The present invention provides a light-receiving circuit that protects the breakdown of the avalanche photodiode by the photo current. The tire chain tightener has an length of elastic material with a hook attached to each end. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. A second deck is connected to and transversely spaced apart from the first deck, such that at least lateral access to both the first and second support surfaces is provided.
