20110037721 | Printed Force Sensor Within A Touch Screen - A quantum tunneling composite, or other material exhibiting changing electrical or magnetic properties as force on the material is increased, can be located within a force concentrator integrated into traditional touch screen layers to sense force applied on the touch screen. The force concentrator can be a protrusion from the layer planes of the layers in a traditional touch screen and can be formed, at least in part, from printed elements. The amount of protrusion of the force concentrator can be adjusted through multi-pass printing and thicker deposit printing. The force concentrator can also have optically clear adhesive layered over it. The force-sensitive material can be optionally pre-loaded so as to operate within a substantially linear feedback range. A sensing mechanism can be configured to detect changes in force at multiple locations or to detect the application of force irrespective of location. | 02-17-2011 |

20130049636 | Electronic Device for Controlling Lighting Effects Using an Audio File - An electronic device is provided, which comprises one or more light groupings, each light grouping including one or more light sources, and audio processing circuitry adapted for interpreting an audio file. The audio file includes one or more instrument definitions exclusively assigned to a corresponding one of the one or more light groupings. The audio file further includes one or more note definitions associated with at least one of the one or more instrument definitions exclusively assigned to the corresponding one of the one or more light groupings, where a value associated with each of the one or more note definitions controls the color displayed by the one or more light sources within the associated exclusively assigned light grouping. In some instances, one or more commands for the instrument definitions assigned to the corresponding one of the one or more light groupings can include commands for at least one of volume definitions, note velocity definitions and modulation definitions, wherein the light intensity of the color displayed by the one or more light sources is controlled in accordance with the at least one of the volume definitions, note velocity definitions and modulation definitions. In some instances, the note definitions can include relative start times and end times, which when associated with the instrument definitions assigned to each of the one or more lighting groups affects the start time and the end time of the illumination of the light sources within the corresponding light grouping. | 02-28-2013 |
