Abstract: A wireless spread-spectrum communication system for transmitting data includes a plurality of end point transmitters and at least one receiver. The end point transmitters transmit data via a frequency-hopped spread-spectrum signal where the transmitting signal is sent without the benefit of frequency stabilization. The receiver is responsive to the frequency-hopping spread-spectrum signals and includes a correlator and a signal processor. The correlator samples at least a first portion of a preamble of the signal and correlates the portion of the preamble with a known preamble pattern to determine a probability of correlation. The signal processor applies a Fast Fourier Transform algorithm to the signal in response to the probability of correlation to track a narrowband frequency of the signal based on at least a second portion of the preamble and to decode data encoded within the signal subsequent to the preamble.

Abstract: A roll-up door has a plurality of panels and a plurality of roller assemblies mounted to ends of the panels for mounting the panels in channels. At least some of the panels are formed of blow-molded thermoplastic material and have a relatively flat outside face and an inside face including ribs that extend longitudinally and transversely on the panel. A reinforced panel of thermoplastic material is made by blow molding a panel with a thermoplastic material to form a relatively flat outside face and a ribbed inside face, and with elongated channels along upper and lower walls thereof. The panel is trimmed while it is still warm to open the channels at one end. While the panel is still warm, reinforcing members are inserted into the elongated channels.

Abstract: A torque coupling for a rotor head of a rotary-wing aircraft is configured for rotation with a mast and for causing rotation of an attached yoke. The coupling has trunnions that rotate with the mast and extend generally radially. Pad-bearing assemblies each have a central member coupled to one of the trunnions with a laminated spherical bearing and have laminated pad bearings affixed to opposing sides of the central member. The laminated bearings have alternating rigid and elastomeric layers. A bearing mount is affixed to each pad bearing and is connected to a yoke for rotating the yoke with the mast. The pad-bearing assemblies allow for relative motion between each central member and the associated trunnion and between each central member and the bearing mounts through elastic shear deformation, and this allows for gimballing of the attached yoke relative to the mast.

Filed: 2008-01-03
Granted: 2012-09-11
Abstract: The hand tool (1) has a body (7), and a chuck (4) with an axial opening (3) on an axis of the tool. A tool element (2) is movable between a retracted position generally within the body, and an extended operative position wherein the tool element extends through the axial opening and chuck, the chuck having a stop (15) for blocking further extension of the tool element once in its operative position. A movable means (16) blocks the tool element against retraction when in the operative position, the movable means being dislodgeable when retraction is desired, to a position where the movable means no longer blocks the tool element against retraction. In the preferred embodiment, the hand tool has multiple tool elements (six for example), spaced around the axis of the tool. Each tool element, when extended, has a proximal end which abuts the distal end (14) of an axial post in the handle of the tool. The actuation mechanism (5, 8, 9, 10), in addition to moving the tool elements axially, preferably provides means (9, 10) for moving the distal end of the axial post radially, i.e. Away from axis and the tool element, for retraction of the tool element.multiple-bit hand tool with locking axial post

Abstract: An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.
