Abstract
A curved battery pack may include (1) a housing comprising a curved surface and (2) a curved battery shaped to conform to the curved surface. The curved battery may be positioned relative to the curved surface such that the curved surface applies a force that counteracts a flattening force experienced by the curved battery. Various other apparatus, systems, and methods are also disclosed.
Claims20
A curved battery pack comprising:
- a substantially rigid housing comprising a curved surface;
- a substantially rigid curved battery having an initial stand-alone curvature shaped to conform to the curved surface, the substantially rigid curved battery being positioned relative to the curved surface such that the curved surface applies a first force that counteracts a first age-based flattening force exerted by the substantially rigid curved battery as the substantially rigid curved battery loses the initial stand-alone curvature;
- and
- at least one restraining member that is configured to apply a second force that counteracts a second age-based flattening force exerted by the substantially rigid curved battery as the substantially rigid curved battery loses the initial stand-alone curvature over the lifetime of the substantially rigid curved battery.

A battery-powered device comprising:
- a substantially rigid housing comprising a curved surface;
- and
- a substantially rigid curved battery having an initial stand-alone curvature shaped to conform to the curved surface, the substantially rigid curved battery being positioned relative to the curved surface such that the curved surface applies a force that counteracts an age-based flattening force exerted by the substantially rigid curved battery as the substantially rigid curved battery loses the initial stand-alone curvature over the lifetime of the substantially rigid curved battery.
A head-mounted display system comprising:
- a head-mounted display;
- a strap that is coupled to the head-mounted display and wraps around the back of a user's head when the user is wearing the head-mounted display;
- and
- a battery-pack accessory detachably coupled to the strap, the battery-pack accessory comprising:
- a substantially rigid housing comprising a curved surface;
- and
- a substantially rigid curved battery having an initial stand-alone curvature shaped to conform to the curved surface, the substantially rigid curved battery being positioned relative to the curved surface such that the curved surface applies a force that counteracts an age-based flattening force exerted by the substantially rigid curved battery as the substantially rigid curved battery loses the initial stand-alone curvature over the lifetime of the substantially rigid curved battery.
