Abstract: A remotely actuated surface cleaning device employs an inner component having a resiliently flexible body with a plurality of embedded magnets and a cleaning element to engage a surface to be cleaned. An outer housing containing an electric motor moves a support disc containing an operably like plurality of magnets to those embedded in the body. The inner and outer components are placed oppositely adjacent on the surface to be cleaned thereby supporting the inner component with respect to the outer component by magnetic attraction. Operation of the motor moving the second support disc causes the sympathetic motion of the first support disc and body thereby rapidly moving the cleaning element across the surface to be cleaned.

Abstract: A heart rate monitor adapted to be worn on eyewear such as a pair of eyeglasses, a mask or goggles. The heart rate monitor includes a sensor in contact with the bridge of the user's nose. The sensor is responsive to pressure variations or pulses produced during a heart beat cycle. The sensor provides an analog signal having a frequency equal to the user's pulse rate. The analog signal output from the sensor provides an input signal for a microprocessor which includes a frequency counter and signal averager. A microprocessor output signal having a magnitude which is proportional to the heart rate in beats per minute provides the input signal for an optical readout device such as a digital display which is preferably mounted on the frame or stem of the user's eyewear. The image on the optical display is conducted to an eyepiece lens which is mounted most preferably on one of the lenses of the eyewear by means of an image conduit such as a fiber optic or fiber optic bundle.

Abstract: A surgical cutting device having a powered handpiece adapted to receive a cutting blade. The cutting blade is locked to the drive shaft by a locking ball holding member which is locked in place by a cylindrical cam ring which urges the balls of the locking device into corresponding notches in the blade. A second locking ball holding member is provided on the housing of the handpiece to lock the cylindrical cam ring itself. A blade guard extends from the cylindrical cam ring to produce a surgical cutting device having an improved safety feature which prevents its operation without the guard in proper position.

Abstract: A display apparatus secured to a temple or bridge contacting portion of an eyewear, the apparatus including means for monitoring the wearer's heart rate, lap position, laps completed, time elapsed, etc. An image of the collected data is transmitted into the wearer's field of view by means of a fiber optic element and projected at a focal point within the focusing range of the wearer's eyes.

Abstract: An implant being securely fixed in a bone by a layer of plastic cement is removed by supplying a pressurized fluid to the interface between the cement and the implant.

Abstract: The lens device includes a lens joined to a lens holder member, the lens holder member having a diverging wall portion that permits suction mounting of the lens device onto a substantially smooth surface. The lens is held by the lens holder member to permit a field of view through the lens and through any surface upon which the lens device is mounted. The lens device is thus conveniently mountable upon the lens of an eyeglass or goggle, the screen of a monitor or radar scope or any other device where it would be beneficial to magnify a selected field of view. Suction mounting of the lens device permits easy removal and relocation of such device on a selected surface or relocation onto an entirely different surface. The lens device is also combinable with an appliance such as a digital stopwatch to provide a module that is suction mountable onto a pair of goggles. A swimmer is thus enabled to keep track of elapsed time while swimming.

Abstract: The oral implant is in the shape of a cylinder with a flat proximal end and a rounded distal end. Projecting members are formed on the cylindrical surface that taper from the proximal end of the cylindrical body toward the distal end thereof. The projecting members are radially spaced, and in one embodiment have flutes formed on the tapered surface. A lateral through-hole is provided at the distal end of the cylindrical body. The proximal end includes a hexagonal-shaped recess for reception of a twisting tool. After the twisting tool is removed the hexagonal recess receives a dental prosthesis. Another embodiment of the oral implant includes radially spaced ridges that are longitudinally aligned with projecting members on quadrants of the cylindrical surface.

Abstract: The adjustable support for a prosthetic tooth includes an abutment member having an opening for reception of a bolt member that engages with a nut member. The abutment member is sandwiched between a head portion of the bolt member and an enlarged collar portion of the nut member. The engaging surfaces between the head portion and the abutment member and between the abutment member and the enlarged collar portion of the nut member are of complementary shape with respect to each other to permit pivotal adjustment of the abutment member with respect to the bolt and nut members. The abutment member is thus pivoted to a desired position and the bolt and nut members are tightened to lock the abutment member in the desired position. A prosthetic tooth having an opening of complementary shape with respect to the abutment member engages the abutment member to assume the angular orientation of the abutment member.

Abstract: The preferred embodiment provides a stopwatch mounted in a lens, goggle, mask or shield for use by a swimmer or other goggle wearer to observe elapsed time during, or countdown time prior to, an activity.

Abstract: The valve includes a housing with inlet and outlet members joined by a resilient flexible valve closure. An annular chamber that does not communicate with the inlet or outlet surrounds the valve closure. When a flow of fluid is desired through the valve closure, a pressurized fluid is introduced into the annular chamber to deform the valve closure enabling the closure to open. Reduction or elimination of the pressure for deforming the valve closure permits the valve closure to assume its normal closed position, thereby permitting a shut off of fluid flow. Variable flow rates can be accomplished by obtaining predetermined deformations of the valve closure corresponding to predetermined levels of the pressurizing fluid which cause such deformation.

The container is adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants. The container may include an integral battery charger adapted to withstand exposure to the environment of a sterilization process. Alternatively, the container may include a connector for releasably electrically connecting the battery housed within the container to a distinct, external battery charger.

Abstract: The present invention provides apparatus for changing the direction of rotation of a rotating shaft without changing the direction of rotation of the motor driving the shaft. The present invention includes a drive gear which causes two driven bevel gears to rotate in opposite directions. A control shaft having cam surfaces selectively forces one of two sets of balls into engagement with one of the driven gears to couple that gear with the driven shaft to rotate the shaft in one direction. Rotation of the driven shaft is reversed by changing the position of the control shaft which uncouples one set of balls from the driven shaft and couples the remaining set of balls to the driven shaft.
