Abstract: An apparatus for distributed correlation of RF information includes a radio having an RF transceiver and sensor in communication with the radio. The sensor has a collector for extracting signal data from the radio and a correlator for correlating the extracted signal data with sensor correlation data stored within a database within the sensor to detect an anomaly in the extracted signal data. When an anomaly is detected in the extracted signal data, a computerized service processing device receives the correlated extracted signal data from the sensor and executes one or more of an alert process to alert a user of the detected anomalies and an updating process to a correlation sub-system within the computerized service processing device, where the detected anomaly is curated and transmitted to the database of the sensor device to update the sensor correlation data stored therein.

Abstract: A motion-control system includes an operator interface with an operator-input member and a controllable force feedback device drivingly connected to the operator-input member. The motion-control system may also include controls that regulate the motion of one or more moveable components, including adjusting a first operating parameter in a manner that depends at least in part on a control error between a target value of a second operating parameter and an actual value of the second operating parameter. The target value of the second operating parameter may be based at least in part on the motion of the operator-input member. The controls may also operate the controllable force feedback device to provide feedback force on the operator-input member in a manner that depends at least in part on the control error and such that the derivative of the feedback force with respect to the control error varies dependent at least in part on the control error.

Abstract: A fan speed control system for a machine is disclosed. The control system may include a fan to provide a flow of coolant to the machine. The system may further include a first sensor configured to generate a first signal indicative of an operational parameter of the machine, a second sensor associated with the fan to generate a second signal indicative of an actual speed of the fan, and a controller communicatively coupled to the fan, the first sensor, and the second sensor. The controller may be configured to generate a third signal indicative of a desired fan speed based on the first signal, and a fourth signal indicative of a difference between the desired fan speed and the actual fan speed. The controller may drive the fan based on the third signal and the fourth signal.

Abstract: A method to integrate engine and exhaust aftertreatment control may include connecting an engine controller to an aftertreatment controller using a common data link protocol to provide a bidirectional data flow between the engine controller and the aftertreatment controller. The method may also include connecting the engine controller to one or more engine components. The method may also include connecting the aftertreatment controller to one or more aftertreatment components.

Abstract: A radio receiver for receiving signals of at least two different communication standards, including a narrow band signal having a narrow bandwidth and a wide band signal having a wide bandwidth, is provided. The receiver comprises a shared radio frequency (RF) front-end that receives the wide band signal during at least one period of operation, downconverts, in a single downconversion, the wide band signal directly to baseband, receives the narrow band signal during at least another period of operation, and downconverts, in a single downconversion, the narrow band signal to a low intermediate frequency (Low-IF). The receiver further comprises a baseband processing chain that operates on the downconverted wide band signal to extract desired data and a Low-IF processing chain that operates on the downconverted narrow band signal to extract desired data.
