Abstract: A method of measuring blood clotting ability of a patient. A known volume of blood is dispensed on a reference disc of blotter paper, such that at least one reference blotch is formed on the reference disc. The surface area of the reference blotch formed on the reference disc, such that a relationship between the volume of blood and the surface area of the reference blotch can be obtained. An incision is made at the patient. A piece of blotter paper to the incision is applied to the incision to collect blood flowing therefrom, such that at least one blotch is formed on the piece of blotter paper. The surface area of the blotch formed on the piece of blotter paper is measured. The volume of the blood absorbed blood by the blotter paper is calculated according to the relationship between the blood volume and the surface area of the blotch.

Abstract: A pneumatically actuated valve assembly for use as intake and/or exhaust valves on two- or four-stroke internal combustion engines. The assembly includes a valve (100), valve housing (200), and compressed gas distribution and timing mechanisms (FIGS. 5-8). The valve (100) is comprised of a short light weight hollow cylindrical body with a capped lower end and an opened upper end. The valve is further defined by a plurality of ports (104) adjacent to the lower end and a collar (198) encircling the body adjacent the upper end. The valve housing (200) is hollow and tubular having a larger diameter upper section and a smaller diameter lower section in which the valve (100) slides up to close and down to open. The housing (200) further includes hollow channels which direct compressed gas, managed by the distribution and timing mechanism, alternately towards the areas above and below the valve collar at regular intervals to open and close the valve, respectively.

Abstract: A method for accelerating subcutaneous absorption of a fluid or drug into the systemic circulation of a specific targeted tissue. A first drug operative to produce local capillary vasodilatation and/or increase the rate of bulk flow of solution through the interstitial space is mixed with a fluid. The fluid may contain a crystalloid solution or a dilute solution of a pharmacologic drug required for a routine or emergency therapeutic treatment for a patient. The first drug is substantially non-toxic to the patient. The fluid mixed with the first drug is then delivered subcutaneously or into deeper tissues of the patient, by use of a hyperdermic needle or infiltration cannula. As the capillaries are dilated, the fluid is efficiently absorbed and circulated systemically.

Abstract: An exemplary multi-channel speech processor comprises a controller capable of interfacing with a plurality of channels, and at least one signal processing unit (SPU) coupled to the controller, where the multi-channel speech processor has a maximum execution time for processing all frames, one channel at a time, by processing a single frame from each of the plurality of channels. The signal processing unit encodes each of the single frames from each of the plurality of channels, one channel at a time, to generate encoded frames until the maximum execution time elapses or is about to elapse. The controller also transmits a predetermined frame for each of the plurality of channels not processed during the encoding step, due to the maximum execution time elapsing or being about to elapse, such that the predetermined frame causes a decoder which receives the predetermined frame to generate a frame erase frame.

Abstract: Newly installed electrical units emit, for a brief install interval, an “installed” output either audibly or visually, or both in response to an install mode input signal. After the install interval, the “installed” output ceases. As more units are installed, the earliest installed units remain silent in the presence of the install mode input signal.

The arrangement includes at least one support structure having a support base and a movable platform connected to the support base by spaced-apart 2-bar linkages with center pintels and a series of length adjusting members between the pintels and the support base. A length adjusting member is located between the movable platform and the support base, wherein the lengths of the length adjusting members set the orientation of the movable platform. In accordance with another embodiment of the present application, welding support structures are arranged in a linear array, wherein each of the welding support structures include a movable platform. At least some of the movable platforms of the plurality of support structures are moved to predetermined orientations.
