Patent number: 8207874Abstract: An encoder employs a trellis coded quantization (TCQ) unit and a compression unit. The TCQ uses a set of polynomials that have been selected to maximize granular gain. The TCQ unit operates on a block of samples from a source. The compression unit compresses bit planes of the TCQ output, using parity check matrices of corresponding LDPC codes, to obtain corresponding syndromes. The parity check matrices are selected so their compression performance approaches close to the limit for Slepian-Wolf coding. A decoder employs a decoding unit and an estimation unit. The decoding unit decodes the syndromes using side information to produce an estimate for the TCQ output. The side information is correlated with the source. The estimation unit estimates the block of source samples using the estimated TCQ output and the side information. Trellis coded vector quantization may be used as an alternative to TCQ.Type: GrantFiled: August 4, 2008Date of Patent: June 26, 2012Assignee: The Texas A&M University SystemInventors: Yang Yang, Zixiang Xiong

Patent number: 8207992Abstract: 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.Type: GrantFiled: December 5, 2008Date of Patent: June 26, 2012Assignee: University of Maryland, BaltimoreInventors: Raj Shekhar, Omkar Dandekar

Patent number: 8207451Abstract: A ground-plane slotted type signal transmission circuit board is proposed, which is designed for use with a high-speed digital signal processing system for providing a low-loss signal transmission function. The proposed circuit board structure is characterized by the formation of a slotted structure (i.e., elongated cutaway portion) in the ground plane at the beneath of each signal line. Since the slotted structure is a void portion, the electric field of a gigahertz signal being transmitting through the overlaying signal line would be unable to induce electric currents in the void portion of the ground plane. This feature allows the prevention of a leakage current that would otherwise flow from the signal line to the ground plane, and therefore can help prevent unnecessary power loss of the transmitted signal.Type: GrantFiled: September 24, 2008Date of Patent: June 26, 2012Assignee: National Taiwan UniversityInventors: Hsin-Chia Lu, Tsung-Yi Chou

Systems, methods, and computer readable media for fractional pre-emphasis of multi-mode interconnect
Patent number: 8208578Abstract: Systems, methods, and computer readable media for fractional pre-emphasis of multi-mode interconnect are disclosed. According to one aspect, the subject matter described herein includes a method for fractional pre-emphasis of multi-mode interconnect. Multiple bits of binary data are periodically received. For each period, the multiple bits of binary data are encoded into multiple scalar values, each value representing a level of an analog signal to be output over a multi-mode interconnect system during the current period. Multiple analog signal outputs are generated corresponding to multiple scalar values, each signal output being driven to a level according to its corresponding scalar value. For each representative scalar value, a difference between the scalar value generated during the current period and the scalar value generated during the previous period is determined, and a pre-emphasis signal that is proportional to the difference is generated.Type: GrantFiled: June 21, 2010Date of Patent: June 26, 2012Assignee: North Carolina State UniversityInventors: Paul D.
