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.

Various embodiments are directed to flexible battery structures comprising a flexible hinge region. For example, a flexible battery structure may comprise a plurality of battery layers. A first portion of the layers may be continuous across the hinge region and one or more cell regions. A second portion of the layers may be discontinuous at the hinge region.

Flexible battery

Various embodiments are directed to a flexible battery structure comprising patterned active layers. An example battery structure comprises a sheet of current collector material, first and second active layers, and a first electrolyte layer. The first active layer may be disposed on the sheet and may comprise a plurality of active material portions and a plurality of slots, where each of the plurality of slots separates a set of at least to adjacent active material portions.

An embedded power cell is formed by placing a cathode, anode, and electrolyte within a recess in an enclosure. The enclosure thus acts as part of an overall device and also contains the embedded power cell, eliminating the need for dedicated packaging for the power cell. In one implementation, a low-profile lithium ion battery with a polymerized electrolyte may be sealed within the enclosure. Other devices such as a cell temperature sensor, battery controller, and so forth may also be embedded within the enclosure.
