An embodiment provides a information handling device, including: one or more processors; one or more antennas, a communication element, and a memory device that stores instructions executed by the one or more processors, the instructions being executable by the one or more processors to: recognize a location within which the information handling device is operating through wireless communication received via the communication element; and modulate, based on which location the information handling device is operating within, a dynamic power reduction of transmission power through the antenna.

Controlling antenna output power

A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.

Display mode switching apparatus, method and program product

A computer and a method for enabling remote communication to a computer operating in a power-saving mode in which one or more one power sources to internal devices are disabled. The computer is equipped with a power management control circuit which is responsive to a first signal indicating that a device used to receive remote communication is to receive power while operating in a power-saving mode. In the event that a remote communications is detected which is targeted for the computer, a second signal is asserted by the remote communications device. The power management control circuit responds by exiting the power-saving mode and restoring power to the disabled power source to enable the computer to process the incoming communication. The remote communication may be through a wireless source such as a radio frequency channel or through a fixed wire such as a telephone network or LAN. Other aspects of the invention enable communication through an option card installed in a option slot or a notebooks docking station such as a radio device, modem, or LAN adapter.

Method and computer for remote communication while operating in a power-saving mode

A method that utilizes software and hardware mechanisms to meet the FCC requirement for a U-NII antenna to be an integral part of the device in which it operates, while providing wireless ready U-NII devices and CRUable U-NII radios. Enhancements are made to the software BIOS, including the inclusion of a table of approved radio-antenna PCI ID pairs to create an authentication scheme that verifies and authenticates the radio and antenna combination as being an FCC-approved unique coupling during boot-up of the system. The BIOS also comprises an OEM field that stores an encrypted secret key utilized to complete a second check of the radio model placed in the device. During boot up of the device, the PCI ID pairs from the BIOS are compared against the PCI ID of the radio and the secret key is checked against the radio model. Only a system with an approved combination of radio and antenna is allowed to complete the boot process, indicating an FCC approved device-antenna-radio combination under the 'integral' requirement.

A method and system are provided for detecting theft of a computer. A portable device is provided to wirelessly communicate with a theft deterrent function of the computer at a set frequency. In response to an increased distance between the portable device and the computer, a scan rate controller can automatically increase the scan rate for the wireless communication signal.

Theft deterrent system

A method that utilizes both software and combination software and hardware mechanisms to comply with the FCC requirement for an U-NII antenna to be an integral part of the device, while providing CRUable dual mode wireless cards and wireless-ready U-NII devices. Enhancements are made to the system BIOS and Device Driver, and two new software-implemented utilities are provided to create authentication schemes that verify and authenticates the CRUable dual mode U-NII radio and antenna combination as being an FCC approved unique coupling during operation of the system. The system boots with only ISM transmission capability and is allowed to complete a U-NII transmission request only with an approved U-NII radio-antenna combination.

A method that utilizes software means to meet the FCC requirement for an U-NII antenna to be an integral part of the device in which it operates, while providing wireless ready U-NII devices and CRUable U-NII radios. Enhancements are made to the system BIOS, including the inclusion of a table of PCI IDs and secret key pairs. The CRUable radio includes a pair of validation registers (VRs) and an EEPROM storing an PCI ID and secret key of an approved device. During boot up of the device, the PCI ID and secret key from the device's BIOS are compared against the PCI ID and secret key stored in the radio's EEPROM. The first comparison completes a radio-to-device authentication in the device, while the second comparison completes a device-to-radio authentication in the radio. U-NII transmission capability is enabled only when both parameters match, indicating FCC approved device-antenna-radio combination under the 'integral' requirement.

This invention relates to a video graphic control method and controller for sending to a display device graphic data from a processing device, and the object thereof is to provide a video graphic controller that increases the bandwidth available to a graphic engine or CPU without increasing power consumption or manufacturing costs, even when used with a conventional frame memory. A video graphic controller for controlling video data by storing the video data from a CPU 4 in a frame memory 18 and causing the frame memory 18 to output the data to a display device 30 uses a video data comparison means 20 to compare a piece of video data stored in the N-th address of the frame memory 18 to another piece of video data stored in the N-1-th address in order to determine whether the two pieces of data match, and if the two pieces of data match, outputs to the display device 30 the piece of video data stored in the N-1-th address instead of the piece of video data stored in the N-th address.

Method and apparatus for increasing video data bandwidth by comparing

Screen interpolation is done without using an expensive line buffer, etc., to enlarge and display an original image without incongruity. Rather than computing an interpolated pixel value as an average of adjacent pixel values and displaying the computed average pixel value in each frame, in accordance with this invention a pixel to be interpolated assumes one of the adjacent pixel values in each frame, but in successive frames assumes different adjacent pixel values in a mix such that the average value of the interpolated pixel over many frames becomes the desired interpolated value. Since successive frames are displayed very rapidly, to the human eye the afterglow (or visual persistence) phenomenon causes the screen to appear as if an enlarged image is being displayed at all times without incongruity (i.e., the varying values of the interpolated pixels are not noticed by the human eye).

Display of enlarged images as a sequence of different image frames which

Frame rate modulation is effected in which image data, which expresses a density of one dot by 4-bit dot data, is converted into a plurality of frame data, which express a density of one dot by 3 bits, so that the plurality of the frame data are sequentially displayed on the LCD. In the above conversion, the high order 3 bits of the dot data are extracted and made into data of one dot of each frame. In a case in which the least significant bit of the first dot data is 1 and the most significant bit is 0, 1 is added to a corresponding portion of the respective frame data. In a case in which the least significant bit of the dot data is 0 and the most significant bit is 1, 1 is subtracted from a corresponding portion of the respective frame data. In accordance with the above description, the image data is converted into the frame data as shown in Table 2, and the sum (apparent densities) of the plurality of converted frame data always changes in accordance with the changes in the dot data.
