The donor lists are distributed to the respective RNs. An access point is selected by each of the RNs from their respective donor lists to use as a sync signal source. Each of the RNs synchronize their respective clocks in phase and frequency using wireless sync signals received from the respective selected access points.

Abstract: A wireless access point serves dynamic direction-of-arrival reception. An access point radio wirelessly receives a wireless signal that transports time-domain data. Access point circuitry determines uplink utilization for the access point radio. The circuitry transforms the time-domain data into frequency-domain data. The circuitry filters the frequency-domain data for one direction-of-arrival responsive to the uplink utilization. The circuitry synthesizes the time-domain data from the filtered frequency-domain data. The radio wirelessly receives another wireless signal that transports additional time-domain data. The circuitry determines a higher uplink utilization for the access point radio. The circuitry transforms the additional time-domain data into additional frequency-domain data. The circuitry filters the additional frequency-domain data for multiple directions-of-arrival responsive to the higher uplink utilization.

Abstract: A liquid level sensor includes a base member disposed above the liquid. A lever arm is pivotally attached to the base member. The lever arm is configured to interact with the liquid so that it has an angular displacement relative to the base member. The angular displacement is a function of the level of the liquid in the liquid channel. A sensor senses angular displacement of the lever arm. A communications circuit transmits the angular displacement of the lever arm to a remote location. In a method of detecting a liquid level, a float that is buoyant in the liquid is placed into the liquid and is coupled to a lever arm. An angular displacement of the lever arm relative to a base member is measured. The liquid level is a function of the angular displacement of the lever arm.
