Latest Patents

One of his latest inventions is the Blackjack scanner apparatus and method. This module is designed to announce when a dealer has blackjack without exposing the face of the dealer's down-card. The module scans a character from the dealer's face-down standard playing card, compares the result with a set of references, and identifies the down-card. It also receives input from the dealer regarding the identity of the dealer's up-card, announcing whether the dealer has blackjack or if the hand continues. The design allows the dealer to slide the down-card across the table onto the scanner without lifting it, thus maintaining the card's confidentiality. Additionally, the module effectively removes noise generated by a casino's environment during the scanning process and optimizes the scan by controlling the light intensity emitted by its components.

Another significant patent is the subranging A/D converter with converging digitally controlled voltages. This device generates high and low voltages using two digital-to-analog converters (DACs). A voltage divider produces multiple reference voltages, which are then compared to the analog voltage that needs conversion. The process involves a clocked logic circuit that generates an intermediate digital signal indicative of the analog value relative to the reference voltages. This innovative approach allows for precise voltage adjustments until the reference voltages converge to match the analog voltage.
