A power controller for applying power to an induction motor or similar AC load has a variable drive circuit for staring and switching a portion of the AC input line power. In one mode, the input line power is fed straight through to the load. In another mode, the AC waveform is reshaped to improve the power factor or to boost its RMS value, e.g., for brownout protection. In a further mode the output power can be provided at a different frequency from the input line power. Vector control increases efficiency through power optimization, with sensing of load requirements. Sensing of regeneration pulses at the commencement of a half cycle can be employed for direct sensing of motor speed or load.

A beam shaping antenna matrix for use in wireless cell towers that is manually-configured at a patch panel by a wireless operator based on selection of a desired beam size and point of direction. The traffic matrix allows a wireless operator to sculpt and resculpt the beams to accommodate demographic or other changes preferably without a large amount of hardware or intensive processing capability.

Disclosed herein is an improved high-efficiency solar-charging electric window candle comprising a base adapted to sit securely upon a window sill. The base includes a footer formed with a battery compartment accessible through a bottom hatch, and a riser protruding upwardly from the footer with upwardly inclined side surfaces. The riser also has a compartment for enclosing a circuit board, and a vertically-oriented collar. A rechargeable battery is mounted in the footer of said base, and a hollow cylindrical candle body is inserted in the collar of the base riser, and a bulb assembly comprising a white LED is mounted atop the candle body. A circuit board is enclosed in the riser and includes two circuits: a current pump for supplying a pulsed current, and a photosensing circuit for sensing ambient light levels. The charge pump circuit reduces current requirements of the white LED, and the photosensing circuit automatically detects ambient light levels and illuminates the white LED while disconnecting the rechargeable battery, or vice versa, depending on whether there is sufficient ambient light.

The invention relates to an integrated optical fiber melting module which comprises a melting base and a platform cover which are buckled mutually, wherein two fiber winding zones for winding fibers are arranged on the melting base, a welding zone for welding the optical fibers is arranged between the two fiber winding zones, and gaps are reserved among the welding zone and the two fiber winding zones. Upper fiber storing rails and lower fiber storing rails are arranged in the fiber winding zones and partitioned through a plurality of fiber blocking plates. An external optical fiber enters into a welding platform positioned in the middle directly through the upper fiber storing rails and is welded with a distribution tail fiber on the welding platform. The distribution tail fiber passes through coiled paths of the upper fiber storing rails and the lower fiber storing rails and an adapter clamping seat to be connected with users. Different from the conventional design that an optical fiber distribution plate and a welding plate are split, the integrated optical fiber melting module integrates the optical fiber distribution plate and the welding plate, coiled paths of the external optical fiber and the distribution tail fiber are independent to each other and are not overlapped, and therefore, convenience is brought to uses to perform on-site operation.

A rotor assembly for mounting a rotor to a motor shaft having a rotor with a centrally positioned central bore, the diameter of which is slightly larger than a diameter of the motor shaft, a first stepped bore intersecting the central bore and being aligned along a first axis of the rotor, and a second stepped bore also intersecting the central bore and being aligned along a second axis of the rotor. A first cam fastener is disposed within the first stepped bore, and a second cam fastener is disposed within the second stepped bore. Upon rotating the first and second cam fasteners, they engage the motor shaft thereby securely clamping the rotor to the motor shaft.

A cyclonic portable vacuum cleaner / dust collector has a cyclonic chamber and a filter chamber. The filter chamber contains a filter cartridge with a hollow core positioned over the discharge opening of a motor plate that closes the filter chamber. A vacuum blower is mounted on the motor plate, with an intake tube at the discharge opening of the motor plate. An anti-deflagration screen mounted upon the discharge opening of the cover plate of the filter chamber. The anti-deflagration screen is in the form of a metal mesh creating a multiplicity of small passages to permit exhaust air flow from the filter chamber but blocking any flame front. The screen may be hemispherically domed.

A regular hexagonal paper box relates to a method for making a paper vessel.

The invention provides a novel method for designing a communication protocol of high-voltage and direct-current (HVDC) thyristor valve base electric equipment. Based on the controller area network (CAN) protocol, the communication protocol between a pole control system and the valve base electric equipment is set according to different working conditions of a thyristor valve, and information exchange between the valve base electric equipment and the pole control system can be completed by adopting a serial coding mode. The design is simple, clear, reliable and stable, and contains all the basic working conditions of thyristor valve operation. Byadopting the communication protocol, besides the basic communication requirement between the pole control system and the valve base electric equipment can be met, the strong interference resistance of a CAN bus can be introduced to a thyristor valve secondary control system to greatly improve the operation reliability of the system. A multi-master CAN networking communication mode is adopted between the valve base electric equipment and a control protective system, and valve base electronics (VBE) can monitor status changes at any time occurring in the thyristor valve and report the detection information to the control protective system. The networking mode ensures real time performance of monitoring the valve by the VBE.
