  • Publication number: 20250085105
    Abstract: The present disclosure discloses a device (100) for determining orientation of an object (200). The device (100) comprises an enclosure (101). A plurality of light sources and a plurality of projection members are positioned around the enclosure (101). Further, the device (100) comprises a light source fixed about the enclosure (101), and an obstacle (103) provided within the enclosure (101). The obstacle (103) is configured to displace within the enclosure (101), pointing towards an uppermost position due to buoyant force of the fluid (106), and thus blocks impingement of light on to corresponding one or more projection members (102). The portions of the plurality of projection members (102) on which a shadow is cast, is captured by one or more image capturing units (108) to generate corresponding images, which is received by a computing unit (107) to determine orientation of the object.

  • Publication number: 20240310405
    Abstract: The present disclosure includes an accelerometer for determining acceleration of an object. The accelerometer includes an enclosure and an armature. The armature includes a hub and a plurality of arms, each defined with at least one roller at a free end. The roller contacts an inner surface of the enclosure, and at least one arm has an opaque roller.

  • Patent number: 11898876
    Abstract: 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.
