Abstract: A virtual health-care electronic commerce community includes a network to communicate information relating to the community; one or more patients coupled to the network; one or more treating professionals coupled to the network; and a server coupled to the network, the server storing data for each patient and performing patient data visualization in response to a user request.

Abstract: A system (100) and method for determining the air leakage of a space (102) in a building is disclosed. The system (100) comprises a processor (120); a source (130) of compressed air; a pressure sensor (150) configured to measure the pressure of air residing within the space (130) and to provide background pressure signals to the processor (120); a nozzle unit (140) for metering the supply of a pulse of compressed air from the source (130) and for directing the pulse into the space (102) and a source pressure sensor (132) configured to measure a transient pressure during the pulse and to provide a transient pressure signal to the processor (120), wherein the processor (120) is configured to determine the air leakage based on changes in the background pressure signals and from the transient pressure signal. This provides a more reliable and cost effective way of measuring air leakage.

Abstract: Secure printing apparatus, for example printing apparatus of a postage meter, is disclosed in which an ink jet print head with integral ink supply is removable by a user of the apparatus. In order to maintain security of the apparatus, a parking station remote from a printing station is provided for the print head and removal of the print head can be effected only at the parking station through an aperture in a secure housing at the parking station. When the print head is moved to the parking station electrical connection to the print head are disengaged from the print head and means are provided to prevent access to those electrical connections at the parking station.
