Abstract: A wallboard rasp having an expanded metal blade mounted to a molded plastic handle. The handle is configured with a downwardly-opening receiving groove for receipt of an upwardly-curved perimeter portion of the blade. Sections of the blade's perimeter may be crimped or heat staked within the groove. The groove may be formed between a downwardly-projecting outer lip and one or more downwardly-projecting inner ribs. Where the blade is formed with a substantially planar central portion, the ribs may have substantially planar downwardly-facing surfaces against which the blade's central portion may be supported when mounted on the handle. The grip portion of the handle is configured as a contoured, upwardly-extending body having a base with opposite knurled inset surfaces and a convex top flanged surface with spaced-apart grip ribs.

For example, the indicator can indicate a status of the power supply.

Abstract: A distal segment of a catheter shaft is adapted to be positioned against tissue in a biological organ. The distal segment has a tissue-contacting area intended to contact the tissue. One or more pressure sensors positioned within the tissue-contacting area provide pressure data indicative of the pressure exerted on the distal segment. The distal segment carries one or more electrodes and the pressure sensors are located either on an electrode or on the catheter shaft near an electrode. The pressure sensors provide pressure data to a processor that analyzes the data to determine if the tissue-contacting area of the distal segment is contacting the tissue. The pressure sensors may also provide temperature data indicative of the temperature at the sensor. A flow sensor, located opposite the pressure sensor on the shaft, provides data related to the flow rate of fluid through the organ.

Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

Abstract: A catheter balloon formed of a polymeric material such as expanded polytetrafluoroethylene (ePTFE) bonded to a second layer formed of a low tensile set polymer and/or impregnated with a low tensile set polymer. In a presently preferred embodiment, the low tensile set polymer is a silicone-polyurethane copolymer elastomer or a diene polymer elastomer. The low tensile set polymer has high strength, low modulus, high elongation, and low tensile set. The diene or silicone-polyurethane has a low tensile set, which facilitates deflation of the balloon to a low profile deflated configuration. One aspect of the invention provides improved attachment of the diene to the ePTFE. In one embodiment, the second layer is formed of a diene mixed with a bonding promoter such as a vulcanizing agent which is covalently bonded to the diene.

Abstract: A box for conveniently storing and dispensing material has a front wall, a back wall, a first and a second side wall, a first one of the side walls having an opening and an inside surface, a top and a bottom flap, and a slide that is in contact with the inside surface of the first side wall, with the slide having an opening. The front wall, back wall, first and second side walls, and top and bottom flaps are interconnected so as to form a box, the slide being movable between an open position in which the slide opening substantially aligns with the side wall opening and a closed position in which the slide opening is entirely out of alignment with the front wall opening, thereby closing the box. As one option, the slide may have sides which are cut to extend generally parallel to the top flap when the box is in the form of a flat blank prior to box formation.

Abstract: The paracardiac blood pump is destined for protruding through the cardiac wall into the heart with a portion of its housing (10) and for suctioning blood from the heart. The blood is pumped into one of the blood vessels connected with the heart through a line that extends outside the heart. A cannula (30) is arranged in front of the inlet (17) of the pump ring (16). The housing (10) and the cannula (30) have approximately the same outer diameters of 13 mm at most. The housing, together with the cannula (30), can thus be inserted into the heart through a puncture hole that is produced in the cardiac wall without removing material.
