Whether you're decking the halls or buying gifts for the holidays, your preparations may involve something with a button battery. Button batteries (or disc batteries) are widely used to power a variety of everyday items around the home, such as watches, clocks, small remote controls, electronic candles, hearing aids, toys, keychains, musical greeting cards, children's audiobooks, and light-up or musical holiday decorations. These small, yet useful devices are certainly charming to look at, but they also pose a hazard that should not be ignored.

According to statistics from the Battery Ingestion Hotline, more than 3,500 people of all ages in the United States swallow button batteries each year. Although these batteries are small and usually not easy to notice, once swallowed, they can cause serious health problems, especially in children, where the consequences can be serious and even life-threatening.

Risks of swallowing button batteries

Once a child swallows a button battery, the battery releases electrical current and chemicals in the body, which can cause several serious consequences:

• Burns and corrosion: The alkaline substances in the battery can cause severe burns to the digestive tract, causing damage to the esophagus and stomach, and even possible perforation.

• Poisoning: Heavy metals inside the battery, such as mercury and cadmium, may enter the bloodstream and cause a poisoning reaction.

• Choking: If the battery gets stuck in the airway, it may cause difficulty breathing or choking.

• Organ damage: If the battery stays in the body for too long, it may cause organ damage or serious infection.

According to research, serious consequences can occur quickly within hours if a button battery is swallowed without prompt medical attention. Therefore, once an accidental swallowing occurs, parents need to react quickly and send the child to the doctor in time.

What should I do if my child swallows a button battery?

Since there is no way to know if the battery will penetrate or get stuck, it is important to seek medical help immediately.

• Call the emergency center for emergency medical assistance and try to remember the time when the battery was swallowed.

• Do not let your child eat or drink water to avoid food or liquids aggravating the injury. If your child swallows a button battery, do not let them vomit. This will make the reaction more severe.

• Do not use nose drops or ear drops to move the battery unless instructed by a medical professional.

• If the battery is still in the esophagus, an X-ray may be needed to locate it and dispose of it promptly.

How to prevent button batteries from being swallowed accidentally?

• Keep away from children: First, parents should store items containing button batteries out of reach of children. For example, place remote controls, electric toys, electronic devices, etc. in high places or lock them up.

• Choose products with safe designs: When buying children's toys and electronic devices, give priority to products with safer battery compartment designs. Some products have battery compartments with anti-tampering designs that require tools to open, which can effectively prevent children from contacting batteries.

• Check household items regularly: Parents should regularly check battery-powered devices at home to ensure that the battery cover is completely closed and undamaged. If the battery cover is loose or damaged, it should be repaired immediately.

• Educate children: As children grow up, they can be properly educated on safety to let them understand the dangers of button batteries and avoid putting them in their mouths.

• Dispose of batteries in a timely manner: If there are old button batteries at home, they should be properly discarded to avoid children's contact. For damaged batteries, parents should dispose of them in a timely manner to prevent children from swallowing them by mistake after picking them up.

The voltage drop ‌ is the decrease in voltage caused by the presence of resistance when the current passes through a resistor or conductor in a circuit.

The voltage drop is mainly caused by the following reasons.

1.‌Resistor. ‌When the current passes through the resistor, the resistor consumes part of the electric energy, which is converted into heat energy, resulting in lower voltage.

2.Current. The higher the current, the greater the voltage drop.

3.Wire length. The longer the wire length, the greater the resistance, the greater the voltage drop.

4.Wire cross-sectional area. The larger the cross-sectional area of the wire, the smaller the resistance and the smaller the voltage drop.

5.Wire material. Wires of different materials have different resistivity. The greater the resistivity, the greater the resistance, and the greater the voltage drop.

Voltage Drop will have a variety of effects on the lamp ‌, mainly including the following aspects of the impact.

1.Brightness drop. When the voltage is below the appropriate level, the brightness of the bulb will decrease. This is because the resistance in the bulb causes the voltage to be distributed to various parts, resulting in insufficient voltage, and the bulb cannot emit enough light.

‌2.Shortened life. Low voltage will cause the life of the lamp to be shortened. The lamp needs more current in the case of low voltage to emit enough light, which will accelerate the aging of the resistance, wire, circuit board and other parts of the lamp, thus shortening the service life of the lamp.

3.Flicker and burn. When the voltage is low to a certain degree, the bulb may flicker and even burn. This is because the lamp needs more current to drive in the case of insufficient voltage, and the temperature will rise, which is easy to cause short circuit or overload, resulting in the lamp burned.

The effect of the voltage drop problem on lighting is universal, including on farm lighting. And this impact will cause direct economic losses to farmers. Is there any way to avoid this effect?

The answer is yes. After the unremitting efforts of the company's research and development team, we finally developed a Smart Poultry Lighting Control System that can not be affected by the voltage drop. The control system is equipped with self-developed drive power supply and control system. The problem caused by voltage drop to lamps has been completely solved. This control box can not only adjust the brightness and timing of the light, but also realize the sub-area control of the light. The farmers who use Intelligent Poultry Lighting Control System are extremely satisfied with the convenience it brings to the farm.

Laying hens are chickens raised specifically to lay eggs for the supply of eggs. The main task of raising laying hens is to improve egg quality and maintain or increase egg production. Laying hens breeds should be selected robust, disease resistance, foraging ability, good egg quality, high egg production rate, and coarse feeding, adapt to the local environment of the local chicken.

The laying rate of hens is very important to farmers. However, sometimes the egg production rate will decrease for some reasons, resulting in economic losses for farmers. So, what causes the decrease in laying rate of hens?

