Title: Composite polymer devices for controlled release of semiochemicals
Inventor: WAKARCHUK DAVID A
IPC: A01N25/18
Filed: 1997-10-10
Abstract: Composite  polymer dispensers  capable  of controlled release of semiochemicals have been developed.  The dispensers make use of a solid elastomer matrix reservoir which is at  least partially surrounded by a permeable release rate controlling polymer membrane.   The matrix materials are polyurethanes compatible with many types of semiochemicals and additives.  The release rates of semiochemicals from the dispensers can be varied over a wide range by manipulation of the reservoir conditions and by selection of the type of permeable polymer membrane surrounding the device.  The dispensers can have a variety of forms and can be produced by a simple process.  The semiochemical devices produced by this method are useful for managing  insect  and other pests  through attraction to traps, for population monitoring or for mass trapping.  The devices may also be used to dispense  anti-aggregation pheromones or repellents in addition to use for mating confusion or disruption.

Title: Active demarcation point of an access network
Inventor: HEIDEMANN ROLF
IPC: H04N7/173
Filed: 1997-11-04
Abstract: In a hybrid fiber/coax access network (NET) with downstream and upstream channels, the upstream channel serves to transmit voice and video signals as well as data signals from groups of customer locations (END) to a subcenter ( HUB). A demarcation point (UP) provides the interface between the access network (NET) and the private network of the customer location (END). It contains at least two devices (BP4,BP5, BP6) for frequency-splitting received signals in the upstream frequency band, at least two switches (S4, S5,S6) following the at least two devices (BP4,BP5, BP6) and serving to block or unblock individual upstream frequency ranges, a measuring unit (MESS2) for measuring the amplitudes or intensities of the signals in the split frequency ranges, and a control unit (CTRL) for evaluating the measured values and controlling the at least two switches (S4,S5,S6). For a customer location (END), individual upstream frequency ranges can thus be telemetrically blocked for a limited time. Decentralized and autonomous monitoring of individual upstream frequency ranges is accomplished by a measuring unit which is controlled by the demarcation point (UP) itself.      (Fig. 2)
Patent CA-2219708-A1 (CA)
Title: Synthesis of macrocyclic polymers with group iia and iib metal cyclic organometallic initiators
Inventor: HALL JAMES E
IPC: C08F4/44
Filed: 1997-10-29
Abstract: The invention is a practical process for anionically synthesizing commercially significant quantities of macrocyclic polymers from polar and/or non-polar monomers by using Group IIA and IIB metal cyclic organometallic initiators. Activation of the ring metal atom results in anionic polymerization of the monomers by addition into the initiator ring at the bonds between the atom and its two adjacent carbon atoms, the metal atom acting as a bridge between the two living ends of the propagating chain. Coupling of the cyclic polymer living ends by coupling agents produces macrocyclic polymers that are stable in air and moisture and that exhibit desirable properties, such as low viscosities at high molecular weights. Such macrocyclic polymers provide enhanced polymer processability during molding, extruding and the forming of films. Macrocyclic polymers terminated with coupling agents that also provide functional groups may be compounded to produce vulcanizable elastomeric compounds and articles that exhibit reduced hysteresis properties.

Title: Segmented sliding yardsticks error tolerant fingerprint enrollment and verification system and method
Inventor: DRAGANOFF GEORGI HRISTOFF
IPC: G06K9/00
Filed: 1998-04-22
Abstract: A fast position tolerant and economical fingerprint verification algorithm and software implementation is disclosed. The algorithm has very important advantages in comparison to existing fingerprint verification algorithms like minutia extraction or full image analysis based on series of two dimensional fast Fourier transforms (FFT's) and two dimensional cross correlation in speed, compactness of the template and finger positioning for verification. It is based on a small "yardstick" pattern being moved inside the image to be verified, and when a match is found the rest of the verification process is started. The yardstick is divided into segments in order to fit different DSP  and microcontroller register lengths and structures. The software code implements the algorithm in the most efficient way for utilization on a digital signal processor architecture. A main area of application is in fingerprint identification and verification, but it could be implemented with same success in other image verification systems like iris, eye, face etc., where two images should be compared. The algorithm is adaptive, so various false acceptance and false rejection coefficients could be utilized very easily. It also produces a very compact template, which leads to better memory utilization in fingerprint databases.
