MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202547095049 A) filed by Qualcomm Incorporated, San Diego, on Oct. 3, for 'photoacoustic device including a light guide system configured to transmit light through an electromagnetic interference (emi)-reducing layer.'
Inventor(s) include Tse Justin; Naing Htet; and Panchawagh Hrishikesh Vijaykumar.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "An apparatus may include a platen, an electromagnetic interference (EMI)- reducing system including a first EMI-reducing layer, a light source system and a receiver system. The light source system may include a light-emitting component, light source system circuitry and a light guide system and may be configured to emit light through the first EMI-reducing layer to a first platen area via a light pipe between the first EMI-reducing layer and the platen. The light guide system may include a light- directing element for directing light from the first EMI-reducing layer to the light pipe. The receiver system may be configured to detect acoustic waves corresponding to a photoacoustic response of a target object in contact with the first platen area to light emitted by the light source system. The first EMI-reducing layer may reduce a level of EMI emitted by the light source system circuitry that is received by receiver system circuitry."
The patent application was internationally filed on Apr. 11, 2024, under International application No.PCT/US2024/024146.
