    摘要： A method is provided for sensing an environmental effect upon a sensing element and includes exposing the sensing element into the environmental effect, producing a light signal in the sensing element, modulating the light signal with a modulation signal, and determining a path length of the light signal as a function of the modulation signal. A fiber optic sensor is provided that includes a light source producing a light, a sensing element optically coupled to the light source such that the light propagates through the sensing element, a detector optically coupled to the sensing element. The detector detects light intensity propagating in the sensing element. An electronics processor receives the detector output and produces a modulation signal for the light. The processor further produces an output signal indicative of the environmental effect as a function of the modulation signal.

    摘要： A surface abrader apparatus includes a casing, a motor mounted on the casing, one or more working tools, and an operating mechanism mounted to the casing and supporting the working tools outside of the casing. The operating mechanism is drivingly coupled to the motor for causing an impacting movement of the working tools against a workpiece in response to selected operation by the motor. The operating mechanism includes one or more elongated shafts reciprocally mounted in the casing parallel to one another and having same one ends extending from the casing, a drive shaft rotatably mounted in the casing between and parallel to the shafts and rotatably driven by the motor, and coil springs and cam elements for causing lifting and releasing of the shafts and the working tools, such as impact abrading heads, mounted on the same one ends of the shafts to produce impact movements of the tools.

    摘要： A single-frequency fiber-optic ring laser exhibits improved frequency stability, reduced laser intensity noise, broad tunability and narrow linewidth. The fiber-optic ring laser includes a ring-resonator with a length of single-mode optical fiber, a gain medium of rare earth-doped fiber, a broad-band fiber Fabry-Perot filter for wavelength tuning of the laser, a narrow-band fiber Fabry-Perot filter for suppression of longitudinal ring modes and an optical isolator for preventing interetalon interactions between the tandem fiber Fabry-Perot filters. Selective positioning of the tandem fiber Fabry-Perot filters, relative to the ring laser's gain medium and output coupler, results in laser intensity noise reduction to the standard quantum limit.

    摘要： The offset between a reference clock output signal and a target clock output signal are measured during a predetermined period. Based on the measurement, an offset signal is generated. The offset signal is integrated into an average offset signal value, wherein the period of integration is the predetermined phase measurement time. The target clock is adjusted based on the average offset signal value so that the offset signal magnitude value approaches a predetermined limit. The process is iterated until the clocks are aligned within a predetermined tolerance.

    摘要： Finger navigation methods, devices and systems are disclosed. In one embodiment the system comprises a light source configured to radiate a light beam towards a tactile surface. The system also comprises a photo detector module configured to sense speckle beams emitted by a target surface navigating the tactile surface in response to light hitting the target surface. The system further comprises a processor configured to track a movement of the target surface with respect to the tactile surface based on output from the photo detector module and a conductor structure for capacitive sensing of the target surface with respect to the tactile surface. The conductor structure is configured to determine a plurality of navigational functionalities based on the capacitive sensing of the target surface with respect to the tactile surface, including at least one of single click, double click, and scrolling.

    摘要： A token bucket instantiation regulate packets in a traffic flow stream based on a predetermined peak traffic flow rate. The token bucket size is nominally set to zero. An evaluation is made at a device that has received a given packet. The packet is considered conforming and is passed from the device if the token depth of the bucket is zero or greater. The token depth is decreased by the number of byes in the packet that was passed. The token depth is continuously replenished at a predetermined token rate until the predetermined bucket size is attained (the bucket is full). A received packet is deemed nonconforming if the token depth is less than zero; the non-conforming packet is not passed but is processed according to non-conforming criteria. Token bucket instantiations may be implemented in hardware, software or firmware for each traffic flow to regulate traffic to a given user.
