A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and an arrangement for controlling the variable speed motor. The pumping system further includes an auxiliary device operably connected to the arrangement for controlling, and an arrangement for providing two-way communication between the arrangement for controlling and the auxiliary device. The arrangement for controlling is capable of receiving a parameter from the auxiliary device through the arrangement for providing two-way communication. In one example, the arrangement for controlling is capable of independently controlling the variable speed motor without receipt of a parameter from the auxiliary device. In addition or alternatively, the arrangement for controlling is operable to selectively alter operation of the motor based upon the parameter. In addition or alternatively, the arrangement for controlling is configured to optimize a power consumption of the variable speed motor over time based upon the parameters received. A method for controlling the pumping system is also provided.

An indicator system is provided that comprises an indicator positioned on a linear structure. The linear structure includes a portable linear structure having a proximal end and a distal end. The linear structure includes, for example, at least one of a hose, a fire hose, a cable, an electrical cable, a rope, a strap, and a tether device. The indicator includes directional markers positioned along the linear structure and oriented to identify a path to the proximal end. Each of the directional markers comprises a shape of an arrow, and a tip of the arrow points along the path to the proximal end. Additionally, the indicator can include a text string, for example, a text string comprising a word meaning “EXIT” or other similar term or phrase.

Devices, systems and methods for data transfer optimization. A computing platform may, for example, modify a first property of a communication network in relation to an analysis of a second property of said communication network and a property of a data item. For example, a processor or a modem may dynamically modify a payload header suppression module to suppress a static portion of a data packet or an acknowledgment packet.

Methods and apparatus for improving the upstream data transfer rate for a cable modem. A device that shares an upstream channel with other devices determines whether, based on particular data, an upstream channel data transfer rate can be improved over a current data transfer rate of a current upstream channel from the device to a remote system. If the upstream channel data rate can be improved, the device improves the upstream channel data transfer rate based, at least in part, on the particular data used to determine whether the data transfer rate can be improved.

The invention is an outdoor electrical cord connection protector. A pair of mated covers is at least partially hinged along a common access. Each mated cover provides a snap together wire entrance at one end and a wire exit at the other end of the snap together covers. Each wire entrance and wire exit opens to a snap together plug opening adapted to hold at least two mated plugs of an outdoor string of decorative lights. A seal can be affixed to each of the entrances of the protector. The seals help keep the protector water tight and well as protect against other environmental hazards such as dirt, bugs, etc.

A system for assisting physically challenged users in operating at least one device comprising a frame, at least one user operable switch lever mounted to the frame and having a generally large activation region, and at least one switch operatively connected between the at least one switch lever and the at least one device, and for energizing the at least one device. A tensioning device applies tension to the at least one switch lever, for holding the at least one switch lever under tension in a first position, but allowing the at least one switch lever to be moved by the user into a second position to energize the at least one device upon the user applying a force to the at least one switch lever in an opposite direction of the tension that exceeds the tension applied by the tensioning device, and for returning the at least one switch lever to the first position. Also included is a switch range adjuster for adjusting the at least one switch lever's range of motion between the first position and the second position.

A game ball including a casing and a lacing. The casing has a laced region. The lacing is coupled to the laced region of the casing. The lacing has an exposed surface comprised of an outer material that is compressible, resilient, and tactile. The outer material has a modulus of elasticity of between 14 and 170 kg/cm2 and a tensile strength between 100 and 650 kg/cm2. At least a portion of the lacing can have an exposed pebbled surface.

A configurable touch sensitive keyboard system is used to adjust or control the interface to a computer or other electronic device, particularly, for disabled individuals. The configurable touch sensitive keyboard system includes a touch sensitive keyboard having touch sensitive regions and a keyboard overlay having symbols corresponding to the touch sensitive regions. The symbols can be visually recognizable symbols or tactually recognizable symbols, such as Braille characters. A keyguard template is disposed on the keyboard over the overlay and includes keyboard access regions spatially separated on the keyguard. The keyboard access regions on the keyguard help disabled individuals to locate the touch sensitive regions for activation. Keyboard access cover members are used to selectively cover the keyboard access regions and the symbols and corresponding touch sensitive regions. By selectively covering the keyboard access regions using the cover members, the keyboard can be adjusted to suit the needs of a particular individual to improve the learning process and overall interaction with the computer or other electronic device.
摘要:
A tube testing connector adapted to engage a tube for pressurization thereof including a hollow body defining an entrance aperture at one end thereof for insertion of a tube to be tested and a pressure aperture defined in an end cap positioned at the other end of the body in sealing engagement with the body. The tester further includes a chamber having disposed therein retention gripping means to initially grip the inserted tube prior to pressurization. The connector operates such that when the tube is pressurized, the components of the tube testing connector exert an increased gripping force on the outer diameter of the tube to be tested so as to secure it in place during the test procedure.
