A surface and interior material identification technology based on dual-mode sensor

Abstract: In this paper, a novel hybrid-sensor integrating TENG and inductive sensor is proposed to acquire the triboelectric and inductive signals from different objects. A matching CNN algorithm was used to process the above signals in order to achieving highly accurate recognition. The identification accuracy of different solid surfaces reached 98.89% and the identification accuracy of different solution reached 95%. As a demonstration, we designed a real-time identification system for effective sorting of different items.

Collating machine and method

Abstract: A system for the accurate alignment of sheets of material relative to apparatus such as a machine for collating component layers or sheets uses an inductive sensor 104 at a known position on the apparatus to detect a metallic sensor or reference feature 102 in the sheet 100 and means 130a for moving the sheet 100 relative to the sensor 104. The system may use additional inductive sensors 104a, 104b, 104c, 104d, additional metallic sensor features 102 and additional moving means 130a, 130b to align the sheet 100. The system maybe used in the production of electronic or smart cards from layers carrying printing, security and electronic features including RFID and NFC technology such as an antenna and a chip. The metallic sensor feature 102 may be an antenna such as a spiral wound wire. Moving means 130 may be grippers, suction devices, rollers or pushers. Guides or rollers 106, 108 may help to accurately maintain the separation between the sheet 100 and the sensor 104. The sheet 100 may include a number of similar elements that will ultimately be divided up to produce separate cards.

Cabin door electronic system for ATM protection cabin capable of preventing people from getting trapped and implementation method thereof

Abstract: The invention discloses a cabin door electronic system for an ATM protection cabin for preventing people from getting trapped and an implementation method thereof. The system is characterized in that a cabin door controller unit is connected with a first human body inductive sensor and a second human body inductive sensor for detecting a human body in spaces at different heights from the cabin internal ground, a sound input circuit having a microphone arranged inside the cabin and a sound output circuit having a loudspeaker arranged outside the cabin; the first human body inductive sensor has the height of the detection space from the cabin internal ground less than that of the second human body inductive sensor, and steps are arranged in front of an ATM. The method is characterized in that during maintaining shielding of unlocking of a door entering button, when the time that an input sound signal amplitude value having the interval less than a stipulated value is larger than a threshold value is detected and identified to continuously reach the stipulated time, the accumulative time for detecting the human body by the second human body inductive sensor in the stipulated time accounts for 30% or less of the stipulated time, and no people are affirmed to be fainted to the ground in the stipulated time, a child is affirmed to get trapped, unlocking is performed, and voice helping information that the child gets trapped in the cabin is outputted by the loudspeaker outside the cabin.

Contactlessly operating electronic device

Abstract: The invention relates to a contactlessly operating device having a sensor, in particular an inductive, capactive, optical or ultrasonic sensor switch, having a defined response range inside which a control lug which approaches the sensor effects a sensor output voltage which varies within wide limits in a manner proportional to their separation from one another. In order to be able to connect such an analog device directly - without interposition of an analog-to-digital converter - to programmable controls or microprocessor controls in conjunction with improved interference immunity, the sensor output voltage is fed to an internal 2 -stage threshold-value generator having "n" digital outputs at which a digital output voltage can be tapped which corresponds to a subdivision of the response range into 2 subranges.

Design and Development of Inductive Sensor Mini Trainer Based on Arduino

Abstract: Sensor and Transducer is one of the subjects that must be followed by students of the Automotive Engineering Department, Faculty of Engineering, Padang State University, which weighs 2 credits. In accordance with the RPS for the Sensor and Transducer Course, there are several types of sensors that are the subject of study, one of which is an inductive sensor. Inductive sensor applications are applied in the automotive world such as Crankshaft Position Sensor (CKP), Camshaft Position Sensor (CMP), Vilocity Sensor. To make it easier to understand each sensor applied in the automotive world, students are required to master the basic concepts of the inductive sensor. One of the ways to increase student competence in the field of inductive sensors is the use of teaching aids during the learning process. Inductive sensor learning media in the Laboratory at the Automotive Engineering Department still uses analog processors, to support the development of digital technology today, so the authors provide an alternative by making teaching aids in the form of an Arduino-based Inductive Sensor Mini Trainer. This study uses the Research and Development (R&D) method which consists of Define, Design, Development, and Desseminate. The assembled inductive sensor mini trainer was tested for accuracy, and repeatibility test as well as feasibility test from media experts and users. The results of the research on the product trials carried out, obtained an accuracy level of 96.21%, the sensor output has linearity, the repeatibility test is obtained with an average of 0.1%. The level of product feasibility from Media Experts, is 94.68% and 96.23% from Respondents. So it can be concluded that the Inductive Sensor Mini Trainer is very suitable to be used as a learning medium.
