In order to determine the actuation position of a motor-driven adjusting element of a motor vehicle, a Hall-effect sensor is located in a rotatable magnetic field, wherein a periodic change in the magnetic flux density sensed by the Hall-effect sensor is converted into a binary pulse train in that a pulse transition takes place when an upper switching threshold is positively exceeded and when a lower switching threshold separated from the upper switching threshold by a hysteresis is negatively exceeded. The hysteresis is reduced following an inactive phase of the Hall-effect sensor during which the magnetic field was stationary and / or the Hall-effect sensor was deactivated, if the magnetic flux density at the start of the inactive phase has exceeded the upper switching threshold by no more than a predefined tolerance range.

The present invention relates to receiver apparatuses and methods of controlling weight adaptation in a receiver of a code multiplex telecommunications system with orthogonal spreading codes, wherein received discrete time signal samples are chip-level filtered by using a first equalising step. Additionally, the received discrete time signal samples are delayed by a time period corresponding to a data symbol and used in a second equalising step. Symbol estimates obtained from the first equalising step are non-linearly filtered and used as a desired response for the second equalising step in the following symbol period, wherein equaliser weights adapted in the second equalising step are used for the first equalising step. Alternatively, the second equalising step may be dispensed with and weight adaptation may be incorporated in a single equalising step. As an additional or alternative option, a hybrid equaliser architecture may be provided, where the above two-step equalisation is used during an active phase where a channel is allocated, while another weight updating scheme is used during an inactive phase where no channel is assigned. Thereby, detrimental effects of interference power can be reduced at low increase in complexity.

An electrode composition for a lithium-ion battery comprising particles having an average particle size ranging from 1 mum to 50 mum.

Individual audio tracks (20-24) for interactive reproduction at a remote toy (104) are each encoded with a sub-audible tone (12-18) or code that uniquely identifies the track with audible output and / or functional operation of the toy (104). Detection of the sub-audible tone at the interactive toy opens the audio path and permits related motor control in the toy, whereas absence of a relevant sub-audible tone disables at least the audio and, preferably, both the toy's speaker (122) and at least one controllable motor (130, 132). The sub-audible tone (12-18) or code is inserted for the duration of activity only and may come into and out of existence as a specific character track (amongst the plurality of individual audio tracks) moves between active and inactive phases. The audio tracks for remote transmission at the toys (104) are assigned to only a first channel of a stereo audio circuit, with a second channel of the stereo circuit assigned to support a context or background track that is produced from speakers (51) of a media player (54) physically separate from the remote toys (104). Conventional synchronized transmission of both stereo channels provides a basis for interaction, with synchronicity between the media player (54) and the remote toy (104) maintained by the sub-audible tones (12-18). For simultaneous audio activity in multiple toys, a different sub-audible tone is used relative to individual tones or codes used to control audio output and operation of those multiple toys.

A parametric background noise estimate is continuously updated during an active or non-silence phase so that the noise generation may immediately be started with upon the entrance of an inactive phase following the active phase. In accordance with another aspect, a spectral domain is very efficiently used in order to parameterize the background noise thereby yielding a background noise synthesis which is more realistic and thus leads to a more transparent active to inactive phase switching.
