| 20100184840 | PRIMARY MICRO RNA EXPRESSION CASSETTE - This invention relates to inhibition of hepatitis gene expression. More specifically, the invention relates to a method of using RNA sequences to inhibit Hepatitis B and C Virus replication. Expression cassettes that include DNA sequences derived from endogenous micro RNAs (miRs) are used in the method and are transcribed by Pol II promoters, and then processed to generate sequences that are specific to target hepatitis virus sequences (RNAi effecter sequences). The RNAi effecter sequences can target the selected hepatitis virus sequences resulting in gene silencing or transcriptional inhibition of the hepatitis virus gene. The expression cassettes may be delivered in vitro or in vivo to host cells. A pharmaceutical composition containing the expression cassettes is also claimed. | 07-22-2010 |

| 20090039902 | METHODS AND SYSTEMS FOR DETECTING A CAPACITANCE USING SIGMA-DELTA MEASUREMENT TECHNIQUES - Methods, systems and devices are described for detecting a measurable capacitance using sigma-delta measurement techniques. According to various embodiments, a voltage is applied to the measurable capacitance using a first switch. The measurable capacitance is allowed to share charge with a passive network. If the charge on the passive network is past a threshold value, then the charge on the passive network is changed by a known amount for a sufficient number of repetitions until the measurable capacitance can be detected. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to a button, slider, touchpad or other input sensor. | 02-12-2009 |
| 20090174416 | METHODS AND SYSTEMS FOR DETECTING A CAPACITANCE USING SWITCHED CHARGE TRANSFER TECHNIQUES - Methods, systems and devices are described for detecting a measurable capacitance using charge transfer techniques. According to various embodiments, a charge transfer process is performed for two or more times. During the charge transfer process, a pre-determined voltage is applied to the measurable capacitance, and the measurable capacitance is then allowed to share charge with a filter capacitance through a passive impedance that remains coupled to both the measurable capacitance and to the filter capacitance throughout the charge transfer process. The value of the measurable capacitance can then be determined as a function of a representation of a charge on the filter capacitance and the number of times that the charge transfer process was performed. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to an input sensor. | 07-09-2009 |
| 20090322355 | OBJECT POSITION SENSING APPARATUS - An object position sensing apparatus including a substrate, a conductive crossbar, and a plurality of resistive elements coupled to the crossbar is described. The resistive elements are coupled to circuitry that can apply an excitation signal, such as a voltage change, to the resistive elements. For each resistive element, an electrical effect responsive to the excitation signal, such as a change in charge flowing to the resistive element, is determined. When an object is proximate to the plurality of resistive elements, the electrical effects change, and a position of the object in one or multiple dimensions can be determined from changes in the electrical effects. | 12-31-2009 |

| 20120098527 | TRANSDUCER - A transducer is described for use in a position sensor. The transducer has a magnetic field concentrating member, such as an elongate ferrite rod, a first coil operable, in use, to couple with a first portion of the magnetic field concentrating member positioned adjacent the first coil and a second coil operable, in use, to couple with a second portion of the magnetic field concentrating member positioned adjacent the second coil, the second portion being spaced along the magnetic field concentrating member from the first portion. The transducer also comprises a resonator having a coil wound around a portion of said magnetic field concentrating member which is located between said first and second portions. The transducer is arranged so that, during use, the electromagnetic coupling between the resonator and at least one of the first and second coils varies as a function of the relative position between the elongate field concentrating member and that coil. In this way, separate processing electronics can process the signals obtained from the transducer to determine the desired position information. | 04-26-2012 |

| 20100238121 | TRANSDUCER - A transducer for a position sensor is described. The transducer comprises a single laminate sensor board carrying a plurality of windings formed by conductors on one or more layers of the sensor board, the windings being arrayed over a first area of the sensor board; and detection circuitry mounted on another layer of the sensor board over a second area of the circuit board and electrically coupled to said windings, said detection circuitry having a first mode of operation in which signals inductively coupled to or from said windings are detected and a second mode of operation in which signals capacitively coupled to or from said windings are detected. The windings and detection circuitry are arranged on the sensor board so that said first and second areas oppose each other. A position sensor incorporating the transducer is also described. | 09-23-2010 |

| 20090193243 | Dual Mode Power-Saving Computing System - The present invention relates to a data processing system comprising both a high performance computing sub-system having typical high power consumption and a low performance subsystem requiring less power. The data processing system acts as a single computing device by moving the execution of software from the low performance subsystem to the high performance subsystem when high computing power is needed and vice versa when low computing performance is sufficient, allowing in the latter case to put the high performance subsystem into a power saving state. The invention relates also to related algorithms. | 07-30-2009 |
