A method for compressing audio input signals to form a master bit stream that can be scaled to form a scaled bit stream having an arbitrarily prescribed data rate. A hierarchical filterbank decomposes the input signal into a multi-resolution time/frequency representation from which the encoder can efficiently extract both tonal and residual components. The components are ranked and then quantized with reference to the same masking function or different psychoacoustic criteria. The selected tonal components are suitably encoded using differential coding extended to multichannel audio. The time-sample and scale factor components that make up the residual components are encoded using joint channel coding (JCC) extended to multichannel audio. A decoder uses an inverse hierarchical filterbank to reconstruct the audio signals from the tonal and residual components in the scaled bit stream.

Methods, for use with a laser ablation or drilling process, which achieve depth-controlled removal of composite-layered work-piece material by real-time feedback of ablation plasma spectral features. The methods employ the use of electric, magnetic or combined fields in the region of the laser ablation plume to direct the ablated material. Specifically, the electric, magnetic or combined fields cause the ablated material to be widely dispersed, concentrated in a target region, or accelerated along a selected axis for optical or physical sampling, analysis and laser feedback control. The methods may be used with any laser drilling, welding or marking process and are particularly applicable to laser micro-machining. The described methods may be effectively used with ferrous and non-ferrous metals and non-metallic work-pieces. The two primary benefits of these methods are the ability to drill or ablate to a controlled depth, and to provide controlled removal of ablation debris from the ablation site. An ancillary benefit of the described methods is that they facilitate ablated materials analysis and characterization by optical and/or mass spectroscopy.

Disclosed is a method for scaling and extending the reach of UPnP device discovery and eventing by leveraging the use of a peer-to-peer network infrastructure. Peer-to-peer networking allows for the organization of a set of nodes into a group for efficient exchange of information and the group has an efficient and scalable mechanism for flooding data to all members in it. In one embodiment one PC in a peer group can receive device discovery announcements and subscribe for device event notifications. A discovery proxy and an eventing proxy running on the PC package the announcement and/or notification in a record and proceed to flood it to the group. The group flooding semantics route the notification to the subscribed controllers, which can subsequently take suitable action. Ultimately, this method produces a result whereby device discovery and eventing tasks can be fulfilled by locating the closest peer and obtaining the device announcements and notifications from that peer.

A digitally implemented slew rate controller for a power supply and a power supply having the same. An output up-programming signal is provided that enables the power supply to change an output voltage and current at a maximum rate which does not engage the protection circuits which are employed to protect components of the power supply. The maximum rate of change decreases as the output voltage increases. The up-programming speed of the power supply output optimizes the output by considering that an amount of output current available for charging an output capacitor of the power supply will decrease as the output voltage increases for a resistive load. An output down-programming control signal enables a discharge device to dissipate heat with a constant power characteristic, which will minimize a time required to reduce the output voltage while not exceeding a maximum power dissipation rating of the discharge device.
