A drawer-sliding device. The device includes an outer sliding member fastened with a cabinet or the like. A middle sliding member is mounted slidably in the outer sliding member, and an inner sliding member is fastened with the drawer and mounted slidably in the middle sliding member. The inner sliding member is provided with a coupling element. The outer sliding member is provided with a fast return element and a spring element. When the inner sliding member and the drawer are drawn out, the coupling element of the inner sliding member is engaged with the fast return element so as to bring about an outward displacement of the fast return element, thereby resulting in deformation of the spring element. When the inner sliding member is pushed back into place along with the drawer, the fast return element and the coupling element are forced by the spring element to move back into place.

A gas cushion bag includes two layers, and the two layers are overlapped with each other and partially connected with each other to form a plurality of connecting portions and at least one gas storage unit. Each of the at least one gas storage unit is sealed circumferentially and includes at least one first segment and a plurality of second segments communicated with the at least one first segment. The at least one first segment and the plurality of second segments are alternatively arranged in a first direction. Wherein as viewed along the first direction, a cross-sectional profile of each of the at least one first segment is smaller than a cross-sectional profile of one of the plurality of second segments when the at least one gas storage unit is inflated.

A quasi-resonant inverter control system includes a mains zero-crossing detection circuit and a controller. The mains zero-crossing detection circuit is operable to detect a plurality of zero-crossing points of an input alternating-current voltage and output a zero-crossing detection signal based on the zero-crossing points. The controller is operable to control a plurality of burst mode period and receives the zero-crossing detection signal. Each of the burst mode periods includes a working duration and a non-working duration. Each of the working durations includes a start point and an end point. The controller is operable to determine the start points and the end points of the working durations based on the zero-crossing detection signal and outputs a control signal based on the start points and the end points of the working durations. An electric heating device and a method for controlling the quasi-resonant inverter are also disclosed herein.

A method for testing a digital to analog converter, which operates in an undersampling environment, wherein signals of a tested DAC and a signal generator are modulated by a PWM device and then processed by a digital processing circuit to generate a digital signal, whereby is formed a low-speed equivalent ADC. The signal generator is provided by uniform-distribution random test patterns, and the signal generator generates an uniform-distribution random analog signal to the equivalent ADC. Thereby, the test error caused by the non-ideality of the signal generator is corrected, and the tested circuit can work in a full speed.

A method for capturing and managing training data collected online includes: receiving a first dataset from one or more online sources; sampling the first dataset and generating a second dataset, the second dataset including the data sampled from the first dataset; receiving an annotated second dataset with predefined labels; and dividing the annotated second dataset into a training dataset and a test dataset. The disclosed method further includes: configuring a machine learning based classifier based on the training dataset; predicting at least one data point based on the training dataset and calculating a confidence score; comparing the at least one predicted data point to the test dataset; sorting the at least one predicted data point based on its confidence score; and receiving corrected training data associated with the at least one predicted data point.
摘要:
The present invention discloses a multi-level output signal converter, which is connected to an audio amplifier. The audio amplifier comprises a comparing/measuring device, an encoder and an output unit. The multi-level output signal converter comprises a timing processing unit and a multi-level converter. The timing processing unit is connected to the comparing/measuring device and the encoder. The timing processing unit includes a plurality of flip-flops and a timing summing element. The flip-flop receives a first signal from the comparing/measuring device and outputs the first signal to the timing summing element. The encoder converts the first signal into a second signal. The multi-level converter is connected to the encoder and the output unit. The encoder transmits the second signal to the multi-level converter, and the multi-level converter thus outputs a third signal to the output unit.

The sucker and the exhaust are arranged in an elevator for elevating the corrugated boards and respectively suck air and exhaust air simultaneously.
摘要:
A method of manufacturing a sticker type antenna, in which a copper foil of 0.017 mm by thickness is stuck to a layer of releasable film in advance, in order that the copper foil can bear the pulling force in a brush electroplating process to thereby substitute the conventional beryllium copper of a larger thickness. The copper foil after brush electroplating undergoes punching and cutting for forming a pattern and is stuck to a semi-finished product of Mylar, hence the copper foil is stuck onto the back side of the Mylar layer; then the Mylar layer with the copper foil is separated from the releasable film, then the back side of the Mylar layer is applied with adhesive and again is stuck to the releasable film; after punching and cutting the Mylar layer for patterning and edging, a sticker type antenna is made.
