Patent number: 10434329Abstract: A power transmitter is provided that can include a microwave cavity resonant at a desired operating frequency, a hexagonal mesh top to leak evanescent fields out of the cavity, and a plurality of orthogonal monopole feeds with 90 degrees phase differences creating circularly polarized waves. The power transmitter can be configured to transmit energy to a wireless device implanted in an animal passing through the evanescent fields. Implantable devices are also described which can receive wireless energy from the power transmitter and stimulate the animals (e.g., optogenetic or electrical stimulation).Type: GrantFiled: March 25, 2015Date of Patent: October 8, 2019Assignee: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventors: Ada Shuk Yan Poon, John S. Y. Ho, Yuji Tanabe, Alexander J. Yeh, Kate L. Montgomery, Logan Grosenick, Emily A. Ferenczi, Vivien Tsao, Shrivats Mohan Iyer, Scott Lee Delp, Karl Deisseroth

Publication number: 20190247667Abstract: Implantable devices and/or sensors can be wirelessly powered by controlling and propapting electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.Type: ApplicationFiled: April 23, 2019Publication date: August 15, 2019Inventors: Ada Shuk Yan Poon, Alexander Jueshyan Yeh, Yuji Tanabe, John Ho, Sanghoek Kim

Patent number: 10379059Abstract: A defect of a film is accurately inspected. A film inspection device includes: a light-receiving device generating a signal by receiving light which returns via a film after having been applied to the film, the signal being for detecting a defect included in the film; and a reflecting roller carrying the film while supporting the film from a side opposite to the light-receiving device in a field of view of the light-receiving device.Type: GrantFiled: July 14, 2016Date of Patent: August 13, 2019Assignee: SUMITOMO CHEMICAL COMPANY, LIMITEDInventors: Genjiro Nishikata, Yuji Tanabe, Tatsuya Kataoka

Patent number: 10079438Abstract: A radio-frequency power receiving device has RF antennas connected to multiple controllable rectifying circuits to produce corresponding DC signals which are combined in a controllable switching network to produce a combined DC output. A control unit determines an amplitude control signal that controls each rectifying circuit and also determines switch control signals that control a switching network. The switching network controllably combines the direct-current signals to combine the multiple corresponding direct-current signals in series, in parallel, or in a combination of series and parallel.Type: GrantFiled: September 21, 2016Date of Patent: September 18, 2018Assignee: NVoLogic IncInventors: Yuji Tanabe, Ada Shuk Yan Poon, Siu-Weng Simon Wong
