The apparatus for foreign language study includes: a voice recognition device configured to recognize a speech entered by a user and convert the speech into a speech text; a speech intent recognition device configured to extract a user speech intent for the speech text using skill level information of the user and dialog context information; and a feedback processing device configured to extract a different expression depending on the user speech intent and a speech situation of the user. According to the present invention, the intent of a learner's speech may be determined even though the learner's skill is low, and customized expressions for various situations may be provided to the learner.

A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

A system for preventing overflow of a toilet includes a capacitance sensor arrangement as in combination with certain features (e.g., flap valve disablement). The system can detect an overflow flush condition of a toilet by sensing the value of a parameter of one or more normal flush cycles of the toilet and establishing a normal range for the value of the parameter using the sensed value. The system can also store the normal range in a memory for comparison to a value of the parameter during subsequent flush cycles. The system can perform sensing over a predetermined timeframe. The system can include the time frame being sufficient to include the entire push cycle of the toilet.

The application relates to the technical field of climbing tools, in particular to a portable foldable anti-swing climbing board, comprising a hook, a hanging rope, an anti-swing bracket and two pedals; the first ends of the two pedals are pivotally connected through a hinge; The two ends are respectively connected with the second ends of the two pedals; the hook is arranged in the middle of the suspending rope; the sides of the two pedals are provided with grooves matching the anti-swing brackets; the anti-swing brackets are retracted in the pedals through the grooves; The anti-swing bracket is rotatably connected with the pedal. In the present application, the two pedals can be stretched in a horizontal state by rotating, and the pedals can be suspended at a high place by means of hooks, and the anti-swing bracket can be extended to make the anti-swing bracket contact with the electric pole or other equipment in the environment, so as to achieve a fixed pedal. It is beneficial to prevent the pedal from swaying from side to side, and solves the technical problem that the existing work focus point is not level when climbing only with foot buckles;

The invention discloses an efficient grinding machine special for sliding blocks. The efficient grinding machine special for the sliding blocks comprises a rodless air cylinder driving feeding system,a feeding system, a grinding system, a pushing system and a discharging system. The efficient grinding method for the sliding blocks comprises the steps of feeding, conveying, machining, pushing anddischarging. According to the grinding machine special for the sliding blocks, the automation technology is adopted, feeding, grinding and discharging are all completed automatically, and compared with a traditional machining mode, the efficiency is improved by 10-12 times; the grinding system adopts a high-strength grinding wheel, grinding and rough and fine grinding are completed at a time in afree state in a brand-new hydraulic motor chain type driving mode, meanwhile, the surface roughness of a finished product is higher, the precision is higher, the yield is higher, the efficiency and quality are truly improved, meanwhile, due to the fact that the machining efficiency is greatly improved, the number of machines is reduced, the one-time investment is saved, and the economic benefit isgreatly improved.
