Abstract: An adaptive, any-fuel reciprocating engine using sensor feedback integration of high-speed optical sensors with real-time control loops to adaptively manage the electronic actuation schemes over a range of engine loads and fuels. The engine uses one or more optical sensors to collect specific types of gas property data via a spectroscopic technique to adaptively control various components within the engine.

Abstract: Disclosed is a field effect transistor integrated within an associated transistor area, the field effect transistor comprising transistor contacts having a contact configuration of interleaved contact fingers including outer drain contact fingers located at opposite edges of the transistor area.

Abstract: A portable cooler has a thermally isolating outer shell defining an internal compartment for holding contents to be kept cool, such as, for example, food, drinks and temperature-sensitive medicine. The portable cooler has a door connected to the outer shell for providing unrestricted access to the internal compartment. The portable cooler may have a shelf for holding a cold gel pack to help keep the contents cool. The cooler may also have a plurality of dividers (that are optionally reconfigurable) for defining variously sized storage spaces for the contents. The cooler may have an aesthetically pleasing curved outer shell and an adjustable shoulder strap so that the cooler can be carried on a person's shoulder. Because the cooler is easy and comfortable to carry and because its large swing-open door provides full and quick access to its contents, this cooler is more ergonomic and aesthetic than traditional designs.

Abstract: An adjustable table has a pair of substantially parallel legs pivotally mounted to a base and extending upwardly to connect pivotally to a table top support to thus enable the table top support to cant between a forward-leaning posture and a rearward-leaning posture. A table top is rotationally mounted to the table top support to enable the table top to rotate relative to the base. The table top can have an upper panel that extends horizontally relative to a lower panel. The table top can also have a tilting mechanism to tilt the upper panel of the table top relative to the lower panel. Telescopic legs can furthermore provide height adjustment. This table can adopt multiple configurations and postures, thus providing an ergonomic, adjustable table for a variety of uses and applications.

Abstract: A propulsion unit for a wheelchair wheel with a track. The propulsion unit comprising a body having a front portion, a rear portion and a handle, at least three rollers pivotally mounted to the body, front and rear friction elements positioned in the front and rear portions of the body respectively. When the handle is pressed forward the wheel is propelled forward and when the handle is pressed rearward the wheel is propelled rearward.

Abstract: A propulsion unit for a wheelchair wherein the wheelchair has a pair of large diameter wheels of the type having a circular handrail. The propulsion unit comprising a body having a front portion, a rear portion and a handle, at least three rollers pivotally mounted to said body, front and rear friction elements positioned in said front and rear portions of said body respectively. When the handle is pressed forward the wheel is propelled forward and when the handle is pressed rearward the wheel is propelled rearward.

Abstract: A multiple-frequency local oscillator for providing an LO signal at one of a multiple of predetermined resonant frequencies associated with a number of resonators is disclosed. It includes a number of LO input ports for coupling to a plurality of resonators, respectively, each resonator having a predetermined resonant frequency; the local oscillator is controlled to selectively provide at its LO output port an output LO signal at any one of the resonant frequencies.

Abstract: Acrylic compositions filled with alumina trihydrate with the mixed ester reaction product of propylene glycol methacrylate and phosphorus pentoxide have superior mechanical properties and ease of manufacture. In such acrylic compositions, the ester reaction product imparts superior properties by acting as a very effective coupling agent between the alumina trihydrate filler and the acrylic matrix.

Abstract: A tilting seat having a base for supporting the seat on the floor and a stem extending upwardly from the base, either integrally or separably from the base, the seat being arranged such that it tilts about a tilting axis passing through the base such that a user can tilt the seat forward when in a working position. The base may be a turntable.

Abstract: A system for supplying plastics material to a plastics working machine, such as a blow moulding machine comprising automatic means for removing waste from a plastics working machine, a conveyor for feeding the waste to a comminuting machine, a hopper for comminuted plastics waste, and a conveying mechanism for mixing and conveying the plastics waste and fresh plastics material to a further hopper that is arranged to supply the inlet of the plastics working machine.
