Abstract: The invention relates to the isolation and cloning of the structural gene, hipP, for the NTHi pili serotype 5 and the LKP operon. The invention relates to DNA molecules capable of hybridizing to the DNA sequences of the Haemophilus influenzae genome related to the pili. The invention further relates to a DNA molecule which encodes a pili protein, particularly a tip adhesin protein. The DNA molecules of the invention can be used in a method for assaying a sample, such as a blood sample, for the presence of Haemophilus influenzae in the sample. Accordingly, the invention further relates to the use of the DNA molecules as a diagnostic. The invention also relates to a recombinant Haemophilus influenzae pili protein, such as a tip adhesin protein. The protein can be employed in a method for immunizing an animal, such as a human, as a therapeutic or diagnostic.

Granted: 2001-12-18
Abstract: Limiting the base stations to which a wireless terminal will attempt to establish communication. In a first and second embodiment this is done by the wireless switching system or another system having the capability of storing within each individual wireless terminal a list of base stations that can be utilized by that wireless terminal. When a wireless terminal first registers on the wireless switching system, the wireless switching system would be responsive to the identification code of the wireless terminal to transmit a list of base stations that can be utilized by the wireless terminal to the wireless terminal. The wireless terminal then stores that list for future use. In a third embodiment, each tenant would be assigned a group number. Each of the base stations would periodically transmit the numbers of thegroups that could access the base station. A wireless terminal monitors these group numbers before attempting to register on a base station.

Abstract: This invention relates to radio communications and in particular relates to an adaptive antenna system for a radio communications system. In radio communications, signals are transmitted at a particular frequency or in a frequency band. The signals may be modulated in a variety of fashions using techniques such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and a multitude of other techniques. Nevertheless there are a finite number of available individual communications channels for separate sets of parties to communicate with each other. The present invention seeks to provide an improved form of adaptive signal transmission and reception without unduly increasing the signalling overhead of the system. According to one aspect of the invention there is provided a radio system operating over a channel having characteristics such that parameters of a transmission path can be predicted from received signals; said system comprising means for analysing signals received from said channel and a plurality of signal generation means adapted to vary output in response to said signal analysis.

Abstract: A monitoring apparatus includes sensors for interconnection with the load output terminal of a corresponding circuit breaker. The sensors sense the closed and open states of the corresponding circuit breakers and produce closure signals at outputs. The sensor outputs are interconnected in series to produce a combined closure signal for all of the circuit breakers. An indicating circuit interconnected with the combined closure signal outputs a signal, such as a relay contact or an audible, visual, or digital signal, to indicate the combined closure status of the circuit breakers.

Granted: 2001-08-07
Abstract: The secondary slot normally formed between adjacent shafts of a material separation screen is eliminated by mounting primary discs alternately with secondary discs. The primary and secondary discs each have the same shape but the secondary disc has a smaller outside perimeter. The primary and secondary discs preferentially have an arched pentagonal shape. The primary discs on one shaft are aligned with the secondary discs on an adjacent shaft. In other words, the large disc is positioned on a shaft to align with a smaller disc on an adjacent shaft. The oppositely aligned and alternating arrangement between the large discs and small discs reduce problems that exist in screens that use in-line multi-sided discs.

Abstract: A dispensing apparatus dispenses a precisely metered quantity of pellets or granular material from a hopper to a vessel. The hopper which holds the pellets or granular material has a conical bottom portion which terminates in a bottom opening that is in constant communication with a conveyor tube which leads to the vessel. The conveyor tube preferably extends horizontally below the hopper and is in communication with a bottom opening in the hopper. A venturi driven by compressed air is provided in the conveyor tube for creating a vacuum which carries the pellets or granular material from the hopper to the vessel. The pressure of the compressed air entering the venturi is precisely regulated so as to precisely control the amount of pellets or granulated material moved from the hopper to the vessel. Alternatively, a controller can be provided for regulating several conveyor tubes, each to feed a different type of pellet or granular material into the vessel.

Abstract: A system and method for analyzing coupon redemption data, the system having a parallel adaptive, self-arborizing network including a database component having a database containing consumer and client information, an extract module program that retrieves information from the database based on a set of user or computer designed criteria, an editor program which formats the information extracted from the database to be generated on a coupon or flyer to create a data template including at least one two dimensional bar code containing consumer and coupon information from the database and a printing tool for encoding the data template on a coupon page. The system further comprises a data recovery system, including at least one scanning device provided at the point of sale terminal adapted to read the two dimensional bar codes on the coupons and a store and forward system that stores the data collected by the scanning device at the point of sale terminal. The data redemption system includes a data accumulator that retrieves redeemed coupon information from the store and forward system in the retail client's store, which is transferred to a database analysis component of the parallel adaptive network via an Internet or similar modem communications transfer. The database analysis component of the parallel adaptive network analyzes the consumer and client information from the redeemed coupon data to determine consumer purchasing trends. The database analysis component learns from the analysis of consumer purchasing trends to define a modified set of coupon printing criteria based on the analysis.

Granted: 2002-03-26
Abstract: The alarm system has an alarm unit for ready access at a point of entryway which communicates with a line seize module located in a secure location. The alarm unit has a transmitter receiver, a control panel function, a key pad, and an input/output port for connection to telephone wiring for communicating with the line seize unit. The line seize module includes its own input/output communication port connected to the wiring of the local telephone line and as such, is in direct communication with the alarm unit.      Communication is separate and distinct from normal telephone communication and preferrably is at a high frequency above the audible range. This allows the alarm system to communicate between components while still allowing full conventional use of the telephone lines. The line seize module also includes control logic, a line seize arrangement and an automatic dialer. When an alarm condition occurs, the alarm unit transmits a signal to the line seize module which then takes appropriate steps to contact the remote monitoring station via the telephone system. This two part alarm system which communicates over the existing telephone wiring, reduces the vulnerability of the system to defeat.
