    Abstract: A system and method for receiving direct sequence spread spectrum transmissions with both chip code and frequency uncertainty including a parallel frequency acquisition technique for increasing receiver sensitivity and increasing process gain while reducing a preamble duration required for spread spectrum acquisition. The system and method include techniques for reducing effects of jamming and impulse noise on receiver performance via enhanced antenna diversity by constructively combining received signals. Further, techniques are provided which compensate for chip code alignment drift, providing an associated transmitter maintains carrier and chip code coherence, by comparing received signal energies at varying chip code alignments. These techniques enable the use of lower cost frequency setting crystals in both the receiver and transmitter as well as provide for system operation over a wider temperature range.

    Abstract: A wireless alarm system using spread spectrum transmitters, fast frequency shift keying, spread spectrum receivers and computer with a display. The spread spectrum transmitter includes an oscillator coupled to a microprocessor with chip code generation means, preamble register, address register and data register. The spread spectrum receiver acquires synchronization of the spread spectrum signal using a microprocessor coupled to the quieting, signal strength or baseband output of the receiver, with a two step algorithm. The steps comprise achieving a coarse lock and a fine lock to the spread spectrum signal.

    Abstract: A propeller includes a rotatable hub with a plurality of sockets, blades with roots that fit in the sockets and a plurality of pitch blocks which fit between the blade root and the socket walls. Hubs with two, three, and four sockets are shown. The blades have no twist and are formed of molded, glass reinforced nylon. The pitch blocks are also nylon and different pairs of pitch blocks may be used to hold the blades at different angles. All nylon components are designed to minimize stress concentrations. The hubs although also of nylon have steel reinforcing plates within them which take the centripetal forces. These forces are transmitted through bolts to passage walls in the pitch blocks, and from the pitch blocks through interengaging teeth to the blade roots. A snap on, snap off aerodynamic spinner is also provided.

    Abstract: A modeling tool for determining the impact that a data warehouse solution will have upon a business organization considering implementing a data warehouse solution. The modeling tool is implemented on a server computer with restricted access through a client computer. A server computer includes: a business impact model comprising a mathematical representation of a data warehouse solution, and an assessment questionnaire; and a modeling application for calculating a value of a data warehouse solution to a business organization from the business impact model and assessment questionnaire answers. A client computer is connectable to the server computer for receiving a copy of the business impact model, and providing offline collection of answers to the assessment questions, and offline calculation of a value of the data warehouse solution to the business organization. An application residing on the server computer keeps a record of the business impact model received by the client computer.
