摘要： A method of self-discovery and self-calibration is provided for allowing arbitrary placement of audio and video components in a multimedia conferencing system. In particular, one or more markers are provided on the audio components (e.g. microphone arrays, etc.) that are detectable by the video components (e.g. cameras). A unique signature (e.g. flashing sequence, color, etc.) characterizes each marker so that its exact location relative to the camera may be calculated. A self-calibration operation is then performed to relate, regulate and standardize dimensions and locations in the conferencing environment to the video system.

摘要： A multi-frequency tone detector with analysis window (i.e. filter size) chosen such that spectral nulls are located at adjacent frequencies of interest. The decision logic block of the tone detector uses the roll-off characteristics of the filter in conjunction with background noise to determine a threshold pass/fail for any tone that has deviated excessively from its nominal value. The foregoing aspects of the invention result in simple filter design (i.e. reduced order) relative to prior art tone detectors.

摘要： A method for detecting echo path changes in an echo canceller using the statistics of the echo canceling behavior (i.e. signal and performance information), to distinguish between new line and double talk conditions. A moving counter is incremented or decremented based on monitored levels of ERL (Echo Return Loss), ERLE (Echo Return Loss Enhancement), noise and signal energies. When the counter reaches a predetermined threshold value indicative of sustained poor echo cancellation performance, a determination is made that there is a probable new line condition (i.e. echo path change). This echo path change information is then passed to the echo canceller to enable re-convergence.
摘要翻译：使用回波消除行为（即信号和性能信息）的统计来检测回波消除器中的回波路径变化的方法，以区分新的线路和双向通话条件。基于ERL（回波回波损耗），ERLE（回波回波损耗增强），噪声和信号能量的监测电平，移动计数器递增或递减。当计数器达到指示持续较差的回波消除性能的预定阈值时，确定存在可能的新线路条件（即回波路径改变）。然后将该回波路径改变信息传递给回波消除器以实现再收敛。

摘要： A shutter for use as an objective for improving the depth of focus in a camera is disclosed. The shutter has, in a central area, a radially uniform transmission function averaged over the circumferential angle. The radial transmission function first drops off toward zero in a radial transition area which is a continuation of the central area and which has a quantity n of cutouts which extend toward the radial outside and are spaced apart from one another at equal angles 360°/n in the circumferential direction. The quantity n of cutouts has the value 5, 6 or 7.

摘要： The specific density of the liquid/air mixture is measured at successive levels within the reception vessel for the liquid using a reference measurement (Io) representing the specific density of the degasified liquid within a reference measuring path. The ratio of each obtained density value measurement and the reference value is calculated for each measuring level and multiplied with the specific density of the liquid to allow an accurate measurment of the overall liquid volume or flow-rate. Preferably the reception vessel (1) has a respective measuring electrode (El . . . En) at each measuring level with a common counter electrode (Eo) coupled to an oscillator (4) via a constant voltage circuit (5) and a coupling capacitor (6). Each measuring electrode (El-En) is coupled via a multiplexer (7) and an active rectifier (9) to an A/D converter (10) coupled to a microprocessor (11) controlling a read-out display (12).

摘要： A continuously operating centrifuge drum for concentrating suspended solids. The solids that precipitate in a stack of disks accumulate in a solids space and are diverted into a receiving chamber through mouthpieces. The mouthpieces contain throttle bores and communicate with the periphery of the solids space. To improve the known centrifuge drum to the extent that an optimal solids concentration can be obtained at low expense with no detriment to the clarified phase, there are secondary mouthpieces that also contain throttle bores, that communicate with a radially inner zone of the solids space, and that another receiving chamber is associated with. Since the volume of solids that can be diverted through the primary mouthpieces is less than the volume of solids separated in the drum, the solids flow out of the primary mouthpieces at the maximum attainable concentration, whereas the excess solids flow out through the secondary mouthpieces.

摘要： A centering device for the manufacture of a center hole in disks, particularly metallized video disks with spiral information tracks and an information-free center, employs a measuring head for the emission of a light beam onto the disk surface. The light beam is precisely situated at a boundary between the information portion and the information-free portion of the disk during a full disk revolution (a transition criterion) and that said criterion is evaluated for the identification of the center. An electronic control circuit is provided for the control of the displacements required for the measuring head and of the disk centered in planes which are parallel relative to one another.
