Abstract: A mobile device is configured with electrical circuitry that causes the transmit channel electrical circuitry of the transmitter (Tx) of the mobile device to be electrically coupled to the receive channel electrical circuitry of the receiver (Rx) of the mobile device when one or more predetermined conditions occur. The electrical coupling of the transmit channel circuitry to the receive channel circuitry causes the Rx to be sufficiently damaged to render the mobile device nonoperational, thereby preventing further use of the mobile device. The one or more predetermined conditions correspond to conditions that indicate the mobile device has been lost or stolen and/or that an unauthorized user is attempting to use the mobile device in some manner.

Abstract: An electronically steerable antenna includes at least one driven element, at least one controllable counterpoise element, and a support structure on which the driven element and the controllable counterpoise element are disposed. The controllable counterpoise element has at least one geometric characteristic which can be varied. A radiating angle of the driven element is selectively controlled, at least in part, by modifying the geometric characteristic of the at least one controllable counterpoise element. The counterpoise element may include multiple conductive segments, at least a subset of which may be adapted to be individually electrically connected together so as to modify the radiating angle of the driven, element.

Abstract: A layer above the MAC and PHY layers of a wireless network employs a forward error correction (FEC) protocol extension with selective acknowledgement to reduce the likelihood of retries to enhance performance in, for example, home entertainment networking applications. In addition, certain system parameters of the wireless network are controlled so as to either i) align required bandwidth with particular sustainable channel parameters of the wireless network, or ii) modify the channel characteristics. One or more of three mitigation techniques might be employed with the FEC protocol extension to enhance maintenance of radio communication in the wireless network: Physical-layer Rate Adaptation, Dynamic Interference Avoidance, and Media-encoding Layer Adaptation.

Abstract: In a preferred embodiment, a battery charging system in the form of an integrated circuit (IC), incorporated in a consumer electronic device, has a charging controller, a charging current generator, a junction temperature sensor, and a device current monitor. The junction temperature sensor provides to the charging controller a measured junction temperature of the IC. The charging current generator utilizes fractional synthesis, which involves regulating the duty cycles of multiple current sources, to achieve increased current resolution. The charging controller regulates the charging current provided by the charging current generator based on the relation of the measured junction temperature to three or more threshold temperatures.

Abstract: In described embodiments, closed-loop mapping employs terrain and topology information when generating a closed-loop route given input route characteristics. Terrain and topology information collectively identify, for example, whether the road is 1) flat or inclined; 2) paved, concrete, crushed stone, or dirt; 3) in open or shaded areas, and 4) within certain area types. The location of the start and end points (e.g., a geographic location or position), the length of the desired route, and route characteristics are received as input to generate the closed-loop route. Route characteristics might include, for example, i) particular inclines/declines to modify the cardiovascular exercise from traversing the output closed route, ii) preferred types of terrain the output closed route includes, such as pavement or dirt paths, and iii) particular zones or areas to be included or avoided in the desired route.

Abstract: In accordance with exemplary embodiments, a radio frequency identification (RFID) device might employ channel-in-use sensing and time multiplexing transmission to prevent radio systems of RFID devices in close proximity to one another from transmitting while another one of the RFID devices is transmitting so as to reduce, for example, radio interference at the transmitting RFID device. RFID transceivers not transmitting might employ a random back off procedure once a close proximity transmission is detected so that the RFID devices do not repetitively try to seize the channel at approximately the same time.

Abstract: A method using a combination analog/DSL modem for deploying DSL services is disclosed. A combination analog/DSL modem is utilized at the subscriber premises. A telephone line is tested using the analog portion of the modem. In combination with information provided by the subscriber and records, suitability of the service line for DSL services may be accurately determined. DSL service is then ordered by the subscriber. Preferably, DSL services are deployed on top of the existing analog voice service line allowing service turn-on within a short period of time. The subscriber can have the ability to access a network using the DSL portion of the combination modem. If during modem testing, it is determined that the telephone line would not support DSL service, the subscriber would be informed that DSL service is currently not available for them. However, the subscriber could continue to use the analog portion of the combination modem.

Abstract: A versatile device is obtained with a PDA that includes means for cordless connecting to specialized accessories. The PDA can operate in its conventional mode, or it can be enhanced by interconnecting it with some or all of its accessories. In one embodiment, the PDA is combined with a cellular telephone that is adapted to physically mate with the PDA and form thereby a single integrated apparatus. In another embodiment, the PDA is combined with a landline telephone that is adapted to mate with the PDA and form thereby another single integrated apparatus. In a still another embodiment, the PDA (whether or not mated with a telecommunication device) is combined with a keyboard to form a laptop computer.

Abstract: A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system advantageously comprises a controller unit with Caller ID capabilities and one or more adjunct units that are bridged onto a single wire-pair at a user's residential location in a parallel electrical connection. These customer installable units are merely plugged into any telephone jack and share a telephone wire-pair with existing telephone extensions without interference. Such operation is possible since communication between the controller unit and the adjunct units is limited to a frequency band different from the audio frequency band used by the existing telephone extensions on the single wire-pair. The controller unit, in one configuration, operates as an answering machine with multiple mailboxes. This functionality is advantageously combined with Caller ID, intercom and speakerphone capabilities.

Abstract: A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system comprises a controller unit with Caller ID capabilities and one or more adjunct units that are all bridged onto a single wire-pair at a user's residential location in a parallel electrical connection. For facilitating a message routing capability, a mailbox of groups of telephone numbers are associated with a particular party at the residence. These telephone numbers are preprogrammed into the controller unit so that upon receipt of an incoming call from one of these telephone numbers, identified through caller ID, the incoming call is associated with the particular called party and the controller unit routes the incoming call directly to the called party's mail box where the calling party is able to leave a message.
