Patent number: 9438129Abstract: Input/output power and signal transfer and power and signal isolator device using pulsed, alternating or high frequency signal current having a capacitive structure which provides power and signal limiting control, unidirectional power and signal transfer and input/output decoupling and transceiver-receiver isolation barrier. The device includes at least two decoupled input electrodes arranged in parallel to each other, and at least two decoupled output electrodes arranged in parallel to each other. Each electrode is connected to at least one terminal. Each electrode has a surface that which is opposed to another electrode surface with at least one layer of dielectric material therebetween. The input electrodes are decoupled from the output electrodes by dielectric material and are disposed such that two output electrodes are separately disposed external to the two input electrodes.Type: GrantFiled: September 14, 2012Date of Patent: September 6, 2016Inventors: Cesar Ladron de Guevara, Leonard Davidson

Publication number: 20140034559Abstract: The present invention relates to a means of monitoring and controlling a process step, or steps for a treatable fluid being processed, whereby a sampled volume of the treated fluid is delivered to a vessel, within which the sampled treated fluid emulates the expected reaction or reactions of the treatable fluid being processed within the process step. The sampled volume of the treated fluid is detained, monitored, recorded and analyzed by the present invention. The resulting data is translated into commands that are conveyed to process control devices which control the processing of the treatable fluid. Sampling and analyzing of the treatable fluid is automatically repeated on a cyclical basis.Type: ApplicationFiled: October 15, 2013Publication date: February 6, 2014Inventors: Cesar Ladron de Guevara, Leonard Davidson

Publication number: 20040007523Abstract: A wastewater treatment process that provides improved reduction of total solids through endogenous respiration while reducing biochemical oxygen demand and utilizing biological, nutrient reduction. The wastewater treatment process uses an efficient aeration delivery system to drastically reduce the time needed to oxidize organic matter, and recirculates, shreds, and homogenizes the organic matter and microorganisms and oxygenates the entire mass many more times than traditional systems resulting in a greater biological solids digestion rate.Type: ApplicationFiled: July 9, 2003Publication date: January 15, 2004Applicant: PREMIER WASTEWATER INTERNATIONAL, LLCInventors: Paul G. Gabon, Leonard Davidson, H. Matthew Russell, Martin Perry Johnson

Patent number: 5615123Abstract: A method of and apparatus for creating and producing printed card products such as greeting cards for various applications, whereby a customer can select a card product for a desired application and customize or personalize certain portions of the selected card product. A terminal area or kiosk is provided at which the customer selects from a monitor screen display one of a number of different general applications for which he/she wants to obtain a card product. Upon entry of the selection via, e.g., a transparent touch-sensitive plate on the monitor screen, one or more pre-stored groups of card product design formats pertaining to the selected general application are determined, and further inquiries are made via the monitor screen to elicit certain information relating to a specific use or application for the desired card product.Type: GrantFiled: April 2, 1991Date of Patent: March 25, 1997Assignee: CreataCard, Inc.Inventors: Leonard Davidson, Matt Russell, Scott Allred, Michael S.

Patent number: H1708Abstract: A method of and apparatus for creating and vending printed card products such as greeting cards is disclosed, whereby a customer can select a card product for a desired application and customize or personalize certain portions of the selected card product. A terminal area or kiosk is provided at which the customer selects from a monitor screen display one of a number of different selection criterion for which he/she wants to obtain a card product. There may be multiple levels of selection criteria. Upon entry of the selection via, e.g., a transparent touch-sensitive plate on the monitor screen, one or more pre-stored groups of card product design formats pertaining to the selected selection criterion are determined, and the customer is prompted to select a particular card format to customize. The card product designs may include separate graphics, text and spaces for insertion of customized user messages, and these elements may be stored in a compressed format.Type: GrantFiled: November 26, 1991Date of Patent: February 3, 1998Assignee: CreataCard, Inc.Inventors: Leonard Davidson, H.
