Abstract: A heat exchanger suitable for a vehicle includes a plurality of tubular first members arranged in a row and forming elongate gaps. These members form passageways for flow of a first fluid for heat exchange with cooling air flowing through the gaps. The first members and gaps form a primary heat exchange area. Inlet and outlet manifolds are connected to the first members for directing the first fluid through the first members. An associated cooling device circulates liquid coolant and comprises flat tube-like second members, each extending into a respective gap in a secondary area which is part of the primary area but smaller. The second members each have a thickness at least the width of their respective gaps. At least some of the first members can be formed with cut-outs in opposite flat sides, these cut-outs being sealingly closed by the second members.

Abstract: Execution of the ECMQV key agreement algorithm requires determination of an implicit signature, which determination involves arithmetic operations. Some of the arithmetic operations employ a long-term cryptographic key. It is the execution of these arithmetic operations that can make the execution of the ECMQV key agreement algorithm vulnerable to a power analysis attack. In particular, an attacker using a power analysis attack may determine the long-term cryptographic key. By modifying the sequence of operations involved in the determination of the implicit signature and the inputs to those operations, power analysis attacks may no longer be applied to determine the long-term cryptographic key.

Abstract: A method for handling open and close events in a wireless device is provided. The wireless device has a sensor coupled to a processor, the sensor providing an open signal to the processor indicating an open event when the wireless device is opened and providing a close signal to the processor indicating a close event when the wireless device is closed. The method comprises detecting one of the open event and the close event each time the open event or the close event occurs; recording the detected event and a time of the detected event with each event occurrence; monitoring for two recorded events within a predetermined time threshold; executing a first configured action if two events are recorded within the predetermined time threshold; monitoring for only a single recorded event within the predetermined time threshold; and executing a second configured action if only a single event is recorded within the predetermined time threshold.

Abstract: An e-mail distribution server may manage many pull e-mail accounts by periodically, as defined by an interval time, polling associated pull e-mail servers for new mail. If the e-mail distribution server receives an e-mail message destined for a recipient having a pull e-mail account managed by the e-mail distribution server, the e-mail distribution server may recognize an opportunity to poll the pull e-mail server associated with the pull e-mail account sooner than the expiration of the interval time.

Abstract: Each memory cell string in a generic NAND flash cell block connects to a Common Source Line (CLS). A value for applying to the CSL is centrally generated and distributed to a local switch logic unit corresponding to each NAND flash cell block. For source-line page programming, the distribution line may be called a Global Common Source Line (GCSL). In an array of NAND flash cell blocks, only one NAND flash cell block is selected at a time for programming. To reduce power consumption, only the selected NAND flash cell block receives a value on the CSL that is indicative of the value on the GCSL. Additionally, the CSLs of non-selected NAND flash cell blocks may be disabled through an active connection to ground.

Abstract: A device and method for scheduling follow-up events in relation to an existing event record. The device receives an input follow-up request associated with the existing event record and automatically generates a follow-up event record having information in its field populated using the information contained in the existing event record. The date of the follow-up event is automatically generated based upon the date of the existing event record. If the existing event record is a recurring event, then the date of the follow-up event is based on the frequency of recurrence. The follow-up event record may be displayed for user editing and may be transmitted to the attendees to propose scheduling of the follow-up event.

Abstract: A method and system that employs a proxy server associated with a mobile device in a wireless network, wherein the proxy server monitors whether the mobile device is still in coverage. The media service operates on top of a connectionless peer-to-peer packet-based transport protocol. The out-of-coverage condition may relate to the mobile device itself or to a remote mobile device engaged in the media service. If the proxy server detects that the device has lost coverage for more than a predetermined length of time, then it sends an out-of-coverage message to the other termination point engaged in the media service. If an out-of-coverage situation is detected, then the method or device initiates service cancellation or release. The out-of-coverage message may instruct the termination point to release or cancel the service.
