Abstract

This invention combines electropermanent magnets* built into the base of the device (such as laptop, smartphone or tablet, but can also include other devices of value such as lab equipment). This is combined with the laptops security system and when placed on a compatible surface, such as desk or boardroom table, the security system can be used to activate the magnets and secure the device in place.

Electropermanent Laptop Security

Today mobile computing devices are getting more and more portable, however the risk of theft is also increasing. The theft of a laptop of smart device results in loss and inconvenience from the hardware, but also the risk of sensitive data.

Current security devices for laptops are cumbersome. The industry standard is the Kensington Lock, which requires a reinforced slot in a structural part of the casing which is locked by a key or combination code. As Ultrabooks are getting thinner, the size of these locks has become a limited factor in the design. They are also inconvenient to carry and require a structural anchor-point to attach to, which often involves crawling around on the floor to attach to a desk leg. No similar physical security devices seem to exist for smartphones and tablet devices.

This invention combines electropermanent magnets* built into the base of the device (such as laptop, smartphone or tablet, but can also include other devices of value such as lab equipment). This is combined with the laptops security system and when placed on a compatible surface, such as desk or boardroom table, the security system can be used to activate the magnets and secure the device in place.

When combined with a presence location device, such as a Bluetooth watch or tag, or facial recognition, the computer can be set to engage the magnets and lock in place while the user is away from the device. When he or she returns, it can be automatically unlocked and repositioned as required.

Compatible surfaces must be built to certain specifications to meet the required magnetic properties etc.


*Note: Electropermanent magnets only require a voltage to be applied when changing state, rather than constantly like an electro magnent. They are described here: https://en.wikipedia.org/wiki/Electropermanent_magnet

This invention is made of a set of electropermanent magnets in the base of the laptop or other device, which are controlled by software in the laptop and activated depending on certain states. For example if the laptop is on a compatible surface, it may be set to lock in place via the magnets when the users moves more than 3m from the device and unlock...
