Presentation Transcript
project overview
Project Overview
  • Autonomous robot with multiple modes of operation
    • Follow, run away, manual control
  • Infrared sensors to detect warm bodies
  • Ultrasonic sensors to avoid obstacles
  • Bluetooth transmission of infrared-array and movement data
  • Battery-powered with fuel gauge
patent liability analysis
Patent Liability Analysis
  • Major Functions Considered:
    • IR Sensor array allows the robot to autonomously follow/run away from targets identified as warm bodies
    • Movement control and IR data stream transmitted via bluetooth
    • Avoidance of obstacles by use of several ultrasonic sensors
  • Search for patents with similar functionality to the Infrarat
possible infringement 6829370
Possible Infringement:<6829370>
  • Filed November 28, 2000 by Honeywell International Inc.
  • The presence of a human body in the scene is determined by comparing the reflection of at least one region of the scene using an infrared sensor array
possible infringement 68293701
Possible Infringement:<6829370>

Claims:

  • A detection method that detects reflection from a scene in Infrared and determines the presence of a human body
  • Detecting infrared reflection from at least one region of the scene comprising of a face region of the human body
  • A human body detection system comprising of an infrared camera which provides an image representing the region where the presence of a human body has been detected

Similarities:

    • Uses infrared cameras to detect a facial region of the human body
    • Makes use of a threshold for determining the presence of a human body
possible infringement 6137407
Possible Infringement:<6137407>
  • Filed November 16, 1999 by Nikon Corporation of Tokyo
  • Humanoid detector and method that senses infrared radiation and subject size
    • If the size of a moving body is greater than that of a small animal, the detected infrared radiation indicates that the moving body is a heat producing body
possible infringement 61374071
Possible Infringement:<6137407>

Claims:

  • A human body detection method, comprising the steps:
    • detecting infrared radiation in the surveillance area
    • determining a size of the moving subject
    • providing a decision signal that is indicative of a human body in the surveillance area when the size of the moving subject exceeds a predetermined size and the detected infrared radiation exceeds a predetermined value simultaneously
  • Method of humanoid detection based on the size of the moving object in infrared radiation is patented

Similarities:

    • Method of detection using number of pixels upon which a humanoid body would be imaged by a lens that focuses incident light on an array of photodiodes in a sensor element
possible infringement 8020657
Possible Infringement:<8020657>
  • Filed October 20, 2006 by iRobot Corporation
  • Systems and methods for obstacle avoidance
    • Teleoperation (Manual)
    • Waypoint navigation
    • Follow
    • Obstacle Detection
possible infringement 80206571
Possible Infringement:<8020657>

Claims:

  • A robotic control unit comprising of:
    • A sensor for detecting object data representing obstacles
    • Determine vehicle actions based on incoming sensor data
  • The control unit comprises of a processor and memory that has executable code
  • Control unit outputs control signals to vehicle motors

Similarities:

  • Method of navigation and use of teleoperation via bluetooth
  • Follow and Manual modes
possible actions
Possible Actions
  • Remove functionality
    • Unfeasible since the Infrarat relies on the use of all its sensors to navigate its surroundings
  • Change implementation technique
    • By using different methods of detection, the device would no longer fall under Literal infringement and instead be under the Doctrine of Equivalents
  • Obtain licenses or pay royalties to owners of patents
    • If the device were to go to market, this would be a viable option
