A method and apparatus for curing photosensitive materials uses LEDs and an optical concentrator to generate high optical power intensities. An LED array, comprising a plurality of LED assemblies, generates collimated light. A collection lens functions as an optical concentrator and focuses the collimated light to a desired spot size at a desired location. The LED assemblies may be at least partially disposed in a cooling plenum, where the cooling plenum is at least partially defined by the collection lens. Each LED assembly within the LED array may be detachably coupled to a mounting surface, enabling easy replacement of individual LED assemblies within the LED array. The photocuring assembly may also include a redirecting assembly disposed between the collection lens and the desired location that may further concentrate the light at the desired location. The photocuring assembly may include more than one of the above features.

An efficient transmitter is disclosed which comprises a direct current power source and an amplifier for amplifying a drive signal so as to produce a desired signal and a waste energy signal. An antenna is used to transmit the desired signal. A plurality of rectifier stages are connected in a cascade formation and convert the waste energy signal to direct current which is fed to the direct power source. Furthermore, power reflected when an amplifier load deviates from a perfect match in one amplifier stage is sent to a next amplifier stage in the cascade formation so that the reflected power is transferred to the direct power source.

A printed monopole antenna is disclosed having a printed circuit board with a first side and a second side, a monopole radiating element comprising a first conductive trace formed on the printed circuit board first side, and a conductive element comprising a second conductive trace formed on the printed circuit board adjacent the first conductive trace. The second conductive trace defines an extended ground plane which prevents the radiation of currents from that portion of the first conductive trace aligned with the second conductive trace. The second conductive trace may be formed on either side of the printed circuit board. The printed monopole antenna may be modified to operate within two separate frequency bandwidths.

A phase-locked loop incorporates a quadrature modulator for generating constant envelope phase or frequency modulation. Locating the quadrature modulator within the feedback loop or feeding the output signal of the quadrature modulator into the feedback loop permits accurate constant envelope phase modulation of the loop reference oscillator and completely suppresses undesired AM and PM components of the modulated signal.

A method of manufacturing a printed antenna is disclosed which involves the steps of: providing a printed circuit board of desired length and width having a first side, a second side, a feed open, and an open end; fabricating a main radiating element of a desired electrical length on one of the printed circuit board sides; and, overmolding both sides of the printed circuit board. The printed circuit board is made of a dielectric material having a minimum degree of flexibility and the overmolding step is accomplished by injection or insertion molding a low-loss dielectric material on the printed circuit board. In addition, the manufacturing method includes the step of incorporating a feed port with the printed antenna, wherein the main radiating element is coupled to a signal feed portion thereof.

A method and a device for increasing the battery life of a battery in a handheld radio transmitter/receiver are disclosed. The disclosed method comprises the steps of rectifying radio-frequency waste energy which is not radiated from an antenna to produce a direct current and directing that current back to the battery of the handheld radio transmitter/receiver. The disclosed device comprises an amplifier for amplifying a transmit signal and sending the transmit signal to an antenna. The disclosed device also comprises an isolator for diverting energy reflected from the antenna and a rectifier for rectifying that diverted energy to produce a direct current which is supplied back to the battery of the handheld radio transmitter/receiver.

A wire-wound inductor includes a dielectric core, terminals including wire staples that are crimped around the core, and a wire winding disposed about the perimeter of the core and connected to the terminals. A coating such as an adhesive coating is disposed over the wire winding and between the terminals. The process for manufacturing the inductors in a continuous process. Beginning with a spooled material, which may be extruded, inductors are formed on a core material sequentially. The inductors are not physically separated until the final stages of manufacturing, which is in contrast to the prior art method in which each inductor is individually constructed on an individual core that has been manufactured with tight tolerances and wound individually. By virtue of the characteristics of the inductor components, extremely tight tolerances (typically about 0. 0005") can be obtained, resulting in highly controlled inductance values.
