    Abstract: To maintain a synchronized wireless peer group, timing signals may be periodically transmitted by one or more devices in the wireless peer group. These periodic timing signals may be transmitted by different wireless devices in the peer group, distributing (sharing) the transmit power burden among the different wireless devices, increasing the useful operation time of the individual wireless devices. Similarly, the wireless peer group may monitor for timing signals received from devices that are not part of the wireless peer group. This monitoring burden may also be distributed (shared) among the devices in the peer group allowing for a greater sleep time for individual wireless devices, increasing the useful operation time of the individual wireless devices.

    Abstract: Apparatuses, devices, systems, and methods are provided for prevention of tampering with cables and associated systems. In one aspect, an anti-tamper adapter is provided that can inhibit or prohibit cable tampering for existing cables. In a further aspect, dummy plugs or blocking plugs can employ disclosed anti-tamper adapters to facilitate blocking ports or outlets that are intended to remain undisturbed for a period of time. The provided embodiments can economically and flexibly facilitate cable tamper prevention in a wide array of cable technologies.

    Abstract: A low cost high-efficiency all-digital transmitter using all-digital power amplifiers ("DPA") and various mapping techniques to generate an output signal, which substantially reproduces a baseband signal at a carrier frequency. A baseband signal generator generates a baseband signal which is quantized by a signal processor using a quantization map. A DPA control mapper outputs control signals to phase selectors using the quantized signal and a quantization table. Each phase selector receives one of the control signals and outputs a waveform at a carrier frequency with a phase corresponding to the control signals, or an inactive signal. Each DPA in a DPA array has an assigned weight, receives one of the waveforms from the phase selectors, and outputs a power signal according to the weight of the DPA and the phase of the received waveform. The combined power signal substantially reproduces the baseband signal at the carrier frequency.

    Abstract: Systems and methods for providing self-healing integrated circuits. The method is characterized in that the behavior of a circuit or a device in response to an input signal is observed. One or more operational parameters or characteristics of the circuit or the device are derived. A corrective action to bring the operational parameters or characteristics of the circuit or device within a desired range is deduced, if needed. The corrective action can be the application of a correction signal or a modification of one or more parameters or characteristics of an element in the circuit. The calculated corrective action, if needed, is applied to bring the operational parameters or characteristics of the circuit or device within the desired range. Optionally, the operational parameters or characteristics of the circuit or the device after the correction is effectuated can be checked.

    Abstract: According to one aspect, an integrated magnetic particle measurement device for detecting a presence or absence of magnetic particles in a sample volume includes at least one sensor cell having a differential sensor pair. An active sensor oscillator frequency is responsive to one or more magnetic particles situated within a sample volume. The sensor cell is configured to be operative in the absence of an externally applied magnetic field. A frequency measurement circuit provides as a time-multiplexed output a first count representative of the active sensor oscillator frequency and a second count representative of the reference sensor oscillator frequency. A calculated difference between the first count and the second count is indicative of a presence or an absence of one or more magnetic particles within the sample volume. An integrated magnetic particle measurement system array and a method for detecting one or more magnetic particles are also described.
