Abstract: A switch device (10) and method for generation of energy for operating the switch device (10), wherein the switch device (10) is provided with a drive unit (120) interacting with an actuation device operable by a user, and with a moving device (130) configured to be set in motion by the drive unit (120), and with an energy harvester (132, 140, 140a) for providing energy to the switch device (10) in dependence on a motion of the moving device (130), such that energy for commands or other operations is provided to the switch device (10). The moving device (130) is configured to be repeatedly repositioned in relation to a defined zero position, as long as it has kinetic energy, in order to provide kinetic energy which can be converted in electric energy by the energy harvester (132, 140, 140a). Such an electromechanical device for generating energy can ensure wireless operation of the switch device (10) without the need of batteries or any other kind of power supply.

Abstract: A patient interface assembly includes a support member having a central support portion and a pair of cheek mount supports coupled to the central portion. Each cheek mount support applies a force on or on a side of a user's cheekbone. A seal member is coupled to the support portion and seals against the user. An additional nasal support member is provided that includes a first lateral side member operatively coupled to the central support portion and arranged to be disposed along a first side of a user's nose, and a second lateral side member also operatively coupled the central support portion and arranged to be disposed along a second side of a user's nose. At least a portion of the first lateral side member and the second lateral side member is rigid or semi rigid.

Abstract: The present invention relates to a very simple and robust wireless batteryless device (100) for harvesting energy. The actuation upon button pressure/release results in a rotation of a first member (1) around its central axis (11) leading to a move of an element (3), which is loosely fixed at the first member (1) from a pivot point (14), and a rotation around the central axis (11) of the second member (2) to which a generator axis of an energy harvester is coupled, the rotation axis of the generator being coincident with the central axis (11). Upon full pressure/release, the element (3) is forced to rotate around the pivot point (14), allowing a vertically raised pin (22) of the second member (2) to disengage a recessed area (31, 32) at each end of a slot (30) of the element (3) and the second member (2) to rotate to its rest position.

Abstract: The invention defines a mechanical fuse (20) for a neck cord (30). The mechanical fuse opens the neck cord when a pulling force component in a predetermined direction (70) exceeds a predetermined fuse force at which a rupture element (50) included in the mechanical fuse is designed to break. The rupture element has a break plane (51) at which breakage will occur when the pulling force component causes the stress in the break plane to exceed the value determined by said fuse force. The mechanical fuse further comprises a housing (60, 61, 62) that is arranged to guide the component of the pulling force in said predetermined direction (70) to the break plane whereas the transfer of a force component having another direction is suppressed.

Abstract: When a subject is being positioned in a diagnostic imager for a diagnostic scan, a subject support (26) often picks up an accessory carriage (24) along the way without stopping or reducing velocity. To reduce stresses on the subject support (26), accessory carriage (24) and on the subject themselves, an apparatus and method are provided for gradually accelerating the accessory carriage (26) to the speed of the subject support (26). A camming surface (60) engages a pin (54b) of a snap block (52) causing translational motion to be converted into rotational motion, spreading the acceleration of the accessory carriage (24) over a distance (d-d1).
