In some embodiments, an apparatus comprises a housing, an emitter, and an electronic circuit. The housing is configured to fit within a patient's mouth. The emitter is at least partially encased within the housing. The emitter is configured to emit an effective amount of light to the alveolar soft tissue when the housing is disposed within the mouth. The electronic circuit is operatively coupled to the emitter. The electronic circuit is configured to control the emitter when the housing is disposed within the mouth and the apparatus is in use during orthodontic treatment. The apparatus and its use for regulating tooth movement or maintaining or improving oral tissue health are disclosed herein.

Intra-oral light-therapy apparatuses and methods for their use

Methods for accelerating orthodontic movement that include administering, within first and second consecutive time periods, light via an intraoral light therapy apparatus having a mouthpiece, are provided herein. During administering, the mouthpiece is disposed within a mouth of a patient, with a light emitter embedded in a flange of the mouthpiece being disposed between alveolar mucosa and buccal mucosa of the patient. A first removable aligner is disposed on a first set of teeth of the patient prior to, during, or subsequent to a first administering. A second removable aligner, different from the first removable aligner, is disposed on a second set of teeth of the patient prior to, during, or subsequent to a second administering. The light directly illuminates a first portion of the alveolar mucosa during the administering.

A non-contact fader control uses a movable permanent magnet and one or two Hall-effect sensors to provide a constant, direct current voltage output. Signal conditioning and digital control circuitry linearize the output and otherwise precondition the output for application to a voltage controlled amplifier for the control of audio output in an audio mixing board.

Non-contact audio fader control system and method

Collision avoidance apparatus ( ) is mounted on a host vehicle ( ) to detect the presence of an adjacent vehicle ( ) within a monitored zone ( ). A sensor module ( ) includes a plurality of discrete sensor systems for monitoring unique portions of the monitored zone ( ), each of which comprises an emitter ( ) emitting a fixed frequency modulated beam ( ) of light energy ( ) with a predetermined burst length into its unique portion of the monitored zone ( ), and a receiver ( ) having a field of view ( ), substantially aligned with emitted beam ( ) to produce a fixed optical overlap area (A), and for sensing light energy ( ) and generating a received signal. A frequency generator ( ) produces two or more predetermined different fixed frequencies for use by the emitter ( ) to emit beams ( ) at each frequency. A phase shifter ( ) produces a phase shifted reference signal with a different predetermined phase delay relationship to each fixed frequency. A mixer ( ) mixes each received signal and each phase shifted reference signal to produce demodulation signals from for each frequency. A processor ( ) receives and processes accoupled logic level detection signals generated by a limiter amplifier ( ) for each discrete sensor system at each of the fixed frequencies to determine the presence of a vehicle ( ) in the monitored zone ( ). The fixed frequency and the predetermined phase delay are chosen to produce a null received signal resulting from reflections of the emitted beam from uniformly distributed atmospheric backscatter within the optical overlap area (A).

Multi frequency photoelectric detection system

A method of defining a sensing system for detecting the presence of an object in a volume of space under surveillance by determining the optimal placement of a plurality of energy beams which are projected into the volume which comprises the steps of (A) placing the object at a preselected position within the space; (B) directing a plurality of sample beams of energy, which have a predetermined orientation, from a source onto the object; (C) detecting the reflections of the sample beam energy from points on the object by energy detectors; (D) recording the preselected position of the object, the predetermined orientation of sample beams, and the detection status of the energy detectors; (E) changing the equatorial and azimuthal angles of each of the beams and repeating steps (B), (C) and (D); (F) moving the source of the sample beams relative to the object; (G) repeating steps (B) through (F) to produce spatial maps of the locations at which the object is positioned when each of the energy detectors detect reflected sample beam energy; and (H) using the spatial maps so produced to select the optimal orientation of a set of energy beams which will maximize the detection probability of an object located in the volume of space under surveillance. This method is repeated for a plurality of different vehicles.

Method of determining optimal detection beam locations using reflective

A method and apparatus are disclosed which allow for the detection of an object (14) by the generation of a radiated beam (18) and a subsequent reflection by the object (14) of a portion (20) thereof. The detection of particulate object material (16) due to a reflection of a portion (22) of the generated beam (18) is minimized.
