Abstract: Implementations relate to a moveable display system. In some implementations, a control unit includes a first support and a second support coupled to the first support. The second support is linearly translatable along a first axis in a first degree of freedom with respect to the first support, and at least a portion of the second support is linearly translatable along a second axis in a second degree of freedom with respect to the first support. The control unit includes a display unit rotatably coupled to the second support. The display unit is rotatable about a third axis in a third degree of freedom with respect to the second support, and the display unit includes a display device.

Abstract: Implementations relate to a moveable display unit on a track. In some implementations, a control unit includes a support linkage including a first support coupled to a second support, a track member coupled to a distal portion of the second support, and a display unit coupled to the track member. The display unit includes a display device. The display unit is linearly translatable in first and second degrees of freedom provided by the support linkage. The display unit is rotatable, with respect to the second support, about a tilt axis in a third degree of freedom defined by the track member.

Abstract: Disclosed herein is an underseat alarm which provides is a lightweight, self-contained device that can readily be installed on wheelchairs of various configurations. The disclosed underseat alarm provides notification to the caretaker when a wheelchair occupant leaves the wheelchair seat, allowing the caretaker to immediately attend to the occupant and minimize the possibility of injury to the occupant.

Abstract: A device (1) for acquiring cell samples by aspiration into an evacuated container (3) comprising: a front hollow needle portion (7) to be inserted into the body from which a sample is to be taken; a rear hollow needle portion (5) for communication with the evacuated container; a conduit (11) connecting the front needle portion (7) to the rear needle portion (5); and a normally closed pinch valve mechanism (6) to open and close the conduit; The valve mechanism (6) is manually operable by one hand and controls the application of negative pressure in the front needle portion (7). The conduit may comprise a flexible tube and the valve mechanism (6) may comprise releasable means (8) to pinch the flexible tube in a pressure-tight manner. The valve mechanism (6) may comprise a spring-biased push-button (8) operable by one digit of a user's hand.
