  • Publication number: 20250212119
    Abstract: Systems, methods, and devices provide low-power wakeup operations in wireless environments. Methods include receiving a signal at a wireless device, the signal comprising a data packet compatible with a wireless communication protocol, performing, using one or more processing elements, a first wake detection operation at a first wake stage of the wireless device, and determining, based on a designated pattern and performance parameters, if a second wake detection operation should be performed at a second wake stage of the wireless device. Methods also include determining, using one or more processing elements, if a valid wake code has been received based on a designated wake code associated with the data packet.

  • Publication number: 20240365237
    Abstract: Systems, methods, and devices provide low-power wakeup operations for wireless devices. Methods include receiving an audio signal from a first wireless device at a second wireless device via an audio transducer, the audio signal including a plurality of encoded data values, and determining, using a processing device of the second wireless device, if the received audio signal includes a valid wakeup code. Methods also include transitioning a transceiver of the second wireless device from a sleep mode to a wake mode in response to determining that the audio signal includes a valid wakeup signal.

  • Patent number: 9544027
    Abstract: A loop-powered transmitter includes a data isolation transformer including primary and secondary windings and an analog-to-digital converter (ADC) to convert a sensor signal to a digital value. The transmitter also includes a first microcontroller coupled between a multi-signal interface of the ADC and only one tap of the primary winding of the data isolation transformer, and a second microcontroller coupled to the secondary winding of the data isolation transformer. The first microcontroller is configured to receive the digital value from the ADC over the multi-signal interface and to provide data indicative of the digital value via a single output data line through the tap of the primary winding of the data isolation transformer to the second microcontroller. Unipolar voltage converters may also be included in the transmitter along with a current limiting resistor for the data isolation transformer to reduce the risk of saturating the data isolation transformer.

  • Publication number: 20100169517
    Abstract: A detection circuit indicates when a source device is coupled to a sink. An interface circuit separately interfaces with the plurality of source devices and permits display identification data associated with an interfaced source device to be sent from the memory unit to the interfaced source device. A monitoring unit monitors communications between the plurality of source devices and a memory unit and generates a signal for the plurality of source devices upon identifying that the memory unit is available for storing display identification data that is associated with a remaining source device of the plurality of source devices. The signal is communicated to the control unit to cause the control unit to update the memory unit with the display identification data that is associated with the remaining source device(s). A power detection circuit powers the sink via power from a source device(s) in a low-power mode.
