Abstract: A fenestration unit including screen coil apparatus is provided by the invention. The fenestration unit includes a frame defining an opening. A sash—is slideably received by the opening of the frame. The fenestration unit includes a screen coil assembly attached to the sash. The screen coil assembly includes a screen having first and second edges, and a roll core, wherein the screen is capable of being coiled and uncoiled on the roll core. The fenestration unit further includes an edge support having first and second support members having at least a portion located between the frame and the sash, the first and second support members for fastening to the screen first and second edges.

Abstract: A cardiac monitoring system and, more particularly, a wireless electrocardiograph (ECG) system. The present invention detects electrical signals from a patient's heart and transmits the signals digitally to a remote base station via telemetry. The base station converts the digital signals back to an analog electrical signals that can be read by an ECG monitor.

Abstract: An apparatus for removing a protective cover from the green of a golf course and for placing a cover on the green mounts to the front of a maintenance tractor on either the bucket of the tractor or the three point hitch of the tractor. The frame of the apparatus has two hydraulic motors mounted thereto are controlled and powered by the hydraulic system of the tractor. By mounting the roller bar to couplings on the motor with lynch pins a wrapped cover can easily be removed from the apparatus for storage.

Abstract: A method of fabricating a display system includes bonding a silicon substrate to a second substrate with an insulating layer. The silicon substrate is thinned to form a thin film silicon-on-insulator (SOI) structure. A matrix display circuit is formed with the SOI structure. A light shield pattern is formed over regions of the matrix display circuit. A light source, the matrix display circuit and a magnifying lens are positioned within a display housing such that light from the light source is directed onto the display and an image on the display is magnified by the lens for viewing by a user.

Abstract: An automatic sample testing machine for testing samples stored in test cards. The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles.

Abstract: A reaction vessel for a nucleic acid amplification reaction has a first chamber containing an amplification reagent mix, a second chamber containing an amplification enzyme, and a fluid channel or chamber connecting the first and second chambers together. A fluid sample is introduced into the first chamber. After a denaturation and primer annealing process has occurred in the first chamber, the fluid channel is opened to allow the solution of the reagent and fluid sample to flow into the second chamber. The second chamber is maintained at an optimal temperature for the amplification reaction.A station is described for processing test strips incorporating the reaction vessels. The station includes temperature and vacuum control subsystems to maintain proper temperatures in the reaction vessel and effectuate the transfer of the fluid from one chamber to the other in an automated fashion without human intervention.

Abstract: A housing is mountable on a carousel slide projector. The housing contains a movable light valve slide assembly that is coupled to a video signal source. The light valve slide assembly is movable between a position within the housing and a position outside the housing. When mounted on the slide projector, the light valve slide assembly can be moved into the projection chamber of the slide projector. The video signal source transmits a video signal to the light valve slide assembly, where the video signal is converted to a drive signal to actuate pixels on the light valve. The light valve thus generates a video image that is projected onto a viewing surface. Preferably the light valve is an active matrix liquid crystal display.

Abstract: A display panel is formed using a single crystal thin-film transistors that are transferred to substrates for display fabrication. Pixel arrays form light valves or switches that can be fabricated with color filter elements over the pixel elements. The resulting circuit panel is then incorporated into a color projection display system with a light emitting or liquid crystal material to provide the desired light valve.

Abstract: A flexible backplane assembly is provided wherein removable backplane modules are mounted in a platform in a manner such that the backplane modules may be removed and replaced to accommodate different types of circuit modules. Coacting guides are provided on the platform and the backplane modules to define a travel path for module insertion and removal which prevents contact with adjacent circuit and backplane modules and maneuvers around platform structural members. Connectors at the rear of each backplane module for mating withy circuit module connectors may be electrically connected to I/O boards at the front of the module to permit wiring of the backplane modules from the front of the platform.

Abstract: An open loop, stepper-motor-driven, rigid magnetic disc memory apparatus for use with a data processing system. A rigid magnetic disc with high track density is driven by a stepper motor in an open-loop fashion or without servomechanism control.
