America's latest granted interesting patent: skin implant diagnostic device

This week, the U.S. Patent Office approved 5426 patents, according to Nanjing Huaxun. Each patent adds something new to the human knowledge base. Obviously, we can't introduce these nearly 6000 new patents, but we can learn about some very interesting patents. Here are the five most interesting patents picked by the PatentYogi team: skin-implanted diagnostic devices (from Google). Blood tests require patients to make appointments, wait in line, and then spend hours getting test results. Now, Google is going to change this way of testing.

The company has applied for a skin implant diagnostic system that can analyze a patient's blood, sweat or tissue fluid at the implant site and then monitor its physiological parameters. In addition, the system is equipped with an antenna that can send and receive wireless signals.

According to Nanjing Huaxun, the operation of the skin implant diagnostic system is controlled by the reader, which will be able to measure and collect blood parameters at different time periods without continuous energy supply to the sensor.

Replacing existing RF communications in combat missions with optical communications (from US military)

In close combat, soldiers can communicate using radio frequency (RF) communications. Good communication not only assists in the successful completion of the mission but also minimizes the number of casualties.

However, the RF communication may be tracked by the enemy, at which point the system may cause harm to the combat soldier. So, the United States thought of using optical communication.

Optical communication is a system that uses laser to expand communication. Soldiers will wear a lightweight headgear equipped with an optical transceiver containing 2 or more laser-driven receivers and 2 or more non-visible light-emitting diodes (LEDs).

The LED will encode the audio signal of one of the soldiers into a signal and then transmit it to the other soldier in the form of a laser. At this time, the other soldier's laser-driven receiver will decode the optical signal into an audio signal. In addition, the receiver can send the decoded data to a user interface such as a smart phone.

In addition, optical communication will also be possible to join the biometric authentication mechanism.

Interactive Textiles (from Google)

Traditional touchpads generally do not have flexibility, and if you want a flexible touchpad, the cost will be relatively high. This also limits the use of touch sensors for electronic devices such as smartphones, tablets, and computers. Google's Advanced Technology and Program (ATAP) is developing a technology that can break this limit and make touch input very common-Project Jacquard.

Under this project, Google has developed an interactive textile with touch input. It can perform tasks such as adjusting the volume, pausing movie playback on the TV, and selecting web pages on the desktop.

Thanks to the flexibility of textiles, this interactive textile can also be easily integrated into interactive objects, such as clothing, bags and hats.

According to the newly published patent documents, the top and bottom layers of this interactive textile establish communication through conductive threads. When they are connected, the wires of each layer will form a capacitive touch sensor, which can detect the touch input signal.

The system's support for gestures will allow users to create a variety of gestures to carry out a variety of activities.

Multivalent Malaria Vaccine (from US Army)

Malaria is considered one of humanity's greatest enemies. In all, more than 50 billion people have died from the disease throughout human history. Even now, more than 0.2 billion people still suffer from the disease every year, and more than 600,000 people die from it.

In this regard, it seems that the US military has developed an effective way to combat malaria. It is understood that the US military has successfully developed a multivalent malaria vaccine, which can overcome some of the problems and defects faced by existing vaccines.

The vaccine can be used at any stage, and after injection, it can alleviate the severity of the disease, the frequency of the disease, the symptoms or the duration of the complications. In this way, doctors can develop multiple treatment plans for patients in an hour, a day, a week, a month or a year.

3DTV image quality has been greatly improved (from Google)

Google began to shift its development goals to the TV field. After creating an interactive TV experience, Google now intends to improve the 3D image quality of the TV. Anyone who has seen 3D must be able to realize that when the picture changes from 2D to 3D, it will darken. This is because the 3D glasses worn by people during viewing filter out some light, and the depth perception of each audience is different, and Google's latest patent will solve these problems.
