Various aspects of invention provide portable power manager operating methods. One aspect of the invention provides a method for operating a power manager having a plurality of device ports for connecting with external power devices and a power bus for connecting with each device port. The method includes: disconnecting each device port from the power bus when no external power device is connected to the device port; accessing information from newly connected external power devices; determining if the newly connected external power devices can be connected to the power bus without power conversion; if not, determining if the newly connected external power devices can be connected to the power bus over an available power converter; and if so, configuring the available power converter for suitable power conversion.

Power managers and methods for operating power managers

A power manager including a power bus operable at a DC bus voltage. A plurality of device ports operably connect to the power bus. A first data processing device and a first memory device are associated with the first data processing device. A data communication channel extends between the first data processing device and each of the plurality of device ports. An energy management schema operates on the first data processing device. For each of the plurality of device ports, the energy management schema establishes a communication link with an external power device connected to the device port over the data communication channel and determines if an external power device is connected to the device port and if so, determines an external power device type.

A portable DC power manager () includes an internal power bus () and a plurality of device ports () for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters () may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit () connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package () enables a portability.

Portable power manager operating methods

A container seal device is provided that comprises a seal device for a shipping container, comprising a first unit that is affixed to a shipping container. A control system is contained in the first unit containing a control system. A second unit is provided that is configured to engage with an element of a door of a shipping container to which the first unit is affixed and to electrically connect with the control system in the first unit. The control system in the first unit is configured to detect a breach of the second unit indicative of access being made to the shipping container.

The data communication capacity of an existing local area network (LAN) 10 that uses a shielded twisted wire pair 16 as its transmission medium may be increased with the addition of special frequency selective terminators 36 and single-ended transceivers 20. The single-ended transceivers 20 have two single-ended transmitter connections 42,44 to the two twisted wires 22,24 in the shielded twisted wire pair medium 16, respectively, and one single-ended receiver connection 46 to one of the two twisted wires 22,24 in the shielded twisted wire pair medium 16. The shielded twisted wire pair medium 16 is terminated by the special frequency selective terminators 36 which provide transmission line impedance matching over the signal bandwidth of a single-ended data channel, while providing a high impedance over the signal bandwidth of a differential data channel. Thus, differential data communications are allowed over the signal bandwidth of the differential data channel, while single-ended data communications are allowed over the signal bandwidth of the single-ended data channel, thereby increasing the overall data communication capacity of the LAN.
