Abstract: A position determination method including a step of transmitting a periodic signal having a carrier frequency, a step of sequentially receiving the periodic signal having the carrier frequency at various locations using at least one antenna, and a step of determining a first coordinate of the object location on the basis of a zero crossing of a Doppler frequency response which may be associated with the first coordinate of the object location, the first coordinate of the object location corresponding to a coordinate of that location of the at least one antenna which it has when receiving the periodic signal at the zero crossing in relation to the object location.

Abstract: An apparatus such as a television signal processing apparatus provides a means to control power dissipation by high speed signal processing circuitry associated with tuners while continuing to receive auxiliary data such as administrative data, guide data, or emergency alert notifications.

Abstract: A device for generating a magnetic field in a goal area with at least two coils arranged in parallel to a goal area defined and bounded by a goal, wherein a first coil is attached in an area behind the goal and a second coil is attached closer to the goal than the first coil or identical to the goal, wherein the first coil and the second coil respectively have a coil impedance, wherein the coil impedance of the second coil is set so that a magnetic field of the second coil generated due to a magnetic field of the first coil reduces the magnetic field of the first coil at a location within the second coil by at least 20%.

Abstract: A programmable lighting unit includes a radio interface to be remote controlled by a radio remote control. In particular, the remote control sends parameter data which is supplied to parameter adjustment means in the programmable lighting unit which programs the parameter data such that a controller of the programmable lighting unit controls a controllable lamp dependent on the parameter data. In particular, the controller is adapted to be programmed using the one or the multiple parameters such that a reaction by the controller to the control data depends on the one or the multiple parameters.

Abstract: A method of detecting a contact between a player and a ball in a ball game, comprising a step of generating a magnetic field which may be associated with the player, the magnetic field being generated with a code sequence or a frequency which differ from a code sequence or a frequency which may be associated with the other player of the ball game, a step of detecting the magnetic field which may be associated with the player, and a step of determining the code sequence or the frequency with which the magnetic field was sent so as to obtain, on the basis of the code sequence or frequency, ball-contact information indicating whether the player had contact with the ball.

Abstract: A game ball wherein in the vicinity of a goal, or in a goal area, an electronic system is activated in the goal area by an activation signal, which may be a magnetic field or a radio signal, so as to subsequently facilitate, e.g., highly precise position measurement of the game device, or game ball.

Abstract: A position determination method including a step of transmitting a periodic signal having a carrier frequency, a step of sequentially receiving the periodic signal having the carrier frequency at various locations using at least one antenna, and a step of determining a first coordinate of the object location on the basis of a zero crossing of a Doppler frequency response which may be associated with the first coordinate of the object location, the first coordinate of the object location corresponding to a coordinate of that location of the at least one antenna which it has when receiving the periodic signal at the zero crossing in relation to the object location.

Abstract: A method for deciding whether a movable object has been brought through a goal having a goal area defined by the goal, an internal magnetic field being measurable, within the goal area or in parallel with the goal area, which is larger than an external magnetic field present outside the goal area, the method including a step of generating the internal magnetic field within the goal, a step of providing information about a magnetic field experienced by the movable object, and a step of evaluating the information about the magnetic field to provide a goal statement by means of a detection that the movable object has passed through the internal magnetic field.

Abstract: A device for controlling at least two coils located at different positions with regard to a positioning area, for indicating a position of an object located within the range of magnetic fields generated by the coils, the device including a generator for generating coil enable signals for the at least two coils using a multiplexing technique.

Abstract: For measuring a shot force exerted on a movable game device, a time curve of the acceleration during the shot or of the pressure within the game device during the shot is recorded and processed to obtain an energy measure, said energy measure then serving to provide information about the shot force.

Abstract: For measuring the rotational frequency of a movable game device, one resorts to an existing radio signal in the form of a broadcast signal or mobile communication signal within the framework of an open system, or to a radio signal of an evaluation unit within the framework of a closed system, so as to obtain, by means of an antenna having a directivity characteristic, a time-varying radio antenna receive signal which has a low-frequency modulation portion, the frequency of which corresponding to the rotational frequency of the movable game device.

Abstract: The movable device includes a detector for detecting that an object is located in the vicinity of or at the movable device, as well as a transmitter module for transmitting two signals having different signals speeds. These two signals are received by a receiver, the receiver having a detector to ascertain whether the second signal arrives within a predetermined time period as of reception of the first signal, so as to provide, when this has been detected, a detector signal indicating that the movable device has been contacted by the object. Exemplary movable devices are game devices such as footballs. Exemplary objects are arms, legs, football shoes, rackets, bats, etc.
