Title: Method and mobile station to perform the initial cell search in time slotted systems
Inventor: BADA ANNA MARINA
IPC: H04B1/7083
Filed: 2002-01-21
Abstract: A method is disclosed that a Mobile Station MS performs at switch-on to search the most favorable target cell in UMTS systems like the 3GPP CDMA LCR (Low Chip Rate) option at (1.28) Mcps TDD (Time Division Duplex) mode and the equivalent TD-SCDMA (Time Division Synchronous CDMA). Signal at the MS antenna is the sum of different RF downlink frames coming from different carriers in the assigned frequency ranges. A DL synchronization timeslot and a BCCH TS0 are both transmitted with full power in the frames, the first one includes one out of (32) SYNC codes assigned on cell basis. Following a conventional approach the absence of a common downlink pilot and without prior knowledge of the used frequencies would force the MS, for all the frequencies of the channel raster stored in the SIM card, the correlation of the received frame with all the (32) sYNCs stored in the MS, in order to detect the BSIC of a cell to which associate the power measures. Following the two-step method of the invention the power measures are performed in towo-step scan of the PLMN  band without interleaved correlation steps; once a final frequency is selected the respective frame is the only correlated one. At least one frame duration about (5) ms long of the whole (15) MHz bandwidth is acquired, IF converted, A/D converted and the digital set is stored. A rough scan is performed multiplying the digital set by a digital IF tuned in steps wide as the channel band (1.6 MHz) along the (15) MHz band, and filtering the baseband signal with a Root Raise Cosine low-pass filter. The (5) ms baseband signal is subdivided into (15) blocks of half timeslot (337.5µs) and the power of each block is measured. The power of the strongest block indicates the priority of the respective frequency. The strongest power values are put in a Spectral Table together with respective frame load indicators. The load indicators is the percentage of timeslots in a frame almost equally loaded as the strongest block. The three strongest frequencies are selected for the successive scan.  The second step search is performed like the first one but the IF steps are now (200) kHz wide and cover the only (1.6) MHz spectrum around a selected frequency. A final frequency is selected for the successive correlation step.  Then the frequency error of the MS reference oscillator is corrected with data-aided techniques and a calibration value stored for successive connections.

Title: Method and device to optimize analyte and antibody substrate binding by least energy adsorption
Inventor: LEA PETER
IPC: G01N33/543
Filed: 2004-07-20
Abstract: The present invention provides a method of making an assay device for conducting an assay to detect a concentration of an analyte protein in a sample fluid. The assay devices would typically have a substantially planar surface having a plurality of calibration spots containing pre-determined quantities of the analyte protein printed thereon. In addition, a test dot including a capture antibody for binding the analyte protein is printed on the assay device. The method involves first modifying the planar surface to provide hydrophobic binding sites and hydrophilic linking sites.  Then the method requires printing the test spots and the calibration dots on the substantially planar surface. Applying the sample fluid to the assay device is the next step followed by testing a sensitivity of the assay and altering a ratio of the hydrophobic binding sites to the hydrophilic linking sites in order to optimize the sensitivity of the assay.

Title: Systems and methods for modifying an ice-to-object interface
Inventor: PETRENKO VICTOR
IPC: F25C5/08
Filed: 2003-02-10
Abstract: Systems and methods for thermally modifying an ice-to-object interface. One system includes a power supply configured to generate a magnitude of power.  The magnitude of the power is sufficient to melt an interfacial layer of ice at the interface; typically the interfacial layer has a thickness in a range one micron to one millimeter. A controller may be used to limit the duration in which power supply generates the magnitude of the power, to limit unneeded heat energy dissipation into the environment. Modulating the pulsed heating energy to the interface modifies a coefficient of friction between the object and the ice.

Inventor: PATEL SURESHCHANDRA B
IPC: H02J13/00
Filed: 2004-10-01
Abstract: Load-Flow computations are performed as a step in real-time operation/control and in on-line/off-line studies of Electrical Power Systems. Methods in this application are the best versions of many simple variants with almost similar performance. Simple variants include any possible hybrid combination of these methods. All of the methods are characterized: 1) In the use of a method of decomposing a network referred to as Suresh's diakoptics. Suresh's diakoptics involves determining a subnetwork for each node involving directly connected nodes referred to as level-1 nodes and their directly connected nodes referred to as level-2 nodes and so on. The level of outward connectivity for local solution of a subnetwork around a given node is to be determined experimentally. This is particularly true for matrix based methods such as Newton-Raphson(NR), BGGB, FSDL and SSDL methods. Subneworks can be solved by any of the known methods including Gauss and Gauss-Seidel methods. In the case of Gauss and Gauss-Seidel methods only one level of outward connectivity around each node is found to be sufficient for the formation of subnetworks equal to the number of nodes. Sometimes it is possible that a subnetwork around a node could be a part of the subnetwork around another node making it redundant requiring local solution of less than (m+k) subnetworks.  The local solution of equations of each subnetwork could be iterated for experimentally determined two or more iterations. However, maximum of three iterations were fond to be sufficient. 2) Sequential solution of subnetworks involves updating solution estimate of a subnetwork for immediate use in the solution of the next and subsequent subnetworks. This is referred to as block Gauss-Seidel approach. (steps-6 and -in Sequential Algorithm) 3) Parallel solution involves solution of all subnetworks using available solution estimate at the start of the iteration without intermediate updating of solution estimate. It further involves initializing a vector of dimension equal to the number of nodes with each element value zero, adding solution estimates for a node resulting from different subnetworks in a corresponding vector element, counting the number of additions and storing the average element values as initial available estimate for the next iteration.. This is referred to as block Gauss approach. Because a node could be directly connected to two or more nodes or a part of two or more subnetworks emanating from different nodes, a parallel solution iteration involves adding and taking the average of all the solution estimates or corrections obtained for a node in the parallel solution of subnetworks emanating from different nodes (steps-2 and -11 in parallel algorithm). 4) The parallel solution algorithm affords an opportunity to have simplified parallel computer a server procesor-arrey processors architecture, where each of the array processors communicate only with server processor and commonly shared memory locations and not among themselves.(Fig.6)
