Abstract: A junction box mountable on a roof surface, comprising a housing unit and an enclosing unit, the housing unit and the enclosing unit combining to form a waterproof assembly. The housing unit is mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in a bottom surface of the housing unit to create a waterproofing zone inside the housing unit. At least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

Abstract: A tuneable flat panel UV exposure system for screen printing is provided. The panel includes a plurality of UV LED chips where each chip is connected to multiple, independently controllable power sources and pulse width modulation circuits. The power sources allow an operator to control a plurality of different wavelength outputs independently for each UV LED in the panel.

Abstract: An indicator system is provided for ensuring proper registration of a frame. A plurality of stops for a registration system are electrically coupled to each other. When contact is made with a metal frame, a circuit is created and an indicator coupled to the circuit, such as a light, can be activated to show such contact.

Abstract: Disclosed herein are systems and methods for performing angled confocal spectroscopy. Angled confocal spectroscopy permits sensitive, non-invasive investigation of numerous analytes in a wide variety of samples, including tissues and bodily fluids. The methods and systems disclosed herein can be used to measure spectroscopic signatures of analytes within well-defined and very small regions of samples, while at the same time achieving superior rejection of signal contributions from analytes within the sample that do not fall within a volume of interest. Accordingly, measurements can be performed at comparatively high signal-to-noise ratios, and can provide information such as concentrations and distributions of sample analytes at high spatial resolution. By using cylindrically-focused illumination light, samples can be excited by a “sheet” of light, allowing spatial signal averaging and enhancing the stability and reproducibility of the measurements.

Abstract: A computer system linking two-year degree granting institutions (DGI's) with four-year host institutions and with a nationalized database and unified server environment that is designed to communicate with individual students. The participating DGI and host institution must first obtain each student's permission for the system's use of their data. As part of the RT system, students will also be given access to their educational records housed at a centralized data repository. The reverse transfer process implemented by the system will include, for the host school, a file intake process involving the steps of receiving a file via FTPS, performing file edits, and correction of file errors. Once corrected, the host school will approve the file and submit it via a user Interface where the file will then be merged into the centralized database. For that student, the system will then reference a pre-stored authorization matrix in order to identify which DGI's are authorized to view the host school data.

Abstract: A hardware/PLC logic combination which enables measurement of a plurality of analog voltage points (e.g., multiples of 8 points) on a single high speed PLC input without separate synchronization inputs or outputs. This is accomplished through the use of a multiplexer circuit [clock, binary counter, analog multiplexer, voltage to frequency converter], and a high speed counter function at the PLC. Synchronization between the PLC and circuit is through the detection of a fixed voltage on channel “one” of the circuit, which is set well above the typical range (e.g., 0-10V) of the remaining analog inputs.

Abstract: A NAS server runs a native filesystem application that manages the filesystem and also includes a virtualization component that allows third-party data processing applications to run on the NAS server substantially as though running on a separate server while allowing the applications to access filesystem information without use of the network and without the overhead of network protocols and related operating system processing. The virtualization component intercepts certain filesystem-related system calls made by the application and directs processing of those filesystem-related system calls (e.g., by the virtualization component or by the native filesystem application), bypassing certain operating system processes including those relating to network protocol processing.

Abstract: Systems and methods for securely ordering and transmitting educational records via the Internet are disclosed. A requestor orders educational records via a clearinghouse web site. An application services module receives the order and forwards it to a school over the Internet via a secure connector module. The secure connector module provides authentication, encryption, and validation services, and interfaces with an SIS operations module. The SIS operations module retrieves the requested records from the school's student information system (“SIS”). The educational records are transmitted back to the clearinghouse via the secure connector module. The requestor can then download the records from the clearinghouse via a secure web site.

Abstract: An apparatus and method for cooling air that utilizes a removable reservoir that may be filled with a consumable beverage or other cooled liquid or solid material. The bottom of the reservoir is made of a thermally conductive material that is placed within an air duct within a base unit that has a battery powered fan capable of drawing in warm air from outside of the base unit and cooling it by passing it over the thermally conductive material in a turbulent fashion and expelling it back into the surrounding environment. An expandable hose may also be included to direct the airflow in a desired direction or location. The unit may also include an alternative path for airflow such that the airflow may be heated. The unit may also be secured to an open air vehicle such as a golf cart to provide cooled or heated air for golf course patrons.

Abstract: One or more nodes of a data communication system is automatically switched between two or more possible node configurations, such as between a DTE configuration and a DCE configuration, until the presence of a carrier or similar indicator signal is sensed. Configuration devices include relays and electronic switches. Control devices preferably are microprocessor based. In one aspect, upon power up or other initiation, the microprocessor toggles an output control signal so as to repeatedly toggle a switch between, e.g., DTE and DCE positions and to terminate the toggling when a link indicator is detected.

Abstract: A “splash” hoop toy relating to the original “Hula Hoop” is constructed with “splash” holes around the circumference of the tube and filled with water. During play (rotating the hoop around the body of the user) the water streams out of the holes and splashes anyone in the vicinity of the “splash hoop”. The number of holes, the volume of water inside the hoop as well as the size and location of the holes determines who will get wet and how wet they will get.

Abstract: An X-ray scatter reduction grid includes a first layer having a plurality of cells. The cells have a perimeter formed of an X-ray absorbing material. The shape of the perimeters can vary, but a polygonal shape is preferred. The grid can also include other layers, each with their own cells. The cells of the subsequent other layers are larger than and offset from the cells of the prior layer. The increased size of the cells allows a primary ray passing through the center of a first layer cell to also pass through the center of a subsequent layer cell. This allows for a maximum of primary ray passthrough and a maximum of scatter absorption.

Abstract: A magazine for dispensing liner bags from a supply roll through an aperture in the bottom of a trash receptacle includes an upwardly open base having a horizontal cross-sectional shape adapted to receive the trash receptacle, a hinge for connecting the base to the trash receptacle along a horizontal pivot axis extending along one side of the base, whereby the receptacle can be tilted away from the base to provide access to the base. The base has a seat formed by an inwardly protruding flange to limit the depth of penetration of the trash receptacle into the magazine, so that it does not bear against or otherwise interfere with the liner bag supply. Two parallel dividers in the base form three compartments. The outer compartments are useful for storing addition supply rolls or supplies, while the central one contains the active supply roll.
