Title: Pulse amplitude modulated chlorophyll fluorometer

Abstract

Chlorophyll fluorometry may be used for detecting toxins in a sample because of changes in micro algae. A portable lab on a chip ("LOAC") based chlorophyll fluorometer may be used for toxin detection and environmental monitoring. In particular, the system may include a microfluidic pulse amplitude modulated ("PAM") chlorophyll fluorometer. The LOAC PAM chlorophyll fluorometer may analyze microalgae and cyanobacteria that grow naturally in source drinking water.

Radar transponder operation with compensation for distortion due to amplitude modulation

Patent Ormesher, Richard C [Albuquerque, NM]; Tise, Bertice L [Albuquerque, NM]; Axline, Jr., Robert M. (Albuquerque, NM)

In radar transponder operation, a variably delayed gating signal is used to gate a received radar pulse and thereby produce a corresponding gated radar pulse for transmission back to the source of the received radar pulse. This compensates for signal distortion due to amplitude modulation on the retransmitted pulse.

Triggerable electro-optic amplitude modulator bias stabilizer for integrated optical devices

Patent Conder, Alan D [Tracy, CA]; Haigh, Ronald E [Tracy, CA]; Hugenberg, Keith F [Livermore, CA]

An improved Mach-Zehnder integrated optical electro-optic modulator is achieved by application and incorporation of a DC bias box containing a laser synchronized trigger circuit, a DC ramp and hold circuit, a modulator transfer function negative peak detector circuit, and an adjustable delay circuit. The DC bias box ramps the DC bias along the transfer function curve to any desired phase or point of operation at which point the RF modulation takes place.

Bi-metallic anode for amplitude modulated magnetron

Patent Neubauer, Michael L.; Dudas, Alan J.; Kahn, Stephen A.

An anode structure for a magnetron provides for low eddy currents and efficient water cooling. The anode structure may be made by machining a bimetal blank including an out layer of a first metal and an inner layer of a second metal and formed by explosion bonding. The second metal has a resistivity lower than first metal and a thermal conductivity higher than the first metal. The machining may result in the anode structure with vanes each having a center (tip) portion made of the second metal and the rest made of the first metal. The machined anode structure maymore » be coated with the second metal. « less

Phase matching of high order harmonic generation using dynamic phase modulation caused by a non-collinear modulation pulse

Patent Cohen, Oren [Boulder, CO]; Kapteyn, Henry C [Boulder, CO]; Mumane, Margaret M [Boulder, CO]

Phase matching high harmonic generation (HHG) uses a single, long duration non-collinear modulating pulse intersecting the driving pulse. A femtosecond driving pulse is focused into an HHG medium (such as a noble gas) to cause high-harmonic generation (HHG), for example in the X-ray region of the spectrum, via electrons separating from and recombining with gas atoms. A non-collinear pulse intersects the driving pulse within the gas, and modulates the field seen by the electrons while separated from their atoms. The modulating pulse is low power and long duration, and its frequency and amplitude is chosen to improve HHG phase matchingmore » « less

Fast repetition rate (FRR) fluorometer and method for measuring fluorescence and photosynthetic parameters

Patent Kolber, Zbigniew [Shoreham, NY]; Falkowski, Paul [Stony Brook, NY]

A fast repetition rate fluorometer device and method for measuring in vivo fluorescence of phytoplankton or higher plants chlorophyll and photosynthetic parameters of phytoplankton or higher plants by illuminating the phytoplankton or higher plants with a series of fast repetition rate excitation flashes effective to bring about and measure resultant changes in fluorescence yield of their Photosystem II. The series of fast repetition rate excitation flashes has a predetermined energy per flash and a rate greater than 10,000 Hz. Also, disclosed is a flasher circuit for producing the series of fast repetition rate flashes.
