Title: Methods and apparatus for performing ultrasonic assisted surgical procedures
Inventor: VAITEKUNAS JEFFREY J
IPC: A61B17/068
Filed: 1993-11-15
Granted: 2006-10-24
Abstract: Ultrasonic sensing systems are incorporated into surgical instruments to monitor operational fields defined by distal ends of the instruments. The instruments include proximal ends for their activation typically including one or a pair of handles which a surgeon grasps and operates, for example by squeezing the handles together or by pivotally moving a trigger portion of the handle relative to a fixed portion of the handle. Circuitry for performing ultrasonic sensing preferably is enclosed in housings defined within the handles of the proximal ends of the instruments. Wiring, preferably running through the instruments, connects the circuitry to transducers formed in or mounted on the distal ends of the surgical instruments. The transducers direct ultrasonic energy to the operational fields defined by the distal ends of the instruments and receive ultrasonic energy reflected from the operational fields. The direction for transmission and receipt of ultrasonic energy is determined by acoustic lenses, angularly oriented transducer mounts or a combination of the two.    Signals representative of the tissue or contents of the operational fields of surgical instruments drive audible signal generators or preferably tactile transducers to inform the surgeon of the contents. Tactile transducers are mounted for access by the surgeon, preferably on the handles of the surgical instruments:

Abstract: An optical target is acquired by an optical scan- ning system according to an in-band target frequency in an input signal from an opti- cal scanning device. Both the in-band energy level and the out-of band energy level of the input signal from the opt- ical scanning device are de- termined. These two energy levels are compared and a possible detection of the target is determined according to this comparison. A minimum threshold of in-band energy is required in order for the possible detection to be confirmed. The input signal may have various frequencies due to various amounts of magnification of the acquisition target as scanned by the optical scanning device. Thus the input signal may represent the target as various frequencies due to the various amounts o f magnification. The various amounts of magnifica- tion of the acquisition target are due to various scanning distances between  the scanning device and the acquisition target. Magni- fication compensation is therefore performed by providing an amount of frequency shifting of either the center frequency of a fil- ter or the input signal frequency. The amount of frequency shifting is determined according to scanning distance. The frequency shifting is accomplished by performing digital-to-analog conversion on the digital input signal at a flexed frequency. The output og the digital-to-analog converter is applied to an analog-to-digital converter where the analog signal is resampled at a varying re- sampling frequency. When the resampling frequency differs from the sampling frequency the signal is frequency shifted. Alter- nately, the resampled signal may be buffered and clocked out, in which case the frequency of the input signal is effectively shift- ed. In order to vary the amount of frequency shift according to the scanning  distance, the resampling frequency applied to the analog-to-digital converter is varied according to the scanning distance. Th e relationship between the various resampling frequen- cy and the varying scanning distances may be selected to cause the various input frequencies representative of a scanned acquisi- tion target to be shifted to a single predetermined fundamental frequency.</ SDOAB>

Title: Power supply
Inventor: ROSENDAHL GLENN
IPC: H02J3/10
Filed: 1994-02-15
Granted: 1999-01-19
Abstract: A microprocessor controlled system is provided for supplying electrical power to a plurality of electrical outlets for example for use in a parking lot. A central power supply communicates with a series of outlet receptacles each arranged to supply electrical power. Each receptacle has its own microprocessor controlled control unit which is arranged to control the supply of power to the receptacle. A detector unit detects the insertion of a connector plug to the receptacle and actuates a comparator which compares the instantaneous current drawn by the load with a predetermined variable maximum current and allows that current to be drawn only if it is less than the maximum. In the event that the maximum is exceeded, the load is disconnected and is only allowed to be reconnected after the connector plug is removed. A thermostat can be used to control the supply of power depending upon the outside temperature. The microprocessors can select a part only of a cycle for supplying power so that the total power drawn by the central power supply is reduced.

Title: Integrity confirmation of evaporative emission control system against leakage
Inventor: COOK JOHN E
IPC: F02M25/08
Filed: 1993-12-01
Granted: 2004-01-27
Abstract: An on-board diagnostic system for an evaporative emission control system (10) of as internal combustion engine (12) powered vehicle employs a positive displacement reciprocating pump (24) to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump (24) is powered by using engine intake manifold vacuum to force as intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in as air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak is the evaporative emission space. Detection of this rate serves as a measurement of leakage for he purpose of distinguishing integrity of the evaporative emission space from non-integrity.

Abstract: A square saw tooth having four cutting edges of the type which is rotatable about its axis on a saw disc to present a fresh cutting edge when the radially outermost edge wears out has carbide wear plates covering the high wear areas of its attack face and providing its cutting edges.  A wear plate is provided at each corner of the attack face, and each wear plate has a flat rear surface for attachment to the tooth body and a front surface of a complex shape, having plateau surface areas at the corners, where the plates are thicker, and curved surfaces which recede from the plateau areas toward the interior of the attack face, so that the plate recedes in thickness away from the plateau area.  This construction helps provide more uniform wear over the surfaces and edges of the attack face for a more efficient consumption of the wear plates.          In an alternate embodiment, the plateaus are provided at the corners of a tooth having a spherically concave attack face so as to inhibit wear of the corners.

Title: Fast cure and pre-cure resistant cross-linked phenol-formaldehyde adhesives and methods of making same
Inventor: CALVE LOUIS R
IPC: C09J197/00
Filed: 1991-05-13
Granted: 1999-01-19
Abstract: Fast cure and "pre-cure" resistant thermosetting adhesives and methods for their production useful for binding lignocellulosic materials together, are disclosed. A fast curing adhesive is obtained by cross-linking binary phenol-formaldehyde consisting of high average molecular weight phenol-formaldehyde (PF) resin and low average molecular weight PF resin with lignin.  A "pre-cure" resistant adhesive is obtained by cross-linking a PF resin, such as binary phenol-formaldehyde, with a lignin with the addition of ammonia preferably in the form of an ammonium salt.  The lignin may be obtained from different wood pulping waste materials including that recovered from the sulphite, kraft, organic extract or steam hydrolysed wood pulping processes.  The adhesive can be produced as an aqueous solution or dispersion, and used in either a basic or acidic environment.  The quick setting and "pre-cure" resistant adhesives are inexpensive to produce and both display improved adhesion characteristics when compared with existing adhesives prepared from wood waste products.  The adhesives also compare advantageously to a variety of existing commercial phenolic resin presently being used in the manufacture of wood composite products such as waferboards.  These adhesives are capable of being spray dried more easily and produce higher yields, when compared with existing wood waste products which have been cross-linked with commercial PF resin or to a variety of existing commercial phenolic resins.
