20080246599 | Hand hygiene compliance system - A system and method of encouraging compliance of hand hygiene in an environment where users move from zone to zone and are required to perform hand hygiene between the zones. Users carry a wearable zone sensor which detects zones, detects hand hygiene actions, logs time of changing zones, and hand hygiene actions. The wearable sensor can be integral with a wearable hand hygiene product dispenser and/or can operate in cooperation with a fixed dispenser configured to transmit hand hygiene actions to the wearable zone sensor. The wearable zone sensors are configured to be useable anonymously or to be associated with a user identifier, and to interface with a central computer via a docking station or communication interface to transfer data for later analysis. | 10-09-2008 |
20100117836 | HAND HYGIENE COMPLIANCE SYSTEM - A system and method of encouraging compliance of hand hygiene in an environment where users move from zone to zone and are required to perform hand hygiene between the zones. Users carry a wearable zone sensor which detects zones, detects hand hygiene actions, logs time of changing zones, and hand hygiene actions. The wearable sensor can be integral with a wearable hand hygiene product dispenser and/or can operate in cooperation with a fixed dispenser configured to transmit hand hygiene actions to the wearable zone sensor. The wearable zone sensors are configured to be useable anonymously or to be associated with a user identifier, and to interface with a central computer via a docking station or communication interface to transfer data for later analysis. | 05-13-2010 |
20110092839 | MASK AND METHOD FOR USE IN RESPIRATORY MONITORING AND DIAGNOSTICS - Disclosed herein is a mask to be worn by a subject on its face for use in respiratory monitoring and/or diagnostics. In general, the mask comprises at least one transducer responsive to sound and airflow for generating a data signal representative thereof, and a support structure shaped and configured to rest on the subject's face and thereby delineate a nose and mouth area thereof. The support structure comprises two or more outwardly projecting limbs that, upon positioning the mask, converge into a transducer supporting portion for supporting the at least one transducer at a distance from the area, thereby allowing for monitoring via the at least one transducer of both sound and airflow produced by the subject while breathing. The limbs may, in some examples, have along at least a portion thereof, an inward-facing channel defined therein for channeling toward a given transducer, air flow produced by the subject while breathing. A method is also disclosed for remotely diagnosing a breathing disorder of a subject. | 04-21-2011 |
