Abstract: A modular force/torque sensor system is disclosed. In various embodiments, a sensor interface device includes a first communication interface configured to receive an analog output associated with a sensor located remotely from the sensor acquisition device; a processor configured to use the analog output associated with the sensor to generate a sequence of discrete values derived from the analog output associated with the sensor; and a second communication interface coupled to the processor and configured to send at least a subset of the sequence of discrete values derived from the analog output associated with the sensor to a control module.

Abstract: In an example, a method comprises fabricating a first validation device for association with a first replaceable print apparatus component. The device may be to form part of circuitry arranged on the first replaceable print apparatus component, and may provide an associated electrically detectable characteristic which varies with the position of at least part of the first validation device. The electrically detectable characteristic may be measured and data indicative of the characteristic may be stored in a first memory. The first replaceable print apparatus component comprising the first device and the first memory may be assembled.

Abstract: A system for in-situ oil shale recovery, which includes a well casing having a leak-tight shaft liner, a gas evacuating system for removing gases from the well casing, and a solar collection system for directing a source of radiant energy through the well casing to a strata of oil shale.
