摘要： An apparatus coupled to a work machine for assisting the work machine in removing a first layer of material from a second layer of material is provided. The work machine includes a work implement with a cutting portion. The work implement is elevationally movably connected to the work machine. The cutting portion extends in a direction transverse the longitudinal axis of the work machine. An electromagnetic unit, connected to the work machine, delivers electromagnetic radiation towards the surface, receives a reflection of the delivered electromagnetic radiation, and delivers a responsive first signal. The electromagnetic radiation penetrates the first layer of material and reflects off of the second layer of material. A controller receives the first signal, determines the distance between the electromagnetic unit and the second layer of material and responsively produces a distance signal. An implement controller receives the distance signal and responsively actuates the work implement relative to the frame.

摘要： 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.
摘要翻译：已知的线性位置传感器由于恶劣的环境条件（如温度和湿度）而受到不准确的影响。暴露于恶劣工作条件下的传感器的物理损坏是使用传感器的预期寿命的一个限制因素，例如重型设备行业。安装在可扩展同轴腔内部的一对环形天线分别在射频频率范围内发射和接收激励腔内的横向电磁场的电磁信号，当信号的频率对应于空腔的谐振频率时。空腔的谐振频率主要取决于空腔的纵向长度。因此，压控振荡器在函数发生器的锯齿波电压波形的控制下起作用，以可控地将可变频率信号传送到第一环形天线。 RF检测器监测第二环形天线以获得已经达到谐振频率的指示。在谐振时，微处理器对VCO的输出进行采样，并将谐振频率与同轴腔的长度相关联。传感器特别适用于重型设备行业，用于检测液压缸的延长长度，因为它对环境条件非常不敏感，并且受到工作环境的保护。

摘要： A terrain mapping system is disclosed. The system has at least one sensor configured to gather a plurality of current points defining a current surface of a site and a database containing a plurality of previously-gathered points defining a previous surface of the site. The system also has a controller in communication with the at least one sensor. The controller is configured to compare a height of at least one of the plurality of the current points to a height of a corresponding at least one of the plurality of previously-gathered points and to determine if an update to the database is warranted based on the comparison. The controller is further configured to update the database if it is determined that an update is warranted.

摘要： An apparatus and method for directing the operations of multiple geography-altering machines on a common work site relative to one another. Position information from several machines is shared to generate a common, dynamically-updated site database showing the machines' relative positions and site progress in real time. The common site database is used to direct the operation of one machine with respect to another machine or machines, for example by generating an operator display of the site showing relative machine position and total machine work on the site. The operator can accordingly adjust the machine's operation to avoid interference with other machines or unnecessary overlap of work on the site. The information can also be used to coordinate the operations of several machines in complementary fashion. Machine position information can be broadcast from the machines to the site database to create a common, dynamically-updated database which is then shared with one or more of the machines. In a particular embodiment each machine is provided with its own dynamically-updated database and operator display, and machine position information is shared on a continuous, real-time basis between the machines so that they effectively share a common site database.

摘要： Systems and methods allow for the accurate determination of the terrestrial position of an autonomous vehicle in real time. A first position estimate of the vehicle 102 is derived from satellites of a global positioning system and/or a pseudolite(s). The pseudolite(s) may be used exclusively when the satellites are not in the view of the vehicle. A second position estimate is derived from an inertial reference unit and/or a vehicle odometer. The first and second position estimates are combined and filtered using novel techniques to derive a more accurate third position estimate of the vehicle's position. Accordingly, accurate autonomous navigation of the vehicle can be effectuated using the third position estimate.

摘要： Off-highway trucks generally rely on a suspension system which employs a plurality of gas-over-liquid type struts. These struts are critical to proper operation of the vehicle such that a single collapsed strut can have serious manifestations in structural damage, tire wear, and payload monitor accuracy. These consequences can be mitigated by an accurate and reliable strut monitor. Pressure type sensors are disposed on each of the struts and their pressure is monitored during three critical phases of operation. These phases include static, loading, and roading modes and each mode requires a distinct method for detecting a collapsing strut. The presence of a collapsing strut, detected by any of the three methods, is communicated to the vehicle operator whereby operation can be immediately suspended. The system avoids the serious consequences of vehicle operation with a collapsed strut by providing the operator with immediate and positive feedback on the condition of the struts.
