摘要:
In an embodiment of the present invention there is provided a micro-electromechanical (MEMS) accelerometer, including a substrate, a first sensor and a second sensor. The first sensor is configured to measure an acceleration along a first axis parallel to a plane of the substrate. The second sensor is configured to measure an acceleration along an axis perpendicular to the plane of the substrate. The second sensor comprises a first beam, a second beam and a single support structure. The single support structure supports the first and second beams relative to the substrate, wherein the first and second beams circumscribe the first sensor.

A fluid compression system includes a compressor unit that directs a flow of compressed fluid to a first heat exchanger. A second heat exchanger receives a flow of coolant. A blower produces a flow of ambient air that passes through the first heat exchanger and the second heat exchanger so as to direct cooling air through both heat exchangers. A variable speed motor is coupled to the motor in addition to a control system to vary the motor speed between a low speed and a high speed.

An embodiment of the present invention is a technique to integrate data for a source synchronous protocol. A delay generator generates at least an integrating strobe from a data strobe synchronizing a data having a data window using the source synchronous protocol. A pulse generator generates a pulse from the at least integrating strobe. An integrating receiver integrates the data over an integration window defined by the pulse. The integration window is within the data window.

摘要:
An implantable hearing aid transducer including a transducer housing, a driver, and an actuator movably connected to the transducer housing. The transducer driver includes at least one coil and one magnet. In one aspect of the present transducer, a seal is provided to seal transducer components that are located at a location other than at the movable connection between the actuator and the transducer housing. According to this aspect, the seal may be disposed around one of a magnet and a coil that is connectable to the actuator, to protect the same from body fluids. The other one of the magnet and the coil may include its own seal within the transducer housing.

A variable reluctance motor is provided having a linear relationship between an input current and an output force. According to one aspect of the invention, the motor comprises a stator, an armature, and at least one magnetic member to provide a biasing force on the armature. According to this characterization, the motor also includes a drive coil to generate an electromagnetic field in response to a current input. The electromagnetic field, in turn, moves the armature relative to the stator during motor operation.

A developer cartridge for containing a developer and for delivering the developer to a developer hopper of an electro-photographic machine. A developer containment portion includes a first portion having an at least partially closed volume configured to contain the developer and a second portion adjacent the first portion and having an opening configured to deliver the developer to the developer hopper. A sealing gasket is disposed adjacent the second portion of the developer containment portion and surrounds at least a portion of a circumference of the opening. A first cover is disposed adjacent the second portion of the developer containment portion and is positionable between an open position for delivery of the developer and a closed position for preventing delivery of the developer. The sealing gasket contacts the first cover to prevent undesired leakage of the developer therebetween.
摘要:
A powder spray booth includes a booth canopy wall arrangement to contain powder during a spraying operation; and a booth floor that is rotatable relative to the booth wall during a spraying operation. The floor can be rotated about an axis that is also the longitudinal axis of the spray booth. The booth may be generally cylindrical in shape with a round floor. The booth canopy and top are supported on a base frame separately from the floor. By this arrangement, the floor can be rotated relative to the booth canopy. A powder extraction apparatus in the form of a low pressure duct suspended off the floor draws up powder that has collected on the floor. The extraction duct is stationary with respect to the rotating floor during a spraying operation. The floor may also be translated along the axis of rotation between a first position in which the floor can rotate and a second position in which the floor is sealed against a lower edge of the booth canopy wall. The booth canopy and floor are made of composite materials that are very low in conductivity to minimize powder adhering to the floor and booth walls. The booth is thus easy to clean with a substantially shorter time period required for color change.
