  • Publication number: 20210085237
    Abstract: Disclosed is a sensor that includes a first textile assembly having a first conductive textile element and a first outer sheath that surrounds the first conductive textile element. The first outer sheath is formed from a first non-conductive material that is configured to transport moisture through the first outer sheath. The sensor includes a second textile assembly having a second conductive textile element and a second outer sheath that surrounds the second conductive textile element. The second outer sheath is formed from a second non-conductive material that is configured to transport moisture through the second outer sheath. The first and second outer sheaths are in contact with each other so as to maintain separation between the first conductive textile element and the second conductive textile element along a length of the sensor.

  • Patent number: 10833694
    Abstract: In accordance with some embodiments, polarity-coincidence, adaptive time-delay estimation (PCC-ATDE), mixed-signal techniques are provided. In some embodiments, these techniques use 1-bit quantized signals and negative-feedback architectures to directly determine a time-delay between signals at analog inputs and convert the time-delay to a digital number.

  • Patent number: 8730048
    Abstract: Design and operation techniques for an earphone-based game controller and health monitor are described herein. In one example, two “ear bud” style earphones are configured as I/O devices, each including a speaker to output sound and an accelerometer to receive an input of motion imparted by a user. The I/O devices may be connected to a mobile device, such as a cellular phone. Accordingly, the I/O devices may be inserted into a user's ears for listening or may be used as game controllers, such as by moving one I/O device in each hand. In a further example, a thermometer may be used in at least one of the I/O devices, and may gather health data by measuring the temperature of the user. And in a further example, a microphone may be used in at least one I/O device to gather heart rate and respiration-quality data regarding the user.

  • Publication number: 20130073681
    Abstract: Some implementations disclosed herein provide techniques and arrangements to enable interactive zones. For example, some implementations detect that a user has entered a zone associated with a physical object, where the zone is created via magnetic induction. In response to detecting that the user has entered the zone, some implementations send a virtual object representation of the physical object to a user device (e.g., a wireless phone) associated with the user. The user may interact with the virtual object, including selecting a command associated with the virtual object. Selecting the command may cause the physical object to perform one or more actions. In some implementations, a result of the physical object performing the one or more actions is sent to the user device.
