    Abstract: A pitch-synchronous method and system for speech coding using timbre vectors is disclosed. On the encoder side, speech signal is segmented into pitch-synchronous frames without overlap, then converted into a pitch-synchronous amplitude spectrum using FFT. Using Laguerre functions, the amplitude spectrum is transformed into a timbre vector. Using vector quantization, each timbre vector is converted to a timbre index based on a timbre codebook. The intensity and pitch are also converted into indices respectively using scalar quantization. Those indices are transmitted as encoded speech. On the decoder side, by looking up the same codebooks, pitch, intensity and the timbre vector are recovered. Using Laguerre functions, the amplitude spectrum is recovered. Using Kramers-Kronig relations, the phase spectrum is recovered. Using FFT, the elementary waves are regenerated, and superposed to become the speech signal.

    Abstract: Sundials and solar compasses including are disclosed. Some embodiments include an omni-directional lens, which can focus a sun beam into a sharp spot with a long depth of field. By projecting the spot onto 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.

    Abstract: The present invention is a method and system to convert speech signal into a parametric representation in terms of timbre vectors, and to recover the speech signal thereof. The speech signal is first segmented into non-overlapping frames using the glottal closure instant information, each frame is converted into an amplitude spectrum using a Fourier analyzer, and then using Laguerre functions to generate a set of coefficients which constitute a timbre vector. A sequence of timbre vectors can be subject to a variety of manipulations. The new timbre vectors are converted back into voice signals by first transforming into amplitude spectra using Laguerre functions, then generating phase spectra from the amplitude spectra using Kramers-Knonig relations. A Fourier transformer converts the amplitude spectra and phase spectra into elementary waveforms, then superposed to become the output voice. The method and system can be used for voice transformation, speech synthesis, and automatic speech recognition.

    Abstract: A solar-powered cooling and heating system comprising one or more vertical water containers of special design as the thermal storage device (the structured water wall), a compressor driven by a DC motor powered directly by solar photovoltaic panel(s) for cooling, and a south-faced window for direct solar heating. The solar photovoltaic panel(s) is placed on an awning above the south-facing window; the said awning is designed to allow full sunlight in the winter but no direct sunlight in the summer through the window. The thermal inertia of the structured water wall allows optimum heating and cooling day and night for all seasons of a year. It allows an automatic self-adjustment utilizing the natural annual and diurnal cycles to achieve maximum comfort and efficiency.

    Abstract: A solar-powered refrigerator is disclosed. It uses a solar photovoltaic panel to convert solar energy to electricity to power a DC motor. The DC motor drives the compressor of a vapor-compression refrigeration system to freeze an energy-storage vessel, located in the freezer. The energy-storage vessel is filled with a mixture of glycerin, alcohol and water, with a freezing point of 10° F. to −10° F. In the absence of sunlight, the temperature of the frozen mixture can maintain near its freezing point for more than one day. The temperature of the refrigerator is maintained to a desirable value, for example 37° F., by a pair of heat-exchange coils and a thermostat, with or without sunlight.

    Abstract: 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.

    Abstract: An apparatus and a method for imaging the mouth area laterally to produce reliable measurements of mouth and lip shapes for use in assisting the speech recognition task. A video camera is arranged with a headset and a microphone to capture a lateral profile image of a speaker. The lateral profile image is then used to compute features such as lip separation, lip shape and intrusion depth parameters. The parameters are used in real time, during speech recognition process to characterize and discriminate spoken phonemes to produce a high degree of accuracy in automatic speech recognition processing, especially in a noisy environment.

    Abstract: An automatic segmenter for continuous text segments such text in a rapid, consistent and semantically accurate manner. Two statistical methods for segmentation of continuous text are used. The first method, called "forward-backward matching", is easy and fast but can produce occasional errors in long phrases. The second method, called "statistical stack search segmenter", utilizes statistical language models to generate more accurate segmentation output at an expense of two times more execution time than the "forward-backward matching" method. In some applications where speed is a major concern, "forward-backward matching" can be used, while in other applications where highly accurate output is desired, "statistical stack search segmenter" is ideal.
