Yard-Stick The Yard-Stick is a tool for the landscape planner, builder, architect, accident investigation professional, or anyone who needs to measure and record the outline of an irregular area. The device combines the familiar rolling wheel measuring instrument with an accurate digital compass, internal memory, display, processor, and RS-232 interface. The resulting tool can measure and record the outline of multiple areas, measure distances and direction between these areas, and then transfer this information to a PC for display and calculation. This information can then be used to produce both graphical and textual description of the scene. This data can be overlaid on photographic information to produce a complete record of the area.
Ultimate
Clock and Message Display The clock and message display presents the date, time, and an optional user-defined message in a scrolling marquee fashion. A large 320-LED display continuously scrolls the date, time, and user message across the display using a dot-matrix font. Bright LEDs and a large 8 × 8 font make the display easily readable from far away. The pushbuttons on the front of the clock allow for easy setup and changes. The clock is based on the 60-Hz AC commercial power grid for timekeeping accuracy and uses a “super cap” instead of batteries for backup.
The
Geo-Sentry The Geo-Sentry is a programmable real-time event recording and display system. It interrogates a series of small seismic sensors to detect foot or vehicle traffic. The system is designed to monitor these sensors and send X-10 commands when the level of activity from a sensor indicates that a person is walking in the area or that a vehicle is moving in the driveway. By associating a different X-10 command sequence and On time with each sensor, the outdoor lighting near the driveway and house can follow a person’s movement. This adds safety for the walker and security for the homeowner.
Electronic-Lab
The Electronic-Lab enables educational personnel to simulate analog and digital practice exercises with real devices. It provides the mounting surface for practices, the power source for the circuits, two signal generators, a clock generator, a 16-bit word generator, an I2C bus controller, a frequency meter, an oscilloscope for up to eight analog inputs, an oscilloscope for up to 16 digital inputs, and a 16-bit pattern detector. With the practice handbooks that are included, instructors can make the best use of PC resources to teach the student and to generate, monitor, and register the signals, as well as verify fixed-function SSI/MSI integrated circuits and programmable logic devices.
