Abstract: A method and apparatus for sharing information used to identify an object/person by a camera (e.g., a body-worn camera) is provided herein. During operation the apparatus will determine a set of characteristics that can be used to identify the object/person. The apparatus then analyzes the body-worn camera's FOV (or potential FOV) and removes characteristics from the set of characteristics to produce a minimal set of characteristics that can be used to identify the object/person in the body-worn cameras FOV. The minimal set of characteristics is then sent to the officer's body-worn camera for detection.

Abstract: The method shown in FIG. 4 continues with the iterative play cycles of the game, such as alternating moves between each player in the game. Player A operates a user interface on the game device 110A to select one of the content media items owned by Player A 236 to play during a move in the game (step 465). The user interface displays the selected content media item on the game device 110A which Player A operates (step 470) and sends a request to the game device 110B which Player B operates to reveal the selected content media item (step 475). The game device 110B which Player B operates receives the request (step 480) and reveals the selected content media item stored in the shared content media, such as in the shared content media items 238 shown in FIG. 2 (step 485).

Abstract: A method and system for limiting access to shared content media items stored in a device. The method establishes a connection with another device and initiates a session with the other device. The method synchronizes the device and the other device by receiving a copy of content media items stored on the other device, and storing the received copy of the content media items as shared content media items on the device. The synchronizing of the device and the other device may include transmitting a copy of content media items stored on the device to the other device. The method allows a user operating the device to access the content media items, but restricts access to the shared content media items based on the status of the session with the other device.

Abstract: The invention relates to a process for the production of chloramine comprising supplying a first reagent stream comprising chlorine gas and a second reagent stream comprising ammonia gas to a reaction zone maintained at a temperature of less than 275° C. and configured to allow expansion of the first and second reagent streams in the reaction zone to an extent sufficient to generate chloramine as a gas and ammonium chloride as a free falling solid. The invention also provides a chemical reactor suitable fur operating this process.

Abstract: The present invention concerns a catalytic composition comprising a catalyst effective for catalysing asymmetric hydrogenation reactions, which catalyst requires acid activation, an acidic material effective for activating the catalyst, and a buffering compound or composition capable of forming, in the presence of the acidic material, an acetal, a ketal, a hemiacetal, and/or a hemiketal. The invention also relates to an asymmetric hydrogenation process utilising such a catalytic composition, and to the use of such a catalytic composition for improving the enantiomeric excess of a desired asymmetrically hydrogenated product.

Abstract: A change in user interest level of a user application of a client device in communication with a network infrastructure at a first quality of service level is assessed (306). In response, the quality of service associated with the user application is dynamically changed (308) to a second quality of service level, while keeping the user application active, based, at least in part, on the change in user interest level of the user application.

Abstract: The present invention relates to a reactor comprising a plurality of reaction zones, a first reaction zone being configured to provide a first residence time for a reaction mixture passing therethrough at a particular flow rate, and a second reaction zone connected in series with the first reaction zone and configured to provide a second residence time for the reaction mixture passing therethrough at the particular flow rate, wherein the second residence time is at least about 1.5 times greater than the first residence time, the reactor further comprising means for bypassing at least one of the first and second reaction zones to reduce the effective residence time of the reaction mixture passing through the reactor.

Abstract: A method and a system for switching a mobile device (102) from a source Base Transceiver Station (BTS) to a target BTS in a mobile network (100) are disclosed. The method includes detecting an intention to switch the cell transmitted by the mobile device. A Base Station Controller (BSC) (112) then receives the switch detect time from the source BTS and/or the target BTS. The switch detect time is processed by the BSC to determine the switch time for the mobile device. The mobile device then switches from communication with the source BTS to communication with the target BTS, based on the switch time.

Abstract: Upon receiving (101) a vocoded voice frame and detecting (102) that the received vocoded voice frame comprises an erased frame, one automatically replaces (103) the erased frame with a valid frame having at least one error condition. In a preferred approach this error condition is one that is known to cause a receiving target platform to invoke a corresponding erasure process with respect to the valid frame when received.

Abstract: A communication system provides a clear channel link for transport of encrypted payload across a network of the communication system. When a source access network receives, via an air interface, a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header across the network, for example, to a destination access network. Based on the added header, the source and destination access networks are able to perform clear channel synchronization.
