Abstract: A composite film suitable as a donor support in a radiation-induced thermal transfer imaging process, said film comprising a polymeric substrate and a transfer-assist coating layer derived from an aqueous composition comprising one or more water-soluble or water-dispersible radiation-absorbing compound(s).

Abstract: A donor element useful in an assemblage for imaging by exposure to light comprises a support layer formed by a stretching process, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The light-to-heat conversion layer is coated on the support prior to completion of the stretching process.

Abstract: A method and apparatus for detecting a singing frequency in a signal processing system using two neural-networks is disclosed. The first one (a hit neural network) monitors the maximum spectral peak FFT bin as it changes with time. The second one (change neural network) monitors the monotonic increasing behavior. The inputs to the neural-networks are the maximum spectral magnitude bin and its rate of change in time. The output is an indication whether howling is likely to occur and the corresponding singing frequency. Once the singing frequency is identified, it can be suppressed using any one of many available techniques such as notch filters. Several improvements of the base method or apparatus are also disclosed, where additional neural networks are used to detect more than one singing frequency.

Abstract: A computer program of the type commonly known as a “wizard” is disclosed that initializes user interface software for controlling an audio conferencing device. The wizard allows the desired audio inputs (e.g., microphone, telephones, etc.) and audio outputs (speakers, recording devices, etc.) to be chosen by an audio system administrator. Thereafter, the wizard allows an audio conferencing device (or devices) to be chosen by the administrator, or allows such a device(s) to be optimally chosen dependent upon the chosen inputs and outputs. The wizard then maps the inputs and outputs to the input and output ports on the audio conferencing device, a step which again can be performed manually by the administrator or automatically by the wizard. After reviewing the mapping results, the administrator finishes the wizard, which computes the mapping parameters and other audio-optimizing parameters for the selected inputs and outputs.

Abstract: The invention relates to an indexable drill for drilling a hole in a metal workpiece. The drill includes an elongated generally cylindrical body having a central longitudinal axis and a pair of cutting inserts. The body includes a tip end portion having first and second recessed pockets on generally diametrically opposite sides of the longitudinal axis. Each cutting insert is removably secured within a pocket and includes at least one cutting edge having an outer peripheral corner and an inner corner. The at least one cutting edge extends linearly from the outer peripheral corner to a curve extending convexly toward an inner region proximate the central longitudinal axis and then to a linear relief edge extending linearly from the inner region in a direction away from the longitudinal axis to the inner corner.
