Patent number: 11322677Abstract: The invention involves providing a reset signal before and or after one or more actuation signals to an electroactive polymer structure of an actuator. The reset signal can cause relaxation of defects such as e.g. trapped charge, dipoles and/or others in the EAP or EAP structure so that upon a subsequent activation using a drive signal, the initial actuation state is defined to be more constant than without use of the reset signal. Hence the actuation 5 output of a device employing the invention is more reproducible. The invention is applicable to actuator devices that have an electroactive polymer structure including an EAP material, where the structure is capable of providing a mechanical actuation upon subjection of at least part of the EAP material to an electrical drive signal.Type: GrantFiled: May 15, 2017Date of Patent: May 3, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Roland Alexander Van De Molengraaf, Mark Thomas Johnson, Cornelis Petrus Hendriks, Daan Anton Van Den Ende

Publication number: 20150044386Abstract: Matching layers improve the performance of ultrasonic transducers. Such layers have traditionally required significant effort and expense to be added to ultrasonic transducers. The present invention discloses a method of producing ultrasonic transducers with a matching layer, specifically for ultrasonic transducers utilizing piezopolymer transducer materials. Rather than the conventional method of forming the piezopolymer on a substrate and then attaching a matching layer through which the transducer emits its ultrasound energy, we teach depositing the piezopolymer on a substrate that also serves as a matching layer through which the ultrasound is emitted. We also teach depositing an additional shield layer for reducing electromagnetic interference. Methods of how to select materials and modify their ultrasonic characteristics are also discussed.Type: ApplicationFiled: September 17, 2013Publication date: February 12, 2015Applicant: DVX, LLCInventors: David Vilkomerson, Thomas Chilipka

In the first step of the process a mixture of magnetic carrier beads and a conductive powder is prepared in the sump of the deposition unit; the mixture forms a magnetic brush on the sleeve of the deposition unit. In the second step of the process, the substrate is positioned away from the magnetic brush to form an air gap. In the third step of the process, a voltage is applied between the substrate and the sleeve of the deposition unit in order to produce a large asymmetry between the magnetic brush and said substrate such that the electric field at the magnetic brush is at least 3.0 times as great as the electric field at the substrate. In the fourth step of the process, conductive powder is deposited onto the substrate.Type: GrantFiled: December 4, 2009Date of Patent: November 22, 2011Inventors: Dan A. Hays, Peter J.

Patent number: 7972661Abstract: An electrospraying apparatus and/or method is used to coat particles. For example, a flow including at least one liquid suspension may be provided through at least one opening at a spray dispenser end. The flow includes at least particles and a coating material. A spray of microdroplets suspending at least the particles is established forward of the spray dispenser end by creating a nonuniform electrical field between the spray dispenser end and an electrode electrically isolated therefrom. The particles are coated with at least a portion of the coating material as the microdroplet evaporates. For example, the suspension may include biological material particles.Type: GrantFiled: October 4, 2007Date of Patent: July 5, 2011Assignee: Regents of the University of MinnesotaInventors: David Y. H. Pui, Da-Ren Chen

Patent number: 7906182Abstract: A method of forming a smooth thin film on a substrate within a short deposition time, the method comprising introducing ionic substances (salts, acids, bases) to a polymeric solution to be sprayed. These ions attach to the polymer strands in solution, increasing their charge to mass ratio. This results in mutual repulsion of the strands during the spray process and produces a smooth film, even at relatively high polymeric solution concentrations. A side effect of this process is the introduction of impurities (the added ions) to the polymer thin film. The proper choice of ionic compound allows a dissolution step to be used to “clean” the polymer film after deposition, using the solubility characteristics of the thin film versus the ionic compound.Type: GrantFiled: January 14, 2009Date of Patent: March 15, 2011Assignee: University of South FloridaInventor: Rudiger Schlaf
