Abstract: A method for providing eavesdropping detection of an optic fiber communication between two users includes the steps of exchanging both data and probe signals through at least two channels (400, 500) between the users, exchanging probe signals (143) on one channel (500 or 400) between quantum probe signal terminals, extracting a key for authentication from the probe signals, and exchanging data signals (142) between transmission units on another channel (400 or 500). A first portion of the key generated by the quantum probe signal terminals is used to authenticate the terminals, wherein a second portion of the key is dedicated to define commutation occurrences of commutation devices adapted to commutate the use of the channels (400, 500) for data (142) and probe (143) signals, thus detecting an eavesdropping event (300) which triggers an alarm (750). A further portion of the key can be used to encrypt the messages.

Abstract: A battery power supply with extended shelf-life is composed of a plurality of batteries connected in series with a switching element and voltage booster. The switching element is composed of a transistor in parallel with a passive component that produces a voltage drop when the transistor is off. The voltage booster maintains an output voltage at set value when battery capacity deteriorates. A micro-controller is used to monitor voltage potentials to detect the presence of an external load. When no load is detected, all active components are disabled to conserve energy and avoid self-discharge.

Abstract: Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.
