Abstract: Touch sensor panels (104) have 2-D periodic arrangements of electrodes (304) connected together forming a plurality of horizontal and vertical logical lines (506, 514) for measuring X-Y coordinates of a user's touch. Electrodes forming the horizontal logical lines are interleaved with electrodes forming the vertical logical lines. Each of the vertical and horizontal logical lines includes multiple tracks (502, 504, 510, 512). The tracks of each logical line are cross connected by in-plane cross connects (314, 318) formed in the same layer by the same process that is used to form the electrodes. Diamond and square electrode embodiments are described.

Abstract: A rechargeable touch sensor equipped device (102) is adapted to identify (1008) each of multiple external charging devices (118, 120, 122, 602) by an ID or other information received through an interface (230, 630) or to infer the identity (1020) based on location information derived from received wireless signals, the time and/or day. The rechargeable touch sensor equipped device (102) determines (1026) and records (1028) a touch screen operating frequency to be used when coupled to each external charging device (118, 120, 122, 602) at each battery charge state (or other indication of power draw) and in this way mitigates the adverse effect of variable charger generated noise on the operation of the touch screen.

Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.

Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials.

Abstract: The present patent application includes a discussion of a signal compensation apparatus (119). The apparatus is implemented in a digital radiotelephone (101) having diversity receivers (111, 113). The signal compensation apparatus utilizes three control loops and a branch selection switch circuit to substantially diminish the undesired gain and DC offset present in the selected received data signal. Portions of the apparatus are implemented in a digital signal processor (DSP) (249) for rapid adjustment of the control loops when switching to a different receiver branch.

Abstract: A decoder decodes a predetermined binary pattern from within a data stream, wherein the pattern includes a repetitious series of binary digits and each series of digits is composed of 2N bits, N being a positive integer greater than 1, and the first N bits is the complement of the second N bits of the series. The decoder includes a bit synchronizer for synchronizing to the bits of the pattern, a digital phase locked loop for generating a clock signal from the received data, a comparator and memory for analyzing the data stream in an alternating manner so as to generate N paths, wherein each path receives every Nth respective bit of the data stream, and an arithmetic logic unit for calculating and measuring the integrity of the pattern in the received data.
