Abstract: A processor-based device for displaying simulated or modeled surface appearances based on surface color and surface texture data stored in a data storage. By selecting different combinations of color and texture, different surface appearances may be modeled and displayed. Also, the device may comprise an orientation sensor. Accordingly, the device may additionally consider the orientation of the device when generating surface appearances.

Abstract: A system (100) for sensing a temperature of a light emitting diode (LED). The system may comprise an LED having a spectral output centered at a first wavelength, a first filter (104) that transitions from attenuation to transmission at about the first wavelength, and a second filter (106) that transitions from transmission to attenuation at about the first wavelength. The system may also comprise a first sensor (108) positioned to sense a first intensity of the LED through the first filter and a second sensor (110) positioned to sense a second intensity of the LED through the second filter. It will be appreciated that a single sensor may be substituted instead of the first and second sensors, provided that the single sensor is capable of selectively viewing the LED through the first and the second filters. The system may also comprise a computer (112) configured to derive a temperature of the LED considering the first intensity and the second intensity.

Abstract: An optical assembly is disclosed that includes an illumination source, a detection sensor, a monitor sensor, and an optical piece having a first side adapted to face a sample. The optical piece defines an illumination channel extending from the illumination source toward the first side, a detection channel extending from the first side toward the detection sensor, and a monitor channel extending from the illumination channel toward the monitor sensor. A spectrophotometer is also disclosed that includes a circuit board, illumination source and one or more sensors. The circuit board includes an optically transparent region, wherein the illumination source is mounted and situated relative to a first surface of the circuit board, so as to direct light through the optically transparent region. Each sensor is mounted and situated relative to a second surface of the circuit board opposite the first surface.

Abstract: An apparatus, system and method for targeting an image formed on an imaging member. The imaging member includes an imaging sensitive layer formed thereon. The imaging member includes imaged and non-imaged areas. Light of a predetermined wavelength reflected from a target area of the imaging member is received. The light reflected from the target area is representative of an image formed on the imaging sensitive layer using energy at approximately the predetermined wavelength. The predetermined wavelength is suitable to initiate crosslinking of the imaging sensitive layer.

Abstract: There is disclosed a compact lens system having four injection-molded singlet lens elements with one of the singlet lens elements having a diffractive optical surface to control axial chromatic aberrations and another of the singlet lens elements having a flint-like plastic material to control lateral chromatic aberration. The lens system includes interdigitated flange features which provides interdigitated alignment between the lens elements. A plurality of light suppression elements are used to suppress stray light paths from reaching a detector array of the lens system. Moreover, the lens system includes an anti-aliasing surface on one of the lens elements for controlling aliasing effects.

Abstract: A utility emergency light assembly for vehicles, machinery, or the like detachably mounted by a slide coupling to a mounting bracket attached to the vehicle or machine. The light assembly has a compact, space-saving profile and includes a housing having a lamp assembly mounted within a spool journaled in the housing for reeling and unreeling a power cord, enabling movement of the assembly to areas of the vehicle where light is needed. A cap substantially closes the housing and includes a lens located over the lamp assembly. The lamp assembly is sealed within the spool, while the remainder of the housing is open to allow water drainage and to prevent the accumulation of moisture and debris.
