Abstract: An infrared emitter is formed having a reduced thermal mass and increased thermal conductivity to effectively deliver and dissipate heat from a heating element that emits electromagnetic radiation. The improved thermal dynamic process may enhance one or both of power consumption and/or longevity.

Abstract: An apparatus such as a wireless telephone and methods of using the apparatus are disclosed, the apparatus having a dual camera module. The dual camera module includes a flex interconnect on which a first image module and a second image module are attached, each image module adapted to capture images. The two image modules can be placed such that images can be captured in different directions; at different resolutions; at different times; independently or simultaneously; generating independent or composite data streams.

Abstract: A method according to one embodiment comprises detecting a change in a rotational velocity of a magnetic disk or a spindle coupled to the magnetic disk, the change being caused by head-disk contact. A method for detecting head-disk contact according to another embodiment comprises measuring a rotational velocity of a magnetic disk or a spindle coupled to the magnetic disk; detecting a change in the rotational velocity, the change being caused by head-disk contact; and correlating the change in rotational velocity with the head-disk contact.

Abstract: An automatic blade-retracting box cutter utility knife has a handle with ergonomic hand grip proportions for comfortable gripping and handling during repetitive cutting operations. A blade-actuating hand-grip lever is mounted on the housing for movement about a pivotal axis. A blade shuffle is mounted for longitudinal sliding reciprocal movement in the housing from a rear retracted end position in which the blade is wholly received in the housing, to a front extended end position in which the blade is extended forward from the housing. The blade shuttle is extended in response to gripping actuation of the hand-grip lever. Extension and retraction forces are transferred from the hand-grip lever to a compression spring and to the blade shuttle via a power transmission assembly that includes a torque plate that is mounted for clockwise and counterclockwise rotation on the housing. Top access to a working blade and a replacement blade stored on the shuttle is provided for blade loading and security.

Abstract: An oil well pumping apparatus for pumping oil from a well to a wellhead provides a tool body that is sized and shaped to be lowered into the production tubing string of the oil well. A working fluid is provided that can be pumped into the production tubing. A prime mover is provided for pumping the working fluid. A flow channel into the well bore enables the working fluid to be circulated from the prime mover via the production tubing to the tool body at a location in the well and then back to the wellhead area. A pumping mechanism is provided on the tool body, the pumping mechanism including first and second gerotors. The first gerotor is driven by the working fluid. The second gerotor is rotated by the first gerotor. The two gerotors are connected with a common shaft. The tool body has flow conveying portions that mix the working fluid and the produced oil as the oil is pumped.

Abstract: A vehicle includes a motion sensor and a control processor. The motion sensor optically detects motion of the vehicle with respect to an underlying surface. The motion sensor includes a variable focus imager. The control processor receives information from the motion sensor and calculates location of the vehicle, speed of the vehicle and/or acceleration of the vehicle.

Abstract: A gas measurement system of this invention includes a detector assembly having a beamsplitter adapted to separate infrared radiation into a first beam and a second beam and a mirror adapted to receive the first beam from the beamsplitter. The first and second beams are directed to first and second detectors that are disposed in a common plane. In one embodiment, the optical elements are provided on or in an optical block. In another embodiment, the gas measurement system includes a housing that contains an infrared absorption gas measurement assembly, a luminescence quenching gas measurement assembly, and a processor that is programmed to measure gas constituents of a gas flow based on an output of the infrared absorption gas measurement assembly and the luminescence quenching gas measurement assembly.

Abstract: A holster and belt clip assembly for a box cutter are disclosed. In the holstering system embodiment, a holster releasably retains the box cutter. The holster has a body substantially conforming to the shape of the box cutter, an open top end, and a closed bottom end. A lanyard secures the box cutter to the holster. A belt clip, which is releasably engaged with the holster, mounts the holster to a belt of an operator.

Abstract: A heater for a window of an optical gas sensor is provided. The heater may be positioned over a portion of the window or may form at least a portion of the window. Alternatively, the heater may be separate from the optical gas sensor and positionable over the window either in contact therewith or in close proximity thereto. In one embodiment, the heater is substantially transparent to the relevant wavelengths of electromagnetic radiation that are used in optical monitoring of respiratory gases, anesthetic agents, or the like. Alternatively, the heater may be configured so as to provide a substantially unobstructed optical pathway through the window. Optical gas sensors and complementary transducers that include the heater are also disclosed.

Abstract: The present invention relates to a method and apparatus for controlling static charges in a fluidized bed olefin polymerization reactor. Static charges which develop in the polymer products are measured and, if they fall outside a predetermined range, static charge control agents are introduced into the reactor. By controlling the static charges in the reactor, sheeting and drooling can be controlled.

Abstract: In accordance with the present invention a projectile sensor comprises a support means, a lens means and a photocell comprised of multiple parallel photosensitive elements interposed by one or more diagonal photosensitive elements on or of a substrate disposed so as to provide changes in their electrical response when objects passing linearly through the sensor's field of view form an image through a lens upon the photosensitive elements in sequence. In its simplest embodiment, the photosensitive elements of the sensor substantially form a forward or reversed English letter “N” shape, such that a projectile's image passing over the photosensitive elements produces a series of electrical responses, where the ratios of the times between such changes relate to the velocity and position of the object.

Abstract: A portable in-line scooter parking stand that can hold a single scooter in an upright parked position. The stand is a rigid base made of aluminum or plastic, which includes a centrally located tapered slot, sized to fit and grip an inserted scooter wheel. Deep longitudinal grooves in the sides of the tapered slot, dig into the rubber sides of an inserted front scooter wheel and hold the scooter firmly upright. Four rubber feet attached to the bottom of the base prevent slippage or sliding. The stand is lightweight, inexpensive, and will hold all in-line scooters with standard 100 mm wheels.

Abstract: A machine to cover filled, preformed trays of a wide variety of shapes or sizes with foil or other material which will remain folded, from rollstock. The machine is simple, with few change parts, rapidly changed. To be truly rotary enabling high speeds. To have the cover stock continuously feeding trays travelling as close together as the overlying foil will permit, the trays travelling horizontally with no sideways movement. The foil to be folded down and under in one continuous movement exactly to the outside shape of the tray's lip, with no distortion of the foil atop the tray and with the foil so well crimped that there is no possibility of liquid leakage. The machine to be either equipped with its own conveyor, or capable of being placed over an existing conveyor.
