Filed:

Apr 15, 2013

Appl. No.:

13/863200

Inventors:

Winston Cheng - El Cerrito CA, US

Assignee:

Aeon Labs - Santa Clara CA

International Classification:

H03K 17/96

US Classification:

200600

Abstract:

Wall mountable touch panels are described. In one embodiment, a wall mountable touch panel for controlling a load device includes a touch sensor configured to receive a user touch input and to control the load device based on the user touch input and a power interface configured to receive a low-voltage direct current (DC) power signal for powering the touch sensor. Other embodiments are also described.

Inventors:

Winston Cheng - El Cerrito CA, US

Assignee:

Aeon Labs - Santa Clara CA

International Classification:

H02M 7/04

US Classification:

363 84

Abstract:

Electrical devices are described. In one embodiment, an electrical device suitable for installation in an electrical gang/patress box includes an alternating current (AC) to direct current (DC) transformer configured to transform an AC power signal that is accessible from within the electrical gang/patress box into a DC power signal, a load regulator module configured to regulate a load device in response to the DC power signal, a microcontroller module configured to control the load regulator module in response to the DC power signal, and a connector configured to output a DC voltage signal having a voltage that is lower than the voltage of the AC power signal in response to the DC power signal. Other embodiments are also described.

15/201343

Inventors:

Bernard Kok Yien Kwan - El Cerrito CA, US
Winston Cheng - El Cerrito CA, US

International Classification:

G02F 1/1345
H01R 24/66

Abstract:

Embodiments of an apparatus for connection to a light adjustment sheet and conductive interfaces for connection to a light adjustment sheet are described. In one embodiment, an apparatus for connection to a light adjustment sheet include a power source interface configured to be connected to a power source and a sheet interface electrically connected to the power source interface. The sheet interface is configured to connect to the light adjustment sheet such that electricity can be conducted from the power source interface to the light adjustment sheet to switch the light adjustment sheet between different visibility states. Other embodiments are also described.

Appl. No.:

14/086915

Inventors:

Winston Cheng - El Cerrito CA, US

International Classification:

H02M 7/32

US Classification:

363140

Abstract:

Electrical devices, methods of operating an electrical device for use with a multiway switch system, and methods for connecting an electrical device with a load device and a multiway switch system for controlling the load device are described. In one embodiment, an electrical device for use with a multiway switch system includes an alternating current (AC) power interface configured to connect to at least one of a live wire and a neutral wire of an AC power supply, a load regulator module configured to regulate a load device that is connected to the neutral wire of the AC power supply, an output power interface configured to connect to the multiway switch system and to output a voltage to a switch of the multiway switch system, and a microcontroller module configured to control the load regulator module in response to a switching of the multiway switch system.
