Satellite digital assistant and host/satellite computer system wherein coupling the host and the satellite by a host interface communication system results in digital communication and synchronization of files
DCFirst Claim
1. A combination host/satellite computer system comprising:
- a host computer having a host CPU, a host memory, and a host communication interface coupled to the host CPU; and
a satellite digital assistant having a satellite CPU, a satellite memory, and a satellite communication interface coupled to the satellite CPU, the satellite communication interface compatible with the host communication interface;
wherein coupling the host computer to the satellite digital assistant through the host and satellite communication interfaces causes automatic synchronization, without manual input or initiation by a user, of stored entities between the host computer and the satellite digital assistant, such that stored entities having the same identification in the host memory and the satellite memory, but having different time or date stamps, are updated to the latest version.

Abstract
A personal digital assistant module with a local CPU, memory, and I/O interface has a host interface comprising a bus connected to the local CPU and a connector at a surface of the personal digital assistant for interfacing to a bus connector of a host general-purpose computer, providing direct bus communication between the personal digital assistant and the host general-purpose computer. In an embodiment, the personal digital assistant also stores a security code. The personal digital assistant according to the invention forms a host/satellite combination with a host computer having a docking bay, wherein upon docking a docking protocol controls access by the host to memory of the personal digital assistant based on one or more passwords provided by a user to the host. In another embodiment the personal digital assistant also has an expansion port connected to the local CPU, and expansion peripheral devices may be connected and operated through the expansion port.
