The hose may be associated with means for providing a magnetic field through which the fuel, in use, is led.

A current is supplied to selected juxtaposed pairs of the coils (142) so as to set up a magnetic field.

A radio frequency antenna (12) produces the time varying magnetic field used for powering the sensor, as well as receiving the magnetic field response of the sensor.

In the Distant CRM object, select the element you will feed into Zendesk.

The magnetic field may inductively couple and power the rings, which may each contain an LC tank circuit.

The AC signal is applied to the tank circuit (120) to create an inductive field for powering the secondary..The secondary communicates feedback about the received power back to the primary controller (110).

The external base station can provide a passive electric field to power the implant, or to charge its battery.

A power supply (160) is configured to power the wireless field device.

An exciter (16) is configured to energize the DC field winding (13) by generating a DC current in a first direction across the DC field winding (13) when activated.

Allicin powder is applied to feed additive field. […]

A battery contained within the housing is connected to the electronic circuit to power the generation and transmission of the electromagnetic field.

The sensor is responsive to a magnetic field to displace piezo-electric material to thereby generate electricity to power the device.

The data fields include an identifier field (30), name field (34), value field (36), signature field (32), classes field (38), children field (40), versions field (42), user ID field (44), date field (46), and control flag field (48).

The transponder uses a coil (202) to derive both power and a clock pulse from the high-intensity field for powering and driving an identification circuit.

An inductive power pick-up 120 is associated with a sensor 124 and is capable of receiving power from the field to supply the sensor 124.
