Patent number: 11898876Abstract: The present disclosure discloses a device for determining orientation of an object. The device comprises a hollow spherical member. A plurality of sensors are positioned within a cavity defined by an inner surface and an outer surface of the hollow spherical member. Further, the device comprises a light source fixed within the hollow spherical member, and a solid sphere provided within the hollow spherical member. The solid spherical member is configured to displace within the hollow spherical member, pointing towards gravity and occupies lowermost position of the hollow spherical member, and thus blocks impingement of light on to corresponding one or more sensors at the lowermost position of the hollow spherical member. The blocked one or more sensors activate or deactivate, and generate a signal, which is received by a computing unit, to determine orientation of the object.Type: GrantFiled: April 15, 2019Date of Patent: February 13, 2024Inventor: Tilak Srinivasan
