In addition to the foregoing, many miter saw arrangements include a laser alignment device. However, it is often difficult for the designer of the saw to find a location on the saw to mount an alignment system where the laser beam is directed to a desired location without physical obstruction during operation of the saw. Furthermore, certain mounting locations on the saw will cause the laser beam to shift out of an intended cutting line when the blade of the saw is not in a cutting position. Therefore, it would be desirable to provide a miter saw with a laser alignment guide that is mounted in a position that will not result in obstruction of the laser beam or movement of the laser beam out of the cut line. It would also be advantageous if such laser alignment arrangement could be easily adjusted to properly align the laser along the desired cut line. It would also be advantageous if the laser alignment arrangement could be easily and conveniently mounted and adjusted using an inexpensive mounting and adjustment system.
In view of the foregoing, it would be desirable to provide a miter saw with an improved bevel lock. It would also be desirable to provide a miter saw with an improved positive stop arrangement. Additionally, it would also be desirable to provide a miter saw with an improved extension support arrangement. Furthermore, it would be desirable to provide a miter saw with an improved laser alignment system. While it would be desirable to provide a miter saw that provides one or more of these or other features, the teachings disclosed herein extend to those embodiments which fall within the scope of the appended claims, regardless of whether they accomplish one or more of the above-mentioned advantages or include one or more of the above-mentioned features. The invention relates to a self-powered remote control device comprising:                transmission means,        a feeder circuit connected to the transmission means,        a generator supplying electric power connected to the feeder circuit, and        control means associated to the electric power generator.        
Known remote control devices generally comprise a transmitter and a receiver to control an electrical apparatus. Transmitters of known type have electronic circuits enabling a high frequency, infrared or ultrasonic electromagnetic radiation to be emitted. The radiation emitted by the transmitters is preferably modulated and encoded to provide satisfactory operating safety when several transmitters and receivers are used.
The receivers receive the emitted radiation, then detect and decode the signal received. The decoded signal is used by electronic circuits to control in particular electrical apparatuses.
Fixed or mobile self-powered transmitters generally require a power supply provided by
an extended position that is relatively wide. 
 In addition to the foregoing, many miter joint see arrangements include a laser alliance device. However, it is much difficult for the designer of the power saw to find oneself a location on the saw to mount an alignment organization where the laser beam is directed to a hope placement without physical obstruction during operation of the saw. Furthermore, certain mount locations on the saw will cause the laser balance beam to shift out of an intended cutting line when the sword of the saw is not in a carving position. Therefore, it would be desirable to provide a miter joint saw with a laser alignment guide that is mounted in a position that will not result in obstacle of the laser radio beam or movement of the laser beam out of the cut line. It would also be advantageous if such laser alignment arrangement could be easily adjusted to by rights align the laser along the desire cut occupation. It would besides be advantageous if the laser conjunction arrangement could be easily and handily mounted and adjust using an inexpensive mount and adjustment system. 
 In view of the foregoing, it would be desirable to provide a miter saw with an improved bevel lock. It would also be desirable to provide a miter saw with an improved plus catch arrangement. Additionally, it would also be desirable to provide a miter saw with an improved elongation support arrangement. Furthermore, it would be desirable to provide a miter joint saw with an improved laser conjunction system. While it would be desirable to provide a miter joint saw that provides one or more of these or other features, the teachings unwrap herein extend to those embodiment which fall within the setting of the appended claims, regardless of whether they achieve one or more of the above - mentioned advantages or include one or more of the above - mentioned features. The invention associate to a self - powered outside control device comprising:                 transmission means,         a feeder tour connected to the transmission mean,         a generator supplying electric power connected to the feeder circuit, and         control means consociate to the electric power generator.        
 Known remote control devices generally comprise a sender and a liquidator to control an electrical apparatus. Transmitters of known type have electronic circuit enabling a high frequency, infrared or ultrasonic electromagnetic radiotherapy to be emitted. The radiation emitted by the transmitters is preferably modulated and encode to provide satisfactory operating safety when several transmitters and receivers are used. 
 The receivers pick up the emitted radiation, then detect and decode the signal received. The decoded signal is used by electronic circuits to control in particular electric apparatus.
