Abstract: In an erroneous opening prevention mechanism according to the present invention, a hook and a hook support are loosely engaged with one another when a front lid, folded back on a back lid, is unfolded, or laid flat. If an attempt to raise the whole lid laid flat on a grand piano main body is made, it is impossible to raise the lid due to the locking of the hook and the hook support. When the front lid is folded back onto the back lid, on the contrary, the hook and the hook support are released from one another and, therefore, the whole lid can be raised. Accordingly, the erroneous opening prevention mechanism prevents the whole lid from being raised without first folding back the front lid.

Abstract: RF beam sources, also referred to as HPM sources, serve in the non-lethal destruction, interference or screening of targets. In an autonomous RF beam source (2) operated with an explosive material (10), a fuze (11) of a magnetic flux compressor (4) is ignited by a battery (3), with time or impact control. Consequently, the highly-explosive material (10) located in the liner ruptures the coil body in a conventional manner, and the individual windings (6.2) are short-circuited consecutively. The generated voltage is then amplified and transmitted via a high-pressure spark gap to a UWB chopper for generating pulses, which are subsequently radiated via a broadband antenna that is adapted with the cable resistance of the UWB pulse. In contrast, the invention provides constructing an explosive-triggered RF beam source (2) solely from a pulse generator or a pulse-generation device (4), whose generated pulses are radiated directly at a target.

Abstract: A gas conducting system, particularly a compressed air system for a motor vehicle, which includes a filter containing a desiccant for removing moisture from a gas passed therethrough. The housing structure of the filter is provided with a seal with a weakened area 18, which specifically causes any overpressure to be reduced through failure of the weakened area if the pressure inside exceeds a permissible maximum. This process can be repeated multiple times until the seal with the weakened area 18 must be replaced due to aging. The weakened area can be used as a substitute for a pressure relief valve or as supplemental protection in case the pressure control valve fails, e.g., due to ice. This can prevent, for instance, bursting of the filter housing which could present a safety risk.

Abstract: A system and method for passive hypoxic training provides a person with a low oxygen (hypoxic) environment. Oxygen sensors automatically monitor and control oxygen levels to maintain the altitude desired. CO2 levels are monitored and CO2 is eliminated so that the air a person breathes is substantially clean and fresh. Exposure to a high altitude environment produces physiological changes in a person's body, which becomes more efficient at absorbing and transporting oxygen. Using the present method and system, athletes obtain the benefits of sleeping at a simulated altitude in the user's own home for six to twelve hours, rather than traditional altitude therapies in which athletes spend two to three weeks at high altitude before an athletic competition to obtain similar benefits. This system allows for “live high train low” altitude training that has been shown in controlled studies to provide superior benefits to “live high train high” training.