There are many reasons for the decrease in laying rate of laying hens, and the following are some of the main factors.

Environmental Factor

1. Temperature change. Too high or too low temperature can affect the laying rate of hens. For example, high temperature in summer will lead to reduced feed intake and insufficient nutrient intake of laying hens, which will affect egg production. Cold winter may cause cold stress and physiological disorders.

2. Humid environment. Excessive humidity not only affects the normal metabolism of laying hens, but also may breed harmful microorganisms and cause diseases.

3. Poor ventilation. Poor ventilation facilities or insufficient ventilation will lead to the accumulation of harmful gases (such as ammonia, carbon dioxide, etc.) in the house, affecting the health of laying hens and reducing the laying rate.

Nutritional Factor

1. Feed quality. Poor feed quality, moldy deterioration or contamination will reduce the palatability of feed, reduce the feed intake of laying hens, and lead to a decrease in laying rate.

2. Nutrient deficiency. Insufficient protein, vitamins, trace elements and other nutrients in the feed will affect the normal physiological function of laying hens, and then affect the laying rate. For example, the imbalance between calcium and phosphorus can affect the formation of eggshells.

3. Feed mutation. Sudden change of feed will lead to digestive dysfunction of laying hens, resulting in indigestion, which will affect the laying rate.

Disease Factor

1. Infectious diseases. Chickens infected with infectious diseases such as avian influenza, Newcastle disease, infectious bronchitis, etc., can lead to a sudden decline in egg production. These diseases not only affect the egg production rate of laying hens, but also can cause a large number of chicken deaths.

2. Bacterial diseases: Bacterial diseases such as colibacillosis and salmonellosis can also affect the egg production rate of laying hens.

3. Parasitic diseases: Parasitic diseases such as coccidiosis and filariasis can also have a negative impact on the egg production rate of laying hens.

Management Factor

1. Poor feeding management. Feeding is not fixed time and quantity, insufficient drinking water, equipment damage and other feeding management problems will lead to a decrease in laying rate.

2. Stress factors. Stress factors such as abnormal noise, the presence of strangers, vaccination or deworming treatment can also reduce the laying rate of laying hens.

3. Unreasonable light. Insufficient light time or insufficient light intensity will affect the physiological function of laying hens, and then affect the laying rate. 

Now, let's increase egg production in a very simple way. By using our latest research and development product High-tech Intelligent Poultry Lighting Control Box 6020 connected to the Safe LED Poultry Light Bulbs, the farming farmer can adjust the lighting time and brightness to improve lighting condition, then improve the laying rate of laying hens.

Temperature changes significantly impact the frequency of quartz crystals. A well-designed oscillator compensates for these effects through temperature-compensated crystal oscillators (TCXO) or oven-controlled crystal oscillators (OCXO). Advanced applications often require TCXOs or OCXOs to minimize low temperature drift in crystal frequency, ensuring consistent performance in extreme environments.

2. Load Capacitance

The external load capacitance in the circuit affects the resonant frequency of the crystal oscillator. Variations in load capacitance lead to deviations in the output frequency. Designers must carefully select and stabilize the load capacitance to reduce its impact, especially in precision systems where frequency stability is paramount.

3. Mechanical Vibrations and Stress

Physical stress or vibrations can induce minor deformations in the crystal structure, leading to shifts in frequency. Proper mounting techniques and vibration-resistant designs can mitigate these effects.

4. Aging

Crystals naturally degrade over time due to molecular changes and contamination. This process, known as aging, causes a slow but steady drift in frequency. Selecting high-quality crystals with low aging rates is essential for long-term stability.

Crystal oscillators are a fundamental component in modern electronic circuits, widely used in devices such as computers, smartphones, and communication systems. They are essential for generating precise clock signals that synchronize the operation of electronic components. Among crystal oscillators, two main types are commonly discussed: active crystal oscillators and passive crystal oscillators.

What Are Active and Passive Crystal Oscillators?

Active Crystal Oscillators

Active crystal oscillators are self-contained modules that include a crystal resonator and an internal oscillation circuit. These oscillators generate clock signals directly without requiring additional external components. The internal circuit usually comprises an amplifier and feedback network, which help sustain the oscillations initiated by the crystal.

Key features of active crystal oscillators:

· They are pre-configured and ready to use.

· They generate output signals with a specific frequency determined by the crystal inside.

· They typically operate at higher frequencies compared to passive oscillators.

Passive Crystal Oscillators

Passive crystal oscillators, also referred to as crystal resonators, are simpler components that consist only of a quartz crystal. Unlike active oscillators, passive ones require an external circuit (e.g., a microcontroller or discrete components like resistors, capacitors, and amplifiers) to function. The external circuit excites the crystal to produce oscillations.

Key features of passive crystal oscillators:

· They rely on external components to generate oscillations.

· They are more basic and compact in design.

· They are typically used in lower-frequency applications.

  Working Principles of Active and Passive Crystal Oscillators

Active Oscillator Working Principle

Active oscillators function as integrated modules where the quartz crystal and oscillation circuit work together to generate a stable frequency. The crystal acts as a frequency-determining element, while the internal feedback amplifier sustains oscillations. The output signal from an active oscillator is a clean, high-frequency waveform, often used directly in digital systems.

Passive Oscillator Working Principle

Passive oscillators operate by exploiting the piezoelectric property of quartz crystals. When an external AC voltage is applied across the crystal, it vibrates at its natural resonant frequency. The resonant frequency is determined by the crystal's physical dimensions and cut. The oscillation signal is then amplified and conditioned by external circuitry to achieve the desired waveform and amplitude.

Differences Between Active and Passive Crystal Oscillators
