    Abstract: A tamper proof locking mechanism incorporating a first fixture for attachment to an index protective cover, a second fixture for attachment to an instrument, and a third fixture for connecting the first fixture to the second fixture. The first fixture may have a receptacle, the second fixture may have a plate with an opening, and the third fixture may have a protrusive structure that fits into the receptacle of the first fixture and into the opening in the plate to connect the first fixture to the second fixture. The protrusive structure may have a rivet that is partially embedded with a plastic-like material that reveals tampering when an attempt is made to break a connection between the first fixture and the second fixture.

    Abstract: In an embodiment, a system comprises a valve disc configured in an overpressure protection device. The system can also include a valve gasket configured to rest on the valve disc. The system also includes a valve seat configured above the valve gasket, wherein the valve gasket is sealed in between the valve seat and the valve disc. The system further includes a supporting structure configured above the valve seat. The supporting structure is configured to enable the valve gasket to remain in position between the valve disc and the valve seat in response to an increase in pressure.

    Abstract: A sensor apparatus and a method of operating the sensor apparatus can include one or more sensors and a circuit board, wherein the one or more sensors can include a rotatable component (e.g., pulse disk, crank, pin, shaft, etc), and an angular circuit board assembly that maintains the circuit board in an angular position with respect to the rotatable component in an arrangement that allows the rotatable component to dive through the circuit board. The sensor can be, for example, a magnetic sensor, a light emitting diode or a photo diode. The sensor apparatus can include a flow channel and the rotatable component can oscillate to provide a measurement of a flow of fluid through the flow channel. The sensor apparatus can be used for the mechanical/electrical detection of pulses of a rotary motion.

    Abstract: A phototransistor apparatus and a method of operating the phototransistor apparatus. The phototransistor apparatus can include a phototransistor, a light source, and a supply voltage associated with the phototransistor. After switching on the supply voltage, the phototransistor can generate a phototransistor signal that is scanned, wherein the supply voltage associated with the phototransistor is switched on later than the light source, and wherein charge carriers in a base area of the phototransistor are reactive to a light pulse from the light source in a currentless state, and continue to react after the light source is switched off. Alternatively, the power supply of the phototransistor can be switched on before the light source is switched off. By delaying the switching on of the power supply of the phototransistor compared to the switching on of the light source, a significant current saving can be achieved.
