  • Patent number: 10408671
    Abstract: Systems and methods are described that may provide audio information about an environment around a wearable device. Such audio information may be correlated with other biometric data to provide physiological information, e.g. regarding a wearer of the wearable device. For example, an illustrative method includes receiving an audio signal via a microphone of a wearable device and rectifying the audio signal with a peak detector. The method further includes amplifying the rectified signal with a logarithmic amplifier and causing an analog to digital converter (ADC) to sample the logarithmic signal. The method also includes causing the ADC to convert the sampled logarithmic signal to a digital output and storing the digital output in a memory of the wearable device. In some embodiments, the method includes transmitting the digital output to a computing device, which may correlate the digital output with other biometric data.

  • Patent number: 10393552
    Abstract: The invention relates to a sensor system, and more particularly, to systems, devices and methods of processing a sensing signal from a sensor to generate amplitude and phase controls for driving this sensor in a controlled manner and enabling synchronized operation of the sensor system. A signal processor in the sensor system comprises a sensor readout circuit, an amplitude controller and a phase controller. A subset of functional blocks in the signal processor may alternate between active and inactive power saving durations. During the active power saving durations, the subset of functional blocks are powered off or functionally disabled to conserve power consumption. The amplitude and phase controls are latched for the purposes of properly maintaining the driving signal and the system clock. During the subsequent inactive power saving durations, the subset of functional blocks return to normal operation to refresh the amplitude and phase controls.

  • Patent number: 10387585
    Abstract: A system and method extends model verification through the creation of composite test objectives. A composite objective includes two or more logically or temporally combined standard or basic test objectives. The basic test objectives selected to form a composite test may be automatically generated by the system or method, or they may be custom defined. A composite test objective represents a new coverage objective that extends model coverage analysis beyond the coverage that is available with the basic test objectives. The system and method also automatically generates one or more test cases for achieving the composite objective. The test cases include input data values for the model, and may cause the specified logical or temporal combination of basic test objectives to evaluate to true at least once during simulation of the model or according to the temporal combination.

  • Patent number: 10386339
    Abstract: A modal vibration analysis system and corresponding method is provided. Exciters are coupled to a structure under test for generating vibrations in the structure. Sensors are coupled to the structure at multiple locations for sensing vibrations generated in response to the excitations. A controller provides drive signals to the exciters such that the sensor signals have a target output spectrum with specified characteristics in multiple designated frequency domains of the spectrum, characterized by a random phase for each frequency. Modal analysis processes digitized sensor signals with a Fast Fourier Transform conducted at two or more specified data sampling rates to synthesize a spectrum containing data points with finer frequency resolution for lower frequency range, and regular frequency resolution for higher frequency range. From the multi-resolution spectra, natural frequencies and damping coefficients are determined at each mode, and a mode shape at each natural frequency is computed.

  • Patent number: 10353045
    Abstract: Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured. Many measurements in test and measurement or calibration applications regularly require accuracies within the sub-part per million (ppm) range, e.g. 0.1 ppm to 1.0 ppm. However, the continued drive for improved accuracy in calibration, standards, and measurements on circuits and components means many measurements and measurement systems are operating at 50 parts per billion (ppb) and below to approximately 10 ppb. At these levels even relatively simple passive elements such as voltage dividers cannot be used without calibration and that these calibrations may be required at frequencies substantially higher than the other elements within the test and measurement equipment. Accordingly, the inventors have established a self-contained voltage divider with internal calibration allowing the voltage divider to be calibrated for every measurement if necessary.
