Filed:

Oct 3, 2006

Appl. No.:

11/543185

International Classification:

G06F 11/00

US Classification:

714 47

Abstract:

A networked configuration of structural health monitoring elements. Monitoring elements such as sensors and actuators are configured as a network, with groups of monitoring elements each controlled by a local controller, or cluster controller. A data bus interconnects each cluster controller with a router, forming a networked group of “monitoring clusters” connected to a router. In some embodiments, the router identifies particular clusters, and sends commands to the appropriate cluster controllers, instructing them to carry out the appropriate monitoring operations. In turn, the cluster controllers identify certain ones of their monitoring elements, and direct them to monitor the structure as necessary. Data returned from the monitoring elements is sent to the cluster controllers, which then pass the information to the router.

Abstract:

A portable computer includes a display portion comprising a display and a base portion pivotally coupled to the display portion. The base portion may include a bottom case and a top case, formed from a dielectric material, coupled to the bottom case. The top case may include a top member defining a top surface of the base portion and a sidewall integrally formed with the top member and defining a side surface of the base portion. The portable computer may also include a sensing system including a first sensing system configured to determine a location of a touch input applied to the top surface of the base portion and a second sensing system configured to determine a force of the touch input.
