Patent number: 11891194Abstract: Systems and methods related to redundant battery management systems (BMS) may include an on-battery BMS, and one or more off-battery, off-vehicle, and/or remote BMS. The one or more remote BMS may receive data associated with parameters of a battery, and may process the received data using various models, algorithms, or estimators to determine a battery state. The battery state determined by the remote BMS may then be used to corroborate or support a battery state determined by the on-battery BMS, thereby ensuring safe, reliable, and efficient operations of systems, machines, or devices utilizing batteries as power sources.Type: GrantFiled: May 1, 2020Date of Patent: February 6, 2024Assignee: Amazon Technologies, Inc.Inventors: Hillel Moshe Saul Baderman, Ben Martin Schweitzer, Joseph Rutland, Sergey Andreev

Publication number: 20230010120Abstract: Devices and methods for generating energy (e.g., electrical energy) from wind. A preferred form is directed to a wind charger that creates energy from wind to be directed to a source needing the created energy, e.g., one or more batteries. The batteries can be used to power any device including but not limited to devices in homes needing energy and/or devices that transport one or more persons over land, in the air or over water. Preferably, a mounting assembly optimally positions one or more elements generating electrical energy from wind relative to direction of wind to maximize the electrical energy generated by wind.Type: ApplicationFiled: June 30, 2022Publication date: January 12, 2023Inventor: ROBERT MARTIN SCHWEITZER

Patent number: 11175346Abstract: Systems and methods to measure states of charge of a battery may include an ultrasonic sensor and a control system. For example, the control system may instruct the ultrasonic sensor to emit ultrasonic waves toward a battery, and may instruct the ultrasonic sensor to receive echoes of the emitted ultrasonic waves reflected back from the battery. In addition, the control system may process data associated with the emitted waves and received echoes, including properties associated with the waves and echoes, such as a time of flight, frequency, amplitude, wavelength, phase, duration, or others. Based on the properties of the received echoes, and by comparison with expected properties, various physical, mechanical, chemical, and/or material characteristics of the battery may be determined, based on which a state of charge and/or a state of health of the battery may further be determined.Type: GrantFiled: May 20, 2019Date of Patent: November 16, 2021Assignee: Amazon Technologies, Inc.Inventors: Ben Martin Schweitzer, Jean-Guillaume Dominique Durand

Patent number: 10809309Abstract: Systems and corresponding methods for monitoring of a state of charge or a state of health of a battery are described. For example, the battery monitoring system may include strain gauges to measure dimensions or changes in dimension of cells of the battery, and may determine states of charge of the cells based on dimensional changes over time, e.g., based on data from strain gauges. The dimensional changes may also be corrected for dimensional changes due to thermal strain. In addition, states of health of individual cells of the battery may be determined by comparing the dimensional changes of each of the cells over time. Further, the data from strain gauges may be received at various frequencies, e.g., based on an expected operational duration of the battery and/or based on a current state of charge or state of health.Type: GrantFiled: July 11, 2019Date of Patent: October 20, 2020Assignee: Amazon Technologies, Inc.Inventors: Chengwu Cui, Benjamin Martin Schweitzer

Patent number: 8302762Abstract: The invention relates to a device for transporting flat products having at least one feeder feeding the flat products in a first transport direction, and having at least two conveying units for forwarding the flat products in a second transport direction. The conveying units are configured symmetrically and in each case have a plurality of guiding elements which can be set against the flat sides of the products. It is possible for the flat products to be received between in each case two adjacent guiding-element pairs and to be gripped by them and, as a result, to be transported upright in the second transport direction. During the movement in the second transport direction, the guiding elements are moved gradually out of holding engagement with the flat products.Type: GrantFiled: June 22, 2011Date of Patent: November 6, 2012Assignee: Palamides GmbHInventors: Cristovao Mesquita, Martin Schweitzer
