摘要:
The application of external power to an external module connected to a portable information handling system enables the card detection signal to be asserted low, thereby allowing the personal digital assistant to detect and activate the external module. When external power is disconnected from the external module, the card detect signals turn off, thereby deactivating the external module and electrically disconnecting the external module from the personal digital assistant. Substantially all of the power for the external module is provided independently from the internal power supply of the portable information handling system.

A signal from a remote control is used to operate a device having a built-in communication port and a built-in microprocessor, even though the port does not normally recognize the signal. Specifically, even if the port flags an error during decoding of information from the remote control signal, the microprocessor ignores the error and uses the decoded information in the normal manner. Therefore, the microprocessor recognizes a pattern formed at the communication port by a signal emitted by the remote control, e.g. to identify a button on the remote control that has been pressed. During the recognition process, the port flags one or more errors (such as framing error, parity error), and such errors are ignored by the microprocessor. Programming the microprocessor to ignore errors from the port allows the device to operate with signals in a format different from the format normally recognized by the port. When use of the remote control is completed, the device may be returned to normal operation, wherein erroneous information is rejected.

Methods and systems for display of information on an external display using a handheld computing device are provided. An expansion module is configured to attach to a handheld computing device such as a personal digital assistance (PDA). The expansion module includes a communication interface to operably connect the module to the computing device via a expansion slot. The module also includes a memory, and an external display controller. When the expansion module is connected to the computing device, the computing device detects the presence of the module. Control software is then executed by the computing system's microcontroller causing graphic control interfaces to be displayed on the computing system's display screen. A user using the control interfaces can operate the control software to cause the computing device display presentation data on the external display device.

A system and method for playing audio only in a disk player. The disc player is configured to read data from disks formatted according to a selected audio and video standard. The system includes a file reader to read files of audio and video files based on the audio and video standard. A stream parser identifies audio data, video data and sub-picture data. An audio decoder decodes the audio data according to the audio standard. A video stub receives the video data and leaves the video data unprocessed. A sub-picture menu processor extracts menu information. A user interface system to use the menu information to configure at least one user input to play audio-only from the disk according to the menu information.

When a document generated from an application is printed, each page of the document is treated as a separate image Then, one or more templates are generated for a document, with each template containing common elements for a set of images in the document. For each set of images, sets of changes are identified. The templates and corresponding sets of changes to each image in a set of images may be reduced from one color space to another color space. The reduced templates and corresponding sets of changes are then compressed and formatted into a native file transfer format understood by a mobile computing tool, for transfer to a mobile computing tool, where the data is decompressed and images are rebuilt from the templates and corresponding sets of changes.
