A device to process and transport medical instruments in a protected manner comprises a containing body (14), in which to place a medical instrument (12), and a closing body (16), in which the containing body (14) and the closing body (16) are configured mobile with respect to each other, in order to define a hermetically closed condition and an open condition. The device comprises at least one sensor (30) configured to automatically detect a variation between the open condition and the hermetically closed condition and to transmit a corresponding signal, and an electronic state display (26) configured to receive the signal from the sensor (30) and to display toward the outside information regarding the current state associated specifically to the signal received.

A system for distinguishing target metal objects from each other in close proximity to each other. The method includes transmitting a first sinusoid signal via a first transmit coil to a first receive coil in close proximity to the first transmit coil; transmitting a second sinusoidal signal at a second frequency and amplitude different from the first frequency and amplitude to a second receive coil arranged in close proximity to the second transmit coil and in close proximity to the first receive coil such that received signals in the first and second receive coils include first and second frequency signals from the other of the first and second transmit coils. The received signals are separated via frequency domain multiplexing. The signals are compared to detect a presence of the target having a signal magnitude different from the first received signal and the received second signal and a known reference point.

A spray gun includes a gun body, a flow passage, a fluid driving element, a control module, a switch assembly and a battery pack. The control module is configured to obtain power information of the battery pack and/or working state information of the fluid driving element, and display the power information of the battery pack and/or the working state information of the fluid driving element through a visual interface module.

This system was designed to resolve dirt and dust accumulation in confined areas on mobile and stationary equipment, and other types of plant equipment, including equipment of offshore oil and gas platforms, maritime vessels, and others, and more generally any kind of motorized or mechanical equipment with internal areas that accumulate dust and dirt. The areas where dust and dirt accumulation occur would normally only be accessible by removing major components. The system may be designed to utilize existing pressure washers and air systems. The supply manifold may be constructed from steel, hydraulic lines, pressure wash nozzles and angled fittings. The installer may assess areas of accumulation, directing the nozzles at the general area. Once the system has been installed, mechanical operators may easily attach the device to a pressure source. Quick connect fittings would be installed outside the machine, connecting pressurized water or air to the supply manifold.
