Patent number: 10660587Abstract: Radiation therapy systems and their components, including secondary radiation shields. At least some versions of the disclosed systems combine a radiation delivery device, a primary radiation shielding device, and a secondary shielding layer into an integrated, modular unit. This is accomplished by using a small direct beam shield capable of blocking a primary beam from a radiation delivery device. In turn, a thinner shielding layer can be used to surround the radiation delivery device and primary shielding device, enabling a single modular unit to be delivered to an installation site. In some embodiments, a bed may be disposed within the secondary shielding layer. In some embodiments, the system is configured to provide up to 4-pi (4?) steradians of radiation coverage to the bed from the radiation delivery device.Type: GrantFiled: June 17, 2019Date of Patent: May 26, 2020Assignee: The Board of Regents of the University of Texas SystemInventors: Hak Choy, Steve Jiang, Robert Timmerman, Arnold Pompos

Publication number: 20070189420Abstract: A limiter based analog demodulator includes a power amplifier receiving a base-band signal and a local clock operating at the base-band frequency. A first multiplier receives an output from the power amplifier and the local clock to provide an in phase signal. A quadrature phase shifter receives the local clock and a second multiplier receives the output from the power amplifier and an output from the phase shifter to provide a quadrature signal. Analog filters receive the in phase and quadrature signals and analog to digital converters connected to the analog filters provide digitized in phase and quadrature signals. The phase detector then receives the digitized in phase and quadrature signals.Type: ApplicationFiled: January 19, 2006Publication date: August 16, 2007Applicant: UTSTARCOM, INC.Inventors: Zhongxuan Zhang, Lixin Zhao, Steve Jiang

Publication number: 20070018876Abstract: A digital up-sampling converter (DUSC) employs a signal input provided by a digital signal process (DSP) at a first rate feeding a Square Root Raised Cosine (SRRC) filter which provides for table look up of filter coefficients for a multiple symbol span and provides a sampling output at a second rate which is a multiple M of the first rate. A digital to analog converter (DAC) receives the sampling output at the second rate for conversion to an analog signal and a low pass analog filter processes the analog signal for delivery to an RF transmitter.Type: ApplicationFiled: January 11, 2006Publication date: January 25, 2007Applicant: UTSTARCOM, INC.Inventors: Steve Jiang, Simon Xu
