摘要:
The control software of a central office-installed ringback test device is augmented to allow a craftsperson to test the operability of a caller identification, call-waiting (CIDCW) class of service of a line, without participation of another technician at the central office. Rather than instructing the craftsperson to go back in-hook, the SASS's microcontroller maintains the trunk circuit through which the incoming call is coupled to the SASS in a suspended, continuously monitored state, so as to effectively busy out the calling line. The SASS then places a return call to the calling number by way of the ringback line, which by-passes the trunk, to the central office switch. If the line circuit from which the call is being placed is equipped with CIDCW class of service, the incoming call from the SASS will exercise its functionality--including providing a ringing signal back to the SASS, and an indication to the calling technician of another call, including the originating telephone number of that call--but it will not return a busy tone to the SASS. If the SASS receives busy tone, it knows that the line of interest is not properly equipped with CIDCW class of service.

System and techniques for enhanced electronic navigation maps for a vehicle are described herein. A descriptor set-up message may be received at a network controller interface (NIC). Here, the descriptor set-up message includes an ethernet frame descriptor. The NIC may then use the ethernet frame descriptor to transmit, across a physical interface of the NIC, multiple ethernet frames, each of which use the same ethernet frame descriptor from the set-up message.

A surgical stapler having a hollow shaft 10 and a tube 92 slidable axially within the shaft between a forward position wherein one end 96 of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position wherein the end of the locator tube is retracted within the shaft. A surgical staple 40 straddles the tube 92 and is slidable thereon forwardly towards an anvil 24 against which the staple may be deformed to staple together the opposite edges of the puncture site. A cam mechanism drives the staple forwardly along the tube 92 into deforming engagement with the anvil and at the same time retracts the tube into the shaft in time to allow the legs of the staple to close onto the puncture site.

A method of forming an electrically-conductive pattern includes selectively electroplating the top portions of a substrate that corresponds to the pattern, and separating the conductive pattern from the substrate. The electroplating may also include electrically connecting the conductive pattern to an electrical component. Conductive ink, such as ink including carbon particles, may be selectively placed on the conductive substrate to facilitate plating of the desired pattern and/or to facilitate separation of the pattern from the substrate. An example of a conductive pattern is an antenna for a radio-frequency identification (RFID) device such as a label or a tag. One example of an electrical component that may be electrically connected to the antenna, is an RFID strap or chip.

A device for locating a puncture hole in a liquid-carrying vessel such as a blood vessel comprises a hollow tube 92 having front and rear openings respectively at opposite ends of the tube to allow the tube to slide along a guidewire passing through the tube. The front opening 96 comprises a first portion 96A for slidably accommodating the guidewire and a second portion 96B to allow liquid from the vessel to flow back through the tube. The device is configured, e.g. by a constriction 96C, such that a guidewire at least above a certain diameter in the first portion 96A of the front opening is restrained against moving into the second portion 96B. Alternatively, the first and second portions 96A, 96B of the front opening may be independent of one another.

After the main ball drop of a bingo game, a player may be given a free extra bingo number. A probability of awarding a free ball may be determined, at least in part, according to a desired paytable percentage for the bingo game (or vice versa). Some implementations of the invention provide multi-card bingo games. A player may be required to hit a predetermined pattern on more than one bingo card in order to obtain a progressive award. The number of hits in the pattern(s) and/or the number of bingo cards involved may be determined according to a desired progressive award size and/or a desired probability of obtaining the progressive award. Players may have an opportunity to purchase one or more additional bingo numbers after the main ball drop of a bingo game. A player may be provided the option of purchasing a block of more than one additional bingo number after the main ball drop. The player may be offered such a block at a discount, as compared to the price for purchasing the additional bingo numbers individually.

Methods and devices are provided for closing a puncture wound. In one exemplary embodiment, a puncture closure device is provided having an elongate tubular body that is disposable through a puncture in tissue and that includes proximal and distal portions. The proximal portion can be adapted to expand to form proximal wings upon rotation of the elongate tubular body, preferably in a first direction. The distal portion can be adapted to expand to form distal wings upon rotation of the elongate tubular body, preferably in a second, opposite direction. The proximal and distal portions can also be adapted to be moved toward one another as they expand upon rotation. As a result, the proximal and distal wings can engage tissue therebetween.

A process, system and apparatus is provided for passivating carbonaceous material against spontaneous combustion. The process involves drying the carbonaceous material in a low oxygen environment and pre-conditioning the carbonaceous material by contacting it with volatile matter contained in a countercurrent gas stream. The volatile matter coats the particles of dried carbonaceous material and plugs the micropores of the dried carbonaceous material, thereby passivating it against adsorption of water and oxygen, and thus spontaneous combustion. The pre-conditioned dried material then undergoes devolatilisation at temperatures at which volatile matter is evolved. The evolved volatile matter mixes with the countercurrent gas stream and is used to pre-condition dried carbonaceous material located upstream.
