  • Patent number: 8334901
    Abstract: In one aspect, the present disclosure relates to a method for modulating a beacon light source in a light based positioning system. In some embodiments, the method includes selecting a modulation scheme for the light source, the modulation scheme periodically varying an output of the light source from a peak output level to a bottom output level, applying the modulation scheme to the light source, and adding a DC bias to the modulation scheme, the DC bias reducing the peak output level and increasing the bottom output level of the modulation scheme. In some embodiments, the peak output level is increased beyond an un-modulated output of the light source and an average output of the light source is substantially equal to the un-modulated output of the light source. In some embodiments, the peak output level includes an un-modulated output of the light source.

  • Patent number: 8334016
    Abstract: Metal silicates or phosphates are deposited on a heated substrate by the reaction of vapors of alkoxysilanols or alkylphosphates along with reactive metal amides, alkyls or alkoxides. For example, vapors of tris(tert-butoxy)silanol react with vapors of tetrakis(ethylmethylamido)hafnium to deposit hafnium silicate on surfaces heated to 300° C. The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250° C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.

  • Patent number: 8321848
    Abstract: The described embodiments present techniques for recovering from syntax errors. These techniques correct potential errors while preserving the shape of the parse tree, and the specific implementation of the techniques can be automatically generated from the grammar. These techniques may operate by looking back at states associated with previously-received tokens to determine pair matching status, when a synchronizing symbol is received. The techniques can respond to the pair matching status determination by potentially adding a synthesized token or by deleting a token that has already been received. The techniques may use a structure referred to herein as a tuple to assist with the evaluation of the pair matching status. Some of the techniques utilize indentation information to evaluate the pair matching status, while other techniques ignore such information. The described embodiments also include a technique for automatically generating the tuples from a set of grammar rules associated with the parser.
