Abstract: An enhanced low-bit rate parametric voice coder that groups a number of frames from an underlying frame-based vocoder, such as MELP, into a superframe structure. Parameters are extracted from the group of underlying frames and quantized into the superframe which allows the bit rate of the underlying coding to be reduced without increasing the distortion. The speech data coded in the superframe structure can then be directly synthesized to speech or may be transcoded to a format so that an underlying frame-based vocoder performs the synthesis. The superframe structure includes additional error detection and correction data to reduce the distortion caused by the communication of bit errors.

Abstract: A wood sawing machine includes a motor base, a transmission motor and a sawing device that are integrated together and disposed on the motor base, a transmission gear set and a screw rod connected to the gear set. The rotated screw rod moves a collet in a sliding sleeve such that the sawing blade assembly can be moved vertically. Thus, the machine has a simple structure and the sawing blade assembly can be lifted and lowered quickly. Due to the vertical movement, the size of the sawing machine can be reduced, and the manufacturing cost thereof can be decreased.

Abstract: Techniques and tools related to coding and decoding of audio information are described. For example, redundant coded information for decoding a current frame includes signal history information associated with only a portion of a previous frame. As another example, redundant coded information for decoding a coded unit includes parameters for a codebook stage to be used in decoding the current coded unit only if the previous coded unit is not available. As yet another example, coded audio units each include a field indicating whether the coded unit includes main encoded information representing a segment of an audio signal, and whether the coded unit includes redundant coded information for use in decoding main encoded information.

Abstract: A guiding and pressing device for a belt sander includes two triangular guiding blocks or sheet-like inclined guiding blocks, which are disposed at suitable positions on a front side frame of the sander and near to a circulating path of a sand belt. The two guiding blocks have opposite inclined surfaces near an edge of the sand belt to restrict the circulating path of the sand belt without damaging the edge of the sand belt. In addition, an elastic pressing or push rod is disposed inside the sand belt and on a backside of the frame in order to frequently push the sand belt outwards and thus to keep the sand belt in a tightened state when the belt sander is sanding.

Abstract: The invention relates to a topical composition for application to the lips comprising a reaction product of a silica dioxide, or a derivative thereof, with a dimethylsiloxy resin having a viscosity of about 1000 to about 200,000 cs, in combination with a volatile carrier.

Abstract: A method and mechanism for a client causing an electronic document to be printed without using a printer driver installed on the client is provided. A client discovers one or more printing devices on a network. The client communicates with a discovered printing device to identify the printing features supported by the discovered printing device. When the client receives a request to print an electronic document to a selected printing device, the client sends the electronic document and print configuration data to the selected printing device. As the client has been informed of the printing features supported by the selected printing device, the client can send the electronic document and the print configuration data to the selected printing device in a form readable by the selected printing device. The selected printing device processes the electronic document and the print configuration data to produce a printed copy of the electronic document.

Abstract: Techniques and tools related to delayed or lost coded audio information are described. For example, a concealment technique for one or more missing frames is selected based on one or more factors that include a classification of each of one or more available frames near the one or more missing frames. As another example, information from a concealment signal is used to produce substitute information that is relied on in decoding a subsequent frame. As yet another example, a data structure having nodes corresponding to received packet delays is used to determine a desired decoder packet delay value.

Abstract: Techniques and tools are described for processing reconstructed audio signals. For example, a reconstructed audio signal is filtered in the time domain using filter coefficients that are calculated, at least in part, in the frequency domain. As another example, producing a set of filter coefficients for filtering a reconstructed audio signal includes clipping one or more peaks of a set of coefficient values. As yet another example, for a sub-band codec, in a frequency region near an intersection between two sub-bands, a reconstructed composite signal is enhanced.

Abstract: A transfer-resistant, single phase aqueous cosmetic composition is provided. The composition contains a water-soluble, film-forming acrylic acid- or methacrylic acid-containing acrylates copolymer and a water-soluble ester. The composition is water- and oil-resistant upon drying on the skin, and exhibits high gloss and long-wearing and transfer-resistant properties. Compositions containing pigment also demonstrate high color intensity. The compositions are useful as eyeliner, mascara, lipgloss, lipliner, and other cosmetic products.

Abstract: A belt sander includes a base, a sanding device, a worktable, a tipping drive device, and a swinging device. The swinging device includes a cylindrical roller, a central shaft, a toothed ring, a drive gear, a cam, and a fixing rod. The swinging device drives the sanding device to produce a slightly reciprocally swinging action during operation of the sanding device. Thus, the grinding path and area of the sand belt are increased largely by the reciprocally and successively swinging action of the swinging device and the sanding device, so that the sand belt can be used to grind the wooden material exactly and efficiently, thereby greatly enhancing the grinding and finishing effect of the belt sander.

Abstract: The invention relates to a high gloss, non-feathering topical composition comprising at least one water-insoluble, fatty alcohol-soluble polysaccharide polymer and a liquid polymeric polyol ester.

Abstract: A gain-constrained noise suppression for speech more precisely estimates noise, including during speech, to reduce musical noise artifacts introduced from noise suppression. The noise suppression operates by applying a spectral gain G(m, k) to each short-time spectrum value S(m, k) of a speech signal, where m is the frame number and k is the spectrum index. The spectrum values are grouped into frequency bins, and a noise characteristic estimated for each bin classified as a “noise bin.” An energy parameter is smoothed in both the time domain and the frequency domain to improve noise estimation per bin. The gain factors G(m, k) are calculated based on the current signal spectrum and the noise estimation, then smoothed before being applied to the signal spectral values S(m, k).

Abstract: Various strategies for rate/quality control and loss resiliency in an audio codec are described. The various strategies can be used in combination or independently. For example, a real-time speech codec uses intra frame coding/decoding, adaptive multi-mode forward error correction [“FEC”], and rate/quality control techniques. Intra frames help a decoder recover quickly from packet losses, while compression efficiency is still emphasized with predicted frames. Various strategies for inserting intra frames and signaling intra/predicted frames are described. With the adaptive multi-mode FEC, an encoder adaptively selects between multiple modes to efficiently and quickly provide a level of FEC that takes into account the bandwidth currently available for FEC. The FEC information itself may be predictively encoded and decoded relative to primary encoded information. Various rate/quality and FEC control strategies allow additional adaptation to available bandwidth and network conditions.
