Abstract: An airflow monitor and breathing device having a flexible main band, an elongate main lead wire, and a nasal lead wire set, wherein the flexible main band, the main lead wire, and the nasal lead wire set cooperate to monitor the wearer's inspiration and expiration. An optional oral lead wire may be provided to extend down vertically from the nasal lead wire set towards the wearer's mouth. Also, an airflow breathing device having an airflow tube set, a flexible main band, and nasal tube set is provided to deliver a desired gas to a user.

Abstract: A high resolution position sensitive radiation detector for analyzing radiation emanating from a source, constructed of a thin plate having an elongated slot with conductive edges acting as a cathode, a charged anode wire positioned within 0.5 mm adjacent the source and running parallel to the slot and centered therein, an ionizable gas ionized by radiation emanating from the source provided surrounding the anode wire in the slot, a helical wire induction coil serving as a delay line and positioned beneath the anode wire for detecting gas ionization and for producing resulting ionization signals, and processing circuits coupled to the induction coil for receiving ionization signals induced therein after determining therefrom the location along the anode wire of any radiation emanating from the source. An ionization gas of 70% Ar, 29% Isobutane, 0.6% Freon 13BI, and 0.4% Methylal is used.
