摘要： Apparatus for the wireless transmission of data, and preferably also of power, across a space between a length of production tubing and a surrounding casing in a petrochemical well, includes a pair of inductively-coupled coils, a first of which is located on the exterior of the production tubing generally coaxially therewith, and the second of which is located on the interior of the casing generally coaxially therewith. This may be used in particular as part of a system for transmitting power and data to/from a sensor monitoring the pressure and/or other environmental conditions within the “B” annulus B of a sub-sea well.

摘要： Reader apparatus for receiving data from a transponder in the body of a patient, for example a femoral nail. The apparatus includes an antenna which can be varied in size and shape to fit patients, the size and shape of whose bodies vary significantly. A variable impedance unit is included to maximise power matching between the antenna and a reader unit for a given antenna configuration.

摘要： An electronic circuit breaker including a two stage detection mechanism; an instantaneous trip operating at a first threshold and a delayed trip such operating at a second lower threshold. This is advantageous in maintaining operation during very short transient load peaks, which do not warrant isolation from the supply. The breaker can be line powered, can be reset remotely by controlling the line power, and can be implemented entirely in solid state electronics. As such it requires little or no service or maintenance.
摘要翻译： 一种电子断路器，包括两级检测机构; 在第一阈值操作的瞬时跳闸和在第二较低阈值处操作的延迟跳闸。 这在保持在非常短的瞬态负载峰值期间的操作是有利的，这不需要与电源隔离。 断路器可以线路供电，可以通过控制线路电源远程复位，并且可以完全在固态电子器件中实现。 因此，它几乎不需要服务或维护。
