  • Patent number: 8320597
    Abstract: An accessory for a portable electronic device having a speaker uses an acoustic wave guide to passively amplify and direct the output of the device's speaker. The accessory has a housing with a docking cavity formed therein. The docking cavity has supportive sidewalls that are adapted to receive and support the portable electronic device in an upright position. A cable access channel is formed in the docking cavity that allows a connector and cable to be coupled to the portable electronic device when the portable electronic device is mounted in the docking cavity. An acoustic waveguide having a spiral shaped acoustic chamber is positioned in the housing such that an entrance to the acoustic waveguide corresponds to a hole in the docking cavity that is positioned to correspond to the location of the speaker of the device when the device is mounted in the docking chamber. The exit of the acoustic chamber corresponds to an exterior opening in a sidewall of the housing and the hole in the docking cavity.

  • Patent number: 8306476
    Abstract: A transmitting accessory couples with a portable electronic device such that audio signals or data from the device can be digitally transmitted to a remote receiver. The accessory includes an input port for receiving audio data from the portable electronic device. A digital transmitter transmits digital data corresponding to the audio signals or data from the portable electronic device to the remote digital receiver. If the audio signal is an analog signal, the accessory uses encoding circuitry to digitally encode the analog audio signal for transmission. The audio signal may be encoded into an HD radio format for reception by an HD radio receiver. The user inputs of the portable electronic device can preferably be used to control functions of the accessory and the device's display to display the selected transmission frequency or channel.

  • Patent number: 8054042
    Abstract: A modular power supply that can be adapted to receive and charge practically any type or number of portable electronic devices includes a power converter that receives an AC wall voltage and converts the wall voltage to DC bus voltage. Each charging module has a pair of conductive rails and magnets positioned around the exterior of the module. The power converter has a connector that is physically and electrically coupled to a charging module through a pair of magnets and conductive rails such that the DC bus voltage is applied to the conductive rails of the module. Each charging module has a dock that physically couples to a portable electronic device and supplies a charging voltage produced from the DC bus voltage to the device. Additional charging modules can be physically and electrically coupled together by simply placing the modules adjacent one another through the interaction of the module's conductive rails and magnets.

  • Patent number: 8000820
    Abstract: A transmitting accessory includes a base dock for receiving a portable electronic device and a transmitter that is removably coupled to the dock. When the device and transmitter are mounted on the dock, the transmitter receives signals from the device through the dock and transmits the signals to a remote receiver. The transmitter can be decoupled from the dock and coupled directly to the portable electronic device when the device is removed from the dock such that the device and transmitter can be carried and function as a single unit. The user inputs of the portable electronic device can preferably be used to control functions of the accessory and the device's display to display the selected transmission frequency or channel of the transmitter.

  • Patent number: 7925039
    Abstract: A cylindrical controller provides a user interface for an electronic device that is easier to use than conventional controls. The cylindrical body contains a number of sensors that detect when the cylindrical body is rotated between the thumb and finger of a user. The sensors determine whether the rotation is in a clockwise or counter clockwise direction. The present invention allows users to remotely control a consumer electronics device by manipulating a cylindrical body with familiar prehensile gestures, i.e., pinching, squeezing, and rolling.

  • Patent number: 7808226
    Abstract: A method, device, and apparatus for tracing a conductive line and locating any concealed surveillance devices coupled to the line uses a signal generator to produce a test signal having a fundamental frequency which is coupled to the line under test. The test signal flowing through the line under test creates electromagnetic waves that propagate through the atmosphere away from the line. A portable locator probe is used to detect the radiated signal and thus the conductive line by detecting the magnitude of the radiated signal. As the locator probe is moved closer to the line, the amplitude of the detected signal increases. In addition, the portable locator probe detects harmonic signals radiated from nonlinear junctions coupled to the line at harmonic frequencies of the fundamental test signal.

  • Patent number: 7743999
    Abstract: A case for portable electronic device has a set of substantially rigid opposing faces mounted on a hinge that fold together to enclose the device. An internal electrical connection between the device and the case is used to provide an electrical access point on the exterior of the case. The external electrical connection is accomplished through a passive electrical connector positioned on the hinge that holds the opposing faces together. Additional active electronics and batteries may also be positioned in the hinge such that the case can be operationally linked with the device contained in the case. Since many portable electronic devices are dimensioned to be carried in pockets or purses, limiting the size of a protective carrying case can be crucial to gaining consumer acceptance. The case is particularly well adapted for use with a digital music player.

  • Patent number: 7697627
    Abstract: A rotary encoder is used to select a transmission frequency for an FM transmitter associated with a portable electronic device such as a cellular telephone, MP3 player or other portable type electronic device. The rotary encoder is turned in a clockwise or counterclockwise direction to raise or lower the transmission frequency of the FM transmitter. Movement of the rotary encoder is translated into a frequency change on a linear, circular or exponential basis by a microprocessor. The transmission frequency of the FM transmitter is then altered to the selected frequency and the selected frequency is displayed on an LCD screen of the portable electronic device. The rotary encoder may also be used in connection with an accessory for a portable electronic device.
