  • Patent number: 5403093
    Abstract: A technique for detecting when a full charge for a cell pack is reached based upon sensing an actual temperature of the cell pack. The initial actual temperature is the first value stored as a reference temperature. During subsequent sampling events, the actual temperature is stored as the reference temperature when the actual temperature exceeds said reference temperature. A first value for each sample event is stored in a rollover memory when said actual temperature exceeds the reference temperature, and a second value is stored in the rollover memory when the actual temperature does not exceed the reference temperature. The occurrences of the first values is summed for a series of consecutive sampling events to derive a total. The total is compared to a predetermined limit, and if the total is greater, then charging of the cell pack will be discontinued.

  • Patent number: 5388573
    Abstract: A carrier impregnated at spaced locations along its circumference with a dose of powdered medicament. The carrier is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator. Air is forced through the holes in the pressure plates and the encapsulated dose on the carrier to entrain a dose of the powdered medicament, which is then inhaled through a mouthpiece, by the patient-user. The powdered medicament is embedded in and across interstices in the carrier formed by intersecting and sometimes offset depressions on each surface of the carrier, providing corners and surfaces to cause the medicament entrained in the air stream to break up as it is pressed up against and passed through the carrier infrastructure to aerosol or atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.

  • Patent number: 5388572
    Abstract: A dry powder inhalator for delivering a precise dose of a medicament contains a mesh disc impregnated with a series of spaced, medicament doses about the disc periphery. The inhalator is armed by manually retracting a finger pull extending downwardly from the bottom of the inhalator housing or rotating the bottom of the housing. The user inserts a mouthpiece on the housing into the mouth and inhales. This causes a chamber in the housing under a diaphragm to evacuate, thereby pulling the diaphragm down onto a knock out lever. The pivoting of the lever enables release of a piston into a cylinder which first compresses, and then dispenses a reduced volume of air at high pressure in a burst up through the medicament disc. When the burst of air hits the impregnated disc, the dose is forced out of the mesh's interstices, producing a cloud of the drug in its powdered form, which is inhaled by the user.

  • Patent number: 5384616
    Abstract: A photographic lighting system for use with a camera provides fill light from the direction of the camera to alleviate shadows in a photographic image obtained by the camera. The photographic lighting system includes an incident light sensor for sensing the incident light intensity on a subject to be photographed, an electric light for directing fill light toward the subject, and a control circuit for controlling the intensity of the fill light provided by the electric light in response to the sensed incident light intensity. The fill light is increased in intensity as the incident light intensity increases. The control circuit can also receive a distance input representative of the distance between the electric light and the subject and controls the fill light in response to the distance input such that the fill light intensity at the subject is substantially independent of the distance.

  • Patent number: 5377219
    Abstract: A device includes a transmitter for transmitting a first optical signal towards a target, which incorporates an optical parametric oscillator. A receiver is capable of receiving a second optical signal from said target. The second optical signal is the reflected signal from the first signal. The receiver means comprises an optical parametric amplifier. A wavelength matching device matches the wavelengths produced by the optical parametric oscillator with that received from the optical parametric amplifier. The optical parametric amplifier is typically joined with a laser to form an optical parametric amplifier laser, while the optical parametric oscillator is joined with a laser to form an optical parametric oscillator laser.

  • Patent number: 5361913
    Abstract: The apparatus consists of a machine for refunding glass bottle deposits, crushing the bottle and sorting the crushed glass as to color, either clear, brown or green. The bottle has a label provided with an optically read bar code which identifies the bottle's 1) color, 2) whether it must be returned to the manufacturer in one piece, and 3) whether a refund is, in fact, due for the particular bottle. The bottle is inserted in the apparatus and the bar code on the bottle passes beneath an optical scanner. If the bottle is refundable and of a particular color (i.e., clear, green, brown), a microprocessor electrically connected to the scanner activates a door and a deflector causing the bottle to fall into a glass crusher including a bin provided with a rotating plate which smashes the bottle. A chute beneath the glass crusher is positioned by the microprocessor so that the crushed glass is conveyed to one of three collection bins depending on the sensed color.
