The seventh shaft is connected to the ring gear of the second set and with the sun of the fourth set, and the drive shaft is connected to the sun of the second set and to the carrier of the third set. The sixth shaft is connected to the ring gear of the first set, the carrier of the second set and the sun gear of the third set. The ring gear of the fourth set is connected to the fifth shaft which can be coupled to the housing via the third brake.

A multi speed transmission comprising planetary gearsets (P1, P2, P3, P4), shafts and shift elements. The sun gear of gearset (P1) couples shaft (4) which can couple housing (G) via brake (04) and the carrier of set (P1) couples shaft (3) which can couple housing (G), via brake (03), and drive shaft (1) via clutch (13), and shaft (6) via clutch (36). Shaft (6) couples the ring gear of gearset (P2) and the sun gears of gearsets (P3, P4). Shaft (1) couples the sun gear of gearset (P2) and is operatively connected to the carrier of gearset (P3). Shaft (7) couples the ring gear of set (P1) and the carrier of gearset (P2). The ring gear of gearset (P4) couples shaft (5) which can couple housing (G) via brake (05) and output shaft (2) operatively couples the carrier of gearset (P4) and the ring gear of gearset (P3).

A method includes, in a network, representing a first request from a first user as a first ClientUser, assigning the first ClientUser to a ServerSession, the ServerSession having one or more ClientSessions, each of the ClientSessions allowing a server to have a single session for all first user requests from the server. The method includes, in a client/server network, providing a session that can be common to all connections to a web server by a user.
摘要:
In an electromagnetically actuatable device, an electromagnet is driven with a controlled current progression so that the armature of the electromagnet can be actuated at the lowest possible current level while still achieving the most rapid overall increase of the actuating current from zero to maximum amperage. A first portion or range of the current increase is carried out with a steep or jump-like current increasing characteristic. A second portion or range of the current increase is carried out with a more gradual variation of the current. The current levels at the end points of the respective ranges are selected to ensure that the electromagnet is actuated during the second range in which the current varies more gradually. Preferably, two steep or jump-like current increase ranges are respectively provided before and after the second range having the gradual current increase. The armature of the electromagnet is thereby actuated with the lowest possible energy, and the lowest possible acceleration, so that noise and wear are reduced.

A parallel shift transmission of a motor vehicle comprising splitter and range groups. At least the splitter group is split into two parallel transmission branches having countershafts. One branch can be actuated by a power-shift element to transfer rotation of a drive shaft to a countershaft, via a stepped transmission ratio of the splitter group according to the actuation of one of the transmission branches and then converting and transmitting the rotation, via one of a plurality of range transmission ratios of the range group, to an output shaft. In order to reverse rotation, parallel countershafts can be coupled by individual gearwheel pairs by actuation of associated switching elements such that one countershaft, at the output side of the splitter group in the flow of power flow from the drive to the output shaft, is connected to the other countershaft at a drive side of the range group.

A method, implemented at least in part by a computing device, for provisioning multilingual content, may include receiving by the computing device, a selection of a language-agnostic artefact, the language-agnostic artefact including programming code for displaying a user interface with a text field. An input string designating at least a portion of a text label associated with the text field may be received. A multilingual artefact may be retrieved based on the received input string, from a plurality of available multilingual artefacts. The retrieved multilingual artefact may include a plurality of translations of the input string into a plurality of human languages. An association record identifying an association between the language-agnostic artefact and the multilingual artefact may be created.
摘要:
A drive engages a shaft (4) and, via at least one shaft (5, 6) of a transmission, an electric machine. An output can be connected to another shaft (9). During gear shifts, the shafts (4, 5, 6, 9) are couple such that the rotational speed of the shaft (5, 6), which can couple the electric machine when torque at the shaft (9) is equivalent to the torque of the electric machine, and is a product of the gear ratio between the shaft (5, 6) and the shaft (9) and the rotational speed of the shaft (9) or, when torque present at the shaft (9), is equal to the torque of the drive engine or electric machine, and is a sum of the product of the rotational speed of the shaft (4) and a first variable, and the product of the rotational speed of the shaft (9) and a second variable.
摘要:
A piezo valve is actuated by way of at least one actuator which is formed by a piezoelectric bender transducer (12) having two piezo actuators (14, 16). An actuating method has the steps of generating an actuator control signal (out), which can be output at either one of the two piezo actuators (14, 16), depending on at least one actuating control signal (in), of detecting an electric measurement quantity at one of the piezo actuators (14, 16) which is currently not controlled (16), and of generating a vibration damping signal (fb) on the basis of the detected measurement quantity and use thereof for active vibration damping for the currently controlled piezo actuator (14).
