A method and device for determining the length of at least one of two legs, of a workpiece bent toward each other at a bending angle requires location of the workpiece in a defined position. Contact fingers mounted on the base of the socket extend through a bending plate and into the windows from the opposite side of the top surface. It includes a gas selection device, an automatic shut off of the carbon dioxide, a purging system, metering of the gases and a mixing chamber to promote a homogeneous mixture of gases and sized for field use by emergency care operators. An asymmetric etch of a gate dielectric cap, application of a planarization material layer, and a non-selective etch of the planarization material layer and the gate dielectric cap can be employed to form the DRAM cell. When the data decay potential exceeds a predetermined threshold, an indicator such as a report, an alarm, an error message, or an event and be communicated, and a remediation action such as a format transformation, a software archiving, or an environment archiving can be initiated. The payment processing server can send a confirmation of the executed transaction to the merchant and the mobile device.
