Publication number: 20220382017Abstract: Systems and methods according to one or more embodiments are provided for annealing a chalcogenide lens at an elevated temperature to accelerate release of internal stress within the chalcogenide lens caused during a molding process that formed the chalcogenide lens. In particular, the annealing process includes gradually heating the chalcogenide lens to a dwell temperature, maintaining the chalcogenide lens at the dwell temperature for a predetermined period of time, and gradually cooling the chalcogenide lens from the dwell temperature. The annealing process stabilizes the shape, the effective focal length, and/or the modulation transfer function of the chalcogenide lens. Associated optical assemblies and infrared imaging devices are also described.Type: ApplicationFiled: August 12, 2022Publication date: December 1, 2022Inventors: Alan D. Kathman, William J. Hall, Erika Goransson, Todd E. Rixman, Bengt Jervmo, Bo Dahllof, Stefan Gustavsson, Leif Sommar, Olof Holmgren, Hans Ostling

Patent number: 10306348Abstract: Techniques for mute pattern injection for a pulse-density modulation microphone are described. In one or more implementations, a pulse-density modulation (PDM) microphone includes a transducer that receives a pressure wave and produces an analog signal that represents the pressure wave, an analog-to-digital converter (ADC) that receives the analog signal from the transducer and converts the analog signal into a digital PDM signal. The PDM microphone also includes a pattern generator that generates a digital mute signal, a controller that outputs control signals, and a multiplexer that receives the control signals, the digital mute signal, and the digital PDM signal. The multiplexer transmits the digital mute signal or the digital PDM signal, responsive to the control signals.Type: GrantFiled: June 1, 2017Date of Patent: May 28, 2019Assignee: QUALCOMM IncorporatedInventors: Bengt Stefan Gustavsson, Hui-Ya Liao Nelson
