A tilt indicator includes a housing having a face member and a back member. A movable mass member is disposed within the housing between the face member and the back member. A first encoded indicium is disposed on the mass member, and a second encoded indicium is located on the back member. In response to the tilt indicator being subjected to a tilt event exceeding a threshold, the mass member moves from a first position to a second position.

A processor is operably coupled to a time of flight (TOF) camera, a light detection and ranging (LIDAR) sensor, and an optical camera. The processor can receive a TOF signal representative of a first coordinate associated with a stick-up height of a tool joint of a pipe of a drill string during a tripping operation on a rig drill floor, and a pitch and a roll of the tool joint. The processor can receive a LIDAR signal representative of a second coordinate associated with the stick-up height, and the pitch of the tool joint. The processor can receive an optical camera signal representative of a third coordinate associated with the stick-up height of the tool joint and the roll of the tool joint. The processor can generate a pose estimate and an orientation estimate based on the signals.

An Electronic Conduit Bending Indicator, Level, and Environmental Data Display is disclosed. It easily inserts directly into the opening of conduit or pipe bender, allowing the user to have the display within easy viewing distance. The conduit bending indicator displays actual and relative angles from the horizontal plane on the Y-axis and functions as a spirit level on the X-axis. It has a 4-way level for measuring the X and Y axes with relative and actual angular display and data-hold, and a protractor function allows relative angular measurements when rotated horizontally. The invention also displays the dry-bulb, wet-bulb, and dew-point temperatures, OSHA heat-index (sunny and shady), enthalpy (sensible, latent, and Qs/Qt), saturated and actual vapor pressure, relative humidity, absolute humidity, humidity ratio, vapor pressure, cubic feet per pound of dry air, atmospheric pressure, altitude, vapor deficit, vapor density, and partial, actual, and dry air densities. This data may be read from the environment or calculated.

An apparatus for detecting tilt of a fixture and method thereof. The apparatus includes a visible element having a pattern visibly distinguishable from its surrounding area; a part having a plane reflective surface being configured to be engaged with the fixture in alignment and being arranged to reflect light beams propagating directly from the visible element so as to produce a first virtual image of the visible element; an image capture device being disposed at same side of the visible element with respective to the part having a plane reflective surface and being configured to have a field of view covering the first virtual image and a second virtual image of the visible element produced by the part having a plane reflective surface, wherein the second virtual image was produced where the part having a plane reflective surface assumed a levelling orientation; and a controller being adapted for detecting tilt of the fixture using a deviation of the first virtual image from the second virtual image of the visible element in the field of view of the image capture device. By using the apparatus or method according to present invention, no optical means, such as lens, is used for converging the light beams projected by the visible element. It is thus possible to facilitate the assembly of the apparatus, miniaturize the apparatus and reduce costs thereof.
