Abstract: A power saving wire-free earpiece has a Bluetooth transceiver and a Bluetooth Low Energy (BLE) transceiver. A stream of audio from a remote source is separated into a local audio stream and a stream sent to the BLE transceiver for a remote earpiece. The earpiece is operative in a first and second mode, the first mode enabling the BT transceiver and BLE transceiver, the second mode enabling only the BLE transceiver for receiving remote streams of data. The first and second mode alternate so that the local and remote earpiece have substantially uniform current requirements.

Abstract: Methods and systems for managing signals by signal owners. Signals are indicators of data that are derived from data sources and abstracted to protect the underlying data. The signal owner first converts its own underlying data into a “signal” or indicator that represents the data without disclosing it or providing it. Signal sellers determine if they wants share signals based upon buyer, price, and other rules, including limitations on signal use. Signal buyers determine signal value based upon their objectives.

Abstract: A traffic radar system comprises a first radar transceiver assembly, a second radar transceiver assembly, a display, and a processing element. The first radar transceiver assembly transmits and receives radar beams and generates a first electronic signal corresponding to the received radar beam. The second radar transceiver assembly transmits and receives radar beams and generates a second electronic signal corresponding to the received radar beam. The display displays a plurality of speeds, each speed being a speed of a target vehicle. The processing element is configured to receive the first and second electronic signals, process the first electronic signal to determine speeds of target vehicles in the front zone, process the second electronic signal to determine speeds of target vehicles in the rear zone, and control the display to display the speeds of target vehicles in the front zone or target vehicles in the rear zone based on predetermined parameters.

Abstract: A periodic output generator has a first clock source coupled to a first counter and a second clock source with a frequency greater than the first clock source, the second clock source coupled to a second counter, the first clock source operating continuously, the second clock source enabled when the first clock source reaches a count C1. The second clock source generates an output when a count C2 is reached, and the counters are reset and the process repeats. In another example, a timestamp generator has a high speed clock and a real time clock operative on a low speed clock. The timestamp generator receives an external event, turns on the high speed clock generator and counts high speed clock cycles C until the arrival of the next time stamp, and computes an event timestamp as the next timestamp less c/f, less the startup time of the high speed clock.

Abstract: Methods and systems for providing an automated virtualized signal marketplace or exchange for signals from distributed data sources that are controlled by a multiplicity of signal sellers or signal owners, including at least one data correlation engine that is operable for processing the signals to generate at least one correlation value relating to a specific objective for signal buyers corresponding to the behavior of the object and/or the activity and/or the event. Signals are indicators of data that are derived from data sources and abstracted to protect the underlying data. Each entity that sells data in the virtual marketplace first converts data into a “signal” or indicator that represents the data without disclosing it or providing it. Signal sellers determine if they wants share signals based upon buyer, price, and other rules, including limitations on signal use. Signal buyers determine signal value based upon their objectives.

Abstract: A neurotrophic electrode system includes a non-conductive cone, a multi-channel electrode assembly, a dielectric ribbon and a neurite-attracting substance disposed within the cone. The non-conductive cone consists essentially of a material that is stable in a neural environment and defines a cavity. The cavity opens to a small opening at a first end of the cone and opens to a large opening at a second end of the cone that is opposite the first end. The multi-channel electrode assembly includes at least two recording sites that are disposed within the cavity defined by the cone. Each recording site is coupled to a wire that extends out of the large end of the cone. Each wire ends in a connection pad. The dielectric ribbon encases all of the wires but exposes each recording site and exposes each connection pad.

Abstract: A power saving receiver has a controller which is operative to remove power from the receiver when a threshold is exceeded during reception of a packet. The threshold level is formed by comparison of any of: signal energy of unoccupied subcarriers less the signal energy in occupied subcarriers; signal energy in a first range of occupied subcarriers compared to signal energy in a different range of occupied subcarriers; error vector magnitude from a first set of subcarriers to a second set of subcarriers in a different spectral region of the channel; cyclic prefix cross-correlation, or common phase error increase.

Abstract: A preamble detector for a Bluetooth Long Range includes a receiver for forming baseband samples from Bluetooth packets and a preamble detect controller for enabling and disabling power to the receiver. Where the preamble duration is Tcyc, the preamble detector turns on for a preamble detect time T1 and turns off for a duration T2, where T2=Tcyc?2*T1. A series of hierarchical decisions is made on sequentially increasing intervals of time based on an accumulated correlation result of correlating the baseband samples against a SYNC sequence to power the receiver back down before the end of the T1 period when the accumulated correlation result is below a threshold and continues to a subsequent correlation interval when the accumulated correlation result is above a threshold, where the threshold is established to have at least a 20% false alarm rate for preamble detection.
