Telecommunications Patents
Telecommunications refers to the transmission of information, such as voice, data, or video, over a distance using electronic means, typically through wired or wireless systems. Telecommunications technologies facilitate communication, information sharing, and coordination of activities. They are also employed for legal surveillance to monitor and gather evidence related to criminal activities.
Mast Mountable Antenna
- U.S. Patent # 10,468,743
The invention relates to mast-mountable antennas designed to withstand harsh weather conditions, maintain vertical polarization, and efficiently handle lightning surge currents. It addresses issues such as unintentional radio frequency (RF) currents along masts and mounting structures, optimizing antenna designs for radio frequency current flow, and managing lightning surge currents. The patent presents a novel mast-mountable antenna that minimizes interference, eliminates the need for exposed external feed lines, and provides a direct current path for lightning surge currents. Key objectives include preserving radiation patterns, suppressing RF currents along the feed line and mast, and directing lightning energy through the mounting structure while maintaining communication performance. The invention aims to offer a robust, weather-tolerant antenna solution for elevated locations with enhanced lightning tolerance.
Tulip Antenna with Tuning Stub
- U.S. Patent # 7,791,554
The invention pertains to antenna design, focusing on optimizing the impedance matching between transmission lines and antennas, as well as improving the radiation characteristics of antennas, especially those made from lossy materials. The antenna apparatus features a ground plane with a ground plane aperture, a tuning stub, and two intersecting planar radiating elements connected by a conductor. The design allows for adjustments to the tuning stub's thickness and diameter to enhance the antenna's high-frequency response. In essence, the invention aims to create more efficient antennas, particularly those constructed from lossy materials, by refining impedance matching and radiation patterns.
Controllable Telecommunications Switch Reporting Compatible with Voice Grade Lines
- U.S. Patent #7,388,947
This invention is about improving the way law enforcement receives information during electronic surveillance of phone numbers. Currently, there are complex and expensive methods for delivering this information, such as using special data circuits. The invention pertains to the field of telecommunications, specifically addressing the delivery of call identifying information from an Intercept Access Point (IAP) switch to a law enforcement data collection system. It aims to replace costly and complex data delivery circuits with a more economical method. The invention utilizes voice-grade lines in the Public Switched Telephone Network for data transmission, employing Frequency Shift Keying for information delivery and Dual Tone Multi-Frequency signaling for two-way command and control communication between the IAP switch and the data collection box. This approach improves cost-effectiveness, provisioning speed, and flexibility in connecting to law enforcement data collection boxes, compared to existing methods. The invention also introduces two-way communication, bandwidth control, and error detection and retransmission features to enhance the efficiency of surveillance data delivery.
