  • Semiconductor device having isolation trenches
    Patent number: 9048116
    Abstract: A semiconductor uses an isolation trench, and one or more additional trenches to those required for isolation are provided. These additional trenches can be connected between a transistor gate and the drain to provide additional gate-drain capacitance, or else they can be used to form series impedance coupled to the transistor gate. These measures can be used separately or in combination to reduce the switching speed and thereby reduce current spikes.

  • Control of a loudspeaker output
    Patent number: 9042561
    Abstract: A loudspeaker drive circuit has a microphone which forms part of an acoustic echo cancellation system. An input signal is processed before application to a loudspeaker driver, and the processing is controlled in dependence on the echo cancellation system performance, such as to control the extent to which the loudspeaker is driven into a non-linear operating region. In this way, the linearity can be controlled so as to provide an excursion limit, without needing a model of the loudspeaker or additional dedicated sensors.

  • Battery cell temperature detection
    Patent number: 9035619
    Abstract: Temperature characteristics of battery cells are detected. In accordance with one or more embodiments, an intercept frequency is detected for each battery cell, at which frequency an imaginary part of a plot of impedance values of the battery cell exhibits a zero crossing. The impedance values correspond to current injected into the cell. A temperature of the cell is determined based upon the detected intercept frequency for the cell and stored data that models operation of the cell. Various approaches are implemented with different types of circuits coupled to detect the impedance values of the respective cells.

  • Apparatus and method for molecule detection using nanopores
    Patent number: 9034637
    Abstract: A detector device comprises a substrate (50), a source region (S) and a drain region (D), and a channel region (65) between the source and drain regions. A nanopore (54) passes through the channel region, and connects fluid chambers (56,58) on opposite sides of the substrate. A voltage bias is provided between the fluid chambers, the source and drain regions and a charge flow between the source and drain regions is sensed. The device uses a nanopore for the confinement of a sample under test (for example nucleotides) close to a sensor. The size of the sensor can be made similar to the spacing of adjacent nucleotides in a DNA strand. In this way, the disadvantages of PCR based techniques for DNA sequencing are avoided, and single nucleotide resolution can be attained.
