A pill counting device includes a step feeder having moveable slats interleaved with fixed slats. The movable slats are vertically offset from one another and are configured to move vertically between top platforms of adjacent fixed slats to carry pills vertically up the step feeder. A top movable slat orients a subset of the plurality of pills into a row of pills to be fed into a count chamber. A camera configured to capture an image of a pill of the individual pills as it falls through the count chamber. The device further includes a control system configured to control movement of the movable slats and to control capturing of images by the camera. The control system is further configured to calculate a characteristic of the pill from the image, and to increment a pill counter in response to the characteristic of the pill meeting predefined criteria.

An object counting device adjusts a signal to account for noise to improve object counting accuracy. A controller receives an electromagnetic radiation (e.g., light) intensity signal from radiation detectors and determines that its value is within a voltage threshold, thereby indicating that no object is passing through the radiation. The controller determines a derivative of the signal and that the derivative is less than a derivative threshold level for at least a predefined time. The controller then updates a base noise floor value to be the value of the radiation intensity signal to account for particles within a path of the electromagnetic radiation to improve an object counting accuracy. In some embodiments, the processor can scale the received radiation intensity signal in accordance with the updated base noise floor value.

An adaptive measurement and calculation method for luminescence values of a chemiluminescence analyzer is provided. A fixed step length is adopted for continuous multi-point reading to obtain a complete correspondence diagram of detection positions and luminescence values. Two nearest luminescence values on the left and right sides of a maximum value are selected, the nearest luminescence values on both sides are connected to form a straight line, and an intersection of two straight lines is taken as an approximate maximum luminescence value. The measurement and calculation method can adapt to random positions of the detected object, and stably obtain the approximate maximum luminescence value, thus reducing increased complex hardware design and cost to confirm accuracy of the measurement position.
