An increasing voltage follower can be converted into a ideal half wave rectifier by adding two diodes as shown in circuit diagram. When Vin is positive Vo becomes negative and diode D1 gets Forward biased at the same moment diode D2 is reverse biased. When Vin becomes negative, Vo becomes positive and diode D2 gets forward biased corresponding to the applied sine wave Vin. Positive going ripples appear at output V2 and negative going ripples appear at output point V1. Read More.....

Victorinox has launched a memory stick design which is, says the company, the most secure of its kind available to the public. The Victorinox memory stick uses several layers of security including fingerprint identification and a thermal sensor.

Analysis focuses on investigation and definition of the problem, rather than on how the solution will be defined. For example if a new library catalog system is to be developed, analysis would focus on defining the business processes related to its use.
