Title: Adaptive cross-polarization equalizer
Inventor: ANDERSEN STEVEN
IPC: H04L27/01
Filed: 1995-11-29
Granted: 2003-01-21
Abstract: An equalizer employed with a receiver for cancelling an interfering signal due to low cross-polarization isolation. The present equalizer provides a simple and inexpensive cross-polarization interference cancellation system. The equalizer uses an error signal generated in an adaptive baseband equalizer to determine the magnitude of an interfering signal and inputs a cancelling signal to the co-polarized channel until power in the error signal derived from the adaptive baseband equalizer is minimized. In the equalizer, the determination of the magnitude of the interfering signal is performed at baseband (after demodulation but prior to data detection) and the cancellation is performed at RF, prior to dispersive microwave elements. The equalizer enhances the capability for transmitting two unique signals in the same frequency allocation on orthogonal polarizations. The equalizer operates even if the modulations and data rates on the two channels are different. In the receiver, co- and cross-polarized signals are received and amplified. A copy of the cross channel input signal is supplied to each receiver channel. An RF vector modulator is used to control the phase and amplitude of the cross-polarized signal prior to summation with a desired co-polarized signal. When the amplitude and the phase of the vector modulator are correctly set the interfering signal is cancelled. Control for the vector modulator is generated by minimizing the magnitude of the error signal in the adaptive baseband equalizer. The error signal is the difference between the received baseband data and an estimate of the ideal transmitted data. A control logic circuit sets the phase and amplitude for the vector modulator to minimize the magnitude of the error signal by stepping the setting of the vectormodulator by one unit and sampling the power in the error signal. If the power is reduced the vector modulator is stepped again in the same direction. If the power is increased the vector modulator is stepped in the opposite direction.

Abstract: In an engine starter comprising a pinion slidably fitted on the output shaft for driving a ring gear of an engine that is to be started, and a one-way clutch having a first end secured to the pinion and a second end which is engaged by the output shaft via spline means, a compression coil spring is interposed between a stopper secured to the output shaft and an annular shoulder defined in a cylindrical extension of the second end of the one-way clutch. Therefore, even when the pinion is forced into a high speed rotation by the engine which has been started by the engine starter, the pinion simply rotates freely, and no friction is applied to the compression coil spring or the stopper. Also, by receiving the compression coil spring in an annular space defined between the cylindrical extension of the second end of the one-way clutch and the output shaft, the compression coil spring can be protected from the centrifugal force which acts upon the compression coil spring when the output shaft of the engine starter rotates at an extremely high speed.

Abstract: A user at a remote computer is provided access to a computer network by a remote access device coupled to the network. The remote access device receives from the remote computer a username which uniquely identifies the user on the network. The remote access device then obtains an Internet protocol (IP) address from a server on the network, which server dynamically assigns the IP address based on the username. The IP address uniquely identifies the remote computer on the network, and it is needed by the remote computer to communicate on the network. If the user at the remote computer disconnects, or is disconnected, from the network and then subsequently attempts to re-gain access to the network by sending the same username to either the same or a different remote access device coupled to the network, that remote access device obtains the same IP address from the server. The user at the remote computer thus is provided with the same IP address by the server on the network when the user disconnects and then later reconnects to the network even if each of the two connections is via a different remote access device.

Title: Solvent deasphalting unit capable of generating power
Inventor: HOOD RICHARD L
IPC: C10G21/00
Filed: 1997-12-08
Granted: 2004-12-07
Abstract: Solvent deasphalting apparatus includes a separator that receives two inputs, a heavy hydrocarbon feed and a solvent feed; and the apparatus produces two outputs, an asphaltene/solvent stream and a deasphalted oil/solvent stream. A solvent recovery unit of the apparatus receives the two output streams and produces mainly a substantially solvent-free deasphalted oil product stream, a substantially solvent-free asphaltene product stream, and a recovered solvent stream which is returned to a solvent drum. A pump pumps a substantially constant volume of solvent from the solvent drum into a by-pass line connecting the pump to the solvent drum, and into a connection line connecting the pump to the separator. The amount of solvent flow in the connection line is functionally related to the level of heavy hydrocarbon feed so that solvent in excess of that flowing into the connection line and spills back to the solvent drum through the by-pass line. Finally, a power generator generates power in response to the flow of solvent in the by-pass line. The power generator includes a vaporizer for vaporizing solvent in the by-pass line, an organic vapor turbine responsive to vaporized solvent for expanding the vaporized solvent and producing expanded vaporized solvent, and generating power, a condenser for condensing the expanded vaporized solvent and producing condensed solvent, and a pump for returning the condensed solvent to the drum.
