  • Patent number: 11693521
    Abstract: This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

  • Patent number: 11689089
    Abstract: Wireless power transmission (WPT) systems are provided. For example, the WPT system can use one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor.

  • Patent number: 11670935
    Abstract: A protection IC protects an external load connected to mains supply lines from dangerous or undesired conditions such as overvoltage, undervoltage, and overcurrent, by disconnecting the external load for at least the duration of such a condition. The IC has a range detector, a zero-crossing detector, a control unit, a switch driver, and a dummy DAC. The range detector senses the presence of an unwanted condition. The control unit then waits for a zero crossing, upon which it disconnects the load. A lockout timer may introduce a minimum wait time before reconnecting the load. To prevent instabilities around the switching points, hysteresis in the window thresholds prevents impact from noise. The dummy DAC regulates a dummy current that linearizes the IC's current consumption around the switching points to prevent instabilities caused by positive feedback in non-linear transitions.
