20090189675 | HIGH PERFORMANCE PSEUDO DYNAMIC PULSE CONTROLLABLE MULTIPLEXER - A high performance, set associative, cache memory tag multiplexer provides wide output pulse width without impacting hold time by separating the evaluation and restore paths and using a wider clock in the restore path than in the evaluation path. A clock controls the evaluation of the input signals. Its leading edge (i.e., rising edge) turns on NR to allow evaluation, its trailing edge (falling edge) turns off NR to stop evaluation. At this point, when NR is shut off, the inputs can start changing to set up for the next cycle. Hence the hold time of the input is determined by the clock trailing edge. | 07-30-2009 |

20090252146 | CONTINUOUS NETWORK CODING IN WIRELESS RELAY NETWORKS - Described is continuous network coding, in which a relay sends probability data comprising a continuous number for use as parity data. The node receives streams of bits sent from sources towards a destination, and computes the probability data based on current noise data and/or fading data. A selected set of the bits (all or some subset thereof) are combined, e.g., XOR-ed or concatenated, and send to the destination. Phase modulation is performed to convey probability information based on the probability data. The destination demodulates the signal to obtain the probability information, and combines the probability information with the data directly received from sources to perform joint decoding. The number of bits in the set of selected bits may be adaptively chosen based on current channel conditions, e.g., increased when the channel conditions from the sources directly to a destination are poor relative to the channel conditions via the relay. | 10-08-2009 |

20090044417 | Omni-directional Lens in Sundials and Solar Compasses - To date, the existing sundials and solar compasses use a gnomon, such as a stylet, to project a shadow under the sun on a marked surface to find the time or the true north. Because of the fussiness of the shadow and the dependence of the position of the sun with the day of the year (equation of time), the accuracy is low. The present invention discloses an omni-directional lens, which can focus the sun beam into a sharp spot with a long depth of field. By projecting the spot on a cylindrical panel, both the day of the year and the time of the day can be read off simultaneously with very high accuracy. Because of the simultaneous displaying of time and date, no equation-of-time correction is required. If the time is known, the true north can be determined with high accuracy, and the device becomes a reliable and easy-to-use solar compass. | 02-19-2009 |
20090044418 | Automatic Solar Compass - The most accurate method of finding the true north is through astronomical observations, for example, by observing the position of the sun. However, the procedure is complicated. The instantaneous position of the sun must be calculated from astronomical data for each instance of observation, and the operator must wait for the predetermined time to come. Elaborate manual adjustments are required. The present invention discloses an automatic solar compass comprising a cylindrical omni-directional lens, a detection means, and a servomechanism. It is as easy to use as the magnetic compass, but much more accurate and reliable than the magnetic compass. | 02-19-2009 |

As water in the evacuated tubes is heated by solar radiation, a hydrodynamic head is created which forces the hot water in the evacuated tubes to flow automatically into the hot water compartment(s) of the heat separator(s) and subsequently through an insulated pipe to a water tank without requiring a pump. The cool water in the water tank flows automatically through an insulated pipe back into the cool water compartment(s) of the heat separator(s) in order to preserve flow continuity. | 05-31-2012 |

To generate prosody for an input text, stress level and context information of each syllable in the text is identified. The prosody is generated by using the said correlation database to find the best set of pitch parameters for each syllable. By adding to global pitch contours and using interpolation formulas, complete pitch contour for the input text is generated.

Using Fourier analysis, the speech signal in each frame is converted into a pitch-synchronous amplitude spectrum. Using Laguerre functions, the said amplitude spectrum is converted into a unit vector, referred to as the timbre vector. By using a database of correlated phonemes and timbre vectors, the most likely phoneme sequence of an input speech signal can be decoded in the acoustic stage of a speech recognition system. | 07-17-2014 |
