Abstract: An airflow health predictive maintenance system and method for a motor drive includes a differential pressure sensor that senses an air pressure differential between a sensing location within an enclosed cabinet space of the motor drive and a reference location. The system includes an electronic control system configured to select a setpoint that indicates that airflow through the cabinet space has reached a value associated with a need for air filter maintenance. The control system is further configured to obtain air pressure differential measurements periodically from the differential pressure sensor and generate an actual trend comprising a series of values, wherein each of the values of the actual trend is derived from one or more of the air pressure differential measurements.

Abstract: Systems and methods for estimating electrical component degradation caused by an operating parameter that stresses the component in a series of stress cycles, in which cycle count values are maintained which individually correspond to a range of values of the operating parameter, and a plurality of maximum cycle values are stored, which individually correspond to one of the ranges and represent the number of stress cycles in the corresponding range at which the component is expected to have a user defined failure probability value. For a given stress cycle, one of the count values is incremented that corresponds to the range that includes a measured or sensed value, and a cumulative degradation value for the electrical system component is computed as a sum of ratios of the individual count values to the corresponding maximum cycle values.

Abstract: A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.

Abstract: A system and method for the monitoring and treating of a coolant in a cooling system of an MRI system includes a deionization kit connectable to the cooling system of the MRI system. The deionization kit receives coolant from the cooling system to deionize the coolant and forms a closed-loop system with the cooling system when connected thereto. The deionization kit thus allows for unimpeded circulation of the coolant through the deionization kit and the cooling system. Accordingly, the MRI system may remain in operation and be used to perform MR image acquisitions of an object while the deionization kit is connected to the cooling system.

Abstract: An improved cooling fan (12) fan for cooling an electronic component includes a rotor (26) rotatably mounted in a housing (18) and having a plurality of fan blades (28). The housing (18) includes a first end (20), a second end (24), and a passage (24) interconnecting the first end and the second end to define an air flow path (25) therebetween. An entry port (16) is defined by an upstream portion of the housing (18) generally adjacent the housing first end (20), with the entry port (16) having a cross-sectional area greater than a cross-sectional area of the passage (24). The entry port (16) and the passage (24) being separated by a transition zone (30), with the entry port (16) and the transition zone (30) cooperating to define an abrupt step (36). The abrupt step (36) is adapted to at least partially affect the flow of air flowing along the flow path (25), thereby reducing the ambient noise level of the fan.
