Abstract:
A method and apparatus for a document filtering mechanism is provided. A document indexing mechanism is described. A first document is parsed into elements, and a deterministic pseudo-random score is calculated for at least some of the elements. A subset of the scores is selected based on the values of the scores. The subset of the scores is used as multiple indexes into a database of documents.
Method For Controlling The Temperature Of An Led Luminaire
Methods for controlling temperature in an LED luminaire are disclosed. The LED luminaire has one or more sets of LED light engines disposed on a printed circuit board (PCB), some or all of which are activated in response to an instruction or set of instructions. A temperature of the PCB is measured in at least one location. If the temperature exceeds a threshold, the duty cycle of active sets of LED light engines is ramped down uniformly over time.
