Abstract
Apparatus, systems and methods are provided for controlling energy consumption by a selectively enabled processing system, such as a high-density code scanner. The selectively enabled processing system has at least one high-power consumption microprocessor which does not include a low-power consumption mode. Also included are a power-supply, a switch and a trigger for turning ON and OFF the power-supply, and means for performing diagnostics. The performing diagnostics means operate on at least a portion of the selectively enabled processing system whenever the power-supply is initially switched ON, and inhibit the power-supply upon diagnostics completion. The trigger selectively enables means for causing the microprocessor to consume the power-supply for a pre-set time period while processing, and then inhibit the power-supply upon expiration of the time period without re-performing diagnostics.
