Abstract: An automatically adjustable blanking circuit and method of generating an adjustable blanking interval for use with a dual channel implantable pacemaker includes means for generating a basic blanking interval for a first channel of the pacemaker each time a stimulation pulse is generated on a second channel. The basic blanking interval includes a first absolute refractory portion and a second relative refractory portion. During the absolute refractory portion, the sensing circuits of the first channel are disabled. During the relative refractory portion, the sensing circuits of the first channel are enabled and any activity sensed in the first channel is considered to be crosstalk or noise and the basic blanking interval is retriggered. Retriggering of the basic blanking interval continues for so long as activity is sensed in the first channel during the relative refractory portion of each retriggered basic blanking interval, up to a maximum blanking interval. If no activity is sensed during the relative refractory portion of the basic blanking interval, the blanking interval ends, and the sensing circuits of the first channel thereafter monitor the first channel for spontaneous cardiac activity.

Abstract: It is known to use evaporation caps or covers to seal the tops of test elements when they are in an incubator of a chemical analyzer to prevent evaporation of sample fluids. However, as sample fluid can protrude from the test element because it is not fully absorbed (depending on the nature of the test element), this excess or protruding fluid can be wiped away as the element is moved into and out of the incubator, thereby producing erroneous results when the element is read. Described herein is an arrangement for an incubator (30) which raises and lowers evaporation caps (42) covering test elements (E) at a loading (A) or unloading (D) station. This is achieved by having a fixed camming surface (64, 64′) which acts on a cam follower (56) carried by each cap (42) to raise and lower the cap (42) as the associated test element (E) is moved past the camming surface (64, 64′).

Abstract: A linear peristaltic pump (10) includes a mechanism for maintaining linear flow of fluid through an IV tube. The mechanism comprises a casing (22) carrying a rotatable camshaft (38) having a plurality of cams spaced therealong in helical arrangement and a plurality of fingers (30) coupled to the camshaft. A housing (24) for establishing linear reciprocal movement of the fingers in response to rotation of the shaft establishes a moving zone of occlusion along a tube (16) held against the fingers. Aligning means are included for establishing an axis or rotation of the camshaft which is slightly tilted with respect to the tube. This is accomplished by raising or lowering the upstream or the downstream end of the camshaft to prevent unwanted pressure from building up in the tube to reduce pulsatile flow and maintain linear flow. The aligning mechanism comprises a generally cylindrical bushing (60) having an eccentric hole therethrough for carrying the hinged connection between the casing and the housing. The bushing has a slot (65) therethrough for adjustably rotating the bushing for adjusting the amount of tilt. The adjustment can take place during operation of the pump, having a pressure sensor (50) against the tube, to achieve the optimal positioning of the camshaft depending on the tolerances of the pump mechanism (18) to establish linear flow of fluid through the tube.

Abstract: A laser catheter includes an elongated tubular catheter body, one or more optical fibers extending through the catheter body and a catheter window mounted at the distal end of the catheter body. The optical fibers direct laser energy through the catheter window for removal of biological material. A diffraction grating is formed on the proximal surface of the catheter window in alignment with laser energy from the optical fibers. The laser energy is modified by the diffraction grating to provide a desired spatial distribution pattern. Preferably, the diffraction grating provides a diverging beam suitable for forming a hole in an obstruction, the hole having a diameter that is approximately the same as the diameter of the catheter. The diffraction grating enables formation at the distal end of the catheter of a beam pattern having an elliptical or other noncircular cross section. In another embodiment, an optical fiber with a noncircular cross section is used to shape the laser radiation emitted from the laser catheter.

Abstract: An in use table manager (30) in a computer system uses an in use table (34) to track the use of files, or objects (12, 14). The in use table is used to determine which objects may need recovery in the event of a system failure. Object addresses are hashed by the in use manag­er to identify a preferred slot (34) in the table. The slots contain information identifying the object, and indicating the extent of use of the object. The in use manager assigns alternate slots, and dynamically changes the size of the in use table to reduce contention for slots. Several atomic operations on the table ensure integrity of the table, while permitting concurrent use. Portions of the table are bundled into single I/O opera­tions to enhance system performance by minimizing I/O

Abstract: A flying spot scanner (48, 68) is disclosed, which is particularly applicable to use with a raster output scanner (ROS). The primary scan provided by an ROS is a continuous scan of the optical beam (26) along the scan line [40]. The present invention provides a discontinuous pixel-by-pixel scan in the opposite direction to the continuous primary scan. Thus each pixel is positioned statically at its correct location on the photoreceptor (54) during the pixel's duration. At the end of each pixel's duration, the beam snaps rapidly to the position of the next pixel. Use of this invention forms a non-blurred image of each pixel on the photoreceptor (54). The invention uses an optical deflector (50, 70), to drive the beam opposite to the direction of the primary beam scan during each pixel's duration. The optical deflector (50, 70) may be an angle deflector (50) when used in a collimated optical beam (60), or it may be a translation deflector (70) when used in a non-collimated optical beam (72). This invention provides a flying spot scanner (48, 68) in which all the gray scale detail and resolution available in a pixel is preserved, with no smearing or blurring of pixels, independent of the content of adjacent pixels.
