  • Patent number: 10338055
    Abstract: A multi-frequency inductive sensing system can be used for spectrographic material analysis of a conductive target material (such as tissue) based on electrical impedance spectroscopy. An inductive senor can be driven with an excitation current at multiple sensor excitation frequencies (?) to project a time-varying magnetic field into a sensing area on the surface of the target material, inducing eddy currents within the target material. The inductive sensor can be characterized by a sensor impedance Z(?) as a function of the sensor excitation frequency (?), and the resulting induced eddy currents. Multiple sensor impedance Zs(?) measurements, at the multiple sensor excitation frequencies (?), can be determined, which represent electromagnetic properties of the target material (such as permittivity ?, permeability ?, and resistivity ?), based on the induced eddy currents.

  • Patent number: 10340252
    Abstract: A high-voltage transistor (HVT) structure adapts a low-voltage transistor (LUT) to high-voltage environments. The HVT structure includes a drain node, a source node, a control gate, and a field electrode. The drain node and the source node define a conductive channel, in which mobilized charges are regulated by the control gate. While being isolated from the control gate, the field electrode is configured to spread the mobilized charges in response to a field voltage. The field electrode is structured and routed to prevent charge sharing with any one of the drain node, source node, or control gate. Advantageously, the isolated field electrode minimizes the capacitance of the control gate as well as the drain and source nodes, such that the HVT can switch with less power loss and a more robust performance in a high-voltage environment.

  • Patent number: 10340821
    Abstract: Low speed and high speed estimates of rotor angle and speed relative to the stator are received from a low speed estimator and a high speed estimator, respectively. LS_?_EST and a subset of torque-controlling I_Q trajectory curve (“IQTC”) parameter values appropriate to low speed rotor operation are selected for rotor speeds below a low speed threshold value ?_LOW_THRS. HS_?_EST and a subset of IQTC curve parameter values appropriate to high speed rotor operation are selected for rotor speeds above a high speed threshold value ?_HIGH_THRS.

  • Patent number: 10340687
    Abstract: Disclosed examples include an ESD protection circuit to protect an IC pad with high immunity against hot-plug surges, switching noise or other transient voltage conditions on the protected pad. The ESD protection circuit includes a clamp transistor and a trigger circuit responsive to rises in the protected pad voltage at or above a first slew rate to turn on the clamp transistor, as well as a second circuit coupled between the control terminal of the clamp transistor and a voltage supply node.
