摘要： A conferencing device is described which includes at least one speaker, at least one microphone for capturing energy corresponding to near-end speech, a signal interface for connecting to a voice communication system, and a digital signal processor. The digital signal processor is operable to process near-end signals corresponding to the near-end speech energy in each of a plurality of frequency bands to improve intelligibility thereof, and transmit the processed near-end signals to the voice communication system via the signal interface. The digital signal processor is also operable to receive far-end signals from the voice communication system via the signal interface, process the far-end signals in each of the plurality of frequency bands, and transmit the processed far-end signals for presentation over the speaker.

摘要： Methods and apparatus are described for use with a near-end telephone. The near-end telephone is operable to generate an outgoing signal directed to a far-end telephone and to receive an incoming signal generated at least in part by the far-end telephone. A first signal processor is operable to dynamically adjust a first signal level associated with the outgoing signal with reference to the first signal level. A second signal processor is operable to dynamically adjust a second signal level associated with the incoming signal with reference to the second signal level. The first and second signal processors are further operable to control a loop gain to inhibit loop instability.

摘要： A conferencing system is described which includes a plurality of conferencing devices and a hub device. Each conferencing device is operable to process near-end speech energy signals to improve the intelligibility of the near-end speech, transmit the processed near-end signals to the hub device, receive far-end signals from the hub device, process the far-end signals, and present the processed far-end signals over its speaker. The hub device is operable to communicate with each of the conferencing devices and a voice communication system, selectively combine the processed near-end signals received from the conferencing devices, transmit the combined near-end signals to the voice communication system, receive the far-end signals from the voice communication system, and transmit the far-end signals to the conferencing devices.

摘要： An automated vehicle protection system is provided comprising a guideway (20), a vehicle (10), a guideway loop antenna (21), and transponders (41a, 41b), mounted on the vehicle (10). Means (24, 25) are provided, couple to the guideway loop antenna (21), for receiving a signal from the vehicle (10) and generating an inhibit signal in order to inhibit vehicle movement in a section of the guideway (20). The inhibit signal may be passed to a circuit associated with another guideway loop antenna (22, 23) to control transmission of a signal from this other guideway loop antenna (22, 23).

摘要： A welding tool has a handle with a base end and an exit end. A bottom plate is affixed to the base end and preferably encloses the base end of the handle. A washer is affixed to the exit end of the handle. The washer defines an orifice and provides a surface for preventing a user's hand from slipping during use of the welding tool. A plurality of rods extends outwardly from the handle through the orifice. The rods are preferably affixed to the bottom plate at a base end and have a surface contacting end. The rods are sized to permit limited flexure, but to still be substantially rigid to effectively remove slag from a weld.
