The capacitor assembly comprises a center hole, at least one capacitor, a capacitor housing having at least one busbar, and a plurality of through holes in the capacitor housing. The capacitor assembly and the at least one PCBA are positioned inside the housing. The plurality of positioning pins pass through the through the plurality of through holes of the capacitor housing and the at least one PCBA and are connected to the housing.

Abstract: An illustrative example of the present disclosure provides a machine configured to form a composite structure. The machine includes a composite placement machine, measuring equipment, a tool path generator, and compaction equipment. The composite placement machine lays up composite plies. The measuring equipment measures surfaces of the composite plies to form measurements during layup of the composite plies. A computer includes a model of the composite plies for a structure. The tool path generator forms a modified tool path based upon a difference between the measurements and expected measurements for the composite plies in the model.

Abstract: A mobile travel information system and method are disclosed for providing a variety of travel-related information and services to a traveler via a personal electronic device. A custom application installed on the personal electronic device provides, for example, itinerary management, navigational assistance, local recommendations, driving condition alerts, etc. The system may interface with airline, hotel and car rental reservation systems and obtain data from a variety of sources, so as to function as a mobile personal concierge for a traveler.

Abstract: A system and method for detecting and remotely assessing a vehicle incident and dispatching assistance to a motorist. The system includes an in-car device for detecting vehicular incidents such as mechanical failures and collisions. The system transmits an incident notification to a remote monitoring station. A camera associated with the device transmits images to the station, where an operator can view and assess the nature of the incident, communicate by voice and/or video with the occupant of the vehicle via a cellular telephone connection, and dispatch assistance. Assistance may include sending a replacement vehicle.

Abstract: A virtual rent-a-car system and method with an in-car device and related systems and methods are disclosed for providing customer service interactions, tools, and entertainment to a vehicle rental customer. The functions of the in-car device include, for example, navigational assistance, local recommendations, driving condition alerts, itinerary management, vehicle comfort controls, and entertainment media play controls.

Abstract: Device, method, and computer program product for monitoring the social health of a persistent virtual environment. The disclosed technology monitors social interactions between subscribers of on-line entities who have interactions related to the persistent virtual environment.

Abstract: Device, method, and computer program product that provides a user interface for monitoring the social health of a persistent virtual environment. The disclosed technology allows a user to monitor and diagnose the health of the persistent virtual environment based on the social interactions between subscribers of on-line entities who have interactions related to the persistent virtual environment.

Abstract: A waterfall apparatus for producing an artificial waterfall having a waterfall apparatus including a chamber, an inlet for water into the waterfall apparatus, a primary outlet having an opening to allow water to flow out of the waterfall apparatus in a waterfall configuration, an attachment means for attaching the waterfall apparatus to a sidewall of a spa; and a removable baffle means located between the inlet and the outlet for more evenly distributing the water flowing out of the waterfall apparatus.

Abstract: A waterfall waterjet that can be attached to a spa, with at least one chamber, at least one primary outlet, at least one debris outlet that can be opened and closed, and a water source fluidly connected to the waterfall waterjet.

Abstract: A method for allowing access to data frames on an elevator communications bus includes (a) disconnecting a remote station 117 from the communication bus 24; (b) connecting the elevator communications bus 24 to the elevator communications bus analyzer 100; (c) providing the power, return, clock, and data signals on lines 46a, 46b, 48a, 48b from the elevator communications bus analyzer 100 to the remote station 117 previously disconnected; (d) connecting receive or transmit trigger lines 120, 122 from the elevator communications bus analyzer 100 to an oscilloscope 24; (e) selecting an address of a remote station; (f) connecting clock and data signals on lines 46a, 46b to the oscilloscope 124; and (g) switching the oscilloscope 124 to its differential mode to provide on an oscilloscope screen the difference between the clock and data signals (the signal on line 46b minus the signal on line 46a) for the address so that an elevator mechanic may see the data bits on the elevator communications bus.

Abstract: A method and apparatus are disclosed for converting the 35 mm image from a conventional fundus camera into a size suitable for recording by a conventional solid state CCD module. The CCD camera connects to the fundus camera using a bayonet attachment. The aerial image created by the fundus camera is received and transmitted through the CCD camera along a folded mirror optical path, and is reduced and aligned for detection by the CCD module. The optical path contains a pair of adjustable mirrors to allow compensation for variations in the focal lengths between various fundus cameras. An articulating mirror may be included to enable the user to pan across the aerial image while recording segmented views for reconstruction by an external computer into a composite, high resolution image.

Abstract: A process for the separation of a mineral acid from a common ion salt comprises a step of flowing a quantity of the mineral acid and salt in aqueous solution onto a strong base common ion form anion exchange resin bed whereon the mineral acid is retarded with respect to the salt. The salt is removed from the anion exchange resin. An interface cut of the mineral acid and the salt is recirculated from a bottom portion to a top portion of the anion exchange resin for further separation. A quantity of water is flowed through the anion exchange resin bed to elute the mineral acid therefrom. A portion of the elutant fluid is recycled to the top of the anion exchange resin bed.

Abstract: An adjustable louver blade assembly including a number of horizontally extending, movable louver blades (22). Each of the blades is formed in a generally hollow airfoil shaped cross section having a leading edge and a trailing edge. Trips (46,48) for inducing turbulent flow of the boundary layer are embossed on the blade surfaces. Reinforcing spacer ribbons (42) are frictionally secured within each blade to rigidize the blade.The pivotal axis of each blade is located so that the axis is forward of the center of aerodynamic force exerted on the blade for all attitudes of the blade between a closed position and a position about 60.degree. from the closed position. A control rod (26) is connected to each of the louver blades so that all of the blades can be simultaneously swung to any attitude between fully open and fully closed.
