A system is provided for detecting when an enclosure having a body and a removable cover is opened. The system comprises a light source for generating a light beam, a light detector for detecting the light beam, and at least one reflector all mounted inside the enclosure. The reflector reflects the light beam along a predetermined pathway toward the light detector when the removable cover is closed over the body.

Systems and/or methods are provided for an inverter power module with distributed support for direct substrate cooling. An inverter module comprises a power electronic substrate. A first support frame is adapted to house the power electronic substrate and has a first region adapted to allow direct cooling of the power electronic substrate. A gasket is interposed between the power electronic substrate and the first support frame. The gasket is configured to provide a seal between the first region and the power electronic substrate. A second support frame is adapted to house the power electronic substrate and joined to the first support frame to form the seal.

A cooling system is provided for an electric motor and comprises a rotor assembly, an intake assembly, and a first reservoir. The rotor assembly is coupled to and rotatable within a housing, and comprises a rotor having a first and second ends having a first plurality of veins extending therebetween, each vein having an inlet and an outlet. The rotor assembly also comprises a first manifold coupled to and rotatable with the first end of the rotor in fluid communication with the inlets of the first plurality of veins. The intake assembly is coupled to the housing and is in fluid communication with the first manifold. The first reservoir is configured to contain a motor coolant and is coupled to the housing for collecting the motor coolant from the outlets of the first plurality of veins, and for providing a source of motor coolant to the intake assembly.

A manifold is provided for supporting a power module assembly with a plurality of power modules. The manifold includes a first manifold section. The first face of the first manifold section is configured to receive the first power module, and the second face of the first manifold section defines a first cavity with a first baseplate thermally coupled to the first power module. The first face of the second manifold section is configured to receive the second power module, and the second face of the second manifold section defines a second cavity with a second baseplate thermally coupled to the second power module. The second face of the first manifold section and the second face of the second manifold section are coupled together such that the first cavity and the second cavity form a coolant channel. The first cavity is at least partially staggered with respect to second cavity.

A printed circuit board includes, but is not limited to, a plurality of electrically conductive layers and a plurality of dielectric layers. Each dielectric layer is interposed between adjacent conductive layers to form a body of alternate conductive layers and dielectric layers. At least one of the electrically conductive layers protrudes beyond an end of the body.
