Latest Patents

One of Andrew's latest patents is a low power coin discrimination apparatus. This device is designed to detect and identify the denomination of a coin to activate various devices such as parking meters, telephones, or vending machines. Initially, the device remains in a low power, dormant state. When a coin is inserted, it triggers a switch that produces a wake-up pulse, activating a microprocessor. The coin then falls onto a piezoelectric element, which sends a signal to the microprocessor to activate a photoelectric sensor. This sensor determines the net cross-sectional area of the coin, while the microprocessor samples the output to detect the minimum light incident upon the sensor. The mass of the coin is also measured, and if both the light and mass outputs are within acceptable limits, the coin's denomination is recorded. Once the process is complete, the circuit returns to its original low power state.

Another significant invention by Andrew is a method and apparatus for a wrapping machine. In this design, a package is elevated into a film sheet stretched above an elevator. Side folding levers and a coordinated rear folder work together to fold three sides of the film sheet around the package. The design ensures that the edges of the film overlap correctly, providing a secure wrap. The infolding of the film is delayed at the rear edge of the package, allowing for a more efficient wrapping process. This innovative approach enhances the packaging efficiency and effectiveness.
