Abstract: According to an example, a method for area occupancy information extraction may include receiving a signal from a sensor, and determining a number of occupants moving within a first area based on the signal. The method may further include determining when an occupant is moving and a direction of motion of the occupant based on the signal, and determining a most likely trajectory based on the direction of motion of the occupant. The method may also include controlling, by a processor, a service in the first area based on the determination of the number of occupants, the determination of when the occupant is moving and the direction of motion of the occupant, and/or the determination of the most likely trajectory.

Abstract: Apparatuses associated with liquid coolant supply are disclosed. One example apparatus is a computing cartridge which includes a first electronic device and a liquid-cooled cold plate. The computing cartridge also includes a first thermal couple between the first electronic device and the cold plate. The computing cartridge also includes an inlet fluid connector. The inlet fluid connector may supply a liquid coolant to the cold plate. The computing cartridge also includes an outlet fluid connector. The outlet fluid connector may facilitate return of the coolant from the cold plate.

Abstract: In some examples, a multiple chip module (MCM) includes a heat sink; a circuit board; a first chip secured to a first location on the circuit board; a first vapor chamber thermally coupled to the first chip to pass heat generated by the first chip to the heat sink; a second chip secured to a second location on the circuit board; and a second vapor chamber thermally coupled to the second chip to pass heat generated by the second chip to the heat sink. In some examples, a portion of the second vapor chamber is positioned between a portion of the first vapor chamber and the heat sink. In some examples, the first vapor chamber is substantially thermally insulated from the second vapor chamber.

Abstract: A device comprises a first layer of a die. The first layer comprises a microchannel. The microchannel is partially filled with a liquid and partially filled with air. The die also comprises a second layer. The second layer of the die seals a top of the microchannel of the first layer.

Abstract: Examples described herein include heat dissipating apparatuses with phase change material. In some examples, a heat dissipating apparatus comprises a wick structure to carry a cooling fluid to cool an electronic heat source, a vapor region to carry heated cooling fluid away from the wick structure, and a compartmentalized space separate from the vapor region comprising a phase change material to absorb energy from the heated cooling fluid.

Abstract: According to an example, a cooling system includes a cooling fluid reservoir, a cooling apparatus in fluid communication with the cooling fluid reservoir, a chamber having a side in thermal contact with a portion of the heat generating component, in which cooling fluid delivered by the cooling apparatus is to be heated through receipt of heat from the heat generating component, a cooling plate positioned at a distance and separated from the chamber, and a cooling fluid tube connecting the chamber and the cooling plate, in which the heated cooling fluid is to flow through the cooling fluid tube to the cooling plate. The cooling plate is also to be in thermal contact with a heat exchanger that that is to remove heat from the cooling fluid.

Abstract: A data center workload distribution management system includes a cooling cost engine to determine a cooling cost or cooling capacity for each of a plurality of zones of a data center and a workload distribution engine. The workload distribution engine is to identify the zone that has a lowest cooling cost and sufficient cooling capacity and also has sufficient processing capacity for a workload, determine a local cooling efficiency index for at least one location within the identified zone, and distribute the workload to the location having a local cooling efficiency index that indicates the highest cooling efficiency.

Abstract: In a method for managing a facility that is to receive resources from a first resource supply, a supply of resources available from the first resource supply is predicted for a predetermined period of time. In addition, a demand for resources in the facility during the predetermined period of time is predicted. A capacity schedule for the facility is planned to meet a predefined operational goal, in which the plan of the capacity schedule uses as inputs, the predicted supply of resources available from the first resource supply and the predicted demand for resources in the facility during the predetermined period of time. Moreover, a determination as to whether the planned capacity schedule meets the predefined operational goal is made.
