Abstract: A micro light-emitting diode (LED) display assembly includes a backplane, a passivation layer on the backplane, a micro LED on the passivation layer, and a non-transparent metal housing on the passivation layer, wherein the housing includes a base portion on the passivation layer, a sidewall portion upwardly extending from the base portion, a cap portion connected at a top of the sidewall portion, an orifice in the cap portion, and a notch in the cap portion and adjacent to the orifice. The assembly also includes a translucent filter positioned in the notch and covering the orifice, and a pocket defined by an enclosed area in between the sidewall portion, the cap portion, the filter, and the passivation layer, wherein the micro LED is encased within the pocket such that light transmitted from the micro LED directly hits and passes through the filter.

Abstract: Examples associated with user authentication are described. One example method includes authenticating a user of a device using a static authentication technique. A behavior profile associated with the user is loaded. The behavior profile describes a pattern of device usage behavior by the user in a three-dimensional space over a time slice. The behavior profile also identifies distinctive user habits. Usage of the device is monitored, and a behavior similarity index is periodically updated. The behavior similarity index describes a similarity between the usage of the device and the pattern of device usage behavior. The behavior similarity index is weighted based on the distinctive user habits. Access to the device is restricted when the behavior similarity index reaches a predefined threshold.

Abstract: A gas conduit directs a flow of gas from a gas flow source. A surface enhanced luminescence (SEL) stage is within the conduit and includes a substrate and nano fingers projecting from the substrate. A heater heats the nano fingers to a temperature so as to soften the nano fingers such that the nano fingers collapse towards each other to capture molecules entrained in the gas therebetween.

Abstract: Example implementations relate to flexible displays. For example, a flexible display system may comprise a plurality of display layers, an anti-reflective layer among the plurality of display layers to reduce reflection from an underlying light emitting layer, the anti-reflective layer including a wave plate and a polarizer, and a transistor layer among the plurality of display layers. Further, at least a portion of the plurality of display layers may include properties satisfying particular geometric and force balance constraints to enable the transistor layer to maintain a neutral force in response to compression or tension of the flexible display.

Abstract: An RFID security device for product packaging is disclosed. The security device includes an RFID tag disposed on a first portion of a product package, and a booster antenna disposed on a second portion of the product package. The RFID tag and booster antenna are positioned on the product package so that the RFID tag will be electromagnetically coupled to the booster antenna when the product package is closed, and the RFID tag will be decoupled from the booster antenna when the product package is open.

Abstract: In an example, an air filter system includes an air filter and a thermally conductive particulate sensor (TCPS). The TCPS includes a temperature sensor to measure a first temperature of the TCPS at a first time, measure a second temperature of the TCPS at a second time, and provide the measured first temperature and the measured second temperature to a controller. The controller to determine an actual rate of temperature change based on the measured first temperature and the measured second temperature, compare the actual rate of temperature change to a target rate of temperature change, and provide a notification when a difference between the actual rate of temperature change and the target rate of temperature change is greater than an accumulation threshold indicative of a threshold amount of particulate accumulation on the TCPS.
