Point of sale device power management and undervoltage protection

This invention describes a system for managing power in a portable Point-of-Sale (POS) device. It works by constantly checking how much power the battery can safely deliver and how much power the device's parts, like a printer or card reader, are expected to use. If the device is about to draw too much power, the system intervenes by, for example, temporarily turning off a less critical part to prevent the device from failing. The claims specifically describe a method for deciding which component to disable to best reduce the risk of power issues.

Why it matters: Filed before advanced embedded processors could efficiently handle the real-time predictive power calculations on-device. Modern low-power chips make this intelligent management more practical.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, power management algorithms
