Weigh Platter Assembly with Parallax Based Off-Platter Detection - A simplified explanation of the abstract

This abstract first appeared for US patent application 18233494 titled 'Weigh Platter Assembly with Parallax Based Off-Platter Detection

Simplified Explanation

The patent application describes a weigh platter assembly that includes a weigh platter and an off-platter detection assembly.

  • The off-platter detection assembly consists of a light emission assembly, a light detection assembly, and a controller.
  • The light emission assembly has a light source that emits light along the lateral edge of the weigh platter.
  • The light detection assembly detects the light reflected from an object that extends across the light beam.
  • The light detection assembly includes a sensor offset from the light source and an aperture that limits the sensor's field of view along the lateral edge.
  • The controller is responsible for providing signals based on the values received from the sensor.
  • The controller provides a first signal in response to a first value received from the sensor.
  • The controller also provides a second signal, different from the first signal, in response to a second value received from the sensor.


Original Abstract Submitted

A weigh platter assembly includes a weigh platter and an off-platter detection assembly having a light emission assembly, a light detection assembly, and a controller. The light emission assembly has a light source to emit a light along a lateral edge of the weigh platter. The light detection assembly detects at least a portion of the light reflected from an object extending across the light beam and includes a sensor offset from the light source and an aperture positioned in front of the sensor and configured to limit a field of view of the sensor along the lateral edge. The controller is configured to provide a first signal in response to a first value received from the sensor and to provide a second signal, different from the first signal, in response to a second value.
