  • Patent number: 9692262
    Abstract: A support structure is used to mount the stator of a rotating electrical machine (e.g. a motor or generator). The support structure includes a rigid external support frame (6). To minimise the transmission of vibrations caused by stator electromagnetic forces into the external support frame (6), at least one sandwich anti-vibration mount (14a) is secured between the external support frame (6) and a part of the stator (28). The mount (14a) is oriented relative to the stator such that it experiences compression loading in a substantially tangential direction of the stator and radial shear loading in a substantially radial direction of the stator during operation of the rotating electrical machine. The sandwich anti-vibration mount (14a, 14b) is pre-loaded with a pre-determined compression load substantially along its compression axis (Ac).

  • Patent number: 9692322
    Abstract: An inverter phase leg for a DC-AC inverter includes a high supply line and a low supply line across which a DC voltage is provided. A high side gate controlled switch is connected to the high supply line and a low side gate controlled switch is connected to the low supply line, with an output node between the high side switch and the low side switch. An inverting driver is connected to the high side gate controlled switch. The inverting driver's voltage source is configured in such a way as to hold the high side gate controlled switch off during the turn on cycle until the driver output has overcome the negative bias generated across the high side switch gate, producing high immunity to spurious turn on. A digital isolator is connected between the inverting driver and a control signal for switching the inverter phase leg. A differential transmitter and differential receiver may be used to further increase noise immunity.

  • Patent number: 9689996
    Abstract: Improved imaging systems are disclosed. More particularly, the present disclosure provides for an improved image sensor assembly for an imaging system, the image sensor assembly having an integrated photodetector array and its associated data acquisition electronics fabricated on the same substrate. By integrating the electronics on the same substrate as the photodetector array, this thereby reduces fabrications costs, and reduces interconnect complexity. Since both the photodiode contacts and the associated electronics are on the same substrate/plane, this thereby substantially eliminates certain expensive/time-consuming processing techniques. Moreover, the co-location of the electronics next to or proximal to the photodetector array provides for a much finer resolution detector assembly since the interconnect bottleneck between the electronics and the photodetector array is substantially eliminated/reduced.
