摘要： A continuous comfort noise is provided that is overlaid for the entire duration of a conference call scenario. The comfort noise may be adapted to match the levels of the actual background noise detected on one or more of the conference call participant's devices on the transmitting end(s) of a conference call as well as the participants' speech levels. The comfort noise may also be adapted to the type of listening device employed on the receiving end of a conference call. The comfort noise level may be customized to an appropriate and comfortable level for the type of listening device being used, and the system may continuously mix the comfort noise with incoming audio signals for the entire duration of a conference call, lowering the comfort noise level gradually during speaking periods for additional user experience improvement.
摘要翻译：提供连续的舒适噪声，其在电话会议场景的整个持续时间内被覆盖。舒适噪声可以适于匹配在电话会议的发送端上的一个或多个电话会议参与者设备上检测到的实际背景噪声的电平以及参与者的语音电平。舒适噪声也可以适应于在电话会议的接收端采用的听音装置的类型。可以将舒适噪声水平定制为适用于所使用的听音装置类型的舒适水平，并且系统可以在电话会议的整个持续时间内将舒适噪声与输入音频信号连续混合，逐渐降低舒适噪声电平在演讲期间，为了增加用户体验。

摘要： The detection of double-talk in audio communication is provided. A communication device may receive an echo signal mixed with a speech signal at a near end location. The echo signal may be generated by speech transmitted by a remote party at a far end location to a local party at the near end location. The speech signal may be received from the local party for transmission to the remote party. The communication device may then filter the echo signal and the speech signal. The communication device may then analyze the speech signal to identify speech characteristics which indicate the presence of double-talk. The communication device may then set a flag upon identifying the speech characteristics which indicate the presence of the double-talk. The communication device may then process the filtered signals to further suppress remaining echo prior to transmission of the speech signal to the remote party.
摘要翻译：提供了音频通信中的双向通话检测。通信设备可以在近端位置处接收与语音信号混合的回波信号。回波信号可以由在远端位置的远程方发送的语音产生，在近端位置处的本地方。可以从本地方接收语音信号以便传送到远程方。然后，通信设备可以对回波信号和语音信号进行滤波。然后，通信设备可以分析语音信号以识别表示双方的存在的语音特征。然后，通信设备可以在识别指示双方通话的存在的语音特征时设置标志。然后，通信设备可以处理经滤波的信号，以在将语音信号发送到远程方之前进一步抑制剩余回声。

摘要： A screw and bolt clamp drive has an extension tube with a pair of block jaws adapted to hold different kinds of bolts and screws with a linked chain or metal strap. The screw and bolt clamp drive is used to drive the bolt or screw into a high ceiling beam without a ladder or lift. After the screw has been driven into the ceiling beam, the user pulls down on the extension tube thereby causing the block jaws to slide off the base frame to release the screw and chain. In an alternative embodiment, the block jaws may be replaced with a socket adapt or a screw drive tip. The clamp jaws are made to fit the base frame to clamp a bolt for fastening a metal strap to the ceiling beam.
摘要翻译：螺杆和螺栓夹具驱动器具有延伸管，其具有适于用链接的链条或金属带保持不同种类的螺栓和螺钉的一对块爪。螺钉和螺栓夹紧驱动器用于将螺栓或螺钉驱动到高天花板梁上，无需梯子或电梯。在螺钉被驱动到天花板梁中之后，使用者在延伸管上拉下来，从而使块爪从基座上滑落以释放螺丝和链条。在替代实施例中，可以用插座适配器或螺丝刀尖端代替块爪。夹钳被制成以与基座相配合以夹紧用于将金属带紧固到天花板梁上的螺栓。

摘要： A combination bicycle and boat has a frame; a buoyant rear wheel; and a buoyant front wheel driven by a pair of pedals. The frame is a rigid construction that supports the user on the front and rear wheels for mobility. The frame has a seat and rotatably mounted handle bars, and is preferably shaped to resemble an animal having a head and a tail. The combination preferably further includes a water gun powered by a water pump; and the water gun works in conjunction with a water sensing fan to facilitate a game of water tag. The invention further includes a manually propelled animal boat. The animal boat has a frame having an animal shape having a head and a tail. The animal boat has a crank is located near the head operably engages with a propeller shaped like an animal flipper located near the tail.
