An apparatus includes a shelf having a front edge, a solar cell circuit disposed at the front edge, a display screen, and a controller operatively coupled to the solar cell circuit and the display screen. The controller monitors the period of a waveform of a charging voltage of a storage capacitor of the solar cell circuit, displays an image on the display screen in response to a change in the waveform timing. A system includes a plurality of shelves each having a front edge, a solar cell circuit disposed at the front edge of each of the plurality of shelves, and a controller operatively coupled to the solar cell circuits. The controller monitors the frequency at which a power transfer of each solar cell circuit occurs, and signals a device in response to a change in the frequency at which the power transfer occurs.

A power sequence in a power-delivery (PD) mechanism (interaction between host system components and a charger) and a firmware sequence during power contract negotiation reduces the host system power consumption at or below the pSnkStdby power limit to improve user experience and battery life. The power sequence uses USB Type-C PD protocol and timing specification to implement a synchronous trigger or interrupt and interface mechanism. The synchronous trigger or interrupt and interface mechanism between a PD controller and an embedded controller firmware controls the power consumption dynamically during the boot flow sequence to be less than or equal to pSnkStdby power limit while implementing a predictable boot sequence and optimizing boot time. The power negotiating sequence is also applicable when a source (e.g., a charger) is connected to a SoC host system which is in active state (e.g., S0) and when there is an indication of low battery capacity.
