Abstract: A downhole energy harvesting system includes a housing subjected to periodic oscillations. An energy harvesting device is on, in, or otherwise connected to the housing and positioned to generate electricity based on the periodic oscillations. The energy harvesting device is coupled to at least one of a powered component or an energy storage device in order to use or store the harvested energy.

Abstract: A battery which has electrodes and electrolyte inside a rigid outer container is fitted with a sensor device in the form of a strap at the exterior of the container. The strap has a strain gauge secured to the strap to observe strain on stretching the strap. The strap incorporates a tightening mechanism for reducing a length of the strap. After the strap has been put in place at the exterior of the container, the tightening mechanism is used to pull the strap taut with a length of the strap pressing against the exterior of the container. The strain gauge may be used to monitor expansion of the outer container during charging and thus indicate state of charge or to monitor expansion during the working life of the battery and this indicates its state of health. The sensor devices may be used for a large number of batteries storing electricity on grid scale, with electronics attached to each strap communicating wirelessly with a battery management system.

Abstract: A control system for a saw blade used to cut slots in carbon anodes used in aluminum processing includes an instrument package installed on the saw blade. The instrument package includes one or more sensors used to measure one or more operating characteristics. If the operating characteristics are outside of a threshold operating characteristic. then one or more operating parameters of the saw blade can be adjusted. Example adjustments may be made to the rotational speed or depth of cut of the saw blade. or repair or replacement of cutting elements or the saw blade.

Abstract: A bit to detect drill bit metamorphism (DBM) may include a bit head. A bit to detect DBM may include at least one cutting element connected to the bit head. A bit to detect DBM may include a temperature sensor on or in the at least one cutting element. A bit to detect DBM may include an electronics module in communication with the temperature sensor. A bit to detect DBM may include a wiring conduit from the at least one cutting element and through at least a portion of the bit head to the electronics module.

Abstract: A downhole measurement module includes a microcontroller having a plurality of inputs and a sensor connected to a first input of the plurality of inputs. A switch is connected to a second input of the plurality of inputs. The microcontroller implements a measurement program to receive measurements from the sensor, the measurement program being based on a setting of the switch.
