A system for determining a health of a bearing associated with a connecting rod is provided. The system includes a sensor associated with the connecting rod and remotely disposed relative to the bearing of the connecting rod. The sensor is configured to generate a signal indicative of a temperature of the bearing. The system includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the bearing. The controller further determines a health of the bearing as a function of the signal of the temperature of the bearing.

System and method for determining a health of a bearing of a connecting rod

The present disclosure provides an apparatus and method for removing particulates from a gas stream. The apparatus includes a ceramic filter, at least one electrode, and at least one conductor. The electrode is located at an end of the filter and produces an atmospheric glow discharge in order to oxidize carbon deposits trapped in the filter. The conductor extends at least partially into the filter and acts as a counter electrode. Through various arrangements of the electrodes and conductors, the present disclosure provides closer connection between the trapped carbon deposits and the electrodes. This improves the regeneration of the filter without increasing the size and/or weight of the apparatus.

Autoselective regenerating particulate filter

The present disclosure is directed towards a clamping assembly for compressing a plurality of optical plates of a high pressure cavitation system. The clamping assembly may include a mounting frame and a housing coupled to the mounting frame. The clamping assembly may further include a holder distal the housing, the holder having the plurality of optical plates disposed therein. The clamping assembly further including a controllable clamping mechanism operably coupled to a top of the housing, the controllable clamping mechanism applying an axial force to the plurality of optical plate.

High pressure cavitation system

Coolant systems, for power sources (e.g. internal combustion engines, fuel cells, and nuclear reactors) or microprocessors for example, are beneficially operated with coolant in a nucleate boiling state, but transitions to damaging film boiling are then possible. The disclosed coolant system includes a sensor, such as a thermocouple or thermistor, that provides a signal representative of fluctuations in the temperature at a heated surface. The signal also includes at least one parameter. A controller processes the signal to determine changes in the parameter of the signal and/or to determine the state of the coolant and can responsively change the coolant flow to avoid undesirable coolant states. For example, coolant flow can be changed by changing the output of a coolant pump. The controller can change coolant flow automatically, or a signal can be provided to an operator that an undesirable coolant state change is imminent or has occurred, thereby allowing operator intervention. The system may also be used with liquids other than coolant.

Liquid/coolant system including boiling sensor

An apparatus for removing particulates from a gas stream is described comprising a filter through which gas may be caused to flow, at least one first electrode for producing an atmospheric glow discharge located near to but spaced apart from the filter, and at least one second counter electrode, the electrodes being connected to an AC voltage supply generating an AC voltage in a frequency within the range of 1 kHz to 200 kHz. A method of removal of particulates from a gas stream comprising causing the gas to flow through such an apparatus is also described.

Heat transfer in coolant circuits, as in an internal combustion engine for example, can be beneficially enhanced by maintaining the coolant in a nucleate boiling state, but undesirable transitions to a film boiling state are then possible. The disclosed coolant circuit has selected surface(s) that have a tendency to experience high heat flux in comparison to adjacent surfaces in the coolant circuit. These surfaces are provided with a surface configuration, such as a matrix of nucleation cavities, which has a tendency to inhibit a change in boiling state. The surface configuration can be provided on the parent coolant circuit surface or on a surface of an insert positioned in the coolant circuit. Thus, transitions to film boiling can be effectively avoided at locations in the coolant circuit that are susceptible to such transitions.
