Abstract
A wearable computer system includes a processing unit (102) and a number of peripherals. The processing unit and peripherals are coupled in a daisy-chain fashion utilizing a serial bus (120). The processing unit has a single connector for implementing the serial bus, and peripherals each have two connectors for propagating the serial bus. The wearable computer system has only one unused connector at any one time, thereby reducing excess bulk and weight due to excessive unused connectors. When a peripheral interrupts the processing unit, the processing unit relinquishes the serial bus to the interrupting peripheral. Alternatively, peripherals are assigned time slots within which the peripherals can utilize the serial bus.
