摘要:
An optical module that may be used in small-form factor pluggable applications includes a delatching/latching mechanism. The optical module may be an optical transceiver, for example, and the delatching/latching mechanism may allow for improved insertion and removal of the optical module from a cage in a computer board assembly. A latching assembly that assists in latching and delatching may include a latching member having a slotted mating element that is in contact with, and rotates relative to a substantially-fixed pivot element. Rotation may be achieved via a rotatable actuator having a cam engaging a cam follower. Numerous example biasing apparatuses are described to bias the latching assembly to its latched position and to promote contact between the mating element and the pivot element.

The present invention provides BZPA products with improved flowability and two methods of producing such BZPA products. Both methods successfully produce BZPA products that are not prone to agglomerate upon storage, and thus the flowability of such BZPA products does not degrade over time. The first method includes mechanically forming the BZPA crystals into large compacted pellets or briquettes without the introduction of any additives or binders. The compacted pellets are large enough that the physical and chemical effects that occur on the surface of small crystal particles are eliminated or minimized, but small enough that the BZPA can be easily handled and used in commercial applications. The second method includes adding a substantially inert anti-caking agent to the BZPA crystals to minimize or retard their tendency to agglomerate. The preferred anti-caking agent is silicon dioxide (SiO2), which is blended with the BZPA crystals in small amounts.

The present invention is directed to a system and method for tuning an optical fiber Bragg grating by using a circular mechanism which uniformly stretches the fiber along its length while at the same time preserving the minimal size for stretching.
摘要:
Temperature compensated fiber stretching is accomplished by amplifying with a unique flexure the relative displacement between a rigid frame and a longitudinal spacing element. For passive compensation, relative displacement results from differential thermal expansion between the frame and the longitudinal spacer. For active thermal compensation and/or for wavelength tuning of an embedded fiber Bragg grating, relative displacement results from combining differential thermal expansion with active feedback length control of the longitudinal spacer. The feedback control can stabilize using length feedback from a displacement sensor or actively control length using temperature feedback, including logic elements, for example algorithms or look up tables. In an optical system, combined passive compensation and active control with flexure amplification provide superior thermal wavelength stability and tuning range. In some embodiments, the rigid frame and the flexure are of the same material and can be formed as a single monolithic piece.

A valve assembly is used to start an engine with a minimum of electrical power. The valve assembly provides a low initial fuel flow rate to the engine. Upon initiation of combustion in an engine combustion chamber, the resulting increase in fluid pressure is transmitted through the flow of fuel to the valve assembly. The pressure transmitted from the combustion chamber is effective to actuate the valve assembly to increase the rate of flow of fuel to the engine. The valve assembly includes an inlet valve which is opened to enable fuel to flow at a relatively low rate through an initial flow control orifice to the engine combustion chamber. Upon initiation of burning of fuel, the increase in pressure is transmitted to the valve assembly and is effective to move a main valve member to open a variable size main flow control orifice. Opening of the variable size main flow control orifice increases the rate of flow of fuel to the combustion chamber.

A coplanar sensor includes a plurality of first sensing units and a plurality of second sensing units. Each of the first sensing units includes a plurality of first electrode blocks that are spaced apart from each other in a first direction, and a first connecting line that is electrically coupled to the first electrode blocks. Each of the second sensing units includes a plurality of second electrode blocks that are spaced apart from each other in a second direction intersecting the first direction, and a second connecting line that is electrically coupled to the second electrode blocks. Each of the first electrode blocks has a first sensing surface. Each of the second electrode blocks has a second sensing surface. The first sensing surfaces of the first electrode blocks and the second sensing surfaces of the second electrode blocks are coplanar.

A calibration method for an industrial robot includes receiving a first model of the industrial robot, the first model is synchronized with an attitude state of the industrial robot located at a specific position in an actual environment; receiving an environment model around the industrial robot, the environment model including a second model of the industrial robot; obtaining registration information of the second model, at least by selecting at least three corresponding non-collinear point pairs in the first model and the second model to perform registration; and based on the registration information, calibrating a coordinate system of the environment model to a base coordinate system of the industrial robot.

A process for the efficient capture of CO2 and sulfur from combustion flue gas streams and gasification based fuel gas mixtures using regenerable and recyclable calcium based sorbents. The regeneration of the calcium sorbent is accomplished by hydrating the sorbent at high temperatures of about 600° C. and a pressure higher than 6 bars to lower the parasitic energy consumption.

A power monitoring system uses a low loss reflective element to partially split the output laser beams from an array of laser sources, in a parallel configuration, to produce a monitor beams for each laser source. Each of these monitor beams may propagate within the reflective element in a lossless manner under total internal reflection and into one of a plurality of photodiodes that sense an optical characteristic such as output beam intensity, where this sensed signal is then used as part of a feedback control to control operation of the laser sources in the array.
