20100131343 | System and Method for Segmenting Items in a Shopping Cart by Carbon Footprint - A method implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable medium being operable to provide a shopping cart for a shopper, and segment items in the shopping cart based on the carbon footprint associated with each item. Additionally, the method may include displaying substitute or complementary items in the shopping cart for selection by the user to reduce total carbon values, and awarding carbon certificates. | 05-27-2010 |
20090146495 | DESIGN STRUCTURE FOR A HIGH-SPEED LEVEL SHIFTER - Disclosed are embodiments of a design structure for a voltage level shifter circuit that operates without forward biasing junction diodes, regardless of the sequence in which different power supplies are powered up. The circuit embodiments incorporate a pair of series connected switches (e.g., transistors) between an input terminal and a voltage adjusting circuit. Each switch is controlled by a different supply voltage from a different power supply. Only when both power supplies are powered-up and the different supply voltages are received at both switches will a first signal generated using one of the supply voltages be passed to a voltage adjusting circuit and thereafter converted into a second signal representative of the first signal, but generated using the second supply voltage. Incorporation of the pair of series connected switches into the voltage level shifter circuit prevents forward biasing of junction diodes in the circuit and thereby prevents current leakage from the power supplies. | 06-11-2009 |
