Electrical components may have plastic packages. Contacts may be formed on exterior surfaces of the plastic packages. A plastic package for an electrical component may have an elongated shape that extends along a longitudinal axis. A first groove may run parallel to the longitudinal axis on a lower surface of the plastic package. A second groove may run perpendicular to the first groove on an opposing upper surface of the plastic package. The electrical components may be coupled to fibers in a fabric such as a woven fabric. A first solder connection may be formed between the first groove and a first fiber such as a weft fiber. A second solder connection may be formed between the second groove and a second fiber such as a warp fiber.

A loom monitoring system includes loom computers and a host computer connected to the loom computers through a network. Each loom computer acquires a temporary IP address from a DHCP server when a fixed IP address is not set for the loom computer and requests the host computer to transmit a fixed IP address using the temporary IP address. The host computer assigns a fixed IP address to the loom computer that transmitted the assignment request signal and correlates the fixed IP address with a loom layout map. The loom computers each transmit an acquisition completion signal to the host computer using the fixed IP address in a designated order based on the loom layout map. The host computer correlates the fixed IP address of each loom computer with the loom layout map in accordance with the designated order.

Systems and methods for on-loom detection of faults in fabric. An image-capture trigger-mechanism triggers an imaging device to capture a first image of a section of the weaving area at a first instant during each weft insertion cycle and a second image of the section of weaving area may be captured at a second instant during each weft insertion cycle. The images may be timed to provide images of the warp yarns and the weft yarns at optimal instants during the weft insertion cycle. An image processor detects irregularities in the data received from the imaging device.

An on-loom fabric inspection system comprising at least one imaging device configured to collect images of at least one section of a weaving area of a loom including a shed region, a woven fabric region and a fell region. The system is operable to detect faults in the weaving area and to produce batches of woven fabric assigned with an objective quality index.

The invention relates to a system comprising: a harness for a weaving loom and a device for monitoring the manufacture of a preform woven by the loom, the monitoring device comprising: a plurality of sensors, each sensor of the plurality of sensors being connected to one of the plurality of strings and being configured to measure a deformation of the string, the deformation being induced by a force exerted by the loom on the string to which the sensor is connected; and a processing unit connected to the plurality of sensors and configured to analyse the deformation so as to identify a manufacturing abnormality on at least one string.
