    摘要： Apparatus for attaching a nose section to the main body of a hand-held optical reader (Wand) is provided to accommodate the replacement of internal lamps illuminating a field of information. A nose attachment having a centrally located aperture encompassed by an integral and externally threaded cylindrical extension is secured to the nose section. The aperture and cylindrical extension are aligned and concentric with the optical image path of the Wand. In attaching the nose section to the Wand main body, the cylindrical extension is passed through an aperture in a partitioning frame of the Wand into which the lamps are seated. A screw-on cap, having a centrally located aperture with internal helical threads complementing the external threads of the nose attachment extension, is screwed onto the extension to secure the nose section to the partitioning frame. An outwardly extending flange integrally formed on the cap extends through opposing apertures of the Wand outer covers to accommodate access by hand. When the lamps are to be removed, a tangential force couple is applied by hand to the flange of the cap to detach the nose section, and thereby expose the lamps. Captive surfaces formed onto the nose attachment and the partitioning frame prevent lateral movement between the nose section and the Wand, and confine the movement of the screw-on cap within the Wand when the nose section is detached.

    摘要： A power controlling network element for a communication system includes a detector for measuring radiation power present in components of radiation; element parts, for example a channel control unit (CCU), transponders and other modules, for at least one of: (i) transmitting to the detector at least some components of input radiation received at the elements parts from the system; and (ii) generating one or more components of radiation and emitting the one or more components to the detector; and a field programmable gate array (FPGA) for receiving data from the detector indicative of radiation power in the components of radiation received at the detector, and for controlling radiation power emitted from or transmitted through the aforementioned element parts so that the components of radiation received at the detector are regulated in power to within predetermined power limits. Such an element is by virtue of the detector and the FPGA capable of providing accurately controlled radiation components which are not subject to overshoot or unacceptable drift.

    摘要： A stepper motor damping control system. Damping is performed by switching the power supply connection(s) of energized motor phase windings alternatively ON and OFF at a predetermined relatively high fixed rate. Said switching is performed using a clock signal information for switching one way and an information denoting equality between a voltage substantially proportional to the current flowing through said motor phase windings with a predetermined sawtooth sloped reference signal synchronized with said clock signal for switching the other way.
