摘要:
A bus inversion method and system for capturing a previous state of a bus and its corresponding inversion bit prior to transmitting new information over the bus. The new information, state of the bus and associated inversion bit are used to determine whether the new information should be inverted before being transmitted.

The present invention is a safety hook (12, 12′) having a wire spring latch (26, 26′). The wire spring latch (26, 26′) is a wire loop pawl. The safety hook (12, 12′) is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends (14, 14′, 16, 16′), a chain link securing end (14, 14′) and a hook opening end (16, 16′), respectively. The wire loop pawl (26, 26′) is preferably a rod of elastically deformable material, bent to form an open loop (28, 28′) and bent-over ends (32, 32′, 34, 34′) about which the pawl (26, 26′) pivots with respect to the body (12, 12″) of the safety hook (10, 10′) when the latch (26, 26′) is deformed and forced away from a distal end (38, 38′) of the hook opening end (16, 16′) of the safety hook (10,10′). The bent over ends (32, 32′, 34, 34′) of the wire loop pawl (26, 26′) are not coaxial. The wire loop pawl (26, 26′) may be deformed in such a way as to open the safety hook (10, 10′), but the latch (26, 26′) is heavily spring biased up against an inside (37, 37′) of the distal end (38, 38′) of the safety hook (10, 10′).

An automated storage and retrieval system includes an accessor device to magnetically hold a stored item while the item is transported within the system. To sense the presence of a magnetically attractable label on the item, the device generates a pulsed signal having a first strength. The reluctance of the magnetic field is compared with a base value; if the comparison indicates that a label is present, the device generates another pulsed signal having a greater strength to "lock" the item against the accessor. The device then generates another pulsed signal having a reduced strength to maintain and hold the item against the accessor during transportation. Less power is used and, therefore, less heat generated.

The disclosure comprises a pair of inflatable substantially inelastic lobes. A single lobe can be mounted on each of the rear trailer doors of a standard tractor-trailer unit. Each lobe can be inflated or deployed to provide an aerodynamic substantially planar contour extending rearwardly of the rear end of the vehicle. The aerodynamic shape of the lobes with stable and substantially planar external surfaces for air to pass over can be created by a series of internal cords and flag sets extending substantially horizontally and vertically in an array from one side of the lobe to the other side of each lobe. When the lobes are deflated, the trailer doors can be opened and latched to the side of the trailer in a conventional manner.

A tube assembly includes a head component that may be weighted. The tube assembly is formed by welding a head tube to a main tube using a die heated by radiofrequency energy. A head lumen in fluid communication with the main tube and seal between the head lumen and a chamber of the head component are formed generally simultaneously when the head tube is welded to the main tube. At another step, weights or filler members are inserted into the chamber. A rounded tip of the tube assembly is formed by forcing a distal end of the head tube into a die that is heated by radiofrequency energy. Outlet openings in fluid communication with the head lumen are formed in the head tube using a punch device. An inlet adaptor of the tube assembly is welded to main tube using a die that is heated by radiofrequency energy.

A helicopter external cargo suspension system (12) has load sensors (19,20) at each suspension point for sensing the magnitude of a load (32) at each suspension point. A delay period (FIG. 6) is determined based on the magnitude of the load, and a load is released if one of the following failure modes occurs for a period which exceed the delay period: one of the suspension points is unloaded, the magnitude of the load exceeds a maximum threshold magnitude, or if the distribution of the load, as indicated by the difference in magnitude at each suspension point, exceeds a difference threshold magnitude. If the magnitude of the load is below a minimum threshold magnitude, the load will be carried by one of the suspension points in response to a failure of the other suspension points.Alternatively, the load information is converted from crisp values to fuzzy inputs (700) wherein the detected values are fuzzified by assigning a membership weight at discrete points or segments on a normalized scale; a new mode fuzzy output (707) is provided by applying a compositional rule of inference (705) across each fuzzy input (702) and a composite mode selection rule base (710), the new mode fuzzy output (707) is converted into a crisp output by taking the weighted sum of the membership weight at each point on the normalized scale in excess of a threshold value (712), and new mode is determined by comparing the new mode crisp output to a set of new mode membership ranges (FIGS. 8e and 9e).
摘要:
A flexible connection joint for inflatable structures such as life rafts, evacuation slides, and the like, includes a flexible connection member to join walls of the inflatable structure together. The flexible connection member includes first and second strip portions that are bonded together at one end to from three legs that can be joined to two or three walls of the structure or to other connecting elements or strips. In this manner, a tensile force acting on at least one of the walls of the structure causes generation of shear forces between the flexible legs and walls to thereby resist their separation.

A portable digital voice recorder is interfaced for data communication with a personal computer. The personal computer is connected by a data communication network with other devices such as other personal computers, a central dictation system, and/or a voice mail system. Voice data files previously generated by dictating information into the portable recorder are stored in the portable recorder and then uploaded to the personal computer. The voice data files include header data associated with the voice data files. The personal computer reads the header data and automatically forwards the voice data file to one or more of the other devices on the basis of information contained in the header data.
