Abstract: A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.

Abstract: A method of setting a bearing within a housing and a bearing cavity is disclosed. The method includes threadably advancing a threaded bushing by rotating the threaded bushing in a first rotational direction and identifying a point of contact when the threaded bushing initially contacts the bearing. Subsequently, the threaded bushing is rotated in the first rotational direction by a first predetermined rotational amount to further threadably advance in the first rotational direction so that the threaded bushing exerts a target preload on the bearing, or the threaded bushing is rotated in a second rotational direction by a second predetermined rotational amount to threadably advance the threaded bushing in a second axial direction that is opposite the first axial direction to create a target clearance between the threaded bushing and the bearing, or the threaded bushing is not further rotated to cause line-contact between the threaded bushing and the bearing.

Abstract: Methods, systems, and computer program products verify compatibility between a document to be published for access via a server and capabilities of the server to support features of the document. A method involves receiving a document, scanning the document for features, comparing the features to the capabilities of the server, and determining whether the capabilities of the server support the features of the document. The method also involves generating an incompatibility notice for a feature of the document when the feature is not supported by the capabilities of the server.

Abstract: A ground fault circuit for a poly-phase circuit is disclosed. The ground fault circuit provides a plurality of current limiting impedance paths from a neutral of the poly-phase circuit to ground. A sensing circuit monitors the paths and may indicate failure of one of the paths. The sensing circuit, may, for example sense the net impedance of the plurality of paths and note an alarm in the event of an increased or decreased impedance, indicative of an open or short circuit along either path.

Abstract: An improved power resistor includes a resistive element extending between a first electrical connection terminal and a second electrical connection terminal. The resistive element has a plurality of first insulating regions, arranged along its length extending generally parallel to each other in a first row. The resistive element further has a plurality of second insulating regions arranged generally parallel to each other in a second row. The first and second rows are further arranged generally parallel to each other so that each of the second insulating regions extends between two of the first insulating regions. The first and second insulating regions thereby define a tortuous current path from the first terminal to the second terminal. This tortuous path creates a current path between the terminals having increased resistance. The insulating regions are preferably interleaved chevrons and are preferably formed by stamping out portions of a resistive slab, made of steel or the like.

The device has four primary mirrors oriented ninety degrees from one to the next about the vertical axis. The primary mirrors are tilted about respective horizontal axes relative to the vertical axis and adapted to receive and reflect a laser light beam as each primary mirror moves successively through a portion of each rotational cycle of the optical device. The optical arrangement also includes a multiplicity of secondary mirrors disposed in stationary positions relative to one another and to each of the primary mirrors as they move successively through the rotational cycle portion.

Abstract: A compact counter-type bar code scanner produces a "five-apparent-source" scan geometry within an optimum scan volume above the deck of the bar code reader, with a total scanner housing height of less than 13 centimeters, and preferably about 11.5 centimeters. The optics are maximized to achieve approximately the same bar code reading efficiency and reliability as in previous much deeper bar code scanners producing similar scan geometry by reflecting the scanned beam off three surfaces, the last of which is horizontal.

Abstract: A four-bar alignment adjustment mechanism with elastic hinges enables the mirrors of a gas laser to be very finely tuned with accuracy. A 50.degree. rotation of the fine-adjust knob deflects the mechanism to produce a 1% drop in power from maximum. The system has little backlash and does not use an extra-fine screw to directly move the mirror plate.
