The present disclosure relates to managing user accounts in one or more computer systems. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of storing on a client computing device a first cookie containing plaintext representations of one or more user identifications, and a second cookie containing encrypted versions of the one or more user identifications; updating the cookies in coordination with each other based on communications received from a central server system in response to actions by a user of the client computing device to log on or off of accounts managed by the computer server system; and mediating user access to data stored locally on the client computing device by using the first and second cookies and determining whether the data is associated with one of the user identifiers.
摘要:
A method and a device for controlling the drive unit of a vehicle are described, which make it possible to suppress faults during controlling. On a first level, at least one first control variable is formed for controlling at least one actuator of the drive unit. On a second level, the correct formation of the at least one first control variable on the first level is verified using at least one selected variable. The at least one first control variable for controlling the at least one actuator is influenced by the second level if the at least one selected variable assumes a predefined value or lies within a predefined range.

摘要:
A separator for the magnetic removal of magnetizable particles, consists of an application unit for the application and the transport of sample and buffer, a separating unit of plastic or glass for the removal of the magnetizable particles, and a collecting unit. The separating unit is provided with one or more electromagnets, which are able, owing to their magnetic force, to hold the magnetizable particles back in the separating unit.
摘要:
Based on a method used in a wireless communication system (for example WiMAX), wherein a possible successful transmission power (C) for detecting a transmitter by a receiver is calculated, in order to achieve a faster detection of the transmitter by the receiver, a method is proposed, wherein from the calculated transmission power (C) a permissible maximum (D) and a permissible minimum (E) transmission power are determined. At a starting time, a transmission power (G) is set, which is below the calculated transmission power (C) and above the determined permissible minimum transmission power (E). The transmission power is then increased incrementally (F) until the determined permissible maximum transmission power (D) is reached. Upon reaching the determined permissible maximum transmission power (D), the transmission power is then increased incrementally (F) from the determined permissible minimum transmission power (E) until the determined permissible maximum transmission power (D) is reached again and is continued, until the transmitter is detected by the receiver or until further steps are initiated.
摘要:
A continuously variable transmission with two conical disk pairs on the input side and two conical disk pairs on the output-side that are connected with each another by two parallel endless torque-transmitting members in a drive mechanism. In one form of the transmission an asymmetrical cone angle on the conical disks enables the installation space to be reduced.

摘要:
A system for controlling and/or monitoring a control-unit group having at least two control units, a first control unit and at least one second control unit, the first control unit being designed for performing its control function and for monitoring this control function, as well as for monitoring the control function of the at least one second control unit.
