Abstract: The present disclosure relates to a method for synchronizing time alignment in a multi-channel radio frequency receiving system, the method including injecting an amplitude modulated reference signal into each channel in the multi-channel receiver at a location associated with each antenna input. Further, the method includes the steps of detecting a position of the reference signal within a time sample window and determining propagation time difference between each channel within the receiver electronics. Further, the method includes the steps of determining adjustment parameters, for synchronizing time alignment, for each channel and adjusting the channels in the time domain in accordance with the determined adjustment parameters of synchronization for each channel.

Abstract: A device, such as an electroactive device, may include primary electrode and a secondary electrode overlapping at least a portion of the primary electrode. An electroactive polymer element may include a composite polymer material and is disposed between and abuts each of the primary electrode and the secondary electrode. A phase change or other deformable medium such as a liquid, a gas, or a liquid-gas mixture may be disposed as inclusions within the polymer material. The device can be actuated by the application of a voltage between the electrodes and the attendant formation of a Maxwell stress, exposing the deformable medium to a source of radiation, changing a pressure of the deformable medium, or changing a temperature of the deformable medium, e.g., about a phase transformation temperature of the phase change medium.

Abstract: In some embodiments, an electroactive device includes a first electrode, a second electrode, and an electroactive element disposed between the first electrode and the second electrode. The electroactive element may include a plurality of voids distributed within the electroactive element. The electroactive device may have a non-uniform electroactive response based at least in part on a non-uniform distribution of voids within the electroactive element. The non-uniform electroactive response may include a non-uniform sensor response or a non-uniform actuation response. Various other methods, systems, apparatuses, and materials are also disclosed.

Abstract: The present invention relates to an aqueous quick-setting bitumen-aggregate mix suitable for cold pavement of roads, parking places, sidewalks and the like. The bitumen-aggregate mix is manufactured by mixing a mineral aggregate, water, a de-emulsifier, containing hydraulic cement, and a cationic oil-in-water bitumen emulsion, containing, as an emulsifier, a salt of a tertiary diamine and a phosphoric acid. The diamine has the formula (I), where one or two of the groups R1, R2, R4 and R5 designate a hydrocarbon group of 6–22, preferably 8–20 carbon atoms, and the remaining R1, R2, R4 and R5 groups are an alkyl group with 1–4 carbon atoms, and/or a group —(A)2H, where A is an alkyleneoxy group with 2–3 carbon atoms, and s is a number from 1–4, R3 is an alkylene group with 2–4 carbon atoms and n is a number from 0–2.

Abstract: The nozzle contains a conduit for supply of paste fuel. A tapering end of the conduit is located towards an outlet for the nozzle. A spout for supplying splitting air is directed towards the outlet for the nozzle. The jet of splitting air is imparted by the spout in the shape of a cone which has an outer edge tangent to an inner edge of the outlet for the nozzle.
