A zipper-type circuit fabric and smart clothes composed thereof include a clothes body. The clothes body is made of waterproof conductive fabric body. The waterproof conductive fabric body includes a plurality of conductive wires and conductive contacts. Rectangular elongated conductive media and folded conductive media are arranged inside the conductive wires so that the conductive media are stable and ductile. The clothes body is further provided with a waterproof zipper body. The zipper teeth on the waterproof zipper body are all electrically connected to the conductive wires. When the zipper body is closed, a metal probe on a zipper tooth is placed into a connecting slot so that the left and right sides of the clothes body form a closed circuit. The clothes body can be connected to glove bodies and includes a plurality of flexible sensors internally.

Systems, methods, and structures that provide distributed acoustic sensing using chirped optical pulses of selectable duration and bandwidth, at a frame rate limited by a round-trip propagation time of a fiber under test. Instead of processing a transmitted chirped pulse as a single sequence—our systems, methods, and structures employ a parallel fragmented multiband architecture, where each tributary correlates the received signal with a truncated chirped pulse to obtain the Rayleigh impulse response over its frequency band. By reducing the duration of the chirp processed by each tributary, spatial leakage is reduced at all the tributaries, thus even after combining all the interferometric products from all tributaries using a rotated vector sum, the resultant signal is much less impacted by spatial leakage than by using a conventional TGD-OFDR method.

The invention addresses the problem of providing a cloth and a protective product, which are excellent not only in flame retardancy but also in protection performance against electric arcs, and can further be provided with any color appearance. As a means for resolution, in a cloth including a flame-retardant fiber, a UV absorber or carbon particles are contained in the cloth, and the cloth is configured to have a lightness index L-value of 25 or more.

To provide a flexible conductive base member and a multilayer conductive base member including the same, having no problem of failing to function as a contact and causing a variation in height between contacts.

There are a covered region 10 covered with a noble metal and a non-covered region 20 not circumferentially covered with a noble metal on a surface of a reticulated fibrous body 50. The covered region 10 is located at an intersection 7 of fibers 5 of the reticulated fibrous body 50, and the intersections 7 are connected to each other. The non-covered region 20 is located between the intersections 7 of the fibers 5 of the reticulated fibrous body 50.

For a woven fabric (20) with an additional thread (30, 34) laid out in a zigzag shape, in order to ensure in certain cases that the zigzag thread (30, 34) has its zigzag tip (38) always at the same position over the length of the woven fabric, it is proposed that the weft thread (24) is introduced at certain points in the woven fabric (20) in a floating manner over a plurality of adjacent warp threads (21) and that the feed needle (32, 36) is introduced or inserted into the woven fabric (20) at least at one side of the zigzag laid cover thread (30, 34) at several laying points or at all laying points where the weft thread (24) is floating over several adjacent warp threads (21). The cover thread (30, 34) is positioned at the inside of the zigzag shape.

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.
