Abstract: A sensor package for a microelectromechanical system (MEMS) is provided. The sensor package comprises a slot for receiving a MEMS, a bonding area in, or adjacent to, the slot for bonding the MEMS to the package and at least one package electrode to engage an electrode pad on the MEMS. Each package electrode is in communication with a conductor pad for connecting the MEMS to an electronic device.

Abstract: A method for real-time observation of absolute ventricular volume wherein electrical measurements are made with a tetra polar catheter and compared to electrical measurements in a database, said database being assembled using electric field theory to predict the non-linear relation between blood volume and electrical measurements between a fist limit characterized by an infinitely thick volume of blood and second limit characterized by infinitely thick tissue completely surrounding the catheter. The calculations are performed under the assumption that the blood is surrounded by an infinitely thick region of tissue.

Abstract: The novel dump body enables a dump truck to carry large, packaged loads and large, loose loads. The dump body includes a containment base having a bottom and a plurality of sides. The dump body further includes a dumping mechanism formed in one of the plurality of sides for releasing loose materials when the containment base is tipped. Finally, the dump body includes at least one side door pivotably attached to the containment base and covering a first opening formed in at least a portion of one of the plurality of sides. The side door permits packaged loads to be loaded onto the dump truck, wherein the sides on the dump truck normally prohibit the carrying of this type of load.

Abstract: Disclosed is a method of testing a substance for the ability to affect the formation or oligomerization of a complex comprising members of a specific binding pair, a first member of the binding pair being present on the surface of a lipid enveloped particle comprising a transferrable label, said first member of the binding pair being capable of binding to a second member of the specific binding pair present on the surface of a cell, the lipid envelope of the particle being capable of fusing with the membrane of the cell so as to transfer the label to the cell, said transfer being inhibited by formation or oligomerization of a complex between the first and second members of the binding pair, wherein the method comprises reacting the particle and the cell, in the presence of the substance under test, (under conditions which would allow for binding of the first and second members of the specific binding pair in the absence of the substance under test), and detecting the label transferred, if any; together with a

Abstract: A compensating circuit arrangement for a power transmission system for rapidly inserting capacitance into a transmission line for desired portions of cycles of the operating frequency of the system, has first anti-parallel connected thyristors in series with a capacitance and second anti-parallel connected thyristors in parallel with the series connected first thyristors and the capacitance. A control responsive to a variable in the system, and related to system reactance, switches desired thyristors on at desired times during a cycle of operating frequency to introduce controlled amounts of capacitance into the power transmission system.

Abstract: Disclosed is a method for preparing a stabilized enzyme dispersion wherein the dispersion is prepared by precipitating a water-soluble polymer from a single phase, aqueous solution to form an aqueous dispersion, and before, simultaneously with or after precipitating the polymer, contacting the dissolved or dispersed polymer with an aqueous solution or fine aqueous dispersion of an enzyme without any covalent bonding between the polymer and the enzyme. Also disclosed is a clear solution for use in the method.

Abstract: A system having a bus protected against overvoltage by a plurality of series connected zinc oxide varistors in a column, uses temperature sensors to protect the varistors from damage. First temperature sensors detect that a safety tripping temperature has been reached and lower the bus voltage. Second temperature sensors detect a thermal runaway temperature has been reached and disconnect the bus. Normal operation is restored when the detected temperature falls below the safety tripping temperature. To protect against very rapidly increasing overvoltages, the current flow is monitored and when it exceeds a threshold a signal representing current is integrated. When the integrated value reaches a first preset level the voltage on the bus is reduced and when it reaches a second preset level the bus is disconnected to permit the varistors to cool.

Abstract: A protective circuit for a plurality of series connected thyristors where each thyristor has in parallel with it a resistance, capacitance type snubber circuit and a metal oxide varistor. The arrangement of the series connected thyristors, snubber circuits and their metal oxide varistors has in parallel with it a main metal oxide varistor. The main varistor is responsive to external transient surges so as to conduct large currents. The outer varistors are selected to have values so as to conduct a much smaller or minimal current relative to the current conducted by the main varistor. In a preferred arrangement, a tuning inductor is in series with the thyristors, snubber circuits and parallel arranged varistors. Also, the main varistor is arranged in parallel with the series connection of thyristor, snubber, varistor combination and inductor, and in series with a bank of capacitors.
