Abstract: An e-mail filter may be associated with a schedule defining a recurrent active time period. As such, some e-mail filters may be active at specific times of day and on specific days of the week and inactive the rest of the time. Before applying any filters, the current time is determined and it is determined which filters are active. The determination of which filters are active is based on the current time being within the active time period.

Abstract: A portable electronic device includes a rendering circuit to visualize large format data files on a narrow display. The large format data files are rendered using either a desktop display mode or a mobile display mode. The desktop display mode renders the data file using data file-specified dimensions and resolutions. The data file is viewable in its entirety by automatic scrolling achieved by moving a cursor near the edge of the display. Data file elements may be edited while in desktop display mode. The mobile display mode renders the elements of the data file as a list with minimal regard for spatial orientation. Navigation in mobile display mode is field-to-field.
Abstract: A method and apparatus for estimating oscillator signal variation due to temperature and for providing an estimated frequency to a GPS receiver in order to assist the GPS receiver to acquire the signals quickly is disclosed. A temperature sensor is closely thermally coupled with the crystal oscillator in the GPS receiver and during GPS tracking mode, when the error in the oscillator signal is known with precision, outer bounds of TCXO frequency at given temperatures are maintained, which may correspond to rising and falling temperature conditions. During acquisition mode, an estimated frequency value is provided to the GPS receiver based on a determined average of these bounds. Optionally, an uncertainty factor associated with the frequency estimated may also be provided. The two bounds take into account the hysteresis effects of the oscillator signal drift due to temperature so that a more accurate initial frequency estimate can be provided to the GPS receiver, thus reducing its average time to first fix.

Abstract: For an Elliptic Curve Scalar Multiplication (ECSM) operation to be performed on a scalar and a base point, a given previous set of parameters that was used to split the scalar for a previous ECSM operation and a selected random integer are used to determine a new set of parameters for splitting the scalar. By basing the new set of parameters on the previous set of parameters, repeated use of the scalar to determine key-splitting parameters is avoided and susceptibility to a Differential Power Analysis Side Channel attack is minimized.
Abstract: Disclosed is a method of forming a heat exchanger turbulizer apparatus including a member having a longitudinal axis, a lateral width and a plurality of strips including first strips and second strips, each strip extending widthwise and being corrugated longitudinally so as to form a plurality of laterally spaced-apart sections connected to one another by bridges projecting from the sections in a common direction, the bridges of the first and second strips extending in the same direction and the corrugations of the second strips being offset laterally from the corrugations of the first strips. The method comprises: crimping longitudinally-corrugated strip material between first and second forming dies to form said apparatus, said dies being adapted such that substantially all lateral movement of strip material in crimping results from strip material being drawn laterally by material that has been displaced in a direction parallel to the direction of die movement.

Abstract: A wireless handheld device comprises a lower casing having a bottom end and a top end and a lid having a bottom end and a top end. The top end of the lid is rotatably coupled to the top end of the lower casing with at least one hinge component such that the handheld device is rotatable from a closed position to an open position and from an open position to a closed position. The lid and the lower casing have adjacent facing surfaces when in the closed position. When the wireless handheld device is in the closed position, at least the bottom end of the lid is displaceable relative to the lower casing generally in an axial direction of the hinge component such that the facing surfaces become misaligned for easy grasping of the lower casing and the lid.
Abstract: A user interface manager, interposed between a Windows service and user interface modules that communicate with the Windows service in distinct system status scenarios, can record interaction between the Windows service and each of the user interface modules. The recorded interaction, along with information collected from the user interface modules, can be used in conjunction so that user interaction with a first one of the user interface modules may continue with a second one of the user interface modules after a switch from one system status (e.g., logged on) to another system status (e.g., locked). Alternatively, responsive to the switch from one system status to another system status the user interface manager may simply stop the executing user interface module so that the interaction may be started over in the new system status.

Abstract: Distributed assembly of data packets into messages at a group of interface devices that receive data packets from within a coverage area. Each interface device in the group will take ownership of a sequence of data packets forming a message when a data packet of the message meeting predetermined criteria is received by that interface device. Once an interface device takes ownership of a sequence of data packets, it sends a request to the other interface devices for any missing data packets of the sequence that the ownership claiming interface does not have, and then assembles message upon receiving all the data packets of the sequence.
