A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB. Mass production of disposable hearing aids with large diaphragms and relatively low noise levels is thus possible using this invention.

An optical deflector includes a mirror having a reflective plane; a torsion bar extending outwardly from a side of said mirror; a support surrounding said mirror; a piezoelectric cantilever including a supporting body and a piezoelectric body formed on the supporting body, one end of said piezoelectric cantilever being connected to said torsion bar, the other end of the piezoelectric cantilever being connected to said support, said piezoelectric cantilever, upon application of a driving voltage to the piezoelectric body, exhibiting a bending deformation due to piezoelectricity so as to rotate said torsion bar, thereby rotarily driving said mirror through said torsion bar; and an impact attenuator connected to said support, the impact attenuator being disposed in a gap between said mirror and said support.

A scroll compressor has a biasing chamber which contains a pressurized fluid. The pressurized fluid within the chamber biases the two scroll members together. A rotatable ring is attached to one of the scroll members to open and close a passage leading to this biasing chamber. When the ring opens the passage in one embodiment, this releases the pressurized fluid to remove the load, biasing the two scroll members together. When the biasing load is removed, the two scroll members separate, creating a leakage path between discharge and suction to reduce the capacity of the scroll compressor. When the ring opens the passage in another embodiment, a delayed suction passage is opened to reduce the capacity of the compressor.

Ball bats and methods of making the same are disclosed whereby the handle and barrel members are separate structural components, and whereby the handle member is of sufficient length to extend through the hollow barrel member. The handle member is connected to the barrel member at its proximal and distal ends by proximal and distal connectors. The connection between the handle member at the proximal end of the barrel member is by means of an elastomeric proximal connector. The connection between the handle member and the distal end of the barrel member is accomplished by means of a rigid distal connector. The rigid connection of the handle member's distal end to the distal end of the barrel member and the elastomeric (flexible) connection between the handle member and the proximal end of the barrel thereby allows the handle member to flex substantially across its entire length during ball impact thereby improving ball speed and distance off the bat when struck.

An area-efficient capacitor-free low-dropout regulator based on a current-feedback frequency compensation technique is disclosed. An implementation of a current feedback block with a single compensation capacitor is used to enable capacitance reduction. The resultant low-dropout regulator does not generally require an off-chip capacitor for stability and is particularly useful for system-on-chip applications.

The invention involves orienting the metal laminations that form a stator core end in such a way so as to reduce eddy current losses in the finger portions of the metal laminations. The metal laminations are positioned so that the grain orientation is parallel to the magnetic flux lines generated in the finger portions.

An improved cantilever beam optical switch methodology which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a cantilever beam platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alterative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

A gas burner head with extra simmer capabilities, a burner base assembly and combinations thereof are disclosed. A gas burner head having one or a multiple fuel/air mixture exit ports with a simmer flange located above the ports and extending beyond the port exit by a predetermined distance allows the flame/fuel-air mixture from a given port to be fully or partially covered from above at a desired flame height or fuel-air mixture setting. The burner head can be a single or multiple piece assembly and can be used as part of a complete system or as an added-on component to an existing burner system. A burner base assembly has a burner base plate, a venturi and an orifice enclosure that creates a means to supply the required gas for combustion and also enables the burner head to be fully sealed. The venturi can be built-in as part of the burner base plate or made as a separate component and assembled through the burner base plate to create a sealed path. The orifice enclosure houses the gas injector orifice and can be installed in a separate compartment partitioned from the burner base plate by a sheet of metal (or partition plate) or in an enclosed area or plenum. Both the burner base plate/venturi combination and the orifice enclose may be securely attached to each other to maintain a predetermined distance between the gas orifice and the venturi inlet to allow a predetermined amount of primary air and gas mixture to be injected through the venturi into the burner head to create proper combustion. The burner base plate may be installed in a slightly raised position relative to the partition plate and/or orifice enclosure to create an air gap and the path through which primary air flows. A secondary source of primary air may be supplied through openings located around the orifice enclosure. The burner base assembly can be a single or multiple piece assembly and can be used as part of a complete system or as an added-on component to an existing burner system. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

A diamond composite heat spreader having a variable thermal conductivity gradient can improve control of heat transfer based on a specific application. A diamond-containing region of the heat spreader can contain diamond particles such that the diamond concentration and/or the diamond particle size a varied to produce a desired thermal conductivity gradient. Regions proximate to a heat source can have a higher thermal conductivity than regions further away from the heat source. Thin diamond films can also be used in conjunction with the particulate diamond in order to provide a region of maximum thermal conductivity adjacent a heat source. By providing a variable thermal conductivity gradient, more expensive materials such as diamond film and larger diamond particles can be selectively used in regions closer to a heat source, while allowing for cheaper smaller diamond particles and materials to be used farther away from the heat source where thermal conductivity can be lower without sacrificing overall performance.
