Abstract: Certain embodiments of the present disclosure provide techniques for eliminating an appearance of one or more objects in an environment surrounding a vehicle during operation of the vehicle. A method generally includes detecting the one or more objects in first sensor data collected from first sensors onboard the vehicle, wherein the first sensor data is representative of the environment surrounding the vehicle; receiving, from other vehicles, second sensor data collected from second sensors onboard the other vehicles, wherein the second sensor data is representative of the environment surrounding each of the one or more other vehicles; generating one or more augmented reality images depicting portions of the environment obstructed by the one or more objects in the first sensor data; displaying the one or more augmented reality images in an augmented reality display such that the augmented reality images are positioned to overlay the one or more objects.

Abstract: A slag transport and dumping apparatus, for use with slag, includes a vehicle, a pallet, and a lifting mechanism. The vehicle includes a bed having a pallet interface. The pallet includes a support frame having ground support members, and a transporter interface selectively engaging the pallet interface. A dump container has a slag reservoir. Rear pivots on the container and pallet, together with the lifting mechanism, which is securely mounted to the bed of the vehicle and selectively engages the container, enable secure selective pivoting of the container between slag retaining and pouring configurations. In a loading configuration, the reservoir receives the slag, the container is in the retaining configuration, and the vehicle is removed from the pallet. In a transporting configuration, the container is in the retaining configuration, and the vehicle securely engages the pallet, in carrying relation, thus enabling transport of the pallet.

Abstract: A system and method for testing an automotive electronic microcontroller includes a multi-chip module comprised of a microcontroller chip and at least one memory chip. This multi-chip module is packaged in the same connection configuration a production single chip microcontroller urgently designed for the controller. The multi-chip module, thus, replaces the single chip module on the controller board itself and provides extra memory. A PC work station may be connected to the controller board via a reserved 8-pin interface. Once development and/or testing is complete, the multi-chip module is then replaced with the single chip module.

Abstract: A radial type air-core gauge includes orthogonally positioned pairs of stator coils wound on independent coil forms spaced radially 90 degrees apart about a central cup of a gauge case. The cup houses a permanent magnet rotor which rotates about a shaft extending from a support bearing in a bottom surface of the cup to a hub of a dial pointer. Movement of the shaft causes a dial pointer to move over a dial face in response to changes of a balanced resultant field caused by variations of excitation signals applied to the stator coils.

Abstract: Automatic locking of the vehicle door locks by a relay controlled by sine and cosine voltage signals from a frequency to voltage (F/V) converter. A pulse-train signal whose pulse repetition rate varies with the speed of the vehicle is used to supply frequency information to the F/V converter.

Abstract: A fluid pressure transducer having a hollow enclosure with an elongated tubular guide supported therein around which a tubular piston moves in response to fluid pressure forces acting on one piston end. A spirally-wound wire resistance coil on the guide is contacted by one end of a conductor carried by the movable piston to effectively charge resistance through the conductor and parts of the coil. The conductor is connected to one end of a metal spring which opposes piston movement due to pressure forces. An opposite end of the metal spring is connected to a terminal to transmit the resistance changes.

Abstract: An apparatus and method for preventing damage to the mechanical components of a borehole inclinometer is disclosed. The inclinometer uses a freely suspended pendulum to align with the vertical at a selected position in the borehole. A compass connected to the pendulum rotates to an orientation defined by the earth's magnetic field. To protect the components which suspend the pendulum, the pendulum is clamped between a timer and a lens as the inclinometer is lowered into the borehole. At a selected time, the pendulum is unclamped and is permitted to reach an equilibrium, measuring position. After a selected interval, the timer urges the pendulum against the lens to clamp the pendulum. The inclinometer is raised from the wellbore, and the orientation of the pendulum relative to the lens is observed to determine the azimuth and inclination of the borehole.

Abstract: A method and apparatus for establishing the rate at which fluid is transferred between a borehole 14 and the surrounding formations 16 in the course of moving drill string 20 upward or downward in the borehole 14. A bell nipple 40 is situated at the upper portion of the borehole 14. While tripping, drilling fluid is circulated into the borehole 14 and exits through an outflow port 44 in the bell nipple 40. The level of drilling fluid is maintained constant at the outflow port 44. Meters 52, 52', 54 are provided to measure inflow and outflow rates. Circuitry 66 is provided to establish the volume rate at which the amount of drill string 20 within the borehole 14 changes. The outputs of the meters 52, 52', 54 and rate establishing means 66 are summed to establish the compensated rate at which fluid is transferred between the formations 16 and the borehole 14. This compensated rate is compared to an alarm limit. An alarm 76 is activated if the compensated rate exceeds the alarm limit.

Abstract: A liquid-projecting monitor of the spherical head type has its head sealing against a housing which defines together with the head a chamber from which liquid is lead into a passage in the head and then to a nozzle coupled to the head. The head is borne by a horizontal axle for pivotal movement relative to the housing so as to adjust the angular elevation or depression of the nozzle. A center body extends transversely across the interior of the head to enclose the axle and is so shaped, together with the internal surface of the head, that the cross-sectional area of the passage within the head available for liquid flow is maintained at least approximately constant throughout its length, so as to minimize the pressure drop in the liquid flow which passes through the head.

Abstract: A method for controlling the flow of drilling fluid through a subaqueous wellbore is disclosed. The method comprises the steps of continuously measuring the output flow rate (A) of the drilling fluid from the wellbore, the input flow rate (B) of the drilling fluid to the wellbore, and at least a component of the pitch and roll (P/R) of the vessel, computating a floating alarm limit (C) dependent upon the pitch and roll (P/R) signal and the roughness of the sea, filtering the periodic fluctuation of the output flow rate (A) due to the motion of the vessel, and computating the delta flow signal (D) by subtracting the input flow rate (B) from the filtered output flow rate (A).

Abstract: A gyro seeker which is capable of use in a cannon launched missile. The gyro seeker is enclosed in a housing mounted in the nose section of the missile. The platform of the gyro seeker supports an optical assembly, a detector, a gyro assembly, and a cryostat for cooling the detector. Means are provided on the outer gimbal of the platform for withstanding the extreme acceleration induced by cannon launching. The platform is torqueable along two axes by a plurality of pole pieces located around its base. A platform caging device is provided to cage the platform during transport and serves a dual function as a means to furnish spin-up gas to the gyro element and cooling gas to the cryostat.

Abstract: A caging mechanism for a gyro in which a flat split ring lying in a plane perpendicular to the gyro rotor spin axis is deformable so that its inside diameter is enabled to capture the gyro rotor. A gas activated piston separates tabs formed on the split ring causing it to cage or uncage the rotor.

Abstract: A rate sensor comprising a glass annulus filled with an electrolytic fluid. A plurality of electrodes in contact with the electrolyte have an electrical field established between them which in turn starts a flow of ions between the electrodes. When the device is rotated about a predetermined axis the flow of ions between certain electrodes is increased. Electronic means connected to output electrodes senses the change in ion flow and determines the rotational rate of the vehicle upon which the sensor is mounted.
