  • Patent number: 9383777
    Abstract: A computer includes a lid defining a lower edge. A hinge is connected to the lid along the lower edge. The computer further includes a base having an upper surface and a keyboard disposed on the upper surface and defining a back edge. A mounting assembly is connected with the base between the back edge and the keyboard. The mounting assembly has an attachment feature that moves along a translational path in a direction between the back edge and the keyboard in a manner that is constrained to rotation thereof. The hinge is rotatably connected to the lid to be rotatable with respect to the base. The hinge is rotatably affixed with the attachment feature such that rotation of the lid drives rotation of the attachment feature, which drives the movement of the attachment feature along the translational path, moving the lower edge of the therewith.

  • Publication number: 20160094107
    Abstract: A portable apparatus if provided for generating electrical energy. The apparatus has an electrical energy-generating device for generating electricity in response to input mechanical action, and a gravity powered drive for supplying the said mechanical action to the electricity-generating device by the descent of a suspended mass under the force of gravity. A protection system is provided to prevent a drive force, experienced by the electrical energy-generating device due to the input mechanical action, from exceeding a predetermined threshold as a result of an overload condition. The protection system may perform the dual function of physically protecting the electrical energy-generating device whilst also providing clear feedback to the user that the apparatus is subjected to an undesirable overload condition.

  • Patent number: 9193369
    Abstract: The handling properties of two-wheeled trolleys may be materially improved by arranging for the freely rotatable wheels (1, 2) to be able to move to a certain extent relative to the frame or load-receiving container portions (3, 4, 5) of the trolley in a direction parallel to the direction of travel of the trolley. This can be achieved by mounting the trolley wheels (1, 2) so that they, and the axles (32) on which they are mounted for free rotation, can, preferably independently, swivel about a horizontal axis displaced from (and lower than) the level at which the wheels are mounted on their respective axles. The wheels are preferably set at a high positive camber angle. Letting the wheels swivel materially improves handling on rough terrain. The trolley is preferably foldable to save space when being transported or stored.

  • Patent number: 8950889
    Abstract: Gravity powered electrical energy generators, particularly for producing lighting is disclosed. The apparatus has a support frame (1, 30) in which a series of gears and a gear-driven generator (20) are mounted. The power to drive the most upstream gear (2) is provided by a weight suspended from a point to one side of the axis of rotation of gear (2). The drive gear of the furthest downstream gear has no teeth so that the final contact between the drive gear and the shaft of the generator (20) is frictional. The gear ratio of the final downstream gear is at least 25. When used for lighting, the apparatus may include one or more high brightness LEDs (40) mounted on the housing (30). By suitable choice of gear ratios, the device may produce thirty minutes of illumination while allowing a 10 kilogram weight to fall through a distance of 1.8 meters.

  • Patent number: 8899852
    Abstract: A keyboard comprises a plurality of keycap-bearing physically-discrete segments that are hingeably coupled to one another. When in a non-deployed configuration, the keycap-bearing physically-discrete segments are disposed on a back side of a corresponding housing such that the keys face outwardly away from that back side of the housing. When in a deployed configuration, the keycap-bearing physically-discrete segments are disposed substantially planar with respect to that same housing and face outwardly away from a front side of the apparatus.

  • Patent number: 8830667
    Abstract: A keyboard portion is configured to move (with respect to a housing) between a deployed position and a non-deployed position. A cover pivotally couples to the housing and is configured to at least partially cover the keyboard portion when the keyboard portion is in the non-deployed position and to reveal the keyboard portion when the keyboard portion is in the deployed position. By one approach the cover is configured to move the keyboard portion between the deployed position and the non-deployed position as the cover pivots with respect to the housing.

  • Patent number: 8724317
    Abstract: A housing has a front surface and a back surface. A keyboard and a corresponding bottom surface move between a non-deployed configuration and a deployed configuration. A tray slides in and out of the housing along one or more slots that are formed internal to the housing. This tray can include an internal surface having a first side that contacts the keyboard and an opposing second side that contacts the aforementioned bottom surface when the latter components are non-deployed. When moving to the deployed configuration the keyboard and bottom surface first move substantially parallel to the housing and then move substantially perpendicular to the housing. Projections on these components can interact with corresponding tracks formed in the housing to direct at the least this perpendicular movement.
