Israeli company develops handheld portable spectroscopy equipment to analyze food heat
Release date: 2015-10-21 There are a lot of apps and websites that let you calculate calorie intake yourself. This process is not only cumbersome but often inaccurate. However, starting next year, to calculate your calorie intake, you only need a simple scan. An Israeli company developed the handheld scanner Scio, which uses a beam of light to analyze the fat, carbohydrate and protein content of the food's "molecular characteristics." Scio was developed by Consumer Physics, which last year launched the equipment at Kickstarter. The company expects to begin selling the product next year, and Scio is now accepting the offer for $249. The device was also sold to over 1,000 companies, allowing them to produce apps for the device. Each molecule has its own unique mode of vibration that interacts with light to produce a characteristic optical feature, the near-infrared spectrum. In order to analyze the food, the user needs to hold the Scio with a light beam to illuminate the food to be analyzed. The device then transmits the data to the mobile phone via Bluetooth, and the mobile app looks for "features" in the food database to identify the food. Once the device recognizes the food, the information is fed back to the user's mobile phone. To accurately assess the calories of food, Yonghua also needs to determine the size of the food being scanned. Traditional spectrometers are large and cumbersome, and this portable version is a major breakthrough in this field. The Consumer Physics Corporation demonstrated the device at the Wired 2015 Technical Conference in London. The device can also be used in the emergency area to help first aid personnel identify the drug. The company's CEO Dror Sharon handheld device successfully identified Viagra tablets. He also said that the device not only recognizes the drug itself, but also distinguishes between aspirin and pure aspirin. The company is building “material databases†in different fields, such as food and medicine.

This article focuses on the advantages and classification of automated irrigation.

The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
