Abstract
Abstract Apparatus for providing tactile feedback in response to the touch input command of a user to the touchscreen of a cathode ray tube in a CRT command and display system. An actuator is provided for imparting motion to the CRT when the actuator is energized. Energization occurs in response to a touch input command of the user to the touchscreen of the CRT. When energized, the actuator provides tactile feedback to the user by imparting motion to the CRT.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
Apparatus for providing acknowledgment of a touch input command of a user to the touchscreen of a cathode ray tube of a CRT command and display system, the apparatus comprising in combination: shock mounting means for mounting the cathode ray tube, the mounting means allowing limited movement of the cathode ray tube; an actuator means for imparting motion to the cathode ray tube when the actuator means is energized; energizing means responsive to a touch input command of the user to the touchscreen of the cathode ray tube for energizing the actuator means, whereby tactile feedback is provided to the user by the motion imparted to the cathode ray tube by the actuator means to acknowledge the touch input command.
Claim 2
Dependent Claim
120 words
Apparatus for providing acknowledgment of a touch input command of a user to the touchscreen of a cathode ray tube of a CRT command and display system, the apparatus comprising in combination: shock mounting means for mounting the cathode ray tube, the mounting means allowing limited movement of the cathode ray tube; an actuator means for imparting motion to the cathode ray tube when the actuator means is energized; energizing means responsive to a touch input command of the user to the touchscreen of the cathode ray tube for energizing the actuator means, whereby tactile feedback is provided to the user by the motion imparted to the cathode ray tube by the actuator means to acknowledge the touch input command.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 wherein the actuator means comprises a solenoid energized by the energizing means, an armature, armature stop means and means biasing the armature away from the stop means, the solenoid being effective when energized for moving the armature to contact the stop means to impart motion to the cathode ray tube.
Claim 4
Dependent Claim
25 words
The apparatus of claim 2 wherein the stop means includes an elastomeric surface that is contacted by the armature for inhibiting noise created by contact.
Claim 5
Dependent Claim
162 words
A CRT system comprising: a cathode ray tube having a touchscreen; a CRT chassis for carrying the cathode ray tube, the chassis having an open end through which the touchscreen of the cathode ray tube is exposed; means for mounting the chassis from the open end; an actuator mounted to the distal end of the chassis, the actuator including a solenoid, an armature, armature stop means and means biasing the armature away from the stop means, the solenoid being effective when energized for moving the armature to contact the stop means to impart motion to the CRT chassis and the cathode ray tube carried thereby; and means responsive to a touch input command of a user to the touchscreen of the cathode ray tube for energizing the solenoid to cause the armature to be moved to contact the stop means and impart motion to the cathode ray tube, whereby tactile feedback is provided to the user to acknowledge the touch input command.
Claim 6
Dependent Claim
162 words
A CRT system comprising: a cathode ray tube having a touchscreen; a CRT chassis for carrying the cathode ray tube, the chassis having an open end through which the touchscreen of the cathode ray tube is exposed; means for mounting the chassis from the open end; an actuator mounted to the distal end of the chassis, the actuator including a solenoid, an armature, armature stop means and means biasing the armature away from the stop means, the solenoid being effective when energized for moving the armature to contact the stop means to impart motion to the CRT chassis and the cathode ray tube carried thereby; and means responsive to a touch input command of a user to the touchscreen of the cathode ray tube for energizing the solenoid to cause the armature to be moved to contact the stop means and impart motion to the cathode ray tube, whereby tactile feedback is provided to the user to acknowledge the touch input command.
