Abstract: Examples of augmented reality (AR) environment control advantageously employ multi-factor intention determination and include: performing a multi-factor intention determination for summoning a control object (e.g., a menu, a keyboard, or an input panel) using a set of indications in an AR environment, the set of indications comprising a plurality of indications (e.g., two or more of a palm-facing gesture, an eye gaze, a head gaze, and a finger position simultaneously); and based on at least the set of indications indicating a summoning request by a user, displaying the control object in a position proximate to the user in the AR environment (e.g., docked to a hand of the user). Some examples continue displaying the control object while at least one indication remains, and continue displaying the control object during a timer period if one of the indications is lost.

Abstract: Representative implementations of devices and techniques provide an exemplary system and method for detection and surveillance of an infectious agent, and particularly an agent that is spread through respiratory aerosols. In an embodiment, the system and method include retrieving a face covering that contains oral and/or nasal, and/or skin secretions and/or skin flora on or within a material of the face covering, removing one or more samples of the material of the face covering that contains the secretions from the face covering, and depositing the one or more samples into a predetermined formulation.

Abstract: In some implementations, an insect trap includes a plurality of individual cells, with each of the cells being configured to trap very few, and in some instances a single flying insect. Each cell defines a cavity and may be provided with an independently operable door to selectively close the cavity. One or more sensors may sense the presence of an insect to be trapped.

Abstract: An LED screen for use in interactive golf driving ranges is disclosed. In an embodiment, a system includes a plurality of enclosures each housing LED nodes, where the plurality of enclosures is arranged in a plurality of rows to form an LED screen. The system also includes a coupler configured to couple a first one of the plurality of enclosures to a second one of the plurality of enclosures. The system also includes an LED processor configured to control each of the nodes via the coupler to display media on the LED screen.
