Abstract: An apparatus for adjusting a digital setting value at a variable speed includes an up key and a down key for generating a plurality of up and down pulses, an input/output interface connected to the up key and the down key, a processor connected to the input/output interface, and a display. The processor, in which a default digital setting value is stored, receives the up pulses and the down pulses through the input/output interface. The processor adds an adjustment value to or subtracts the adjustment value from the default digital setting value according to a time interval between adjacent two of the up pulses or adjacent two of the down pulses so as to obtain a digital output value to be outputted to the display, which displays the digital output value. The adjustment value increases as the time interval decreases.

Abstract: The illustrative embodiment of the present invention is a launch system that includes a closure that, in use, is attached to one or both ends of a missile canister. The closure is blown off of the canister before there is any contact between it and the nose of the missile. The closure incorporates an actuation mechanism that releases the closure when there is a rapid increase in pressure within the canister, such as when the booster of a canistered missile fires. The actuation mechanism is not, however, responsive to the magnitude of the pressure within the canister. As a consequence, the closure will not release if there is a slow build-up of pressure within the missile canister.

Abstract: A magnet type rodless cylinder comprised of cylinder tube of a double tube structure provided with an outside tube of an elliptical flattened outside circumferential shape and two inside tubes inserted into the outside tube. When pressurized air is supplied alternately to the inside tubes from a port provided at an end cap, two pistons move reciprocatingly inside the inside tubes. Due to this reciprocating motion, this reciprocating motion causes reciprocating motion of a slide magnetically coupled with the two pistons at the outside of the outside tube. The inside pressure caused by the pressurized air acts exclusively on the inside tubes and does not directly act on the outside tube of the flattened outside circumferential shape, so the thickness of the outside tube can be reduced and, even if the cylinder tube is made a double tube structure, the total thickness will not become greater than in the past.

Abstract: The present invention is directed to a system and a method for accurately locating a penetrating-type weapon within a shelter for detonation at a desired target site. The method includes detecting a deceleration threshold event indicative of the penetrating weapon impacting and traversing a layer of shelter having certain material or structural characteristics (e.g., a “hard” or a “thick” layer). A delayed detonation program or process is enabled upon detection of the threshold event. For example, a delayed detonation program or process may include layer counting, void counting, or a combination of layer and void counting until the desired number of layers (and/or voids) of a shelter has been detected, at which time the weapon may be detonated. Any deceleration events that occur prior to the deceleration threshold event are ignored to minimize the potential failure of detecting specific types of layers including certain types of “soft” or “thin” layers.
