A system and method for detecting anomalies and malicious processes by analyzing current consumption profiles is disclosed. The technique involves generating current consumption profiles that characterize the expected power draw for known software applications operating in various modes on a target device. At runtime, the current being consumed by actively running applications is measured and compared to the total expected current draw determined from the individual profiles. Deviations between the observed and expected consumption indicate potential interference from malware or other unwanted processes. Additionally, current fluctuation profiles are generated to model the characteristic transient current behavior when applications transition between operational modes. By comparing runtime current measurements during state changes to these expected transitional profiles, the system can identify aberrations indicative of background malware triggering during the transitions. The current monitoring approach provides an efficient way to detect anomalous behavior from unwanted processes with minimal overhead.

Based on a PMOS turn-off voltage selection module, a voltage capable of turning off a PMOS (switch) is selected from an external power supply voltage and a standby battery voltage as a grid voltage, so that an electric leakage phenomenon when the PMOS is turned off is avoided, and the circuit stability is ensured.

The bootstrap circuit comprises an enable signal generating circuit, a first transistor, a bootstrap capacitor, a voltage feedback circuit, an error amplifier and a charge pump. Through the bootstrap circuit provided by the invention, when the switching converter is in a high resistance state, most of circuit modules needing to consume quiescent current in a bst-sw voltage domain are closed, the voltage difference in the bst-sw voltage domain does not need to be monitored, the quiescent current consumption in the bst-sw voltage domain is ensured to be minimum, and only leakage consumption of each logic circuit exists. Meanwhile, through the charge pump, when the switching converter is in a high-resistance state, the node voltage is utilized to charge and complement energy for the bootstrap voltage, so that after the switching converter exits from the high-resistance state, the switching converter has a quick response capability to open a high-side switching tube to output power.

An electroactive lens with raised resistive bridges is disclosed. The resistive bridges can connect many ring electrodes in an electroactive lens with a relatively small number of bus lines. These resistors are typically large to prevent excessive current consumption. Typically, they are placed in the same plane as the ring electrodes, which means that the ring electrodes are further apart or made discontinuous to accommodate the resistors. But further separating the ring electrodes or making them discontinuous degrades the optical quality of the lens. Placing the ring electrodes and resistors on layers separated by an insulator allows the ring electrodes to be closer together and continuous and have a high enough resistance to limit current consumption. It also relaxes the constraints on feature size and placement during processing to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities.
