Abstract: The present invention is directed to an electrical wiring protection device that includes a housing assembly having a plurality of line terminals and a plurality of load terminals. A fault detection circuit is coupled to at least one of the plurality of line terminals and configured to generate a fault detection signal in response to detecting at least one fault condition in the electrical distribution system. A circuit interrupter is coupled to the fault detection circuit, The circuit interrupter is configured to couple the plurality of line terminals to the plurality of load terminals to form a conductive electrical path in a reset state, and decouple the plurality of line terminals from the plurality of load terminals in response to a fault detection signal in a tripped state. A voltage transient suppression circuit is coupled to at least one of the plurality of line terminals.

Abstract: The present invention is directed to an electrical wiring system that includes a plug device having a plurality of wires configured to be connected to an electrical distribution circuit. An electrical wiring device includes an input receptacle and at least one electrical element. The input receptacle is configured to receive the plug device to thereby establish electrically a continuous path between the at least one electrical element and the plurality of wires when the plug device is inserted into the input receptacle, the electrical wiring device including no external terminal connection elements.
Abstract: A method and apparatus related to enhancing corneal accommodation to address the effect of presbyopia. Corneal/scleral topology measurements in accommodating and non-accommodating states are indicative of a presbyopic subject's nominal corneal accommodative power. A desired accommodative power intended to improve on the effect of presbyopia can be determined, suggesting a selective biomechanical intervention in the corneal structure outside of the optical zone to create flexure regions. These flexure regions would allow enhanced corneal accommodation upon presentation of an accommodating stimulus. Intervention could be in the form of, for example, corneal surface ablation, intrastromal ablation, conductive keratoplasty (CK), laser thermal keratoplasty (LTK), and corneal and/or scleral implants. An improved topology measuring apparatus having an improved field of view and other attributes is disclosed.

Abstract: Methods and apparatus for improving vision incorporate the effects of biodynamical and biomechanical (biological) responses of the eye. The eye produces a biological response to trauma, such as a LASIK keratectomy or other necessary traumatic procedure in preparation for refractive surgery. By observing the biological response, a prospective treatment to correct higher order aberrations is adjusted to compensate for the biological effects. An improved photorefractive surgery system incorporates one or more suitable diagnostic devices that provide biological response information in such a manner that the patient need not change position from that assumed for the surgical procedure.

Abstract: A binary optical compound formed from a preparation of proteorhodopsin, is provided. The preparation is prepared by dissolving proteorhodopsin in distilled water, where the pH is adjusted to be above 11 either by using sodium hydroxide or an appropriate buffer. The preparation is then illuminated with either white light sources, lasers, or irradiation provided from light-emitting diodes. The necessary duration is intensity dependent, varying from a few seconds to a few minutes, depending upon the source and actinic wavelength. The resulting compound has a long lifespan and may be efficiently transitioned between states.
Abstract: The present invention is directed to a computerized method for identifying at least one pattern in source code. The method includes the step of parsing the source code to obtain data corresponding to at least one source code class. A plurality of search units are provided, each search unit being configured to evaluate a single verifiable property of the at least one source code class to a TRUE state or a FALSE state. At least a portion of the plurality of search units are arranged in at least one predetermined search sequence. The at least one source code class is evaluated by each search unit included in the at least one predetermined sequence.

Abstract: A pressable body is described possessing a flexural strength of at least 125 MPa and is flowable at about 850° C. to about 950° C. The body is composed of at least a glass matrix phase having a composition comprising Li2O and MgO. A dental article formed at least in part from the pressable body is also described. Associated methods are also described.
Abstract: Embodiments of the invention pertain to remote optical control of holding beam-type, optical flip-flop devices, as well as to the devices themselves. All-optical SET and RE-SET control signals operate on a cw holding beam in a remote manner to vary the power of the holding beam between threshold switching values to enable flip-flop operation. Cross-gain modulation and cross-polarization modulation processes can be used to change the power of the holding beam.
