This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.

This disclosure relates to medical tubing installation detection. In certain aspects, a method is performed by a data processing apparatus. The method includes detecting that a tube is incorrectly installed on a drug delivery device by providing an instruction for a motor of the drug delivery device to pump a drug and receiving, after a period of time has passed since providing the instruction for the motor of the drug delivery device to pump the drug, a signal from a fluid detector connected to the tube, the signal indicating an absence of fluid in the tube.

Apparatus for manufacturing or processing articles includes smart microcontroller boards which cooperate with sensors and a communication system to monitor and control manufacturing processes. Microcontroller boards disposed within a container create a microprocessor module which is secured to the apparatus for controlling the same responsive to information provided to them. Sensors are provided for monitoring operation of the apparatus and providing such information to the microcontroller boards. The communication system provides for communication between the sensors and the microcontroller boards, among microcontroller boards and between the microcontroller boards and other portions of the apparatus which are to be subjected to responsive control. In a preferred embodiment, the microcontroller boards are positioned within a container which is secured in a recess in the apparatus and has an overlying material covering the boards. A plurality of microcontroller modules may be employed in a system. Associated methods are disclosed.

Apparatus for progressively manufacturing fabricated or semi-fabricated articles, such as a rotor or stator assembly, includes a punch press and a progressive stamping die for creating the assemblies from sheet stock moving therebetween. A microcontroller board or network, including a plurality of microcontroller boards, is secured to the die for controlling operation of the apparatus responsive to information provided to them. Sensors are provided for monitoring operation of the apparatus and providing such information to the microcontroller boards. The communication system provides for communication between the sensors and the logic chips, among the logic chips and among the microcontroller boards and between the microcontroller boards and other portions of the apparatus which are to be subjected to responsive control. In a preferred embodiment, the microcontroller boards are positioned within a container which is secured in a recess in the progressive die and has an overlying material, such as an epoxy, covering all of the logic chips such that efforts to remove the material will at least partially destroy the chips. The die and microcontroller boards may be secured to and removed from the press as a unit. An associated method is disclosed.
