Apple has obtained a patent for gadgets with a “Round Radar-Antenna Array”, which introduces a brand new person interface that may acknowledge hand gestures

Patently Apple released a report this morning entitled “Apple Received a Patent for a Hand Gesture User Interface That Could Extend To Finger Gesturing & Beyond.” Released. While that patent focused on identifying hand gestures using a coherent light source and a random speckle pattern generator, much like the system behind Face ID.

Today, the US Patent and Trademark Office also issued a patent to Apple relating to radar measurements by an electronic device and techniques for making radar measurements using an electronic device with a 360 degree array of radar transmit and receive antennas. Field of view. The system also recognizes hand gestures, but this time with circular radar.

Technically, Apple’s patent covers an electronic device that takes radar measurements. The electronic device includes M separate radar transmitters and N separate radar receivers located in the electronic device, the M radar transmitters and the N radar receivers arranged in a circular architecture that provides 360 degree coverage in a horizontal plane, and where M and N are integers. In addition, the N radar receivers can be synchronized using a clock signal. During operation, subsets of the M radar transmitters send radar signals in succession, and when a given subset of the M radar transmitters is transmitting, at least a subset of the N radar receivers makes radar measurements.

By determining the location and / or the identity of the individual, the measurement techniques can facilitate improved operation of the electronic device. For example, These functions can enable the electronic device to monitor the environment and / or the person continuously or regularly, including any commands provided by the person (such as spoken commands and / or gestures).

In this way, the capabilities of the electronic device can enable a user interface that is responsive to the person without the person having to store predefined keywords or commands.

Additionally, based at least in part on the determined location, the electronic device 110 can listen directly to spoken commands from the person or can determine when the person is providing a command to an electronic device (e.g., through Recognizing a gesture or using the measured radar signals).

This can allow the person to control the electronic device without using keywords, such as a wake-up word, to activate the electronic device. Instead, The electronic device can provide ubiquitous sensing capability. In some embodiments, the particular vital sign or medical condition of the individual facilitates an additional service or application.

In some embodiments, the electronic device could be a smartphone, laptop, notebook, tablet, wireless speaker (HomePod mini), IoT device, smart appliance, set-top box, security device, or any other such electronic device).

Apple’s Patent 1 below is a block diagram illustrating an example of an electronic device that makes radar measurements; COWARDLY. FIG. 8 is a drawing illustrating an example of a circular architecture having 16 radar transmitters and 16 radar receivers in the electronic device of FIG. 1.

Apple’s Patent 9 is a drawing showing another example of circular beam shaping in the electronic device of FIG. 1.

This is an interesting patent. For more information, see Apple’s issued patent 10,928,498.
