Title: Prithivirajan Sadhasivam: Innovator in Mobile-Based Building Access

Introduction

Prithivirajan Sadhasivam is an inventor based in Tamil Nadu, India, whose patent work focuses on using mobile devices to manage secure building access. He is associated with Honeywell International Inc. His portfolio includes 2 patents.

Latest Patents

Sadhasivam’s listed patents describe systems that use a mobile device as an access credential. In “Method and System for Controlling Building Access Using a Mobile Device,” wireless access points receive an identifier based on the device’s International Mobile Equipment Identity (IMEI) and determine the device’s location. A door can be electrically unlocked when the device is within a specified proximity and its identifier is linked to a user with access rights. The system also employs techniques to detect possible tailgating.

“Building Access Using a Mobile Device” describes a related approach. The mobile device determines its location using characteristics of signals received from a wireless access point, then communicates its location and IMEI-based identifier. The door unlocks when the device is sufficiently close and the associated user is authorized.

Career Highlights

The patents highlight Sadhasivam’s work at the intersection of mobile technology, location awareness, and physical security. By combining device identification with proximity checks and access permissions, the described systems aim to make entry control more convenient while supporting security measures.

Collaborations

Sadhasivam is associated with Honeywell International Inc. His listed coworkers include Thiruppathi V and Vikramraj Sivaram.

Conclusion

Prithivirajan Sadhasivam’s patent work centers on mobile-based building access systems that connect device identity and location with user authorization.
