Abstract:
A sensing system for sensing the condition of an object comprises a transducer arranged to generate pressure waves directed at the object and detection means, such as a pressure wave detector, arranged to detect cavitation or other processes in the object. The system further comprises processing means arranged to receive detection signals from the detection means, to process the detection signals to measure a signal parameter of the detection signals that varies with a parameter of the object, and may generate a sensor output that varies in response to changes in the signal parameter.
Abstract:
Various apparatus and methods using phase change materials are disclosed. In one aspect, a method of operating a computing device that has a first semiconductor chip with a first phase change material and a second semiconductor chip with a second phase change material is provided. The method includes determining if the first semiconductor chip phase change material has available thermal capacity. If the first semiconductor chip phase change material has available thermal capacity then the first semiconductor chip is instructed to operate in sprint mode. The first semiconductor chip is instructed to perform a first computing task while in sprint mode.
Abstract:
Apparatus for locating bubbles in a subject comprises a plurality of pressure wave detectors arranged to operate as passive detectors to generate output signals in response to the receipt of pressure waves generated at a source comprising at least one bubble, and processing means arranged to receive signals from the detectors and to determine from the signals the position of the source.

Abstract:
Provided are a method and apparatus to measure in real time the hearing ability of a user in a game environment of a mobile device. The method includes generating a series of sound patterns and visual patterns for a combination of a specific frequency and level of sound, and extracting ear characteristics of the user based on the user's responses to the series of sound patterns and visual patterns.
Abstract:
A method of at least partially removing the nucleus pulposus of an intervertebral disc comprising the nucleus and an annulus surrounding the nucleus is described. The method comprises the steps of : insonating the nucleus with ultrasound thereby to cause at least partial fragmentation of the nucleus; and extracting at least part of the fragmented nucleus. A system for performing the method is also described.
