Abstract: An improved bias generator incorporates a reference voltage and/or a reference current into the generation of bias voltages. In some cases, the output of a biased delay element has a constant voltage swing. A delay line of such constant output voltage swing delay elements may be shown to provide reduced power consumption compared to some known self-biased delay lines. Furthermore, in other cases, providing the reference current to a novel bias generator allows a delay line of delay elements biased by such a novel bias generator to show reduced sensitivity to operating conditions, reduced sensitivity to variation in process parameters and improved signal quality, thereby providing more robust operation.

Abstract: An arrangement of memory devices and a controller is based on an interface with a reduced pin count relative to a known memory device and controller arrangement. Facilitating the reduced pin count interface are some operations performed by the controller. The controller determines a width for a Data bus while assigning a target device address to each of the memory devices.

Abstract: A mobile device, through the use of an NFC subsystem, may determine holster-proximity information, i.e., whether the mobile device is near to (including in) a holster or out of, and away from, the holster. The holster-proximity information may be used by the mobile device to enter into a user-inactive mode. Such entry into a user-inactive mode may involve disabling user interface components, such as input devices and output devices. In particular, the holster-proximity information may be used by the mobile device to disable the keyboard, that is, prevent presses on keys in the keyboard from being recorded. Such disabling may be considered of particular importance when the mobile device is going into and coming out of the holster.

Abstract: A mobile wireless communication device also has at least one wired communication port. Enhanced security is achieved by permitting the device to automatically disable one or more wireless ports when connected to a wired port. Specific combinations/permutations of such automatic control may be effected by use of an IT Policy also resident on the device.

Abstract: Call initiation on a device with potential for a large number of stored telephone numbers is simplified through the use of an integrated field for entry of an ambiguous filter string. As it is not clear, a priori, whether the user is manually specifying, in the integrated field, a telephone number or providing a filter string for filtering contacts, filtering is performed based on at least one filter string. Among the contacts that are part of a filtering result list, a default contact is selected for quick access.

Abstract: Communications between a computing device and a smart card reader configured for communication with a smart card are facilitated through the use, by the computing device, of a smart card resource manager and a smart card reader service. The smart card reader service acts as a relay for commands between the smart card resource manager and the smart card reader. Appropriate configuration of the smart card reader service obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the smart card reader. However, upon re-establishing a previously lost connection to a smart card reader and determining that a communication link between a smart card and the smart card reader has been ended and reestablished during the loss of connection, the smart card reader service may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.

Abstract: Based on bounds of a period of reduced operation for a base device, a base device generates a power management message for transmission to a peripheral device. In the power management message, the base device inserts bounds of a period of reduced operation for the peripheral device. As a result, the periods of reduced operation conserve battery power in both devices and the two devices may reestablish a communications channel upon reaching the end of the period of reduced operation and resuming normal operations.

Abstract: A method for notifying a client device of termination of at least one service provided to the client device by a server system within an enterprise network is disclosed. The method includes the step of establishing authentication data and notification data, where the authentication data is related to the notification data, and sending the authentication data to the client device for storage during a provisioning operation. When the server system identifies a termination of service, it sends the notification data to the client device, which may then authenticate the received notification data using the authentication data.

Abstract: Embodiments of a system and method for displaying a geographic location associated with an incoming call being received on a mobile device are provided. The mobile device has a user interface that provides a call screen to the user for identifying a phone number associated with the incoming call, and for displaying data including the geographic location associated with the incoming call. The geographic location is resolved by identifying a geographic location associated with a contact entry in the address book of the mobile device, or by comparing the area code of the phone number of the incoming call in a list of area codes and associated geographic location to find a match corresponding to the area code of the incoming call.

Abstract: A device and method for placing the device in a locked state having an associated set of permitted tasks so as to permit the device owner to share the device with others but maintain security over aspects of the device. A task change request is evaluated to determine whether the requested task is permitted and, if so, the requested task is allowed; if not, then an authorization process is invoked to prompt the user to input authorization data. Upon verification of the authorization data, the device may be unlocked and the requested change implemented. The permitted tasks may designate specific applications, specific operations or functions within applications or at the operating system level, one or more currently open windows, and other levels of granularity.

Abstract: A valve apparatus can be used to select between a cold or a hot coolant for heat exchange, this selection depending on whether an attached heat exchanger is to operate as a cooler or a heater. The apparatus includes a valve housing with first and second chambers formed therein, first inlet and outlet ports for flow of a primary liquid into and out of the first chamber and further ports for flow of coolant at different temperatures through the second chamber. A linear actuator in the housing has a body containing wax and a plastic piston that is movable to an extended position by expansion of the wax. The actuator body is located in the first chamber so the temperature of the wax is dependent on the liquid's temperature in the first chamber. An end portion of the actuator adjacent to the second chamber is made of plastic. A valve mechanism for controlling coolant flow is operably connected to the piston and located in the second chamber. This mechanism includes a spool movable by the actuator.

Abstract: A thermal bypass valve for a heat exchanger circuit includes a valve housing forming a valve chamber including a bypass passage and ports for the flow of heat exchange fluid into and out of the valve chamber as well as a bypass port defined by a valve seat. Two axially aligned thermally sensitive actuators are mounted in the chamber, each with an actuator body and its own movable piston extendible from one end of the body. One of these pistons operably engages the actuatory body associated with the other piston. Each actuator body is normally movable in the chamber in response to extension of its piston. One of the actuators extends its piston at a higher temperature than the temperature required for the other actuator to extend its piston. A bypass valve member is mounted on one of the actuators and can be moved by either actuator from an open position to a closed position.

Abstract: A solenoid valve has a main body defining a gas inlet passage, a gas outlet passage, and a cavity; a core tube forming a closure for said cavity so as to prevent an escape of gas; a cylindrical main piston slidably movable in said cavity of said main body, said main piston forming a front chamber and a back chamber in said main body, said main piston having a gas conduit for passing the gas from said gas inlet passage to said front chamber and an axial hole for passing the gas from said back chamber into said gas outlet passage with a bleed orifice at one end of said axial hole; said main piston being spring biased to a closed position; a spring biased pilot piston; and electrical coil means associated with said core tube to provide a magnetic field for movements of said pilot piston and said main piston, so that when said coil means is deenergized said pilot piston closes said outlet passage and causes a pressure equalization allowing said return spring to push said main piston to close the valve, while when
