Apr 14, 2020

Appl. No.:

16/848627

Inventors:

- Morris Plains NJ, US
Christian Kenneth Larson - Minneapolis MN, US
Robert Charles Becker - Eden Prairie MN, US

International Classification:

H04B 1/16
H03F 3/19
H01Q 1/50
H03F 3/217

Abstract:

A circuit and computer implemented method tunes an RF switching power amplifier circuit for an antenna by receiving a measurement of reflected RF signal from the antenna, receiving a measurement of current provided to the circuit from a power source, receiving a measurement of RF power provided to the antenna, adjusting a tunable antenna circuit responsive to the measurement of reflected RF signal, and adjusting a first capacitor capacitance value and a second capacitor capacitance value of a waveform shaping circuit in response to the received measurement of current and RF power.

International Classification:

G08B 21/02

Abstract:

Methods, devices, and systems for detecting incapacitation and location using nodes are described herein. One system for detecting incapacitation and location using nodes can include an impact sensor, and a node including a memory and a processor to execute executable instructions stored in the memory to determine an incapacitating event has occurred via the impact sensor, determine a location of the node using a plurality of nodes, where the plurality of nodes include the node, and transmit the incapacitating event and the location of the node to an external server.

International Classification:

G01S 5/14
G01C 21/34
G01S 5/04
G01S 5/08
G01C 21/28

Abstract:

A location system includes multiple master nodes located at corners of a coverage area. At least two master nodes are located on one edge of the coverage area and receive signals from a slave node within the coverage area. The at least two master nodes calculate a distance to the slave node and a location of the slave node within the coverage area.
