    Abstract: An ultrasound generator comprising a signal generator and a transducer, and a method of generating ultrasound. The signal generator is arranged to receive, generate or calculate when instructed a modulating signal with a magnitude that varies within a first range, the signal generator is further arranged to generate a pulsed drive signal having a predefined first relationship to the modulating signal, the pulsed drive signal having at least a zero output level, a positive output level and a negative output level, wherein the position and width of pulses are defined by at least first and second switching angles per half cycle of the modulating signal. The transducer is arranged to generate ultrasound in response to the pulsed drive signal. The first relationship is selected such that within at least part of the range of magnitude of the modulating signal the first and second switching angles are adjusted simultaneously to provide for an increase or decrease in the magnitude of the fundamental frequency of the pulsed drive signal corresponding to an increase or decrease in the magnitude of the modulating signal. The first relationship is also selected such that a selected harmonic component of the generated pulsed drive signal is maintained below a first threshold.

    Abstract: An implantable device for monitoring an intra-articular joint environment corresponding to a joint body, for example a bone or a prosthetic joint component. The implantable device comprises: a sensor module configured to measure data indicative of at least one parameter of an intra-articular joint environment corresponding to a joint body; a communications unit operatively coupled to the sensor module and configured to transmit the measured data to an external device; and a rechargeable battery configured to power the sensor module and the communications unit, wherein the sensor module, the power supply and the communications unit are contained within a capsule, wherein the capsule is releasably mountable within an opening of the joint body, and wherein, when the capsule is releasably mounted within the opening of the joint body, the sensor module is configured to monitor the at least one parameter of the intra-articular joint environment.
