Latest Patents

Two of Jacobson's latest patents showcase his ingenuity and technical expertise:

1. **End of Rewind Detector for a Telephone Answering Device**

This invention features an end of rewind detector that utilizes a tape cassette with a spindle. By incorporating a rotating member made of conductive plastic containing carbon particles, it achieves intermittent conductivity. An electrical feeler, in physical contact with the plastic material, detects variations in electrical conductivity. The termination of this variation signals the end of the spindle's rotation, enhancing the functionality of telephone answering devices.

2. **Miniature Telephone Answering Device with Single Head Carriage**

In this invention leveraging microcassettes, a single head carriage is responsible for managing the pinch rollers and heads for both outgoing announcements and incoming message tape cassettes. The carriage can move linearly between engaged and retracted positions through a unique cam assembly, which includes a cam with missing teeth in specific areas. This innovative mechanism allows for selective engagement of idler wheel slider assemblies, responding to the head carriage's position and the direction of the cassette drive.
