MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107556 A) filed by Chandigarh University on September 07, 2026, for A Stimulus Presentation Apparatus With Mechanically Enforced Observer Blinding.
Inventors include Shubham Sharma; and Ashita Chadha.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a stimulus presentation apparatus with mechanically enforced observer blinding for behavioural and psychological experiments. The apparatus comprises a cabinet frame (101) having a participant aperture (102) and an observer aperture (103), a stimulus carrier (104) configured to sequentially position a plurality of stimuli, an index detent (105), an occluder (106), a mechanical linkage (107), an actuator (108), and a ratchet wheel (109) with pawl (110). The stimulus carrier (104) is mechanically coupled to the occluder (106) such that a single operation of the actuator (108) advances the stimulus carrier (104) to a subsequent stimulus position while simultaneously moving the occluder (106) to conceal the stimulus from an observer. The index detent (105) positively locates the stimulus carrier (104), while the ratchet wheel (109) and pawl (110) provide controlled incremental movement and prevent reverse rotation. The apparatus is wholly mechanical and requires no electrical power.
