    Abstract: Disclosed are copolymers derived from ethylene and at least two different alkyl acrylate comonomers, with or without an acid cure site-containing comonomer. The copolymers can be derived from (a) from 10 to 50 weight % of ethylene; (b) 20 to 30 weight % of a first alkyl acrylate having from 1 to 4 carbons in the alkyl group; from 35 to 45 weight % of a second different alkyl acrylate having from 1 to 4 carbons in the alkyl group; and (d) from 0 to 5 weight % of a 1,4-butene-dioic acid moiety, or anhydride or monoalkyl ester thereof; the remainder being ethylene: wherein the copolymer has a number average molecular weight (Mn) above 40,000. Also disclosed are compounded compositions comprising these copolymers and cured compositions (i.e., vulcanizates) as well as rubber articles formed from these compounded compositions, such as constant velocity joint boots and shaft boots, hoses, dampers, seals and gaskets. These copolymers provide improved dynamic fatigue resistance of cured compounds while maintaining an expanded operating temperature range and oil resistance. Blends of other polymers with these copolymers are also disclosed.

    Abstract: Steerable electrophysiology catheters for use in mapping and/or ablation of accessory pathways in myocardial tissue of the heart wall and methods of use thereof are disclosed. The catheter comprises a catheter body and handle, the catheter body having a proximal section and a distal section and manipulators that enable the deflection of a distal segment of the distal tip section with respect to the independently formed curvature of a proximal segment of the distal tip section through a bending or knuckle motion of an intermediate segment between the proximal and distal segments. A wide angular range of deflection within a very small curve or bend radius in the intermediate segment is obtained. At least one distal tip electrode is preferably confined to the distal segment which can have a straight axis extending distally from the intermediate segment. The curvature of the proximal segment and the bending angle of the intermediate segment are independently selectable. The axial alignment of the distal segment with respect to the nominal axis of the proximal shaft section of the catheter body can be varied between substantially axially aligned (0° curvature) in an abrupt knuckle bend through a range of about −90° to about +180° within a bending radius of between about 2.0 mm and 7.0 mm and preferably less than 5.0 mm. The proximal segment curve can be independently formed in a range of about −180° through about +270° with respect to the axis of the proximal shaft section to provide an optimum angular orientation of the distal electrode(s). The distal segment can comprise a highly flexible elongated distal segment body and electrode(s) that conform with the shape and curvature of the heart wall.

    Abstract: A method is provided for transmission of packets (102) as a sequence of data packets (104). A redundancy or check word (106) is composed for each packet of the sequence of data packets. A transmission packet is composed of a packet, a check word of a prior packet in the sequence of packets, and a check word of a subsequent packet in the sequence of packets. The transmission packets are transmitted in a sequence and received in a sequence. After reception, the transmission packets are separated so that the packets are compared with the corresponding check words transmitted with adjacent packets in the sequence.

    Abstract: This invention relates to arrangements for eliminating loop-around trunks for operational calls. Such trunks are used when a single switch performs two distinct functions, such as local service and operator assistant service. In order to simplify software, the software for each of these functions is designed separately; in the prior art, if both functions are needed, two separate connections are established and are joined by the use of a loop-around trunk. In accordance with Applicant's invention, the loop-around trunk is eliminated by initially establishing a connection from a real time-slot to a virtual time-slot for the first function and from a virtual time-slot to a real time-slot for the second function; the real time-slots for receiving the call and for transmitting the call to an inter-office trunk are then connected in the switch without requiring the use of a separate loop-around trunk.

    Abstract: The tomato Cf-2 gene has been cloned and its sequence provided, along with the encoded amino acid sequence. DNA encoding the polypeptide, and alleles, mutants and derivatives thereof, may be introduced into plant cells and the encoded polypeptide expressed, conferring pathogen resistance on plants comprising such cells and descendants thereof. The Cf-2 sequence comprises leucine rich repeats and the presence of such repeats enables identification of other plant pathogen resistance genes. Homologies to Cf-9 reveal motifs useful in the identification of other plant pathogen resistance genes.

    Abstract: A system is disclosed that provides a goal based learning system utilizing a rule based expert training system to provide a cognitive educational experience. The system provides the user with a simulated environment that presents a business opportunity to understand and solve optimally. Mistakes are noted and remedial educational material presented dynamically to build the necessary skills that a user requires for success in the business endeavor. The system utilizes an artificial intelligence engine driving individualized and dynamic feedback with synchronized video and graphics used to simulate real-world environment and interactions. Multiple "correct" answers are integrated into the learning system to allow individualized learning experiences in which navigation through the system is at a pace controlled by the learner. A robust business model provides support for realistic activities and allows one or more users to experience real world consequences for their actions in one or more simulated environments and make decisions that entail realtime decision-making and synthesis of the educational material.
