication within wireless networks is described. In an embodiment, a wireless station receives an input time stamp and uses this input time stamp to generate an output time stamp. The wireless station transmits the output time stamp to wireless stations in one of a number of groups which make up the wireless network. The output time stamp is generated to compensate for delays between receiving the input time stamp and transmitting the output time stamp such that output time stamp which is transmitted at a time T corresponds to the value that the input time stamp would have had if it had been received at time T (and not at a time earlier than T). This may, therefore, reduce or eliminate independent time stamp errors and jitter caused by multiple disparate systems and processes.

Abstract: A high definition timing synchronization function is described. In an embodiment, a wireless station generates a time stamp at a higher resolution than can be broadcast within a standard time stamp field in a frame. The generated time stamp is divided into two parts: the first part being included within the time stamp field and the second part being included within a vendor specific field in the same frame. The frame is transmitted by the wireless station and received by other wireless stations in the wireless network. If the receiving wireless station has the capability, it decodes both the time stamp field and the vendor specific field and recreates the higher resolution time stamp. This higher resolution time stamp is then used to synchronize the receiving wireless station and the transmitting wireless station by resetting a clock or by storing time stamps and corresponding clock values.

Abstract: A method of estimating the proximity of a first device to a second device in a network causes the first device to perform a first measurement in a first period during which a control message broadcasted over the network instructs devices in the network to not transmit during the first period, wherein the second device disregards the control message and transmits a first signal during the first period which is measured by the first device during the first period, and forms a measure of the proximity of the first device to the second device in dependence on a strength of the first signal.

Abstract: An injectable liquid composition for the treatment of a physical addiction includes naltrexone in the amount of 5%-95% of the total weight of the composition; at least two co-polymers in the amount of between 5%-95% of the total weight of the composition; and a biocompatible water miscible organic solvent in the amount of 5% to 50% of the total weight of the composition. The composition is adapted to form a gel-like mass when contacted with an aqueous environment and to dissolve at a predetermined rate to release a therapeutic naltrexone dose over a predetermined period of time.

Abstract: Methods and systems for wireless stations to wirelessly exchange configuration information using the vendor specific field of management frames (e.g. Wi-Fi™ probe request frames, Wi-Fi™ beacon frames or Wi-Fi probe response frames). Each wireless station can then use the configuration information to configure itself for a particular application or task. For example, the wireless stations may use the configuration information to determine the appropriate topology of a collection of wireless stations for the application or task. Using the management frames to exchange configuration information allows the wireless stations to exchange configuration information without being fully connected to a wireless network. This then allows the wireless stations to exchange configuration information while they are operating in a low-power mode (e.g. in a mode where the network stack is disabled).
