A system for ensuring proper fit of a negative-pressure respirator is disclosed. The system includes a negative-pressure respirator that a user can wear, and a sensor positioned within the interior of the respirator. The sensor contains a sensing element capable of detecting fluid-soluble particulate matter and generating data based on shifts in an electrical property of the sensing element. This data is forwarded to a mobile computing device configured with one or more processors and associated memory. The mobile device, upon executing instructions stored in its memory, receives the particulate matter data from the sensor and analyzes whether the respirator meets a preset fit-test criterion. Based on that determination, the device presents at least one graphical element on its display, instructing the user to perform a specific action that facilitates or confirms proper fit of the respirator.

A sweating simulator has a foundation panel (14), a panel (1) and a temperature control panel (2), a fixture for fixing a specimen, a container (7) for holding simulated sweat, a container (15) for collecting the simulated sweat, and a plurality of weighing scales for measuring masses of the simulated sweat supplied, evaporated and dripped from the specimen, respectively. The panel (1) and temperature control panel (2) constitute a simulated sweating plane for simulating wetting properties and temperature of skin. An upper middle position of the temperature control panel (2) has a sweating zone (3), which has a plurality of sweating pores (4). The temperature control panel (2) has a temperature sensor (8) and a heating element to control the temperature of the temperature control panel (2) around 33-35 C. to simulate the temperature of the human skin surface. The sweating rate of the sweating zone (3) is in the range of about 1 to 624 ml/h or about 0.004 to 2.5 L/h-m.sup.2 to simulate various sweating intensities.

An inflatable hip model includes an inflatable body with a hip shape. The inflatable body is internally provided with a pull strap, the pull strap at least including two first ends and a second end. The pull strap is connected to the inflatable body through the two first ends respectively to form a first connecting portion. The pull strap is connected to the inflatable body through the second end to form a second connecting portion. The pull strap is used for acting on the inflatable body, so that the inflatable body in an inflated state forms concave regions at the first connecting portion and the second connecting portion. A center front sheet is formed in the region between the two connecting portions of the inflatable body, and a hip seam portion is formed at the second connecting portion.

According to some embodiments, a system comprises a generator of a truly random signal is connected to an input and feedback device for the purpose of providing a user with real time feedback on the random signal. The user observes a representation of the signal in the process of an external physical event for the purpose of finding a correlation between the random output and what happens during the physical event. In some examples, the system is preferably designed such the system is shielded from all classically known forces such as gravity, physical pressure, motion, electromagnetic fields, humidity, etc. and/or, such classical forces are factored out of the process as much as possible. The system is thus designed to be selectively response to signals from living creatures, in particular, humans.
