Abstract: Systems and devices for a ring wearable cover with deformable circumference are described. The removable cover for a wearable ring device may include a ring-shaped surface and one or more mechanical features integrated into the ring-shaped surface and configured to transition between an open state and a closed state. In the closed state, the ring-shaped surface may be configured to extend around a full circumference of the wearable ring device. In some cases, a diameter of the removable cover in the open state is greater than a diameter of the removable cover in the closed state, and the diameter of the removable cover in the closed state is sized to form an interference fit with a surface of the wearable ring device to lock the removable cover onto the wearable ring device when the removable cover is in the closed state.

Abstract: Methods, systems, and devices for a functional cover are described. A removable cover (e.g., a functional cover) for a wearable ring device (e.g., a ring wearable) may include one or more electrical components positioned at least partially within the removable cover. The removable cover may further include a first electrical component exposed to an external surface of the removable cover, the first electrical component configured to contact (e.g., physical and electrically contact) a second electrical component of the wearable ring device, such as when the removable cover is in a mounted state on the wearable ring device. The first electrical component may be further configured to transfer electrical current, data, or both, between the one or more electrical components of the removable cover and one or more additional electrical components of the wearable ring device.

Abstract: Systems and devices for a ring wearable cover with non-deformable circumference are described. The removable cover for a wearable ring device may include a ring-shaped surface configured to extend around a full circumference of the wearable ring device when the removable cover is in a mounted state on the wearable ring device and one or more mounting features that are disposed on the ring-shaped surface. The one or more mounting features may be configured to interact with a surface of the wearable ring device to lock the removable cover onto the wearable ring device when the removable cover is in the mounted state on the wearable ring device. In some cases, a diameter of the removable cover is unchanged while the removable cover transitions from the mounted state on the wearable ring device to an unmounted state off of the wearable ring device.

Abstract: Methods, systems, and devices for a functional cover are described. A removable cover (e.g., a functional cover) for a wearable ring device (e.g., a ring wearable) may include one or more electrical components positioned at least partially within the removable cover. In some cases, the functional cover may wireless connect with the ring wearable. The removable cover may further include a first inductive component within the removable cover, where the first inductive component is configured to wirelessly communicate with a second inductive component of the wearable ring device when the removable cover is in a mounted state on the wearable ring device. The first inductive component of the removable cover may be configured to transfer electrical current, data, or both, between the one or more electrical components of the removable cover and one or more additional electrical components of the wearable ring device.

Abstract: Methods, systems, and devices for wearable devices are described. A wearable device may include a first annular member forming the frame of the wearable device. The first annular member may include one or more deformable features that are configured to structurally weaken the frame of the wearable device and the one or more deformable features may be located along a portion of the frame. In some cases, the wearable device may include a first annular member and a second annular member to form a frame of the wearable device. The second annular member may include a non-metal material. The first annular member, the second annular member, or both, may include one or more deformable features that are configured to structurally weaken the frame of the wearable device and the one or more deformable features may be located along a portion of the frame.

Abstract: Systems and methods for calibrating sensors of a robot are disclosed. In one exemplary implementation, an environment comprising a plurality of sensor targets and a fixed position for a robot allows for faster, more accurate calibration of a robot's sensors.
