Abstract: An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers (percussion caps). An adapter connects the firing actuator to shock tube and channels the ignition force into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and the detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive wave into the adapter, which channels the wave into the shock tube and ignites the shock tube. The explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach structures or other applications.

Abstract: In some examples, a controller may include a processing resource and a memory resource storing non-transitory machine-readable instructions that are executed to cause the processing resource to direct a clock signal of an imaging device to a fill port via a detection circuit of the imaging device, determine based on a state of a switch included in the detection circuit whether the fill port is open or closed, determine based on the state of the switch indicating the fill port is closed a status of the fill port, and in response to the status of the fill port being closed, determine based on a voltage of the clock signal whether the fill port is connected to a colorant container.

Abstract: A replaceable printing subassembly is disclosed. The replaceable printing subassembly includes a printbar. A fluid delivery system including a pump is fluidically coupled to the printbar. A frame is coupled to the fluid delivery system. The replaceable printing subassembly also includes a lift mechanism having an actuator to selectively move the printbar with respect to the frame.
