摘要： An apparatus for hands-free turning of sheets in a booklet. A paper clip is attached to sheet(s) in the booklet. The apparatus comprises a swing arm with a magnet for magnetically attaching to the paper clip on the sheet(s). The swing arm sweeps from right-to-left with the sheet attached thereto, thereby turning the sheet over to the back page. This can be operated by a hands-free actuator, such as a foot pedal. The swing arm then makes a return stroke to turn the next sheet. Also disclosed are methods for turning pages in a hands-free manner.

摘要： A sensor system for generating sample analog signals for processing by a signal processing circuit that utilizes non-constant weights includes a plurality of signal generating elements and a switching network having a plurality of switches operably coupled to the plurality of signal generating elements. The switching network is configured to switch the plurality of signal generating elements between a plurality of different configurations. The system includes a dynamic element matching (DEM) control system for controlling the switch network to implement a second order DEM rotation scheme in which the plurality of signal generating elements are switched to each configuration in the plurality of configurations in a first sequence and then switched to each configuration in the plurality in a second sequence, the second sequence being the reverse of the first sequence.

摘要： An image display system implemented with a spatial light modulator (SLM) comprising a plurality of pixel elements each comprises a driver circuit. The driver circuit further comprises at least a first and second transistors cascaded with a first capacitor between a high voltage (Vh) and a ground voltage (Vg) wherein each of the first and second transistors having a breakdown voltage less than the high voltage (Vh). The first transistor receives an input signal to turn on the first and second transistors for discharging the first capacitor and pulling down an output voltage to a ground voltage (Vg) and to turn off the first and second transistors to pull up the output voltage to the high voltage (Vh) wherein each of the first and second transistor is biased to approximately half of the high voltage (Vh/2).

摘要： A method for generating a temperature-compensated timing signal that includes counting, within an update interval, a first number of oscillations of a first micro-electromechanical (MEMS) resonator, a second number of oscillations of a second MEMS resonator and a third number of oscillations of a digitally controlled oscillator (DCO), computing a target DCO count based on the first number and second number of oscillations, computing a loop error signal based on the target DCO count and the third number of oscillations, and modifying an output frequency of a temperature-dependent (DCO) timing signal based on the loop error signal. The duration of the update interval may also be modified based on temperature conditions, and the update interval may also be interrupted and the output frequency immediately adjusted, if a significant temperature change is detected. Thus, dynamic and precise temperature compensation is achieved that accommodates constant, slowly changing, and rapidly changing temperature conditions.

摘要： Embodiments of an oscillator circuit are described. Embodiments described herein include an oscillator circuit suitable for a resonator with relatively high motional impedance, thus requiring relatively high amplification and having relatively high sensitivity to noise. However, the embodiments described are not intended to be limited to use with any particular type of resonator. In one embodiment, alternating current (AC) coupling, or capacitive coupling, is used in part to decouple the bias voltage placed on the resonator from the operating point of the amplifier, allowing one voltage to be high relative to the other. In an embodiment, some legs, or all legs of the circuit that includes drive circuitry and a resonator include differential signaling.
摘要翻译：描述振荡器电路的实施例。本文描述的实施例包括适合于具有较高运动阻抗的谐振器的振荡器电路，因此需要相对较高的放大和对噪声具有较高的灵敏度。然而，所描述的实施例并不旨在限于与任何特定类型的谐振器一起使用。在一个实施例中，交流（AC）耦合或电容耦合被部分地用于将放置在谐振器上的偏置电压与放大器的工作点去耦合，从而允许一个电压相对于另一电压高。在一个实施例中，包括驱动电路和谐振器的电路的一些支路或所有支路包括差分信号。
