An air conditioning system including a conditioning unit (e.g., fan coil unit) and a control system are provided for efficiently and effectively conditioning indoor air. Some embodiments address temperature control (e.g., including heating and cooling), humidity control, and air quality control, while also introducing conditioned outdoor air. One aspect relates to a control system that delivers liquid to a coil in the conditioning unit at a specified input temperature and flow rate (or specified input temperature and temperature drop across the coil) to meet both sensible and latent cooling demands.

System and method for controlling indoor environments

A system and method are provided for performing a hole inspection performance study. Specimens for the performance study are made from a reconfigurable set of inspection plates. Each plate includes multiple test holes which are located symmetrically. The plates may be of various thicknesses and materials. Each test hole may or may not have a feature such as a crack or machining notch. Such features may be located at various positions of the hole, such as at an edge, within the bore, and at various circumferential positions. A specimen is formed by stacking two or more plates and securing the stack together with an alignment tool. A variety of specimens may be formed by using different combinations of inspection plates and flipping and rotating the member plates.

System and method for hole inspection and qualification

Disclosed are method and apparatus for measuring material properties. Segmented field sensors have multiple sensing elements at different spatial geometries to capture field components having substantially different depths of penetration. These sensors are excited and measured on these different sensing elements to facilitate characterization of unknown material properties. This is illustrated in some embodiments using eddy current sensors to characterize materials that are frequency dispersive and/or do not produce a measurable phase shifts. Only a single scalar quantity may provide independent information from one or more of the sensing elements. Property estimation techniques, such as those using precomputed databases of sensor responses are used to estimate the unknown material properties.

Segmented field eddy current sensing for dispersive property measurement and complex structures

A control system is provided for controlling heating and/or cooling with a conditioning load such as fan coils and chilled beams. Based on user input and ambient conditions, the control system determines a desired temperature for the liquid entering the load and combines fresh supply liquid (e.g., from a chiller or boiler) with a portion of the liquid that has passed through the load, to achieve the target load input temperature for the liquid. A recirculation pump may be used to return a portion of the liquid exiting the load for mixing with the fresh supply liquid and a control valve may be used to adjust the ratio of fresh supply liquid and recirculated liquid to achieve the targeted temperature. The control systems can be compatible with a variety of liquid supply systems such as two- and four-pipe systems.

System and apparatus for conditioning of indoor air

The present disclosure provides an image sensor panel (ISP) and a method for fabricating the image sensor panel (ISP). In one aspect, the method includes forming a well in an assembly, forming a bottom electrode in the well, forming a photosensitive layer in the well, and forming a top electrode over the photosensitive layer.

Image sensor panel and method for fabricating the same

In one aspect, the present disclosure provides an electronic device having a light source, a two-dimensional photosensor, the photosensor and the light source being stacked on top of each other, and a non-transitory computer readable memory. In one example, the mobile electronic device is configured to: capture two or more frames using the photosensor while light is emitted from the light source, identify common features in neighboring frames of said two or more frames, combine said two or more frames into an image based on the common features, such that the common features are spatially collocated in the image, and record the image to the memory.

System and method for constructing document image from snapshots taken by image sensor panel

In one aspect, the present disclosure provides a system and a method for constructing a document image from snapshots of portions of a subject document taken by a two-dimensional image sensor panel. In another aspect, the present disclosure provides a mobile electronic device comprising: an image sensor panel; a non-transitory computer readable memory; and a processor configured to: capture a sequence of frames from the image sensor panel, identify corresponding features in said sequence of frames, combine said sequence of frames into a resultant image such that the corresponding features are spatially collocated in the resultant image, and record the resultant image to the memory.

Methods and apparatus for characterizing composite materials for manufacturing quality assurance (QA), periodic inspection during the useful life, or for forensic analysis/material testing. System are provided that relate eddy-current sensor responses to the fiber layup of a composite structure, the presence of impact damage on a composite structure with or without a metal liner, volumetric stress within the composite, fiber tow density, and other NDE inspection requirements. Also provided are systems that determine electromagnetic material properties and material dimensions of composite materials from capacitive sensor inspection measurements. These properties are related to the presence of buried defects in non-conductive composite materials, moisture ingress, aging of the material due to service or environmental/thermal exposure, or changes in manufacturing quality.
