Publication number: 20100082082Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.Type: ApplicationFiled: April 7, 2009Publication date: April 1, 2010Inventors: Mani Prakash, Francesca Rossetto, Anthony Lee, Steven Kim, Ted Su, Jonathan Glassman

Publication number: 20090217133Abstract: A high performance real-time turbo code system is proposed. The proposed system exploits cooperative coding architecture and a proper decoding scheduling to achieve low error rate within a constrained latency. Permutation schemes and hardware embodiments utilizing the cooperative coding are also shown. Various memory saving techniques are provided to reduce memory usage in both encoder and decoder. The proposed system is compatible with 3rd generation mobile standards and cost of designing new parts exclusively for the proposed system can be minimized. This invention can provide substantial coding and system capacity gains for real-time applications in a wireless environment.Type: ApplicationFiled: May 1, 2009Publication date: August 27, 2009Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE (ITRI)Inventors: Yan-Xiu Zheng, Yu-Ted Su

Publication number: 20090149850Abstract: This invention is an improved tissue-localizing device with an electrically energized locator element for fixedly yet removably marking a volume of tissue containing a suspect region for excision. The electrical energizing of the locator element facilitates the penetration of the locator element in to subjects tissue and minimizes resistance due to dense or calcified tissues. At least one locator element is deployed into tissue and assumes a predetermined curvilinear shape to define a tissue border containing a suspect tissue region along a path. Multiple locator elements may be deployed to further define the tissue volume along additional paths defining the tissue volume border that do not penetrate the volume. Delivery of electric cut-rent may be achieved through monopolar or bipolar electronic configuration depending on design needs. Various energy sources, e.g., radio frequency, microwave or ultrasound, may be implemented in this energized tissue-localizing device.Type: ApplicationFiled: December 10, 2008Publication date: June 11, 2009Inventors: Roman Turovskiy, Ted Su, Steven Kim, Mani N.

Publication number: 20080240310Abstract: A method for estimating frequency offset is provided. First, a baseband signal with a preamble featuring quasi-periodic property is received. Next, the quasi-periodic property of the preamble of the received baseband signal is reconstructed by interpolation.
