Abstract: The system for inspecting an object comprises a structure having a first, second and third orthogonal axes, and a source of x-ray pencil beam mounted thereto along the first axis. An incident radiation detector is mounted to the structure perpendicularly to the first axis. A first and second linear arrays of scattered radiation detectors are mounted to the structure perpendicularly to the second and third axes respectively. The source of x-ray pencil beam, the incident radiation detector and the first and second linear arrays of scattered radiation detectors are spaced apart and define therebetween an inspection zone. In use, an object to be inspected is moved inside the inspection zone relative to the x-ray pencil beam. The object is inspected voxel by voxel and the radiation measurements taken at each voxel are indicative of incident radiation attenuation, scattered radiation attenuation and electron density of that voxel.

Abstract: An adaptable orthogonal frequency-division multiplexing system (OFDM) that uses a multiple input multiple output (MIMO) to having OFDM signals transmitted either in accordance with time diversity to reducing signal fading or in accordance with spatial diversity to increase the data rate. Sub-carriers are classified for spatial diversity transmission or for time diversity transmission based on the result of a comparison between threshold values and at least one of three criteria. The criteria includes a calculation of a smallest eigen value of a frequency channel response matrix and a smallest element of a diagonal of the matrix and a ratio of the largest and smallest eigen values of the matrix.

Title: Real-time monitoring of photodynamic therapy over an extended time
Inventor: CHEN JAMES C
IPC: A61K41/00
Filed: 2000-05-26
Granted: 2007-10-30
Abstract: Progress of photodynamic therapy (PDT) administered over an extended period of time is monitored using an ultrasonic probe (30), which produces ultrasound images of an internal treatment site in real time. The ultrasound images indicate the extent and volume of an infraction zone within a tumor (20) or other diseased tissue at the internal treatment site within a patient's body. Light is administered to the internal treatment site from either an internal or external light source that produces light in a waveband corresponding to the characteristic absorption waveband a photoreactive agent that is administered to a patient. Prior to or shortly after initiating administration of the light therapy, a baseline ultrasound image is produced for comparison to subsequent ultrasound images made after the effects of the PDT on the diseased tissue have occurred.

Abstract: A system and method for enhancing acoustic signal buried in noise. The invention matches the acoustic input to a signal model and produces a corresponding output that has very low noise. Input data are digitized, transformed to a time-frequency representation, background noise is esti-mated, and transient sounds are isolated. A signal detector is applied to the transient. Long transients without signal con-tent, and the background between the transients, are included in the noise estimate. If at least some part of a transient contains signal of interest, the spectrum of the signal is compared to the signal model after rescaling, and the signal's parameters are fitted to the data. Low-noise signal is resynthesized using the best fitting set of signal model parameters. Since the signal model only incorporates low noise signal, the output signal also has low noise. Before the enhancement can occur, the signal model is trained with low-noise signal data. The model is built by creating templates from the spectrograms when they are significantly different from existing templates.  If an existing template is found that resembles the input pattern, the template is averaged with the pattern in such a way that the resulting template is the average of all the spectra that matched that template in the past.

Abstract: The object is to control interference in a permissible range by applying the CDMA system to signal collision in the conventional CSMA and TDMA base multihop systems and to relax the hidden terminal problem and others to enhance the throughput of the entire system by grouping of channel groups in multihop transmission and by control of transmission based on an interference level from another station. A multihop relay station calculate a desired signal level, for example, from an interference level at its own station of a packet sent from a mobile station, and notifies the mobile station of the desired signal level; and the mobile station calculates a transmission power amount of a packet from the desired signal level, determines whether the packet is transmissible to the station as a source of the desired signal level, on the basis of the transmission power amount, and transmits the packet by a power of the transmission power amount to the source station determined as a packet-transmissible station. On this occasion, an interference signal is weakened by assignment of channel groups 1,2 for transmission of signals.
