Abstract: Disclosed are embodiments of a round floor grommet and a rectangular floor grommet. These floor grommets can be constructed in any desired shape other than round or rectangular. Frame portions that hold foam pieces are joined together to form a primary slit in the floor grommet. Cross slits can also be formed in the foam material. The foam is a semi-closed cell foam that is constructed from PVC and nitrile butadiene rubber which has superior sealing effects since the foam can conform around objects passing through the slits in the floor grommet and seal any flow of air through the slits.

Abstract: Disclosed is a sensor floor tile that utilizes a RF frequency transmissive disk that transmits sensor data from sensors located in a plenum of a raised floor system. An antenna is located adjacent to the disk so that sensor signals can be transmitted from the sensor located in the plenum under the floor tile to a wireless receiver located in an elevated location in a data center room, a computer room, a clean room, an office space, etc. A network connection can also be provided by the antenna when the antenna is connected to a router in the plenum.

Abstract: A method for enhancing the cooling efficiency of a computer room air conditioning unit, in a data center, is provided. Raised floor panels are carried on a pedestal support system. The floor panels divide a data center, into upper and lower plenums. A cold aisle is includes air-grate floor panels. The computer room air conditioning unit is operated to condition a heated hot aisle return air flow. A server rack has a front, a back, and side rack support frame members. The support members define an interior server compartment. At least one damper door frame has a top, a bottom and side members. The door frame members define at least one open air flow panel portion. A series of horizontal damper blade members are pivotally mounted in the open panel portion. The damper blade members are pivoted to direct a stream of the conditioned air flow over heat generating components contained in the interior server compartment in order to elevate the temperature of the heated return airflow at the air conditioning unit.

Abstract: Disclosed is a facilities management system that utilizes embedded maps in nested facilities management devices. The facilities management devices are connected to a network and are linked in map images that indicate the location of the facilities management devices, as well as the locations of sensors. In addition, the links indicate the existence of an alarm condition, so that users can drill down on the links to locate a sensor that has created the alarm condition. The facilities management system utilizes various management systems and various protocols to provide a wide range of options for facilities managers.

Abstract: Disclosed is a monitoring system that is capable of monitoring data from sensors using both wired and wireless communication links. A wide variety of sensors can be utilized with various monitoring systems through the use of an interface device that translates the communication protocol of the sensors to the communication protocol of the monitoring device. In this fashion, the sensors can be mass produced at lower prices to reduce the overall cost of the sensors, as well as providing a wide variety of sensors. Interface devices can also be mass produced, which also lowers the overall cost of the sensing system.

Abstract: Disclosed is a leak detection cable that has an outer jacket layer and a four wire construction in a flat wire configuration that is twisted in a helix. Detection cables are disposed on the exterior surface adjacent openings of the jacket to allow for detection of aqueous fluids. The wire is twisted in a helix to allow adjacent detector wires to easily detect aqueous fluids. Disparate materials are used for the jacket and the coatings of the wires, to allow the jacket to be easily removed from the wires without affecting the integrity of the coatings of the wires. The four flat wire configuration is sized and spaced for easy connection to an insulation displacement connector.

Abstract: Disclosed are aqueous chemical leak detection cables that provide protection to sensor wires by using a conductive polymer coating that is resistant to corrosion by aqueous chemicals. In addition, non-conductive, liquid pervious layers may surround one or more of the sensor wires to assist in preventing false detection of a aqueous chemical leak as a result of various non-liquid contaminants. The non-conductive, liquid pervious layer may comprise braided, non-hydroscopic, non-conductive fibers, or a continuous, non-conductive pervious coating.

Abstract: A fluid detection cable is described for use in detecting the presence of leaks in areas where a particular fluid is not desired. Sensing leads in the fluid detection cable have a center conductor that may be surrounded with a non-porous conductive polymer coating that protects the conductors from corrosive fluids. A non-conductive polymer at least partially surrounds the sensing leads so that a fluid transmission path allows fluid to contact the conductive polymer. The non-conductive polymer may be porous to provide a fluid transmission path. Fluid transmission paths may also be structurally formed in the non-conductive polymer. The non-conductive polymer protects the sensing leads from false alarms that would occur if the conductive polymer were to be in contact with non-fluid conductive surfaces. The cable may also include monitor leads that are conductors coated with, or embedded in, non-conductive non-porous polymers.
