The present disclosure discloses a device (100) for determining orientation of an object. The device includes a hollow spherical member (101), which is filled with a fluid medium (109). A plurality of sensors (102) is positioned on a circumference of the hollow spherical member. Further, the device comprises a light source (104) fixed within the hollow spherical member, and a capsule (103) is disposed within the hollow spherical member. The capsule is configured to displace within the hollow spherical member and occupy uppermost point of the hollow spherical member. The capsule covers the one or more sensors at the corresponding uppermost point and, thus blocks impingement of light on to corresponding one or more sensors. The blocked one or more sensors activate or deactivate, and generate a feedback or input signal, which is received by a computing unit (107), to determine orientation of the object.

A level includes a frame having a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface. The top planar surface and the bottom planar surface are parallel. The level further includes a vial supported by the frame. The vial has a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble. The level further includes a plurality of LEDs. Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.

An electro-optical level employs a bubble tube with opposite first and second ends. First and second light emitters are disposed respectively beyond the first and second axial ends of the tube and direct light toward the ends of the bubble in the tube. Electro-optical detectors are aligned substantially parallel to the axis of the tube and are spaced from the tube. First and second beams from the respective first and second light emitters scatter as the beams impinge upon the bubble. However, the scattered light from each light emitter will form a bright spot on the respective electro-optical detector at a point corresponding to the end of the bubble. The locations of the bright spots are detected by the electro-optical detectors and precisely determine the locations of the opposite ends of the bubble regardless of dimensional changes of the tube or the bubble due to temperature variations.

A vehicle safety device for detecting vehicle tilt automatically shuts-off power to an ignition system and fuel pump and summons emergency assistance using a bistable switch circuit that toggles between a first bistable switch position in response to a reset signal and a second bistable switch position in response to an alert signal. The safety device can remain in the bistable switch positions without a power source and employ an encrypted bi-directional protocol to summon emergency assistance and generate the reset signal without vehicle operator intervention.
