Abstract: A telecommunication device for the deaf (12, 14, 16, 20, 22, 24, 26, 28) operates under conventional Baudot communication protocol, but has enhanced features enabling it to handle interrupts either from a conventional or a similar TDD. The improved TDD is also capable of pseudo-duplex communication with a similar TDD in which each device transmits packets of characters alternatively to the other thus making it appear to the users that simultaneous transmission is occuring. The implementation of these features is done in such a way that the TDD is fully capable of communication with existing TDD devices and the device obeys normal rules and conventions for Baudot communication.

Patent CA-2118148-C (CA)
Inventor: APPEL WILLIAM DALE
IPC: H04L25/02
Filed: 1994-10-14
Granted: 1998-06-16
Abstract: Packaged signal routing circuits (e.g. on printed circuit cards or boards), route pulse signals with very short rise times from a lossy driver to multiple devices. In these routing circuits, a complex network of conductors branches from a common junction adjacent the driver output into multiple (in the disclosed embodiment, three) conduction paths of unequal length. In accordance with the invention, the internal impedance of the driver is matched to the aggregate charateristic impedance of the branch paths,  and a lossless compensating circuit is attached to a shortest branch path. The compensating circuit is designed to transfer signal reflections of predetermined form to the branching junction at the driver via the shortest branch. Without the compensating circuit, reflections presented to the branching junction from the shortest branch are dissimilar to reflections presented to that junction from other branch paths. Consequently, re-reflections return from the junction to the branches, causing distortions in signals sensed at the devices. However, with the compensating circuit connected in the shortest branch, reflections presented from that branch to the junction appear in a form matching  reflections  presented  by  the  other  branches;  and  the reflections from all branches then cancel  at the driver junction. Consequently, signals sensed at the devices have considerably reduced distortions due  to  the  absence  of  re-reflections.  In a preferred embodiment, the compensating circuit consists of a printed circuit trace of predetermined length (representing a transmission line stub with predetermined phase delay characteristics) in  series with a point capacitor (or several point capacitors) having predetermined capacitance (determining  the  shape  of  the  compensating  reflections).  The compensating circuit,  which extends beyond the end of the shortest branch, connects between the end of that branch and reference potential (e.g. ground). The end of the shortest branch is also attached to a device required to sense signals appearing at that point. A new method and polarized bridge device are disclosed for use in analyzing such networks in particular (and for analyzing transmission line effects in general).  This  method  and  device  permit  precise  observation  and comparison of reflections produced in branches of a network emanating from a common junction,  and accurate determination of compensation suitable for modifying such reflections.

Title: High-efficiency, self-supporting filter element made from fibers
Inventor: JEFFERY ANDREW B
IPC: B01D39/08
Filed: 1994-10-17
Granted: 2000-02-22
Abstract: A self-supporting filter element is produced from a precursor fiber web according to one of several methods. The precursor fiber web contains heat-shrinkable fibers or binder fibers or both. The web is exposed to temperatures sufficiently elevated to cause shrinkage of the fibers or melting of the binder. After cooling the web, the filter elements produced are self-supporting, and may have densities up to 500 kg/m3 to improve filtration while retaining good functional characteristics for operating pressure drop and air permeability. The self-supporting filter elements can be constructed of one material, and thus may be suitable for recycling.
