Abstract: A device for attachment to a linear force transmission medium such as a wire or rod includes a flexure body having axially aligned tubular extensions on opposite ends that can receive and be crimped to the medium to create a continuous path for tensile force transmission. The flexure carries strain gages on top and bottom planar surface portions that are connected into a bridge circuit that responds to stress in the flexure body. Leads are protected against disconnection from solder pads by wrapping the leads and a carrier for them around the exterior circumferential surface of a jacket that fits on and around the flexure body. An FPC plug embodiment is disclosed.

Abstract: Computational methods and systems for detecting and troubleshooting anomalous behavior in distributed applications executing in a distributed computing system are described herein. Methods and systems discover nodes comprising the application. Anomaly detection monitors the metrics associated with the nodes for anomalous behavior in order to identify an approximate point in time when anomalous behavior begins to adversely impact performance of the application. Anomaly detection also monitors logs messages associated with the nodes to detect anomalous behavior recorded in the log messages. When anomalous behavior is detected in either the metrics and/or the log messages an alert identifying the anomalous behavior is generated. Troubleshooting guides an administrator and/or application owner to investigate the root cause of the anomalous behavior. Appropriate remedial measures may be determined based on the root cause and automatically or manually executed to correct the problem.

Abstract: Systems and methods of the present disclosure enable reversible blockchain operations. An operation-reverse operation pair specifies an operation for exchange of a first token for a second token, and a reverse operation for return of the second token for the first token upon at least one condition being satisfied. A self-executing software container (SESC) executes the operation-reverse operation pair according to the condition by detecting a transfer of the first token into a first segregated data structure, and a transfer of the second token from a second token storage to a first token storage. The SESC initiates a transfer of the first token from the first segregated data structure to a second segregated data structure in response to the transfer of the second token. Upon detecting a reverse operation matching the condition, the SESC initiates a transfer of the first token back to the first segregated data structure.

Abstract: A cantilever force sensor with relatively lower On-Force is disclosed, which comprises a top stack, a bottom stack, and a spacer. The first spacer is configured between the top stack and the bottom stack and configured in a first side of the force sensor. A second side, opposite to the first side, of the top stack, is cantilevered from the bottom stack. When the force sensor is depressed from the top side, the second side of the top stack moves down using the first spacer as a fulcrum. Since the cantilevered side can be easily depressed down so that the On-Force for the force sensor is reduced and hence a force sensor with a relatively higher sensitivity is created.
