Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device, the scanner and stabilizer comprising: a mounting plate; a first electrodynamic driver attached to the mounting plate; a second electrodynamic driver attached to the mounting plate; control system means connected to the first and second electrodynamic drivers for driving the drivers through drive leads connected to the drivers and receiving position feedback of the drivers through position leads connected to the drivers; a flexible pivot attached to the mounting plate; flexible mounts attached to the drivers; and a reflector attached to the flexible pivot and the flexible mounts of the drivers, the drivers disposed in various predetermined positions adjacent the reflector for moving the reflector on the flexible pivot in a desired scanning pattern, such as conical, rosette and raster among others.
Claim 2
Dependent Claim
138 words
An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device, the scanner and stabilizer comprising: a mounting plate; a first electrodynamic driver attached to the mounting plate; a second electrodynamic driver attached to the mounting plate; control system means connected to the first and second electrodynamic drivers for driving the drivers through drive leads connected to the drivers and receiving position feedback of the drivers through position leads connected to the drivers; a flexible pivot attached to the mounting plate; flexible mounts attached to the drivers; and a reflector attached to the flexible pivot and the flexible mounts of the drivers, the drivers disposed in various predetermined positions adjacent the reflector for moving the reflector on the flexible pivot in a desired scanning pattern, such as conical, rosette and raster among others.
Claim 3
Dependent Claim
81 words
The scanner and stabilizer as described in claim 1 wherein the control system means includes drive electronics connected to the drive leads of the drivers and a feedback processor connector connected to the position leads of the drivers, the feedback processor connected to the drive electronics; a position controller connected to the drive electronics for generating position signals to the drive electronics and a pattern generator connected to the position controller for signaling the position controller and generating a desired pattern.
Claim 4
Dependent Claim
250 words
An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device, the scanner and stabilizer comprising: a mounting plate; a first electrodynamic driver attached to the mounting plate; a second electrodynamic driver attached to the mounting plate, the drivers including a ferromagnetic housing having a drive coil and a position coil mounted therein, the drive coil disposed around the position coil with a permanent magnet mounted inside the position coil, when the driver is energized, the drive coil moving linearly in relationship to the position coil, the drive coil connected to a connecting plate; control system means connected to the first and second electrodynamic drivers for driving the drivers through drive leads connected to the drivers and receiving position feedback of the drivers through position leads connected to the drivers, the control system means having drive electronics connected to the drive leads and a feedback processor connected to the drive electronics and the position leads, the drive electronics controlled by signals from a position controller, the position controller connected to a pattern generator for receiving a desired scanning pattern command signal; a flexible pivot attached to the mounting plate; flexible mounts attached to the connecting plates of the drivers; and a reflector attached to the flexible pivot and the flexible mounts of the drivers, the drivers disposed in various predetermined positions adjacent the reflector for moving the reflector on the flexible pivot in a desired scanning pattern such as conical, rosette and raster among others.
