    摘要： Methods for forming a coating over a surface are disclosed. A method includes directing a first source of barrier film material toward a substrate in a first direction at an angle θ relative to the substrate, wherein θ is greater than about 0° and less than about 85°. Additionally, a method of depositing a barrier film over a substrate includes directing a plurality of N sources of barrier film material toward a substrate, each source being directed at an angle θN relative to the substrate, wherein for each θN, θ is greater than about 0° and less than about 180°. For at least a first of the θN, θN is greater than about 0° and less than about 85°, and for at least a second of the θN, θN is greater than about 95° and less than about 180°.

    摘要： Systems and methods disclosed herein provide for a passive backscattering beamformer based on large-area electronics (LAE). Low power is critical for distributed nodes in future IoT/5G networks. A key emerging solution is using ubiquitous 2.4 GHz Wi-Fi infrastructure with passive backscattering nodes, for low-power communication. LAE enables monolithic integration of devices over large and flexible substrates, with recent advances into the gigahertz regime opening new opportunities for wireless systems. An LAE passive backscattering beamformer is chosen that is capable of (1) enhancing the backscattered signal power in a scalable manner enabled by LAE's monolithic integrability over meter-scale area; (2) configuration between constructive/destructive beamforming; (3) frequency-shift keying for data modulation and SNR enhancement, by shifting the signal away from the incident interferer; and (4) frequency division multiplexing for increasing data bandwidth.

    摘要： A three dimensional touch sensing system having a touch surface configured to detect a touch input located above the touch surface is disclosed. The system includes a plurality of capacitive touch sensing electrodes disposed on the touch surface, each electrode having a baseline capacitance and a touch capacitance based on the touch input. An oscillating plane is disposed below the touch surface. A touch detector is configured to drive one of the touch sensing electrodes with an AC signal having a frequency that shifts from a baseline frequency to a touch frequency based on the change in electrode capacitance from the baseline capacitance to the touch capacitance. The touch detector is configured to drive the oscillating plane to the touch frequency.
