Abstract: Systems and methods for low-power single-wire communication are provided. In some embodiments, a method of operation of a transmitter to transmit a data word to a receiver using low-power single-wire communication includes receiving the data word to be transmitted to the receiver. The method also includes encoding the data word to be transmitted in a Pulsed Index Communication (PIC) format to produce a PIC data word and transmitting the PIC data word to the receiver. In this way, the transmitter may be able to transmit an increased amount of data while maintaining a simple communication protocol that uses low power and does not require a Clock-Data Recovery circuit.

Abstract: An electrocardiogram (ECG) processor is disclosed. The ECG processor includes ECG sampling circuitry configured in a first mode to acquire a continuous ECG sample set from an ECG signal by digitally sampling the ECG signal at a Nyquist rate for a first predetermined number of heartbeats and in a second mode to acquire a non-continuous ECG sample set from the ECG signal for a second predetermined number of heartbeats by digitally sampling active regions of the ECG signal that contain a PQRST complex and not from silent regions between adjacent PQRST complexes. The ECG processor also includes processing circuitry configured to determine from the continuous ECG sample set relative locations of the active regions and provide the relative locations of the active regions to the ECG sampling circuitry for sampling the ECG signal in the second mode.

Abstract: A switched capacitor DC-DC converter, which includes a pulse frequency modulation circuit, a multiplexing pulse-width modulation circuit, and a switched capacitive element, is disclosed. The switched capacitive element is coupled between the pulse frequency modulation circuit and the multiplexing pulse-width modulation circuit. The pulse frequency modulation circuit uses a DC source signal to charge the switched capacitive element. The pulse frequency modulation circuit provides a group of output signals by multiplexing the switched capacitive element and reduces reverse current to the switched capacitive element when updating each of the group of output signals.

Abstract: The various embodiments herein provide a Uniform Circular Displaced Sensor Array (UC-DSA) system and method for measuring/estimating Direction of Arrival (DOA) of a wireless signal. The UC-DSA system comprises at least a set of two circular antenna arrays. The two circular antenna arrays have a number of elements. A Radio frequency (RF) receiver captures a wireless signal incident on a circular antenna array. A Direction of Arrival (DOA) estimator processes a received input signal and a Triangulation system provides the exact location of the source of the wireless signal. The two circular antenna arrays with the same number of elements are placed on different radii, and are shifted to have equal separation between inner elements and outer elements.

Abstract: A multi-standard transmitter architecture with digitally upconverted intermediate frequency (IF) outphased signals is disclosed. The transmitter architecture includes a Gallium Nitride (GaN) power amplifier (PA) circuit having a Current Mode Class-D (CMCD) configuration. The GaN PA circuit includes a lower switching device electrically coupled to an input to receive an input RF signal and an upper switching device to switchably electrically couple the first switching device to a power supply to drive an antenna circuit based on the input RF signal. Thus, a reconfigurable transmitter architecture is disclosed that utilizes a high-speed Gallium Nitride (GaN) driver to achieve a peak drain efficiency of at least 85% while delivering output power of 10 W at 1 GHz frequency, for example.

Abstract: The location and morphology of an electrostatically manipulated flame can be controlled through the action of an electrostatic field on the flame, virtually independently of overall mixture composition and imposed strain rate. An electrostatically controlled burner can manipulate a position of a flame between an oxidizer source and a fuel source by way of one or more electrodes configured to produce an electrostatic field proximate to one of the fuel source and the oxidizer source.

Abstract: Architecture and a method for maximally stable extremal regions (MSERs)-based detection of exudates in an ocular fundus is disclosed. The architecture includes a communication interface to receive pixels of an ocular fundus image. The architecture further includes processing circuitry that is coupled to the communication interface. The processing circuitry is configured to automatically provide labels for light image regions and dark image regions within the ocular fundus image for a given intensity threshold and find MSERs within the ocular fundus image based on the labels. The architecture also determines MSER regions based on the MSER criteria and then highlights the pixels of the ocular fundus image that are located within MSER regions to indicate the exudates in the ocular fundus. The architecture is further configured to determine MSER ellipses parameters based on MSER regions and MSER criteria and then highlight the locations of the exudates in the ocular fundus.

Abstract: A multi-axis accelerometer may include a proof mass, a first electrode set, and a second electrode set. The first electrode set may detect acceleration along a second axis of the accelerometer, and may include a first electrode (C1) and a second electrode (C2). The second electrode set may detect acceleration along a first axis of the accelerometer that is orthogonal to the second axis, and may include a third electrode (C3) and a fourth electrode (C4). Application of a force along only the second axis may result in the exhibition of a non-zero change in differential capacitance between at least C1 and C2, but a zero net change in the differential capacitance between at least C3 and C4. As such, the accelerometer may exhibit little or no cross axis sensitivity in response to the applied force.
