In accordance with a first exemplary embodiment of the present disclosure, a mounting arrangement for use with an LED power strip module is provided. The mounting arrangement comprises one or more one frames having a first end and a second end, a first holding base configured to mate with the first end and a second holding base configured to mate with the second end, and at least one LED module having a first and second edge and comprising a plurality of LEDs, said LED module being adapted to removably attach to the one or more frames. The first and second holding bases are adapted to secure the one or more frames to an existing raceway structure.

Computer operations are partitioned for execution by a processor. A plurality of operations to be partitioned is received. The respective priorities for each of the plurality of operations is determined. Ready operations are identified, where a ready operation is an operation that does not have any predecessor operations that have not yet been added to a partition. A determination is made whether adding the ready operations with the highest priorities to the current partition would violate a hardware resource constraint. Based on this determination, the ready operations are added to the partition. The operations added to the partition are provided to a processor for execution.

A method of making a bipolar plate includes molding a non-conductive housing defining a plurality of receiving areas. A first plurality of conductive charges are located into each of the plurality of receiving areas. Compressive force is applied to each of the first plurality of conductive charges thereby defining a first plurality of conductive plates bonded on outer edges to the non-conductive housing. A second plurality of conductive plates are located onto the first series of conducive plates. The first and second plurality of conductive plates are bonded together defining a coolant flow field therebetween.

The present invention provides improved systems and processes for performing sequential batch anaerobic composting (SEBAC) on high solids content wastes. In particular, the present invention provides improved flooded SEBAC systems that function more efficiently (i.e., higher conversion kinetics) at lower temperatures than conventional SEBAC systems. Further, the improved flooded SEBAC systems and processes of the subject invention enable efficient anaerobic digestion operation at a smaller reactor volume ratio as compared to conventional SEBAC systems, without the displacement of leachate and clogging as a result of entrapped biogas or an increased pressure drop (hydraulic). Further, the improved flooded SEBAC systems of the invention overcome concerns associated with leachate displacement as well as excessive pressure drops.
摘要:
A processor implements conditional vector operations in which an input vector containing multiple operands to be used in conditional operations is divided into two or more output vectors based on a condition vector. Each output vector can then be processed at full processor efficiency without cycles wasted due to branch latency. Data to be processed is divided into two groups based on whether or not they satisfy a given condition by, e.g., steering each to one of two index vectors. Once the data has been segregated in this way, subsequent processing can be performed without conditional operations, processor cycles wasted due to branch latency, incorrect speculation or execution of unnecessary instructions due to predication.
摘要:
A lighting system generally includes a plurality of electrically interconnected modules. Each module includes a support, circuitry on the support, at least two light emitting diodes (“LEDs”) on the support and electrically connected to the circuitry, and a housing over the support for covering the circuitry. A first LED on a first surface of the support emits light in a first general direction and a second LED mounted on a second surface of the support emits light in a second general direction, which is opposite the first general direction.

The present invention relates to an electrically conductive element, such as a bipolar plate, for a fuel cell which has an improved adhesive bond. The conductive element generally comprises a first and a second conductive sheet, each having a surface that confronts one another. The first and said second coated surfaces are joined to one another by an electrically conductive epoxy adhesive which provides adhesion of the first and said second surfaces of the sheets at one or more contact regions.
