Abstract: A system and method of using light-energy to communicate with a packaged computing device is described. In some embodiments, an optical detector of the computing device stored in a container receives light energy through a light-transparent window of the container. In some embodiments, the light energy is used to charge a battery of the computing device while the computing device is in the container. In some embodiments, a pre-defined pattern of light pulses is used to transition the computing device between a sleep state and a wake state while the computing device is in the container.

Abstract: In an implementation, a battery package includes alternating electrodes. Each electrode includes a recessed region of electrode material layers that expose a conductive layer. Each electrode also includes openings within the electrode material layers and the conductive layer, where the openings are adjacent to the recessed regions. Multilayer electro-mechanical connectors couple exposed portions of the conductive layers of alternating electrodes to thereby electrically couple electrodes that have the same polarity. Each electrode is separated from an adjacent electrode by a separator layer. The multilayer electro-mechanical connectors can pierce the separator layers and thus, the separator layers do not require additional processing.
