Patent number: 6507745Abstract: An apparatus for controlling transmission power during the establishment of a channel in a CDMA communication system utilizes the transmission of a short code from a subscriber unit to a base station during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional spreading code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The subscriber unit quickly increases transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, it sends an indication to the subscriber unit to cease increasing transmission power. The use of short codes limits power overshoot and interference to other subscriber units and permits the base station to quickly synchronize to the spreading code used by the subscriber unit.Type: GrantFiled: March 1, 2002Date of Patent: January 14, 2003Assignee: InterDigital Technology CorporationInventors: Fatih M. Ozluturk, Gary R. Lomp

Patent number: 6507752Abstract: From ECG-gated SPECT or PET images of radioactive myocardial perfusion imaging agents, contraction of the myocardium along the tangential direction, i.e., in the direction parallel to the myocardium, can be evaluated. The amount of the agents which accumulate in the heart muscle is calculated from reconstructed short-axis ECG-gated images and is projected on a virtual cylindrical screen whose axis is the same as the long axis of the heart. Spatial and temporal changes in time and space in the projected count distribution on the screen are described by a two-dimensional second order differential equation, which is called an equation of continuity for the fluid. This equation can be solved numerically with a computer. The displacements of points on the myocardium in the tangential direction are calculated by projecting the displacement of each point back onto the cardiac wall. From these displacements, contraction and expansion of the heart muscle can be quantified.Type: GrantFiled: October 10, 2000Date of Patent: January 14, 2003Inventor: Hisatoshi Maeda
