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.

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.

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.

Disclosed herein is a torque control method for a high-speed Switched Reluctance Motor (SRM), which controls a torque in the high-speed operation of a 2-phase SRM. In the torque control method for a high-speed SRM, a positive torque (T*mA) of an active phase (A phase) of the two phases of the SRM is compensated for based on a negative torque attributable to an inactive phase (B phase) of two phases during a compensation control enable interval (ENA) ranging from a time point at which the active phase (A phase) is turned on to a time point at which tail current of the inactive phase (B phase) remains. Accordingly, the present invention can remarkably reduce a torque ripple occurring in high-speed operation mode in consideration of the influence of a negative torque attributable to tail current.

The parametric background noise estimate is continuously updated during the active phase or the non-silent phase, so that noise generation starts immediately when the inactive phase is entered after the active phase. According to another aspect, the spectral domain is used very efficiently to parameterize this background noise, thereby obtaining a more realistic background noise synthesis, and thus resulting in a more transparent active phase to inactive phase switching.

The invention relates to a method and a device for transferring printed matter onto a substrate by means of a laser beam. In particular, it relates to a method and a device for transferring a printing substance provided on a carrier to a substrate by means of a laser beam of a laser beam source. For this purpose, the output power (AL) of the laser beam source is modulated over time in such a way that the printing substance is transferred only in the active phase (AP) and not in the inactive phase (PP). At the beginning of the activation phase (AP), the brief dark phase (DP) has the consequence that the total output power AL of the laser beam during the first period is too high and thus that at the beginning of the activation phase (AP) The printed matter has been transferred. During a second period of the activation phase (AP) immediately following the first period, the total output power (AL) remains substantially constant. According to the invention, overshooting of the total output power is regulated via the duration of the dark phase (DP).

The spectral domain is 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.
