Abstract: An RV wireless remote control system comprising an HMI including a GUI coupled to an HMI RF transceiver and an HMI dock connector. The HMI RF transceiver receives RV device status signals over an RF fieldbus and the HMI dock connector receives RV device status signals over an RV localbus. The HMI generates control signals in response to the status signals and/or operator input signals. The HMI transmits the control signals to the RV devices over the RF fieldbus via the HMI RF transceiver or over the RV localbus via the HMI dock connector when the HMI dock connector is connected to the RV localbus. The HMI is configured for real time distributive control of the RV devices such that the RV localbus and the RF fieldbus operate in both directions enabling closed-loop control between the HMI and the RV devices.

Abstract: A portable carrier includes a base housing and a cover member secured to the base housing. The base housing is provided with an internal cavity defined by a bottom wall and an enclosing wall extending substantially upwardly from the bottom wall. The cover member is adapted for selectively reconfiguring the portable carrier between a first, closed position preventing access to the internal cavity and a second, open position providing access to the internal cavity. The cover member is dimensioned to closely conform an outer peripheral surface of the base housing so that in the second position the cover member is nested under the base housing over and around the outer peripheral surface thereof. The portable carrier further includes a child-resistant locking device provided for preventing the portable carrier from being open.

Abstract: An autocalibration method for use within an electronic compass in a vehicle is disclosed. The method includes steps of initializing variables and then retrieving sensor readings from at least two axis. The method then compares the compass tilt to a predetermined threshold. Next the method will determine if the sensor reading is a minimum or maximum for the current calibration cycle. Next the method will determine if the maximum value of the sensor readings is greater than the predetermined minimum spread. Then the method will calculate an offset value for each axis and calculate a sensor value for each axis. Then the method will calculate an azimuth value with the new sensor values and determine the heading using the azimuth.

Abstract: A leveling assembly for analyzing the attitude of a structure such as a motor vehicle in two axes. The assembly drives leveling devices on the structure to correct the attitude of the structure relative to a calibrated reference point or attitude. The assembly includes a controller connected to the leveling devices and a proportional two-axis tilt sensor that is connected to the controller and supported on the structure. The tilt sensor provides analog signals to the controller that represent the attitude of the structure about longitudinal pitch and lateral roll axes. The controller also uses those signals to determine the attitude of the structure relative to a calibrated sensitivity factor and a user-defined zero point. This allows an operator or installer to determine which portion of the structure will be leveled without regard to the location of the tilt sensor and allows an installer to mount the tilt sensor at any point on the structure.
