Abstract

A system combines complete, ultra-thin cells into a monolithic and robust framework necessary for desalination applications which yields orders of magnitude faster desalination. The electrode pairs are located so that a flow of feed water flows through or around the electrode pairs with the flow perpendicular to sequentially applied electric potentials. The system is controlled to charge the series of electrode pairs sequentially or phased. That means the charging of the second electrode pair is delayed with regard to the charging of the first electrode pair and the charging of a third electrode pair is delayed with respect to the charging of the second electrode pair.

Compact monolithic capacitive discharge unit

Patent Roesler, Alexander W [Tijeras, NM]; Vernon, George E [Rio Rancho, NM]; Hoke, Darren A [Albuquerque, NM]; ...

A compact monolithic capacitive discharge unit (CDU) is disclosed in which a thyristor switch and a flyback charging circuit are both sandwiched about a ceramic energy storage capacitor. The result is a compact rugged assembly which provides a low-inductance current discharge path. The flyback charging circuit preferably includes a low-temperature co-fired ceramic transformer. The CDU can further include one or more ceramic substrates for enclosing the thyristor switch and for holding various passive components used in the flyback charging circuit. A load such as a detonator can also be attached directly to the CDU.

Multiple pulse charge transfer for capacitive deionization of a fluid

Patent Stadermann, Michael; Hunter, Steven L.

The present disclosure relates to a capacitive deionization system which makes use of a controller, a first capacitor acting as a first electrode, a second capacitor acting as a second electrode, and a first inductor for storing energy received from the first capacitor, and transferring the stored energy to the second capacitor. A first plurality of electronic switches are controlled by the controller to control communication between the first inductor and the first capacitor, and between the first inductor and the second capacitor. An additional energy transfer subsystem is included which has a second inductor for receiving energy from themore » « less

Capacitive charge generation apparatus and method for testing circuits

Patent Cole, Jr., Edward I. (Albuquerque, NM); Peterson, Kenneth A [Albuquerque, NM]; Barton, Daniel L [Albuquerque, NM]

An electron beam apparatus and method for testing a circuit. The electron beam apparatus comprises an electron beam incident on an outer surface of an insulating layer overlying one or more electrical conductors of the circuit for generating a time varying or alternating current electrical potential on the surface; and a measurement unit connected to the circuit for measuring an electrical signal capacitively coupled to the electrical conductors to identify and map a conduction state of each of the electrical conductors, with or without an electrical bias signal being applied to the circuit. The electron beam apparatus can further includemore » « less
