摘要： Multiple position switches and specifically in-line multiple position switches where a user has definitive points of on and off switching which are used to turn multiple redundant internal circuit switches on and off. This can provide for increased reliability of switch operation. The multi-position switch is typically a five-position switch with all five positions in-line and with double or triple redundancy at each position. The switches can also provide for the feel of a snap action mechanism between positions.

摘要： A rocker switch that can include multiple redundancy at each position. Specifically, the rocker switch is a two-position rocker switch with both positions in line and with double or triple redundancy at each position. The rocker switch still provides a user with definitive snap “on” switching and the snap positions which can be used to activate multiple redundant internal circuit switches to provide for increased reliability of switch operation.

摘要： A breathing apparatus provides gas within a hood surrounding a user's head from two oxygen tanks which each utilize a regulator. The first tank serves to inflate the hood while the second provides oxygen to the hood at a sufficient amount for human breathing for a longer time than traditionally available for such hoods. The longer life is provided through the use of micro regulators which utilize micro springs or wave washers and micro machining techniques to regulate the flow of oxygen in a way that has not been previously possible.

摘要： The control system for attachment to a collective lever in a rotorcraft which comprises a body with an extended horn portion which is generally contoured to provide for a place to rest the palm and grip the collective lever at the end in the form of an open spherical grip as opposed to the more traditional cylindrical grip used to grasp the throttle and/or collective lever directly. The control system generally includes a plurality of controls which can be manipulated by any or all of the four fingers of the hand and the thumb without need to substantially move the palm. The collective lever can also be moved without having to remove the hand from the control system or the fingers or thumb from the controls.

摘要： A pressure gauge system for a tank with a variable flow rate that provides a user with an indication of how much usable time is left in a pressurized gas tank given a particular selected flow rate or operational condition and what pressure of gas is left in the tank.
