The US Patent & Trademark Office granted Apple patent that includes a wrist biometric sensor. This took place September 3rd 2019 and now Apple has come up with an all new form of biometric authentication that will be located on the inside portion of the watch band and will read skin texture patterns.
Patently Apple delves more into the patents of the band where the first patent describes a sensor built into the watch. This means that the watch could use infrared to build a thermal image of your wrist so as to identify the one wearing it.
However, the watch lacks a built-in biometrics for unlocking which you will find it common on other Apple devices. Without the sensor setup, one will be required to unlock the Apple Watch by putting in a PIN or one would synchronize it with the phone so that when you unlock your phone, the watch unlocks too. However with the sensors, all that is deemed unnecessary as it will open automatically.
The second patent of the Apple Watch is its ability to adjust itself while on an individual’s wrist. If the watch senses that it is sliding off while for example running, the watch will re-adjust itself and become tighter to the wrist. Tension around the Apple Watch could either tighten or loosed the wrist watch on command.
The wrist band will also be able to help users take their pulse by tightening the band completely so as to get the biometric reading. It will then after be able to loosen up so as not to cut off blood circulation from your wrist.
The final granted patent to the watch is a built-in light up indicator. You notice how whenever we get a text or an email our phones notify us even though the display light is off or when an alarm goes off even though the phone is off, same thing that will be happening to the Apple Watch.
The light indicators could be representing Activity App progress. It could also offer backlight for other icons such as running or swimming to indicate the particular activity that is being tracked or is in motion.
These are the three patents granted to Apple and one should not that some patents that are granted do not necessarily make it to the final product. It could be of reasons such as actualization and availability of resources.
