Abstract: Systems and methods for MEMS devices are disclosed. A microelectromechanical system (MEMS) device includes a substrate, and a MEMS structure supported by the substrate. The MEMS structure includes a first layer of a first material comprising a titanium aluminum alloy. The MEMS structure furth includes an aluminum layer on the first layer.

Abstract: A connectivity has a first network (25) of signal-links interconnecting a large plurality of address-bearing, computing cells (20 and 22). Some of the links are selectable according to addresses hierarchically ordered along a recursive curve. Most of the address-designated links that form the network are switchably operable between cells such that a first selectable set of cells along one segment of the recursive curve form signal-routes to a second selectable set of cells, along a second segment. For receipt of instructions and for synchronisation, some segments have a switchable signal-path from one controlling cell of that segment. A second network (23) has signal-links interconnecting a plurality of processing cells (19 and 21) some of which control the loading of data into cells of the first network.

Abstract: An organic Rankine engine used to power a vehicle is provided with a quick-start system of pumps, electric heaters or pistons to generate a pressure differential across the motor, prior to the engine reaching operating conditions.

Abstract: A squeegee mount and assembly which cooperate to permit both pivotal and linear motion of the squeegee assembly relative to the machine frame. To avoid contact with a stationary object, the squeegee assembly can be both pivoted and linearly moved relative to the surface maintenance machine, thereby preventing damage to the squeegee assembly and/or the surface maintenance machine. The squeegee mounting assembly includes a mounting arm, a subframe, a return spring coupled between the subframe and the frame, and a stop. A squeegee assembly comprised of a squeegee blade, an arcuate squeegee blade holder, and a link which couples the blade holder to the squeegee mounting assembly. A guard rail is also coupled to one end of the blade holder and rotatively coupled along another end to the frame.

Abstract: Airborne units (2) acquire images as electronic signals either directly or indirectly from first ground based units (2a) and transmit them by broad band radio to second ground based units (3, 4), either directly or indirectly via second airborne units (1), which units (3, 4) record the received image signals for a period of time sufficient to permit a section of the received image to be selected by narrow bandwidth means (5, 6).

Abstract: A device and method of use for cleaning a ground surface with pressurized cleaning solution is disclosed. The device includes a transportable deck having at least a first chamber and a second chamber, each first and second chamber being in open communication with the surface, said first chamber having a nozzle for directing a pressurized cleaning solution toward the ground surface, and said second chamber having a vacuum outlet for removing cleaning solution and debris from the surface. Additional embodiments of the present invention may include a solution recycling system for reusing recovered solution.

Abstract: In one embodiment, the subject invention includes a squeegee mount assembly and a squeegee assembly which cooperate to permit both pivotal and linear motion of the squeegee assembly relative to the machine frame. To avoid contact with a stationary object, the squeegee assembly can be both pivoted and linearly moved to fully retract it within the boundary of a surface maintenance machine, thereby preventing damage to the squeegee assembly and/or the surface maintenance machine. In one embodiment, the subject invention includes a squeegee mounting assembly slidably coupled to the frame of a surface maintenance machine to allow transversal movement of the squeegee mounting assembly relative to the frame. The squeegee mounting assembly includes a mounting arm, a subframe, a return spring coupled between the subframe and the frame, and a stop.

Abstract: A figurine replica of a person such as a player of a particular sport. The figurine replica has a front housing member replicating the front portion of a body of a person except for one limb member, a rear housing member secured to the front housing member and replicating the rear portion of the body of the person except for the limb member, and a replication of the limb member. The limb member has a spring component projecting therefrom and retained between the housing members such that the limb member can be moved by hand and the spring component returns the limb member to its original position. The spring and limb can be molded as a single unit, with the spring either in an elongate configuration for coiling upon assembly of the figurine replica or in an already-coiled configuration.

Abstract: A self-propelled toy vehicle suitable to be given away as a promotional item includes a body shell, having a rear opening or key hole to an internal propulsion mechanism that contains a compression spring. The tip of a separate, key-shaped actuator is insertible into the propulsion mechanism to distort the spring. The actuator also preferably includes a latch member that engages a complimentary capture member in the propulsion mechanism. The latch member is manually disengaged, propelling the body shell forward utilizing the opposing force of the compression spring. The promotional toy is fun and safe to use, and may be manufactured inexpensively.
