US Patent 8,781,610: Method of ball game motion recognition, apparatus for the same, and motion assisting device

• Title: Method of ball game motion recognition, apparatus for the same, and motion assisting device
• Assignee: Zepp North America Inc. (Current), Hong Kong Zepp Holding Ltd (Current), Zepp Labs Inc (Original)
• Inventors: Zheng Han
• Filing Date: October 7, 2011
• Issue Date: July 15, 2014
• Abstract: The invention provides a method of ball game motion recognition, an apparatus for the same, and a motion assisting device. The method comprises: obtaining motion parameters corresponding to each sampling time for a motion; extracting feature points according to predetermined feature point recognition tactics utilizing the motion parameters obtained, in which the feature point recognition tactics comprise recognition tactics of at least three types of the feature points, comprising: power-assisting path early stage corresponding feature point, motion top point corresponding feature point, and ball hitting time corresponding feature point; and recognizing the motion as a predetermined ball game type if the feature points extracted satisfy feature point requirements of the predetermined ball game type.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method Claim): This claim describes a method for recognizing a ball game motion. It involves:

  1. Obtaining motion parameters: Gathering data (like acceleration, velocity, position, and stance) for a motion at various points in time.
  2. Extracting feature points: Identifying specific key points within the motion using predefined rules. These rules must include tactics for at least three types of feature points:
     • The start of the power-assisting path (e.g., the beginning of a backswing).
     • The top point of the motion (e.g., the peak of a swing).
     • The ball hitting time (e.g., the moment of impact).
  3. Recognizing the motion: Determining if the extracted feature points meet the requirements for a specific type of ball game (e.g., golf swing, soccer kick), thereby classifying the motion.

• Independent Claim 10 (Apparatus Claim): This claim describes an apparatus designed to perform the ball game motion recognition method. The apparatus includes:

  1. A parameter obtaining unit: A component configured to get motion parameters for a motion at different sampling times.
  2. A feature point extracting unit: A component that extracts feature points based on predetermined recognition tactics, which must include tactics for the same three types of feature points as in Claim 1 (power-assisting path early stage, motion top point, and ball hitting time).
  3. A motion recognizing unit: A component that recognizes the motion as a predetermined ball game type if the extracted feature points satisfy the specific requirements for that game type.

• Independent Claim 19 (Motion Assisting Device Claim): This claim describes a motion assisting device that integrates the recognition functionality. The device comprises:

  1. A sensor device: This device samples motion data (including acceleration) of an object at various times.
  2. A motion parameter confirming device: This device takes the motion data from the sensor, calculates the full motion parameters (acceleration, velocity, position, and stance) for the object at each sampling time, and then sends these parameters to the ball game motion recognition apparatus.
  3. The apparatus for ball game motion recognition: This is the apparatus described in Claim 10, which then uses the motion parameters to recognize the type of ball game motion.

Uncertainty Note:
The search for CAFC 2026 dockets for patent number 8781610 did not yield specific litigation results directly mentioning this patent number. The results provided general information about CAFC intellectual property cases and patent case summaries for various other patents in 2026. Therefore, I cannot definitively confirm if US8781610 is currently involved in any active litigation in the CAFC for 2026 based on the provided search results.
