Monitors changes in the electrical characteristics of a vehicle (especially aircraft) relative to its environment to detect proximity to structures such as hangar walls. Provides early warning or automatic prevention of ground collisions, addressing the expensive problem of 'hangar rash' and ground-handling incidents.

Uses digitally encoded rumble strips and/or cross-correlation of broadband vehicle noise at multiple sensors to determine vehicle position, direction, and speed. Enables detection of wrong-way driving, off-trajectory vehicles, and potentially dangerous approaches to curves or ramps without requiring any vehicle-side equipment.

A local software agent that continuously checks LAN connectivity, DHCP, DNS, and internet reachability. Reports to a status server and acts on commands from a command server, including power cycling modems, access points, and other devices via controllable PDUs and power strips. Reduces truck rolls and shortens outage durations for ISPs and enterprises.

Lets a user dial a full 10-digit number once, then later dial just 7 digits and have the device automatically insert the correct area code. Uses a synthetic dial tone and double-burst tone to ask whether the number should be stored, reducing dialing friction for humans in an era of proliferating area codes.

Industrial design patent for a late-1990s-style wireless handset. The design emphasizes ergonomics, antenna placement, and physical layout of keys and display for comfortable single-handed operation.
