A proximity sensor includes an antenna having a resonant frequency selected to correspond to a resonant frequency associated with a selected dimension of an item of interest. In one example, the antenna is selected to have a resonant frequency corresponding to a resonant frequency associated with the width of a turbine blade. The amount of electromagnetic coupling between the item of interest and the antenna provides an indication of the proximity or distance between them. Several embodiments for incorporating such a structure into a gas turbine air seal are disclosed.

Proximity sensor

A video game having a controller for player selection of movement of a plurality of game objects, and for controlling the rate of movement of the selected game objects.

Video game with control of movement and rate of movement of a plurality

A video game including a player operated device for controlling the velocity and direction of movement of a game object. The game player may generate a pulse train having a pulse repetition rate proportional to the desired velocity of the game object. A numerical value of the pulse rate as a function of a clock signal is established, and the numerical value is utilized to change the address of the game object in a video memory so that in successive frames of a video display the game object moves across the display screen.
