摘要:
An engine and associated methods are disclosed. An engine in accordance with the present invention comprises a housing defining a cavity and a slidable member disposed in the cavity. The slidable member is preferably configured to form one or more combustion chambers, and the slidable member adapted to slide back and fourth relative to the housing in a cycle. One or more intake ports are provided for selectively providing fuel to the one or more combustion chambers during selected timed during the cycle. One or more exhaust ports are provided for selectively venting exhaust from the one or more combustion chambers during selected times during the cycle. The intake and exhaust ports are preferably disposed so that intake and exhaust flows are in the same direction (e.g. uniflow).

A more efficient solid-state light emitting device in which phosphors excited by radiation produce visible light. The efficiency is increased by, for example, providing a reflector adjacent to the phosphor layer for reflecting at least some of the radiation that passes through the phosphor, back into the phosphor. The reflector may also reflect at least some of the visible light that is emitted by the phosphor toward a designated light output. Alternatively, or in addition to, the lateral edges of the active region of the radiation source can be at least partially surrounded by a visible light emitting phosphor and a reflector. This allows more of the radiation to interact, and thus excite, the phosphor material, making the device more efficient. The reflector also may reduce optical and radiation cross talk between adjacent light emitting devices.

A knocking-based, micro-combustion engine constructed in three layers of micromachined material. Two outer layers contain means for directing gases and fuels into and out of vents in a middle layer. The middle layer has machined in it two, linear, free pistons with or without integral air springs, and vents for directing gases and fuels into and out of a combustion chamber. A high compression ratio is achieved. The engine can be constructed with means to generate electrical energy.

The first conductive segment is electrically connected to one end of the first through-hole connector, the other end of the first through-hole connector is electrically connected to one end of the second through-hole connector via the first conductive segment, and the other end of the second through-hole connector is electrically connected to the second conductive segment.
摘要:
A micro-fluidic osmotic pump capable of delivering a desired fluid at a predetermined destination comprising an inside fluid reservoir housing a compressible sac, a surrounding compartment having an external surface made up of a semi-permeable membrane and a fluid duct. The inside fluid reservoir houses a compressible sac containing a predetermined amount of a fluid that is desired to be pumped to a predetermined destination. The surrounding compartment holds a desired osmotic agent and its saturated solution in the remaining volume thereof. The surrounding compartment has an outer surface made up of a semi-permeable membrane that allows a predetermined second external fluid to permeate into the surrounding compartment. The fluid duct is substantially housed within the inside fluid reservoir and runs through openings and respectively provided through the inside fluid reservoir and the surrounding compartment.
