Abstract:
A thermal printhead incorporating an elongated heat conduction chamber which is oriented in alignment with an array of printhead heating elements and used to transfer heat along the array to equalize heat distribution. The chamber contains a heat transfer fluid and wicks. The fluid when in a liquid state absorbs heat at a hot spot along the array through evaporation, transports the heat along the array to cooler portions of the chamber as a gas through gas dynamics and localized pressure, condenses to the liquid form, and returns to the hot spot through the capillary action of the wicks. In another embodiment, a metal strip is used to distribute the heat along the heating element array between hot and cool portions of the array.
Abstract:
A thermal recording paper comprising a substrate (12) and a protective layer (20). The substrate includes a support layer (13) and a thermal layer (14) comprising a heat-sensitive, image forming thermal material. The protective layer comprises a cured silicone resin overlying one side of the substrate and positioned on the same side of the support layer as the thermal layer. In another aspect, the present invention comprises a method of making thermal recording paper comprising coating one side of the substrate with a silicone resin such that the silicone resin is positioned on the same side of the support layer as the thermal layer, and curing the silicone resin by exposing it to radiation such as electron beam radiation or ultraviolet radiation.

Abstract:
An integrated photonics module includes at least one light source and a MEMS scanner coupled to and held in alignment by an optical frame configured for mounting to a host system. According to some embodiments, the integrated photonics module may include a plurality of light sources and a beam combiner coupled to the optical frame. According to some embodiments, the integrated photonics module includes a selective fold mirror configured to direct at least a portion of emitted light toward the MEMS scanner in a normal direction and pass scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.

Abstract:
Apparatuses and methods for scanned beam imagers and scanned beam endoscopes that utilize multiple light collectors are disclosed. In one aspect, a scanned beam imager is disclosed. The scanned beam imager includes a scanned beam source operable to scan a beam onto a region of interest of an object. The scanned beam imager further includes a first light collector structured to collect light reflected from the region of interest and a second light collector positionable relative to the scanning tip. The second light collector structured to collect light transmitted through the region of interest.
Abstract:
Aspects of the subject matter described herein relate to improving images obtained from an image-acquiring system (e.g., such as a scanned laser beam camera, a scanned laser imager, or other image-acquiring system). In certain aspects, an image frame is obtained from which a histogram is created. Characteristics of the image are determined based on the histogram. These characteristics are used to make an image quality judgment regarding the image. This judgment is then used to adjust parameters in the image-acquiring system for obtaining a subsequent frame. Parameters may be adjusted even if the image is judged as normal. Other aspects are described in the specification.
Abstract:
A scanned beam imager or laser scanner is operable to scan an object moving through its field-of-view. The system may include means for detecting direction and/or speed of the object. The velocity detection means may include sensors, an interface for receiving velocity information from other system elements, or image analysis that examines the skew, stretch, or compression in images. Responsive to object movement direction and speed, the scanned beam imager may alter its pixel capture rate and/or its scan rate to compensate. Alternatively or in combination, the imager may perform software-based image motion compensation. In some embodiments, the system may allow the image capture region to pace objects moving rapidly through its field-of-view.
