Abstract: A doorbell answering system includes is sensor to sense the presence of a visitor at an exterior panel. The system announces a message greeting to the visitor, asking the visitor to identify themselves. The visitor's response is recorded by the exterior panel and played at an interior panel, allowing a resident to monitor the visitor's response. The interior panel also records the visitor's response for subsequent playback in a controlled manner via a control panel. The system may store multiple visitor messages, each identified by a date and time.

Abstract: An apparatus and a method for determining output signals according to pressure and depressing time mainly includes a timer, a scanner and a keyboard connecting electronically to the timer and the scanner. The keyboard has a plurality of button keys. When in use, the timer is set to zero and stops counting time. Then the scanner scans the keyboard to locate the button key being depressed by an external force. A signal is output depending on the external force.

When the time counted by the timer exceeds the selected time period, a second signal is output. Thus input information may be entered through fewer button keys, and injury that might otherwise occur by using composite keys may be avoided.

Abstract: A portable tester verifies the operational status of a satellite-based navigation ground facility. The portable tester includes a receiver and a computer. In a preferred embodiment, the receiver obtains Global Position System (GPS) signals from a plurality of satellites and Very High Frequency (VHF) broadcasts from the ground facility. The computer compares the data obtained from the receiver with expected results and determines if the ground facility is operational.

As a result, a pilot may not receive accurate information regarding the aircraft's position. This may result in landings that do not closely follow a prescribed glidepath, which could be disastrous. By using the portable tester, the ground facility can be tested to ensure proper data will be sent to the aircraft.

In comparing the locating vector to the exemplary vectors, constraints are enforced on movements between locations (e.g., cannot pass through walls) and to probabilistically enforce expectations on transitions between locations.
