Abstract: Methods and apparatus are provided for handling asynchronous transfer mode (ATM) cells sent from first user equipment through a plurality of ATM nodes and destined for second equipment, when the second equipment does not support ATM operations and maintenance (OAM) functionality.  In particular, an ATM node connected to the second equipment is configured as an OAM proxy connection end-point for the second equipment such that ATM data cells which are destined for the second equipment are sent in a usual fashion, but ATM OAM cells destined for the second equipment are terminated and acted upon by the ATM node and are not forwarded to the second equipment.  The proxy connection end-point functionality is preferably obtained by providing a user-friendly management information database (MIB) which stores configuration information for the ATM node.  The configuration information is used by a management processor of the node for deciding when an incoming OAM cell intended for the second equipment is to be terminated by the ATM node.

Inventor: HANNEMANN BIRGIT
IPC: G01N21/64
Filed: 1996-05-24
Abstract: The invention relates to a process for producing a sensitive single-layer system for the optical determination of a concentration of an analyte, e.g.  oxygen, in which the analyte can be examined in a liquid or gaseous aggregate state or in solution, by absorption, luminescence or luninescence washing of an indicator sensitive to the analyte which is preferably permanently immobilised in the optical beam path. The sensitive single-layer system is designed thereby to have a reproducible and very short response. To this end indicators are adsorbed on a filler, whereafter a mixture is made with a matrix material permeable to the analyte to be determined. The mixture is then applied under pressure to a substrate and the layer thickness is determined by the pressure applied. The sensitive layer applied is polymerised, polycondensed or cured and also homogenised by soaking in a fluorescence indicator solution.

Abstract: An automatic fish hook setting assembly includes a hook setting member that is interengaged with a fishing line following deployment of the fishing line      The hook setting member is held in a set position by a latching mechanism              against a biasing force tending to release the hook setting member  A weight transfer assembly is also engaged by the fishing line in a manner which causes the assembly to be shifted from a loaded position to an unloaded position when a force, exceeding a threshold amount, is exerted thereon through the fishing line by a fish tugging on the line      When unloaded, the weight transfer assembly abuts the latching mechanism           which causes the hook setting member      to be automatically released, thereby jerking the fishing line to snare the fish. The automatic fish hook setting assembly can be readily adjusted for use with various fishing styles and species of fish. In addition, a visual and/or audible indicator unit is provided in order to signal an unattending fisherman when a fish has been snared.

Title: An adaptive dual filter echo cancellation method
Inventor: KARLSEN JOHNNY
IPC: H03H21/00
Filed: 1996-10-16
Abstract: In a dual filter echo cancellation method a new quality measure (q a, q p) provides the basis for a new filter selection and transfer method.  The quality measure represents the performance of a filter in the adaptive echo canceller. According to the method, a correlation measure between an echo containing signal and an echo estimation signal produced by said filter is estimated. A power measure of a residual signal, formed by the difference between said echo estimation signal and said echo containing signal, is estimated. The quality measure is calculated by dividing said estimated correlation measure by said estimated power measure. An adaptive and programmable filter is used in the echo cancellation and the quality measures for them both are calculated and compared. The best of the two filters, as determined by the quality measure, is used for modelling the echo path (570, 580) and its filter coefficients are copied to the other filter.
