Appl. No.:

11/429243

Inventors:

Weidong Zhu - Elridge MD, US
Yan Chen - Baltimore MD, US

Assignee:

University of Maryland, Baltimore County - Baltimore MD

International Classification:

B66B 7/06
B66B 5/00

US Classification:

187411, 187251, 187345, 187393, 187414, 254277, 212273

Abstract:

A vibration damped elevator system is provided that includes a damper or dampers attached to the elevator cable. The damping coefficients of the damper or dampers are chosen to provide optimum dissipation of the vibratory energy in the elevator cable. A method of determining the optimum placement of the damper or dampers and their respective damping coefficients is also provided.

Appl. No.:

14/262153

Inventors:

- College Park MD, US
Yan Chen - Greenbelt MD, US
K. J. Ray Liu - Potomac MD, US

International Classification:

H04L 27/36
H04B 1/38

Abstract:

Time-reversal wireless communication includes: at a base station, receiving a probe signal from a terminal device; generating a signature waveform that is based on a time-reversed signal of a channel response signal derived from the probe signal; performing quadrature amplitude modulation (QAM) on a transmit signal to generate a quadrature amplitude modulated signal; and generating a transmission signal based on the quadrature amplitude modulated signal and the signature waveform.

H04W 56/00

Abstract:

A handshaking process for time-reversal wireless communication is provided. A first device receives a handshake signal transmitted from a second device through multiple propagation paths, the handshake signal including a preamble and a training sequence, in which the training sequence includes a sequence of symbols known to the first and second devices. A synchronization index is determined based on the preamble, and the training sequence in the handshake signal is identified based on the synchronization index. A channel response signal is determined based on the received training sequence, and a signature waveform that is a time-reversed signal of the channel response signal is generated. A transmission signal is generated based on transmit data and the signature waveform, in which the transmit data are data configured to be transmitted to the second device.
