Filed:

Feb 3, 2005

Appl. No.:

11/050286

Inventors:

David K. Mathews - Fort Worth TX, US

Assignee:

RadioShack, Corp. - Fort Worth TX

International Classification:

H04B 1/03

US Classification:

455557, 455 661, 455344, 369 2, 700 94

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 incorporates a spindle driven sensor means to control power and function selection within the device.

Appl. No.:

10/925467

Inventors:

David K. Mathews - Fort Worth TX, US
Alfred C. Griffin - Hillsboro TX, US

Assignee:

RadioShack Corporation - Fort Worth TX

International Classification:

F21V 17/00

US Classification:

362441, 362433, 362444, 362378

Abstract:

A data receiving or transmitting device, having data receiving or transmitting capability, is coupled respectively from or to an AC power line through a standard light bulb socket. In one aspect, a data interface includes a data receiving device that may be configured for extracting data encoded for transmission or encoding data to be embedded and transmitted along the AC power line branch circuit. In another aspect a data receiving device includes a loudspeaker, an amplifier, and a data decoder coupled to the AC power line for playback of audio program material communicated to the device along the power line. The device screws into a light bulb socket for a “no-tools” installation.

International Classification:

G06F 3/00

US Classification:

715747, 715719, 715738, 715745

Abstract:

An apparatus and method for obtaining preferred information from a network by execution of a sequence of actions in response to a single actuation in a network terminal device. A sequence of actions is programmed in network terminal device. The sequence of actions are executed in response to a single actuation if a softkey. A network destination parameter and a user preference parameter are also programmed. The sequence of actions includes coupling a destination parameter into the network, upon receipt of a network reply message corresponding to said destination parameter, coupling a preference parameter into the network, and upon receipt of the preferred information from the network, outputting the preferred information from the network terminal device.

Abstract:

There is disclosed a data receiving device for coupling to an AC power line through a standard light bulb socket. A standard medium lamp base is supported by a frame and connected to a branch circuit of the AC power line. An electrical device having signal terminals and supported by the frame is driven by electrical circuitry having a first input and a first output. The first output is coupled to the signal terminals for driving the electrical device. A data receiver has a second input for receiving both AC power and a data signal from the AC power line. The second input is coupled to the lamp base and a second output is coupled to the first input of the electrical circuitry. In another aspect, a data interface comprising a standard medium lamp base coupled to a data terminal device having a data receiving and/or transmitting interface circuit therein is threadably engaged to a standard medium lamp receptacle connected to the AC power line branch circuit. The data receiving and/or transmitting interface circuit, or data modem, in the data terminal device is configured for extracting data encoded for transmission or encoding data to be embedded and transmitted along the AC power line branch circuit.
