  • Publication number: 20240151801
    Abstract: A method for modifying a repeat interval of a locator beacon is described. The method includes transmitting repeatedly, by a beacon transmitter, a first advertising beacon signal through a first number of transmission repetitions spaced at a first repeat interval. The method further includes transmitting repeatedly, by the beacon transmitter, a second advertising beacon signal through a second number of transmission repetitions at a second repeat interval, wherein the second advertising beacon signal includes an identifier that provides identification of the beacon transmitter and user information. The method further includes receiving a modification instruction from a user device. The modification instruction is configured to modify the first repeat interval into a third repeat interval. The method also includes transmitting repeatedly, by a beacon transmitter, the first beacon signal through the first number of transmission repetitions spaced at the third repeat interval.

  • Publication number: 20240136991
    Abstract: A pulse-shaping network configured for use in a radio frequency (rf) power amplifier system, the pulse-shaping network comprising: a coupled magnetic element comprising a first inductive element magnetically coupled to a second inductive element, the first inductive element comprising a first winding disposed about a first portion of a core, and the second inductive element comprising a second winding disposed about a second portion of a core, wherein the first and second inductive elements are electrically coupled to provide three output terminals of the coupled magnetic element.

  • Publication number: 20240137018
    Abstract: Described is a power transmission gate which includes a charge pump, an NMOS transistor, and a gate driver circuit configured to power (or bias or “drive”) a gate of the NMOS transistor. With this arrangement, a power transmission gate capable of achieving substantially the same resistance provided by prior art power transmission gates while having a footprint of just over one NMOS size unit is provided.

  • Publication number: 20240080004
    Abstract: Described are circuits and techniques to increase the efficiency of radio-frequency (rf) amplifiers including rf power amplifiers (PAs) through “supply modulation” (also referred to as “drain modulation” or “collector modulation”), in which supply voltages provided to rf amplifiers is adjusted dynamically (“modulated”) over time depending upon the rf signal being synthesized. For the largest efficiency improvements, a supply voltage can be adjusted among discrete voltage levels or continuously on a short time scale. The supply voltages (or voltage levels) provided to an rf amplifier may also be adapted to accommodate longer-term changes in desired rf envelope such as associated with adapting transmitter output strength to minimize errors in data transfer, for rf “traffic” variations.

  • Publication number: 20220264667
    Abstract: Systems and methods for establishing a wireless connection using a connection identifier. The systems include a dust extractor and a power tool. The dust extractor includes an extractor electronic processor. The power tool includes a tool electronic processor. The extractor electronic processor is configured to: broadcast a connection advertisement; establish the wireless connection with a power tool when the connection advertisement is received; receive a request for the connection identifier; and provide a response including the connection identifier; provide a first indication of a successful wireless connection.
