[0042] FIGS. 3B-3C show window 350 , having one or more sensors 71 , 72 , which may be mounted in one or more positions relative to the window 350 . As shown in FIG. 3B, the sensors 71 , 72 in position 102 , may be mounted so as to be in a vertical position, so as to be facing downward. The sensors 71 , 72 may be mounted in position 104 so as to be in a vertical position as to be facing upward. The sensors 71 , 72 in position 106 may be mounted in a horizontal position. The sensors 71 , 72 may be mounted in position 105 to monitor a lock on the window 100 . One of more of the sensors 71 , 72 may be mounted in positions 102 , 104 , 105 , and 106 to determine whether the opening of the window 100 is from inside the home or building, or from the outside. Although sensors 71 , 72 are shown as mounted in positions 102 , 104 , 105 , and 106 in FIG. 3B, these are merely examples of the number of sensors and mounting positions for the window 350 that may be used. For example, one sensor may be mounted (e.g., mounted in position 356 ), or two sensors may be mounted, such as in positions 354 and 356 .

[0046] The sealant 12 (see FIG. 4) seals the wound area such that contaminants cannot enter the wound area from the outside and also to prevent exudates from leaking out of the wound dressing where they may create an infection hazard to others. In a preferred embodiment the sealant 12 is a flexible gel which is applied over the top of the pouch 1 after it is placed inside the wound. The gel prevents leakage in either direction (e.g., leakage is intended to mean not only exudate leakage from the wound, but also air leakage from outside the dressing). By sealing the dressing with the gel, the environment surrounding the wound becomes more stable.

[0012] In addition to the need for efficiency and ease of use is the need for security when sending, storing, or printing print jobs. Early in the life of the Internet, the need for securing an organization's local network from tampering, stealing, or vandalism by outsiders became very obvious. A type of gateway called a firewall was developed to meet this need. The firewall is designed to be a single, well-controlled access point between the outside, global, or wide-area network and the inside, local-area network. By carefully restricting the types of network traffic and the destinations where that traffic can flow, the firewall can provide effective protection.

[0079] The printer polling device 100 may periodically poll the spooling server 50 to identify a print job associated with the printer polling device 100 . Security is achieved by the fact that the printer 120 is not passively accepting any and all connections from the outside. The printer polling device 100 is initiating connections to a specific, trusted location, the spooling server 50 .

In another embodiment of the invention, the reader in the lock is sensitive to the direction from which the code is transmitted by the universal key, so that the code will only be detected by the reader associated with the lock in the door when the user carrying the universal key is outside the door but not when the user is inside the door. This prevents the door from being inadvertently unlocked when the user carrying the universal key passes close to the inside of the door. In addition, the lock may be configured to automatically unlock when the door is approached from the outside and will automatically lock when the user walks away from the door on the outside and travels beyond the receiver read range.

As used herein, the term “extranet” is a computer network that allows controlled access from the outside. An extranet can be an extension of an organization's intranet that is extended to users outside the organization that can be partners, vendors, and suppliers, in isolation from all other Internet users. An extranet can be an intranet mapped onto the public Internet or some other transmission system not accessible to the general public, but managed by more than one company's administrator(s). Examples of extranet-style networks include but are not limited to:

[0007] This disclosure addresses dynamically maintaining areas of a building at a positive or negative pressure with respect to other areas of the building. Dynamic pressure balancing helps to prevent particulates in the air of one area from reaching another area in the building, so that air from a negatively pressurized area may be prevented from reaching a positively pressurized area. Such a system is specifically advantageous for a building that utilizes different areas for different purposes. For example, in a manufacturing facility it is desirable to prevent air particulates from reaching “clean” environments. Air from welding or press areas containing various particulates, for instance, could adversely affect a product if the particulates reach product assembly or paint areas. In such a building, positively pressurizing the areas of the building with respect to the outdoor environment, may also prevent dust and other particulates from entering into the building from the outside.
