Abstract: In coding of an audio signal, coded signals with low quality and bit rate on the one hand and coded signals with high quality and bit rate on the other hand are transmitted to a decoder. At first, the audio signal is coded with low bit rate and is transmitted to the decoder before an additional coded signal is transmitted to the decoder, which either alone or together with the first coded signal upon decoding thereof provides a decoded signal with high quality within the decoder. In this manner, a low-quality decoded signal is generated first in the decoder before decoding of the high-quality signal is possible.

Abstract: Deflagration to detonation transition (DDT) detonators are provided which are essentially free from primary explosives. The detonators utilize an intimate mixture of a large particle sized porous, powdered explosive such as PETN, and smaller particle size, high-burn-rate, pressurizing initiator such as a mixture of potassium picrate and potassium perchlorate. The smaller particle sized pressurizing initiator is located within the interstitial spaces of the larger powdered explosive. This mixture is able to reliably initiate an adjacent transition portion, or base charge while reducing the need for heavy confinement. The mixture can also be used directly in surface detonator applications. Improved performance and safety during manufacture of detonators is achieved.

Abstract: In an improved connector assembly, a male pin is inserted into a proximal end of a female contact which conductively engages the pin at a distal end, providing a folded signal path geometry. As a signal propagates in a first direction along the male pin, it generates a first magnetic field of a first orientation about the male pin. At the contact point, the signal reverses direction and generates a second magnetic field of a second orientation opposite the first orientation about the female contact. Their respective opposed orientations cause the magnetic fields to substantially cancel in the region of magnetic interaction. Any remaining electric fields are contained by grounded shielding in the female contact cavities. This configuration mitigates the effect of crosstalk between adjacent signals in the connector, and reduces the effective path length of the signal.

Abstract: A method of built-in self testing field programmable gate arrays (FPGAs) including the programmable logic blocks, the programmable routing networks and the programmable input/output cells or boundary ports at the device, board or system level includes testing the programmable logic blocks, reconfiguring a first group of he programmable logic blocks to include a test pattern generator and an output response analyzer, and configuring the programmable routing network into groups of wires under test. This step is followed by generating test patterns propagated along the wires under test and comparing the outputs utilizing the output response analyzer. Based on the result of the comparison a pass/fail test result indication is routed to the associated boundary port. The results from a plurality of output response analyzers can be compared utilizing an iterative comparator in order to reduce the number of boundary ports required during testing.

Abstract: A fireplace has a firebox with a controllable outside air vent to provide a source of cooler air for mixing with and modulating the temperature of the air heated by the fireplace. The air vent is vertically formed between a combustion chamber and a surrounding shell so that a connective current causes the air to flow therethrough and pass over the top surface of the combustion chamber to keep it cooler than otherwise possible with heated room air.    Connective currents in another air duct formed between the shell and the combustion chamber circulates room air around the combustion chamber to transfer heat to the room air. The warmed outside air and room air mixes in a plenum above the fireplace prior to entering the room, thereby modulating the temperature of the heated air and permitting it to burn without excessively heating the room. A damper regulates the flow of outside air into the air vent, as desired.

Abstract: The invention relates to a connection for connecting a measuring device (6) to a gas pipe, comprising: a connecting element (1) for arranging in the gas pipe which divides the gas pipe into a first and a second piece (2, 3); a connecting plug (4) which can be coupled to the connecting element and which is connected to the measuring device by means of a measuring line (5), wherein the connecting element comprises a valve which is actuable by the connecting plug and which normally mutually connects the first and the second piece of the gas pipe and which, when the connecting plug is coupled to the connecting element, connects the first piece of the gas pipe to the measuring line and closes the second piece of the gas pipe. As a result of these measures the valve is operated by the connecting plug, so that opening and closing of taps is no longer necessary. The operation of such a connection is therefor greatly simplified. A perhaps even more important advantage lies in the fact that safety is ensured, since when the connecting plug is removed the measuring line is automatically closed.
