A modular refrigeration unit (MRU) health monitor includes a log data input configured to receive log data from an MRU, the log data comprising a plurality of datapoints, each of the plurality of datapoints comprising a position of a control valve of the MRU and a corresponding time; and MRU health monitoring logic configured to determine a plurality of MRU parameters from log data received on the log data input; determine a plurality of MRU health flags based on the MRU parameters; add the plurality of MRU health flags to determine an MRU health score; determine whether the MRU health score is higher than a replacement threshold; and indicate replacement of the MRU in the event the MRU health score is higher than the replacement threshold.

Modular refrigeration unit health monitoring

A method for modular refrigeration unit (MRU) health monitoring includes receiving log data on a log data input from the MRU by a MRU health monitor, the log data comprising a plurality of datapoints, each of the plurality of datapoints comprising a position of a control valve of the MRU and a corresponding time; determining by the MRU health monitor a plurality of MRU parameters from the log data; determining a plurality of MRU health flags based on the MRU parameters; adding the plurality of MRU health flags to determine an MRU health score; determining whether the MRU health score is higher than a replacement threshold; and indicating replacement of the MRU in the event the MRU health score is higher than the replacement threshold.

Automated control of a cooling system cooling at least one electronic component is provided. The control includes monitoring over a period of time variation of an operational variable of the cooling system or of the at least one electronic component, and based, at least in part, on variation of the operational variable over the period of time, automatically determining whether to adjust control of the cooling system to limit variation of the operational variable. In one implementation, depending on the variation of the operational variable, and whether control of the cooling system has been previously adjusted, the method may further include automatically determining a probability of fail or an expected residual life of the cooling system, and responsive to the predicted probability of fail exceeding a first acceptable threshold or the expected residual life being below a second acceptable threshold, automatically scheduling for a cooling system repair or replacement.

Cooling system control and servicing based on time-based variation of an operational variable

An interface layer for separating first and second microelectronic ceramic substrates during firing includes a thermally degradable binder, preferably a polymer, that degrades at temperatures above room temperature and below a firing temperature for the microelectronic ceramic substrates, and a separating material, such as boron nitride or graphite. The method of making the interface layer includes mixing the binder, one or more solvents for the binder, a plasticizer and the separating material for a sufficient period of time to form a homogeneous mass, then casting the material in a thin sheet to form the interface layer.

Method of making an interface layer for stacked lamination sizing and sintering

A process for making multiple microelectronic ceramic substrates uses an interface layer between stacked layers of green sheets that are laminated with the interface layer, then fired to produce the ceramic substrates. The interface layer acts to protect the substrates, and to hold them together before firing, then thermally degrades at a desired point in the firing cycle to separate the individual substrates. The invention also includes the ceramic substrates produced by the method.
