    Abstract: An electronic apparatus includes an electric motor, driver circuitry to drive the electric motor, a temperature sensor to detect a temperature of the electric motor, and one or more processors. The one or more processors control the driver circuitry to drive the electric motor according to a predetermined voltage signal to cause the electric motor to stall and generate heat, receive information about the temperature of the electric motor detected by the temperature sensor while the electric motor is stalled, and maintain a temperature of the electric motor below a threshold temperature value while the electric motor is stalled based on the information about the temperature of the electric motor detected by the temperature sensor while the electric motor is stalled.

    Abstract: Techniques, apparatuses, and systems are described for integrating haptic actuators into accessories for mobile computing device. Current accessory devices and their associated housings lack the necessary space to implement multiple haptic actuators for conveying complex haptic information. The accessory device attached to the mobile computing device provides additional space for integrating haptic actuators, which provide complex haptic information to a user of the mobile computing device. Using the haptic device accessory, the mobile computing device can convey haptic information to a user of the accessory device. In this way, a haptic device accessory can improve the otherwise limited haptic experience for a user of the accessory device.

    Abstract: The present disclosure provides computer-implemented methods, systems, and devices for capturing spatial sound for an environment. A computing system captures, using two or more microphones, audio data from an environment around a mobile device. The computing system analyzes the audio data to identify a plurality of sound sources in the environment around the mobile device based on the audio data. The computing system determines, based on characteristics of the audio data and data produced by one or more movement sensors, an estimated location for each respective sound source in the plurality of sound sources. The computing system generates a spatial sound recording of the audio data based, at least in part, on the estimated location of each respective sound source in the plurality of sound sources.

    Abstract: A vibrotactile device including a first actuator channel having a vibrotactile actuator and a resistor with a predetermined resistance positioned at an input of the vibrotactile actuator, a processor configured to output a driving signal for driving the vibrotactile actuator, and a voltage sensor configured to measure a voltage drop across the resistor. A current drawn by the vibrotactile actuator varies according to a load applied to the vibrotactile actuator and passes through the resistor. The processor is configured to receive voltage drop measurement data from the voltage sensor, detect a load applied to the vibrotactile actuator based on the measured voltage drop, and control the driving signal based on the detected load.

    Abstract: The present disclosure provides systems and methods for using a linear resonant actuator (“LRA”) to determine a type of contact between a device and its surroundings. The LRA may be coupled to an amplifier by one or more switches. The audio amplifier may receive a signal from a microcontroller and transmit the signal the LRA when the switches are closed. When the switches are in an open position, the LRA may be actively sensing for the type of contact. The back EMF may be measured when the switches are open. The measured back EMF waveform may be used to determine the type of contact. When the signal is not being transmitted, the LRA may be passively sensing to determine whether the device was tapped.
