Abstract: A retrievable subsea apparatus (1) with a pressure and volume compensating system, the apparatus comprising: a housing (1?) having in its interior a control system (9) located in a first section (3) thereof and an operating unit (6) located in a second section (4) thereof. The apparatus further comprises a penetrator (2) which constitutes an interface between the first section (3) and the second section (4), wherein the first section (3) has a substantially constant first pressure. An external pressure compensator (5, 5?) is associated with the second section (4) having a second pressure. The operating unit (6) comprises at least a first sub-unit (6?) and at least a second sub-unit (6?). The second section (4) is subdivided into at least a first sub-section (4?) and at least a second sub-section (4?) which is sealed off from the first 1,1 section (4?) and being associated with respective sub-unit (6?, 6?).

Abstract: A wireless vibration sensor suitable for connection to a distributed industrial control system arranged with a wireless network for communication of process data or control information. The wireless vibration sensor includes at least one sensor, a wireless radio transmitter, and a base part for mounting it firmly on equipment or a structure. The wireless sensor is arranged with a battery and a power storage device. A method for powering up the wireless sensor during active cycles is also described.

Abstract: An apparatus for assisting percutaneous light beam guided biopsy, having means for rotating a laser device about first and second rotation axes, the laser device providing its laser beam along an axis intersecting an intersection point between the first and second rotation axes and at right angles thereto. Inclinometers are installed for providing signal values as a function of two- or three-dimensional orientation directions of the said laser device relative to direction of gravitation. Encoding means provide feedback of rotary position information of the laser device. Comparing means compare set calculated instrument insertion angle values, provided from an input device, with encoder feedback signals and inclinometer signals and inhibits rotation operation of the laser device upon reaching specific threshold values.
