Publication number: 20240077780Abstract: This disclosure provides a window controller that includes a command-voltage generator that generates a command voltage signal, and a pulse-width-modulated-signal generator that generates a pulse-width-modulated signal based on the command voltage signal. The pulse-width-modulated signal drives an optically-switchable device. The pulse-width-modulated signal comprises a first power component having a first duty cycle and a second power component having a second duty cycle. The first component delivers a first pulse during each active portion of the first duty cycle, and the second component delivers a second pulse during each active portion of the second duty cycle. The first pulses are applied to a first conductive layer and the second pulses are applied to a second conductive layer. The relative durations of the active portions and the relative durations of the first and second pulses are adjusted to result in a change in an effective DC voltage applied across the optically-switchable device.Type: ApplicationFiled: September 13, 2023Publication date: March 7, 2024Inventor: Stephen Clark Brown

Publication number: 20240077781Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication and augment existing memory systems to allow them to be both high capacity and high bandwidth simultaneously.Type: ApplicationFiled: September 5, 2023Publication date: March 7, 2024Inventors: Mitchell A NAHMIAS, Michael J.

Publication number: 20240077783Abstract: An image capturing apparatus capable of reducing exposure variation in opposite end areas of an image when photographing is performed with flash light emission while shortening a flash synchronization time. A system controller determines a shutter speed for flash light emission photographing. The system controller selectively executes first control for controlling a traveling speed of a front curtain of a shutter and a traveling speed of a rear curtain of the shutter to the same speed, and second control for controlling the traveling speed of the front curtain to be higher than the traveling speed of the rear curtain. Before flash light emission photographing is performed, the system controller determines which of the first control and the second control is to be adopted according to the shutter speed.Type: ApplicationFiled: August 18, 2023Publication date: March 7, 2024Inventor: Yukihiro Matsumoto

Publication number: 20240077784Abstract: Described is phased metalens depth of focus increase for camera focusing. An objective camera lens is configured to provide a focus window across multiple radial zones within a field of view. A camera imager is configured to capture an image of the field of view. When at least two of the radial zones have different back focal lengths relative the imager and the objective lens, a phased metalens is positioned between the objective lens and the camera imager. The metalens is configured to compensate for defocus caused by the different back focal lengths by increasing, across the radial zones within the field of view, a depth of the focus window. The metalens improves focus across the field of view, which prevents variations in objective lens characteristics from reducing image quality.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Ronald M. Taylor, Morgan Daniel Murphy
