    摘要: A high speed and low power method to control and switch the magnetization direction and/or helicity of a magnetic region in a magnetic device for memory cells using spin polarized electrical current. The mapetic device comprises a reference magnetic layer with a fixed magnetic helicity and/or magnetization direction and a free magnetic layer with a changeable magnetic helicity and/or magnetization direction. The fixed magnetic layer and the free magnetic layer are preferably separated by a non-magnetic layer. The fixed and free magnetic layers may have magnetization directions at a substantially nonzero angle relative to the layer normal. A current can be applied to the device to induce a torque that alters the magnetic state of the device so that it can act as a magnetic memory for writing information. The resistance, which depends on the magnetic state of the device, is measured to read out the information stored in the device.

    摘要: A method and system for controlling the provisioning of a device with information for accessing services of a wireless service provider via a wireless network is provided. The provisioning system initially stores automatic provisioning information on the device that includes the identification of wireless service providers that have the capability to automatically provision the device. When a user of the device wants to subscribe to a service of a service provider, the provisioning system requests an automatic provisioning service of the service provider to provide information describing available services and information needed to subscribe to those services. When the user selects a service and provides the needed information, the provisioning system retrieves provisioning information for the selected service from the service provider. The provisioning system stores the provisioning information on the device so that the device can then be used to access the selected service of the service provider.

    摘要: The invention relates to a process for the preparation of (bis)acylphosphanes of formula I, wherein n and m are each independently of the other 1 or 2; R1 if n=1, is e.g. unsubstituted or substituted C1-C18alkyl or C2-C18alkenyl, or phenyl, R1 if n=2, is e.g. a divalent radical of the monovalent radical defined above; R2 is e.g. C1-C18alkyl, C3-C12cycloalkyl, C2-C18alkenyl, mesityl, phenyl, naphthyl; R3 is one of the radicals defined under R1; the process comprises the steps a) contacting e.g. elemental phosphorous [P]∞, P(Hal)3 with a reducing metal optionally in the presence of a catalyst or an activator in a solvent to obtain metal phosphides Me3P or Me′3P2, wherein Me is an alkali metal and Me′ is an earth alkali metal or to obtain metal polyphosphides b) optionally adding a proton source, optionally in the presence of a catalyst or an activator to obtain metal dihydrogen phosphides MePH2; c) subsequent acylation reaction with m acid halides of formula III or m carboxylic acid esters of formula IV or, in case that in formula I m=1, with one carboxylic ester of formula IV followed by one acid halide of formula III or vice versa, wherein R is the residue of an alcohol and R2 is as defined above; d) alkylation reaction subsequent reaction with an electrophilic agent R1Hal or other electrophilic agents to obtain the compounds of formula I. An oxidation step may follow to obtain mono- and bisacylphosphane oxides or mono- and bisacylphosphane sulfides, which are used as photoinitiators.
