Patent number: 10942550Abstract: The present invention includes provides secure, instant, and anonymous connections between two devices. The invention pairs a “cap” device with a capacitive touchscreen to a “cam” device with a camera sensor. For example, typical smartphones and tablets can be paired with each other, and these devices can be paired to even larger touchscreens, such as smart whiteboards and touchscreen monitors. The invention uses the cap device's touchscreen to detect and track the cam device, and displays color-modulated pairing data directly underneath the camera once the camera is touching the screen. The pairing data is used as configuration data for a bidirectional link, such as an ad-hoc WiFi or Bluetooth link. These links are established without requiring user configuration. As such, the present invention provides a unidirectional communication mechanism from the touchscreen to the camera, which is used to bootstrap a full bidirectional, high-speed link.Type: GrantFiled: April 20, 2017Date of Patent: March 9, 2021Assignee: CARNEGIE MELLON UNIVERSITYInventors: Bo Robert Xiao, Christopher Harrison, Scott E.

Patent number: 10942603Abstract: Techniques that can improve efficiency of a touch sensitive device are presented. A touch controller (TC) can comprise a hover classification engine and an application processor (AP) can comprise a touch classification engine usable to classify touch or hover interactions of an object(s) with a touch sensitive surface (TSS) of the device. In response to classifying a touch or hover interaction with TSS as unintentional, AP can reject such interaction and can transition from an active state to an inactive state. TC can continue to monitor touch or hover interactions with TSS. In response to determining there is an intentional touch interaction with TS S or no unintentional face/ear interaction with TSS, TC can transmit a notification signal to AP. In response to the notification signal, AP can transition from the inactive state to active state, and can process the intentional touch interaction or monitor the TSS.Type: GrantFiled: May 6, 2019Date of Patent: March 9, 2021Assignee: QEEXO, CO.Inventors: Joshua Dale Stone, Yanfei Chen, Shyama Purnima Dorbala, Bo Robert Xiao

Patent number: 10436615Abstract: A sensing system includes a sensor assembly that is communicably connected to a computer system, such as a server or a cloud computing system. The sensor assembly includes a plurality of sensors that sense a variety of different physical phenomena. The sensor assembly featurizes the raw sensor data and transmits the featurized data to the computer system. Through machine learning, the computer system then trains a classifier to serve as a virtual sensor for an event that is correlated to the data from one or more sensor streams within the featurized sensor data. The virtual sensor can then subscribe to the relevant sensor feeds from the sensor assembly and monitor for subsequent occurrences of the event. Higher order virtual sensors can receive the outputs from lower order virtual sensors to infer nonbinary details about the environment in which the sensor assemblies are located.Type: GrantFiled: April 24, 2018Date of Patent: October 8, 2019Assignee: Carnegie Mellon UniversityInventors: Yuvraj Agarwal, Christopher Harrison, Gierad Laput, Sudershan Boovaraghavan, Chen Chen, Abhijit Hota, Bo Robert Xiao, Yang Zhang
