  • Publication number: 20190335551
    Abstract: In a photobiomodulation therapy (PBT) process, defined patterns (e.g., sequences of square-wave pulses, sine waves, or combinations thereof) of electromagnetic radiation (EMR) having one or more wavelengths, or spectral bands of wavelengths, are introduced into a living organism (e.g. a human being or animal) using a distributed system comprising two or more distributed components or “nodes” communicating using a bus or transceiver to send instructions or files between or among the constituent components. The distributed PBT system prevents intentional usurpation of system control (hacking), thwarts unauthorized monitoring of data (surveillance), and reduces the likelihood and severity of accidental system malfunction arising from corrupted command and control packets or ambient EMI.

  • Patent number: 6817472
    Abstract: A packaging component and packaging system are disclosed. In an embodiment specifically adapted as a system for packaging vehicular radiators, the invention provides a generally planar tray member component as a blank having two opposed sides, with a portion of each opposed side being foldable out of the plane of the tray member to yield arms to the tray. Strapping is supplied which is engageable with the arms when the arms are folded upon the radiator placed upon the tray member. Opposed ends for the tray member have a portion which is likewise foldable out of the plane of the tray member, yielding legs to the tray when so folded. The packaging system can include at least one stand-off element mountable on one of the radiator and the tray member operating as a spacer and positioner relative to a container within which the tray member is received with the stand-off element mounted in place.

  • Patent number: 5260730
    Abstract: A relatively small liquid-crystal display (LCD) device located well above the fresnel stage of an overhead projector produces large, sharp images with full color and motion. A focus-correcting lens moves with the overhead projector's optical head to maintain proper projection-focus and magnification. Spectrally-selective filters are interposed between the LCD device and fresnel stage to avoid LCD deterioration. A fan-actuated shutter or electrically-actuated shutter optionally provide still further protection. Optical collimation methods are employed to attain a large depth-of-field and image brightness.

  • Patent number: 5063297
    Abstract: An apparatus for detecting the fluorescence of a luminescent material. Photo-semiconductors receiving the visible fluorescence from a target luminescent material and directly from a discharge lamp are electrically coupled to oppose each other resulting in a single-channel detector inherently balanced and insensitive to variations in the excitation stimulus. The photo-semiconductor output is sent through a second harmonic amplifier making available a phase detection of the fluorescence instead of an amplitude detection. The phase of the signal is compared with a known phase from the excitation power source. By adding signals that either reinforce or oppose, the phase information is converted back to amplitude information at a voltage level that can be easily detected. The compared output then triggers an indicator producing an indication of the amount of fluorescence of the target luminescent material.

  • Patent number: 5030832
    Abstract: An apparatus for detecting the fluorescence of a luminescent material. Photo-diodes receiving the visible fluorescence from a target luminescent material and a luminescent reference are coupled "back-to-back" resulting in a single-channel detector inherently balanced and insensitive to variations in the excitation stimulus. The photo-diode output is sent through a second harmonic amplifier making available a phase detection of the fluorescence instead of an amplitude detection. The phase of the signal is compared with a known phase from the excitation power source. By adding signals that either reinforce or oppose, the phase information is converted back to amplitude information at a voltage level that can be easily detected. The detected amplitude is compared against the amplitude of the excitation stimulus to account for amplitude variations in such stimulus. The compared output then triggers an indicator producing an indication of the amount of fluorescence of the target luminescent material.

  • Patent number: 4930886
    Abstract: An opaque adapter for an overhead projector uses a hood with clamshell doors to provide generous access to the projector stage during transparency projection and efficient light shielding during opaque projection. The clamshell doors are oriented upon hinges slanted to the vertical so as to rise away from the stage when opened. Spring devices offset the gravitational forces on the doors, allowing rapid motor actuation with very little power. Dual dichroic optics maintain a cool stage despite high light intensity, and internal baffles further increase brightness.

  • Patent number: 4912752
    Abstract: An optical projector having opaque and transparency operating modes employs a pair of illumination paths, conventional overhead-projection optics, common focus elements, and a large-aperture stage. Oversized objects such as large books or magazines are accommodated by a resilient bottom of a light-constraining hood assembly. A light source is oriented in a manner that eliminates optical or physical interferences between the pair of projection modes. The hood assembly provides novel reflectivity for image intensification in the opaque mode and easy access to the stage for either opaque or transparency projection. Most elements associated with either projection mode can be detached in a unit, leaving solely the remaining mode capability.

  • Patent number: 4578571
    Abstract: A compact, portable bar code scanner employing as a light source a light-emitting diode consumes extremely low input power. The scanner, which detects the reflectances from bars and spaces of the bar code symbol, uses optical beam-shaping methods to attain a large depth-of-focus for a non-laser system. A shaped illuminating light beam is caused to blink when the symbol is outside the depth-of-focus range and a signature imposed upon the light beam enables the scanner to substantially reject light interference. A scanning version employs an optical assembly mounted upon a bimorph leaf spring that is caused to vibrate at its natural mechanical resonance. The scanner operates with bar code symbols responsive to red light and is of sufficiently low weight to be easily hand-held.

  • Patent number: 4090299
    Abstract: An orthodontic appliance having an arcuate labial bar shaped to generally conform to the outer surface of a row of teeth and an arcuate lingual bar shaped for positioning on the inner surface of the same row of teeth. The two bars are held together and serve to urge the teeth located between the bars into a desired arcuate shape. Screw means are disclosed for attaching the labial and lingual bars and tapered screw means may be used whereby the further insertion of a tapered screw will tend to urge a tooth either away from or toward the center line of the jaw. The labial and lingual bars may be affixed to a collar or cap which may be attached to a molar or other tooth. A channel affixed to the lingual bar is disclosed whereby the nut for any screw may be held out of direct contact with the user's tongue. The labial and lingual bars may be attached by ratchet means located near the extremity of each bar.

  • Patent number: 4051721
    Abstract: An applied force whose mangitude is to be measured is caused to change the spacing between a pair of conductive plates. The resulting variation in capacitance between the plates is employed in an RC oscillator circuit so as to produce a frequency that is reciprocally related to the capacitance. A neutralizing circuit serves to cancel the effect of stray capacitance, and a digital counting device converts the oscillator frequency to a scaled number indicating the magnitude of the applied force.
