Patent number: 11791503Abstract: A method of managing a battery of a wireless sensor or other battery-powered remote wireless device includes pre-characterizing the device's energy usage during its various activities and modes, placing the device in operation, opportunistically gathering device operational data obtained for purposes other than battery management, and estimating a status of the battery according to an analysis of the operational data in light of the pre-characterized information. The method further includes taking a battery management action according to the estimated battery status, such as recharging or replacing the battery when it is nearly exhausted, and/or modifying the operation of the device so as to extend the battery lifetime, for example by reducing or increasing the frequency of data transmissions, measurements, calculations, and/or other dynamic current events. The status estimate can further be in light of measurements provided by a simple current measuring circuit included in the device.Type: GrantFiled: July 20, 2021Date of Patent: October 17, 2023Assignee: Flowserve Pte. Ltd.Inventor: Stewart D. Reed

Publication number: 20130037260Abstract: Systems and methods for using power cycle events to cause a downhole tool to change its operational state and/or transmit a data stream to the downhole tool. In one embodiment, a tool such as a gauge for an ESP is positioned downhole in a well and is configured to receive power from a control unit at the surface of the well. The control unit power cycles the downhole tool to communicate a need to modify the operational state of the tool. The tool may include a non-volatile memory to store an indicator of the tool's current operational state. When the tool is power cycled, the operational state is modified and the indicator is updated. The power cycling may cause the tool to increment through available operational states, or the timing of the power cycles may convey parameters or other operating information to the downhole tool.Type: ApplicationFiled: August 10, 2011Publication date: February 14, 2013Inventor: Stewart D. Reed

Publication number: 20120037354Abstract: Systems and methods for reliably communicating data at high data rates between surface and downhole equipment over a power cable by multiplexing data, modulating the data onto orthogonal carrier frequencies, communicating the modulated carrier signals over the power cable, recovering of the modulated signals, and demodulating the data stream from the recovered signal. One embodiment comprises a system that includes surface equipment connected by a power cable to an ESP system that has a gauge package connected to it. The gauge package uses a high-temperature DSP to perform the data processing associated with OFDM communications.Type: ApplicationFiled: August 12, 2010Publication date: February 16, 2012Inventors: Robert H. McCoy, Gordon L. Besser, Stewart D. Reed, Dustin B. Campbell, Dick L. Knox

Patent number: 6755473Abstract: A chair, or other office furniture device, includes a first and second support member. The first support member has a longitudinal extent and a fluid passageway formed within at least a portion thereof. A first piston, having a first and second end, is moveably disposed in the fluid passageway. The second support member is coupled to the first end of the first piston. A fluid supply is disposed in the fluid passageway and communicates with the second end of the first piston. A pressure is applied to the fluid supply. A fluid flow controller controls a flow of the fluid supply and is operable between at least an open and closed position, wherein the fluid supply is allowed to flow when the controller is in the open position and wherein the fluid supply is not allowed to flow when the controller is in the closed position.Type: GrantFiled: November 21, 2001Date of Patent: June 29, 2004Assignee: Herman Miller, Inc.Inventors: Stewart D. Reed, James M. Schaddelee, George A. Miles, Steven B. Panse

Patent number: 6702200Abstract: A nozzle attitude controller for use in connection with a farming apparatus for precision farming, the apparatus comprising an applicator vehicle, a boom supported by and extending across the rear of the vehicle, a manifold rotatably supported by the boom, a plurality of nozzles disposed from the manifold and oriented in a direction opposite to the direction of movement of the vehicle, but disposed at an angle with respect to the horizontal, the attitude controller including a linear actuator operated by a stepper motor and a radar sensor which connects to the stepper motor and which measures the speed of the vehicle such that pulses from the radar sensor to the stepper motor moves the linear actuator to change the angle of the nozzle so that the horizontal component of its velocity is equal and opposite to the speed of the vehicle.Type: GrantFiled: July 24, 2001Date of Patent: March 9, 2004Assignee: The Board of Regents for Oklahoma State UniversityInventors: John B. Solie, Marvin L. Stone, Stewart D. Reed

Patent number: 5180089Abstract: A universal connector mechanically couples any one or more of a variety of accessories to a vehicle. The universal connector comprises a first mounting member, which can extend along a section of a vehicle such as a door panel, instrument panel or the like and can be mounted in recessed relationship to the vehicle. The universal connector also includes a second mounting member associated with each accessory and shaped to lockably and removably engage the first mounting member. In a preferred embodiment of the invention, at least one of the mounting members is made of a resilient material to allow a snap-fit interconnection of the two members.Type: GrantFiled: December 17, 1991Date of Patent: January 19, 1993Assignee: Prince CorporationInventors: Michael J.

Patent number: 4446586Abstract: An arrangement for bathing invalids, or others with impaired ambulatory ability, comprises an enclosure having a bathtub with upstanding walls which form a stall. The bathtub includes a seat having an anatomical contour and a lateral opening adjacent the seat to permit invalid ingress and egress. A door with a generally wedge-shaped contour mates with and selectively closes the bathtub opening, and includes a seal compressed between the opening lip and the door to form a seal which is sufficiently leakproof to permit immersal bathing of a seated invalid. The door is slideably mounted on a hingeless track assembly, which vertically translates the door into the closed position and pivots the door as it is raised into a horizontal, overhead storage position. Shower heads are mounted on the walls of the stall to provide both shower and immersal bathing for hygiene and therapy.Type: GrantFiled: May 20, 1982Date of Patent: May 8, 1984Assignee: SilchorInventors: Stewart D. Reed, Arthur A. Sills, John H. Kraft, Raymond T. Houle, Michael A. Redwine, Fredrick A. Kilborn

Patent number: 4365367Abstract: A bathing apparatus for invalids and the like, comprises a bathtub having a lateral opening in one side thereof for invalid ingress and egress, a door selectively closing the bathtub opening, and a seal positioned between the door and the bathtub. The door is slidably mounted in a pair of tracks disposed on opposite sides of the door for vertically translating the door between open and closed positions. A counterbalance for the door comprises a pair of spools mounted on opposite ends of a spring loaded axle, and a pair of flexible lines having one pair of ends wrapped around the spools, and the opposite ends attached to the door, whereby downward translation of the door tenses the spring and counterbalances the weight of the door. A lock for the door comprises a foot operated lever arrangement, which engages both sides of the door and positively pulls the same downwardly against the seal into the closed position.Type: GrantFiled: September 15, 1980Date of Patent: December 28, 1982Assignee: SilchorInventors: Raymond T. Houle, Michael A. Redwine, Fredrick A. Kilbourn, Stewart D. Reed, Arthur A. Sills, John H. Kraft
