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.

Abstract: A telecommunication interface provides a user or recipient with the capability of a reduced-stressed environment. In particular, the telecommunication interface is interfaced with a telephone system at a call recipient location. The telecommunication interface may be configured to detect an incoming telephone call. The telecommunication interface intercepts the incoming telephone call prior to the ringing and presents the caller with a menu of several options to contact the users at the call recipient location. The telecommunication interface may be configured to place the caller on hold and to send a message to a portable notifier carried by the specific user in response to a selection of the user by the caller. The portable notifier vibrates or visually cues the user of an incoming telephone call or message. The portable notifier may display answering options for the specific user.
