Publication number: 20240118052Abstract: A pneumatic arrow gun has a gun body, an arrow, a positioning sleeve, and a connecting wire. The arrow is for inserting into an air tube of the gun body. The positioning sleeve is temporarily mounted around the air tube, and the arrow is disposed through the positioning sleeve. The connecting wire connects the gun body to the positioning sleeve. Because the positioning sleeve is temporarily mounted around the air tube, the arrow slides forward relative to the positioning sleeve after triggering. When triggering the arrow, the connecting wire naturally dangles. When the arrow detaches from the air tube, the positioning sleeve located at a nock of the arrow due to the sliding of the arrow. Therefore, a rebound of the arrowhead is prevented. The safety and the shooting stability are ensured. Further, the arrow is easily retrieved by the connecting wire.Type: ApplicationFiled: December 21, 2022Publication date: April 11, 2024Inventors: Li-Wei CHEN, Tsang-Yao LU

Patent number: 11823145Abstract: Methods and systems are presented for providing a framework to securely integrate third-party logic into electronic transaction processing workflow. Third-party programming code that implements different third-party logic may be obtained and stored in a repository. A transaction processing request is received from a third-party server, and an instance of a transaction processing module is instantiated within an operating runtime environment to process a transaction according to a workflow. When the instance of the transaction processing module has reached an interruption point, the instance of the transaction processing module is suspended, and a third-party programming code is executed within an isolated runtime environment. The third-party programming code is configured to provide an output value based on attributes of the transaction. The instance of the transaction processing module then determines whether to authorize or deny the transaction based in part on the output value.Type: GrantFiled: November 30, 2020Date of Patent: November 21, 2023Assignee: PayPal, Inc.Inventors: Shek Hei Wong, Chun Kiat Ho, Li Wei Lu
