Abstract: A compact optical time domain reflectometer (OTDR) containing a small-scale OTDR, power source, and wireless communications electronics encompassed within the confines of a spool containing a time delay fiber optic waveguide coiled about the face of the spool. Data obtained by the OTDR is transmitted by wire or wirelessly to a computer or portable wireless device for graphical plotting of said data and evaluation by the user. The integration of the time delay waveguide eliminates the need for a separate time delay waveguide and provides a more compact testing solution. The Compact OTDR with Integrated Time Delay is used to test the integrity of an optical fiber waveguide.

Abstract: The present disclosure relates to methods, devices or streams for encoding, transmitting and decoding two-dimension point clouds. When encoding point clouds as frames, a large number of pixels are not used. A dense mapping operator optimizes the use of pixels but requires a lot of data to be encoded in the stream and its inverse operator is difficult to compute. A simplified mapping operator is generated according to a dense mapping operator and is stored as matrices of two-dimension coordinates representative of an unfolded grid which requires low space in the stream. The inverse operator is easy to generate according to the unfolded grid.

Abstract: A fast convolution method applicable to convolving a signal (indicative of an n-dimensional pattern, where n is greater than or equal to two) with a smooth kernel that can be approximated by a separated-spline kernel, and a system configured to perform such method using software or signal processing circuitry. Unlike Fourier-based convolution methods which require on the order of N log N arithmetic operations for a signal of length N, the method of the invention requires only on the order of N arithmetic operations to do so. Unlike wavelet-based convolution approximations (which typically also require more arithmetic operations than are required in accordance with the invention to convolve the same signal), the method of the invention is exact for convolution kernels which are spline kernels.

Abstract: A winding machine for winding wire includes a spindle on which a spool is mounted, and a reciprocating traverse for guiding an advancing wire onto the spool. The motion of the traverse is controlled by a programmable motion controller. A cam profile is stored in the controller's memory which defines the relationship between the traverse position and the angular position of the spindle. A periodic rotation signal is generated indicative of the angular position of the spindle. In response to each periodic rotation signal, the programmable controller determines the corresponding position of the traverse as set forth in the cam profile and produces a control signal which causes the traverse to move to the commanded position. Gear ratios between the spindle motor and traverse motor are supported.

Abstract: In winding coils of great wall thickness, such coils including a plurality of layers each formed of a plurality of figure-8s with the cross-overs progressing angularly around in each layer and with a radial hole extending from the outside of the coil into the axial opening thereof, by previous winding methods it is likely that the hole will be curved, even in cases where the guide for traversing the flexible material on the mandrel is spaced away from the mandrel and the outside of the wound material. In order to prevent the formation of a curved hole and to ensure that the hole is substantially radial, the guide carrier is moved in such a way that the line from the carrier to the surface of the coil always remains substantially tangential to the package at the same angular position in space with respect to the mandrel.

Abstract: In a coil of material wound in a series of figure-8 coils with the crossovers progressing around the package but being interrupted at one point to provide a radial opening into the axial opening of the coil, in order to produce a thick-walled coil the material is first wound in a normal way with varying gains in order to produce a set of dense inner layers, while the outer layers are wound without variation in the gain to produce a honeycomb structure. The honeycomb section is of greater width (axially of the package) than the inner layers. A plurality of pins slidably mounted on a strip are pushed into the outside of the package through the openings in the honeycomb, whereafter the outer layers are compressed axially while retaining the pins within the outer layers. The pins permit payoff of the outer layers without danger of their collapsing and thereby forming kinks or twists within the package.

This hole is ordinarily somewhat diamond shaped, with its major axis extending substantially perpendicular to the axis about which the material was wound. A payout tube is placed in that hole, this payout tube having an oval shape.

Abstract: For guiding flexible material wound in a figure-8 package with inner end feedout, a coil is enclosed in a container with walls of corrugated cardboard. The payout of the material is guided by a tube having a flange adjacent the outer end, and two outwardly extending projections between the flange and the outer end, leaving a space therebetween. The inner edges of the projections are slanted in opposite directions. The tube is inserted into a coil, which is then inserted into a container formed of corrugated material. The corrugated material has an opening equal in diameter to the diameter of the tube and notches on either side of such opening extending in the direction of the corrugations. The outer end of the tube is brought through this opening, with the projections extending through the notches, and is then turned by 90.degree.. The thickness of the cardboard is slightly less than the space between the projections and the flange.

The tube is inserted from the outside into the radial opening of the coil, which is then placed inside the container with the outer end of the tube directed towards an opening in the container, which has notches therein. Upon turning the tube, the outwardly bent portions ride up on the wall of the container, so that the tube can be turned to a position in which the principal part of the outer flange engages against the outside of the wall.

The funnel guides the loops falling off of the inside wall of the package so as to prevent birdsnesting and provide for continuous and rapid payout.
