Abstract: A method and apparatus for operating a pool cleaner body in a manner to maximize the time spent on cleaning relative to the time spent on repositioning. More particularly, the invention is directed to a control subsystem for operating a cleaner body to enable it to primarily travel in a forward direction (i.e., forward state) along a travel path but operable also in a backup/redirect state to translate and or rotate the body to enable it to escape from obstructions while also minimizing the formation of conduit tangles. The control subsystem is configured to perform reposition operations without increasing incidents of conduit tangling by: 1—avoiding an excessive rotation of the body, e.g., approximately 180° or more, when attempting to free the body from an obstruction; and/or 2—avoiding the initiation of a timed reposition operation while the body is transitioning between a travel path at the wall surface and a travel path at the water surface.

Abstract: A system for automatically manipulating prerecorded audio data to produce an audio track synchronized to a target video track. The system allows a user to select a music source from multiple music sources stored in a music library. Each music source includes multiple audio portions having block data and beat data associated therewith. The block data includes data blocks respectively, specifying the duration of the associated audio portions. Each data block preferably also includes interblock compatibility data and/or suitability data. The beat data, generally referred to as a “beatmap”, comprises timing information specifying the rhythmic pulse, or “beat” for the associated music source portion. The system is operable to produce an audio track synchronized to a video timing specification (VTS) specifying successive timing segments delimited by successive video events. After the user selects a music source, the system generates a music segment for each defined timing segment.

Abstract: A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve having a tapered forward portion to facilitate its insertion through an undersized incision. The sleeve provides an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve.

In accordance with the invention, the SCU comprises a programmable unit capable of (1) transmitting commands to at least some of a plurality of implanted devices and (2) receiving data signal from at least some of those implanted devices. In accordance with a preferred embodiment, the system operates in closed loop fashion whereby the commands transmitted by the SCU are dependent, in part, on the content of the data signals received by the SCU.

Abstract: Improvements are described in the injection of ammonia (NH.sub.3) into the exhaust gases of an engine to reduce nitrogen oxides. Instead of merely injecting ammonia into the exhaust gas conduit through a hole in its side, an ammonia injector (90) is provided that projects considerably into the exhaust conduit (16), with the injector having a plurality of holes (94). The ammonia is activated to decompose it into its reactive components, including NH.sub.2 and NH prior to injecting it into the exhaust conduit. Such activation prior to injection can be accomplished by heating the ammonia in the presence of a catalyst such as a metal of the platinum group, iron, nickel, or zinc. In an engine that has a fuel injection system wherein electrical pulses are delivered to fuel injectors to control the fuel flow rate, the durations of these electrical signals are used to control the opening of a valve (72) that controls the flow rate of ammonia into the exhaust gas conduit.

Abstract: An earplug of the slow recovery type is described, which has open cells for expelling gas to the outside during compression, but which resists the entry of water through the outside and the soiling of the outside by dirt. The earplug includes a body formed of pressure-molded slow recovery resilient foam material forming multiple gas-filled shells. The plug body has a surface region forming a skin wherein the average cell cross-sectional area is less than half that of cells at the center of the body, and is less than one-tenth millimeter, the surface region being primarily continuous.

Abstract: A system is provided for changing hydraulic oil in vehicles such as airplanes, which enables rapid replacement of dirty oil and rapid cleaning of oil to meet military/commercial aircraft specifications for reuse. The apparatus includes a frame (40), dirty and clean oil tanks (14, 16) mounted on the frame, a filter tank (30) with filters (32) mounted on the frame, and pump and valve means (20) for controlling the flow of oil. Initially, the apparatus is rolled up to an airplane, dirty oil in the hydraulic reservoir of the plane is pumped into the dirty oil tank, and clean oil from the clean oil tank is pumped into the airplane reservoir. Thereafter, while the apparatus is moved or is stationary, dirty oil from the dirty oil tank is pumped through filters of the filter tank and into the clean oil tank for an initial cleaning, and thereafter the oil is continually circulated from the clean oil tank through the filtered tank and back to the clean oil tank to polish the oil.

Abstract: A rotary fluid valve has a pivotable disk (36) with through slots (38, 39), the disk blocking outer ends of ports (31, 32) in a neutral disk position. When the disk pivots in first or second directions from the neutral position, one of its slots moves into line with one of the ports. This allows pressured air to flow from the now-uncovered port and through the disk slot, and through an upper chamber (46) lying against the upper face of the disk, to allow air to flow between an external fluid coupling (17 or 18) that is coupled to the port, to another external coupling (19, 20) that is coupled to the upper chamber, as to inflate or deflate a vehicle air bag.

Abstract: An apparatus useful for detecting the speed and/or position of an object moving along a defined path and more particularly to such an apparatus configured to minimize the spacing between a sensing face of the apparatus and a target surface on the object. Embodiments of the invention are particularly suited for sensing the speed of a rotating member, e.g., a gear, by utilizing a sensor, such as a Hall-effect sensor, to detect the movement of each gear tooth past the sensor. An apparatus in accordance with the invention is configured to mount the sensor for adjustable positioning along a sensor path between an initial position and a final operational position. Movement of the sensor along the sensor path is restricted, e.g., by frictional engagement, but can be overcome by contact with the target surface so as to move the sensor to its final position with the spacing, i.e., airgap between the sensing face and the target surface, minimized.

The teachings of the invention are further extended to dual band feed structures (124, 220 and 320). The structures are particularly suited to enhance high signal to noise ratios because of short path lengths to external receiver circuits and to enable realization in simple economical one piece castings.

Abstract: An apparatus for calibrating color settings of a computer monitor to cause a proofed image, i.e., a prepress image, to essentially match a printed image on a particular medium, allowing the aesthetic quality of the image to be adjusted prior to printing, thus saving time and money. Embodiments of the present invention comprise a first set of separate red, green and blue monitor sensors (RGB) coupled to the computer monitor to sense a reference image and a second set of RGB ambient sensors facing upwards to sense ambient illumination. A set of RGB digital displays indicate numerical values representative of the computer monitor illumination as read by the monitor sensors and adjusted by the ambient sensors. A predefined table is used to reference the indicated values for particular medium and these values are used to adjust gamma values on the red green and blue color guns of the computer monitor.
