Abstract: A rivet-type flapper valve assembly for a fluid device has a main body part defining a valve orifice communicating with the fluid device. The main body part includes a pin or shaft of a rivet spaced adjacent to the valve orifice. The main body part is permanently attached to the fluid device, such as by brazing. A flapper valve is then mounted on the rivet shaft to cover the valve orifice, and the rivet shaft is deformed to retain the flapper valve in place.

Also, a handheld electronic device that includes an input apparatus having a plurality of input elements, a processor, and a memory in electronic communication with the processor. The memory stores one or more routines executable by the processor for implementing the method described above.

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: A system and methods for coordinating the operation of a client security module and a host security module on a mobile electronic device. The modules communicate with each other through a platform abstraction layer using application programming interfaces to coordinate their activities. In particular, on start-up of the device, the host security module obtains user authorization input from a user and passes the input to a client operating system for validation. Once validated, the host security module unlocks the host-side of the device. At the same time, the client operating system sends a notice or request to the client-side virtual machine requesting that the client-side be unlocked. Once the virtual machine is initialized and available it launches the client security module and unlocks the client-side. During the delay while the virtual machine loads, the user is given access only to the host applications.

Abstract: A method of customizing the branding of utility software associated with a customized computer peripheral device. The customized peripheral device includes brand data stored in memory. The utility software includes a branding module that reads the brand data from the peripheral device during installation upon a computer and customizes the utility software based upon the brand data. The brand data may include the custom branding information or may provide a brand identifier that permits the branding module to obtain the correct custom branding information from a remote server.

Abstract: A reverse patch for undoing a forward patch for obtaining a new binary image from an old binary image is generated in two parts. First a reverse index file is generated when the forward patch is created at a host or server. The reverse index file identifies regions of similarity between the old binary image and the new binary image. The reverse index file is transmitted with the forward patch to an electronic device. Second, while applying the forward patch to obtain the new binary image from the old binary image, the electronic device generates the reverse patch based upon the new binary image, the old binary image, and the reverse index file. The forward patch and reverse patch may both be incremental patches. Incremental patches are generated and applied on a sector-by-sector basis.

Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.

Abstract: A method of rendering text on an output device using a pre-developed image of a custom font. An image file defines an image of a custom developed character set. The custom character set may be developed off-line using graphics development tools. Associated character information enables the location of specific characters within the image. When a text character is output to a display or other output device, a custom font module locates the text character within the image and defines a subimage that contains the text character. The subimage is rendered upon the output device, thereby producing an image of the text character.

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 system for repairing embedded memories on an integrated circuit includes an external Built-In Self-repair Register (BISR) associated with every reparable memory. Each BISR is serially configured in a daisy chain with a fuse box controller. The controller determines the daisy chain length upon power up. The controller may perform a corresponding number of shift operations to move repair data between BISRs and a fuse box. Memories can have a parallel or serial repair interface. The BISRs may have a repair analysis facility into which fuse data may be dumped and uploaded to the fuse box or downloaded to repair the memory. Pre-designed circuit blocks provide daisy chain inputs and access ports to effect the system or to bypass the circuit block.

Abstract: A method for automatically configuring an access control point based upon the network resource requirements of an application. The installation of a new application on a mobile device or other user device is accompanied, before, during, or after installation, with the distribution of access control information. An access control point blocks communications based upon access rules. An access update module modifies or sets the access rules based upon the access control information. The access control point and the access update module may be located within the mobile device, within an associated wireless connector system, or in other locations within the mobile communication system. The setting or resetting of the access rules based upon the access control information may be triggered during installation, modification, or removal of the application.

Abstract: A method and mobile device that self-terminates a media service if an out-of-coverage condition is detected. 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. The loss of coverage by the remote mobile device may be detected by observing whether the remote mobile device has failed to send any data packets for more than a predetermined period of time. If an out-of-coverage situation is detected, then the method or device initiates service cancellation or release.
