Force sensing based on structure-borne sound propagation
ForcePhone is a novel system for enabling phones to recognize the force applied to their touchscreen and/or body. ForcePhone uses built-in sensors to measure the applied force via a physical property called structure-borne sound propagation. The phone plays an inaudible sound through the phone's speaker. When the phone is free to vibrate, the sound from the speaker easily travels through its body to the phone's microphone. When a force is applied to the phone, vibration is restricted and the sound traveling through the pathway is degraded. ForcePhone estimate the amount of applied force by monitoring the change in sound degradation. |

Method and apparatus for client to content appliance (CA) synchronization
A new approach is proposed that contemplates systems and methods to support file synchronization between a local host and a cloud storage via one or more local content appliances (CAs), wherein each content appliance is a storage device/host configured to locally maintain documents and files previously downloaded from the cloud storage. First, a client agent at the local host discovers and connects to the CA that manage its files locally. To access a file/document that is not cached on its local host, the client agent requests and receives the file from the CA instead of downloading it directly from the cloud storage. When parts of the file are updated locally by the client, the client agent is configured to transmit the updated file to the CA, wherein the updated file is considered as having been fully committed from the client's perspective. The CA then synchronizes with and uploads the revised file to the cloud storage and/or other CAs in the background. |

A plasma processing method according to an aspect includes: preparing a plasma processing apparatus including: a chamber; a lower electrode; an upper electrode; a focus ring surrounding a peripheral edge of the lower electrode; and an annular coil disposed on an upper portion of the upper electrode at a more outer position than the peripheral edge of the lower electrode; placing a substrate on the lower electrode, with a peripheral edge of the substrate surrounded by the focus ring; introducing process gas into the chamber; generating plasma of the process gas by applying high-frequency power across the upper electrode and the lower electrode; and leveling an interface of a plasma sheath on an upper portion of the substrate with that on an upper portion of the focus ring by generating a magnetic field by supplying a current to the annular coil. |

Insulated semiconductor faceplate designs
An exemplary faceplate may include a conductive plate defining a plurality of apertures. The faceplate may additionally include a plurality of inserts, and each one of the plurality of inserts may be disposed within one of the plurality of apertures. Each insert may define at least one channel through the insert to provide a flow path through the faceplate. |
