Abstract: A control system controls movement of a work implement of a work vehicle and includes a pump, a first actuator in fluid communication with the pump, a first control valve fluidly positioned between the pump and the first actuator, a first proportional relief valve fluidly positioned between the pump and the first actuator, a second actuator in fluid communication with the pump, a second control valve fluidly positioned between the pump and the second actuator, and a second proportional relief valve fluidly positioned between the pump and the second actuator. The first proportional relief valve permits flow of fluid from the first actuator upon an impact at a first set force. The first set force is adjusted by a user. The second proportional relief valve permits egress of fluid from the second actuator upon an impact at a second set force. The second set force is adjusted by a user.

Abstract: A modular head engaging assembly for use with a golf swing training device, the assembly including a U-shaped back-of-the-head positioning element including axially aligned inner and outer coupling pieces, the U-shaped back-of-the-head positioning element extending from a position adjacent the forehead of a golfer across the top of the head to a position overlying a portion of the rear of the head, a U-shaped collar element including axially aligned inner and outer coupling pieces, the U-shaped collar element being extending from a position adjacent the forehead of the golfer around each side of the head with a free end positioned above each of the ears, and a front head-positioning element including an inner coupling piece, the front head-positioning element being positioned adjacent the forehead. The three elements being coupled by the coupling pieces.

Abstract: A gantry assembly for use in an additive manufacturing system, the gantry assembly comprising a first bearing shaft, a carriage slidably engaged with the first bearing shaft, and a second bearing shaft operably supported by the carriage, the second linear bearing extending along a second axis. The gantry assembly also comprises a tool-head mount slidably engaged with the second linear bearing, a drive belt secured to the tool-head mount, a first motor having a first drive shaft engaged with the drive belt, and a second motor having a second drive shaft engaged with the drive belt.

Abstract: A system for creating an augmented reality display coupled with a firefighter's self-contained breathing apparatus (SCBA) mask. The invention combines a camera, motion tracking sensor, head-mounted display, SCBA mask, and optional head phones into a display suitable for performing exercises, such as training of firefighters or other emergency first responders, in augmented reality.

Abstract: A mobile printer having features particularly suited for use in a mobile conveyance such as an airplane. The printer stores a first data set in a memory that is accessed under control of a programmable controller. The printer then receives a second data set via a communications transceiver. Data from the first and second data sets are combined to form a composite bit mapped image which is printed by means of a thermal printhead controlled by the programmable controller.

Abstract: A position sensing system and method of use in conjunction with a rail car mounted plow burying a cable adjacent the track. The plow is arranged for cutting a kerf in the ground and for inserting the cable therein as the car moves down the track. The plow is mounted on an articulated arm including plural sections which are movable with respect to one another to position the plow at any desired location adjacent the track to cut the kerf and place the cable therein. The position sensing system includes plural transducers including transmitter and receiver sections located with respect to the arm sections to provide signals indicative of the arm section positions with respect to one another and to the ground. The system also includes transducers for providing signals indicative of the position of the plow along the track and signals indicative of the amount of cable dispensed.

Abstract: The device comprises a box, a pencil-holder with a magnet, for sliding on the box, a carriage in the box, with a magnet, and means for moving the carriage for displacing the pencil-holder through the magnets. A drawing support is placed on the box, so that a pencil in the pencil-holder can draw a pattern on the support as the carriage is moved.

Abstract: A system for determining the location of the sinking of a vessel by providing a seaworthy box that is automatically ejected from the vessel at the time of sinking and that has a battery aboard the box for powering a radio transmitter that sends distress signals that enable a rescue vessel to locate the ejected box. The system employs a water-activated release mechanism and a stationary box with which the ejected box mates. When the release mechanism operates the box is ejected and at the same time the radio transmission commences. The release mechanism can also be used to release life savers and life boats. The ejected box has a printing system for registering any faults that may have occurred prior to sinking. The vessel may be provided with fire detectors, for example, and operation of a detector is registered along with the time of detector operation to thus provide a chronological log of all important events.

Abstract: The invention concerns a device for recording and reading the itinerary travelled through by a vehicle and in particular an automobile vehicle such as an agricultural machine. The device is adapted to reproduce on an indicator band a trace of the path followed by the vehicle over a given surface so as to enable the operator to follow, with fidelity, in the course of a second passage of the vehicle, the trace of the preceding passage which permits, for example in the case of spraying, a rational treatment of the surface to be treated in strictly parallel strips with no omission or overlapping of zones. The device comprises a programmer constituted by the indicator band which travels at a speed which is proportional to the speed of the vehicle in front of a movable recording element which is controlled by the steering of the vehicle and reacts in accordance with the variations in the steering.

Abstract: This invention detects, indicates and records road surface deviations in the normally-traveled vehicle tracks. Surface deviations detectable range from less than one inch in height to the largest height negotiable by the vehicle carrying the instrument. Final measurements are indicated from a mean surface, and with proper calibration numerical values may be established to give a meaningful quantitative description of the roughness of a given section of road.Description of the surface roughness is expressed by two linear dimensions: one is the height of the encountered deviation; the other is the distance between major deviations. For analysis of the data obtained, the first dimension, the height of the deviation, is used as recorded, and the second dimension is inverted to give frequency of deviation.Measurements are made by maintaining a predetermined reference plane with a gyroscope and sensing the carrying vehicle's roll and pitch.
