A resonant forward converter at a switching frequency of 10 MHz provides a small volume point-of-load converter for distributed power systems. The leakage inductance of a transformer is made negligibly small relative to the magnetizing inductance of the transformer. This enables a resonant controllable switch on the primary side of a transformer and a secondary side rectified diode to be switched either on or off at the same time. The capacitance across the primary side switch and the secondary ...

The present invention involves a forward light housing assembly for use on a vehicle, specifically a conventional truck, that enhances the aerodynamic characteristics of the vehicle while eliminating any need to modify the vehicle's body or fenders to properly position its headlights and turn signals. The disclosed light housing assembly incorporates both headlights and a turn signal into a single package that can easily be attached to the leading edge of a fender in a way which blends into the ...

A seat assembly including a cushion frame and a back frame with control means operatively interconnecting the frames for allowing the back frame to recline from an upright seat-forming position while preventing forward folding movement and for allowing forward folding movement of the back frame from the upright seat-forming position while preventing reclining movement. Two embodiments are disclosed and in each embodiment the control means includes a C-shaped link pivotally connected to the cushi...

The present invention relates to a forward recumbent posture pod (10) for supporting the anterior torso of an infant residing therein while allowing for substantially unrestricted movement of the infant's limbs and head. The forward recumbent posture pod comprises a pod (12) slidably secured to one end of an arc-shaped spring (14), with the other end of the spring pivotally secured to a base (20) to space the pod away from the base. An infant rests in a cavity (22) of the pod with the infant's l...

A support for a basketball goal. A first support boom is connected at one end to a stationary overhead structure for pivotal movement about a generally horizontal axis between a lower use position and an upper storage position, the other end of the first boom being proportioned and designed to carry such a goal. The first boom carries a pair of roller stops intermediate its ends. A second support boom is connected at one end to the stationary structure for pivotal movement about a second axis an...

A forward planning apparatus comprising in combination a time scale with a plurality of pointers movable together over it in accordance with the passage of time, the pointers being set to indicate given periods of time between them and each representing a stage of an enterprise, and at least one multisided element representing a unit of the enterprise, the sides of said element each bearing an indication for one stage of the enterprise, such element being capable of application to the time scale...

A Darlington output stage is shown in which the saturation voltage is substantially reduced by the incorporation of a complementary transistor. An IC form of the circuit is shown in detail.

A feed-forward amplifier having delay lines formed as microstrip transmission lines, for reliability and low losses, and signal amplifiers that have phase linearity, to match the delay lines, and a relatively high gain. The resulting device can be manufactured more reliably at relatively low cost, but has improved error cancellation performance, improved temperature stability, and is simple to tune after assembly, without removal of components.

A feed forward circuit receives an input signal having at least one carrier therein in a prescribed frequency range. The input signal is applied to a first circuit path having a power amplifier that produces an output signal with a distortion component and to a second circuit path that delays the input signal without distortion. The output signal of the first circuit path is combined with the output signal of the second circuit path to form a signal representative of the distortion component of ...

In a forward converter power supply comprising a transformer having a primary winding connected to a primary circuit and a secondary winding connected to a secondary circuit, and a switching transistor in the primary circuit, an active network snubber in the primary circuit for receiving and storing continuing current from the transformer primary winding upon switching of the transistor and for returning current through the transformer primary winding so as to resent the transformer and thereby ...
