Abstract: A system and method for measuring the optical phase of incident light using direct detection and for producing speckle-free images, designed for use with coherent illumination and reflective imaging geometries. Applications include speckle mitigation for active imaging, resolution enhancement using synthetic aperture methods, and digitally correcting aberrations in images or refocusing. The system hardware combines pupil-plane phase modulation with dual-plane direct-detection measurements of the image and pupil-plane intensities. The reconstruction software uses a regularized-inversion estimation framework that couples a data-fidelity model, a physics-based model for rough surface scattering of coherent light, and convolutional neural network model for natural images. The regularized inversion framework is solved iteratively using alternating projection.

Abstract: The present disclosure provides systems and methods for monitoring and correcting a condition of an engine. A system for monitoring an engine comprises a plurality of sensors each coupled to a cylinder of the engine and configured to detect pressure data from each cylinder, a controller coupled to the sensors and configured to receive the pressure data and a monitor coupled to the controller for displaying the pressure data. The controller comprises a processor and a computer-readable data storage device. The storage device stores program instructions that, when executed by the processor, stores the pressure data captured by the controller and parses or combines this data into at least one parameter that represents the condition of the engine and/or summarizes one or more issues that may affect engine performance. This provides valuable information to the user(s) in real time, allowing the user(s) to make immediate correction actions to the engine.

Abstract: An adjustable assembly includes a golf club shaft, a golf club head having a hosel portion with a hosel opening, a hosel insert, a shaft adapter, and a fastener. The hosel insert is secured to the hosel portion and includes at least one inwardly extending pawl. The adapter extends about a longitudinal axis, and defines a shaft opening. The adapter includes outwardly projecting teeth aligned with the hosel insert. Each tooth includes leading and trailing surfaces. The leading surface is shaped to enable rotational movement of the adapter about the axis with respect to the hosel insert in a first rotational direction. The trailing surface is shaped to selectively engage the pawl to inhibit rotational movement of the adapter with respect to the hosel insert in a second rotation direction that is opposite the first direction. The fastener is releasably coupled to the head and the adapter.

Abstract: The present invention is a desiccant system for controlling moisture in a solar collector. The desiccant system has a desiccant bed enclosed within a housing, and is thermally coupled to the solar collector as well as being fluidly coupled to it through an orifice. Waste heat from the solar collector is conducted to the desiccant system and is used to regenerate the desiccant bed. The desiccant system includes moisture barriers which cause moisture from the desiccant to preferentially be released to the external environment rather than entering the solar collector.

Abstract: The present invention provides an environmental control system for controlling moisture in a solar energy collector. The environmental control system facilitates the flow of air within and through the solar energy collector by using and enhancing a thermal gradient within the solar energy collector caused by exposure to sunlight. Two or more orifices are located in an enclosed solar energy system to permit air to enter, circulate and remove moisture from the system. The position of the two or more orifices and a thermal gradient generated by the solar energy collector facilitates this process.

In some aspects, a portion of the shield element may be disposed between the substantially planar surface and a plane which is substantially parallel to the substantially planar surface and which includes a portion of the desired focal area. The shield element may include a reflective surface to reflect light received from the secondary mirror toward the desired focal area.

Abstract: Embodiments of the present invention control an atmosphere of a volume surrounding an energy conversion unit, such as a concentrator photovoltaic device. Differences between pressures within the volume and pressures outside the volume are controlled to reduce stress on seals and to prevent contaminants and moisture from flowing into the volume. A chamber for housing an energy conversion unit in accordance with one embodiment includes a housing and a controller. The housing defines a first unit volume for containing the energy conversion unit. The controller is coupled to the first unit volume and automatically controls an environment in the first unit volume. In one embodiment, the controller provides a flow path from a second unit volume outside the housing to a bladder within the first unit volume.

Abstract: Embodiments of the present invention seal an inside volume of an energy conversion unit from the outside atmosphere. A chamber for housing an energy conversion unit includes a lid having a first rim, a housing having a second rim, and a continuous seal sealing the first rim to the second rim. The lid and the housing form a volume with an atmosphere for securely housing an energy conversion unit. The seal has sidewalls that extend from the first rim to the second rim and includes an embedded ribbon that extends along a length of the seal such that the atmosphere is controlled by the continuous seal. Preferably, the embedded ribbon oscillates between the sidewalls in a pattern, such as a wave, a square wave, or a zig-zag. Preferably, the energy conversion unit is a concentrator photovoltaic device that includes optics for focusing light onto a photo-sensitive area of the photovoltaic device.
