The RABBAT ELECTRIC HYBRID VEHICLES have no mechanical transmission of power, only ductile wires connecting various sections of the car.The multiplicity of capacitor/battery units makes it easier for the vehicle designer to position them around for cosmetic or actual mechanical need, for better handling and safety.A diode between the motor and battery ensures that there is never any backflow of current. The ultra-capacitor/battery units which are charged thru a plug-in or a pantograph from an external supply and by an internal engine/generator which could be H2/O2, liquid/gas, internal combustion/jet/rocket/explosive) running at a uniform most efficient rate without being affected by stops or starts, slowing or acceleration, from start to finish.In this vehicle there is no juggling between application of internal combustion energy and electrical energy. It is sequential: fuel to electricity to motor drive, all the time.The RABBAT BUS STOP where potential passengers wait for the bus, offers certain services and saves bus time by having customers purchase bus tokens or electronic tickets ahead of the bus arrival. Then they access the bus thru a turnstile. The RABBAT BUS STOP provides grid supplied electricity to the bus as soon as its railings make contact, during its wait, and until its railings lose contact with the external supply.

摘要:
Integrated micro-valve is formed to control fluid flow and pressure. The valve converts supplied energy to mechanical energy through a means for energy conversion resident above a flexible wall or membrane. In one embodiment a sealed cavity contains a fluid that expands and contracts as it is heated or cooled, thus causing the flexible wall to move. Movement of this wall or membrane is used to move a valve element and dynamically control the opening or closing of a valve port over a predetermined range. Additional means for stiffening are added to the membrane to improve performance.

A thermoelectric array, such as a thermocouple array, includes a pair of dissimilar conductors disposed adjacent to each other at a plurality of locations. A switch is provided which selectively electrically couples and decouples the conductors at each such location, and an effective thermoelectric element is formed at the location where a switch is closed. The switches may be easily controlled to ensure that only the switch at the desired location is closed to form an effective thermoelectric element. Switches may include MOSFET pairs in series or dual-gate MOSFETs, and arrays of such switched thermoelectric elements may be integrated and fabricated on a common semiconductor substrate.

摘要:
A force or pressure transducer is includes a substrate, a dielectric material disposed on the substrate, a spacing member disposed on the dielectric material, and a resilient element disposed on both the dielectric material and the spacing member. A portion of the resilient element is separated from the dielectric material, and another portion of the resilient element is in contact with the dielectric material. The contact area between the resilient element and the dielectric material varies in response to movement of the resilient element. Changes in the contact area alter the capacitance of the transducer, which can be measured through associated circuitry.
