Grounding Design to Prevent Electrostatic Accumulation in Foldable Displays

In traditional polymer organic light emitting diode (P-OLED) displays, electrostatic charge buildup can occur near the edge of the display, leading to abnormalities such as green flashes, vertical crosstalk, or a greenish display. To mitigate this problem, a discharge path is established to release electrostatic charges by using silver dotting on the edge of the display that connects to a conductive black matrix and provides a grounding path. However, for foldable displays, the silver dotting can crack due to the movement and sliding of different layers as the device is folded and unfolded, causing disconnection from ground. This disclosure describes a foldable display that implements an electrostatic discharge path as a grounding mechanism to avoid electrostatic charge accumulation at the edge of the display. The grounding design includes silver printing on the trim area of the device that is linked to a conductive pressure sensitive adhesive (PSA) to release the electrostatic charge via the device enclosure

JiTS: Just-in-Time Scheduling for Real-Time Sensor Data Dissemination

We consider the problem of real-time data dissemination in wireless sensor networks, in which data are associated with deadlines and it is desired for data to reach the sink(s) by their deadlines. To this end, existing real-time data dissemination work have developed packet scheduling schemes that prioritize packets according to their deadlines. In this paper, we first demonstrate that not only the scheduling discipline but also the routing protocol has a significant impact on the success of real-time sensor data dissemination. We show that the shortest path routing using the minimum number of hops leads to considerably better performance than Geographical Forwarding, which has often been used in existing real-time data dissemination work. We also observe that packet prioritization by itself is not enough for real-time data dissemination, since many high priority packets may simultaneously contend for network resources, deteriorating the network performance. Instead, real-time packets could be judiciously delayed to avoid severe contention as long as their deadlines can be met. Based on this observation, we propose a Just-in-Time Scheduling (JiTS) algorithm for scheduling data transmissions to alleviate the shortcomings of the existing solutions. We explore several policies for non-uniformly delaying data at different intermediate nodes to account for the higher expected contention as the packet gets closer to the sink(s). By an extensive simulation study, we demonstrate that JiTS can significantly improve the deadline miss ratio and packet drop ratio compared to existing approaches in various situations. Notably, JiTS improves the performance requiring neither lower layer support nor synchronization among the sensor nodes

Impending Disruption: The Effect of E-commerce on the Future of Grocery Retail

The rise of the Internet and E-commerce fundamentally changed society and disrupted all industries. Over the past 30 years traditional retail has struggled to adapt to the new distribution channels. Most retailers could not meet customers rising expectations and beat out competition without shrinking margins. Thus, traditional retail has been plagued by bankruptcies, consolidation, and store closings. Other sectors of retail, notably the grocery sector, are in earlier days of transformation. Today, grocery retailers face similar trends, competitive pressures, and evolving consumer behaviors as the overall retail industry. Through observing and analyzing past and current trends in the space, I predict a large future growth of grocery e-commerce. Consequently, three other fundamental changes will follow: omni-channel distribution, consolidation, and a different physical grocery store.Business Administratio
