Publication number: 20210153128Abstract: A wireless sensor node is described. The wireless sensor node may include a wake-up circuitry configured to awaken the sensor when a request is received. The sensor may be placed in a sleep mode, thus saving battery usage until a wake-up signal requesting use of the sensor is received. Powering of the wake-up circuitry may be supplied through energy captured using an energy harvester. In one example, the energy for powering the wake-up circuitry is extracted from the same signal used for awakening the sensor. The wireless sensor mode may operate in a passive mode, in which the energy for powering the wake-up circuitry is harvested, or in a power supply-assisted mode, in which some of the power is provided by a power supply. High quality factors filters may be used to increase the signal-to-noise ratio of the wake-up signals, thus improving the node's ability to recognize activation requests.Type: ApplicationFiled: January 26, 2021Publication date: May 20, 2021Applicant: Analog Devices GlobalInventors: Philip P.E. Quinlan, Paul Lambkin

Patent number: 10932220Abstract: Systems and methods permit automatic joining of a network associated with a specified area within which wireless nodes reside. Network managers located in or near the specified area use wireless proximity detection to estimate distances to wireless nodes requesting to join the network. The network managers can use the estimated distances to determine whether or not a requesting wireless node is located within the specified area. If the requesting wireless node is located within the specified area, the network managers can permit the wireless node to join the wireless network associated with the respective specified area.Type: GrantFiled: October 22, 2019Date of Patent: February 23, 2021Assignee: Analog Devices, Inc.Inventors: Tao Yu, Tze Lei Poo, Lance Doherty, Philip P.

Publication number: 20200288395Abstract: A system and method for monitoring components of a vehicle includes a manager and a wireless node. The manager is positioned on the vehicle and configured to wirelessly transmit a wake signal in response to an event. The wireless node positioned to monitor a component of the vehicle and includes an antenna, a wakeup circuit, and a node transceiver. The wakeup circuit is connected to the antenna and configured to monitor for the wake signal, and the node transceiver is configured to perform wireless communication with the manager. The wakeup circuit is configured to power on the node transceiver upon receipt of the wake signal.Type: ApplicationFiled: March 6, 2019Publication date: September 10, 2020Inventors: Lance Robert Doherty, Shane O'Mahony, Philip P.E. Quinlan, Mark Alan Lemkin

Patent number: 10129011Abstract: An apparatus comprising: a signal detection circuit determine a count reached by a counter between successive detected edge signals and to provide an indication of whether successive detected edge signals are separated from each other by at least a prescribed time interval; a clock circuit that produces clock signal pulses in response to a provided indication of an occurrence of a succession of detected edge signals each separated from a previous edge signal of the succession by at least the prescribed time interval; phase matching circuitry configured to align the produced clock signal pulses with detected edge signals; and a pattern matching circuit that that samples a sequence of detected edge signals aligned with the produced clock signal pulses to detect a data packet.Type: GrantFiled: May 25, 2017Date of Patent: November 13, 2018Assignee: Analog Devices GlobalInventors: Muhammad Kalimuddin Khan, Kenneth J.

Patent number: 9985608Abstract: Embodiments of the present disclosure provide a digital filter module for use in receivers, particularly suitable for use in a narrow-band electromagnetic receiver. Design of the module is based on a recognition that providing to the module samples of a signal received by a receiver and sampled at a sampling frequency equal to four times the intermediate frequency of the receiver, eliminating zeros in the filter, and implementing the filter module as a resource-shared second-order filter structure that includes two sections advantageously enables saving some hardware components, particularly some multipliers and adders, in implementing a versatile digital filter module that can function either as two real filters or one complex filter. In this manner, substantial reduction of area and power consumption of the filter module may be achieved, while maintaining sufficiently high filtering performance.Type: GrantFiled: September 24, 2015Date of Patent: May 29, 2018Assignee: ANALOG DEVICES GLOBALInventors: Sudarshan Onkar, Philip P.
