Existing and future standardized VDSL2 and other systems can be integrated into and used with a vectored DSLAM or other vectored or non-vectored DSL system, without a new user disrupting service to other users in the same or a nearby binder, in some cases by using transmit power, CARMASK and/or PSDMASK DSL capabilities to reduce both downstream and upstream training-signal levels so that training of a new DSL line is non-disruptive, despite a lack of knowledge of the pre-existing binder. For vectored systems, the crosstalk from that tone can be observed, learned and then added to the vectoring system so that any subsequent excitation on that tone would be eliminated by vector processing. A second tone then can be added in the same way, etc. In non-vectored DSLs that might be operating in a binder or line set, once these non-vectored lines are observed to be present, a vectored line set controller, such as a DSL optimizer, then can anticipate the potential interference from such non-vectored lines.

A portable electronic device can detect whether an output unit of an accessory is connected to the body of a user and determines audio output units to which its application will transmit audio signal. The portable electronic device comprises an interface connected to the accessory, an application handling unit and a control unit. The control unit determines if the accessory is attached to the body of a user, selects audio output units to be used for the electronic device and transmits audio signals to the selected audio output unit for the application.

A power subsystem for a computer system allows a voltage regulator module (VRM) to be removably connected to a system board, while limiting disturbances on the voltage rails of the system board. The electrical disturbances are prevented by charging voltage outputs of the DC/DC circuit of the VRM prior to directly connecting the voltage outputs to the voltage rails. To ensure that the voltage outputs are properly charged, a VRM connector may be used in which the voltage output pins are shorter than charge pins which are coupled to respective capacitors and to the voltage outputs of the DC/DC circuit. In this manner, as the connector is mated with a corresponding connector on the system board, the capacitors are first charged via resistive paths connected to the voltage rails, prior to directly connecting the voltage outputs to the voltage rails. The VRMs are thus "hot-pluggable," enabling a user to upgrade or service the system with no interruption.

A fuel vapor treatment system which has adsorbent, a purge passage for introducing a mixture gas of air and the fuel vapor desorbed from the adsorbent into the internal combustion engine, a detection passage which communicates to the purge passage, and a pump which generates gas flow so that the mixture gas flows into the detection passage from the purge passage. A pressure sensor detects fuel vapor concentration. An ECU and a purge control valve controls a purge of the mixture gas from the purge passage to the internal combustion engine based on a reference concentration of the fuel vapor. The ECU establishes the detection interval of the fuel vapor concentration in consideration of change in reference concentration.

A method of determining output power in a first restricted local access point in a wireless network, a device implementing a restricted local access point, a wireless network as well as a computer program product for determining output power in a restricted local access point. A restricted local access point scans the network for determining broadcasting channels used by surrounding access points, selects a broadcasting channel that receives the lowest disturbance by surrounding access points, varies the output power of this channel for obtaining a desired relation to the disturbance and determines if a main disturbing access point is another restricted local access point. If it is, a threshold is set for one of the quantities of the relation, which the quantity is not allowed to pass, the output power is varied for providing the desired relation without said quantity passing said threshold and otherwise another channel is selected.
