Method and apparatus for synchronizing and recharging a connector-less portable computer system
View Patent ↗A ruggedized connector-less cordless portable computer system is disclosed. In one embodiment, the portable computer system includes ports adapted to use wireless technology e.g., GSM. CDMA, LAN, Bluetooth, and infrared for synchronization. Furthermore, the device may be a palm-sized device having a rechargeable battery. In one embodiment of the present invention, the portable computer system includes a secondary coil of a transformer where the transformer's primary coil resides in an electronic cradle. The portable computer's rechargeable battery is recharged through an induction charging system. The wireless communication and induction charging system enables a device that is connector-less and therefor watertight and resilient to adverse climate conditions.
