Abstract: A microfluidic device includes a microfluidic coupon and at least one fluid channel associated with the microfluidic coupon. The fluid channel is configured to control fluid flow from one portion of the coupon to another portion of the coupon. A quantity of reconfigurable valving material is disposed within the fluid channel, the valving material being thermally coupled to an optically activatable material operable to increase a temperature of the valving material when exposed to an optical beam to at least partially soften at least one component of the valving material to allow reconfiguration of the valving material to switch a flow state of the fluid channel.

Abstract: An optical display element of one embodiment of the invention is disclosed that comprises a binary optical display element and a multiple-bit storage element to store a number of bits of a color intensity value to be displayed by the binary optical display element during a display period. Each bit is loaded from the multiple-bit storage element into the binary optical display element one or more times during the display period to achieve the color intensity value.

Abstract: Subject matter includes an electric charge counting fuel gauge that displays an amount of fuel based on electric charges obtained from a fuel. The electric charge counting fuel gauge can display an amount of fuel used in a power source and the amount of fuel remaining in a fuel supply.

Abstract: Disclosed are systems and methods for transmitting graphical data via a communication line. For example, in one embodiment, a system includes means for receiving voice data, means for generating graphical data representative of a user input, and means for simultaneously transmitting the voice data and information representative of the generated graphical data via a communication line such that a bandwidth of the communication line is not exceeded.

Abstract: A system and method for erasing a high-density non-volatile fast memory is presented. In one embodiment the high-density non-volatile fast memory is a modified flash memory having modified flash cells. One embodiment of the system comprises ultra-violet (UV) light windows that permit exposure of the modified flash cells to UV light. The exposure of UV light onto the modified flash cells erases the modified flash cells.
