Abstract: A integrated phone-based home gateway system is disclosed. The integrated phone-based home gateway system includes a broadband communication device, such as digital subscriber line (“DSL”) device, an analog modem, a wireless interface, integrated into a screen-phone for providing broadband communication service to home users. Multiple home users are able to access the Internet and the content services for conducting e-commerce, receiving content news, entertaining on-demand, making audio or video communications, and telecommuting or working at home. This screen-phone based, modular, plug-n-play home gateway interface allows in-home as well as to-home networking, provides automatic data and broadband initialization, configuration and service provisioning, routing and bridging functionality and allows resource sharing among home devices via the existing phone wire, wireless, coaxial or optical cable connections.

Abstract: A shock sensor sensitive to linear shocks along two axes and to rotational shocks in a given plane and comprised of two piezoelectric sensors and an integrated circuit is disclosed. The first piezoelectric sensor is polarized in a direction that is angularly offset from a plane in which the shock sensor lies and produces a first response to shocks having components along a first and a second orthogonal axis that define a plane perpendicular to the plane in which the shock sensor lies. The second piezoelectric sensor is polarized in a direction that is angularly offset from the plane in which the sensor lies and that is angularly offset 180.degree. from the first direction. The second piezoelectric sensor produces a second response to shocks having components along the first and second orthogonal axis. The integrated circuit is responsive to the first and second responses and produces a signal indicating a linear shock and a signal indicating a rotational shock by combining the first and second responses.
