Title: Accordion key mechanism with valve and check device
Inventor: WOERL HANS
IPC: G10D11/02
Filed: 1995-11-04
Abstract: The mechanism applies additional force by compression springs (20,22) whose effect is limited to a short path, less than 3 mm, close to the key lever (10) end position in both directions. The spring constants are such that the lever re-sets to rest in less than 0.l5 seconds. The springs oppose the key pressure but hold the key (14) and lever in front of an end stop (18) defined note position at a key load of 0.2 N. The total spring force plus the off-load key re-setting force has a spring constant in one of both end positions which produces a resonance frequency below 16 Hz due to the mass on one or both springs. The two springs hold the valve parallel in a note position to the keyhole board (1).

Abstract: A rangefinder for a camera with a zoom lens comprises two lenses 25', 26' each forming an imageon a respective line sensor 27', 28'. Each line sensor has a plurality of light receiving elements. Some of the light receiving elements in each sensor are used as light receiving areas. The light receiving areas are shifted in accordance with the current focal length of the camera lens, the distance between the camera lens and the image forming lenses 25', 26', the camera mode (macro/regular) or to provide a number of measurements which can be assessed for reliability. The size of the areas may be varied in accordance with the image contrast or correlativity. The intensity of the brightest point on each sensor may be compared in order to normalise the output of one sensor. A backlit scene may be detected on the basis of the difference between the maximum and average scene brightness. The outputs of each light receiving element included in the light receiving areas are integrated to produce image data and to determine the range to any object in the field of view.

Title: Light intensity controller
Inventor: BRAUN UWE PETER DIPL ING
IPC: G05D25/02
Filed: 1996-03-30
Abstract: The light intensity controller for the detection of point light intensities including from remote reflecting surfaces is based on the lens refraction law: "Incident luminous flux is approximately equal to luminance of light source x projected surface area".

Title: Pulse width modulation circuit for several channels
Inventor: CHO DONG SOO
IPC: H03K7/08
Filed: 1996-05-20
Abstract: The input cycles are processed by a counter, generating a count signal, contg. several bits. A counter (20) is coupled to a counter changer, effecting the signal bit value. A register receives and stores a data input from a data bus (25). This is coupled to a comparator (22), transmitting a setting signal, when the changed signal bit value has reached a preset level.
