摘要： Linear Position Sensor Known linear position sensors suffer from inaccuracies owing to severe environmental conditions, such as temperature and humidity. Physical damage to sensors exposed to rugged work conditions is a limiting factor in the expected life of sensors used, for example, in the heavy equipment industry. A pair of loop antennas mounted internal to an extensible coaxial cavity respectively transmit and receive electromagnetic signals in the radio frequency range exciting a transverse electromagnetic field in the cavity when the frequency of the signal corresponds to the resonant frequency of the cavity. The resonant frequency of the cavity is primarily dependent upon the longitudinal length of the cavity. Therefore, a voltage controlled oscillator acts under the control of a sawtooth voltage waveform of a function generator to controllably deliver a variable frequency signal to the first loop antenna. An RF detector monitors the second loop antenna for an indication that the resonant frequency has been reached. At resonance a microprocessor samples the output of the VCO and correlates the resonant frequency to the length of the coaxial cavity. The sensor is particularly suited for use in the heavy equipment industry for detecting the extended length of hydraulic cylinders as it is highly insensitive to environmental conditions and protected from the work environment.

摘要： Systems and methods for executing a fluid delivery mission are disclosed. In one embodiment a mobile fluid delivery machine (106) for delivering fluid to a site (100) has a tank (200) storing fluid, and at least one spray head (202) configured to spray the stored fluid onto the site. In addition, the mobile fluid delivery machine has a communication device (318) configured to receive fluid delivery mission instructions (900) from a site computing system (112), the mission instructions identifying a sequence of path segments (902) on the site and corresponding fluid delivery amounts (904) allocated to the path segments, and a location device (324) configured to determine the location of the mobile fluid delivery machine on the site. The mobile fluid delivery machine also has a fluid delivery system (326) configured to determine whether the location of the fluid delivery machine corresponds to a path segment of the sequence, and when it is determined that the location of the fluid delivery machine corresponds to a path segment in the sequence, to identify the fluid delivery amount allocated to that path segment based on the mission instructions.

摘要： An avoidance system (40) is disclosed for operating a vehicle (38) on a pile (18) of material (16) on a worksite (10), the material (16) being released through an opening (20) at the worksite (10) and causing a disturbance zone (32) to form on a surface (30) of the pile (18). The system (40) has a sensor (42) positioned at the worksite (10) and configured to sense the surface (30) of the pile (18), and a processor (50) in communication with the sensor (42) and the vehicle (38). The processor (50) is configured to identify the disturbance zone (32) based on the sensed surface and a known location of the opening (20), and to transmit a signal indicative of the disturbance zone (32) to the vehicle (38).
