Latching relays are also called “keep”, “impulse” or “stay” relays. It has two relaxed states – bistable.  It is bistable because when current is switched off, it remains in its last state. This can be achieve by two methods.

1. A solenoid operating a ratchet and cam mechanism.: The first pulse to the coil turns the relay on and the second pulse turns it off

2. By having two opposing coils with an over-center spring or permanent magnet to hold the armature and contacts in position while the coil is relaxed : a pulse to one coil turns the relay on and a pulse to the opposite coil turns the relay off. This type of relay has the advantage that one coil consumes power only for an instant, while it is being switched, and the relay contacts retain this setting across a power outage.

Latching relays are widely used because conventional relays need constant supply of voltage or power but latching relays dont.

Latching relays are not always that easy to find . You may find them in ebay but this ( www.sherburn.com )online site exclusively deals with latching relays products. I found it very useful

I have been thinking of creating a business plan. An idea struck my mind today and its about developing a medical alert system for old people when suddenly something happens to them and they are not even in a condition to call someone . Old people are getting more and more independent because of numerous reasons. And because of sudden problems they generally get because of the old age its impractical to always be monitored. I was thinking of developing a device for such elderly people so that whenever they feel emergency help they could get connected to 24*7 helpline and get immediate help. Also suddenly when they fall down because of  some stroke or anything and are unconscious even to call or press buttons in device the device should automatically send alert signal to the helpline number.

I searched about this kind of device and system if it already existed . And yes to my surprise it does. 🙁 . Its a very good system and they have done it well.. exactly the way i had the plan in my mind. The company name is Brick House Alert . Their specialization is in Medical Alert system.

Let me give you guys a background here. Now that i am an MBA student there are numerous management stuff i have been going through and today i found an interesting management field called Fleet management . Going deeper in knowing about this i have gotten some information which made my concepts clear about this new field of management – Fleet management. The information below about fleet management has been taken from this site

Fleet management, also known as fleet maintenance, is a standard of procedure, with a goal to keep a company or agency’s multiple vehicles and their operators in top-running condition. One of the highest costs of doing business is labor, followed closely by mobile assets including cars, vans, trucks, even boats and airplanes. Fleet management also covers large, moveable equipment related to the operation of the organization.

The primary objective of fleet management is twofold:

• Establish close monitoring by home base of drivers in the field, for the most efficient and effective delivery of goods and services.
• Control the costs of operating and maintaining vehicles and equipment, to retain their values and extend their useful lives.

Fleet management is about establishing the best possible level of control over an inconsistent environment, where factors such as weather, traffic, breakdown, customer demand and availability of manpower and equipment can change from day to day or hour to hour.

How GPS Tracking Helps Fleet Management

GPS tracking is the preferred and most up-to-date method of fleet management. GPS tracking systems, which use U.S. Department of Defense satellites for location and navigation, are accurate and reliable and greatly reduce incidents of human error.

By a mathematical formula called triangulation, the GPS tracking receiver will find its location, usually within a few feet of accuracy. Incremental position updates are made every few seconds or minutes.

The data collected includes:

• Day and time
• Directional heading
• Latitude and longitude (or street address)
• Duration of stops
• Speed of the vehicle
• Miles logged
