Abstract: A processing system employs a processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes. Sensors sense various aspects of the processing. Information regarding performance of the process and/or materials may be stored, for example a hole-by-hole or a workpiece-by-workpiece basis, allowing validation of processing. Information also allows dynamic operation of the processing tool. Analysis of response relationships (e.g., pressure or force versus position or distance) may provide insights into the process and materials, and/or facilitate the real-time feedback including control, alerts, ordering replacement for consumable components.

Abstract: Methods to establish communication between a first and second device via at least one intermediate device comprise, at the first device, generating an offer data packet comprising a second device address, which includes a first identifier indicating a public key associated with the second device; transmitting the offer data packet to a first intermediate device for transmission to the second device based upon the address of the second device; receiving an answer data packet via the first intermediate device, the answer data packet including network information associated with the second device; establishing a communication channel with the second device based on the network information received; receiving over the communication channel a first handshake data packet including a public key; calculating a second identifier based upon the public key; comparing the first identifier with the second identifier; and warning if a relationship between the first identifier and the second identifier is not an expected re

Abstract: There is described an apparatus and method for inspecting and optionally sorting gemstones. The apparatus includes a nozzle or array of nozzles operatively connected to a vacuum pump such that a gemstone located generally underneath one of the nozzles will be supported against that nozzle by air pressure when a vacuum is applied above the nozzle. A drive system moves the nozzles along a path past a gemstone pick-up location so that a gemstone can be picked up by each nozzle as that nozzle passes the pick-up location. One or more measurement devices are located on or near the predetermined path and configured to measure at least one property of the gemstone. One or more ejection locations are provided on the path at which the vacuum applied to each nozzle is reversible to eject the gemstone from that nozzle. The apparatus may also include a plurality of dispensing bins into which the gemstones are dispensed. The bin into which each gemstone is dispensed is chosen in dependence on the measured property.

Abstract: The invention relates to a light source (10, 12) comprising a light emitter (20) arranged inside a translucent outer envelope (30, 32). The light emitter comprising a light emitting device (40) and comprising a translucent inner envelope (50) at least partially surrounding the light emitting device, the translucent inner envelope comprising a diffuser. A diameter (di) of the translucent inner envelope is smaller than a diameter (do) of the translucent outer envelope. The translucent outer envelope is connected to a base (60) not being translucent. The translucent outer envelope further comprises a symmetry axis (S). An imaginary base-plane (P) is defined substantially perpendicular to the symmetry axis (S) and intersects with a connection point (C) being part of the translucent outer envelope.

Abstract: A nut plate assembly includes a nut retainer and a bushing for expanding a tubular body of the retainer. The retainer assembly is used to cold work an opening of a workpiece in order to fix the nut retainer assembly relative to the workpiece. A nut can be snapped into the retainer. A method of installation includes passing a mandrel through the bushing to radially expand the bushing into a tubular body of the retainer. The tubular body is compressed between the workpiece and bushing as the bushing is displaced radially causing corresponding radial displacement of the tubular body. The expanded bushing applies pressure to the tubular body for a desired fit between the nut retainer and workpiece.

Abstract: A sanitary disposable writing instrument for minimizing the transfer of bacteria, viruses and/or chemicals from one person to another including a strip of flexible holding material, a writing implement removably secured to the flexible holding material, and a writing tip associated with the writing implement. At least a second writing instrument can be provided to form a series of removably secured writing instruments wherein removal of one writing instrument from the series causes a next writing instrument to be positioned for removal from the series. Combination dispenser and holding members for dispensing the series of writing instruments in a sanitary manner is also provided. The holding members can be mounted on either a vertical or horizontal support surface and can receive replacement dispensers therein.

Abstract: A system for enabling interactive communications between participants is described. The system includes a website, a first web-browser client, a second web-browser client, a synchronous communication channel, a spontaneous transmit message and a spontaneous receive message. The first web-browser client corresponds to a first participant accessing the website and receiving computer instructions from a first participant. The second web-browser client corresponds to a second participant accessing the website and receiving computer instructions from a second participant. The synchronous communication channel between the first browser client and the second browser client is configured to enable near real-time communications between the first participant and the second participant. The spontaneous transmit message is transmitted from the first web-browser client and the spontaneous transmit message received by the second browser client.

Abstract: At least one embodiment generally relates to an installation assembly for an opening in a workpiece that includes a swaged collar, an inner member, and an outer member. The swaged collar has a first end, a second end, and a main body extending between the first end and the second end. The main body includes an inner surface defining a passageway through the collar. The inner member has a mandrel section for expanding the outer member. The inner member is used to expand the outer member and to keep the outer member in an expanded state.

Abstract: A processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes includes an expansion assembly with a plurality of elongated expansion segments. A first band and a second band couple the expansion segments into an array with the expansion segments circumferentially distributed about a longitudinal axis, with a passageway extending between the arrayed segments. The processing tool may include a tuning assembly that allows a radial expansion amount of the expansion assembly to be adjusted without altering a stroke length of a drive member of the processing tool. Sensors may sense various aspects of the processing performed by the processing tool to enable analysis and storage of information regarding performance of the process and/or materials processed by the processing tool.
