Patent Number Title Of Patent Date Issued
6317797 System for automatic synchronization of common file between portable computer and host computer November 13, 2001
A handheld computer which contains an LCD display having a digitizing surface to allow pen input. Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive. Several alternative communication paths are available, such as th
6058012 Apparatus, method and system for thermal management of an electronic system having semiconductor May 2, 2000
A thermal management controller to regulate the operating temperature of high speed, high circuit density semiconductor dice in an electronic product. The thermal management controller monitors the temperature of a heat sink in thermal contact with the high speed, high circuit density
5928329 System for automatic synchronization of common file between portable computer and host computer July 27, 1999
A handheld computer which contains an LCD display having a digitizing surface to allow pen input. Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive. Several alternative communication paths are available, such as th
5805882 Computer system and method for replacing obsolete or corrupt boot code contained within reprogra September 8, 1998
In accordance with the invention, a computer system is provided with a flash read-only-memory (ROM), a microcontroller and a data port. The microcontroller initially owns the flash ROM. The microcontroller further has a separate ROM upon which it can execute boot-up instructions. After
5729683 Programming memory devices through the parallel port of a computer system March 17, 1998
A controller circuit that controls the transfer of a computer operating system from a host computer into a hand-held computer system through the parallel port without the need of intervention from the microprocessor. The operating system is loaded into flash memory devices located in the
5666530 System for automatic synchronization of common file between portable computer and host computer September 9, 1997
A handheld computer which contains an LCD display having a digitizing surface to allow pen input. Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive. Several alternative communication paths are available, such as th
5542077 Personal computer with CMOS memory not having a separate battery July 30, 1996
A computer system which utilizes a CMOS memory/RTC and does not have a separate battery for powering the CMOS memory/RTC. A serial EEPROM is utilized to maintain the contents of the CMOS memory. When the computer is entered into a setup mode and the CMOS information is to be saved, it is
5534889 Circuit for controlling bias voltage used to regulate contrast in a display panel July 9, 1996
A liquid crystal display (LCD) panel which has its contrast controlled through the use of a pulse width modulation (PWM) circuit contained in the video controller and a contrast control circuit. In response to a particular video refresh mode, the PWM circuit modulates the pulse width
5455907 Buffering digitizer data in a first-in first-out memory October 3, 1995
A computer system with a digitizer based screen display in which the digitizer data is buffered through a first-in first-out memory (FIFO). The processor is only interrupted when a full digitizer data packet is available in the FIFO, rather than being interrupted on each data byte av
5446320 Circuit for clamping power output to ground while the computer is deactivated August 29, 1995
A circuit for connecting the power supply output of a computer to ground when the system is shut down to counter adverse effects of backfeed voltage which includes a MOSFET between the power supply output and ground. In one embodiment the MOSFET is switched on by a signal that deacti
5315228 Battery charge monitor and fuel gauge May 24, 1994
A battery charge controller and fuel gauge which accurately monitors the voltage, temperature, and charge and discharge current of a rechargeable battery, and calculates the battery's charge capacity and charge level. Each time the battery is fully discharged, any calculated charge level
5200689 Battery charge monitor to determine fast charge termination April 6, 1993
A battery charge controller and fuel gauge which accurately monitors the voltage, temperature, and charge and discharge current of a rechargeable battery, and calculates the battery's charge capacity and charge level. Each time the battery is fully discharged, any calculated charge level
4400778 Large-volume, high-speed data processor August 23, 1983
A data processing system having an architecture that will allow high-speed direct device-to-device data transfers without the necessity of first detouring the data through a computer memory. The system consists of a host computer and a remote signal processing subsystem connected thereto
