ABSTRACT:
A battery charging/data transfer structure is provided for use in conjunction with a handheld computer to charge its battery and serve as an infrared data exchange interface between the handheld computer and a data input/output device such as a desktop computer. The structure includes a support housing having an inset well area configured to receive and releasably hold a portion of the handheld computer in a docked orientation. With the handheld computer in this docked orientation a battery charging contact member in the well area contacts a charging area on the received computer portion and transfers battery-charging electrical energy thereto. Additionally, a first I/R data transceiver in the docked computer is optically coupled, via a first interface window structure in the well area and a partially transmissive mirror structure in the housing, to a second I/R data transceiver disposed within the housing and connected to the data input/output device, thereby permitting infrared data exchange in either direction between the input/output device and the docked computer. A second interface window structure on the support housing, in conjunction with the partially transmissive mirror structure, also optically couples the first and second I/R transceivers when the computer is supported in an undocked position in which the first I/R transceiver is appropriately aligned with the second interface window structure.
