Abstract
An activity sensor system includes a library that stores image information. A low power artificial intelligence based image sensor captures images from a first location at a first image resolution. The sensor has access to the library that stores image information. The sensor is able to recognize images based on the image information in the image library.
Claims15
An activity sensor system, comprising:
- a library that stores image information;
- a first sensor that captures images from a first location at a first image resolution, the first sensor having access to the library that stores image information, the first sensor being able to recognize images based on the image information in the library;
- a second sensor that captures images from the first location at a second image resolution, where the second image resolution is higher than the first image resolution;
- a power management block that controls power to the second sensor;
- and
- a controller that manages the power management block;
- wherein in a sleep mode, the first sensor captures images, but the second sensor does not capture images;
- and
- wherein when in the sleep mode, the first sensor detects a predetermined image, the power management block supplies power to awaken the second sensor so that the second sensor captures images from the first location and is no longer in the sleep mode.

An activity sensor system, comprising:
- a library that stores image information;
- a low power artificial intelligence based image sensor that captures images from a first location at a first image resolution, the low power artificial intelligence based image sensor having access to the library that stores image information, the low power artificial intelligence based image sensor being able to recognize images based on the image information in the library, the low power artificial intelligence based image sensor including a pixel array that consumes less than seven microwatts of power;
- a power management block that controls power to the low power artificial intelligence based image sensor;
- and
- a controller that manages the power management block;
- wherein when the low power artificial intelligence based image sensor detects a predetermined image, the activity sensor system notifies a user.
