Abstract: People use their mobile devices anywhere and anytime to run various apps, and the information shown on their device screens can be seen by nearby unauthorized parties, referred to as shoulder surfers. To mitigate this privacy threat, techniques have been developed utilizing human vision and optical system properties to hide the users' on-screen information from the shoulder surfers. Specifically, the proposed techniques discretize the device screen into grid patterns to neutralize the low-frequency components so that the on-screen information will “blend into” the background when viewed from the outside of the designed visible range.

Abstract: The current disclosure describes techniques for forming a gate-all-around device where semiconductor layers are released by etching out the buffer layers that are vertically stacked between semiconductor layers in an alternating manner. The buffer layers stacked at different vertical levels include different material compositions, which bring about different etch rates with respect to an etchant that is used to remove at least partially the buffer layers to release the semiconductor layers.

Abstract: An in-car phone localization scheme is proposed to determine, in real time, the locations of smartphones inside a moving car, with the goal of preventing smartphone-distracted driving. The localization system operates on commodity smartphones, and does not require any additional special/customized sensors or devices to be installed inside the car, making its deployment easy and attractive to users and carmakers. Even when a phone is moved from one location to another inside a moving car, the system will detect this movement, record the sensor data, and estimate the phone's destination location. The system captures the trajectory of each phone movement, the change of magnetic field, and the RSSI readings from the car Bluetooth transceiver, and then estimates the phone's destination location by matching the trajectory with the variation of magnetic field and the Bluetooth RSSI readings.

Abstract: A drill structure comprises a shank part and a bit part. A web is formed on the front end of the bit part. Two sides of the web are tilted backward to form two cutting faces. At least one chip-discharge groove is formed on the surface of the bit part. Each cutting face includes a primary cutting face and a secondary cutting face. The thickness of the prismatic web edge of at least one primary cutting face is smaller than the outer-side width of the primary cutting face. An auxiliary cutting face is extended to the wall of the flute from the cutting edge of the primary cutting face and a portion of a blade back of the secondary cutting face of another cutting face. The present invention decreases the drilling resistance during drilling a hole and increases the service life of the drill bit.
