A novel phase locked loop design utilizing novel phase-frequency detector, charge pump, loop filter and voltage controlled oscillator is disclosed. The phase-frequency detector includes a dual reset D-flip flop for use in multi-GHz phase locked loops. Traditional dead zone issues associated with phase frequency detector are improved/addressed by use with a charge transfer-based PLL charge pump.

Phase frequency detector and accurate low jitter high frequency wide-band phase lock loop

The present invention relates to passive phased injection locked circuit and ring-based voltage controlled oscillators. A passive phased injection locked circuit comprises first and second transmission lines, each has a plurality of discrete elements, that are operative to delay the phase of AC signal. Between the first and second transmission lines, a capacitor network is formed to advance the phases of the AC signal in concert along the transmission lines. For the ring-based voltage controlled oscillators, each of the first and second transmission lines has an odd number of discrete elements.

Apparatus for containing oil and/or gas leakage from a drilling operation (off-shore or on-shore) comprised of an expandable membrane surrounding a central spline, an apparatus adapted to the removal of the captured oil or gas, and a blowout-handling 'fuse' capability. The bottom section of the off-shore version includes operator-controlled extension members to expand the membrane to fully surround the drill site. Any further leakage from the well site will further expand the membrane from the spline sections as it moves upward. When the leaked material reaches the top an extraction apparatus included allows it to be extracted safely.

Oil leak containment system and method

Disclosed is an electrical transformer for improved transformer power capacity and efficiency designed by the application of disclosed design considerations. One embodiment design consideration is a method to configure power transformer windings wherein the minimum distance of the primary windings from the winding axis/core center is greater (the primary windings are more distal) from the winding axis than the minimum distance of the secondary windings, which are wound around the minimum interior core diameter. This design consideration is extended from single bobbin transformer designs to split bobbin designs, with the requisite distal increase of the primary windings (from the core axis) geometrically provided by an enlarged core bobbin center leg (axial) dimension beneath the primary winding window. Another disclosed design consideration is to fix the primary winding length relationship to the core weight for given transformer specifications in accordance with the disclosed unexpected experimental results and formula.

Transformer with improved power handling capacity

An imaging method and apparatus are provided, including a light source emitting a polarized light beam, and an optical assembly including a control layer and/or a light reflection surface. The control layer advantageously allows for control over the properties of a generated evanescent wave to optimize an image of a specimen array within the evanescent wave. The light reflection surface includes coupling means used to couple a receptor/capture agent advantageously allowing for flexible control over receptor specific regions.

Imaging method and apparatus

Methods and apparatus for scanning of a microarray to provide an image of the microarray are disclosed. Data related to change in polarization state of a scanning light beam for individual points or lines or other portion of the microarray are collected and processed to image the microarray at high resolution and speed.

Microarray scanning

The placement of solder 'balls' in a Ball Grid Array is accomplished by placing a solder strip in contact with the top surface of the ball grid array carrier. The pulsing of a laser directed at the solder in discrete positions permits the transfer of the solder to the gold dot, of the array of dots, on the carrier in registry with the laser output when activated. Selective solder placement is possible and increasingly higher throughput is achieved by the use of laser diode bars or optical fiber fans to effect solder transfer to a plurality of dots of the array simultaneously. The entire process can be automated by making the solder strip continuous through a recycling station arranged along a path along which the solder strip moves to the position where the carrier and the solder strip are moved into juxtaposition. The use of a transparent strip with a pattern of holes filled with solder paste permits easy transfer of the solder to the gold dots or islands on the carrier in registry with laser beam.

Apparatus and method for forming solder bonding pads

Artificial heart type devices are made into practical heart assist devices by making the blood chambers of the device disposable or by adapting the blood chambers to accept disposable inserts. The inserts have extensions which protrude through the inlet and outlet ports of the chambers to connect to the blood system of a living body.

Pump system suitable as a heart assist device

A conductorless transfer is provided for a large-gap tolerant Permalloy pattern for moving magnetic bubbles. The transfer capitalizes on the symmetry of the elements for enabling a field reversal to achieve transfer.
