This device is a dispenser for a measured amount of liquid, bleach, water softener, etc., into a toilet tank with each flush. The valve works on the principal of differential densities between water and the valve shuttle. The volume dispensed is the volume of the cavity formed by the valve shuttle and the base of the unit.
When blind persons (BP in further text), approach street crossroads with trafffic lights, they usually face the issue, how to detect WHICH beep sound is for WHICH direction? Beep sound is the same for both directions, although there are some tries to make 2 different beeps, they are not connected to walk direction at all.
TransNet 2.0- an integrated transportation system for the 21st century
Ground transportation in its different modes (road, rail, pipelines, utilities, etc) represent a growing requirement for a modern society. At the same time such infrastructures requires not only huge financial investment usually from state agencies but also large amount of areas that are taken away from city functions ,
Transplantable unions of living cells and electronic circuits interfaced with body parts, will be used to test, measure, monitor, control, repair, replace, or assist the functioality of body parts.
Ordinary cells and stem cells are deposited upon, grown, attached to, united, and coupled with non-rejectable electronic circuits, sensors, radio tranceivers, optical, electro-optical, and/or computer systems,
The plan is to develop a refined HPWH optimized for a home with a PV system in three major ways not found on typical HPWHs. It is significantly more efficient than current HPWHs since it can extract heat from water as well as air, it can store low-cost energy to reduce use of higher cost energy,
PROBLEM/MOTIVE: In Cycling, the Cyclist faces two obstacles:
-there is dead-center at top of pedal-stroke, where Cyclist must apply huge force resulting in negligible torque and
-there is not even slight helping overlapping of pedaling power-periods (when Cyclist produces work), resulting that each single leg has to be so strong to move the bicycle alone.
Have you ever found yourself driving behind a semi-trailer truck? If you’re on a single-lane highway or road, it can be a nightmare. Even though the truck is driving relatively slowly, you cannot overtake it due to its size, and because you cannot see what is happening in front of the truck. However,
The present application relates to precision mechanical tools, and more particularly to a combination tool for tensioning a fastener, for example as done when truing and aligning a tension-spoked wheel.
Many precision assembly operations require measuring the amount of tensile strain applied to fasteners. For example, in the fabrication of engines and pressure vessels,
