Patent number: 10749264Abstract: A cavity-backed slot antenna is disclosed that includes a stripline. The stripline includes a conductive strip between two ground planes separated by a dielectric. The conductive strip feeds the cavity-backed slot antenna. The stripline also includes a first segment and a second segment. The first segment has a first characteristic impedance. The second segment is proximate the cavity-backed antenna and has a second characteristic impedance different than the first characteristic impedance. The second characteristic impedance provides impedance for matching a load impedance of the cavity-backed slot antenna.Type: GrantFiled: October 13, 2017Date of Patent: August 18, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Nahal Niakan, Sean Russell Mercer, Toby James Morris

Publication number: 20190253095Abstract: A radiofrequency (RF) power regulator includes a forward RF power detection circuit to detect forward RF power supplied by an RF transmitter circuit to an RF transmitting antenna. An RF power sampler is coupled to the forward RF power detector circuit and provides RF power samples of the supplied forward RF power. Multiple filters are coupled to receive the RF power samples. Each filter differently filters the received forward power samples to apply a different average power period. Each filter activates an RF power adjustment trigger signal while a time-averaged forward RF power supplied to the RF transmitting antenna satisfies a forward RF power adjustment condition for the average power period of the filter. Forward RF power adjustment logic is coupled to filters and operable to adjust the forward RF power supplied by the RF transmitter circuit to the RF transmitting antenna based on the RF power adjustment trigger signal.Type: ApplicationFiled: January 8, 2019Publication date: August 15, 2019Inventors: Sean Russell Mercer, Charbel Khawand, Wenkai Zhong

Publication number: 20190112614Abstract: A method for deleting a region of DNA in a plant. In some embodiments, the method comprises transforming a plant with a nucleic acid molecule, wherein the nucleic acid molecule encodes one or more zinc finger nuclease(s) (ZFNs) operably linked to one or more tissue-specific promoter(s), e.g., a pollen-specific promoter. Methods include excising native genes in a plant. Accordingly, in some embodiments, ZFNs are engineered that recognize sequences that flank native plant genes. In further embodiments, ZFNs are expressed under the control of developmental stage-specific promoters, such that, for example, nucleic acid sequences are specifically excised in plants during relatively late stages of development. Nucleic acid molecules useful for carrying out disclosed methods and plants produced by the methods are included.Type: ApplicationFiled: December 18, 2018Publication date: April 18, 2019Inventors: Sean Russell, Joseph F.

Publication number: 20180375748Abstract: A first encapsulation protocol processing component (EPPC) at a particular device of a virtualized computing service establishes a network packet tracking session with a second EPPC at another device. The first EPPC tags at least some encapsulation packets (which contain baseline packets generated at or directed to guest virtual machines) sent to the second EPPC as tracked packets. The first EPPC obtains network metrics corresponding to the tracked packets of the session from the second EPPC, prepares network health updates based on the metrics, and send the updates to a network health management service associated with the virtualized computing service.Type: ApplicationFiled: August 6, 2018Publication date: December 27, 2018Applicant: Amazon Technologies, Inc.Inventor: David Sean Russell
