Abstract: Systems and methods are directed to allocating unused or otherwise under-utilized computing resources of autonomous vehicles. In one example, a computer-implemented method obtaining, by a computing system, data describing a computational status of each autonomous vehicle of one or more autonomous vehicles describing a current or forecasted computational load. The method includes determining, by the computing system, an amount of excess computational capacity of each autonomous vehicle of the one or more autonomous vehicles, the amount of excess computational capacity for each autonomous vehicle of the one or more autonomous vehicles based at least in part on the computational status of the autonomous vehicle and a total computational capacity of the autonomous vehicle. The method includes allocating, by the computing system, at least a portion of the amount of excess computational capacity of each autonomous vehicle to processing operations associated with participation in a distributed ledger.

Abstract: This disclosure relates to preventing over-delivery of a drug and related systems and methods. In certain aspects, a method is performed by a data processing apparatus. The method includes receiving, from a drug delivery device, information pertaining to a desired amount of fluid to be delivered by the drug delivery device and receiving information pertaining to a delivered amount of a fluid that has been delivered by the drug delivery device. The method also includes determining that the delivered amount satisfies a predetermined threshold amount and in response to the determination, detecting whether an initial amount of fluid provided to the drug delivery device corresponds to the desired amount of fluid to be delivered.

Abstract: 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.

Abstract: This disclosure relates to vial spiking assemblies and related methods. In certain aspects, the vial spiking assemblies include a vial adapter having a base, a spike extending from a central region of the base, and a sidewall extending from the base and surrounding the spike. The base and the sidewalls partially, define a cavity that is configured to receive at least a portion of the vial. The assemblies also include a spike cover that is removably attached to the spike and that includes a material configured to indicate when the material is contacted with liquid.

Abstract: 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.
