Patent number: 9686051Abstract: Systems, methods, and computer readable media for providing lossless transmission of sensor data in a wireless network are provided. In some aspects, a method for transmitting data in a wireless sensor network includes collecting data at a sensor node, attaching a timestamp to the data, buffering the data and the timestamp to a memory device and retransmitting the collected data where the sensor node fails to receive an acknowledgement message from the base station after the data transmission. In some aspects, a system can include a plurality of wireless sensor nodes having synchronized clocks and a base station. Collected sensor data can be associated with a timestamp via the clock prior to transmitting the data to the base station. The data can be buffered at a memory device and retransmitted therefrom to provide lossless data transmission.Type: GrantFiled: December 27, 2013Date of Patent: June 20, 2017Assignee: LORD CorporationInventors: Stephen J.

Patent number: 8154177Abstract: A device for harvesting an external source of energy includes an electricity generating device, a flexure, and a first stop. Displacement of the flexure is limited by the first stop.

Patent number: 8134282Abstract: A device for harvesting an external source of energy includes an electricity generating device, a flexure, and a restoring spring. The electricity generating device generates electricity based on movement of the flexure. The flexure has a first stable position. When disregarding presence of the restoring spring the flexure also has a second stable position different from the first stable position. The restoring spring is positioned so when the flexure snaps from the first stable position toward the second stable position the restoring spring provides a restoring spring force to restore the flexure toward the first stable position. Substantially greater force is needed to snap the flexure from the first stable position toward the second stable position to overcome the restoring spring force than is required to snap the flexure from the second stable position toward the first stable position.Type: GrantFiled: September 1, 2010Date of Patent: March 13, 2012Assignee: Microstrain, Inc.Inventors: David L. Churchill, Steven W. Arms, Michael J. Hamel, James Marc Leas
