Abstract: A vehicle hitching assistance system includes a controller executing an initial alignment process including searching for a trailer within a specified area of image data that is less than a total field of the image data in directions corresponding with both a longitudinal distance between the vehicle and the trailer and a lateral direction perpendicular to the longitudinal distance, presenting an indication to a driver of the vehicle to reposition the vehicle when the trailer is not identified within the specified area, and removing the indication when the trailer is identified within the specified area. The controller further executes an automated backing process upon identifying the trailer within the specified area, including identifying a coupler of the trailer and outputting a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler of the trailer during reversing.

Abstract: A laser can produce pulses of light energy to eject a volume of the tissue, and the energy can be delivered to a treatment site through a waveguide, such as a fiber optic waveguide. The incident laser energy can be absorbed within a volume of the target tissue with a tissue penetration depth and pulse direction such that the propagation of the energy from the tissue volume is inhibited and such that the target tissue within the volume reaches the spinodal threshold of decomposition and ejects the volume, for example without substantial damage to tissue adjacent the ejected volume.

Abstract: Disclosed herein is a method and system for producing a term association vector space on demand for a client given a document set in electronic form. The method extracts terms from the document set, stripping out words that do not convey meaning and adding important phrases within the context of the document set to the terms. Associations between terms are calculated, subjected to further analytical processes, and collected in a matrix, whose rows are vectors defining the vector space. Additional associational data can be added by matrix arithmetic, and documents can be rendered as further vectors in the space.

This Abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b).

Abstract: An improved lookup service is provided that allows for the dynamic addition and deletion of services. This lookup service allows for the addition and deletion of services automatically, without user intervention. As a result, clients of the lookup service may continue using the lookup service and its associated services while the updates occur. Additionally, the lookup service provides a notification mechanism that can be used by clients to receive a notification when the lookup service is updated. By receiving such a notification, clients can avoid attempting to access a service that is no longer available and can make use of new services as soon as they are added to the lookup service.

Abstract: A polyurea-polymer formulation suitable for preparing a molded polyurea polymer includes a polyisocyanate, an isocyanate-reactive material, and a fatty-acid ester. The fatty-acid ester is present in an amount effective for providing a molded polyurea polymer prepared from the formulation with blister resistance such that when the molded polyurea polymer is exposed to moisture and a temperature of at least about 350° F. (177° C.), the molded polyurea polymer is substantially free of blisters. A fatty-acid ester suitable for use with these formulations can be natural or synthetic, and one example includes jojoba oil. A polyurea-polymer formulation can also include other components known to be useful with polyurea polymers such as fillers, catalysts, surfactants, and polyepoxides. A molded polyurea polymer can be prepared from a polyurea-polymer formulation. One method suitable for preparing a molded polyurea polymer includes reaction injection molding.

Abstract: The protocol for controlling a network is encapsulated within the token circulated through the token ring network. Each computer in the network that receives the token examines the token and implements the network protocol specified in the token. In this manner, the protocol of the network can be easily changed, and automatically promulgated throughout the network.

Abstract: A replaceable development station is provided for use with an electrostatographic machine in which a toner monitor is automatically calibrated when a fresh development station is loaded into the machine. The detected toner concentration in the development station is used by the monitor as a reference signal against which future readings are compared. The reference signal is reset upon machine power-up correspond to the detected toner concentration in the development station, but only when there is a fresh development station in the machine. The development station provides for indicating when the reference signal has previously been set for the developer mix. The reference value would not be reset upon other than the first time the machine is powered up with a particular development station. The indicating means is preferably a frangible member such as an electrical fuse.

Abstract: A toner monitor in an electrostatographic machine is automatically calibrated when a new replaceable development station is loaded into the machine. The detected toner concentration in the development station is used by the monitor as a reference signal against which future readings are compared. The reference signal is reset upon machine power-up to correspond to the detected toner concentration in the development station, but only when there is a fresh development station in the machine. Resetting the reference signal only when there is a fresh development station prevents erroneous reference signals which would result if the developer mix concentration was other than perfect at power-down.

Abstract: An electrographic apparatus has a transparent photoconductor on which visible images are formed by applying toner to a latent electrostatic image. The toned image is subsequently transferred to a copy sheet and fused to the sheet. A post-development erase lamp is located on one side of the photoconductor. The density of toned images on the photoconductor is measured by light rays from the erase lamp traveling through the photoconductor and a toned control image thereon to a photodetector on the opposite side of the photoconductor. This eliminates the need for special lamps used only for measuring the density of toned control images.

Abstract: In a floor covering a layer of resilient material is bonded to the bottom of an upper layer and reinforcement is provided associated with or adjacent the bottom surface of the resilient material, whereby the floor covering can be secured to a floor by an adhesive, but can subsequently be peeled off the floor. An important embodiment is a carpet having a foam rubber-like underlay bonded to the carpet back and a mesh of plastic material positioned on the carpet back. Generally, the covering may be laid on a floor by laying the reinforcement mesh or the like on a floor, spraying or otherwise distributing adhesive material and the laying of the covering to secure it by the adhesive.

Abstract: A solid state disconnect or isolating device for disconnecting a subscriber on his premises, replaces a relay with associated circuitry and items. It can be coupled with a surge protection device to provide disconnect signalling, plus loop testing if desired. The device comprises a normally "on" junction field effect transistor which acts as a pinch resistor.

Abstract: Apparatus for enveloping battery plates within porous separators and for feeding a separator sheet to form a fold at the approximate midpoint of the separator, simultaneously positioning a battery plate with an edge adjacent to the fold line, passing the plate and separator through rollers to press the separator against both sides of the battery plate, and passing the folded separator and enclosed battery plate through an ultrasonic sealing unit for sealing opposite edges of the separator to form an envelope. The apparatus includes a separator sheet dispenser for dispensing individual separator sheets into an elongated passageway. The end of the passageway is blocked so that a separator reaching the stopping point buckles to form a fold at the approximate midpoint of the separator.
