Flexible lens sheets could change way cameras see

Engadget

In order to create a wraparound camera, the team first considered attaching tiny lenses to single pixel-sized sensors, a tact that's been tried before on curved surfaces. However, they realized that when bent, such an array would have gaps between sensors that would produce artifacts in the final image. Instead, they created flexible silicon sheets with embedded lenses that distort and change their focal lengths when bent. The resulting prototype has no blank spots, even with significant curvature, so it can capture images with no aliasing. The team flexed the prototype sheet -- with a 33x33 lens array -- in a predictable way, allowing them to produce clean (though low resolution) images.


Samsung Galaxy X Flexible Phone: Specs, Features And Expected Release Date

International Business Times

And since then there have been speculation and anticipation about the company releasing a flexible display phone. The company might finally come out with one this year -- the Samsung Galaxy X rumors started buzzing early this month after the company filed a patent describing a foldable display with a mechanical hinge in the middle. Foldable Display: The most anticipated feature of the Samsung Galaxy X is of course, its display. It is expected to fold inwards, with a mechanical hinge in the middle that will also serve as a display. When stretched out, according to the company's patent filed on Jan.


On Training Flexible Robots using Deep Reinforcement Learning

arXiv.org Artificial Intelligence

The use of robotics in controlled environments has flourished over the last several decades and training robots to perform tasks using control strategies developed from dynamical models of their hardware have proven very effective. However, in many real-world settings, the uncertainties of the environment, the safety requirements and generalized capabilities that are expected of robots make rigid industrial robots unsuitable. This created great research interest into developing control strategies for flexible robot hardware for which building dynamical models are challenging. In this paper, inspired by the success of deep reinforcement learning (DRL) in other areas, we systematically study the efficacy of policy search methods using DRL in training flexible robots. Our results indicate that DRL is successfully able to learn efficient and robust policies for complex tasks at various degrees of flexibility. We also note that DRL using Deep Deterministic Policy Gradients can be sensitive to the choice of sensors and adding more informative sensors does not necessarily make the task easier to learn.


Samsung Gear S4 Smartwatch Could Have Flexible Battery In Straps

International Business Times

Samsung is expected to revamp its Gear S smartwatch series later this year. However, details on its Gear S4 installment surfaced online as early as this week. The South Korean brand has apparently filed new patents that seem to suggest the type of technologies it is preparing for its upcoming wearable.
