Title: Piet B. Hesdahl: Inventor in Remote Control and Speech Recognition
Introduction
Piet B. Hesdahl is an inventor based in Hilversum, the Netherlands. His patent work includes technologies for filtering remote-control codes and activating voice-controlled functions in multi-station networks. He is associated with 5 patents.
Latest Patents
One of Hesdahl’s latest patents describes remote-control code filtering for relaying remote-control codes. The system compares part of a received code with corresponding portions of stored codes, then determines whether to forward the code, discard it, or add a new code to storage. Codes may arrive through a network or a hardware interface and can be relayed onward through either route.
Another patent concerns activating voice-controlled functions in a multi-station network using both speaker-independent and speaker-dependent speech recognition. The system initially recognizes speech without relying on a particular speaker. When recognition succeeds, it can store a corresponding speech template and associate it with the originating station. Later speech from that station can be checked against its stored templates, with speaker-independent recognition available as a fallback.
Career Highlights
Hesdahl’s listed company affiliations include U.S. Philips Corporation and Koninklijke Philips Corporation N.V. His patent portfolio reflects work on communication and control systems, particularly the processing of remote-control commands and speech-based interaction.
Collaborations
His listed coworkers include Cornelis M. Klik and Gijsbertus M. Besselsen. Their names appear alongside Hesdahl in connection with his professional and patent-related work.
Conclusion
Piet B. Hesdahl’s inventions address practical ways to relay remote-control commands and enable voice-controlled functions across networked stations. His work combines code filtering, speech recognition, and adaptable system behavior.
