  • Patent number: 8872052
    Abstract: This novel jumper features an integrated mechanical switch that allows resetting the CMOS memory of computer motherboards just by actuating a reset button on the jumper, instead of moving a prior-art jumper back and forth over the CMOS-reset block. The disclosed jumper can also be adapted for use as temporary button for powering on, restarting and resetting motherboards when tested alone; in this case the jumper just needs to be inserted over the corresponding pair of pins on the front-panel header of the motherboard. This jumper is also applicable to other electric or electronic devices where operating the jumper's integrated switch is more convenient or safer than moving prior-art jumpers or manually shorting up pins on printed circuit boards.

  • Patent number: 7599778
    Abstract: This is a constant-mesh transmission that uses special latches, electromagnetic actuators to operate said latches, and an associated computerized control unit to command said actuators and, at the same time, synchronize the speed of the motor/engine and the gear trains with the speed of the transmission output shaft. During gear ratio changes, the transmission control cooperates with the motor/engine control in such a way that speed differences between—and torque transmitted through—the gear trains involved and the output shaft are minimal; this permits effortless and on-the-fly coupling and decoupling of gears to/from the output shaft, without requiring any clutch operation. This transmission can be used in a variety of automotive and industrial applications, and is mainly intended for automotive vehicles with internal combustion engines.

  • Patent number: 7305963
    Abstract: This is simple and efficient rotary machine that can be implemented as compressor, pump, motor and mainly as internal combustion engine. The engine comprises a housing, a rotor(s) with a radial blade(s), a chamber(s) swept by the blade(s), an intersecting planar valve(s) with slot, and a combustion chamber. Blades and slots have matching shapes that allow the traversal of the blades through the slots with negligible loss of air/gases. After traversing the slot, the blade aspires air into one side of the chamber while compresses air on the other side. Fuel is injected in the compressed stream in its way to the combustion chamber, where it is ignited. In a double-rotor implementation, combustion gases are then introduced in the second rotor chamber, just after its blade has traversed the corresponding slot. One side of this blade is pushed by the expansion while the other expels gases from the previous stroke.
