The present invention relates to a display device comprising at least one display unit and an illumination device for illuminating an edge region of the at least one display unit. The invention further relates to a method for operating such a display device and to an entertainment device comprising such a display device. The display device according to the invention comprises, in addition to the at least one display unit and the illumination device, at least one determination means for determining a color information from an image block of the at least one display unit, and further comprises a color control means for controlling the color and/or color spectrum of the light emitted by the illumination device as a function of the color information. The color information can be obtained from the light which is actually emitted by the display unit in said image block, for which a light detection device having an observation region that is limited to the image block can be provided.

Display device and method for operating such a display device

The present disclosure relates to a display device comprising at least two display units as well as an illuminating device for illuminating a transition area between the at least two display units. The disclosure further relates to a method of operating such a display device as well as an entertainment machine comprising such a display device.

Display device and method for illuminating an edge area thereof

Arrangement and method for identifying fingerprints, including at least one fingerprint sensor and at least two electrodes, wherein a fingerprint can be detected by the sensor. A first electrode is arranged in the vicinity of a hand support surface at a distance from the support surface such that when a finger is placed on the support surface, the thumb can be placed on the first electrode. At least one second electrode is arranged on the support surface such that at least one finger can be placed on the second electrode. The sensor and the first electrode and/or the at least one second electrode are each designed as one unit. Electric signals are transmitted to the hand via the electrodes by a measuring unit for applying and analyzing the electric signals, and the changes of the electric signals are detected. An identification result is ascertained using the detected fingerprints and signals.

Arrangement and method for identifying fingerprints

Devices with a fingerprint sensor paired with a handle or a hand support. The fingerprint sensor is arranged in the vicinity of the handle or the hand support surface at a distance from the handle or hand support surface such that when an index, and/or middle, and/or ring, and/or little finger of a hand grips the handle or an index, and/or middle, and/or ring, and/or little finger of a hand is placed on the support surface, the thumb the hand can be placed on the fingerprint sensor such that a longitudinal axis of the thumb substantially coincides with a main axis of the fingerprint sensor. The thumb is placed either next to the handle and thus on the fingerprint sensor or the fingerprint sensor is arranged on a housing side of the device.

Device with fingerprint sensor

A method and system for using a touch interface to detect a lateral edge of a human hand of a user to selectively reveal an item to the user. The method includes providing a general purpose computer having a main board with program memory, software, a processor and RAM connected in operative communication, providing an interface in operative communication with the processor, the interface being accessible by the user. The interface includes a touch screen that detects multiple points of contact indicative of the lateral edge of the human hand and reveals the item to the user in response to the step of detecting. The interface detects movement of the multiple points of contact and reveals the item at a position on the touch screen determined by the position of the multiple points of contact. Detecting movement further causes the item to track the movement.

The present invention relates to an air cleaner for removing air pollutants from an air stream, for instance such as the cleaning exhaust/intake gas of an amusement machine, said air cleaner comprising a filter device including at least one filter layer () held by a filter holder () in said airflow substantially perpendicular to a main flow direction thereof and including a plurality of preferably stick-shaped filter elements () neighbouring each other. In accordance with the present invention, the filter device has no closed surrounding along the circumference of the filter layers, but provides for an open side along at least a portion of the periphery of the filter layer. At least one circumferential side section () of the filter layer parallel to or tangential to the longitudinal axis of an outermost filter element is formed as an open side free of flow control elements surrounding the filter layer. Contrary to the prior art where the filter layer is usually enclosed in a tubular flow channel, the present invention avoids such flow-control-elements for guiding the air stream through the filter layer and/or preventing the airflow from diverging away from the filter layer, wherein in particular the filter layer, at its open side, is dispensed with flow-control-elements such as flow guiding surfaces, flow channel walls, fences or housing walls surrounding the filter layer.

Air cleaner for removing air pollutants from an air stream

An apparatus and method including a multi-touch interface for card gaming includes providing a multi-touch interface for displaying a card having a hidden value. The method includes detecting a touch on the interface. The touch has a curved pattern with multiple points of contact with the interface. The curved pattern is indicative of the lateral edge of a human hand in contact with the interface, oriented to hide the card from others. The method then detects movement of the multiple points of contact sweeping over a portion of the interface to reveal the value of the card to the user.
