A plug mounted on an optical cable with one or more optical contacts each one having a tab which is deformable elastically or mounted so as to pivot relative to the rest of the contact, including: a body including a front part and a rear part; a bushing fitted around the front part with axial sliding forward, the bushing bearing a tab with an appendage extending inside the rear part, the tab of the bushing and the tab of each contact being disposed relative to each other so that when a traction force is applied to make the bushing slide around the front part, the appendage is able to bear against the tab of each contact so as to deform it elastically or make it pivot until the disconnection is produced between the contact and the converter.

A ladder landing support apparatus includes an angled base plate including a first portion and a second portion defining an angle with the first portion, and a ladder engaging part extending upwardly from a top side of the first portion, the ladder engaging part being engageable with feet of a ladder so as to substantially prevent slippage thereof in a direction parallel to the first portion, wherein the angled base plate is angled to engage a ledge such that the first portion is engageable with a top horizontal surface of the ledge and the second portion is engageable with a front vertical surface of the ledge.

The invention provides a transmitter comprising two (or more) phase locked loops controlling respective oscillators, and implementing different phase modulation. Multiple phases are derived from the respective oscillators, and an edge rotator forms an output signal from a combination of the phases. The oscillators can operate at different frequencies, neither of which is an integer multiple of the other, whereas the output signals of the multiplexers of the first and second phase locked loops are closer in frequency and can be the same. This reduces the problem of pulling, with a circuit that can be implemented with low power and area and with the versatility of being digitally intensive.

The invention belongs to the technical field of auto glass compressive strength detection, and discloses a compressive strength detection device, system and method for auto glass detection. The compressive strength detection system for auto glass detection includes: a detection sample processing module, a data acquisition module, data preprocessing module, central control module, compressive strength detection module, strength measurement curve establishment module, curve fitting module, evaluation module, data storage module, update display module. The present invention adopts the combination rebound of medium-sized hammer and high-strength hammer to detect the compressive strength of automobile glass, and improves the detection accuracy of the compressive strength of automobile glass; by establishing the strength of automobile glass with strength grades of C20-C45 and C50-C100 respectively Curves, expanding the scope of use of the rebound hammer, reducing the intersection between specifications and instrument use restrictions, making the strength estimation of automobile glass more convenient and fast; it is effective and feasible to fit the established strength measurement curve through the curve fitting module.

The invention provides a novel PVC (Polyvinyl Chloride) pipe manufacturing unit, belonging to the field of PVC pipe manufacturing equipment. The novel PVC pipe manufacturing unit comprises a pipe discharge device, wherein the pipe discharge device comprises at least two hanging racks, a conveying device and a plurality of hanging brackets; the upper end of each hanging rack is slidably connected onto a first cable rail; each first cable rail is connected with a first lifting device; the conveying device is provided with a conveying guide rail and a conveying mechanism; the hanging racks and the hanging brackets are separately arranged on positions close to two ends of the conveying guide rail; the upper end of each hanging bracket is slidably connected onto a second cable rail; the second cable rail is connected with a second lifting device; and the upper end of each hanging bracket is provided with a control mechanism. By adopting the novel PVC pipe manufacturing unit, an extrusion-moulded PVC pipe can be drawn, conveyed and placed; a longer PVC pipe can be drawn in a section-wise cyclic manner; the PVC pipe is prevented from being drawn in an integral manner, so that the traction is more labor-saving; the PVC pipe is prevented from being bent during placement; and the automation degree is high, and the pipe discharge efficiency is greatly improved.

The invention discloses a vehicle backward sliding protection method. The method comprises the steps that the average value of the speeds of multiple motors is calculated; whether the vehicle slides backwards or not according to the mean value is judged; if the vehicle slides backwards, the backward sliding stage of the vehicle is determined according to the mean value; and according to the backward sliding stage of the vehicle, a protection measure corresponding to the backward sliding stage is executed. By applying the method, the vehicle can be prevented from shaking, and the availability of the vehicle can be guaranteed while the safety of the vehicle is considered. The invention further discloses a vehicle backward sliding protection apparatus and device and a computer readable storage medium which all have the technical effects.
