Abstract: The present invention regards a three-step process for the synthesis of 5-(alpha-hydroxyalkyl) benzo[1,3]dioxols. The process comprises: (i) the reaction of pyrocatechin (1,2-dihydroxybenzene) with a dihalo or di-alkoxyalkane, with the formation of a benzo[1,3]dioxol derivative; (ii) 5-selective catalytic acylation of the benzo[1,3]dioxol, with formation of a 5-alkanoylbenzo[1,3]dioxol and its subsequent (iii) reduction to 5-(alpha-hydroxyalkyl) benzo[1,3]dioxol. Also described are new benzodioxols obtainable using the above-mentioned process. The process of the invention is industrially simple and has low environmental impact; it allows to obtain in high yields derivatives of considerable interest, in particular for the perfumery industry, and in the sector of insecticides.

Abstract: A combat pilot system for an aircraft comprises corresponding combat pilot devices 12, 12' provided in a runtime module 14 on board the aircraft and a ground-based system training module 16 respectively. The run-time module 12' is trained using model data generated simulation model 18 as well as feedback data from actual missile firings. The matrix of weights derived from the training routines are then programmed into the neural network in the corresponding combat pilot aid system 12 on board the aircraft so that the runtime module is capable of processing the input data producing the four parameters required for launch of a missile and also a FIRE/NO FIRE indication to the pilot.

Abstract: A telecommunications service node is connected to a data network using a packet data protocol and a telephone network using a circuit switched protocol. The service node is also connected to a wireless roaming network using the IS-41 signaling protocol. The service node stores status information, including location and registration information, for mobile computing devices connected to the data packet network. The location information includes a temporary data network address for visiting mobile computing devices. The service node manages voice calls to and from the mobile computing devices. If a call is received to a mobile computing device which is not registered, the service node will attempt to connect the call to a wireless telephone associated with the mobile computing device, or a predefined destination established as a preference by the user. In the case of a voice call between a telephone connected to the telephone network and a mobile computing device connected to the data network, the service node acts as a gateway and translates between the data packet protocol and the circuit switched protocol. A personal information manager executing in a mobile computing device may be used for managing call processing functions of the mobile computing device.
