  • Patent number: 4562841
    Abstract: A programmable cardiac pacemaker that is selectively programmable via a radio frequency communications link into one of a plurality of a single and dual chamber pacing modes. Depending upon the mode selected, an associated plurality of pacing parameters may be programmed, each within a predetermined range of possible magnitudes.The pacemaker includes a rate smoothing function for preventing the rate interval from changing by more than a predetermined percentage on a cycle-to-cycle basis; and a graceful degradation function for causing the ventricular pacing rate to decay when the atrial rate exceeds a programmed upper rate limit for a predetermined length of time. A graceful degration onset time and rate of decay are also programmable. Additionally, the pacemaker contains a set of pre-programmed alternative pacing parameters for at least one mode and which can be independently reverted to.The pacemaker control circuitry is organized about a central bus into an I/O controller and a pacing controller.

  • Patent number: 4540877
    Abstract: A temperature controller for monitoring the temperature of a rotating heating system and regulating the temperature relative to a desired temperature. A transmitter within the rotating system coupled to a remote stationary controller via slip rings produces a magnitude varying current control signal within a calibrated range at a magnitude proportional to the sensed temperature. A pair of voltage dividers within the transmitter establish the level and range of current magnitude relative to a constant current source. The remote stationary controller compares the current control signal to a set-point and synchronously supplies power to the heater elements of the rotating system, so long as the sensed temperature is below the desired temperature.

  • Patent number: 4538544
    Abstract: A machine for surfacing floors by laying down a floor covering compositions, as for example asphalt, comprises an anchoring base that may be braced between two floors or bolted to the floor under it. On the base there is a pivoting boom made up of articulated links with upright pivot axes. At its outer end, there is a floor working head fixed on the boom. The base is made up of two separate leveling units placed at 90 deg to each other as well as a height adjustment unit. By providing a separate anchoring base, it is possible for the floor surfacing machine to be used both indoors and outdoors. It also allows simple and accurate leveling of the end of the boom and facilitates the working of a very wide range of different flooring compositions over large areas.

  • Patent number: 4537194
    Abstract: This invention relates to the field of medical instruments and particularly to an applicator used to apply a frozen solid such as ice to a wound or injury to treat the wound or injury. The invention is comprised of first and second container means. The first container means has an open top of a predetermined size, a tapered side wall and a bottom having a central opening therethrough. The second container means has a shape conforming at least in part to that of the first container means, an open top and a closed bottom. The two container means are fitted together by placing the bottom of the first means into the top of the second container means. The device can then be filled with liquid and frozen until needed. When in use as an applicator, the second container means is removed and the first container means serves as a handle for applying the frozen solid.

  • Patent number: 4538229
    Abstract: A computerized system for examining single engine performance capabilities and developing alternate routes/routings for two-engine aircraft in compliance with FAR 121.19 (driftdown, one engine inoperative) such that an attendant loss of altitude will not result in the aircraft dropping below a net flight path altitude and clearance distance with respect to the earth's surface along a given route between a flight originating point and a destination. Included as a part of the computation are the radius of action fuel capabilities which takes into consideration the "maximum continuous thrust", the power demands on the remaining engine, air density-temperature change attendant with altitude loss, and real time wind conditions.

  • Patent number: 4532931
    Abstract: A sensing circuit for a cardiac stimulator which can adapt to the use therewith of either bipolar leads or unipolar leads without the need for telemetric programming of a switch internal to the implanted pacemaker. If a unipolar lead is plugged into the terminal receptacle of the pacer at the time of implant, the pacer will sense R-wave activity and other artifacts between a distal tip electrode and the metal body of the pacemaker, but if a bipolar lead is plugged into that same receptacle at the time of implant, the pacer will sense such artifacts between a tip electrode and a ring electrode spaced a predetermined short distance proximally of the tip electrode along the surface of the lead body.

  • Patent number: 4531943
    Abstract: A catheter for insertion in a body orifice or blood vessel comprising an elongated tubular body with a soft, symmetrically deformable member on the distal end thereof for decreasing the likelihood of injury to body tissue upon the insertion and removal thereof. In one embodiment, the tip member comprises a toroidally shaped inflatable and non-distensible expandable "balloon" mounted on the end of the otherwise relatively rigid tip of the catheter. The catheter has a lumen extending the length thereof and communicating with the tip member whereby a fluid may be introduced to control the size, shape and firmness of the tip member. In a second embodiment, the soft deformable tip member comprises an annular plastic or rubber sleeve surrounding the otherwise rigid tip of the catheter and normally extending there beyond by a predetermined distance. The thickness or composition of the sleeve is varied about a circumferential ring so as to provide a preferred location for the collapse of the sleeve.
