Enhanced identification of sources of delays in packet delivery along a path
An initial test is executed to determine an end-to-end latency of a path between a source and a destination. Subsequent tests incrementally target each node of the path for measurement of metric values indicative of delay of the nodes (e.g., latency, jitter, and packet loss). As tests are performed incrementally for each node, the maximum observed latency is tracked and used for calculating timeout thresholds. For the first hop, the timeout threshold is determined relative to the end-to-end latency; for subsequent hops, the timeout threshold is determined relative to the maximum non-timeout latency measured for a previous hop. Each test is performed N times to obtain additional values of delay metrics for each node. Upon completion of the N passes through the path, the resulting delay metric values determined for each test set are aggregated to yield a single, comprehensive result set. |

Methods and apparatus for controlling cooling capacity of a multi- evaporator cooling system
A vapor-compression multi-evaporator cooling system comprises a cooling control system and two or more evaporators each coupled to an expansion valve. Each evaporator is selectively enabled or disabled during operation. When an evaporator is enabled, the evaporator transfers heat into a working fluid within the system. When an evaporator is disabled, the evaporator does not exchange any appreciable amount of heat within the system. The cooling control system includes a cooling controller, an adjustable compressor, a condenser, and a variable speed fan that provides selectable amounts of cooling to the condenser. During operation, the cooling controller adjusts the compressor operation and fan speed to maintain stable operation of the cooling system. To compensate for enabling or disabling of evaporators, the cooling controller adjusts compressor operation and fan speed to provide more or less compression and more or less condenser cooling to maintain stable and efficient operation of the cooling system. |

Dispersion of stored energy within a battery system at risk of failure
A method and system for dispersing stored energy in an energy storage system to delay or arrest propagation of thermal runaway and thermally-induced cascading failures. The system includes a plurality of battery sub-assemblies and DC-DC converters connected to a shared DC bus through which energy may be exchanged. The system may be interfaced to an AC power grid or DC power system through an additional power converter.

The method determines, based on awareness of current system state, battery types, and electrical and thermal structure, the sequence of charging and discharging actions to best inhibit thermal runaway while preserving the system's ability to perform subsequent energy redistribution. |
