Toilet flushing systems installed in a toilet reservoir. A toilet reservoir stores a fluid that pours into a toilet bowl for carrying waste away from a toilet. Exemplary toilet flushing systems may include a flush sleeve having a sleeve bottom and sleeve top. The exemplary sleeve bottom may connect to a bottom of the toilet reservoir around a reservoir drain. The flush sleeve may be capable of being raised in a raised orientation such that the sleeve top is above the fluid in the toilet reservoir to prevent the fluid from entering the reservoir drain. Exemplary toilet flushing systems may include a flush sleeve actuator that lowers the sleeve top of the flush sleeve below a fluid level in the toilet reservoir to allow the fluid to flow through the flush sleeve into the reservoir drain.

The present invention discloses adjustable air duct sealing systems for obstructing airflow through portions of an air duct system. Such systems may include an adjustable frame assembly configured to allow changes to a perimeter of the adjustable frame assembly. Systems may also include an actuator pole connector configured to attach the adjustable air duct sealing system to an actuator pole. Systems may include two or more support arms such that each support arm connects the actuator pole connector to the adjustable frame assembly and each support arm moveably connects to the actuator pole connector to allow the support arms to adjust to changes in the perimeter of the adjustable frame assembly. Some systems also include a sheet cover configured across the adjustable frame assembly to obstruct airflow through at least a portion of the adjustable frame assembly.

A converged network is described. The converged network includes a distributed antenna system hub coupled to the communication lines for wireless communications, horizontal cabling to carry communication lines for wired communications and wireless communications and a remote socket. The horizontal cabling is a duct that carries the wired and wireless communication lines to convey the telecommunication signals within the building. The remote socket connects the wireless communication lines with a remote electronics unit. In addition, one or more antennas can also be coupled to the remote socket to convey analog RF electrical radiation from the remote socket over adhesive backed coaxial cabling to the indoor environment.

Converged in-building network

A cable routing system is described. More specifically, described is a cable routing system that includes a main fiber channel configured to receive a drop fiber to allow it to fit within the main fiber channel, where the channel is surrounded by a discontinuous segmented duct, and the duct comprises a continuous flange structure to provide support for the system as it is installed on or fastened to a wall or other generally flat surface.

A remote socket apparatus comprises a socket to receive a remote electronics unit. The socket is configured to house multiple media to connect to remote electronics housed in the remote electronics unit. The socket includes a socket interface configured to mate with a remote electronics unit interface. At least one of the socket and remote electronics unit further includes an actuation mechanism configured to connect the multiple media simultaneously. The remote socket apparatus can be utilized in a network that provides in-building wireless (IBW) communications and in a converged network that also provides wired in-building telecommunications.

Remote socket apparatus

A duct for distributing one or more optical fiber communication lines. The duct comprises an elongated main body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more optical fiber communications lines. The duct also includes a flange portion extending lengthwise adjacent the main body to mount the duct to a generally flat surface, wherein the duct further includes an additional fiber channel for distributing at least one additional optical fiber at least a portion of the length of the duct. The duct can also be formed as a two piece duct system. The duct can be utilized in a drop access location system for horizontal cabling in multi-dwelling unit (MDU) applications.

A system for installing communications in a hallway of a building comprises a duct having a conduit portion with a bore formed throughout and containing one or more communications lines and a mounting portion to mount the duct to a generally flat surface, the mounting portion including an adhesive disposed thereon, and a duct applicator tool to continuously receive the duct from a storage structure. The applicator tool includes a generally planar frame that supports at least one duct channel that receives the duct and provides a support surface that places a pressing force onto the duct as the duct is applied to the generally flat surface. The applicator tool includes one or more duct guides disposable on at least an end of the frame, where the one or more duct guides guide the duct from its storage structure to the at least one duct channel.

A low profile telecommunications fiber drop point of entry system for an interior room of an MDU, school, hotel, hospital, MTU or other commercial or residential location. The system includes a duct having one or more optical fiber communications lines and mountable to a first wall. The system further includes an access and storage structure at least partially disposable behind the first wall. The structure includes a first base unit having a first wall mounting portion and a first low profile cover, the cover being mountable over at least a portion of the duct. The first wall mounting portion includes a main port to fit over a hole formed in the first wall, the structure having a fiber slack storage area disposed between the first wall mounting portion and the first cover. The structure further includes an extension arm mounted to the first wall mounting portion and extending behind the first wall, the extension arm supporting a carrier configured to hold an optical fiber connector coupling device. A first optical fiber from the duct is terminated in a first optical fiber connector that is mounted on the connector coupling device.

A test socket for temporary connection of a ball grid array integrated circuit device to a test circuit includes an array of contacts each including two cantilever arms biased toward each other and terminating in tips adapted to capture one ball of the device.

Top load socket for ball grid array devices

A contact retention module for a test socket includes mating gear-like teeth formed of alternating projections and valleys. The projections of one module half close the valleys of another module half to produce pockets which retain and guide contact terminal ends within the pockets.

Socket for tab testing

A burn-in socket for land grid array devices or ball grid array devices includes a receptacle having an array of terminals for accepting and contacting the device and an outer shell which is actuated by rotation of the shell to capture the device and provide a force to ensure electrical contact between the device and the terminals.
