A building automation system that is comprised of a plurality of network connected electrical modules contained in standard receptacle gang boxes for outlets and switches is described. The system includes an AC to DC power supply, a bidirectional solid state dimmer switch, a microprocessor, and, interconnected sensors that are powered and controlled by microprocessors within the electrical modules. The electrical modules include a user interface for programming and control. The system provides enhanced safety and security, power metering, power control, and home diagnostics. The apparatus replaces existing outlet receptacles and switches with a familiar flush but elegantly updated and seamlessly integrated faceplate.

A device includes a substrate is substantially transparent and includes a contact surface and an interface surface. The interface surface includes a plurality of electrical contacts. The device further includes a semiconductor die, which includes a plurality of connections, a first photo detector and a second photo detector. Each of the plurality of connections includes a connection bump formed thereon to couple to the plurality of electrical contacts of the interface surface of the substrate. The plurality of connections positioned relative to the first and second photo detectors to alter a directional response of at least one photo detector of the plurality of photo detectors.

Device including multi-function circuitry having optical detectors and method of flip-chip assembly therefor

A touch panel scan system is disclosed for detecting a change in mutual capacitance on the surface of a touch panel. A first touch detect device is provided having a transmitter for transmitting a transmit signal to a select one of a plurality of first lines on a first edge of a touch panel to facilitate a single line scan operation. A second touch detect device is interfaced with a select one or ones of second lines on a second edge of the touch panel having a receiver for receiving therefrom and processing thereof transmit signals coupled thereto from the select one or ones of the first lines to detect changes in a mutual capacitance associated with the select one or ones of the second lines and the first line. At least one of the first or second touch detect devices functions as a master and the other functions as a slave, with the master coupled to the slave and generating a SYNC signal to initiate a single scan operation of a select one of the first lines.

Method and apparatus for scanning a touchscreen with multi-touch detection using master/slave devices

In one form, a keypad includes a substrate and a flexible membrane disposed above a top surface of the substrate. The substrate has the top surface, a first conductor below the top surface, an insulator layer separating the first conductor from the top surface, and a second conductor disposed in proximity to the first conductor and to the top surface and coupled to a voltage terminal. The flexible membrane is disposed above the top surface of the substrate and has a third conductor forming a key. The third conductor is movable relative to the top surface. In another form, a keypad system includes such a keypad and a capacitive sensing circuit coupled to the first conductor for sensing a change in capacitance between the first conductor and the voltage terminal when the third conductor moves relative to the top surface.
