摘要:
Methods for optical isolation in high peak power fiber-optic systems prevent damage to a facet within a fiber-optic isolator caused by back-reflected light from, for example, an optical amplifier. Preventing damage to the facet may include expanding a mode area of the back-reflected light and/or reducing a change in refractive index.

A trailer for transporting a liquid mixture having at least about 5% peracetic acid by weight includes a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure. One or more pressure relief valves are included in a wall of the tank within the external spill containment enclosure and configured to provide pressure relief to the tank at a pressure of between about 20%-50% of the maximum working pressure of the tank, thereby preventing over-pressurization of a reactive and decomposing fluid during a fire event. Wheels and a kingpin are affixed to the tank to enable transportation over public roadways.

Methods and apparatuses are proved which allow a wireless communication system using a smart antenna(s) to selectively cause a receiving device to switch its operative association from one transmitted beam to another available transmitted beam.
摘要:
A wireless device is coupled to a multi-sector antenna that includes a plurality of different sectors, any of which can be activated to transmit and receive in a desired direction specific to that sector. Optionally, an omnidirectional antenna is included for initially establishing a wireless connection with another wireless device, such as an access point. A parameter indicative of signal quality, such as throughput or received signal strength indication (RSSI) is determined by polling with each antenna sector to establish a prioritized candidate list. If a receive Trigger becomes active in response to a parameter falling below a threshold level, a new candidate sector is selected from the current list based upon a next-best signal quality. The directionality of the multi-sector antenna provides a substantially higher data rate compared to that of the conventional omnidirectional antenna.
摘要:
A waste receptacle is combined with an air freshener connected to the waste receptacle. Removal of a trash bag from the waste receptacle will cause a flow of air through the opening and air freshener to freshen the interior of the waste receptacle.
摘要:
In an implementation of directed wireless communication, a multi-beam directed signal system coordinates directed wireless communication with client devices. A transmit beam-forming network routes data communication transmissions to the client devices via directed communication beams that are emanated from an antenna assembly, and a receive beam-forming network receives data communication receptions from the client devices via the directed communication beams.

摘要:
An apparatus which comprises two compositions in contact with one another is described. The first composition comprises poly(1,4-cyclohexanedimethanol terephthalate) and a minor amount of poly(1,4-butylene terephthalate), while the second composition comprises an organic polymeric material. The use of the first composition allows for better adhesion between the two compositions. A process for making such an apparatus by first forming a shaped part from the first composition and then contacting that shaped part with the second composition is also described. The apparatus may be used to encapsulate electrical and electronic parts, and for other uses.
