Abstract: A method and system for conditionally carrying out an operation defined in a computer instruction wherein a computer instruction is implemented on so-called packed operands; that is, operands containing a plurality of packed objects in respective lanes. An operation defined in the computer instruction is conditionally carried out in dependence on stored condition values which determine for each lane whether or not the operation is to be executed on objects in that lane.

Abstract: A power supply and switching technique is provided that utilizes a first battery and a second battery to charge a load. The power supply includes a first controlled power switch coupled to the first battery and the load, a second controlled power switch coupled to the second battery and the load, and a power controller coupled to the first controlled power switch, the second controlled power switch, and the load. The power controller monitors the voltage and the load and causes a charge to be applied to the load when the load voltage is not a predetermined voltage. The power controller causes a charge to be applied to the load by selectively closing the first controlled power switch, thereby providing a charge from the first battery to the load, and/or selectively closing the second controlled power switch, thereby providing a charge from the second battery to the load. A similar switching technique may be used to recharge the first and second battery by alternately coupling them to an external power source.

Abstract: A method for manufacturing a piezoelectric element is disclosed. The method includes the steps of forming a lower electrode over a substrate, forming a piezoelectric luminous film over the lower electrode, forming an upper electrode over the piezoelectric film, forming a pressure luminous layer for emitting light upon application of pressure on the upper electrode, and attaching a substrate to the pressure luminous layer—has been inserted as a new abstract.
