Abstract: The invention provides a drinking vessel into which dry ice can be placed in order to produce fog above the beverage. In order to prevent the pieces of dry ice from being swallowed, a second bottom is inserted into the drinking vessel after the dry ice was placed therein. The second bottom features holes that are permeable to the beverage, but not permeable to the pieces of dry ice. Consequently, the beverage comes in contact with the dry ice such that fog is created while the dry ice is simultaneously prevented from rising to the surface.

Abstract: A mechanism for assigning an actuator to a device. It includes a transmitter on the device side for transmitting a scanning signal as well as a processing unit on the actuator side which include means for receiving scanning signals and which emits a contact signal when a scanning signal matches a previously defined reference signal. The processing system emits the contact signal only at the end of a predetermined time delay, which is characteristic for a specific actuator, after receiving the scanning signal.

Abstract: A method is for controlling entry, e.g., into a motor vehicle, during which a key and a base station wirelessly exchange authentication data between one another in an active or a passive communication mode. At the beginning of the authentication process, the base station transmits a call signal to the key, and the key replies to the call signal with a reply signal. The base station verifies the received reply signal of the key in the communications mode in which the reply signal was received. If the reply signal of the key was received in the active communications mode, the base station transmits a first selection instruction to the key thus causing the key to perform the subsequent communication in the active communications mode. If the reply signal of the key was received in the passive communications mode, the base station transmits a second selection instruction to the key thus causing the electronic key to perform the subsequent communication in the passive communications mode.

In one embodiment of motor vehicle door lock system, the activation of the outside handle by the hand of an operator or the approach to the outside door handle is recognized early. A vibration generator is assigned to the outside door handle such that the outside door handle or a part thereof is mechanically vibrated. A sensor is provided for acquiring the vibration, the sound waves caused by the vibration and/or their reflections so that the motor vehicle door lock system can detect when the outside door handle or a part thereof is being approached and/or touched and/or activated by the hand of an operator.

Abstract: An authorization checking system for motor vehicles, in which a control unit in the motor vehicle, having a portable user-transponder, in an inquiry-response dialog using data exchange, checks, and allows or blocks, the authorization for unlocking or locking the vehicle doors as well as for starting or driving. In order to be able to modify the identifiers of user-transponders and components of the motor vehicle in a security-relevant manner, a so-called master-transponder is provided in addition to one or a plurality of user-transponders. The master-transponder has a particular, vehicle-specific identifier, using which, in a special-inquiry-response dialog, the authorization to carry out and complete special functions within a preselected scope, going beyond the access and start/drive authorization, can be checked, and allowed or blocked. For carrying out the special functions, the master-transponder has acoustical and/or optical display devices and/or input devices.

Abstract: A motor vehicle door lock system, an outside door handle arrangement, and a process for controlling a motor vehicle door lock system are proposed. For simple, economical sensing of the actuation of an outside door handle, a first signal is detected when the outside door handle is touched, and when the outside door handle is released a second signal is detected, the signals being evaluated as the start and end of actuation of the outside door handle. Alternatively or in addition, it is provided that a pressure load on the outside door handle is detected for locking the assigned motor vehicle door lock.

Abstract: A device for locking and unlocking a door of an object, particularly of a motor vehicle, includes a transmitter unit disposed on the object and a transponder assigned to a user. Safety is increased because, in response to alignment of the transmission lobe with the interior of the object, the range of the field of the transmission lobe formed by the transmitter unit or of the signals emmitted by the transponder can be reduced or disturbed by a switching device, so that a transponder located in the passenger area of the interior cannot be queried.

Abstract: A device is proposed for ascertaining distance and transmitting data in a motor vehicle. It has a transmitting arrangement for generating and emitting a radar signal. A receiving arrangement receives a radar signal. It is characterized in that switchover arrangements are provided which cause the transmitting and/or receiving arrangement to operate either in a radar operating mode for detecting the distance and/or speed of a further object, or in a data-exchange operating mode for the exchange of data with a transceiver. Specific functions are enabled in dependence on the data exchange.

Abstract: A motor vehicle door lock system whereby at least one of spatial proximity of an operator to the outside door handle and a physical touching of the outside door handle by the operator can be easily detected using a comparatively low power source exhibiting excellent response behavior. One aspect includes a passive entry function of the motor vehicle door lock system can be activated or a starting interval of the control electronics can be initiated. The lock system utilizes ultrasonic waves for the detection of the at least one of spatial proximity of an operator to the outside door handle and a physical touching of the outside door handle by the operator. To sense spatial proximity to the outside door handle and/or touching of the outside door handle at least essentially solely in the access space defined by the outside door handle, an ultrasonic field is produced whereby changes and/or interruptions of the ultrasonic field is detected upon the occurrence of these events.

Abstract: A method and a device for allocating an authentication device to a base station, with the base station delivering a search signal which is received by the authentication device and is compared with a previously stored reference signal assigned to a base station. If the search signal matches a reference signal, the authentication device sends a response signal. If they do not match, the authentication device checks whether the search signal matches another previously stored reference signal allocated to another base station.

Abstract: A steering wheel (10) is proposed, especially for controlling a motor vehicle, which is provided with a device that detects the elastic deformation of the sheath of the steering wheel (10) caused by its being gripped by the driver, and which controls vehicle-specific functions on the basis of this deformation. To that end, a fiber-optical sensor is mounted on the steering wheel (10). This sensor has an optical fiber (14), into which a transmitter (16) injects a light signal (16.1), which is received by a pickup (18). Exertions of pressure or force on the optical fiber (14) cause a change in polarization of the light signal (16.1), which is evaluated by an evaluation circuit (15) to form a driver signal (20.x).
