Patent number: 11841268Abstract: Aspects relate to a compact material analyzer including a light source, a detector, and a module including a first optical window on a first side of the module, a second optical window on a second side of the module opposite the first side, and a light modulator. The light source produces input light at a high power that is passed through the first optical window to the light modulator. The light modulator is configured to attenuate the input light, produce modulated light based on the input light, and direct the modulated light through the second optical window to the sample. The modulated light produced by the light modulator is at a lower power safe for the sample. The detector is configured to receive output light from the sample produced from interaction with the modulated light through the second optical window and to detect a spectrum of the output light.Type: GrantFiled: February 1, 2022Date of Patent: December 12, 2023Assignee: SI-WARE SYSTEMSInventors: Yasser M.

Patent number: 10120134Abstract: A micro-optical bench device is fabricated by a process that provides control over one or more properties of the micro-optical bench device and/or one or more properties of optical surfaces in the micro-optical bench device. The process includes etching a substrate to form a permanent structure including optical elements and a temporary structure. The shape of the temporary structure and gaps between the temporary structure and permanent structure facilitate control of a property of the micro-optical bench and/or optical surfaces therein. The process further includes removing the temporary structure from an optical path of the micro-optical bench device.Type: GrantFiled: February 18, 2016Date of Patent: November 6, 2018Assignee: SI-WARE SYSTEMSInventors: Bassam Saadany, Yasser M.

Publication number: 20070121531Abstract: Disclosed is a hybrid wireless communication system and a communication method in the system. The system supports time and frequency division duplexing modes and includes a base station having a cellular communication range based on a cellular mode and mobile stations within the cellular communication range. The base station divides each available frequency resource into frames for communication, and each frame switches between a real-time service mode and a non-real-time service mode at a switching time within the frame. Communication is performed with the mobile stations within the cellular communication range via at least one of an uplink and a downlink in the real-time service mode of each frame according to the frequency division duplexing mode. Communication is performed with the mobile stations via the uplink and the downlink in the non-real-time service mode of each frame according to an ad hoc mode based on the time division duplexing mode.Type: ApplicationFiled: September 8, 2006Publication date: May 31, 2007Applicants: Samsung Electronics Co., Ltd., The University Court of the University of EdinburgInventors: Yeon-Woo Lee, Sang-Boh Yun, Harald Haas, Khaled Hassan, Stephen McLaughlin
