Title: Communication network with incoming calls directed through moving cells and method for operating same
Inventor: REDDEN JAMES P
IPC: H04B7/185
Filed: 1995-03-02
Abstract: A network includes a system and a population of subscriber units. System satellites move in low earth orbits and form moving cells on the surface of the earth. A pattern of static areas that covers the service area of the system is defined in a map. The system discovers the static areas for the subscriber units. When an incoming call needs to be directed to a subscriber unit, the subscriber unit's static area is converted into identities of beams that form the cells that coincide with the static area. A ring signal is transmitted in only these cells. Subscriber units monitor area identification signals that identify the static areas coincident with the cells where the signals are transmitted. When the static area known by the system is not among the identified static areas, a subscriber unit engages in re-registration communications.

Title: Method of measuring the nonlinear refractive index in a single-mode optical fibre
Inventor: ARTIGLIA MASSIMO
IPC: G01M11/00
Filed: 1995-05-29
Abstract: To measure the nonlinear refractive index of an optical fibre, each pulse emitted by a source (L) is split into a pair of pulses which are sent in opposite directions into an optical-fibre Sagnac interferometric loop (AS) which includes the fibre under test (F). One of the pulses of the pair is attenuated before passing through the fibre (F) in such a way that only the other one has such a power as to induce nonlinear effects in the fibre (F). The interference between parts of pulses is analysed at the output of the loop (AS) and the nonlinear refractive index is derived from a measurement of the phase shift between the two pulses of the pair.

Alignment holes are formed through the housing and the cam assemblies to facilitate proper alignment of the cam assemblies relative to one another during assembly of the dispenser.  The cam assemblies move inward and outward relative to the opening to accommodate cups of different under-rim diameters within a given range.  In particular, the cam assemblies move in an arc and pivot relative to the housing and thereby remain satisfactorily aligned relative to the center of the opening over a wider range of under-rim cup diameters.
Patent CA-2153033-A1 (CA)
Title: Intelligent based selective call forwarding
Inventor: CARLSEN RALPH
IPC: H04M3/54
Filed: 1995-06-29
Abstract: A telephone subscriber who wishes to forward calls placed to that subscriber from a selected set of calling parties identifies the current destination number to a service adjunct. The service adjunct, in turn, transmits the destination number to the intelligent terminals of preselected parties while those intelligent terminals are in an inactive (i.e. on-hook) mode, for storage in a local memory contained in those terminals. Thereafter, when the usual number of the telephone subscriber is "dialed" (e.g., entered on the keypad) at any one of the intelligent terminals, the stored destination number is retrieved and output to the telecommunications network in place of the usual number. The actual destination number is also displayed to the calling party who then has the option to let the call complete or disconnect to stop the call.

Title: Device for optical measurement of width/thickness
Inventor: RYDNINGEN TONI
IPC: G01B11/04
Filed: 1994-04-15
Abstract: A method for automatical, contactless and optical video measur-ing of the dimension of one or more objects being at rest or being conveyed parallel along a straight path. The measuring system as il-lustrated in figure 2 is based on the fact that a CCD video camera (5) through two parabola-shaped mirrors (3, 4), in the course of 6 to 12 lines, senses a section of the objects (7) to be measured, perpendicular to the direction of motion thereof. The parabola-shaped mirrors con-tribute to avoid erroneous measurements which, otherwise, would have arisen due to camera optics and the varying distance to the objects to be measured. The object to be measured is illuminated obliquely by means of two elongated light sources (1, 2). Camera and mirrors are mounted in a dust-tight cabinet, allowing the contrast information of the object to be measured to pass only through an elongated aperture (8), covered by a glass adpated to shut out light of unfavorable wave length. By means of electronics, the video informations are converted into TTL levels and digitized. Binary number representations for the dimension values are laid out to a communication gate, such that they can be fetched by a computer. The measurement takes place individu-ally for each single object to be measured. Used as a kerf controller at saw or timber mill, the operator will be informed of the actual values, and an alarm could be given if the actual values differ more from the reference values set than a predetermined limiting value.
