Examples herein relate to checkpoint replication and copying of updated checkpoint data. For example, a memory controller coupled to a memory can receive a write request with an associated address to write or update checkpoint data and track updates to checkpoint data based on at least two levels of memory region sizes. A first level is associated with a larger memory region size than a memory region size associated with the second level. In some examples, the first level is a cache-line memory region size and the second level is a page memory region size. Updates to the checkpoint data can be tracked at the second level unless an update was previously tracked at the first level. Reduced amounts of updated checkpoint data can be transmitted during a checkpoint replication by using multiple region size trackers.

A dual latching microvalve is capable of a metastable state, wherein a one or more complete flow paths are open, before switching to another state that allows only an inlet or outlet valve to be open at any time on any fluid path. One valve mechanism uses a cam to alternately open and close two valves, with an external force applying pressure to move one valve arm onto a resting position on the cam, thereby opening the closed valve and provided an uninterrupted flow path through the dual latching microvalve. The metastable state provides, for example, a means to prime the pump before operation, such as pumping of insulin into a patient. When released from the metastable state, the dual latching microvalve operates in a fashion whereby opening of both valves simultaneously is prevented, thereby protecting the patient from injury.

A method for optimizing climate control in an autonomous vehicle. The method includes receiving a ride request for an autonomous vehicle from a customer. A desired temperature for an interior of the autonomous vehicle may be determined based on the ride request. The current temperature of the vehicle interior may then be adjusted such that the current temperature substantially matches the desired temperature when the autonomous vehicle reaches the customer. The temperature of the vehicle interior may be allowed to deviate from the desired temperature, within a pre-determined temperature deviation range, when the autonomous vehicle is unoccupied. A corresponding system and computer program product are also disclosed and claimed herein.

Presented are joint active thermal management (JATM) systems with heat exchanger storage of surplus refrigerant, methods for making/operating such systems, and vehicles equipped with such systems. A JATM system includes a coolant loop that fluidly connects to a vehicle battery system for pumping thereto coolant, an oil loop thermally coupled to the coolant loop and fluidly connected to a vehicle powertrain system for pumping thereto oil, and a refrigerant loop thermally coupled to the coolant loop and operable to circulate refrigerant for heating/cooling a passenger compartment. An electronic controller determines if a current amount of refrigerant in the refrigerant loop exceeds a calibrated threshold for the current operating mode of the JATM system. If so, the controller determines if one of the refrigerant loop's heat exchangers is available to store excess refrigerant. If the heat exchanger is available, the refrigerant loop stores excess refrigerant in the available refrigerant heat exchanger.
