摘要:
A system and method of monitoring and analyzing a plurality of attributes for an alarm condition is disclosed. The attributes are processed and/or unprocessed values of sensed conditions of a collection of a statistically significant number of statistically similar components subjected to varying environmental conditions. The attribute values are used to compute the normal behaviors of some of the attributes and also used to infer parameters of a set of models. Relative probabilities of some attribute values are then computed and used along with the set of models to determine whether an alarm condition is met. The alarm conditions are used to prevent or reduce the impact of impending failure.

A guardrail system for enhanced fall protection during the construction of a multi-story building subsequent to steel erection. The guardrail system includes an elongated bar comprising a first relatively short portion and a second relatively long portion that define an obtuse angle therebetween, and one or more apertures in both the first portion and the second portion of the bar. A plate is provided to be bolted to the first portion of the elongated bar in order to removably attach the bar to a perimeter frame element of a multi-story building frame with the second portion extending upwardly and inwardly into the building. Cable is then pulled through one or more apertures of the second portions of a selected plurality of elongated bars secured to a perimeter frame element to complete the guardrail system.

A retractable antenna assembly provides a substantially matched antenna impedance to a matching circuit (712) of a radiotelephone (200) whether the retractable antenna assembly is in the extended position or the retracted position. In one embodiment parts (304, 312) of a capacitor (714) are integrally formed on an upper portion of the retractable antenna assembly (206) such that when in the retracted position the capacitor (714) contributes to the overall antenna impedance. In another embodiment a capacitor (1302) is integrally formed on the lower portion of the retractable antenna assembly (900).

A method and apparatus for compression molding plastic articles including closures which includes providing coacting sets of tools including a first set for moving a core and core sleeve into engagement with a cavity mold on a second set of tooling. An actuator is provided between the first set of tooling and a fixed upper cam. The second set of tooling includes an associated actuator supporting the cavity mold and associated with a lower fixed cam. A nitrogen cylinder in the second set of tooling provides for control of the compression molding force. In a preferred form, a plurality of sets of tooling are provided in circumferentially spaced relation on a rotating turret supported by a central column. A common manifold supplies the pressure at accurately controlled pressure to each of the nitrogen cylinders. A control system is provided for monitoring and changing the pressure.

A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states.
摘要:
An apparatus for placing a mold charge into a cavity includes a pair of hubs mounted for rotation around parallel axes, a link connected between the hubs at positions off-center relative to the parallel axes and a blade connected to the link. Rotation of the hubs causes the blade to travel in an elliptical path relative to an extrusion orifice to cut mold charges from the orifice and place the mold charges into cavities passing beneath the blade. The apparatus preferably includes a drive member that simultaneously rotates both of the hubs to drive the blade relative to the extrusion orifice and cavities. The blade preferably includes an arm that extends into a cavity to place a mold charge into the bottom of the cavity for consistent and accurate placement of the mold charges from one cavity to the next.

An apparatus for placing mold charges into a mold of a compression molding machine includes a carrier, an arm pivotally mounted on the carrier and a mold charge pick-up cup on the arm at a position spaced from the carrier. The arm is pivotal on the carrier between a first position at which the arm is positioned to deposit a mold charge into a mold and a second position at which the mold charge pick-up cup is disposed to transport the mold charge. The carrier preferably is mounted for rotation around an axis. In some embodiments, a cam mechanism is coupled to the arm to pivot the arm as a function of rotation of the carrier. A spring may be coupled between the arm and the carrier for biasing the arm toward one of the first and second positions of the arm. In another embodiment, an actuator is carried by the carrier and coupled to the arm to pivot the arm with respect to the carrier. The arm preferably includes a passage for selective application of air and/or vacuum to the mold charge pick-up cup.
