摘要： A method and apparatus for the variable rate coding of a speech signal. An input speech signal is classified and an appropriate coding mode is selected based on this classification. For each classification, the coding mode that achieves the lowest bit rate with an acceptable quality of speech reproduction is selected. Low average bit rates are achieved by only employing high fidelity modes (i.e., high bit rate, broadly applicable to different types of speech) during portions of the speech where this fidelity is required for acceptable output. Lower bit rate modes are used during portions of speech where these modes produce acceptable output. Input speech signal is classified into active and inactive regions. Active regions are further classified into voiced, unvoiced, and transient regions. Various coding modes are applied to active speech, depending upon the required level of fidelity. Coding modes may be utilized according to the strengths and weaknesses of each particular mode. The apparatus dynamically switches between these modes as the properties of the speech signal vary with time. And where appropriate, regions of speech are modeled as pseudo-random noise, resulting in a significantly lower bit rate. This coding is used in a dynamic fashion whenever unvoiced speech or background noise is detected.
摘要翻译： 一种用于语音信号的可变速率编码的方法和装置。 输入语音信号被分类，并且基于该分类选择适当的编码模式。 对于每个分类，选择实现具有可接受的语音再现质量的最低比特率的编码模式。 低语音平均比特率是通过在语音的部分期间采用高保真模式（即，广泛适用于不同类型的语音的高比特率）来实现的，该可靠输出需要该保真度。 在这些模式产生可接受输出的语音部分期间使用较低比特率模式。 输入语音信号分为有源和非活动区域。 有源区域进一步分为语音，清音和瞬态区域。 取决于所需的保真级别，各种编码模式被应用于活动语音。 可以根据每个特定模式的优点和缺点来利用编码模式。 当语音信号的属性随时间变化时，该装置动态地在这些模式之间切换。 并且在适当的地方，语言区域被建模为伪随机噪声，导致显着较低的比特率。 当检测到无声语音或背景噪声时，该编码以动态方式使用。

摘要： A first remote vocoder receives analog voice and produces packetized vocoder data which is transmitted over a wireless link. A first local vocoder receives the packetized vocoder data from the wireless link. The first local vocoder converts the packetized data to a multibit PCM output. The first local vocoder also adds a detection code to one of the least significant bits (LSB) of the PCM output. The first local vocoder passes the PCM signal to the PSTN from the second end user. The first local vocoder also receives PCM input over the PSTN. The first local vocoder constantly monitors the least significant bit of the PCM input for a detection code indicating that a second local vocoder is connected at the receiving end. If the first local vocoder detects the detection code from the second local vocoder, it begins to substitute packetized data and a redundancy check for a second one of the LSB's of the outgoing PCM. The first local vocoder also begins to monitor the second one of the LSB's of the incoming PCM. If the redundancy check indicates that valid packetized data has been received, the first local vocoder stops converting the PCM output into packetized data and simply passes the packetized data on the second one of the LSB's to the first remote vocoder. If at any time the redundancy check fails and the detection code is not detected, the first local vocoder returns to converting the incoming PCM to packetized data. In this way, the tandem vocoding arrangement is avoided.

摘要： An exemplary stair nosing assembly comprises an elongated base, a plate adhered to the base, and a cover temporarily covering the base and the plate. The base has at least one anchor portion extending downwardly from the upper portion for attaching to a lip of a tread pan and/or embedding in a concrete tread. The plate can have various features to enhance traction and visibility. The cover has front and rear lips that engage with front and rear edges of the base, and a weakened region adjacent the rear lip. When the assembly is embedded in a concrete tread, the cover is configured to fracture at the weakened region when the front lip of the cover is lifted upward from the base, leaving the rear lip remaining embedded in the concrete and allowing the rest of the cover to be removed to expose upper surfaces of the base and plate.

摘要： A protective housing for a circuit board mounted on an end of a cell is described. The protective housing includes a cut-out in its sidewall and a retaining wall centered in the cut-out. This provides a pair of gaps, one on each side of the retaining wall between the cut-out. These gaps are size so that lead wires extending from the circuit board are captured therein in a tight-fitting relationship. Consequently, the lengths of the leads extending from the protective housing of the cell to a quick disconnect at the distal end of the leads is precisely controlled. If desired, there can be more than one retaining wall providing a plurality of gaps for capturing a plurality of lead wires therein.

摘要： A pneumatically actuated clip for a paintball gun may include a driving member such as a soft sealing ball or a flexible drive piston that conforms in shape and size to a cross-sectional area of a passageway containing a supply of paintballs. The passageway preferably provides a paintball route (or pathway) inside the clip that supplies the paintballs to the paintball gun. In one embodiment, the driving member creates a pneumatic chamber (sealing as it moves) in the area behind the driving member. Pressurized gas supplied to the pneumatic chamber preferably drives the driving member and the supply of paintballs forward along the pathway. The pressurized gas that drives the driving member can, for instance, be controlled by means of an integrated regulator or can be a timed pulse of air supplied through a solenoid valve as controlled by a signal from a control board. The signal could be generated using a breech sensor to determine when a paintball has been loaded into the breech to determine when to actuate the supply solenoid. Alternatively, a pressure switch can control the supply of pressurized gas through a solenoid. Other features and embodiments are also disclosed.
