摘要： An apparatus for controlling the speed of an AC motor comprising a switch adapted to be coupled in parallel with power terminals for the AC motor; a capacitor coupled in series with the parallel combination of the switch and the motor; the capacitor adapted to provide an AC supply voltage from an AC source to the parallel circuit comprising the motor and the switch; and a control circuit for controlling the conduction time of the switch in order to vary the speed of the motor. The switch is preferably pulse-width modulated at a frequency twice the line frequency of the AC supply voltage, and the switch is turned on when the voltage across the AC motor is zero volts. The apparatus is operable to provide for continuously variable control of the motor speed while minimizing acoustic noise in the motor.

摘要： A power supply for a load control device is disposed in series with an AC voltage source and a load and generates a substantially DC voltage for powering a controller of the load control device. The power supply is operable to provide substantially all voltage provided by the AC voltage source to the load and includes a controllably conductive device, a triggering device, and a charging circuit. The charging circuit is operable to charge an energy storage device and to conduct current to the load when the controllably conductive device is non-conductive. The controllably conductive device begins conducting the full load current when the energy storage device has charged to a predetermined amount of energy. Before the controllably conductive device begins to conduct, only a minimal voltage, which is substantially the same as the break-over voltage of the triggering circuit, develops across the power supply to allow the energy storage device to charge.

摘要： An AC motor speed controller includes a plurality of capacitors that may be selectively switched, by means of controllably conductive switches, into series electrical connection with an AC motor and an AC voltage source to control the speed of the motor. To change the speed of the motor, a control circuit renders a first switch conductive, in response to a first detected AC voltage zero crossing, to charge a first capacitor to a predetermined voltage. The control circuit then renders a second switch conductive, in response to a subsequent second detected AC voltage zero crossing, to charge a second capacitor to the predetermined voltage. The control circuit then renders both switches simultaneously conductive at a predetermined time after a subsequent third detected AC voltage zero crossing. The capacitors will thereby be charged to the same voltage prior to being switched into series with the motor, thereby resulting in reduced acoustic noise when changing motor speeds.

摘要： A load control device is adapted to be disposed in series with an AC voltage source and an electrical load and is operable to provide substantially all voltage provided by the AC voltage source to the load. The load control device comprises a controllably conductive device, a controller, a zero-crossing detector, and a power supply for generating a substantially DC voltage for powering the controller. The power supply is operable to charge an energy storage device to a predetermined amount of energy each half-cycle. The controller is operable to determine when the power supply has stopped charging from the zero-crossing detector each half-cycle, and to immediately render the controllably conductive device conductive to conduct the full load current. Before the controllably conductive device begins to conduct each half-cycle, only a minimal voltage develops across the power supply to allow the energy storage device to charge.

摘要： A waveguide network has a first port and a plurality of second ports connected to a two dimensional rectangular array of antenna elements. The second ports and antenna elements are oriented in a fixed direction. The waveguide network includes at least three successive sets of junctions and bends including a first set connected to the first port and a last set connected to the second ports. The junctions and bends in each set are all E-plane junctions and E-plane bends or are all H-plane junctions and H-plane bends, and successive sets alternate between a set of E-plane junctions and E-plane bends and a set of H-plane junctions and H-plane bends. The bends in at least one set lead in the fixed direction, and the bends in at least one other set, not including the last set, lead in a direction opposite to the first direction. Preferably, the waveguide bends in each set, other than the first set and possibly the last set, lead in a direction opposite to the bends in the previous set. The waveguide network is conveniently assembled from one piece containing all of the E-plane junctions and E-plane bends and another containing all of the H-plane junctions and H-plane bends.

摘要： Systems and methods can facilitate identifying 2D content in media that is suitable for conversion into 3D content, and converting the suitable 2D content into 3D content. The identifying can be based on quality criteria applied to the 2D content. For 2D content converted into 3D content, a user can be offered a choice between viewing the content in its original 2D form, or viewing the content in its converted, 3D form. The systems and methods can thereby provide users with greater choice of content and an enhanced viewing experience.
