Abstract: An injection device assembly including a housing, a syringe, a drive mechanism and a status sensing system and a module are described. The drive mechanism advances the syringe from a storage position to an injection position, and a plunger advances the syringe piston from an initial position to a final position. The status sensing system includes a light emitter that emits electromagnetic radiation into the housing transverse to the longitudinal axis, a light detector and a controller.

Abstract: An earth-boring tool includes primary and secondary cutting elements mounted to a tool body. The secondary cutting elements define a secondary cutting profile. The secondary cutting profile is recessed relative to the primary cutting profile, which is defined by the primary cutting elements.

Each secondary cutting element includes a flat surface oriented at an angle relative to a longitudinal axis thereof and extending between a front cutting face and a peripheral side surface thereof. The secondary cutting elements are oriented on the tool body such that a surface area of the flat surface thereof will engage the formation material at least substantially simultaneously when the primary cutting elements reach a worn condition.
