Patent number: 11955966Abstract: An analog input device including at least one mounting panel and a matrix of analog push button assemblies mounted thereon. Each analog push button assembly including an analog pressure sensor including a pressure reception arrangement having an optical sensing sub-arrangement configured to measure an amount of light varied according to a pressure sensed at the pressure reception arrangement and an output terminal for outputting an analog signal corresponding to the amount of light measured, and a plunger element configured to exert the pressure on the pressure reception arrangement. The analog input device may include a multiplexer including an input side coupled to the push button assemblies and an output side; an analog-to-digital converter coupled to the output side of the multiplexer; a processor coupled to the analog-to-digital converter and configured to output a data packet; and a communication interface configured to transmit the data packet to a host computing device.Type: GrantFiled: August 23, 2022Date of Patent: April 9, 2024Assignee: Razer (Asia-Pacific) Pte. Ltd.Inventors: Chung Wei Lee, Thuan Teck Tan, Wenliang Yang, Alvin Sim, Kok Kiong Low, Ling Duan, Christopher Mitchell

Publication number: 20240013637Abstract: The wrist rest may include a base structure; at least two flexible supports extending from the base structure; a vibration assembly supported on the at least two flexible supports in a manner such that the vibration assembly may be spaced apart from the base structure; and a cushion assembly including a cushion disposed over the vibration assembly in a manner so as to conceal the vibration assembly between the base structure and the cushion. The cushion may be secured to the base structure. The at least two flexible supports may be configured to isolate the base structure from a vibrating motion of the vibration assembly. A surface of the vibration assembly directed towards the cushion assembly may move relative to a corresponding surface of the cushion assembly in a manner so as to allow the vibration motion of the vibration assembly to be sensed through the cushion.Type: ApplicationFiled: September 19, 2023Publication date: January 11, 2024Inventors: Kok Kiong LOW, Chang Sern GWEE, Alvin SIM

Publication number: 20230405369Abstract: According to various embodiments, a face mask includes a cover shield, a microphone, a transceiver and a controller. The cover shield is shaped to cover nose and mouth of a wearer. The cover shield has an inner surface that faces the wearer when the cover shield covers the nose and the mouth of the wearer. The microphone is coupled to the inner surface of the cover shield. The microphone is configured to receive sound waves and further configured to generate audio data based on the received sound waves. The transceiver is configured to communicate bidirectionally with a mobile device. The controller is configured to control the transceiver to transmit the generated audio data to the mobile device.Type: ApplicationFiled: July 16, 2021Publication date: December 21, 2023Inventors: Lionel LIM, Gil Palma Jr. GUERRERO, JR., Alvin SIM, Kah Yong LEE
