MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517091963 A) filed by Renishaw Plc, Wotton-under-Edge, U.K., on Sept. 25, for 'position encoder apparatus.'
Inventor(s) include Gordon-Ingram, Iain, Robert; Fisher, Harrison, Clinton; and Gribble, Andrew, Paul.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "An encoder readhead for reading an encoder scale is described. The encoder readhead includes a detector, such as a one-dimensional optical imaging array, having a plurality of sensor elements (302) that generate a plurality of analogue sensor signals. A digitiser is provided for converting the plurality of analogue sensor signals into digitised sensor values and an incremental position generator (308) is configured to receive the digitised sensor values and to generate therefrom an incremental position output (310). The digitiser comprises a plurality of analogue-to-digital convertors (304) and the incremental position generator receives a plurality of the digitised sensor values from the plurality of analogue- to-digital convertors (304) in parallel. The plurality of analogue-to-digital convertors (304) and the incremental position generator (308) may both be provided on a first microchip (300). An absolute position generator (402) may be provided on a second microchip (400) to generate an absolute position output from the digitised sensor values. The encoder allows faster calculation of position and hence improved measurement accuracy."
The patent application was internationally filed on Mar. 15, 2024, under International application No.PCT/GB2024/050709.
