摘要： A signal processing circuit and processing method are provided for measuring an analog signal from a photo-detector. Generally, the method includes steps of: (i) sampling and storing a characteristic of the signal at a first predetermined time following a reset of the circuit; (ii) sampling the characteristic of the signal at a second predetermined time following a reset or initialization of the circuit; (iii) determining a difference between the stored characteristic of the signal sampled at the first predetermined time and the characteristic of the signal sampled at the second predetermined time; and (iv) converting the determined difference to a digital value and determining a slope of the signal from the digital value and the difference between the first and second predetermined times. Thus, the measurement of the slope is independent of and substantially unaffected by absolute values of the characteristics measured at the first and second predetermined times.

摘要： A signal processor and processing method are provided for measuring current received from a photo-detector. Generally, the processor includes a transimpedance amplifier (TIA) to integrate a current received from a photo-detector in the optical navigation system to generate a voltage signal having a slope that is proportional to the received current, and a comparator having a first input coupled to an output of the TIA to receive the voltage signal, and a second, inverting, input coupled to a threshold voltage. The comparator is configured to compare the voltage signal to the threshold voltage and to generate an output pulse having a predetermined voltage and a duration or width that is a function of the received current.

摘要： A method of resetting the mirrors (11, 21) of the mirror elements of a digital micro-mechanical device (DMD) (10, 20). A bias voltage is applied to the mirror elements and the surface upon which they land, but is removed after the address voltage has been switched. (FIG. 4). Immediately before the bias is removed, a reset voltage is added to the bias voltage. The reset voltage signal is comprised of a number of pulses at a frequency that matches the resonant frequency of the mirrors. The magnitude of the reset voltage results in a total applied voltage that permits vibrational energy to build but that is insufficient to cause the mirrors to become unstuck until the end of the reset signal. In other words, the magnitude of the reset voltage is small relative to that of the bias voltage.

摘要： In one embodiment, a micro electromechanical system (MEMS) driver circuit receives a pulse-width modulated (PWM) signal and uses it to control a voltage at a MEMS cell. The driver circuit further includes a current source, a capacitor, and a reset circuit that can discharge the capacitor. The voltage at the MEMS cell can be controlled in proportion to the pulse width of the PWM signal. In another embodiment disclosed, a MEMS driver circuit receives a first PWM signal and a second PWM signal. Each PWM signal is coupled to a current source. One current source can provide a course current control and the other current source can provide fine current control. The driver circuit can further include a capacitor and a reset circuit for discharging the capacitor. The voltage at the MEMS cell can be controlled in proportion to a summation of the first and second current sources. According to another aspect of the embodiments, a method of controlling a voltage at a MEMS cell is disclosed. The method includes the steps of receiving a PWM signal, controlling a current source with the PWM signal, and adjusting the voltage at the MEMS cell in proportion to a pulse width of the PWM signal.

摘要： An apparatus for measuring wavelength composition and power of a dispersed spectrum of light comprises a diffractive light modulator and a detector. The diffractive light modulator comprises an array of light modulating pixels operable in a first mode and a second mode. In operation, the dispersed spectrum of light illuminates the diffractive light modulator along the array of light modulating pixels, which selectively directs a subset of the dispersed spectrum of light into the first mode while directing a remainder of the dispersed spectrum of light into the second mode. The detector is optically coupled to the diffractive light modulator. In operation, the detector detects the subset of the dispersed spectrum of light while not detecting the remainder of the dispersed spectrum of light. Each of the light modulating pixels is controlled by signals sent from a controller. The signals comprise a time division multiplex modulation, a code division multiplex modulation, or a combination thereof.

摘要： A process for chemical vapor deposition of blanket tungsten thin films on titanium nitride proceeds by hydrogen reduction of tungsten hexafluoride at temperatures of 200 to 500.degree. C. Tungsten film nucleation is preferably facilitated by partial removal of the oxidized surface of titanium nitride or titanium nitride coated substrates by a sputter cleaning process prior to the tungsten CVD. The process differs in part from other processes in that deposition proceeds rapidly on titanium nitride without a significant nucleation period without the addition of other chemical compounds such as silane. The sputter cleaning process preferably takes place in an inert vacuum environment that protects the substrate from atmosphere and oxygen until the tungsten CVD step occurs. The process is particularly advantageous where the substrate has a titanium nitride surface that had been created in a separate location such as by a reactive sputter coating process from which the substrate must be transferred through ambient atmosphere containing oxygen. The advantages of the invention can be partially attained or enhanced by isolating the substrates from an oxygen containing environment between the creation of the titanium nitride surface and the initiating of the tungsten CVD.

摘要： A method of providing drive signals to an illuminator module having a plurality of channels in a printing application. Binary image data including image bits is provided from a data source to the illuminator module. Each image bit is converted to a multi-bit amplitude value within the illuminator module, wherein the conversion of each image bit to the multi-bit amplitude value depends at least on a value of the image bit and which channel is associated with the image bit. Pulse width modulation (PWM) may be applied to the drive signals using programmable transition delays. Apparatus for performing the aforementioned method are also disclosed.
