The anchor cable includes a steel strand (100), with an energy-absorbing and yielding terminal (200) and a stressed expansion-cracking terminal (300) respectively fixed to two ends of the steel strand, a bushing (400) sleeved outside the steel strand, a first lock (610) provided at one end of the steel strand and a second lock (620) provided at the other end of the steel strand; the stressed expansion-cracking terminal includes a self-anchored bushing (420) with a plurality of pre-splitting lines (440) arranged in the wall of the self-anchored bushing. Under stress, the wall of the self-anchored bushing cracks along the pre-splitting lines and bends and expands, so that it abuts against and is self-anchored to the edge of a sectional coal pillar at the outer side.

Abstract: A novel and useful digitally intensive event-driven quasi-level crossing (quasi-LC) delta modulator analog to digital converter (ADC) with adaptive resolution (AR) for Internet of Things (IoT) wireless networks. Minimizing the average sampling rate for sparse input signals significantly reduces the power consumed in data transmission, processing, and storage. The AR quasi-LC delta modulator quantizes the residue voltage signal with a 4-bit asynchronous successive approximation register (SAR) sub-ADC, which enables a straightforward implementation of LC and AR algorithms in the digital domain. The modulator achieves data compression by means of a globally signal dependent average sampling rate and achieves AR through a digital multilevel comparison window that overcomes the tradeoff between the dynamic range and the input bandwidth in conventional LC ADCs. Engaging the AR algorithm reduces the average sampling rate by a factor of three at the edge of the modulator's signal bandwidth.
