Abstract: Continuous or periodic measurement of blood gas parameters and blood pressure by separating plasma from blood and then using that plasma to measure the blood parameters. Plasma is separated from blood in vivo with a filter implanted within a blood vessel, and the separated plasma is removed to extracorporeal apparatus for analyzing blood gas parameters or measuring blood pressure. The use of plasma is equivalent to the use of whole blood for measuring blood gas parameters as the gas parameters reside in the plasma, not in the separated blood cells which remain in the blood vessel. This arrangement permits the continuous measurement of blood gases without removal of blood from the body.

Abstract: An immunoassay method for the detection or quantitation of an analyte suspected of being in a solution comprising: (a) combining said specimen, a first binding component, insoluble particles, and second binding component labelled with a signal generating material in a solid phase retention and separation apparatus having a sufficient pore size such that said particles are trapped within said filter yet permitting rapid passage of fluid therethrough in such a manner that an immunological reaction occurs if analyte is present in said specimen, resulting in the formation of an immunocomplex of insolubilized first binding component:analyte:second labelled binding component on or within said filter means; (b) separating bound from unbound material; and (c) determining the presence and/or amount of signal produced which is correlative with the amount of analyte present in the solution.

Abstract: A pedestal assembly for rotatably carrying a load containing radio-sensitive equipment is disclosed, with the assembly having a turntable and base. The profiles of the turntable and base adjacent to one another are both stepped and define a tortuous path between them. The assembly further is designed to distribute any attached load directly to a driven bull gear, rather than to the turntable.

Abstract: An elastomeric material and gloves or condoms made therewith are substantially impermeable to water vapor and liquid water, have a relatively high tensile strength, and have a relatively low resilience. The gloves conform to the shape of a hand when stretched to fit about the hand and then relax so that the pressure exerted on the hand is substantially reduced. The gloves are particularly useful in medical applications and most particularly useful as surgical gloves. Likewise, the condoms conform to the shape of a penis when stretched to fit about the penis and then relax so that the pressure exerted on the penis is substantially reduced. The condoms are useful for preventing the spread of sexually-transmitted diseases.

The disclosed invention further provides a cabinet which effectively utilizes such a device. The disclosed invention also includes an improved cabinet construction which minimizes the paths by which moisture and debris may enter the cabinet interior, while providing a cabinet which is transportable without violating the integrity of the cabinet structure.

Abstract: An improved fire barrier system is disclosed for interposition within an expansion joint between adjacent wall or floor members. In the disclosed embodiment, the invention is characterized in that the fire barrier system is symmetrical in both pairs of opposing quadrants defined by a first axis parallel to and midway between said mutually facing walls and transverse to said direction of elongation and a second axis transverse to said first axis and to said direction of elongation. This symmetry affords equal resistance to fire from either side of the barrier, eliminates the possibility of the joint being installed backwards, and permits the barrier system to be fire-rated for resistance to fire from either side of the barrier on the basis of a single test.

Abstract: A ladder-like stilt, designed to be used in pairs, particularly for ceiling work such as sheetrocking as shown. Two pairs of side rails are joined at a conventional head step area. The area of the otherwise conventional head step is extended by the employment of an elongated head step platform to which a boot is attached for accepting the user's foot. The downwardly projection of the head step platform falls within the footing defined by the distal ends of the side rails, thus providing a stable platform for standing, when the stilts are used in pairs. The boot allows the user to walk on the stilts and perform elevated work, while being able to quickly dismount and climb down the steps.

The invention comprises a plurality of blade members spaced apart by a spacer between each adjacent blade member. Dams may be provided on the spacer. In forming the preferred disc, the plurality of blades and spacers are secured one to the other to form a blade segment. A plurality of blade segments are affixed one to the other to, in turn, form the disc. The invention is characterized by an absence of any mounting plate or base member. The method of the invention is characterized by a continuous weld along either of the inner circumference or the outer circumference of the disc.

Abstract: A data flow controller (150) for monitoring and automatically controlling the flow of serial data from a remote transmitter to a host device. A serial communications card (11) provides an interface between a remote transmitter connected to a serial port connector (20) and a host device (10). The card (11) contains a UART (14) which has a buffer. A counter (151) counts the number of bytes received by the UART (14) since the last time that the host (10) read all the data in the buffer. If the number exceeds a predetermined portion of the buffer capacity the counter output (Q11) will go high, thereby disabling the counter and sending a control signal (DTR, RTS) to the remote transmitter to stop sending data. Once the host (10) has read all the data in the buffer the UART (14) provides a signal (-RXREADY) which resets the counter (151), thereby causing the output (Q11) to go low, thereby allowing the remote transmitter to resume sending data.

Abstract: A bus access controller. An interface circuit (22) controls the access of a host computer (10) and a microprocessor (23) to one or more UARTs (14, 15). The microprocessor (23), which has no provision for waiting for a data transfer, is required to provide a signal of its intent to perform a data transfer prior to beginning the actual data transfer. The signal is identical to the actual data transfer operation. If the host (10) attempts a data transfer operation while the microprocessor (23) is conducting a data transfer operation, or if the host data transfer cannot be completed prior to the time that the microprocessor data transfer will commence, then the interface circuit (22) signals the host (10) that the data transfer will take additional time by deasserting the I/O READY line (12a). Once the microprocessor data transfer is completed then the I/O READY signal is reasserted and the host data transfer is completed.

Abstract: A phase responsive video parameter control system operative for correcting hue, saturation, and luminance of a phase encoded component of a composite video signal. A digital phase detector detects the instantaneous hue of the video image, and provides a signal which selects which one of a plurality of color intervals or bands the detected instantaneous hue falls in. Prestored digital correction values associated with the selected color interval are retrieved from memory and converted into analog correction signals which modify the phase, amplitude, and DC level of the composite video signal. New digital correction values, which reflect operator control panel adjustments, may be loaded into memory during the vertical retrace interval, thereby allowing frame-by-frame color correction.
