20130026233 | IMAGER EXPOSURE, ILLUMINATION AND SATURATION CONTROLS IN A POINT-OF-TRANSACTION WORKSTATION - An illumination time of an illumination system and/or an exposure setting of an imaging system are adjusted by a proximity system operative for detecting a product entering a field of view in a bi-optical, dual window, point-of-transaction workstation. The proximity system includes an infrared emitter for emitting infrared light to the product, and an infrared sensor for sensing return infrared light from the product. Multiple predefined thresholds are stored for the sensed return infrared light, and a predefined illumination time and/or exposure setting are stored and assigned to each predefined threshold. Adjustment of the illumination time and/or of the exposure setting is performed by comparing the sensed return infrared light from the product in real time operation with the stored predefined thresholds. | 01-31-2013 |

20130134220 | APPARATUS FOR AND METHOD OF UNIFORMLY ILLUMINATING FIELDS OF VIEW IN A POINT-OF-TRANSACTION WORKSTATION - Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield. | 05-30-2013 |

20150233616 | HEAT PUMP OF HEAT SOURCE TOWER FOR REALIZING SOLUTION REGENERATION AND HEAT REUTILIZATION BASED ON VACUUM BOILING - The disclosure provides a heat source tower heat pump realizing solution regeneration and heat reutilization based on vacuum boiling. It comprises a refrigerant circuit, a solution circuit, a vacuum maintenance circuit, an air circuit, a regenerative solution heating circuit and a cold/hot water circuit. The unit provided by the disclosure regenerates a solution by taking full advantage of the characteristic that the boiling point of a solution will be reduced in vacuum, uses the heat released from the cooling of overheated refrigerant as the heat of solution regeneration and also uses the heat to produce heat supply hot water. While significantly raising the speed of solution regeneration, it also realizes efficient reutilization of solution regeneration heat, thoroughly solves the problem of solution regeneration of the heat pump of heat source tower system, improves the safety and reliability of the heat pump of heat source tower system in various operating conditions and realizes high overall efficiency of the system. | 08-20-2015 |
