A system and method for generating a navigation solution in high interference and dynamic environments using Global Positioning System (GPS) and inertial measurement unit (IMU) data is described. The system configuration is a multi-satellite tracking loop structure obtained by closing each satellite's tracking loop through a single, multi-state navigation filter. This generates a robust navigation solution that can track GPS signals in a lower signal to noise ratio than can the standard GPS tightly coupled tracking loops. The system contains an Advanced Tightly Coupled (ATC) tracking processor which accepts early, late, and on-time I and Q data from the GPS signal tracker and outputs vehicle to satellite range, range rate and range acceleration residual measurements to a navigation Kalman filter. The ATC includes nonlinear discriminators which transform I and Q data into linear residual measurements corrupted by unbiased, additive, and white noise. It also includes an amplitude estimator configured to operate in rapidly changing, high power noise; a measurement noise variance estimator; and a linear residual smoothing filter for input to the navigation filter.

A multivariable process controller controls a chemical, polymer or other physical process. Slow tuning and over-conservative controlled variable values are employed during step testing. While all controlled process variables are within safe limits, only one manipulated variable (MV) at a time is step changed. Several manipulated variables are moved when process variables exceed safe limits to ensure that the controlled process variables return to the safe range, such that suitable MV targets for step testing are able to be automatically discovered within a closed loop control environment. Thus, the step test is able to be conducted mostly unsupervised and / or remotely via a telephone or network connection. A new process perturbation approach simultaneously perturbs multiple or all of the process input variables in such a way that the process responses (process outputs) are maximized, while the process variables are maintained inside its predefined operating constraints. It uses magnitude modulated Generalized Binary Noise (MGBN) signals to excite multiple process variables, and uses a specially designed model predictive controller (MPC) to safeguard the process. The specially designed MPC controller uses minimal move and discrete control action to reduce interference with the GBN perturbations and prevents unwanted feedback from contaminating the data quality, while keeping the process operating in a desired range.

A system and method for GPS acquisition in relatively high interference is described. Acquisition is aided by an Advanced Tightly Coupled (ATC) tracking filters that compute a satellite range residuals and range rate residuals for satellites being acquired. Multiple channels are used in parallel to search for the desired satellites. Range residuals from the ATC filters are used to correct the computed receiver offset and thus allow acquisition in the presence of relatively high interference.

In a situation where it is predicted that a symbol of target torque reverses by turns to be positive and negative alternately, the hybrid ECU carries out an increasing correction of the target torque, in which the target torque is corrected by increasing the target torque by a set amount ΔT in a negative direction when a specific condition, in which it is judged that the degree of the vertical vibration of a vehicle body is larger than a standard value and it is judged there is no acceleration demand, is satisfied, and makes the vibration suppression control torque not to be contained in the target torque when the specific condition is not satisfied. Thereby, even when carrying out free run, the sprung vibration suppression control can be carried out during bad road running, and braking force can be suppressed and fuel consumption can be improved during good road running.

A method for scanning a work piece surface uses a coordinate measurement device. A probe element is brought into contact with the surface and the probe element is moved along the surface. The coordinate measurement device has a plurality of degrees of freedom, which are independent of one another, in the possible movements of the probe element with respect to the work piece. Maximum speeds which describe the maximum of a movement speed component of the probe element based on the respective degree of freedom are defined for the degrees of freedom. An estimated path on which the probe element is intended to move during scanning is predefined. The actual scanning path can differ from the estimated scanning path. A maximum scanning speed at which the estimated scanning path can be traveled with a constant speed of the probe element is determined.

A battery driven mobile communication device drawing a base current with periodic high current pulses during transmission. The current pulses may be larger than the current level which the device's battery can supply. The device uses a switched mode power supply with an output capacitor sufficiently large to provide the high current pulses when demanded by the load, without its voltage falling below that necessary to operate the device. This power supply provides the average current drawn by the load, and maintains the capacitor's charge. When the load demands a current pulse, that excess current is drawn from the capacitor, which begins to discharge. Once each pulse is completed, the battery continues to provide the lower baseline current of the device, and at the same time tops up the capacitor to replace the charge used during the pulse. The battery may be a low cost primary battery.
