Title:
VALVE WITH HANDLE INCLUDING SENSORS AND MEMORY
Document Type and Number:
WIPO Patent Application WO2002040914
Kind Code:
A9
Abstract:
A valve (10) with a smart handle (16) including a memory module (22) to log relevant data. A sensor (28) on the handle (16) determines when the valve (10) is open, and this triggers the start of timers (21) and recording of the "open" event in a log in the memory module (22). When the valve (10) is closed, the sensor (28) triggers stopping of the timers (21) and recording of the "closed" event in the log. The timer information is used to calculate the duration of the time "open" event, and this, together with the actual data and time of the opening and closing of the valve (10) are recorded in the log. Other relevant information, such as cylinder fill date, cylinder i.d. number, batch number, and patient name or account number may also be logged in the memory module (22). The log of the events and the corresponding dates and times may be used to prepare invoices for billing gas treatments, for inventory control, and for other record-keeping and control functions.
