Patent number: 10589108Abstract: A system for providing energy to a bio-implantable medical device includes an acoustic energy delivery device and a bio-implantable electroacoustical energy converter. The acoustic energy delivery device generates acoustic energy with a multi-dimensional array of transmitting electroacoustical transducers. The acoustic energy is received by one or more receiving electroacoustical transducers in the bio-implantable electroacoustical energy converter. The receiving electroacoustical transducers convert the acoustic energy to electrical energy to power the bio-implantable medical device directly or indirectly. An external alignment system provides lateral and/or angular positioning of an ultrasound energy transmitter over an ultrasound energy receiver. The acoustic energy transmitter alignment system comprises either or both x-y-z plus angular positioning components, and/or a substantially multi-dimensional array of transmitters plus position sensors in both the transmitter and receiver units.Type: GrantFiled: February 27, 2019Date of Patent: March 17, 2020Assignee: Piezo Energy Technologies LLCInventors: Leon J.

Patent number: 9155310Abstract: Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing.Type: GrantFiled: November 25, 2013Date of Patent: October 13, 2015Assignee: Agienic, Inc.Inventors: Anoop Agrawal, Nicholas R.
