Title: Hoton How: Innovator in Broadband Circulators and RFID Security
Introduction
Hoton How is a notable inventor based in Belmont, MA (US), recognized for his contributions to the fields of broadband circulators and RFID security. With a total of 17 patents to his name, How has made significant advancements in technology that enhance performance and security.
Latest Patents
One of How's latest patents is titled "Method and apparatus of obtaining broadband circulator/isolator operation by shaping the bias magnetic field." This invention discloses improved techniques for using a shaped bias magnetic field over the active region of a ferrite stripline circulator/isolator circuit. The axial component of the bias field is decreased from the center toward the edge, accommodating changes in magnetization and fulfilling the requirements for broadband operation. Additionally, the radial component of the bias field is reduced to minimize the generation of non-circulation volume modes, resulting in a broad bandwidth with improved characteristics in insertion loss and isolation.
Another significant patent is the "Method and apparatus for implementing security protection over RFID." This invention provides improved techniques for equipping an RFID with security measures. Traditionally, RFID technology lacked security, making it vulnerable to tampering. However, How's invention allows an RFID device to memorize its original spatial position, generating an alarm signal if the position is changed without authorization.
