  • Patent number: 7894948
    Abstract: Systems and methods that may be employed to communicate location information between two or more aerial vehicles or other types of vehicles or other entities, and/or that may be used to facilitate coordinated operations of two or more such entities. In one example, an aerial vehicle may be kept aware of one or more location (e.g., longitude, latitude, etc.) and/or flight characteristics (e.g., altitude, directional heading, airspeed, attitude, etc.) of one or more other adjacent aerial vehicles, and each such aerial vehicle may use that location information to adjust its flight path to maintain a safe sphere of empty airspace around itself.

  • Patent number: 7889777
    Abstract: A frequency hopping coordinator device scans a plurality of frequencies for request for services messages during an unused time slot in order to detect a request for service preamble on one of the frequencies and, responsive thereto, send a service packet message to an end device from which it received the request for service message on the one frequency. The service packet includes a current frequency sequence value of the coordinator device's pseudo-random number sequence and beacon timing information that indicates when periodic beacon messages occur. An endpoint device sends a request for services message on a first frequency of the plurality of frequencies scanned by the coordinator device that includes a preamble identifiable by the coordinator device. The endpoint device receives the service packet message and, responsive thereto, changes the end point's current frequency sequence value and timing information to match the values sent by the coordinator device.

  • Patent number: 7885688
    Abstract: A signal of interest (SOI) may be selected from among a plurality of cochannel signals based on one or more internal or external structural feature/s of the SOI, e.g., automatically selected based on any one or more internal or external structural features of the SOI that is known a priori. Examples of such internal structural features include, but are not limited to, number, frequency and/or absolute or relative signal strength (signal to noise ratio) of one or more transmitted signal components (e.g., pilot tones, squelch tones, etc.) present in the SOI; absence of a signal component at a given frequency in the SOI (i.e., present as a “dead spot” at a given frequency within the SOI); signal strength versus frequency profile of the SOI, signal strength versus time domain profile of the SOI, transient characteristics, time versus frequency profile, etc.

  • Patent number: 7859331
    Abstract: Methods and systems are disclosed for predictive feedback compensation (PFC) circuitry for suppressing distortions caused by supply voltage variations and output amplitude switching non-idealities in pulse width modulated (PWM) switching amplifiers by pre-compensating the PWM input based upon the supply voltage or output pulse amplitude. Output amplitude errors associated with previous PWM output signals are used to predict output amplitude errors expected for future PWM output signals. These predicted output amplitude errors are then used to adjust the pulse widths for the future PWM output signals. Traditional feedback techniques can also be used in conjunction with the predictive feedback compensation (PFC) circuitry.

In one embodiment, the first and second materials are substantially the same. In one embodiment, the second material is conductive and is different than the first material. In another embodiment, a method for fabricating a MEMS structure comprises first forming a member above a substrate. A coupler comprised of a conductive material is then formed to connect the member with the substrate.

  • Patent number: 7855649
    Abstract: Systems and methods are disclosed for a tamper resistant RFID (radio frequency identification) tags that overcome the problems existing with previous RFID tags. The tamper resistant RFID tags described herein are particularly useful for tracking of liquid propane gas (LPG) containers and/or other types of containers or objects. Removal of the RFID tag, after it is attached, will destroy and/or render inoperable the RFID transponder within the tag so that removal and re-use is not practical or possible. One key feature of this tamper resistant RFID tag is the use of adhesive materials with differing adhesion characteristics with respect to the container material (e.g., metal) and the housing for the RFID tag (e.g., plastic) so that the RFID tag will tend to be destroyed when removal is attempted.

  • Patent number: 7844292
    Abstract: Systems and methods are disclosed for in-band control signaling using bandwidth distributed encoding to send modulated control carrier signals with analog voice signals in the same voice frequency band. A transmitting device generates control carrier signals spread over a voice frequency band, combines them with analog voice signals in the voice frequency band, and transmits the combined signals over a communication channel. The transmitting device can use a control signal encoder to apply a pseudo-random code to the control carrier signal in order to spread it over a voice frequency band. As such, control signals are sent as in-band signals without significantly degrading the voice signals. A receiving device receives the combined signals within the voice frequency band. The receiving device demodulates the combined signal and uses matching pseudo-random codes to determine if a control signal has been sent. The receiving device also reproduces the voice signals themselves.

  • Patent number: 7808995
    Abstract: One or more nodes of a network may be configured to provide substitute header information for insertion into a received data packet and then to retransmit the data packet with the modified header information to other network destinations. One or more other downstream nodes may be configured to do likewise, thus allowing a packet to proceed through a selected number of multiple destinations in the network without being shortened, and so that the number of control words required in each packet is reduced, in increasing data bandwidth for the network.
