Abstract: A lawn maintenance device may include a cutting deck, rotating shaft with a blade holder attached to the rotating shaft. The blade holder may include grooves for attachment of the blade to the holder.

Abstract: A multiple rear drive axle system for a vehicle includes a first axle coupled with a drive shaft from a transmission of the vehicle. The first axle includes a first cantilevered input pinion mechanically coupled with the drive shaft and with a first driven gear. The system also includes an output shaft mechanically coupled with the drive shaft. A second axle has a second cantilevered input pinion mechanically coupled with the output shaft of the first axle system and with a second driven gear. The first and second input pinions are common, that is, are substantially identical pinions. The first and second driven gears are also common, that is, are substantially identical gears.

Abstract: There is provided a universal serial interconnection strategy which allows individual internal gaming machine components, sub-assemblies and sub-systems to be connected to a controller. Each component bears a globally unique identification number (GUIN) which allows the controller to recognize, enumerate and authenticate the device and to reconfigure itself or another programmable component of the gaming machine for proper communication with the device having the particular GUIN. In addition to internal gaming machine components, external components such as secondary or tertiary games may also be connected to a controller within a gaming machine to which the games are attached. The universal serial interconnection strategy of the invention thereby provides a “Plug-and-Play” (PNP) style interface which can eliminate the point-to-point interconnection of gaming machine components used in gaming machine of the prior art.

Abstract: A system and method for producing a high repetition pulsed microjet for use in medical applications. The device includes a stagnation chamber and a hydraulic pump for pumping a sterile fluid into the stagnation chamber. A flexible walled volume disposed in the stagnation chamber and filled with a hydraulic fluid. The hydraulic piston is cyclically displaced towards/away from the stagnation chamber thereby increasing/decreasing the pressure of the hydraulic fluid on the flexible walled volume. In turn, the flexible walled volume is compressed and the sterile fluid is expelled through an orifice in the flexible walled volume under pressure producing the pulsed microjet. This process may be repeated to produce repetitive pulsed microjets. In addition, the flow conduction of the hydraulic fluid between the hydraulic pump and stagnation chamber may be controlled by inserting a blocking device therebetween.

Abstract: The invention relates to an ignition system for an internal combustion engine (ICE) that provides fast transfer from a laminar combustion in an ignition kernel to a self-sustaining turbulent flame propagation, thus leading to a reduction in the total time of combustion. The effect is achieved by transiently attacking the ignition kernel with a high-frequency (HF) electromagnetic radiation pulse, which is quasiperiodically modulated with 10-1000 kHz frequency in the initial period of combustion (50-500 .mu.s) following the ignition. Radiation is absorbed by electrons existing only inside the ignition kernel during the initial stage of its development. Due to thermal inertia, the medium perceives the oscillations on the frequency of modulation, whereby the surface of the kernel is developed and is split into separate fractions. This causes transfer from laminar to turbulent bulk combustion.
