Title: Ronen Ezra: Cable Modem Innovations

Introduction

Ronen Ezra is an inventor based in Kfar Saba, Israel. His work includes innovations in cable modem tuning and power management. He is credited with 2 patents.

Latest Patents

Ezra’s patent, “Single Chip Tuner Integrated Circuit for Use in a Cable Modem,” describes a single-chip design for receiving multiple video channels. The circuit uses multiple tuner sub-circuits, each configured to generate an output channel based on a tuning command. It converts the selected radio-frequency signal into a baseband channel, which is filtered and amplified before being processed by the modem’s physical-layer circuitry.

His patent, “Apparatus for and Method of Reducing Power Consumption in a Cable Modem,” addresses battery-backup operation. When external power fails, the modem can request a switch from multi-channel DOCSIS 3.0 operation to single-channel DOCSIS 2.0 operation. If approved by the cable head-end, the modem can deactivate higher-power components, use narrower-band circuitry, and adjust its tuner filters and upstream amplifier to reduce power consumption.

Career Highlights

Ezra’s career includes work at Texas Instruments and Intel. His patented work reflects a focus on cable modem circuitry, including multi-channel reception and efficient operation during power outages.

Collaborations

Ezra’s coworker includes Shaul Klein. The available information identifies this professional connection but does not specify a particular joint patent or project.

Conclusion

Ronen Ezra’s patents address practical cable modem challenges, combining multi-channel tuning capabilities with techniques for reducing power use during battery backup.
