Abstract: A magnetic resonance (MR) compatible transducer for magnetic resonance elastography applications has a cantilevered drive element a free end of which is arranged in use to move reciprocally, and a flexible non-conductive connection rod slidably disposed within a flexible non-conductive sleeve. The connection rod is affixed at a proximal end to the cantilevered drive element via a proximal flexible connection piece that in use accommodates the slight rotational movement of the cantilevered drive element as it reciprocates about its secured end, whilst translating the rotational reciprocation of the cantilevered drive element into a pure translational reciprocation of the connection rod within the sleeve. The distal end of the connection rod is affixed against a protrusion connected to another cantilevered driven element, upon which is mounted a piston element that in use contacts the subject.

Abstract: Occupancy data over time is received for each of several spaces within a building from occupancy sensors that are disposed within each of the spaces. An occupancy value is determined for each of at least some of the several spaces based on the received occupancy data, each occupancy value representative of a percent of time that the respective space was occupied over an identified period of time. The space that had a highest occupancy value over the identified period of time is identified. A utilization value is determined for each of the spaces, wherein the utilization value is representative of a ratio of the occupancy value of the respective space and the highest occupancy value. An operation of the building is changed based at least in part on the utilization value of at least one of the plurality of spaces.

Abstract: A method for trajectory planning of a vehicle includes storing a desired driving path of the vehicle. The method then includes observing external interference factors (2) on the vehicle. The method proceeds by using the driving path and the interference factors (2) to calculate tracking errors (3) and secondary conditions (4). The method then includes optimizing a trajectory (5) in such a way that the tracking errors (3) are reduced within the secondary conditions (4). A corresponding device, a corresponding computer program, and a corresponding storage medium also are provided.
