ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to interface devices, and more particularly to a smart wall charger for creating an interface between a portable capture device and a variety of other devices.
There exists a need for a portable, light-weight device to allow a portable capture device such as a portable scanner or digital camera to be able to communicate with another communication device.
SUMMARY OF THE INVENTION
The present invention comprises, in one embodiment, a smart charger including: a housing with a first interface for power transmission and data transmission and adapted for connection to a first communication device, with a second interface adapted for connection to a power source, and with a third interface adapted for connection to a second communication device; a charger disposed within the housing and connected to the second interface to receive power, and connected to the first interface to provide charging power; and a control module disposed within the housing and connected to receive information from the first interface and to provide output information to the third interface. The first interface may be adapted to communicate, by way of example, to a scanner or a digital camera, and the third interface may be adapted to communicate with a printer, computing resource or other appropriate interface.
In one aspect of the present invention, the first interface includes a data interface and control module to translate data received at the first interface from a first data protocol to a second data protocol for communication to the third interface.
In a further aspect of the present invention, the data interface and control module includes a wireless interface chip for receiving wireless communication at the first interface.
In a yet further aspect of the present invention, the first interface is adapted to communicate with an information capture device; and the third interface includes a telephone line interface and a computing resource interface; and further comprises a data interface and control module to translate data received from the first interface from a first data protocol to a second data protocol and logic for selecting the telephone line interface or computing resource interface.
In a further aspect of the present invention, a user interface is provided to allow for a user to select the telephone line interface or computing resource interface at the third interface.
In a second embodiment of the present invention, a smart charger is provided, comprising: a housing with a first interface for power transmission and data transmission and adapted for connection to a first communication device, with a second interface adapted for connection to a power source, and with a third interface with at least two I/O ports, with each I/O port adapted for communication with a different type of second communication device; a charger disposed within the housing and connected to the second interface to receive power, and connected to the first interface to provide charging power; and an I/O control module adapted for selecting one of the I/O ports at the third interface for data communication with the first interface.
