A detonator includes a substrate, a controller mounted to the substrate, and a sensor coupled to the controller to measure a temperature, pressure, acceleration or other environmental parameter of the detonator. The controller is configured to transmit the measured environmental parameter from the detonator to a remote master controller, execute an action in response to a value of the measured environmental parameter, and/or prevent or modify at least one detonator function in response to the value of the measured environmental parameter.

Integrated detonator sensors

The present invention provides in a stack mold comprising a center mold part, first and second outside mold parts moveable at both sides of the center mold part, a rack and pinion gear arrangement to move the outside mold parts. The rack and pinion gear arrangement comprises a plurality of pinion gears located at the center mold part and including a drive gear and first and second follower gears driven off the drive gear. Also provided are first and second free ended racks extending in opposite directions from the first and second outside mold parts respectively in engagement with the first and second follower gears. These follower gears reach above and below the drive gear and the first follower gear is offset to the side of the drive gear opposite that to which the free end of the first rack extends while the second follower gear is offset to the side of the drive gear opposite that to which the free end of the second rack extends.
