Abstract: A two-way wireless communication system comprises a central authority in communication with a plurality of client devices via both a circuit switched data communication system and a packet switched data communication system. The packet switched communication system can assign packet switched network addresses to the client devices dynamically.

Abstract: A two-way wireless communication system comprises a central authority in communication with a plurality of client devices via both a circuit switched data communication system and a packet switched data communication system. The packet switched communication system can assign packet switched network addresses to the client devices dynamically. Therefore, the central authority can be configured to send a circuit switched message, through the circuit switched data network, to a client device requesting the client device to register with the central authority through the packet switched data network.

Abstract: A USB chip having a self-calibration circuit is provided. The USB chip includes a comparing circuit, a digital circuit and an adjustable current output device. A close-loop structure is provided to monitor an output voltage level of the USB chip and then an output current is dynamically adjusted to calibrate the output voltage level.

Abstract: A mobile data device includes a database of identifiers and an authorization module. The identifiers are associated with one or more communication devices in which the mobile data device may be interfaced. The authorization module determines if the identifier of communication device is within the database and facilitates network access to the communication device if it is included.

Abstract: A multiple network interface system that efficiently utilizes the different interfaces by binding specific applications to them. The system is able to direct selected applications to specified interfaces through a resource management module, which can dynamically or manually bind the application. The resource management module acts as a router within the system, encompassing all the interface connections.

Abstract: A delay control circuit includes a first delay unit, a signal regulation unit, a selector and a second delay unit. The first delay unit is used for delaying an input signal and generates a delayed input signal. The signal regulation unit is coupled to the first delay unit and outputs a rising edge delay signal and a falling edge delay signal according to the input signal and the delayed input signal. The selector is coupled with the signal regulation unit and outputs one of rising edge delay signal and falling edge delay signal according to the control signal. The second delay unit is coupled to the selector for delaying the output of the selector and outputting an output signal.

Abstract: A wireless communication method includes monitoring WWAN signals for a device while a primary processor of the device is in a low-power or power-off mode, determining if a WWAN signal includes a message including instructions to wake up the device, and transmitting a signal to the primary processor to wake up the device if the message includes said instructions to wake up the device.

Abstract: A system and method for custom branding a host application executed on a host device. The host device couples with an accessory device, where a host application is provided for managing/controlling the accessory device. During run time, i.e., when the accessory device is coupled with the host device, the host device can retrieve at least one resource object in which graphical user interface elements associated with the accessory device type have been encoded or preconfigured. The host device can then render the host application with the graphical user interface elements, effectively custom branding the host application.

Abstract: Systems and methods for detecting and removing metadata and hidden information from a file. A system can include a review module to identify metadata and hidden information, and a scrubber module for removing the metadata and hidden information from the file. The scrubber module can remove the metadata and hidden information automatically or upon prompting the user. The file can be a file attached to an electronic mail. The file can also be a file uploaded to a server.

Abstract: A computer system includes an application programmed to create a document, and a component including at least one internal module programmed to examine and modify the document to remove hidden information or metadata. The computer system also includes a communications interface for an external module programmed to examine and modify the document. The communications interface is programmed to allow the component to communicate with the external module.
