Improved Formulae for the Inductance of Straight Wires
The best analytical formulae for the self-inductance of rectangular coils of circular cross section available in the literature were derived from formulae for the partial inductance of straight wires, which, in turn, are based on the well-known formula for the mutual inductance of parallel current…
Las Vegas hotel chooses LEGIC Connect for room keys
Opening hotel rooms with smartphones became reality in Las Vegas. The Cromwell Las Vegas decided to use the combination of the LEGIC Connect trusted service, Kaba Mobile Access Solutions and Bluetooth Low Energy, allowing the hotel to send keys onto smartphones with the touch of a button.
The GMD Method for Inductance Calculation Applied to Conductors with Skin Effect
The GMD method (geometric mean distance) to calculate inductance offers undoubted advantages over other methods. But so far it seemed to be limited to the case where the current is uniformly distributed over the cross section of the conductor, i.e. to DC (direct current).

Comparative Study of the Accuracy of Analytical Inductance Formulae for Square Planar Spiral Inductors
In the design of radio frequency (RF) microelectronic integrated circuits (IC’s) and of antennas for short-wave radio frequency identification (RFID) and telemetry systems, planar spiral coils are important components.
Inductance Formula for Square Planar Spiral Inductors with Rectangular Conductor Cross Section
Planar spiral coils are used as inductors in radio frequency (RF) microelectronic integrated circuits (IC’s) and as anten-nas in both 13.56 MHz radio frequency identification (RFID) and telemetry systems.
