  • Patent number: 10825855
    Abstract: Bending a flexible x-ray detector to image a curved structure or object will distort the object appearance when compared to an image captured by a flat/rigid detector. An image distortion of this type can be corrected when the shape (relative bend position) of the x-ray detector is known. Incorporating strain sensors on the flexible x-ray detector makes it possible to record the local bend of the flexible x-ray detector when an image is taken. This shape information can be used to either label or correct for the image distortions created by bending the x-ray detector to assist users more accustomed to viewing images produced by flat/rigid x-ray detectors.

  • Patent number: 10603505
    Abstract: An implantable neural probe includes a flexible substrate having a first surface and an opposing second surface. The probe has an elongated three dimensional shape with an exterior surface and an interior surface such that the exterior surface of the probe includes at least a portion of first surface of the flexible substrate and the interior surface of the probe includes at least a portion of the second surface of the flexible substrate. The probe may include an array of one or more neural stimulators disposed on the flexible substrate and configured to stimulate neurons. The probe may alternatively or additionally include an array of one or more neural sensors configured to sense brain neurons.

  • Patent number: 10608041
    Abstract: Transitioning conventional x-ray detector materials and structures to bendable or flexible (e.g., plastic) substrates makes them rugged against breakage when dropped but exposes the detectors to damage if bent. Disclosed are bendable digital x-ray detector structures that are rugged with regard to bending as well as dropping. The structures provide strain matching between layers so that a detector backplane is in and/or near the mechanical neutral plane and therefore less susceptible to bending stress.

  • Patent number: 10589248
    Abstract: One embodiment provides a chemical reactor, which can comprise a substrate for facilitating chemical reactions occurring at triple-phase boundaries. One possible substrate may further comprise a set of dynamically controllable sites and/or pixels upon which control signals may affect a desired formation of gas bubbles over an active catalytic (or other desired) solid surface in a liquid flow—wherein a chemical reaction in two or more phase boundaries may occur. In yet another embodiment, a control algorithm may send control signals to controllable sites/pixels to maximize the operation of the reactor according to a desired metric (e.g., product formation) that may input a set of sensor data to affect its control.
