Anti-Tampering Technology Compliments Battery Protection to Maximize Device Safety

In an increasingly connected world, the safety of electronic devices has become a major concern for both individuals and businesses. As devices are tasked with handling sensitive information and operating in diverse, often hazardous environments, ensuring their security is paramount. Two key aspects of device safety are critical data protection and physical safety measures. On the one hand, safeguarding sensitive data from unauthorized access or tampering is crucial to maintaining privacy and preventing breaches. On the other, protecting the physical integrity of devices, including their batteries and circuits, is essential to avoid malfunctions that could lead to dangerous accidents. 

On August 30th, 2024, a new patent filed by Hytera was published: “An anti-tamper circuit, control method and interphone are provided” (Patent No. CN118573382A). This innovative patent has attracted wide attention from industry stakeholders, underscoring the critical importance of both data and physical protection.

Critical Data Storage and Protection

Hytera's latest patent features a dual-power system design that uses a main battery and a backup battery to ensure a continuous power supply to critical storage components. This ensures that even if the main battery is removed, the backup takes over, preventing the loss of sensitive data until the device can be restored to a secure state. This approach guarantees the preservation of vital information in the event of tampering or accidental power loss.

At the core of this innovation is an advanced encryption mechanism that protects sensitive data. Hytera combines physical and software-based measures to protect storage components. If tampering was detected, the pathway switch would cut the power to ensure the erase of data within the storage module.

The design of the pathway switch underscores Hytera's focus on quick response mechanisms. Equipped with highly sensitive sensors, the switch monitors the physical state of the device in real-time. If the device's casing is illegally opened, the sensor immediately sends a signal to the control unit to activate the switch's disconnection mechanism. This combination of encryption and rapid response enhances the overall security of sensitive information, providing users with peace of mind.

Physical Safety Protection for the Device

Alongside data security, physical safety is equally crucial, especially in high-risk environments like construction sites, oil refineries, or emergency services, where devices like two-way radios are often used. In today's technology-driven world, the safety of electronic devices and their batteries is a top concern for both individual users and businesses. A defective battery or poorly designed circuit can lead to overheating, short circuits, or even explosions, putting lives at risk and threatening business operations. Beyond the immediate physical dangers, these malfunctions can result in significant financial losses from damaged equipment, downtime, or even legal liabilities. 

Hytera has a history of pioneering safety innovations, as seen in their patents related to explosion-proof designs. For example, Hytera filed a patent "A Battery Protection Device and Method" (Patent No. CN102170117B) in 2011. The patent introduces a charge-discharge control logic, a discharge control unit, first and second MOS transistors, and a feedback unit. The design is intended to delay the opening of the discharge switch to suppress transient high currents, preventing sparks during short circuits or sudden load changes.

Similarly, the patent "Intrinsically Safe Switching Power Circuit and Electronics" (Patent No. CN218850617U), filed in 2022, further enhances safety by incorporating a clamping circuit that regulates voltage. Each voltage-regulating clamping branch includes series-connected voltage-regulating components and at least one clamping component to regulate the voltage of the circuit. In the event of a fault or failure, this circuit clamps the inductor voltage, preventing excessive voltage across energy storage components, thus avoiding device overheating or sparks. This design enhances the safety and reliability of the circuit, meeting explosion-proof certification requirements.

Your Choices for Safety

To some extent, device security and safety is about making the right choices and purchases. Take two-way radio batteries for example, the original ones are specifically designed and rigorously tested to meet the exact specifications of the device, offering superior reliability, stability, and safety in a variety of operating conditions, including hazardous environments. By choosing original accessories and batteries, users not only extend the lifespan of their devices but also protect themselves and their teams from serious safety risks. Ensuring that every aspect of the device is engineered for reliability—from critical data protection to physical safety features—helps users navigate their operations with confidence.
