GPS Navigation Indoors

Because GPS requires a line-of-sight connection with satellites, it cannot work in urban canyons, in caves, or inside buildings. Inertial navigation works around this problem, while delivering sub-meter accuracy and full orientation data (yaw, pitch, and roll), with several times the update rate of conventional GPS navigation.For a short distance, you can navigate with reasonable precision, but for longer trips, your sense of relative location tends to drift. But if you know something about the environment - that the room gets warmer at one corner, or that the floor is slanted - the drift is reduced. Eliminating drift, and finding new senses to take advantage of, are the biggest challenges in developing a functional inertial navigation unit.Course Zero Automation is reducing drift in their device by incorporating a unique variety of sensors and developing software to determine the reliability and usability of each. Power consumption and cost will be reduced by using commercially available sensors intended for videogame and cell phone integration. A low-cost inertial navigation device will have uses outside the consumer handheld market. Aside from multiple applications in the defense industry, first responders will be able to use the same device to identify their location within a smoke filled building, or to identify the location of a fallen comrade.

Baby Monitors

Baby monitors are an essential part of baby gear. They give you a sense of comfort and let you get on with your day while your child is sleeping. When you have the baby asleep in the crib, you don't have to keep constantly checking to make sure that he/she is all right when you have a baby monitor. Every move and sound that the baby comes through the speaker so it is almost like you is in the same room. The transmitters in the monitors work best when they are within 10 feet of the baby. You can carry the receiver with you or leave it plugged in by your bed during the night. The basic models have a switch you use to turn them on and off and to adjust the volume. You can also use batteries when you want to take the receiver with you, rather than having to plug it into an outlet in each room. Some of the monitors on the market have a light display that flashes to let you know when the baby is crying. You don't need to have the volume turned up if you use this feature, but it does mean that you have to keep looking at the monitor. In one case we had neighbors with the same monitor on the same frequency and we could hear their entire night-time routine if our monitor was on. You also have to make sure that you keep the monitors away from bathtubs and pools because they are electrical devices.
