Using this approach, it is possible to achieve capacity gains in a multi-element reconfigurable antenna system without modifying the data frame of a conventional wireless communication system. The capacity gain achievable with this configuration selection approach is calculated through numerical simulations using reconfigurable circular patch antennas at the receiver of a MIMO system that employs minimum mean square error receivers for channel estimation. Channel capacity and Bit Error Rate (BER) results show the improvement offered relative to a conventional antenna selection technique for reconfigurable MIMO systems. | 11-26-2015 |
20150349418 | WIDE BAND RECONFIGURABLE PLANAR ANTENNA WITH OMNIDIRECTIONAL AND DIRECTIONAL RADIATION PATTERNS - A planar reconfigurable antenna that is capable of generating omnidirectional and directional radiation patterns over a wide frequency band or over multiple frequency bands includes a substrate, one or more pairs of conductive elements on at least one side of the substrate, a common RF feed point, and respective switches that selectively connects one or all of the conductive elements to the common RF feed point. An omni-directional radiation pattern is generated when all of the conductive elements are connected to the common RF feed point, while a directional radiation pattern is generated when only a pair of conductive elements on opposite sides of the substrate are connected to the common RF feed point. In the directional radiation mode, the conductive elements that are not connected to the common RF feed point act as a reflector for other conductive elements that are connected to the common RF feed point. | 12-03-2015 |
20160000374 | SMART KNITTED FABRICS - Knitting machines are used to intermesh conductive yarns into loops resulting in knitted fabrics. The knitting machine is adapted to import different types of yarns (conductive and non-conductive) directly into the knit structure. Combining conductive yarns and knitting systems allows for integration of electrical or mechanical component designs into existing clothing fabrication processes, avoiding current limitations of attaching or gluing conductive fabrics or other components over various materials. Starting with a planar design of an antenna, RFID tag, or some other electronic structure, the layout is converted into a CAD knitting program including a grid representing stitches. The CAD specifications of the final design/product are exported to the knitting machines so that the knitting machine may make conductive fabrics in accordance with the CAD specifications. The conductive fabrics are knitted into a variety of garments that monitor the vital signs of the wearer, including the fetus of an expectant mother. | 01-07-2016 |

20110052033 | COMPOSITE IMAGES FOR MEDICAL PROCEDURES - Medical imaging often involves the collective use of information presented in multiple images of an individual, such as images generated through different imaging modalities (X-ray, CT, PET, etc.) The use of a composite of these images may involve image registration to adjust for the variable position and orientation discrepancies of the individual during imaging. However, registration may be complicated by soft tissue deformation between images, and implementations (particularly pure software implementations) of the mathematical models used in image registration may be computationally complex and may require up to several hours. Hardware architectures are presented that apply the mathematical techniques in an accelerated manner, thereby providing near-realtime image registration that may be of particular use for the short timeframe requirements of surgical environments. The composite image generated thereby may be used to target anatomic features of interest during various medical procedures, including surgical procedures. Moreover, such techniques may be applied to computationally difficult image processing techniques, such as the display of a composite image based at least in part on a PET image, which may otherwise be difficult to utilize in a time-sensitive manner such as a surgical setting. | 03-03-2011 |
