摘要:
The invention relates to a fire-resistant composition containing at least one star polyamide and a flame retardancy system comprising a phosphinate and a melamine reaction product. The inventive composition can be used to produce elements having a low flame-spread rating upon combustion as well as satisfactory mechanical properties. Said composition is particularly suitable for producing molded elements that are used in the field of electrical and electronic connector technology.

A system for treating abnormalities of the cardiovascular system includes a stent having a plurality of movable crown portions. When the stent is expanded, the crown portions move to a diameter recoil prevention position. One embodiment of the invention includes crown portions that translate from a concave to a convex configuration with respect to the strut portions of the stent during expansion of the stent. Another embodiment of the invention includes a method reducing diameter recoil of stent upon expansion of the stent.

A method for predicting maintenance in a refrigeration system includes counting occurrences of a compressor operating event and calculating a cumulative total of the compressor operating events. The method also comprises comparing the cumulative total with an operating threshold and estimating a time period until the cumulative total exceeds the operating threshold. The method may be executed by a controller or stored in a computer-readable medium.

A system is provided for wireless video entertainment including sources of video, audio and/or data signals. A server processes and stores the video signal prior to transmission to a personal electronic device (“PED”) of a user. Transmission to the PED is wireless via a multi-band RF access module positioned in close proximity to the PED. The PED may be a laptop computer, cell phone, touch display unit or other device capable of receiving and processing a digitized video signal. The access module includes a RF power combiner for unique bundling and isolation of a plurality of video signals throughout the transmission process. An audio signal may be synchronized or isochronously transported with a video signal and transmitted via an audio module to a wireless audio receiver, such as a headset. Further, data signals for Internet and email use are provided. System and GUI software facilitate operation of the system.

A retroreflective article having at least one valve is disclosed. Each valve may include a channel extending from a first major surface to a second major surface of the retroreflective material, and at least one movable member proximate the channel. The at least one movable member is movable between a closed position and an open position. When in the closed position, the at least one movable member obstructs at least a portion of the channel. A method of making a retroreflective article having at least one valve is also disclosed.

Interfaces are provided which integrate mistake-proofing concepts in a way easily understandable by the operator and easily configured by a manufacturing engineer. As mistake-proofing concepts are developed tables are populated and associated with specific assembly processes. Sensors are employed to monitor parts selection and tool usage. Sensors used for tool use and parts selection, error messages and actions to be performed or monitored are all defined and related in the tables and in turn to specific assembly orders. The tables are also populated with logic pointers, which are referenced by a Process Logic Control (PLC) unit that has been programmed to recall and carry out infinitely variable monitoring or control of the assembly process. For example when a particular order has been identified to the PLC by way of a scanned barcode or other means, a bill of material and assembly sequence is provided to the operator by appropriate means such as a CRT monitor. Parts bins and assembly points may be indicated by visual or other means to indicate parts and tools to be used and assembly points. Sensors determine when the proper part has been selected for the particular assembly step and/or whether the appropriate tool is used. The PLC then provides feedback to the operator to indicate whether all necessary steps have been accomplished in the proper order, with the proper parts using the proper tools. The PLC will provide the operator with understandable error messages indicating when a step has been improperly completed. The PLC can also control stops on the line to prevent the assembly from moving forward until all steps have been completed according to the specific order program. An override means may also be provided to bypass the PLC controls in which case an error log is compiled and an automated message is sent to supervisory personnel indicating that the system was overridden by the operator and follow up action is required.

A pole mounting system mountable on a footing and used for supporting vertical structures. The system includes a pole having a lower end terminating in a lower edge, a base plate having an opening, and ears attached transversely to the base plate adjacent to the opening. The pole is secured within the opening in the base plate to allow the base plate to provide improved structural support. The ears are vertically aligned with the pole and are welded to the pole along their upper edges. The lower edge of the pole is also welded to the base plate. The ears can be integrally formed from the base plate in a process whereby, first, interconnected slots are cut into the base plate such that the slots define the ears, and second, the ears are bent upward so that the ears can received the pole. No additional supports or weld pieces are necessary, so that the improved mounting system may provide sufficient support with two pieces, the pole and the base plate.
