Abstract: Apparatus and methods for determining information about one or more objects in a 3-dimensional (3D) space are disclosed. One aspect of the method includes defining a virtual ground plane within a monitored 3D space. The virtual ground plane is divided into a plurality of bins. Each bin has corresponding counter value. An object is detected in a respective image captured by each of a plurality of sensors. A respective line segment is selected corresponding to a respective light between each of the plurality of image sensors and the detected object. One or more bins of the virtual ground plane are selected onto which a respective projected line segment of each respective line segment overlap. Each counter value for each of the one or more selected bins is increased. A location of the object is determined based on a bin of the one or more bins having a highest counter value.

Abstract: Techniques for distinguishing objects (e.g., an individual or an individual pushing a shopping cart) are disclosed. An object is detected in images of a scene. A height map is generated from the images, and the object is represented as height values in the height map. Based on height properties associated with another object, it is determined whether the other object is associated with the object. If so determined, the objects are classified separately.

Abstract: Development of a flexible battery based on periodate/iodate-zinc system is disclosed. H3PO4—KCl dual quasi-solid electrolytes separated by an anion-exchange-membrane maintain the desired pH in electrodes and block unwanted ion movements. Poly(acrylic acid) fortifies the electrodes, enhances electrode flexibility, and avoids the free-flow of liquids. The NaMnIO6 shows a specific capacity of 650 mAg?1, approximately 81% of its theoretical capacity even when cells are bent. The overall technology is scalable by printing methods.

Abstract: The development of a novel battery comprising of high-oxidation-state periodate complex cathode and zinc anode is disclosed. A periodate complex H7Fe4(IO4)3O8 was prepared by a precipitation reaction between Fe(NO3)3 and NaIO4, and was used in battery development for the first time. NaMnIO6 double periodate salts were also synthesized from MnSO4 and NaIO4 using the same techniques. The H7Fe4(IO4)3O8 alone showed specific capacity of 300 mAh g?1; while NaMnIO6 showed specific capacity as high as 750 mAh g?1. Compared to single-electron processes in conventional cathode reactions, the possibility to significantly enhance cathode specific capacity via a multi-electron process associated with valence change from I(VII) to I2 is demonstrated. Novel 3D-printed reserve battery casing designs comprising replaceable electrodes also disclosed. Batteries featuring an ion-exchange membrane dual-electrolyte design are disclosed. Periodate based dry cell batteries utilizing polymer electrolytes are also disclosed.

Abstract: Disclosed herein are systems and methods for calibrating a stereoscopic imaging device. An example implementation includes receiving, at a processor, a plurality of image pairs from the stereoscopic imaging device and calculating, for each image pair in the plurality of image pairs, a respective row delta value indicative of a deviation along a horizontal axis between the first image captured by the first sensor and the second image captured by the second sensor. The implementation further includes determining a median row delta value based on each respective row delta value and subsequently a set of respective disparities in one or more features in the first image and the second image based on the median row delta value. The method further includes calculating a column delta value and calibrating the stereoscopic imaging device using the median row delta value and the column delta value.
