Abstract: The invention relates to a method and a device for detecting the presence of an ophthalmic molding consisting of a biocompatible polymeric material, especially an ophthalmic lens, particularly a contact lens, in a package. The invention solves the problem through the use of a spectroscopic process. Packages containing a molding, especially a contact lens, have a characteristic change in their measuring spectrum compared with a package without a contact lens. By evaluating the spectra, it is possible to determine whether or not there is a contact lens in a package. In particular, by using the measuring method according to the invention, one can determine directly after the filling procedure whether there is a contact lens in the package. In addition, the invention is suitable for checking whether contact lenses are contained in the already sealed package. During this procedure, the package remains intact.

Abstract: A body temperature detector is particularly suited to axillary temperature measurements of adults. The radiation sensor views a target surface area of the body and electronics compute an internal temperature of the body as a function of ambient temperature and sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature to account for varying perfusion rate. Preferably, the coefficient varies from a normal of about 0.13 through a range to include 0.09. The ambient temperature used in the function is assumed at about 80null F. but modified with detector temperature weighted by 20%.

Abstract: A system for providing recognition of an approaching object located in a distant no-light environment includes an illumination source for transmitting light to the distant object and an imaging device for detecting the light radiation reflected from the distant object to generate an image of the distant object corresponding thereto. The system also includes an independent digital signal processor for calculating a desired optical magnification of a lens of the imaging device as a function of a distance between the imaging device and the distant object and generates a voltage corresponding thereto. The digital signal processor applies the voltage to the digital zoom circuitry of the imaging device to adjust the magnification of the lens so that the image of the distant object is held in a fixed dimension.

Abstract: A device for the non-contact temperature measurement on an object comprises a detector device with a detector and IR optics, which image the detector along a measuring beam path with an optical axis onto a measuring spot on the object, and a sighting device for the visualization of the measuring spot with a light source for the creation of marking light and ring optics, which form a marking beam path that surrounds the outer circumference of the measuring beam path. The marking light is aligned so that on each location of the marking beam path its cross section, vertical to the optical axis, forms a circular ring surface.

Abstract: The invention generally relates to optical imaging systems and methods for providing images of two-dimensional or three-dimensional spatial or temporal distribution of properties of chromophores in a physiological medium. More particularly, the following description provides preferred embodiments of optical imaging systems utilizing efficient, real-time image construction algorithms. A typical optical imaging system includes at least one wave source, at least one wave detector, a movable member, an actuator member, and an imaging member. The wave source emits electromagnetic waves into a target area of the medium, and the wave detector detects electromagnetic waves and generates output signal in response thereto. The movable member includes the wave source and/or detector, and the actuator member moves the movable member along with the wave source and detector over different regions of the target area while the wave detector generates the output signal therefrom. The imaging member generates a set of voxels in the target area and calculates voxel values each of which represents a spatial or temporal average of the property of the chromophore in each voxel. The imaging member generates a set of cross-voxels from the intersecting voxels, and calculates cross-voxel values of the cross-voxels directly from the voxel values of the intersecting voxels. The imaging member then constructs the images of the chromophore properties in the target area. Accordingly, without needing to resort to the time-consuming conventional image reconstruction methods, the optical imaging system of the present invention can construct such images on a substantially real time basis.

Abstract: A process for the detection of flaws in an article comprising infra-red scanning of the article as its temperatures changes and comparing the infra-red scans for regularity of cooling/heating pattern. Where the article is irregular, such as in marginal areas, thermodynamic modelling is performed to establish a hypothetic cooling/heating pattern for an unflawed article.
