Patent number: 11585692Abstract: A sensor system includes a sensor network comprising at least one optical fiber having one or more optical sensors. At least one of the optical sensors is arranged to sense vibration of an electrical device and to produce a time variation in light output in response to the vibration. A detector generates an electrical time domain signal in response to the time variation in light output. An analyzer acquires a snapshot frequency component signal which comprises one or more time varying signals of frequency components of the time domain signal over a data acquisition time period. The analyzer detects a condition of the electrical device based on the snapshot frequency component signal.Type: GrantFiled: January 27, 2020Date of Patent: February 21, 2023Assignees: Palo Alto Research Center Incorporated, General Electric CompanyInventors: Peter Kiesel, Ajay Raghavan, Todd Karin, Qiushu Chen, Malcolm G.

Patent number: 11486919Abstract: An approach to detecting partial discharge events involves retrofitting an electrical system to include a capacitive sensor configured to capacitively sense partial discharge events of a component of the electrical system. The capacitive sensor has a first electrical conductor that forms a first terminal of the capacitive sensor, a second electrical conductor that forms a second terminal of the capacitive sensor, and a dielectric that separates the first electrical conductor and the second electrical conductor. The capacitive sensor generates an electrical sensor signal at an output of the capacitive sensor in response to the partial discharge event. The electrical sensor signal is converted to an optical signal and the optical signal is processed to detect an occurrence of the partial discharge event.Type: GrantFiled: October 24, 2019Date of Patent: November 1, 2022Assignees: Palo Alto Research Center Incorporated, General Electric Company, Consolidated Edison Company of New York, Inc.Inventors: Todd Karin, Peter Kiesel, Ajay Raghavan, Robert T.

Patent number: 6857569Abstract: A data storage card includes a glass substrate having first and second edges. A data storage surface region is located on the glass substrate between the first and second edges. The data surface region includes a magnetic storage medium having at least one layer of high density, high coercivity magnetic material for storing magnetic signals. The data storage card may include a relatively hard, abradeable protective coating formed on the magnetic material layer. The protective coating has a thickness between a maximum thickness which would materially attenuate magnetic signals passing between the magnetic material layer and a transducer of a read device, and a minimum thickness enabling said protective coating to be abraded by usage in an ambient natural atmosphere operating environment for removing therefrom a known quantity of the protective coating.Type: GrantFiled: September 15, 2000Date of Patent: February 22, 2005Assignee: UltraCard, Inc.Inventors: Malcolm G.

Patent number: 5107099Abstract: Apparatus and method wherein a credit card sized memory card having a magnetic storage medium thereon can be inserted into an operative position adjacent to a read/write head, and the card and head can be moved relative to each other to permit the head to read data from or to write data on the magnetic medium of the memory card. In a first embodiment, a disk form is provided like a hard disk but with a cut out portion or opening therein into which the memory card is insertable. The disk form can then be rotated so that the magnetic medium on the card can be moved past the read/write head movable radially of the central axis of the disk form. In another embodiment the memory card is movable into a fixed operative position adjacent to a read/write head and the head is movable radially as well as circumferentially arc so that the head and memory card are movable relative to each other in two degrees of freedom.Type: GrantFiled: April 24, 1989Date of Patent: April 21, 1992Inventor: Malcolm G.

Patent number: 4742410Abstract: An improved magnetic disk drive system including a rotatable disk, a shiftable carriage having a pair of read-write heads mounted by resilient arms thereon for coupled relationship with the disk, and a stepper motor for advancing and retracting the carriage and thereby the heads with respect to the disk. A locking mechanism is shiftably carried by a fixed base forming a part of the system, the mechanism including a locking member moveable between the resilient arms, whereby the arms are spread apart and the heads are moved away from the disk to prevent contact of the heads with the adjacent surfaces of the disk. The movement of the blocking member is a function of the movement of the carriage into its fully retracted position. Moreover, the member effectively locks the carriage against movement when the carriage is in the fully retracted position thereof.Type: GrantFiled: March 30, 1987Date of Patent: May 3, 1988Assignee: Josephine County Technology, Inc.Inventor: Malcolm G.
