Abstract: A portable data terminal generally includes a housing supporting: a data collection device: a keypad: and a touch screen. One or more PDTs are provided with a monitoring system that records occurrences experienced by the portable data terminal. The record of occurrences may be analyzed to identify errors and/or failure prone parts of the PDT along with behaviors likely to lead to errors or failures. Additionally, the record of events may be analyzed to predict errors and/or failures for any given PDT.

Abstract: A method of calculating ionospheric scintillation includes calculating a motion-corrected perturbation of a GNSS radio signal received by a monitoring device deployed in an oceanic environment. The method includes calculating the ?? using the high rate phase of the GNSS signal adjusted by removing the change in distance between the monitoring device and the GNSS satellite. The calculating the ?o may further include passing the adjusted high rate phase through a high pass filter to remove a drift motion of the monitoring device. The method further includes calculating the S4 through calculating a tilt angle between the antenna of the monitoring device with the GNSS satellite and adjusting the antenna gain through known gain pattern of the antenna. The wave height of the oceanic environment may be calculated by detrending the antenna height to remove low frequency motion when a high rate position of the monitoring device is calculated.

Abstract: A method for charging electric vehicles includes receiving information regarding an electric vehicle.

Abstract: A method and structure for a phased-array system. An orthogonal signal generator generates a plurality of signals C(i) that are orthogonal or near-orthogonal, meaning that a cross correlation between any two signals C(i) is lower than autocorrelation, and there is a plurality of phased-array antenna elements, each said antenna element providing a signal Sinp(i). A multiplier multiplies each signal C(i) with the signal Sinp(i) of a corresponding one of the plurality of phased array antenna elements.

Abstract: A work vehicle, such as a motor grader, comprises a frame, a ripper, a tie bar attached to the frame, and a four-bar linkage attached to and disposed between the ripper and the tie bar for transferring a load between the ripper and the frame via the four-bar linkage and the tie bar. The four-bar linkage and the tie bar are co-planar with respect to a plane within which the four-bar linkage is movable relative to the frame. A toolbar for the ripper is also disclosed.
