Abstract: An exoskeleton designed to be worn by a user is generally configured to support and transfer the load supported by the head, the neck and/or the torso (shoulders, chest and/or back) of the user down to the ground. The exoskeleton is generally passive and comprises at least three interconnected sections: torso, hip, and leg sections. Each of the sections generally comprises of a plurality of interconnected rigid members which form the load-bearing structure of the exoskeleton. When a user wears the exoskeleton, load normally carried by the head, neck and/or torso of the user is at least partially supported and transferred to the ground by the exoskeleton, thereby reducing the load effectively supported by the user itself. The leg sections of the exoskeleton are designed to ensure that the load-bearing final location is located on the inner side of the feet, in accordance with human biomechanics.

Abstract: One or more digital audio systems, such as a digital audio workstation, and one or more digital video systems, such as a video server, are interconnected by a computer network. A communication protocol among the systems using the computer network enables the systems to play back in synchronization. The communication protocol defines several states for connections between systems. In particular, two systems may be disconnected, connected and unlinked or connected and linked. Each system transitions through defined state changes that are caused by a sequence of commands in the communication protocol, called a play start sequence, to initiate synchronized playback. The play start sequence can be initiated by any of the linked systems. The communication protocol includes a mechanism for distributing a running time clock from the digital audio system for synchronizing with the digital video system when the digital audio system and digital video system are not both synchronized by the same video reference signal.

Abstract: Methods for reducing power required for transmitting a signal from a first transceiver to a second transceiver are described. The methods comprise the steps of estimating an excess amount of power used by the first transceiver for transmitting the signal, reducing the first transceiver's power use by the excess amount of power to a reduced power level, and transmitting the signal from the first transceiver using the reduced power level. The reduced power level achieves a transmission rate of the signal within a predefined tolerance of its preferable rate.

Abstract: Combined plain old telephone system (POTS) and digital subscriber loop (DSL) line card capable of suppressing low frequency transients. The line card includes the following elements. A DSL receive path receives DSL data from a loop. A POTS receive path receives POTS data from the loop. A combined POTS and DSL transmit path transmits POTS and DSL data to the loop. An impedance generator is coupled between the POTS receive path and the combined POTS and DSL transmit path for synthesizing impedance for signals in the combined POTS and DSL transmit path. A low frequency detector selectively applies a high pass filter to an output of the impedance generator for filtering the low frequency transients. Further, a clipped signal detector and a variable pole high pass filter are provided in the POTS receive path. The clipped signal detector in the POTS receive path triggers a switch that discharges stored transient energy in the receive path.

Abstract: A system and method for reducing peak to average power ratio (PAR) in single and multi-carrier transmitters while accounting for the effect of the transmit filters without significantly affecting a requisite transmission Power Spectral Density (PSD) mask. To this end, in a multicarrier communication system, a DSL transmitter is provided that transmits a multicarrier symbol having a controlled peak-to-average power ratio (PAR) and which is a function of a plurality of information signals. The transmitter has a power reducer that reduces the PAR of the multicarrier symbol by modifying a selected information signal of a plurality of information signals, the modified signal including an information component, a peak reduction component, and a transmission channel response component.

Abstract: The invention relates to a process of decontaminating metal (especially aluminum or aluminum alloy) scrap contaminated with organic material. The problem with such methods is that undue oxidation of the metal may take place as the decontamination proceeds, leading to reduced recovery rates. The process involves heating the scrap in a fluidized bed of solid particles fluidized by a fluidizing gas to a decontaminating temperature high enough to consume the organic material but below the melting point of the metal. The heating step is carried out in the presence of a protective material which protects the aluminum or aluminum alloy against substantial oxidation while the scrap is held in the bed at the decontaminating temperature. Preferred protective materials include organic and inorganic fluorine-containing compounds, particularly AIF.sub.3. The process is particularly effective for the treatment of aluminum alloys containing magnesium, which are especially susceptible to oxidation.

Abstract: A method of recovering an aluminum-containing metal from a scrap material containing the metal and an organic contaminant, such as paper, plastics, lacquer, paint or oil. The method involves creating a fluidized bed of solid particles, maintaining a zone of the bed at a temperature in the range of the melting point of the metal to 1000.degree. C., introducing the scrap material into the fluidized zone to cause decoating of the metal within a time in the range of 1 to 40 seconds, at least partially melting the metal, and removing the metal material from the fluidized bed. In this way, decoating and at least partial melting is achieved essentially at the same time for improved efficiency. Metals of different melting point may also be separated from each other by providing a series of temperature zones in the fluidized bed (or in a series of fluidized beds) of progressively increasing temperature.
