Patent number: 11911128Abstract: A mote includes an optical receiver that wirelessly receives a power and data signal in form of NIR light energy within a patient and converts the NIR light energy to an electrical signal having a supply voltage. A control module supplies the supply voltage to power devices of the mote. A clock generation circuit locks onto a target clock frequency based on the power and data signal and generates clock signals. A data recovery circuit sets parameters of one of the devices based on the power and data signal and a first clock signal. An amplifier amplifies a neuron signal detected via an electrode inserted in tissue of the patient. A chip identifier module, based on a second clock signal, generates a recorded data signal based on a mote chip identifier and the neuron signal. A driver transmits the recorded data signal via a LED or a RF transmitter.Type: GrantFiled: February 11, 2021Date of Patent: February 27, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: David T. Blaauw, Jamie Phillips, Cynthia Anne Chestek, Taekwang Jang, Hun-Seok Kim, Dennis Sylvester, Jongyup Lim, Eunseong Moon, Michael Barrow, Samuel Nason, Julianna Richie, Paras Patel

Patent number: 9684293Abstract: A relief valve monitoring system and method can monitor the pressure in a pressure vessel in an ammonia refrigeration system and warn of an impending overpressure condition and a possible subsequent ammonia release event through a pressure relief valve. If a pressure relief valve opens, the relief valve monitoring system and method can identify the relief valve that has opened by monitoring the downstream pressure of the relief valve, accurately determine the amount of ammonia refrigerant that has been released into a common collection header, and purge the common collection header of residual ammonia after the ammonia release event has ended.Type: GrantFiled: December 1, 2014Date of Patent: June 20, 2017Assignee: BRT, LLCInventors: William E. Barrow, Michael A. Barrow, Elizabeth Barrow Moore

Patent number: 9332605Abstract: A lighting system includes a switch configured so that when the switch is in a first state, current from a supply flows to a light emitter, and when the switch is in a second state, current from the supply flows through the switch bypassing the light emitter. A capacitor in parallel with the light emitter provides current to the light emitter sufficient to cause the light emitter to emit light when the switch is in the second state.Type: GrantFiled: December 9, 2013Date of Patent: May 3, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Irwin Rudolph Nederbragt, Steven Michael Barrow, Yan Yin, Craig Steven Cambier

Patent number: 8847372Abstract: An exposed die overmolded flip chip package includes a substrate. A die is flip chip mounted to an upper surface of the substrate. The package further includes a mold cap filling a space between an active surface of the die and the upper surface of the substrate. The mold cap includes a principal surface, sidewalls extending from the upper surface of the substrate to the principal surface, an annular surface coplanar with the inactive surface of the die and extending outward from a peripheral edge of the inactive surface of the die, and protruding surfaces extending between the principal surface and the annular surface. The mold cap does not cover the inactive surface of the die such that heat transfer from the die to the ambient environment is maximized and the package thickness is minimized.Type: GrantFiled: August 21, 2013Date of Patent: September 30, 2014Inventors: Robert Francis Darveaux, Michael Barrow, Miguel Angel Jimarez, Jae Dong Kim, Dae Keun Park, Ki Wook Lee, Ju Hoon Yoon

Patent number: 7543377Abstract: A ball grid array (BGA) integrated circuit package which has an outer two-dimensional array of solder balls and a center two-dimensional array of solder balls located on a bottom surface of a package substrate. The solder balls are typically reflowed to mount the package to a printed circuit board. Mounted to an opposite surface of the substrate is an integrated circuit that is electrically coupled to the solder balls by internal routing within the package. The outer array of solder balls are located the dimensional profile of the integrated circuit to reduce solder stresses induced by the differential thermal expansion between the integrated circuit and the substrate. The center solder balls are typically routed directly to ground and power pads of the package to provide a direct thermal and electrical path from the integrated circuit to the printed circuit board.Type: GrantFiled: October 29, 2007Date of Patent: June 9, 2009Assignee: Intel CorporationInventor: Michael Barrow
