Patent number: 10353511Abstract: The present disclosure describes aspects of a capacitance-to-voltage modulation circuit. In some aspects, the circuit is used in touch sensing. In some aspects, a modulation circuit comprises a first pair of switches having one switch connected between a voltage source and a capacitor, and another switch connected between ground and the input of the circuit. The circuit also includes a second pair of switches having one switch connected between the voltage source and the input of the circuit, and another switch connected between ground and the capacitor. A third pair of the circuit's switches comprise one switch connected between the capacitor and an input of an analog-to-digital converter (ADC) and another switch connected between the input of the circuit and the input of the ADC. The third pair of switches may enable charge sharing of signals modulated by the first and second pairs of switches, a result of which can be used to sense touch input based on capacitance at the input of the circuit.Type: GrantFiled: September 20, 2016Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: Bo-Ren Wang, Lennart Mathe, Sameer Wadhwa, Nathan Altman, Sandeep D'Souza

Patent number: 9897682Abstract: A synchronization system for an acoustic signal-based positioning system is provided that generates a magnetic field as a synchronization signal. The magnetic synchronization signal is transmitted by a transmitter of the positioning system and received by the receiver of the positioning system. The receiver may include a magnetic synchronization signal receiver that may receive the magnetic synchronization signal on a same acoustic channel as an acoustic positioning signal. Moreover, the magnetic synchronization signal receiver may be a component already present in the receiver and capable of receiving a magnetic synchronization signal.Type: GrantFiled: March 28, 2014Date of Patent: February 20, 2018Assignee: QUALCOMM IncorporatedInventors: Nathan Altman, Noam Z.

Patent number: 9741244Abstract: A control device executing a networking framework for controlling a network of smart objects registered with a framework may interact with only those smart objects in a room. A radio frequency signal broadcast on the networking framework for reception by smart objects registered with the networking framework may cause each of the plurality of smart objects to transmit an ultrasound signal that may include an identifier, such as a generic identifier of the smart object that was assigned during registration with the network framework. The control device may receive the ultrasound signals only from the smart objects in the room. The control device may rename each smart object from which ultrasound signals were received with new identifying information that may include a reference to the room. The device may then communicate with the smart objects via the networking framework using the new identifying information.Type: GrantFiled: May 11, 2015Date of Patent: August 22, 2017Assignee: QUALCOMM IncorporatedInventors: Gabriel Berelejis, Nathan Altman, Gilad Bornstein, Joshua Hershberg, Wayne Fenton
