  • Remote Control Multimedia Content Listing System
    Publication number: 20080036642
    Abstract: A remote control multimedia content listing system for providing an updated content listing of various media within a remote control. The remote control multimedia content listing system includes a remote control having a housing, a display, a keypad, and an electronic system for receiving configuration data from a control station via a global computer network (e.g. Internet). The user may enter media information into the electronic system thereafter uploading the media information to the control station. The control station analyzes the uploaded media information and transmits the appropriate configuration data to properly configure the electronic system to provide a usable “guide” for the media. The user may also access a web site of the control station and manually enter the media information after which the control station sends the appropriate configuration data to the electronic system.

  • Keyboard with integrated laptop stand
    Patent number: 7327560
    Abstract: A full-size keyboard with an integrated laptop stand. In one embodiment, the laptop stand is part of a cover for a portable keyboard, with the cover unfolding and including a pop-up stand for supporting a portable computer. The stand is thus connected to the keyboard rather than being a separate article. The cover includes electronics, such as a USB hub and ports, an MP3 player docking station, speakers, etc. A flexible hinge connects the keyboard and cover, with imbedded electrical flex connectors. A presence sensor, such as a PIR sensor, shuts off battery use by these electronics when the user is not around.

  • Wireless Peripheral Interface with Universal Serial Bus Port
    Publication number: 20080022031
    Abstract: A wireless peripheral interface is used for coupling with a Universal Serial Bus (USB) port for connecting a wireless peripheral with a host computer or controller. Wireless peripheral devices (e.g., keyboard, mouse, trackball, touch pad, joysticks, and game controllers) transmit communication signals, e.g., radio frequency (RF) signals, to the peripheral interface, which are received and processed into formats suitable for transmission to the host computer or controller via USB, either alone or in combination with other standard external bus systems, such as serial and PS/2.

  • Universal charger
    Publication number: 20080007212
    Abstract: A universal charger which can charge multiple electronic devices, such as a keyboard, mouse, remote control, etc. In one embodiment, a user is directed to a website over the internet to a site containing charging profiles for multiple devices. The user selects the particular devices the user will want to charge and downloads the charging profiles. The charging profiles are provided to the universal charger device. A number of mechanisms are provided to identify the device, such as wireless or wired communication with the device or reading an RFID tag in the device. Various embodiments are disclosed, including having smaller devices (remote control, mouse) moved to the charger and the charger move to larger devices (keyboard). Also, various indicators are shown to indicate which device needs charging, and various lighting schemes show the amount of charging.

  • VIDEO GAME CONTROLLER WITH COMPACT AND EFFICIENT FORCE FEEDBACK MECHANISM
    Publication number: 20080004114
    Abstract: A compact game controller incorporates an efficient and compact force feedback mechanism. Forces are generated at one of the controls of the controller in reaction to an action in a video game. The type of controller that can be held with two hands is limited in terms of size and internal space and in wireless versions is limited in terms of battery power. Efficient power consumption in the controller enables considerable usage time between battery replacement or recharging in wireless versions. The force feedback mechanism incorporates a double reduction gear system with a unique geometry which enables usage of a compact and energy efficient motor. The efficient force feedback mechanism and assembly can therefore be packaged within a compact ergonomic controller.

  • Non Impact Video Game Controller for Dancing Games
    Publication number: 20080004111
    Abstract: A video game controller for home video game systems is situated between a player's feet and is used to detect positions outside the footprint of the controller. The controller transmits the position data to the video game system and enables game play. In dance games, the controller detects dance steps when the player dances around the controller. A signal is transmitted from locations at the perimeter of the controller, reflected by the player's foot, and then received back at the controller. In a preferred embodiment the location is detected as a function of the time the signal is transmitted/received and by the matrix of signals received. Modulation of the transmission and reception minimizes detection of noise and distant reflections and therefore minimizes or eliminates false position detection.

  • System and method for transmitting bidirectional signals over a cable antenna
    Patent number: 7313640
    Abstract: A method and system for data wireless systems on computers, for using the same cable to bi-directionally transmit antenna signals as well as other signals to and from the inside of a shielded computer housing. An example of a control signal is a connect signal for establishing initial contact between the computer and a remote wireless device. An example of a control signal transmitted from inside the computer housing to the outside, is a signal for lighting an LED. Antenna signals are separated from the control signals based on differences between these signals, for example, differences in frequency. In one embodiment, a capacitor filters out a DC control switch signal, while the high frequency antenna signal is filtered by the normal input pin circuitry of a processor.
