Title: Variable lens system e.g. for endoscope zoom lens
Inventor: SEIDEL ROBERT
IPC: G02B26/08
Filed: 1997-03-14
Abstract: The system includes a lens chamber bounded by one or more diaphragms, which can be fully or partly transparent by changing the diaphragm thickness over the radius. Any arbitrary form of the curvature can be attained, e.g. elliptical, or hyperboloid, symmetrical, or asymmetrical. The diaphragm cross-section can also assume the shape of intermittent curves by support structures which can be exposed to tension and pressure, thus facilitating different formations. Typically both diaphragms of the lens may be different, or given different curvatures by different counterpressures.

Filed: 1997-08-16
Abstract: The bobbin drum drive is powered by an electrically commutated direct current (DC) motor, with a control (1) to set the output rating of the rotor according to a rotary angle transmitter. The system contains a stretch (S) for ideal conditions, with an ideal drive system (2) for the bobbin drum and a coarse resolution rotary angle transmitter system (2a) to give a simulated model (B) with a simulated bobbin drive (6) system, in parallel. The model (B) is fed with signals from the rotary angle transmitter (2a) for matching with the ideal stretch (S). At least one condition value ( omicron b) of the model is used as a control value. The simulated model (B) is disconnected by a switch (9) from the control circuit which sets the rotary speed of the drive motor rotor. The switch (9) is a threshold switch, which breaks the connection between the control circuit and the simulated model (B) when the angular speed ( omicron ) is over a given threshold value. The simulated model (B) is a Luenberger observer type. The output of the ideal stretch (S) and the corresponding output of the simulated model (B) are switched inversely to an addition point (8), and the sum is returned to an input of the simulated model (B) for a dynamic matching of the model (B) to the ideal stretch (S). The angular speeds ( omicron ist, omicron b) of the ideal stretch (S) or the simulated model (B) are fed to an addition point (5) together with an inverse feed of the nominal angular speed ( omicron soll), with its output linked to the control (1). The simulated model (B) input is connected to the output of the control (1).
