  • Patent number: 7539219
    Abstract: A method and apparatus is provided for synchronizing both the initiation of playback of digital multimedia data in one or more receivers and the rate of playback of the digital multimedia data in the one or more receivers, all receiving the digital multimedia data from a single transmitter, without transmitting clock or timing signals to the receiver(s). An exemplary embodiment is described using the AC powerline as a medium of transmission, although the method and apparatus are adaptable to a variety of communication media.

  • Patent number: 7435141
    Abstract: Connector apparatus, and an associated method, by which to apply electrical power to a set of consumer electronic devices, such as a laptop computer and a mobile phone, or other portable device. The connector includes an input port to which a source of input power is applied, such as the electrical power provided by way of a power cable of the laptop computer, once suitably connected to a source of permanent electric power. The connector apparatus includes a set of output ports, a first port of which is connectable to the laptop computer and a second port of which is connectable to the other portable electronic device. A user of the consumer electronic devices is able thereby to power both of the devices with connection of only a single power cable to a permanent power supply source.

  • Patent number: 7266390
    Abstract: A network interface cassette for coupling signals between a wireless network and a tape head in a cassette tape player. The network interface cassette includes an enclosure that is conformed to the cassette tape form factor. It contains a transceiver that converts base band signals for radio frequency communications within the wireless network. It also contains a network controller that is coupled to communicate the base band signals with the transceiver. The network controller converts digital audio signals to and from the base band signals. There is an audio processor that converts the digital audio signals to analog audio signals. A coupling means converts the analog audio signals to magnetic audio signals. The coupling means is aligned to couple the magnetic audio signals to the tape head. A power supply with batteries and a generator driven from the cassette player capstan are provided. A wireless user interface adapter is provided to couple microphone and audio signals to the apparatus.

  • Patent number: 7130600
    Abstract: Apparatus, and an associated method, for facilitating personalization of a weather band radio that receives SAME messages broadcast by the NWR system. Alphanumeric indicators of locations are displayed upon a user display element. And, a listener of the radio enters, by way of a user input actuator, selection of selected geographical areas, identified by the alphanumeric indicators. The selected alphanumeric location is used to form a six-digit location code defined by the Federal Information Processing Standards (FIPS). And, the code so-formed is used by the weather band radio, selectably to alert weather anomalies broadcast by the NWR system within the selected geographical area of interest.

  • Patent number: 7101250
    Abstract: Provided is a transmitter that includes a channel selector for modifying an operating frequency of a radio-controlled toy. The transmitter has a channel selection switch that enables a user to pick a channel from a set of predefined channels. The selected channel is then transferred to the toy. For example, a microcontroller unit within the transmitter may be used to detect the selected channel. The toy is placed in contact with the transmitter and the transmitter's microcontroller unit communicates the channel to a microcontroller unit inside the toy. The toy's microcontroller stores the channel in a memory in the toy. The toy then tunes to the stored frequency to receive control signals from the transmitter.
