This circuit uses a thin piezoelectric sensor to sense the vibrations generated by knocking on a surface; eg, a door or table. Basically, it amplifies and processes the signal from the sensor and sounds an alarm for a preset period. In operation, the piezoelectric sensor converts mechanical vibration into an electrical signal. This sensor can be attached to a door, a cash box, cupboard, etc using adhesive. A 1-1.5m long shielded cable can then be connected between the sensor plate and the input of the circuit. The signal generated by the sensor ....etc

Multichannel Data Acquisition Systems



Precision Analog Applications Seminar

Multiplexing allows one ADC to do the work of several in a multichannel system. Rather than dedicating an ADC to each channel, a single converter can read every channel in sequence. This can save power, since ADCs can use a significant amount of power while switches use very little, and it can save cost, since switches are much cheaper than ADCs.

Cooperative Asynchronous Multichannel MAC: Design, Analysis, and Implementation
Luo, T. Motani, M. Srinivasan, V. Nat. Univ. of Singapore, Singapore;
This paper appears in: Mobile Computing, IEE Transactions on Publication

Abstract
Medium access control (MAC) protocols have been studied under different contexts for decades. In decentralized contexts, transmitter-receiver pairs make independent decisions, which are often suboptimal due to insufficient knowledge about the communication environment. In this paper, we introduce dis ....etc

Abstract

Necessity of data acquisition system in instrumentation: -

- All engineering activities require collection of data, in development, production, quality control, management, process control etc.
- We have been using thermometer, voltmeters, scales, oscilloscopes and such variety of measuring devices and instruments to read the physical data.
- The emphasis is therefore on getting the machines to meet most of our data acquisition and control needs.
- Data acquisition is collecting data or information that describes the gi ....etc

Abstract

It might have observed at various places where numerous counters are there, you are always confused as to which queue you should select to get your work done. In usual cases you select the smallest queue and end up leaving the counter late. By utilizing this system the inordinate delay in transacting your business can be overcome since you need not have to stand in any queue. You can deport after finishing your job much earlier than expected. This is again very highly useful and cost effective project. ....etc

Abstract Topology engineering concerns with the problem of automatic determination of physical layer parameters to form a network with desired properties. In this paper, we investigate the joint power control, channel assignment, and radio interface selection for robust provisioning of page link bandwidth in infrastructure multiradio multichannel wireless networks in presence of channel variability and external interference. To characterize the logical relationship between spatial contention constraints and transmit power, we formulate the joi ....etc
