    摘要： An intermediate symbol buffer (ISB) configuration and method is provided such that the ISB memory comprises 15 portions, one for each HSDPA spreading code. Symbols associated with a spreading code are written to the memory portion associated with the same spreading code. When a covariance calculation is performed to obtain a more accurate channel estimate, only the symbols associated with spreading codes determined to be needed for the covariance calculation are written to the ISB by a buffer block and red from the ISB by a correlation core. The symbols associated with spreading codes that are not necessary for a covariance calculation may be masked from being written or read from the ISB. In some embodiments each memory portion is an individual memory block. In other embodiments a plurality of memory blocks may contain a plurality of memory portions, one memory partition designated, at least temporarily, for each spreading code.

    摘要： The present invention relates to a display device with a birefringent lens system having cylindrical lenses, extending in a main direction. The polarisation of light modulated by a LC layer is twisted by a rotator layer (25′) in order to be perpendicular or parallel with this main direction. A birefringent compensation layer (26) is used to remove any ellipticity introduced by the rotator layer (25′). This provides improved contrast when the display device is used e.g. in a switchable 2D/3D display.

    摘要： An electric field object sensing system (1) and method. The system (1) comprises a transmitter electrode (2), a receiver electrode (4), a switching circuit (32) coupled to the receiver electrode, an alternating voltage source (3) coupled to the transmitter electrode (2) and the switching circuit (32), and an output connection (34) coupled to the receiver electrode (4). Charge pumping performed according to the alternating voltage cycle provides a voltage over a capacitor (43) of the switching circuit (32) that increases dependent upon the capacitive coupling between the transmitter electrode (2) and the receiver electrode (4). The voltage over the capacitor (43) of the switching circuit (32) is allowed to saturate, and the saturated voltage is used as an output (20) that varies when an object (8) is in the vicinity of the transmitter and receiver electrodes. The output (20) may be fed to a high impedance read-out means e.g. an (24). The system (1) may be implemented in CMOS and integrated in control circuits of electronic products.

    摘要： The state transition of a linear feedback shift register (LFSR) controlled by a clock (310) with length N and step size W, W being at least two, is accomplished via a next-state function (320). The next-state function deploys a state transition matrix (350). The state vector (330), which represents the contents of the LFSR, is either multiplied sequentially by the state transition matrix or multiplied by the state transition matrix to the power of W (multiple state transition matrix). The method and the LFSR according to the invention are characterized in that the multiple state transition matrix is decomposed in a first matrix (360) and a second matrix (370), the first matrix comprising at most N+W+1 different expressions and the second matrix comprising at most N+W+1 different expressions. The LFSR further comprises means to multiply the state vector by the second matrix and the first matrix, and means for computing the first matrix. The invention overcomes the shortcomings of configurable multi-step linear feedback shift registers because the amount of time needed to generate the output can be reduced significantly.

    摘要： A combined passive and active object sensing system (30; 50; 70) employing electric field sensing is described. An electric field sensing transmission electrode (2) generates a first electric field (11, 12, 13) that induces a current in an electric field sensing reception electrode (4). A passive object (10) is sensed from variation in this current. An active object (31; 51; 71) comprises a further electric field sensing transmission electrode (33; 53; 73) and generates a second electric field (35, 36, 37; 55, 56, 57; 75, 76, 77). This may be generated by the active object (31) coupling with and applying a phase shift to the first electric field (11, 12, 13). Alternatively the second electric field (55, 56, 57) may be generated at a different frequency to the first electric field (11, 12, 13). Alternatively the second electric field (75, 76, 77) may be generated by the active object (71) coupling with an alternating magnetic field generated by a coil (172). The second electric field (35, 36, 37; 55, 56, 57; 75, 76, 77) induces a current in the electric field sensing reception electrode (4) that varies with the position of the active object (31; 51; 71). The separate currents are distinguished by virtue of their different phase or frequency.
