    摘要: Systems, devices, media, and methods are presented for capturing and sharing visual content, especially three-dimensional video, with a plurality of users with compatible devices. The methods in some implementations include transmitting the visual content to a portable projector, generating a unique invite and broadcasting it to a plurality of eyewear devices, and projecting the visual content onto a screen for viewers who accepted the invite and are wearing a compatible eyewear device. For projection in 3D format, the eyewear devices include an active shutter mode. The portable projector may be housed in the interior of a case. In some configurations, the case interior is sized and shaped to support the projector and an eyewear device. The system may include multiple projectors at remote locations directed to project the visual content simultaneously.

    摘要: A secondary battery pack comprises a battery and a protection circuit module (PCM), a pair of electrodes of the battery being connected to a protection circuit board (PCB) forming part of the PCM such that the electrode connections are located on a face of the PCB other than a major face that receives PCM components thereon. In some embodiments, the PCM components are mounted on one of a pair of major faces of the PCB, the electrode connections being located on the opposite one of the major faces. In other embodiments, the electrode connections are located on a peripheral edge face that extends transversely between the pair of major outer faces of the PCB. The spatial arrangement of the electrode connections and the PCM components on the PCB is such that substantially the entirety of one major outer face of the PCB is available for the placement of PCM components.
