Title: Linear drive assembly and process of using same
Inventor: WOHLFAHRT MATTHIAS
IPC: B65H19/26
Filed: 2000-03-09
Abstract: Linear drive apparatus and process of using the same. The apparatus includes a movable device and a first high-speed thrust device coupled to the movable device. The first high-speed thrust device exerts an acceleration force on the movable device to move the movable device from a ready position. A movable retaining device is coupled to the movable device, so that the retaining device is adapted to hold the movable device in the ready position against the acceleration force. A release of the movable retaining device triggers immediate movement of the movable device via the acceleration force.  The process includes positioning the movable device in an idle position, holding the movable device in the idle position with the retaining device, exerting an acceleration force on the movable device while it is being held in the idle position, and releasing the movable device from the idle position by moving the retaining device. In this manner, the acceleration force moves the moving device.

Abstract: A user interface for a financial advisory system is provided. According to one aspect of the present invention, a user may interactively explore how changes in one or more input decisions such as a risk tolerance, a savings level, and a retirement age affect one or more output values such as a probability of achieving a financial goal or an indication of short-term risk. A first and second visual indication are concurrently displayed. The first visual indication includes input mechanisms, such as slider bars, for receiving the input decisions. The second visual indication includes a set of output values that are based upon the input decisions and a recommended set of financial products. After updated values for the input decisions are received via the input mechanisms, a new recommended set of financial products and a new set of output values may be determined based upon the updated values. The second visual indication may then be updated to reflect the new set of output values. According to another aspect of the present invention, a graphical input mechanism for receiving a desired level of investment risk may be calibrated. A set of available financial products, such as a set of mutual funds, and a predefined volatility, such as the volatility of the Market Portfolio are received. The settings associated with the graphical input mechanism are constrained based upon the set of available financial products. Additionally, the calibration of the units of the graphical input mechiansm may be expressed as a relationship between the volatility associated with a setting of the graphical input mechanism and the predefined volatility.

Title: A forward error correction system for packet based real-time media
Inventor: MAHLER JERRY J
IPC: H04L1/00
Filed: 1998-12-11
Abstract: A computationally simple yet powerful forward error correction code scheme for transmission of real-time media signals, such as digitized voice, video or audio, in a packet switched network, such as the Internet. According to one aspect, an encoder at the sending end derives p redundancy blocks from each group of a k payload blocks and concatenates the redundancy blocks, respectively, with payload blocks in the next group of k payload blocks. At the receiving end, a decoder may recover up to p missing packets in a group of k packets, provided with the p redundancy blocks carried by the next group of k packets.  The invention may, for instance, append to each of a series of payload packets a single forward error correction code that is defined by taking the XOR sum of a preceding specified number of payload packets. The invention thereby enables correction from the loss of multiple packets in a row, without significantly increasing the data rate or otherwise delaying transmission.

Abstract: Methods of removing a lower alkyl alcohol from a polyester mixture of polyol fatty acid polyester and lower alkyl alcohol comprise (a) contacting the polyester mixture with a stripping mixture comprising an inert stripping gas, up to about 10,000 ppm lower alkyl alcohol and up to about 2000 ppm oxygen, wherein at least a portion of the lower alkyl alcohol is transferred from the polyester mixture to the stripping mixture, thereby increasing the concentration of lower alkyl alcohol in the stripping mixture, and (b) separating the stripping mixture from the polyester mixture. The methods further comprise (c) compressing the stripping mixture to increase its pressure, (d) cooling the stripping mixture to reduce its temperature thereby condensing at least a first portion of the lower alkyl alcohol to a liquid, (e) separating condensed lower alkyl alcohol from the stripping mixture to reduce the amount of lower alkyl alcohol in the stripping mixture to a range of from about 1 ppm to about 10,000 ppm, and (f) directing the resulting stripping mixture to an expansion turbine in which the temperature and pressure of the stripping mixture are reduced. Energy resulting from the decrease in the stripping mixture temperature and pressure in the expansion turbine is used to compress the stripping mixture separated from the polyester mixture. The methods are used to remove lower alkyl alcohol from polyol fatty acid polyesters. This invention provides an energy efficient method of removing the lower alcohol from the stripping mixture.
