Abstract
Embodiments of a system, topology, and architecture for providing power and transceiving data to electronic devices having an interface are described generally herein. Other embodiments may be described and claimed.
Claims20
An apparatus for providing power to a portable electronic device (PED), the PED including an electrical energy storage element, including:
- a first housing, the first housing mechanically separatably from the PED, the first housing substantially including a first power interface module (PIM), the first PIM including at least two electrical contacts configured to be releasably and directly coupled with the PED, the PIM at least two electrical contacts configured to provide a direct current (DC) power signal;
- and
- a second housing, the second housing physically separate from the PED and coupled to the first housing via a substantially flat, flexible cable, the second housing including an external power source interface (EPSI), the (EPSI) including at least two separate electrical contacts configured to receive a DC electrical signal, and a converter module coupled to the EPSI, the converter module converting a DC signal from the EPSI having a first voltage level to a DC signal having a lower, second voltage level;
- the substantially flat, flexible cable fixably coupling the first housing to the second housing and including at least one wire pair, the wire pair coupling the first housing first PIM at least two electrical contacts to the second housing converter module to provide the DC signal having the lower, second voltage level to the first PIM at least two electrical contacts.

An apparatus for providing power to a first portable electronic device PED and a second PED, the apparatus including:
- a first housing, the first housing mechanically separatably from the PEDs, the first housing substantially including a first power interface module (PIM), the first PIM including at least two electrical contacts configured to be releasably and directly coupled with one of the first and the second PED, the PIM at least two electrical contacts configured to provide a direct current (DC) power signal;
- a second housing, the second housing physically separate from the PEDs and coupled to the first housing via a flexible cable, the second housing including an external power source interface (EPSI), the EPSI including at least two separate electrical contacts configured to receive a DC electrical signal, a converter module coupled to the EPSI, the converter module converting a DC signal from the EPSI having a first voltage level to a DC signal having a lower, second voltage level, and a second power interface module (PIM), the second PIM including a least two electrical contacts configured to be indirectly coupled with the other of the first and the second PED and coupled to the converter module to provide the DC signal having the lower, second voltage level to the second PIM at least two electrical contacts;
- and
- the flexible cable fixably coupling the first housing to the second housing and including at least one wire pair, the wire pair coupling the first housing first PIM at least two electrical contacts to the second housing converter module to provide the DC signal having the lower, second voltage level to the first PIM at least two electrical contacts.
