Latest Patents

One of his notable inventions is a photographic film printer. This printer includes a housing, a lamphouse, negative handling portions, filters, paper handling portions, and a reflex viewing mirror that allows for viewing negatives while positioned at the printing station. Additionally, it features a linkage that enables a negative pressure plate to ensure firm engagement and retention of a negative strip. The printer also includes a splicing station for joining successive negative strips, along with paper handling and cutting features. Shutter operating elements are incorporated, and systems are in place to resist undesired light entry into the printer's interior. Furthermore, it allows for remote, manual advancement of the negative strip.

Another significant invention by Chae is a direct reading digital colorimeter. This innovative blood analyzer can simultaneously perform a specific blood test and read the prothrombin time on a separate digital readout device. The program circuit module, equipped with appropriate calibration parameters, performs specific tests and provides a direct display of the desired blood constituent concentration. The analyzer features an independent prothrombin well with a separate optical source for prothrombin time measurement, displaying results on an independent readout. It also includes a built-in digital readout quartz crystal timing device, which can operate independently of prothrombin time analysis. The compact console design includes controlled incubated storage for blood test samples and insertion cavities for both constituent concentration and prothrombin time analysis. The results are normalized and presented on an independent readout device, providing nearly instantaneous display following the initiation of any test.
