Torque demand is coordinated in a vehicle. Information defining at least one torque production limitation for a first torque producing device is received. A request for torque is compared with the first torque producing device torque production limitation. If the comparison does not result in the request for torque exceeding a limitation, a first coordinated torque request is determined as the request for torque and a null torque is determined as a second coordinated torque request. Otherwise, a first excess requested torque is determined as the difference between the request for torque and the exceeded limitation, the first coordinated torque request is determined as the exceeded limitation, and the second coordinated torque request is determined as the first excess requested torque.

A cleaning appliance includes a main body, a filter and an interlock. The main body includes an airflow generator, a separating apparatus separating dirt and dust from an airflow, and a flowpath between the separating apparatus and the airflow generator delimited by a wall. The interlock has a first part located on the filter and a second part located on the main body outside the flowpath, arranged to communicate remotely when the filter is correctly located in the pre-determined position. The interlock is arranged selectively to allow or prevent operation of the airflow generator depending upon the relative separation between the first and second parts. By providing an interlock which has first and second parts which communicate remotely, the second part located on the main body can be isolated from the airflow path so that the second part is not subject to dirt and dust carried by the airflow.

A floating type wave power generation system is characterized in that the system consists of eight sets of lever-type floating bodies and a hydraulic energy accumulation converter with the hydraulic pump function. On a floating workbench 7, eight sets of levers 2 and a floating body 1 are connected through supporting hinge bearers 10 and 11; in this way, the highly undulating displacement caused by waves can be converted to relatively lesser displacement of a piston rod 4, and the minor force that the floating body bears can be converted through the lever to the major force on the piston rod. The piston rod drives a hydraulic tank 3 to switch and transmit the hydraulic energy through a connecting oil pipe5, a high-pressure oil pipe6, a hydraulic oil tank and four no-return valves of each set to a hydraulic motor in a hydraulic power generation control chamber 9; in this way the generator is driven to work. The present system can absorb, convert and accumulate the intermittent unstable wave energy in a highly effective way and can buffer the destructive effect of waves. The floating platform can be suitable to different marine space by adjusting the length of an anchor chain 8. And in various sea conditions, kinetic energy and potential energy possessed by waves in the sea surface can be converted and accumulated as hydraulic mechanical energy by utilization of the wave drop; thus the generator is driven to unremittingly provide electric power.

A method and apparatus for accurately determining TTX: in a cylinder of an internal combustion engine. Gas pressure is measured in the cylinder relative to crank angle, giving rise to a curve of gas pressure with crank angle. An offset is found by first computing the angular position of an inflexion point of the compression pressure curve measured as a function of the crank angle, and then computing the offset as the difference between the angular position of a piston in the cylinder and a theoretical value for said angular position of the piston dependent on a known or measured flywheel angle. The value of TDC corrected by the offset is then used to calculate a value of work output such as the indicated Mean Effective Pressure (IMEP) which may be used for diagnostic and/or control purposes.
