摘要： A disposable arthroscope for examining the interior of a joint and for carrying out diagnostic and therapeutic procedures within the joint includes an elongated needle and a cap housing which has a base plate. The proximal end of the needle is mounted on the cap opposite the base plate, and the distal end of the needle extends outwardly from the cap. The needle is a hollow tube which surrounds an image guide and a bundle of illuminating fibers that extend through the tube. A lens is attached to the distal end of the image guide and is slightly angled relative to the longitudinal axis of the needle. The proximal ends of both the image guide and the bundle of illuminating fibers extend from the proximal end of the tube and through the cap for exposure at the surface of the base plate. The base plate of the disposable arthroscope is engageable with a camera and with a light source to position the camera in light communication with the image guide, and to position the light source in light communication with the bundle. With these engagements, the combination of disposable arthroscope, light source and camera generate a visual display of an object that is illuminated by the light source through the bundle of illuminating fibers.

摘要： A hand-held portable arthroscope has a camera assembly and a disposable scope assembly rotatably attached to the distal end of the camera assembly. A probe which includes a fiber optic image guide and a plurality of optical illuminating fibers is rotatably mounted on the scope assembly, and is insertable into a body for imaging the internal structure of the body. The illuminating fibers extend through the scope assembly and are connected in light communication with a quartz halogen lamp for illuminating the internal body structure being imaged. To gather light from the illuminated internal structure of a body into which the probe has been inserted, a GRIN rod is attached to the distal end of the image guide. The image guide is bent near its distal end to offset the axis of the GRIN rod from the axis of the camera assembly, to enhance the field of view of the arthroscope when the scope assembly, which supports the image guide with GRIN rod, is rotated. Focussing optics are mounted in the camera assembly in light communication with the image guide. These focussing optics are axially movable within the camera assembly for focussing the image from the image guide. Light which passes through the focussing optics enters a camera head which is also mounted in the camera assembly. The camera head is in turn electrically connected to a video display device for producing an image of the internal structure of the body.

摘要： An ophthalmic lens inspection system includes an illumination assembly which generates diffuse light and transmits the diffuse light through an ophthalmic lens disposed in an inspection position, the diffuse light having a diffusivity of between 30.degree. and 50.degree.. An imaging assembly generates a set of signals representing selected portions of the diffuse light transmitted through the ophthalmic lens in the inspection position. A moving mechanism supports the imaging and illumination assemblies for common movement relative to the contact lens, to bring a reference point into alignment with the center of the imaging assembly.

摘要： An optical fiber security system includes an optical emitter connected to one end of an optical fiber and a detector connected to the other end. A random signal generator triggers the emitter to output a light pulse signal through the fiber. This generator also simultaneously triggers the detector to receive the light pulse signal. A comparator compares the light pulse signal that is received by the detector with an optimum reference to adjust and conform the emitter output with the reference. Also, a monitor determines whether a particular identifiable characteristic of the light pulse signal is within a predetermined range of values. Whenever there is not a simultaneous emission and detection of the light pulse signal, or whenever the light pulse characteristic is outside the predetermined range of values, the system alarms.

摘要： A device, and a method for using the device, to generate discrete information about an environmental event includes an array of sensors. All sensors in the array have a determinable detection capability and, preferably, some of these detection capabilities are redundant while others are overlapping. The individual sensors are positioned in the particular environment to detect characteristics of the event from different perspectives. The outputs which are generated by the various sensors in the array are selectively segmented and joined to create a convolved pattern of data which explicitly and implicitly includes information about the characteristics of the event. The convolved pattern is then presented to a pattern recognition unit, such as a neural network, where the characteristics are interpreted from the convolved pattern to generate the desired discrete information about the environmental event.

摘要： A system for analyzing smoke has a plurality of units, wherein each unit includes an optical emitter for alternately directing horizontally and vertically polarized light along a beam path, and into a smoke cloud, to generate scattered light. A horizontally polarized detector and a vertically polarized detector are positioned at different locations, but at a same distance and scattering angle relative to the beam path. Each unit has a different wavelength. A computer receives signals from the detectors of all units, in response to each emitter, for analysis of the smoke.
