20110075558 | RATE SHAPING TRIGGERED DISCONTINUOUS TRANSMISSION IN WIRELESS COMMUNICATIONS - A modified token bucket algorithm in a rate shaper in a wireless communication network allows for the “borrowing” of tokens, creating the possibility of a token debt, or a token bucket with a negative Token Bucket Counter (TBC) value. In this modified token bucket algorithm, an incoming packet is passed along so long as the TBC is positive, even if the packet must “borrow” some tokens, driving the TBC negative. Subsequent incoming packets are stalled until the TBC reaches a positive value. The token bucket refills at a known rate; accordingly, the duration of traffic stalling, when the TBC is negative, is known. During this time, the UE is forced into DRX mode, saving battery power by not monitoring DPCCH for traffic that has been halted. The DRX, or sleep, mode may be invoked in several ways. | 03-31-2011 |

The interpolated Fourier coefficients are generated sequentially for individual groups of grid points. Each individual group comprises grid points that have equal distance to an origin in the regular grid, e.g. grid points that are mapped onto each other by one or ore lines of symmetry in the regular grid. The group-based processing may improve processing speed and/or reduce the need for data storage. | 02-05-2015 |
20150054759 | EFFICIENT TOMOGRAPHIC PROCESSING FOR TOUCH DETERMINATION - Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, along detection lines across a rectangular touch surface with first and second spatial dimensions. A signal processor operates to transform energy values for the detection lines into Fourier coefficients arranged as data points on a regular grid defined by first and second frequency dimensions. To generate an interaction pattern for the touch surface, the signal processor operates a first 1D inverse FFT on the data points with respect to the second frequency dimension, so as to generate first values transformed into the second spatial dimension, and operates a second 1D inverse FFT on a selected subset of the first values with respect to the first frequency dimension to generate second values that represent the interaction pattern. The selected subset is defined by the data points that fall within an extent of the touch surface in the second spatial dimension, thereby reducing the total number of inverse FFT operations. | 02-26-2015 |

The signal processor implements a normalization to ensure that the interaction pattern indicates weak touches even in the presence of strong touches. The normalization involves computing a respective normalization value for each of the differences as a function of the observed value for the respective detection line; and applying the respective normalization value so as to normalize the respective difference in the optimization function. | 03-10-2016 |
