Abstract: In order to reliably detect a jamming situation, in particular in a seat adjusting means, provision is made for a total loading exerted by the drive during a start phase to be determined and for this to be fixed as the basic loading. The existence or non-existence of a jamming situation is finally determined during a monitoring phase by comparing the basic loading and the total loading that varies during operation of the adjusting apparatus.

Abstract: The invention relates to a turbine wheel (7) for a gas operated medical, in particular dental-medical, handpiece (3), having a plurality of blades (2) which extend in radial direction from a hub (7c) and extend in axial direction from a side ring web (29) of the turbine wheel (7), and the front side (22a) of which is substantially concavely curved about an approximately radially running first axis of curvature (23). In order to increase the drive power or to better exploit the drive power the rear side (22b) of the blades (22) has at least in an axial end region an inclination surface (35) which is inclined in the axial direction towards the front side (22a).

Abstract: Lumbar support and control device of a lumbar support and method for controlling a lumbar support of a motor vehicle. An electric control device is provided for a lumbar support which has a drive coupled mechanically to an adjusting mechanism for setting the seat contour of the lumbar support. The control device has at least one computer unit which controls a massaging movement of the lumbar support whereby the massaging movement is characterized through several predefinable ideal speeds. Several ideal speeds for one or more adjusting directions of the lumbar support are controllable through the computer unit. For control by the ideal speeds a drive moment of the drive is adapted to an actual load of the drive so that the massaging movement can be controlled substantially independent of the actual time-changeable or locally variable load. The drive moment is consequently changeable through the control device.

Abstract: A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction. In some operations, software creates, updates, or otherwise processes information related to a freight order, a maintenance plan, a maintenance task list, a request for supplier freight quote, and/or a supplier freight quote business object.

Abstract: In order to draw a reliable conclusion about the existence of a jamming situation, in particular in a seat adjusting means, provision is made to distinguish between the following movement classes: a) running difficulty of the adjusting apparatus, b) jamming of an object, c) encountering an end stop, and d) sudden counter-reaction, with a decision criterion (c, c1, c2, M3) being derived from detected characteristic variables (u, i, n) of a motorized drive (2), and the current state of the adjusting apparatus being associated with one of the movement classes on the basis of said decision criterion.

Abstract: Methods and apparatuses enable creating a stateful simulation process with stateless messages. A stateless message instantiates a simulation object for a system to be simulated. The simulation object is identified by an identifier. Activity request messages, which are stateless, identify the simulation object identifier and can thus be associated with the simulation object. Results of execution of requested activities are stored in the simulation object, and thus persisted in the simulation object. In one embodiment, the persisting of simulation results in the simulation object allows the simulation data to be isolated from the active system data. In one embodiment, results of the execution of the simulation are merged in whole or in part with the active backend data.

Abstract: A method for controlling a vehicle seat adjuster in an adjusting path having a first mechanical stop and a second mechanical stop. A user sets an adjustment position of the adjuster inside the adjusting path. A protective stop is also automatically set in the adjusting path in the vicinity of the mechanical stops or another mechanical block blocking the adjusting path. The protective stop causes the adjusting motion to be reduced or stopped upon reaching of the protective stop. This helps produce a smooth braking of the vehicle seat and reduces the mechanical strain on the mechanical stops. The protective stop may be corrected with an updated protective stop. The updated protective stop is maintained despite any user action if a condition dependent on the adjusting motion of the adjuster is fulfilled. Learning regions within the adjusting path are provided to allow the setting of updated protective stops within the learning regions.

The sensor employs an active electrode; a passive electrode; and an electrolyte in contact with both electrodes. The electrolyte is disposed on a substrate and a heater is located in thermal contact with the substrate for heating the substrate and the electrolyte.
