Abstract: A control method is considered for use in controlling one or more transducers of an automobile, the control method comprising: generating, for a haptic event having a haptic output, an audio/visual control signal for at least one audio/visual transducer of the one or more transducers so that at least a corresponding audio or visual output accompanying the haptic output is a function of a level of ambient vibration in an operational environment of the one or more transducers, wherein the operational environment is an automotive environment.

Abstract: An automotive haptic control system for controlling a haptic output of a haptic actuator of an automobile, the haptic control system comprising: a haptic controller configured to: obtain vibrational information indicative of a level of ambient vibration in an operational environment of the haptic actuator, wherein the operational environment is an automotive environment; determine the level of ambient vibration from the vibrational information; and generate a haptic control signal for use in controlling the haptic output of the haptic actuator, wherein a value of the haptic control signal is a function of the level of ambient vibration.

Abstract: This application describes methods and apparatus for loudspeaker protection. A loudspeaker protection system (1100) is described having a first frequency band-splitter (102) for splitting an input audio signal (Vin) into a plurality of audio signals (v1, v2 . . . ,vn) in different respective frequency bands (?1, ?2 . . . ??). A first gain block (103) is configured to apply a respective frequency band gain (gt1, gt2 . . . ,gt3) to each of the audio signals in the different respective frequency bands and a gain controller (109; 1101) is provided for controlling the respective band gains. A thermal controller (1101) determines, for each of a plurality of the different respective frequency bands, a power dissipation for the loudspeaker in that frequency band and also determines a respective thermal gain setting based on the determined power dissipation for that frequency band. The gain controller is configured to control the respective frequency band gains based on the thermal gain settings.

Abstract: A method of thermal protection of a voice coil of a loudspeaker comprises: determining an estimate of a temperature of the voice coil, determining an estimate of a rate of change of the temperature of the voice coil, determining an estimate of power dissipation in the voice coil, and generating a gain control signal for modulating a gain applied to an input signal in a signal path between an input terminal and the loudspeaker. The gain control signal is generated as a function of all of the estimate of the temperature of the voice coil, the estimate of the rate of change of the temperature of the voice coil, and the estimate of the power dissipation in the voice coil.

Abstract: A system for decentralized ordering of goods and/or services such as food and/or drinks at a venue such as a hotel or restaurant is disclosed. The venue uploads a venue menu to an internet site via the venue's data device or computer. An order application is downloaded by prospective customers from the internet site to the mobile data device of each customer. In addition, the venue allocates a customer identification code to each customer which is stored in the customer's mobile data device. Therefore the customer can use his mobile data device to access the venue's menu and order items from the menu. Preferably the customer notifies his location within the venue and the order is delivered to the customer's location.
