Abstract: Apparatus and methods are provided for automatically interrogating a tagged object using radio frequency identification (RFID) when the object is moved. In one embodiment, a worker is outfitted with a wearable RFID system including an RF antenna, an RFID reader, and a holder to hold the antenna and reader during operation. The system is worn by the worker while the worker moves objects from one place to another. When the worker moves an object with an attached RFID tag, the antenna automatically begins scanning for signals from the object's RFID tag. When a RF signal is received by the antenna, the RFID reader collects the signal and transmits it to a host system which processes the signal to obtain information related to the object to which the RFID tag is attached.

Abstract: An imaging device mounting apparatus providing three-point stabilization is described.

Abstract: A method and apparatus for tracking transported items using RFID tags are provided. A tote for transporting RFID tagged items includes a body capable of enclosing one or more RFID tagged items. RF reflective and/or absorbent material is positioned to inhibit RF signals from reaching the enclosed RFID tagged items from outside the body. A portion of a wall of the tote or a sleeve for insertion into the tote can be free of reflective and/or absorbent material to allow RF signals to be sent into, and exit, the tote. The RF reflective and/or absorbent material can be provided with or without texture.

Abstract: The present invention encompasses a lighting apparatus comprising a rigid housing and a mounting handle coupled to the housing. The housing defines a channel into which a plurality of light sockets may be installed. The mounting handle defines an opening through which mounting hardware may extend to support the lighting apparatus on a building. The lighting apparatus may also have an installation handle coupled to the housing, with the installation handle defining an opening through which an installation tool may extend to assist in lifting the lighting apparatus during installation. In one embodiment, the present invention also includes a face plate coupled to the housing and positioned in front of the areas where the light sockets will extend. The face plate defines a plurality of openings that may be shaped in a decorative design or as letters.

Abstract: A gearless locking differential includes clutch housings containing V-shaped slots that cooperate with a cross pin to disconnect from the differential drive shaft an overrunning driven shaft, characterized in that the wall surfaces that define the V-slots extend parallel with the axis of rotation of the differential housing, and the cross pin has tapered convergent end portions. The frictions packs that releasably connect the side gears to the clutch members include annular friction plates that are arranged between pairs of reaction plates and include polygonal internal surfaces that slidably and non-rotatably engage a corresponding polygonal circumferential surface on the associated side gear. The locking lug and locking slot that cooperate to provided limited angular relative displacement between the clutch housings each have parallel side walls. As a consequence of the invention, the machining and finishing of the components of the differential are achieved in a simplified cost-effective manner.

Abstract: An improved paddle apparatus for kayaks, canoes, or like water craft having a plurality of hand grips mounted to allow dynamic rotation relative to the paddle shaft to allow the wrist to remain in a natural position while paddling and still allow full power to be transferred from the blade into the water. Also a means of paddling whereby the operator can paddle with greater power and control on either side of the watercraft without breaking either handgrip. A further improvement includes using the handgrip in the position perpendicular to the paddle shaft to determine the blade position by feel and steer with greater torque. An alternative embodiment includes rotation of the grip itself, further reducing the twisting of the wrists and other joints.

Abstract: Systems and methods are provided for processing and analyzing signals reflecting, physiologic processes and events in a monitored subject, especially cardio-pulmonary signals. The input signals are analyzed by in a physiological domain by creating structured data representing the physiological events reflected in the signals. Preferably, first, primitive event objects are created representing physiologically-significant portions of these input signals; second, the primitive event objects are grouped into primary event objects representing actual physiologic processes and events. Next, all objects are stored in databases, and organized in containers for efficient searching. Information may be retrieved by creating view objects which associate physiologic event objects having selected properties specified directly in physiological terms.

Abstract: A rear closure assembly for use with a vehicle includes a door having first and second handles for pivoting the door about first and second vertical pivot axes. Latches on the door are engageable with strikers on the vehicle. The latches and strikers form the first and second vertical pivot axes. The latches are disengageable by the handles to selectively pivot the door about one of the vertical pivot axes.

Abstract: An agitator assembly for agitating a substance in a container comprises a container, a magnetic drive device, and an agitator element. The magnetic drive device is disposed adjacent to an outside surface of a lateral wall of the container. The agitator element is disposed in the container and is magnetically coupled with the magnetic drive device for self-supported rotation about a central longitudinal axis. The agitator element includes an agitator body, a first magnet mounted at the agitator body, and a second magnet mounted at the agitator body and circumferentially spaced from the first magnet. The agitator element substantially centered about the central longitudinal axis and supported at a substantially constant axial position within the container by the magnetic drive device.

Abstract: An installable load shoulder is used with a wellhead to support a tubing hanger by which tubing is suspended in a well bore, "tubing" being inclusive of any tubular product such as a string of tubing or casing as used in drilling and completing oil or gas wells, the wellhead having a vertical opening therethrough and in the wall defining the opening an internal circumferential groove, the groove having an inwardly sloped bottom frusto-conical circumferential surface and the tubing hanger having an external circumferential surface dimensioned to be slidably received in the wellhead vertical opening and having an external circumferential area defined in part by a frusto-conical circumferential surface. The load shoulder is of toroidal shape, has a split therein, has an internal circumferential surface defined in part by an inwardly sloped upper frusto-conical shaped surface and an external circumferential surface defined in part by a lower outwardly sloped frusto-conical shaped surface.

Abstract: The bore of a bearing bush for a gear pump has a first recess located in a zone of load concentration in the bore, the first recess being supplied with a fluid under pressure. A second recess in the bore is located wholly outside the zone in which concentrated loads occur and acts as a reservoir for fluid, to prevent cavitation within the bore as a result of low pressures caused by radical movements of a shaft within the bush. A passage connects the second recess with a zone of lower pressure within the pump.

Abstract: A spline drive arrangement comprises an internally-splined gear in driving engagement with two externally-splined shafts. An axial projection 18 on the shaft lies within a bore in the shaft, and elastomeric rings frictionally engage the projection and the bore and inhibit relative movement between these parts. Relative axial movement is also inhibited by a liquid-filled space defined with the bore by the end of the projection, liquid flow to and from this space being constrained to flow through a restricted passage.

Abstract: A spline drive arrangement has two externally-splined shafts, which engage an internally-splined gear. An extension on the shaft is a relatively close fit in a bush which lines a bore in the shaft. The drive arrangement is maintained full of liquid which can enter and leave a space in the bore by way of restricted passages and a clearance zone between the extension and bush. Damping and viscous drag of the fluid tends to prevent relative movement, between the splines of the shaft and gear, which may occur if the torque load on the shaft is low.
