Abstract: A portion of a logical block address to physical block address (“L2P”) translation map may be identified. A last snapshot of the portion of the L2P translation map may be identified. One or more write operations may be determined, where the write operations are associated with logical block addresses of the portion of the L2P translation map. The write operations may have been performed after the last snapshot of the portion of the L2P translation map was stored. An address on the portion of the L2P translation map may be updated by a processing device based on the determined one or more write operations and the last snapshot of the portion of the L2P translation map.

Abstract: A computer system which includes one or more wireless interface devices that are adapted to communicate with a remote host over a radio link. Each of the wireless interface devices is a pen-based device which includes an ink field in which pen events are translated into pen data packets and transmitted to the remote host over the radio link. Local inking is provided at the wireless interface device in order to maintain the pen paradigm in essentially real time.

Abstract: A pen-based portable computer system, and more particularly, to a computer system which includes a host computer or a server that is adapted to interface with one or more wireless interface devices over a radio link. The wireless interface devices are pen-based devices which include a digitizer panel and are adapted to operate on a mouse mode, as well as a pen mode. In a mouse mode, pen down events are translated into mouse data and transmitted over the radio link to the remote server or host computer. In a pen mode, pen down events in an ink field are formulated as pen data. In accordance with an important aspect of the present invention, the wireless interface device includes a local handwriting recognition system for translating handwriting into characters which are then transmitted to the remote server or host computer over a radio link for processing.

Abstract: Systems, methods, and software that update or recover system firmware (BIOS) of a computer system using a utility running from a protected area of a mass storage device. This avoids the standard operating system environment and removes the possibility of tampering or deletion of required files. Files containing a copy of system firmware (BIOS) and a firmware update utility for writing to the system EEPROM or flash ROM are transferred to the mass storage device. Once the files are transferred, the area on the mass storage device containing these files are protected in a Host Protected Area, for example. After protecting or locking this area of the mass storage device, the system firmware or boot utility either boots the standard operating system or runs the firmware update utility from the Host Protected Area in recovery mode if the firmware is corrupted. This allows the firmware update utility to run in an environment outside of and independent of the standard operating environment of the computer system.

Abstract: A system for compressing program files at a remote host computer and transmitting the compressed program files to one or more wireless interface devices using a wireless link. The received compressed files are stored in an electronically programmable storage device on the wireless interface device. The remote host includes a CPU, a storage device for running and storing one or more programs and a wireless link for communicating with the wireless interface device. The wireless interface device is able to control and access the one or more programs on the remote host using the wireless link.
