Patent number: 9472320Abstract: A Metal-Clad cable includes at least two conductor assemblies and a non-linear bonding/grounding conductor within a metal sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. The bonding/grounding conductor includes a plurality of undulations disposed along a length thereof, and is disposed within the metal sheath so that it is in contact with an interior surface of the metal sheath. The bonding/grounding conductor is in cabled relation with the conductor assemblies. The undulations of the bonding/grounding conductor provide a degree of resiliency to the connection between the conductors and the metal sheath to facilitate easy removal of the metal sheath when making terminal connections.Type: GrantFiled: March 16, 2012Date of Patent: October 18, 2016Assignee: WPFY, Inc.Inventors: Stephen A. Lundgren, Skip N. Afdasta, Robert A. Pereira

Patent number: 6650537Abstract: A DC distribution module for a power supply unit is modular and facilitates thermal cooling of the unit. The power supply unit preferably includes a housing in which one or more power supply modules and the DC distribution module can be inserted. The DC distribution module preferably comprises two power conductors laminated and bonded to a ground conductor. The DC distribution module is relatively thin compared to the power supplies inserted into the power supply unit. By being relatively thin, the DC distribution module, which may carry substantial amounts of current, does not substantially interfere with air movement through the power supply unit for thermal cooling purposes.Type: GrantFiled: October 31, 2001Date of Patent: November 18, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert A.
