  • Patent number: 9639056
    Abstract: Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.

    Abstract: Methods and sensors for selective fluid sensing are provided. Each sensor includes a resonant inductor-capacitor-resistor (LCR) sensor that is coated with a sensing material. In order to collect data, an impedance spectrum is acquired over a relatively narrow frequency range, such as the resonant frequency range of the LCR circuit. A multivariate signature may be calculated from the acquired spectrum to discern the presence of certain fluids and/or fluid mixtures. The presence of fluids is detected by measuring the changes in dielectric, dimensional, resistance, charge transfer, and other changes in the properties of the materials employed by observing the changes in the resonant electronic properties of the circuit. By using a mathematical procedure, such as principal components analysis (PCA) and others, multiple fluids and mixtures can be detected in the presence of one another, even in a high humidity environment or an environment wherein one or more fluids has a substantially higher concentration (e.g.

  • Patent number: 9641969
    Abstract: In various example embodiments, a system and method for facilitating proximity detection and location tracking using a mobile wireless bridge are provided. The system includes a beacon badge, a beacon tag, and a real-time location services (“RTLS”) server communicatively coupled to the beacon badge, such as via a wireless network or the like. The beacon tag broadcasts a beacon message receivable by the beacon badge. The beacon badge determines whether it is proximate to the beacon badge based on the signal strength of the received beacon message. The beacon badge further communicates identifying information contained with the received beacon message to the RTLS server. The RTLS server uses the identifying information to determine the proximate location of the beacon badge.

  • Patent number: 9642218
    Abstract: A new apparatus, system, method and a computer readable memory are presented for lighting control using active wireless active feedback monitoring of behavioral activity of moving objects, for lighting control in an area of interest using, for example, a time dependence of a received signal strength parameter (RSSP) and a calculated standard deviation of the RSSP. Presence of moving objects (such as humans, pets/animals, cars and the like) within the range of an established wireless network tends to modulate the wireless signal strength between wireless nodes. Using the monitored variation in the standard deviation of the wireless signal strength between network nodes, behavioral activity of moving objects may be used to directly control ambient lighting conditions such as luminaire lumen output, color temperature, light distribution, and/or other lighting characteristics, based upon the level of behavioral activity of moving objects within an area of interest.
