Abstract: The present disclosure relates to circuitry for driving a load. The circuitry comprises driver circuitry configured to generate a drive signal, based on an input signal to the driver circuitry, for driving the load, and commutator circuitry for coupling the driver circuitry to the load. The commutator circuitry is configured to alternate between commutation states in response to a level of the drive signal meeting a drive signal threshold or in response to a level of the input signal meeting a first input signal threshold. The circuitry is configured to apply an offset to the input signal when the input signal is below a second input signal threshold so as to increase a minimum level of the drive signal above the drive signal threshold or to increase a minimum level of the input signal above the first input signal threshold.

Abstract: An ultrasound imaging system has an array of ultrasound transducers comprising a set of sub-arrays of transducers. Each transducer (100) has an analogue buffer (106). Each sub-array of transducers has a signal path (102, 104) from within the array of ultrasound transducers to outside the array of ultrasound transducers which comprises one or more hops between the buffers (106). To reduce the signal line length from inside the array of ultrasound transducers to the periphery, at least some multiple hops between buffers (106) are provided. Each buffer hop introduces a delay, but prevents signal degradation so that a large number of analog signals can be transmitted across the large area ASIC of the transducer array.

Abstract: The invention discloses microparticle multi-channel time-sharing separation device and method based on an arcuate interdigital transducer. An arcuate interdigitated electrode is connected to an output channel of a signal generator. The arcuate interdigitated electrode and a polydimethylsiloxane (PDMS) microfluidic channel are placed on a lithium niobate chip. The arcuate interdigitated electrode is mainly formed by an interdigitated electrode being asymmetrically bent from a straight line into an arcuate curve. Two electrode ends of the arcuate interdigitated electrodes are asymmetrically arranged with one end big and another end small. The PDMS microfluidic channel includes a main flow channel, two inlet ends, and multiple outlet ends. The main flow channel is an approximately arcuate flow channel arranged around an outer side of the arcuate interdigitated electrode. Particles are patterned in a coverage section of surface acoustic waves to complete separation of microparticles.
