Simultaneously recording of video image and microscope stage position data

Claim 2

Method of making an examination of a specimen by use of a microscope comprising: a) mounting the specimen on a standard specimen platform, b) during a first session, placing the specimen platform on a specimen stage of the microscope, c) moving the specimen stage to a home position, d) conducting a microscopic examination of the specimen by moving the specimen by manipulation of the specimen stage while video recording the examination, e) during a subsequent session, placing the specimen platform on a specimen stage, f) moving the stage to the home position, g) displaying the taped image, and h) manipulating the stage with reference to the video image so that the image observed by use of the microscope is substantially the same as the video image.

Claim 3

The method according to claim 1 wherein the first session is conducted with an optical microscope and the subsequent session is conducted on an electron microscope having a stage compatible with that of the stage on the optical microscope.

Claim 4

The method according to claim 1 wherein during the subsequent session, the examination is video recorded and the display of the image of the first session is suspended during manipulation of the stage to observe images not observed during the first session.

Claim 5

The method according to claim 3 wherein the stage is returned to the position at which display of the recorded image of the first session was suspended and display of the recorded image of the first session is resumed.

Claim 6

Method of making an examination of a specimen by use of a microscope comprising: a) mounting the specimen on a standard specimen platform, b) during a first session, placing the specimen holder on a specimen stage of the microscope having a position encoder for generating digital signals indicative of position, c) moving the specimen stage to a home position, d) conducting a microscopic examination of the specimen by moving the specimen by manipulation of the specimen stage while video recording the examination and simultaneously recording the digital position signals in the audio band of the video signal, e) during a subsequent session, placing the specimen holder on a specimen stage having a position encoder for generating digital signals indicative of position and servo drive means for moving the stage to a desired position, f) moving the stage to a home position, g) displaying the recorded video image simultaneously recovering the encoded position data, and h) automatically manipulating the stage in response to the recovered position data so that the image observed by use of the microscope is substantially the same as the video image.

Claim 7

Method of making an examination of a specimen by use of a microscope comprising: a) mounting the specimen on a standard specimen platform, b) during a first session, placing the specimen holder on a specimen stage of the microscope having a position encoder for generating digital signals indicative of position, c) moving the specimen stage to a home position, d) conducting a microscopic examination of the specimen by moving the specimen by manipulation of the specimen stage while video recording the examination and simultaneously recording the digital position signals in the audio band of the video signal, e) during a subsequent session, placing the specimen holder on a specimen stage having a position encoder for generating digital signals indicative of position and servo drive means for moving the stage to a desired position, f) moving the stage to a home position, g) displaying the recorded video image simultaneously recovering the encoded position data, and h) automatically manipulating the stage in response to the recovered position data so that the image observed by use of the microscope is substantially the same as the video image.

Claim 8

The method according to claim 5 wherein the first session is conducted with an optical microscope and the subsequent session is conducted on an electron microscope having a stage compatible with that of the stage on the optical microscope.

Claim 9

The method according to claim 5 wherein during the subsequent session, the examination is video recorded along with digital position signals and the display of the image of the first session is suspended during manipulation of the stage to observe images not observed during the first session.

Claim 10

The method according to claim 7 wherein the stage is returned to the position at which display of the recorded image of the first session was suspended and display of the recorded image of the first session and automatic manipulation of the stage is resumed.

Claim 11

The method according to claim 5 wherein the digital data is encoded using FSK techniques.

Claim 14

A system according to claim 10 further comprising: e) means to drive the stage to commanded positions, f) means to replay the recorded video and recover the digital position signals therefrom, and g) means to supply the recovered position signals to the stage drive means as command signals.

Claim 15

A system according to claim 11 further comprising: means for recording an analog voice signal along with the video image, means for FSK encoding the stage position signals using two audio frequencies, and means for combining the FSK encoded stage position signals with the analog voice signal prior to recording.
