| 20120043907 | COMPACT HIGH BRIGHTNESS LED GROW LIGHT APPARATUS, USING AN EXTENDED POINT SOURCE LED ARRAY WITH LIGHT EMITTING DIODES - A compact high-brightness LED grow light fixture is described for use in growing plants under artificial light, or as a supplement to natural sunlight. The LED grow light uses a densely-packed array of high-brightness light emitting diodes (LEDs) that are not individually packaged where the array behaves similarly to a point source of light. The LED chips are distributed laterally over an area, where the LED chips have light emitting surfaces for emitting light in directions transverse to said area, wherein the dimensions of the area do not exceed 25 mm. Adjacent chips of the array are preferably separated by less than about 0.2 mm. The extended point source LED array, with its lens and associated reflector, result in a concentrated, partially-collimated light source, such that the intensity of the light does not diminish rapidly as distance from the light source increases. Thus, foliage that is lower down on the plant will receive almost as much light energy as does foliage on the top of the plant. The compact LED grow light does not block much of the natural sunlight, making the LED grow light suitable for use as a supplement to natural sunlight. The LED array contains a plurality of LED strings that may be separately controlled, thereby allowing the spectral content of the LED grow light to be varied, to facilitate desired plant growth at various stages of plant life. Multiple wavelengths of LEDs may be used within each LED string, thereby allowing the ability to further optimize the spectral content of the LED grow light. Due to the compact size of the LED grow light, the light emitted at each of the multiple different wavelengths from the array is evenly distributed, when the objects being illuminated by the array are at a distance of less than about 6 feet or even less than 1 foot from the array. Flexible mounting options allow for the use of multiple compact LED grow lights within a single plant growing area, and also allow for side or bottom lighting of plant foliage, in addition to the more typical overhead lighting. | 02-23-2012 |
| 20120044713 | Compact High Brightness Led Aquarium Light Apparatus, Using an Extended Point Source Led Array with Light Emitting Diodes - A compact high-brightness LED aquarium light fixture is described for use in illuminating aquarium tanks artificial light. The LED aquarium light uses a densely-packed array of high-brightness light emitting diodes (LEDs) that are not individually packaged, where the array behaves similarly to a point source of light. The LED chips are distributed laterally over an area, where the LED chips have light emitting surfaces for emitting light in directions transverse to said area, wherein the dimensions of the area do not exceed 25 mm. Adjacent chips of the array are preferably separated by less than about 0.2 mm. The extended point source LED array, with its lens and associated reflector, result in a concentrated light source that attractively illuminates the contents of the aquarium, and creates a desirable shimmering effect within the aquarium. The compact LED aquarium light does not block much of the top surface area of the aquarium, thereby allowing unimpeded access to the top of the aquarium for viewing the aquarium, and also for tasks such as feeding, tank cleaning, and other aquarium maintenance. The LED array contains a plurality of LED strings that may be separately controlled, thereby allowing the spectral content of the LED aquarium light to be varied, to facilitate desired aquarium viewing conditions, as well as promoting the growth, health, and other desired attributes of various forms of marine life such as marine plants, algae, and coral. Multiple wavelengths of LEDs may be used within each LED string, thereby allowing the ability to further optimize the spectral content of the LED aquarium light. Due to the compact size of the LED aquarium light, the light emitted at each of the multiple different wavelengths from the array is evenly distributed, when the objects being illuminated by the array are at a distance of less than about 3 feet or even less than 1 foot from the array. A clamp-on, flexible gooseneck mounting arrangement allows for the use of one or more compact LED aquarium lights with aquarium tanks of various sizes and dimensions. | 02-23-2012 |

| 20100070938 | Preconditioning For EDA Cell Library - A characterized cell library for EDA tools includes one or more mathematical models for each cell, and one or more preconditioning functions (and/or inverse preconditioning functions) for each mathematical model. Each mathematical model represents a performance parameter (e.g., delay, power consumption, noise) or a preconditioned performance parameter of the cell. The preconditioning functions convert an operating parameter (e.g., input slew, output capacitance) associated with the performance parameter into a preconditioned input variable for the mathematical models. In doing so, the preconditioning functions allow for more accurate modeling of complex data relationships without increasing the complexity (e.g., order and number of coefficients) of the mathematical models. Also, because the cell library can be substantially similar to conventional polynomial-based cell libraries except for the inclusion of preconditioning functions, preconditioning does not significantly increase storage requirements and conventional EDA tools can be readily adapted to use the preconditioned cell library. | 03-18-2010 |

| 20090052395 | Femto-BTS RF access mechanism - Femto cells that extend mobile network coverage into customer premises operate in a frequency band typically assigned to a macro network. As disclosed, to facilitate system discovery and registrations of mobile stations with femto cells, a carrier designates one the channels within the band as a primary channel for its femto cells. For example, neighbor list messages transmitted by macro network base stations can provide frequency and PN code information directing mobile stations to search the primary channel for a PN code of the femto cells. Also, a mobile station PRL may identify femto cells by SID/NID. The SID is that of the carrier's macro network, whereas the NID may be a NID of the macro network or one specifically assigned to femto cell operations. The PRL uses frequency acquisition information for the femto cells that is the same as or similar to that for one of the macro networks. | 02-26-2009 |

| 20090119281 | Granular knowledge based search engine - The application borrows terminology from data mining, association rule learning and topology. A geometric structure represents a collection of concepts in a document set. The geometric structure has a high-frequency keyword set that co-occurs closely which represents a concept in a document set. Document analysis seeks to automate the understanding of knowledge representing the author's idea. Granular computing theory deals with rough sets and fuzzy sets. One of the key insights of rough set research is that selection of different sets of features or variables will yield different concept granulations. Here, as in elementary rough set theory, by “concept” we mean a set of entities that are indistinguishable or indiscernible to the observer (i.e., a simple concept), or a set of entities that is composed from such simple concepts (i.e., a complex concept). | 05-07-2009 |

| 20110246489 | HASHING ALGORITHM FOR NETWORK RECEIVE FILTERING - Roughly described, a network interface device is assigned a maximum extent-of-search. A hash function is applied to the header information of each incoming packet, to generate a hash code for the packet. The hash code designates a particular subset of the table within which the particular header information should be found, and an iterative search is made within that subset. If the search locates a matching entry before the search limit is exceeded, then the incoming data packet is delivered to the receive queue identified in the matching entry. But if the search reaches the search limit before a matching entry is located, then device delivers the packet to a default queue, such as a kernel queue, in the host computer system. The kernel is then responsible for delivering the packet to the correct endpoint. | 10-06-2011 |
