Abstract: A phase change material (PCM) module heat exchanger assembly includes a multi-section PCM container rotatingly supported about a center long axis of the multi-section PCM container, or a multi-section PCM container where one or more sections are slidingly mounted to the multi-section PCM container. Each section of a plurality of rotatably or slidingly selected PCM sections is selectably insertable into an air flow. A method of placing one of a group of two or more PCM sections into a building's heating, ventilation, or air conditioning (HVAC) ductwork and a method to harvest heating or cooling capacity for later use are also described.

Abstract: A low noise micro environmental workspace comfort unit for a workspace provides an air flow to a person working at the workspace. At least one ambient air fan is mounted to a wall of the comfort unit enclosure and electrically coupled to a fan speed control module, the fan speed control module operatively coupled to the controller. At least one heated air fan is mounted to the wall or another wall of the comfort unit enclosure at a different place than the at least one ambient air fan. A heat reflector reflects heat radiation away from a rear portion of the low noise micro environmental workspace comfort unit and directs an air flow from the at least one heated air fan to the at least one air outlet. A method for minimizing fan noise of a low noise micro environmental workspace comfort unit is also described.

Abstract: A drive arrangement for a hybrid vehicle includes an internal combustion engine with a takeoff shaft; an electrical machine with a rotor and a stator; a first and a second clutch, each with an input part and an output part; and a housing, which surrounds at least the clutches and the electrical machine.

Abstract: A method and system for rendering three-dimensional graphics, including text, provide a compressed texture bitmap. The texture bitmap may represent multiple symbols, each comprised of multiple pixels. Each pixel in the texture bitmap may store information for more than one symbol, including compressed pixels corresponding to multiple distinct symbols. For example, the compressed texture bitmap may have n-bit pixels (e.g., 8-bit pixels) that each store m (e.g., four) n/m-bit (e.g., 2-bit) compressed values. The compressed texture bitmap may be configured for unpacking by a conventional pixel shader, such as a pixel shader that does not typically perform bitwise operations. The unpacking may include matching a fetched pixel to a value in a lookup table, such as a 32-bit value from a 256-color palette. The looked-up value can be separated into separate sub-values to facilitate processing by the pixel shader.

Abstract: A method and system for rendering three-dimensional graphics, including text, provide a compressed texture bitmap. The texture bitmap may represent multiple symbols, each comprised of multiple pixels. Each pixel in the texture bitmap may store information for more than one (e.g., n) compressed values, including pixels corresponding to multiple distinct symbols. For example, the compressed texture bitmap may have n-bit pixels (e.g., 8-bit pixels) that each store m (e.g., eight) 1-bit values. The compressed texture bitmap may be configured for unpacking by a conventional pixel shader, such as a pixel shader that does not typically perform bitwise operations. The unpacking may include matching a fetched pixel to a mapping value in a lookup table, such as a 32-bit value from a 256-color palette. The looked-up value can be separated into separate sub-values to facilitate processing by the pixel shader. For example, the looked-up value can be split into RGBA values conventionally used in processing colored pixels.

Abstract: A method and system for rendering three-dimensional graphics, including text, provides a compressed texture bitmap. The compressed texture bitmap may represent multiple symbols, each comprised of multiple pixels. Each pixel in the texture bitmap may store information for more than one value, including values for compressed pixels corresponding to multiple distinct symbols. For example, the compressed texture bitmap may have n-bit pixels (e.g., 16-bit pixels) that each store up to m (e.g., four) n/m-bit (e.g., 4-bit) compressed values. Multiple pixels can be stored in a single texture using, for example, distinct red, green, blue, and alpha (RGBA) channels associated with each pixel. The compressed texture bitmap may be configured for unpacking by a conventional pixel shader, such as a pixel shader that does not typically perform bitwise operations. The unpacking may include isolating a pixel associated with a desired value using a masking operation in the pixel shader.

Abstract: A rack or shelf for a floral display cabinet has a scalloped cutout that holds a number of round or conic vases or flower containers. The scalloped shape allows the containers to be held in a number of configurations. The containers do not shift or slide if the merchandiser is bumped or moved. The tip or pitch angle of the shelf can be adjusted. A cover for the shelf allows the shelf to be used as a solid flat shelf for supporting items from the bottom.
