"Ultra Sonic Blaster"@en . "The device was first mentioned in \"The Luminous Fish Effect\" by Mary Cooper while she was telling a story about Sheldon's childhood. Sheldon was devastated when the government inhibited his nuclear reactor work. Then he built a \"sonic death ray\" which did not slow down the neighbor kids, but pissed of their dog. In \"The Ornithophobia Diffusion\", the Ultra Sonic Blaster is a high-frequency tone generator Sheldon uses on the Black-throated Magpie-Jay (later known as Lovey-Dovey) on his window sill in an attempt to scare it away. The device was set up by Howard, who dubbed it a \"Bird Death Ray\", but it fails to execute its intended purpose, instead cracking the apartment window and not affecting the blue jay at all."@en .
