Systems and methods are described for operating an imaging system that includes an intra-oral imaging sensor and an electronic processor. The intra-oral imaging sensor includes a housing, an image sensing component at least partially housed within the housing, and a multi-dimensional sensor at least partially housed within the housing. The electronic processor is configured to receive an output of the multi-dimensional sensor indicative of movement of the intra-oral imaging sensor. The output is compared to predetermined movement criteria indicative of a type of movement and, in response to determining that the type of movement of the imaging sensor has occurred, the electronic processor alters the operation of the imaging system.

An accelerometer comprising a plurality of proof-masses moveable along a measurement axis; a respective spring rigidly attached to each proof-mass, configured to exert an elastic recall on the proof-mass in the measurement axis; and a fixed stop associated with each proof-mass, arranged to intercept the proof-mass when the acceleration in the measurement axis increases by a step. The proof-masses are suspended in series with respect to one another by springs in the measurement axis, the stops being arranged to successively intercept the respective proof-masses for increasing thresholds of acceleration.

Apparatuses, devices, and systems for selectively blocking an orifice of a container are disclosed herein. In one embodiment, a cap affixed to a container can comprise a spout comprising a spout orifice that can be selectively blocked and unblocked by a blocker. The blocker can be coupled to a blocker mover component that can be configured to move the blocker between blocked and unblocked positions in response to a blocker control signal generated by a cap control component. The cap control component can be configured to generate the blocker control signal based at least in part on input from a cap sensor configured to sense a condition of the container.
