Abstract: Disclosed is an automatic transmission system in which an ECU calculates change of the running speed to automatically shift the gears under optimal conditions. The automatic transmission system used for heavy construction equipment for variably changing a rotative speed of an output shaft by selectively engaging any one of a plurality of change gears according to the selection of oil passages of a solenoid valve includes a speed sensor for sensing the rotative speed of the output shaft or a running speed of the heavy construction equipment, a converter connected to the speed sensor, for converting a value sensed by the speed sensor into an electrical signal and a controller for receiving the electrical signal output from the converter and comparing the electrical signal with a pre-stored value, to apply a driving signal to the solenoid valve if the electrical signal is within a predetermined range, so as to shift gears.

Abstract: A light emitting diode display can be added to conventional protective helmets or incorporated in newly-manufactured helmets. LEDs increase wearer visibility during evening hours and provide decoration which appeals to the wearer and encourages use of the helmet. The LEDs are coupled to an internal power source, such as a battery in the helmet, or an external power source, such as a bicycle mounted generator, via an electric cord. The LEDs can be lit simultaneously or sequentially, the sequence being regulated by a computer chip. The timing and rate of sequence can be varied, thus making the helmet consistently interesting to the wearer and children in particular.

Abstract: The present invention concerns a lamp which can be assembled easily by the end user and is generally made up of a socket element, a housing element, and an internal element. The housing element is capable of assuming two positions: a shipping position, in which the housing is flat, and an assembled position, in which the housing element is not flat and is capable of supporting the lamp fixture. The socket element is supported by the internal element which in turns helps maintain the housing element in its assembled position. Preferably, the housing element is composed of a front layer and a back layer which are coupled on at least two peripheral edges. In the assembled position these layers are separated forming an internal space in which the internal element and the socket element are located.
