20090273763 | COLOR WHEEL - A light fixture having at least one light source for generating a beam of light, a plurality of color filters are rotatable into position to intercept the light beam. The color filters are fixed to the color wheel by a central spring which has a number of radial protruding tongues for fixation of the color filters. The color filters are removable yet are secured in a correct position by radial protrusions formed between the color filters an circular outer protrusion located outward of the color filters so as to form a cavity that surrounds the color filter at both sides as well as at outward. Inward of the color filters, they are fixed by the protruding tongue that presses them down and keeps them in place. This leads to a nearly perfect fixation of each color filter, which can be exchanged if necessary. | 11-05-2009 |

20090231111 | METHOD AND APPARATUS FOR ENTERTAINMENT COMPRISING RFID TAGS - The present invention relates to a method and an apparatus primarily for entertainment, which method or apparatus comprises an electronic control system, comprising at least one processor, which processor controls and stores at least some operational parameters during operation of the apparatus. The scope of the invention is to achieve access to data stored in an entertainment system or apparatus in periods of non-operation. This can be achieved if the apparatus comprises a RFID tag, which RFID tag can be communicating with the processor during operation, which RFID tag comprises at least one memory, which memory can contain copy of data segment representing at least one operational parameter for the apparatus, which RFID tag can be accessible from outside the apparatus in an operational or non-operational period, where an external device can read or write in the data segment in the memory in the RFID tag. It is hereby achieved that data could be transmitted in and out of the RFID tag during operation of an apparatus. Data transmitted out from the RFID tag could be information about addresses for normal communication with the apparatus using the DMX protocol as an example. These addresses could then be exchanged from the outside if the address for a specific apparatus has to be changed. After operation of an entertainment apparatus, for example when it is ready for transportation for a performance, an RFID scanner could be used to control failures or critical parameters in the apparatus so that apparatuses that show any critical parameters are sent for repair while operators showing normal activity will be transported for the next show. | 09-17-2009 |
20090230892 | SAFETY LOOP FOR A LIGHT FIXTURE - A light fixture and a method for control of a light fixture is supervised by at least one thermoswitch which protects the light source by disconnecting the power supply to the light source at elevated temperature. To achieve a safety circuit in a light fixture without switching the supply circuit to a light source, the at least one thermoswitch is connected to a low voltage safety loop, which safety loop is connected to a current source that generates a constant current in the safety loop. The safety loop is supervised by a current measuring device. Hereby, it is achieved that the switching, if temperature rises, is achieved by switching contacts that only carry a very limited current. This will increase the life time of the thermoswitch and very small switches can be used. | 09-17-2009 |
20090212947 | INTRUDER DETERRENT SYSTEM - A system and a method for operating an intruder deterrent system by which a smoke screen is generated in response to an intruder being detected, a smoke screen generator operatively linked to the intruder detecting. To achieve an intruder deterrent system that can operate for a longer period after interruption in the power supply, latent heat is stored in a heat storage, and smoke can be generated by transferring the latent heat from the heat storage to a liquid, which liquid is evaporated. The use of the heat storage has led to the unexpected result that the smoke generator can operate independently of power to the heating elements for a very long period. | 08-27-2009 |

Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path. In other words, no angling, bending or twisting is necessary, so a minimum of space is required. | 05-14-2009 |
