Abstract: A control system for independent alternating-input (“IAI”) devices includes multiple IAI devices and an analog switch component. The control system may also include a bus-generating component. The analog switch component includes multiple switches configured to connect of disconnect input connection points of the analog switch component and voltage input points of the IAI devices. The analog switch component opens or closes switches, responsive to a digital control signal, to provide voltage signals to the voltage input points of the IAI devices. In some cases, the IAI devices activate or deactivate based on the provided voltage signals. In some cases, the bus-generating component provides a first voltage signal to a first voltage input point of an IAI device, and the analog switch component controls the switches to provide a second voltage signal to a second voltage input point of the IAI device.

Abstract: The present disclosure relates to non-emissive modular light-diffuser devices that selectively revealing reflective material and that can be utilized in applications ranging from wearable electronics to large format displays. For example, by applying power, the modular light-diffuser devices can switch from a light-scattering state and a non-light-scattering state to reveal reflective material beneath. In particular, a modular light-diffuser device can utilize dual inputs to provide an alternating low-voltage current to a PDLC film layer (e.g., by rotating the direction of electrical polarity), thus, significantly extending the life of the modular light-diffuser device. In addition, multiple modular light-diffuser devices can be grouped and added to objects (e.g., clothing, fashion accessories, or large format displays) to form patterns, designs, and animations based on the modular light-diffuser devices changing states.

Abstract: The present disclosure includes systems, methods, computer readable media, and devices that can generate accurate augmented reality objects based on tracking a writing device in relation to a real-world surface. In particular, the systems and methods described herein can detect an initial location of a writing device, and further track movement of the writing device on a real-world surface based on one or more sensory inputs. For example, disclosed systems and methods can generate an augmented reality object based on pressure detected at a tip of a writing device, based on orientation of the writing device, based on motion detector elements of the writing device (e.g., reflective materials, emitters, or object tracking shapes), and/or optical sensors. The systems and methods further render augmented reality objects within an augmented reality environment that appear on the real-world surface based on tracking the movement of the writing device.

Abstract: The present disclosure includes systems, methods, computer readable media, and devices that can generate and present a digital overlay over a view of a tangible object within a display case. In particular, the systems and methods described herein can synchronize a switchable diffuser element with a display screen and one or more light sources to alternate between a scatter state and a transparent state based on a display rate. In particular, the disclosed systems and methods can alternate the display screen between an emissive state (for displaying an emitted digital image) and an attenuating state (for displaying a transparency mask image). By synchronously toggling the display screen and the diffuser element between states, the disclosed systems can present a digital overlay superimposed over a view the inside of the display case.

Abstract: Systems and techniques are disclosed that use an image capture device to capture images of an object under specified image capture conditions for use in determining reflectance properties of the object. Images of the object are captured from a variety of different camera directions and with the object illuminated from a variety of different light directions. To capture these images, a camera of the image capture device is moved relative to the object and lights of the device are selectively illuminated. The image capture device has various features that increase the variety and number of different image capture conditions that can be captured. For example, using planar arrays of individually addressable lights in the image capture device allows tens, hundreds, or even thousands of lights to be used. Using planar arrays of lights provides light from many different directions without adding substantial complexity or cost to the device.
