The invention relates to a system (1) for analyzing an energy efficiency of a motor vehicle (2), having: a first device (4a, 4b), in particular a sensor, configured to detect a first data set of at least one first parameter, which is suitable to characterize energy consumed by at least one apparatus A, in particular a steering system or drive device (3); a second device (5a, 5b, 5c, 5d), in particular a sensor, configured to detect a second data set of at least one second parameter, which is suitable to characterize an operating state of the at least one apparatus A; a third device (6), configured to detect a third data set of at least one third parameter, which is suitable to characterize at least one driving state of the vehicle (2); a first comparison device (7), in particular part of a data processing device, configured to compare the values of the second data set with predefined parameter ranges which correspond to at least one operating state, and to compare the values of the third data set with predefined parameter ranges which correspond to at least one driving state; an allocation device (8), in particular part of the data-processing device, configured to allocate the values of the first data set and the values of the second data set to the respectively present at least one driving state; and a processing device (9), in particular part of the data-processing device, configured to determine at least one first characteristic value which characterizes at least the energy efficiency of the at least one apparatus A on the basis of the first data set and the second data set as a function of the at least one driving state.

There is provided an arrangement for testing vehicle components, the arrangement including a test system and at least one test chamber for components to be tested. The arrangement includes an infra structure module including a transportable container for accommodating test system equipment, and at least two test modules that each include a transportable container including the test chamber for the vehicle components to be tested. The Infra structure module is between the test modules. The arrangement further includes a test system connection element for operatively connecting the test system equipment at the infra structure module to the test module.

A tool for validation of a system for monitoring at least one piece of equipment in an aircraft engine, also comprising a computer configured to: collect observation data related to the equipment, calculate a current value of at least one quality indicator on a current quantity of observation data, estimate the probability that the current value of the quality indicator reaches a predetermined reliability criterion, thus forming a probabilistic reliability law, and estimate a minimum quantity of observation data from the probabilistic reliability law, starting from which the value of the quality indicator reaches a predetermined reliability criterion with a probability exceeding a predetermined value.

A state information display for a wheel-type working vehicle includes: a state information displaying unit that displays plural kinds of state information of the wheel-type working vehicle; and a display controller that controls display of the state information displaying unit. The display controller includes: a standard screen displaying unit that displays the plural kinds of state information in the form of a standard screen during an operation of the wheel-type working vehicle; a maintenance/inspection screen switching unit that switches from the standard screen to a maintenance/inspection screen for the wheel-type working vehicle to be displayed in response to a predetermined dedicated operation; and a speed information displaying unit that displays speed information of the wheel-type working vehicle in any one of areas defined in the maintenance/inspection screen when the maintenance/inspection screen is switched to be displayed by the maintenance/inspection screen switching unit.

A method and system for maintaining stability of a system of a fuel cell vehicle are provided to prevent malfunction of sensors of a low voltage DC-DC converter and the respective controllers. A start timing of a fault diagnosis for the low voltage DC-DC converter and the respective controllers is determined and a deviation between voltages of the sensors of the low voltage DC-DC converter and the respective controllers is detected to determine whether the low voltage DC-DC converter and the respective controllers fail.

System and methods for servicing and monitoring shock struts are provided. A shock strut servicing assistance system may comprise: a controller in electronic communication with a display; and a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising: calculating, by the controller, a dead volume of a shock strut and determining, by the controller, a first decision, the first decision being whether or not the dead volume of the shock strut is negative. A shock strut servicing assistance system may be for servicing a shock strut having a negative dead volume.

A failsafe pin for providing a backup load path for attaching a gas turbine engine to an aircraft structure is provided with a driving element that allows a torque to be provided to the pin in order to check whether the pin has been engaged, and thus whether a primary load path has failed. The pin is provided with anti-tamper arrangements in order to ensure that the pin itself is not compromised when being tested for engagement.
