摘要： A door operator for a reversibly operable door, such as a garage door, includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A flexible drive member, such as an endless chain, extends on the frame and is capable of moving the carriage. A drive train is on the frame connected for moving the flexible drive member. A motor housing is mounted on the frame within the motor housing and connected to the drive train. The motor has a shaft extending from the motor housing and engaging the drive train. A bearing assembly that includes metal thrust bearings is on the shaft adjacent to the motor. The metal thrust bearing assembly increases the performance of the electric motor, and thus provides a more powerful motor without changing to a larger motor or otherwise modifying the motor design. The motor is mounted on the frame so as to allow the shaft freely to move axially relative to the motor to permit the shaft to self-align. The rotor thus seeks its position of least resistance and maintains this position without manual adjustment, providing an improvement in motor performance.

摘要： A door operator for a reversibly operable door includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A drive member, specifically a roller chain, extends along the frame and moves the carriage. A drive train is provided within a housing and is connected for moving the drive member, and a control circuit is provided for controlling the drive train to open and close the door. A pair of limit switches is mounted within the housing and connected to the control circuit for stopping the drive train when the door has reached a completed position. A pair of limit cams are adjustably mounted on a limit wheel within the housing and separate from the carriage for engaging the limit switches. The limit wheel, which is separate from the drive member, is connected to the drive train to rotate when the drive train moves the carriage. The placement of limit switches and associated connecting wiring along the frame in the garage ceiling is eliminated. The limit cams can be easily and automatically positioned on the limit wheel by pushing a single switch without any manual movement of the limit switches or of the movable cams that contact the limit switches.

摘要： A garage door operator is disclosed to have a front coupling for a threaded screw of the operator and the rotor of the motor. The coupling includes a first coupling device that is a unitary coupling member with opposing recesses for receiving each of the rotor shaft and an end portion of the screw. The unitary coupling member thereby connects the screw to the motor for torque transmission from the motor. The second coupling device includes a thrust containment device that is supported on the screw, and an intermediate assembly disposed between the thrust containment device and an end portion of the guide rail of the door operator. A retainer component of the intermediate assembly restricts expansion of the thrust containment device.

摘要： A spherical lens formed by fusing a generally homogenous glass lens blank to the distal end of an optical fiber, heating and tensioning the lens blank to separate it in two segments with the segment attached to the optical fiber defining a tapered end, and heating the lens blank above its softening point so that the spherical lens forms. The lens blank is fabricated from a 4 weight percent borosilicate glass having a softening point less than that of the core of the optical fiber. The lens member defines a throat region adjacent the optical fiber whose cross-sectional dimension is substantially greater than the diameter of the optical fiber, but substantially less than the diameter of the spherical lens.

摘要： A fiber optic coupler is formed by assembling a coupler preform having two concentric glass tubes having a gap between them. The shape and/or size of the inner tube relative to the shape and/or size of the outer tube is such that a plurality of output optical fibers can be equally spaced in the gap. An input optical fiber is disposed in an aperture in the inner tube. The input and output fibers extend through the midregion of the resultant coupler preform. The midregion is heated to collapse it about the fibers, and the central portion of the midregion is stretched to reduce the diameter over a predetermined length.

摘要： An overclad fiber optic coupler is formed from a coupler preform including a glass tube having a longitudinal aperture. The aperture is formed of a plurality of similarly shaped side walls, each of which includes a longitudinally extending, inwardly projecting protrusions. The region between each two adjacent protrusions constitutes a corner region. Disposed within the aperture are at least a portion of each of a plurality of glass optical fibers, one fiber being situated in each corner region. The midregion of the tube is collapsed onto the fibers, the protrusions maintaining the fibers in their relative positions. At least a portion of the midregion is stretched to reduce the tube midregion diameter.

摘要： A system and method of identifying, assessing and prioritizing risks are provided. The system and method may include a risk identification module that may identify one or more risks to a business, organization, entity, group or department within the entity, etc. One or more risk variables associated with each identified risk may then be identified. In some examples, the risk variables may be the same or substantially similar for all identified risks. A risk score for each identified risk variable may be determined and an overall risk score for each identified risk may then be determined based on the determined variable risk scores. In some examples, the overall score may be normalized on a predetermined scale. Once an overall score for each risk is determined, the risks having the highest priority may be identified.

摘要： An apparatus for measuring polarization dependent loss is disclosed featuring several fiber optic couplers combined in tandem and oriented such that the PDL noise of the measurement system is reduced to a negligible level. By matching the PDLs of the couplers and vectorally subtracting opposite phases of polarization, the PDL of the measurement system is virtually eliminated. Thus, the PDL noise floor is lowered to near zero and the PDL of the optical device-under-test (DUT) can be accurately measured. The system is relatively inexpensive to implement and offers needed versatility because it measures the PDL of optical devices that operate in a reflection mode or in a forward transmission mode. Thus, it provides one PDL measurement solution for both types of devices.
摘要翻译：公开了一种用于测量偏振相关损耗的装置，其特征在于将多个光纤耦合器串联组合并定向成使得测量系统的PDL噪声降至可忽略的水平。通过匹配耦合器的PDL和矢量减去相反的极化相位，实际上消除了测量系统的PDL。因此，PDL本底降低到接近零，并且可以精确地测量被测光学器件（DUT）的PDL。该系统实现相对便宜并且提供所需的多功能性，因为它测量以反射模式或正向传输模式操作的光学装置的PDL。因此，它为两种类型的设备提供了一个PDL测量解决方案。

摘要： A door operator system for an upward acting sectional or one piece (California-type) garage door includes a DC variable speed motor directly connected to a drive mechanism for moving the door between open and closed positions. A motor control circuit includes circuit components for reversing the direction of rotation of the motor and for delivering a pulse width modulated voltage signal to the motor to control motor speed. A current sensor including a split core transformer and a Hall effect sensor detects motor current and provides a signal to a microcontroller for stopping the motor or stopping and reversing the motor if the motor current reaches a preset limit which is user settable by potentiometers connected to the microcontroller. Magnetic position limit switches and an obstruction detector are operably connected to the microcontroller to provide input signals indicating the state of the door and the control circuit. A motor shaft mounted encoder provides a pulse-type signal to the microcontroller to provide a speed signal and a door position signal. The microcontroller is operable to control operation of the motor to move the door toward an open position at a speed at least twice the speed of movement of the door to a closed position. The encoder and microcontroller detect maximum door travel in the door opening mode and reduce motor speed in subsequent operating cycles if the operator is connected to a one piece door.
