    • A minimum level for a stimulation signal used in room correction processing is determined by measuring background noise. The stimulation signal is repeated a number of times and resulting responses are recorded. The recording responses are averaged, and the average is subtracted from each recorded response to obtain the backg round noise present in each recorded response. A stimulation signal to background noise ratio is computed from the stimulation signal and background noise and compared to an SNR threshold to determine if the stimulation signal level is sufficient to support the room correction processing. The background noise may be AC hum introduced electronically into the response signal, acoustic noise introduced by AC ventilation systems or noise emitting devices (refrigerators, etc), and it may be structure-born noise introduced by shaking the microphone, e.g. a bus drives by, shaking the floor the microphone is standing on.
    • 通过测量背景噪声来确定在房间校正处理中使用的刺激信号的最小水平。 刺激信号重复多次,并记录所得到的响应。 记录响应被平均,并且从每个记录的响应中减去平均值,以获得每个记录的响应中存在的反循环噪声。 从刺激信号和背景噪声计算背景噪声比的刺激信号,并与SNR阈值进行比较,以确定刺激信号电平是否足以支持房间校正处理。 背景噪声可以是电子地引入到响应信号中的AC嗡嗡声,由交流通风系统或噪声发射装置(冰箱等)引入的声学噪声,并且它可以是通过摇动麦克风引入的结构噪声噪声。 一辆公共汽车驾驶,摇晃麦克风站在地板上。

    • The present invention is a putting alignment and aiming tool, to assist a user in aligning and aiming a putt on a putting surface with a golf ball. The tool can be colored or in black and white and have a generally horizontally flat coin body with a top flat surface with a middle portion, a bottom flat surface, two linearly squared off sides, a concaved top side and a convex bottom side. The tool is placed behind the golf ball with the bottom flat surface in flat physical contact with the putting surface that indicates an intended putting line. The top flat surface is also visible to the user to assist the user in aligning and aiming the putt on the putting surface with the golf ball towards a hole or practice cup. There is also an overall method of usage for both the colored and black and white tools also.

    • A seat belt assembly for a vehicle that includes an anchor portion having an anchor bolt adapted to attach to a vehicle. A seat belt web is associated with the anchor portion. A sheath member is coupled to the anchor portion with the sheath member having opposing top and bottom surfaces and opposing side surfaces. The opposing top and bottom surfaces and opposing side surfaces define an interior cavity. The sheath member includes a plurality of detents formed on the opposing side surfaces. An extension plate having opposing proximal and distal ends as well as opposing top and bottom surfaces bounded by opposing lateral edges is slidingly disposed within the interior cavity of the sheath member. The extension plate includes a pair of arms formed on the opposing lateral edges. An extension arm formed about the extension plate includes first and second ends with the first end coupled to the proximal end of the extension plate. The second end of the extension arm includes a web guide formed on an end. The pair of arms releasably engage the plurality of detents for telescopic adjustment of the extension arm whereby the web guide is movable to a plurality of positions.

    • A traffic crossing warning device is provided. The device includes a beam transmitter for transmitting a beam such as an IR beam, and a beam sensor in electrical communication with a signal processor for sensing the IR beam. In addition, the device includes a multimedia warning beacon, and a mounting device for supporting the beacon adjacent a roadway intersection. The warning beacon is activated when the beam sensor senses that the beam is not being received for a predetermined period of time. In one aspect, the warning beacon has a warning light, a speaker for delivering an audible signal, and a display for providing a written warning. A method for warning motorists of the presence of an oncoming locomotive object such as a train using the warning device is also provided.
