Extended optical range reflective system for monitoring motion of a member
A garment and system includes a monitoring fabric that exhibits a light reflection property and substantially no light transmission property when the fabric is illuminated with light having wavelength(s) in the range of 400 to 2200 nanometers. The amount of useful light reflected by the fabric into an aperture of acceptance defined with respect to an axis extending from the fabric relative to the amount of light lost to the aperture of acceptance detectably changes when the fabric stretches in response to motion, as the motion induced by physiological activity (e.g., heart rate). The system includes at least one radiation source and at least one radiation detector, with the detector disposed in the aperture of acceptance. The source and detector may be attached to the fabric in relative positions such that the reception of incident radiation by the detector is directly affected by a change in the amount of useful light reflected by the fabric into the aperture of acceptance as the fabric stretches in response to motion.

An advanced reflexive structure system is disclosed. The reflexive system mimics the pain withdrawal reflex on which the human body relies. The reflexive system incorporates a continuous health and performance monitoring system via an embedded dielectric film, an adaptive composite structure based on shape memory composite material, and an intelligence system which will be interfaced with both the health / performance sensors and the adaptive structure. When activated shape memory polymer will recover its structural integrity via shape recovery and a reptation healing process. These features enable the use of SMP as an adaptive structure in the proposed reflexive system. The development of a reflexive system for structures will enable increased safety and security and demonstrate a better understanding of integrated performance systems. This reflexive technology could find immediate implementation on all current and future systems and future implementation on platforms such as the International Space Station, Lunar, and Martian habitats.

Complete autorefractor system in an ultra-compact package
An autorefractor system in an ultra-compact package is described for rapidly and objectively measuring the refractive state of the eye. The autorefractor detector system, in conjunction with a secondary light source, uses one photodetector such as a charge coupled device ("CCD") or one photodiode, to intercept a light beam at two distances from a secondary retinal light source created by one relay lens, one pupil emitter conjugate lens and one pupil detector conjugate lens. The signals produced by the photodetector are used to determine the full spherocylindrical refraction of the eye. A novel illumination and imaging system provides multiple capabilities to image the eye, control accommodation, and acquire and maintain optical alignment, while obtaining other measurements of the eye.

Lithographic apparatus having double telecentric illumination
A system and method are used to pattern illumination to form one or more devices on a substrate using a reflecting system, a pattern generator that defines an objection plane, a projection system, and the substrate that defines an image plane. A reflecting portion of the reflecting system is substantially parallel to a reflecting portion of the pattern generator. The reflecting portion of the pattern generator patterns the illumination beam and directs the patterned illumination beam towards the substrate via the projection system. Based on the relationship of the reflecting system and the pattern generator, the illumination beam is telecentric proximate the object plane and the patterned illumination beam is telecentric proximate the image plane. Through use of a reflecting optic and not a transmissive optic to direct light between the illuminator and the projection system, illumination efficiency is increased and errors imparted on the illumination are decreased.
