Abstract: An integrated home entertainment unit includes a print media source, a print engine coupled to the print media source configured to hold a print medium, an optical disk drive configured to output formatted digital data, and a controller. The controller has a processor and a decoder, and controller being communicatively coupled to the optical disk drive and to the print engine. The decoder is configured to decode the formatted digital data to produce output data. The processor executes instructions to control the print engine to print an image on the print medium supplied from the print media source using at least a part of the output data. A housing has mounted therein the print media source, the print engine, the optical disk drive, and the controller.

Abstract: An apparatus for connecting a printer to a cellular radio system. The adapter allows the printer to conduct facsimile operations. The adapter has a facsimile module which includes executable instructions for decoding fax data and processing the fax data to generate print data for printing; a cell radio; one or more communication ports having at least one of the communication ports in communication with the printer; and a data encoder in communication with the facsimile module and the cell radio. The data encoder is configured to convert data transmitted between the facsimile module and the cell radio.

Abstract: A pressure sensitive touch pad and an overlay depicting a pattern, e.g., a typewriter keyboard, for providing specific data characteristics of the pattern to a host computer and to a specific application program of any one of a number of application programs resident in the host computer, which specific application program includes software programmed to accept configured touch pad output signals from the touch pad corresponding to the pattern, which output signals are a function of originally generated touch signals achieved by actuation, normally by touch, of the pressure sensitive overlay surface at any particular point on the pattern, which pattern on the overlay on the touch pad corresponds to and is coordinated with a specific application program in the host computer including a multitude of application programs.

Abstract: A computer system, and particularly a handheld mobile client system, in which an energy management control program having a plurality of cooperating components permits a designer to choose from among a plurality of foci for energy management.

Abstract: A computer system comprising a central processing unit (CPU) configured to accept coordinate type data from a touchpad or the like. The CPU has an operating system executing thereon with special support for interfacing to the touchpad. The operating system has the following capabilities: (1) mapping out geometric regions of the touchpad and assign the regions to specific region identifiers responsive to application programs and (2) determining the region identifier of a touched region and passing that region identifier to the application program. Support is also provided for changing the units of the commands used to define the regions.

Abstract: A method of saving and restoring the state of a CPU operating code in protected mode on a computer system. The save method makes use of BIOS operating in shadow RAM located in a region where linear addresses equal physical addresses while saving the state of the CPU. The registers that cannot be directly saved to memory are determined by searching the system memory for data structures that correspond to the particular register. The restore method uses dummy page tables that point to the shadowed BIOS to allow the CPU to reenter protected mode without generating a protection fault.

Abstract: A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems.

Abstract: A computer system having a suspend/resume capability in addition to the normal operating state and the off state. Closure events of single momentary pushbutton switch control changes between the normal operating state, the suspend state, and the off state, depending on the value of a flag. If the flag is set in a certain state, closure events of the switch cause the computer system to change back and forth between the normal operating state and the off state. If the flag is set in a different state, closure events of the switch cause the computer system to change back and forth between the normal operating state and the suspend state. The switch also controls the video subsystem of the computer system such that pressing the switch blanks the video display terminal giving the user instantaneous feedback of the switch press.

Abstract: A desktop computer system having the capability to suspend and resume the state of the computer system. The suspended system state is saved to the system hard file such that system power may be removed, effectively allowing a system suspend requiring no power from the power supply.
