Abstract: A coffee brewer advertising and marketing system includes a beverage brewer having a touch-screen display and at least one user-identification sensors, a beverage cup containing a pre-brewed beverage, a brewer lever that is lowered for piercing the beverage cup, and a pre-programmed RFID chip provided on the beverage cup. The beverage brewer has an RF reader that reads the RFID chip embedded on the beverage cup for ensuring that only authorized beverages provided in approved beverage cups are dispensed by the beverage brewer.

Abstract: A cover for the protection of large bolts and nuts, such as those used to secure wind turbine towers to foundations, from the weather. The protective cover may be tubular in shape and designed to be forcefully pressed over the bolt while ribs on the interior of the cover form an interference fit with the threading on the bolt. A larger portion located at the bottom of the cover protectively surrounds the nut and washer without touching either. The bottom can then seal against a surface, such as the surface of a mounting flange of a tower, to prevent the entry of corroding moisture.

Abstract: A single layer roofing material having a headlap portion and a tab portion wherein the headlap portion has a color-value gradient or gradation and the tab portion has tabs and openings. The tabs may have a relatively uniform color. Openings between tabs expose the color gradient of the headlap portion when a first sheet of the roofing material is installed over a second sheet on a structure. A plurality of horizontal striations may be used to establish the desired color-value gradient. An illusion of depth or thickness is created when the roofing material is applied to a structure, such as a roof deck. The amount of tone and contrast may be selected to create the desired illusion of depth or thickness. The amount of contrast may be varied depending upon the color selected for each roofing material. The number of horizontal striations and their width may also be varied to provide the desired color-value gradient. Tab color, shape and size may also be varied to enhance the illusion of depth.

Abstract: A heat exchanger subsystem for an environmental control system comprises a heat exchanger array having a plurality of heat exchanger elements that operate in parallel to an inlet cooling airflow to the heat exchanger array such that each load heat exchanger is connected to a separate load with each heat transfer loop operating in substantially independent fashion without load interaction effects. In addition, continuous ice and water removal is provided allowing continuous subfreezing operation improving cooling performance along with anti-ice provisions which recover rejected heat for improved energy efficiency. The heat exchanger elements may include air-to-air heat exchanger cores, liquid-to-air heat exchanger cores, and hot bars internal or external to the heat exchanger cores.

Abstract: Apparatus and method of producing a halftone image reproduction of a continuous tone photograph. Scanning means is provided to scan the photograph to be reproduced along a series of scan lines. Incremental control parameters are provided in accordance with a reproduction ratio to define predetermined scan sample points for each scan line. Control means is provided for controlling the scanning means to produce successive sets of digital sharp and unsharp gray level data signals at the predetermined scan sample points proportional to the light reflected from successive concentric sharp and unsharp areas with the sharp area at each scan sample point corresponding to the general area of a predetermined portion of a halftone cell.
