  • Publication number: 20250234155
    Abstract: Methods and systems are disclosed relating to proximity detection of devices and targeted information services, such as information campaigns. Disclosed methods provide targeted campaigns to a user, such as targeted campaigns to presentation devices based on proximity of user devices near the information devices. Other methods provide targeted campaigns across various applications, while other methods provide for scheduling campaigns to premises device identifiers based on an event schedule, and other methods provide a hierarchal system for monitoring different sets of premises device identifiers when a user device can monitor for a limited number of premises device identifiers at a time.

  • Publication number: 20250099823
    Abstract: A golf club head including a face defining a loft plane, a rear, and a crown, the crown having a turbulator comprising a plurality of ridges. Each ridge includes a front surface having a first end nearest the face, a second end nearest the ridge apex, and a rear surface nearest the rear portion of the club head. The turbulator is positioned in a forward two-fifths portion of the crown in a front end to a rear end direction. The ridge apex of each ridge is positioned within the first 50% of the ridge length.

  • Patent number: 12241824
    Abstract: A soot sensing system includes a soot sensor having a first element, and circuitry to an amount of soot accumulated on the element and to control heating of the element in response to the soot accumulation. An electrostatic repelling voltage (ERV) may be applied to a sensor/heater element(s) during a contamination prevention mode (CPM) to repel ash and reduce contamination of the sensor. A pulsed heating voltage (PHV) may be applied to the elements during the CPM and a pulsed ERV may be applied to the elements during the “off” period of the PHV. All voltage to the elements may be turned off during the CPM and the elements may be floating/ground. A PHV may be applied to the elements during the CPM and no voltage may be applied to the elements during the “off” period of the PHV. A heating voltage may be applied to the elements during a CPM corresponding to a cold start.
