Abstract: A liquid/gas pump includes a stainless steel strip of uniform width that is encased within a flexible and liquid/gas impermeable plastic tube whose inner diameter is only somewhat less than the width of the metal strip. The tube is thus deformed to a generally elliptical shape, and the longitudinal edges of the metal strip are sealed by physical contact with the inner diameter of the plastic tube. Two elongated passageways are thus formed, one passageway being above the metal strip, and the other passageway being below the metal strip. A linear series of bistable position and somewhat overlapping shallow domes are formed into the metal strip. As one end of the plastic tube and metal strip assembly is reciprocated relative to the other end, the metal domes pop from one side of the metal strip to the other side. As a result, the volume of a first passageway increases as the volume of the other passageway decreases.

Abstract: A multifunction collar, harness, belt or leash is provided having a accordion-fold portion that collapses to a thin shape when the collar, harness, belt or leash is in use and pulled to a taut or tight condition, and that expands when the collar, harness, belt or leash is released to a slack condition, the expanded accordion-fold portion then providing an open-top bowl or cup.

Abstract: A processor that executes coded instructions using an instruction scheduling unit receiving the coded instructions and issuing an instruction for execution. A replay signaling device generates a signal indicating when the instruction failed to execute properly within a predetermined time. A replay device within the instruction scheduling unit responsive to the signaling device then reissues the instruction for execution.

Abstract: A system, method and computer program product comprising a storage manager independent configuration interface translator which requests an opaque listing of the available storage devices from an associated metadisk driver and determines a subset of the listing meeting a preselected search criteria. The resultant opaque listing is then converted to a non-opaque format listing for presentation to a user of the computer system in a desired format such as through a command line or graphical user interface. A notification mechanism is also provided that presents information about storage devices which have in some way changed while in use.

Abstract: A method and apparatus for converting ASCII path names to parsed path name structures provides downward compatibility so that program modules written for modern operating systems which provide parsed path name structure inputs may be run under older operating systems which provide ASCII path name inputs. The method includes, in its most basic form, the steps of converting the prefix and file name of an ASCII path name to a unicode string, then converting the unicode string to a parsed path structure. In a preferred embodiment of the invention, the method is implemented in compiled object code written in the "C" computer programming language.

Abstract: A system, method and computer program product of especial utility in allowing a user to insert a diagnostic computer program probe into an operating application computer program to either obtain a readout concerning the state of the application program or to introduce new behavior into it such that the results can be monitored. Through the provision of a number of application computer program probe points and corresponding diagnostic computer program probes herein disclosed, the invention may be utilized in conjunction with an operational application program and the corresponding diagnostic program may be developed independently of the application program the behavior of which is to be diagnosed.

Abstract: A chemical detection and analysis system performs chemical measurements using microsensors. The in vivo or in vitro system records chemical concentrations of any substance that can be oxidized or reduced at the sensor surface in response to a voltage waveform applied to a reference electrode. The electrochemical technique has utility relative to molecules that are electroactive. Diffusion and metabolism of these chemicals are tracked in real time. A visual display of the measurements is provided in near real time. The system consists of: a 32 bit, digital computer; application software; an I/O board with analog to digital convertors, digital to analog converters, and digital input/output capability; a potentiostat; one to four microsensors; and a reference electrode. Calibrated microsensors, of carbon, platinum, or gold, are placed in brain tissue or other aqueous environments to detect chemical activity. A reference electrode is placed in the tissue at a location that is spaced from the sensors.

Abstract: An apparatus and a method are provided to monitor a generally transparent blood tube at a location that is downstream from a blood separator in order to detect the presence of red blood cells in a tube that is intended to carry a different blood component, for example platelets. A red light source and a green light source are located in relation to the tube so that red light emission and green light emission are directed toward the tube and toward the flowing blood component(s) that is carried within the tube. The red light source produces a red reflection intensity from red blood cells whose magnitude increases as a function of an increase in the concentration of red blood cells. The green light source produces a green reflection intensity from the red blood cells whose magnitude decreases as a function of an increase in the concentration of the red blood cells.

Abstract: A loose leaf page for selectively storing four compact discs (CDs) on each side of the page, or for storing two CDs and associated printed and graphic information on each side of the page. A flexible, plastic, two-sided, loose leaf page includes four CD storage pockets per side of the page, and includes a hole pattern that facilitates releasably mounting the page in a standard cover-size 1-inch, 1 1/2-inch or 3-inch three-ring binder notebook, certain embodiments also facilitating mounting of the page in a three-ring Chicago-posted binder. In order to prevent interference between two CDs that reside closest to the binder rings when a user manually leaves through binder pages, the page includes a six-hole pattern, a three-hole/three-notch pattern, or the page's binder-edge is configured to ensure that the vertical binder-edge, upon the page being turned, moves past the vertical leading edge of the three rings, and then moves backward under the three rings.

Abstract: A flux enhanced data transducer and method for producing the same in conjunction with shared shields on MR read heads in which substantially between 500-2500 .ANG. of a relatively higher magnetic moment material is added to the upper surface of the shared shield, or bottom write head pole, prior to a magnetic flux containment ion milling operation utilizing the upper pole as a mask. The relatively higher magnetic moment flux enhancement layer may comprise CoNiFe, FeN or similar material which is deposited prior to the formation of the dielectric gap layer. The flux enhancement layer may then be selectively removed substantially surrounding the upper pole by means of a relatively brief ion milling process in which only on the order of 1.0 k.ANG. of the layer need be removed and during which only an insignificant amount of the material removed might be re-deposited on the sides of the upper pole.
