Title: John Robert Siemer: Innovator in Camera Technology
Introduction
John Robert Siemer is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of camera technology, particularly in the area of film loading and sensor gain adjustment. With a total of 2 patents, Siemer's work has had a lasting impact on photographic equipment.
Latest Patents
Siemer's latest patents include an "Apparatus and method for setting radial bar code disc sensor gain" and a "Camera apparatus and method for film double exposure prevention." The first patent describes a photographic film camera that utilizes a variable gain opto-sensor circuit. This circuit responds to a radial bar code data disk, generating a sensor output signal that transitions through a logic threshold. The microcontroller compensates for noise by adjusting the opto-sensor gain based on the transition count of the output signal.
The second patent focuses on a camera and method for automatically determining the usage condition of film in a cartridge. It employs a cartridge radial bar coded data disc to identify the initial angular settings of the film spool during loading. The camera can differentiate between exposed, partially exposed, fully exposed, or processed film, allowing for appropriate actions to be taken based on the film's condition.
