Abstract: Chopping techniques that suppress fold-back into the signal band and spreads the offset across the spectrum are described. By using various techniques, chopping may be performed with a variable frequency clock to spread the offset across the signal spectrum. Spreading the offset across the signal spectrum means that there are no longer large spurious tones at a few frequencies.

Abstract: The present disclosure provides a sensing assembly for sensing an analyte. The sensing assembly comprises multiple test electrodes configured to provide signals from multiple independent measurements in response to the analyte. Alternatively or additionally, the multiple test electrodes are configured to produce different transient responses in response to a given concentration of the analyte.

Abstract: The present disclosure provides tunnel magnetoresistive (TMR) multi-turn (MT) sensors with improved sensor read-out and methods of manufacturing said sensors. In some examples, the TMR sensing elements of the MT sensor are each provided with two or more electrical contacts for performing current-in-plane tunnelling measurements. The two or more electrical contacts may be provided above or below the TMR sensing elements. In further examples, one or more read-out pillars formed from TMR sensing material may be provided, the read-out pillars being electrically connected to one or more TMR sensing elements. The read-out pillars are configured such that the resistance observed in the read-out pillars is negligible or near-negligible relative to that observed in the TMR sensing elements, such that the measured output signal only reflects the change in resistance experience by the TMR sensing elements in the presence of an externally rotating magnetic field. In the arrangements described herein, the length of the TMR sensing elements can be significantly reduced and tighter sensor spiral can be achieved, thus reducing the overall size and defectivity of the MT sensor.

Abstract: A network interface module for coupling a host device to a switched network as a network node is described. The network interface module comprises a single half-duplex port for communicatively coupling to a shared bus of the switched network, at least one frame queue sized to store one multicast read frame received via the shared bus, and logic circuitry. The logic circuitry is configured to decode a read command for the interface module included in a payload of the multicast read frame that includes multiple read commands for other network nodes of the switched network, and transmit a response frame including read data on the shared bus when detecting the shared bus is available for transmitting.

Abstract: A three-phase power meter can monitor power on both 3-wire and 4-wire power lines. The power meter measures at least two voltages between phase conductors of the power line, and at least one voltage between a phase conductor and a neutral conductor of the power line when the neutral conductor is available. Using at least some of the measured voltages, the power meter can then operate in a first mode when coupled to a 3-wire power line to determine power on the power line based on the measured voltages, or operate in a second mode when coupled to a 4-wire power line to determine power on the power line based on the measured voltages.

Abstract: Microelectromechanical systems (MEMS) switches are disclosed. Parallel configurations of back-to-back MEMS switches are disclosed in some embodiments. An isolation connection of constant electrical potential may be made to a midpoint of the back-to-back switches. In some embodiments, a separate MEMS switch is provided as a shunt switch for the main MEMS switch. MEMS switch device configurations having multiple switchable signal paths each coupling a common input electrode to a respective output electrode are also disclosed. The MEMS switch device includes shunt switches each coupling a respective output electrode to a reference potential. The presence of a shunt switch coupled to an output electrode enhances the isolation of the signal path corresponding to that output electrode when the path is open.

Abstract: Systems and methods are provided for architectures for an analog feedback class D modulator that increase the power efficiency of the class D modulator. In particular, systems and methods are provided for an analog feedback class D modulator having a digital feed-forward loop. The digital feed-forward loop allows for removal of signal content from an input to an analog-to-digital converter, such that the ADC processes just noise and/or error. Using the techniques discussed herein, the loop filter is low power as it processes error content but not signal content.

Abstract: New antenna designs for realizing circularly-polarized antennas with a wide scanning range are disclosed. The designs h are based on arranging four sequentially fed antenna patches to be considered as a single antenna element, referred to as a “super-element,” in the overall phased array. An example super-element includes relatively short transmission lines to provide excitations for the vertically and horizontally polarized fields, with the transmission lines for the vertically and horizontally polarized fields being perpendicular to one other. A parasitic transmission line may be placed around a part of each antenna patch of the super-element to serve as a coupler to further enforce the field vector direction for keeping the circular polarization. With such designs, an axial ratio below 3.6 dB for scanning angles of at least 75 degrees at 39.5 GHz may be achieved.

Abstract: A system for measuring a complex impedance associated with an arrangement of battery or fuel cells in an energy storage system may include a controller, a current measurement device, and voltage measurement devices. The current measurement device may be shared by the cells for measuring a test current provided to the cells. The voltage measurement devices may be respectively coupled across corresponding cells. The controller, the current measurement device, and the voltage measurement devices may be coupled together using a DC isolated bus. The controller may determine a respective complex impedance of corresponding groups of the cells using a complex voltage measured by a respective voltage measurement device coupled across a corresponding group of the cells and a complex current measured by the complex current measurement device. The controller may be configured to compensate for an asynchrony between particular ones of the current measurement device and the voltage measurement devices via the DC isolated bus.
