Abstract: The present disclosure relates to methods of manufacture of piezoelectric ceramic transducers useable, for example, in an ultrasound probe, using a poling process. The poling is accomplished without contacting transducer elements and by subjecting the piezoelectric ceramic transducer to a corona discharge. The disclosure further describes a system for poling a transducer comprising at least one piezoelectric ceramic component or transducer assembly, a ground plane comprising an electrical polarity, and a corona source connected to a first power source configured to supply a first voltage to the corona source having an electrical polarity opposite the electrical polarity of the ground plane. The at least one piezoelectric ceramic component or transducer assembly is positioned between the corona source and the ground plane within a chamber.

Abstract: A system for managing battery temperature is described. The system may include a cooling system which may include a fluid. A cabin circulation subsystem may be coupled to the cooling subsystem and may utilize the fluid for cabin cooling. A separate battery circulation subsystem may also may also be coupled to the cooling subsystem so that it may additionally utilize the fluid for battery cooling. A control may be present in order to regulate movement of the fluid to the cabin circulation subsystem and/or to the battery circulation subsystem.
