  • Patent number: 10236990
    Abstract: A device including a remote control of remote operation of the device is described. The remote control includes a key matrix and a microprocessor. The microprocessor processes key scan codes from the key matrix and converts the key scan codes to amplitude modulated remote control commands for transmission by a wireless transmitter. The device includes components so that a user can operate the device locally without a remote control. The components in the device that enable local operation of the device are comparable to components in the remote control that enable remote operation of the device so that a minimum of changes are required in the device to enable local operation of the device.

  • Patent number: 9736964
    Abstract: An electronic device includes a cover for one or more heat generating components, with the cover providing at least a combined conductive, convective, and radiant cooling for the heat generating components while maintaining the device within a prescribed temperature range. Conductive cooling is realized by providing thermal coupling between each of two or more depression regions in the cover and one or more heat generating components. Appropriate placement of air inlets and outlets through the cover provides convective cooling of the heat generating components and the thermally coupled depression regions. Heat from the heat generating components thermally coupled to one depression region is effectively isolated from heat generated by other heat generating components thermally coupled to another adjacent depression region at least in part via the air outlets through an interior region between the two adjacent depression regions.

  • Patent number: 7594638
    Abstract: An auto-eject foot stand assembly with multi-viewing angles for a visual device includes a foot having an axle perpendicular to the foot. The axle rotatably extends in a bracket. A gear is securely provided outside the axle and between the bracket and the foot. A spring is provided between the gear and the bracket. An elasticity plate is engaged with the gear. A locker is pivotally mounted on the bracket and operated by a metal spring plate to lock the gear. When the metal spring plate is pressed, the gear is released from the locker and the foot can be ejected under the elastic force of the spring. By the engagement between the gear and elasticity plate, the foot can be rotated and positioned at various desired viewing angels.

  • Publication number: 20090096924
    Abstract: The disclosed embodiments relate to a low cost signal adjustment or calibration method and apparatus for generating a stable clock signal that is used to drive a communications interface (e.g., a UART port). More specifically, a processor within a microcontroller uses a low frequency crystal oscillator and a scaling module to remove a frequency offset error contained in an unstable clock signal generated by a high frequency RC oscillator. The processor detects and removes the frequency offset error when specific triggering events occur such as when the microcontroller is powered up, awaken from a sleep or stand by mode, or experiences a communications error.

  • Patent number: 7471988
    Abstract: A digital audio player and a method for processing encoded digital audio data, wherein the digital audio data is encoded using one of a plurality of encoding formats. The exemplary audio data player includes a hard disk or other data storage medium for storing data files, a microcontroller, buffer memory for anti-skip protection, and an audio decoder. The encoded audio data files and associated decoder files are downloaded from a personal computer or similar device to the audio data player hard drive. The player provides a menu-driven user interface for selection, sorting, and playback of stored audio data files. The audio decoder, generally a digital signal processor, provides various preset equalization modes. The preset modes are specific to audio genres such as jazz, pop, and rock.
