However, different researchers have examined different characteristics of engineering studentswithin the scopes of their own research interests, no universally agreed upon definition of engineering students’characteristics exists in the current literature. In this paper, a comprehensive review and analysis of the existingresearch on the measurement of the characteristics of engineering students is presented. Specifically, attentionhas been given in addressing the following questions: 1). what characteristics of engineering students have beenmeasured? 2). what research questions

applications of feedback control techniques.1. IntroductionThe ball-on-beam balance system is a classic example of feedback control systems. The problem is tomaintain the position of a ball at the center of a beam on which the ball rolls along freely. The ball willreturn to the center position after it has been displaced from this location. This system is an effectiveeducational tool for teaching feedback control principles. Some of these systems are commerciallyavailable[1,2,3].The set-up of our ball-on-beam system is shown in Fig. 1. The beam is a 55” long, grooved aluminumbeam that a regular rubber ball can roll along freely. The beam is mounted at the center to a servo motor,which can tilt the beam in clockwise and counter-clockwise directions

experimentally after it was shown geometrically, theyoungsters cut out symmetrical geometric shapes and hung them with a plumb-line from two points ondifferent lines of symmetry confirming that their intersection was the center of mass as shown in Figure-1. Through simple qualitative discussion and demonstration the students were introduced to the fact thatfor every object, regardless of its shape and size, when freely suspended from any point on the shape, aplumb line will always pass through the center of mass. Using two points not on the same line of “masssymmetry” will result in an intersection which is the mass center of the object as illustrated in Figure-2.During this experiment the principal of gravity and how it works was explained and

apre existing grinder.Of critical importance to the design was a wide range of adjustability so that the final product could fit avariety of bicycles. The stand would need to fit bikes with tire diameters ranging from 20” to 26”, andalso with varying rear axle widths. The design also had to allow for adjustment of the tension in the drivebelt, so it was decided that the grain crusher’s location would be adjustable to provide such tension. Theonly fixed components would be the center drive axle and its supports. An overview of the previousdesign is shown below in Figure 1 (Bonzella et al., 2006). An effort was also made to use as many off-the-shelf pieces as possible. This would limit machining time.Figure 1: Initial Design of the Bicycle

It is important to apply some level ofsecurity so that it will be difficult to be attacked, especially when they are used in critical applications [1].

CURRENT BLUETOOTH STANDARD The Bluetooth Version 1 standard gives specifications for voice and data communication over a radio channelwith a maximum capacity of 1Mbps, though Version 2 enhanced Bluetooth claims to have attained an impressive datarate of 2.1 Mbps. Bluetooth devices use the complete ISM band, while never transmitting from a fixed frequency for more than avery short time. This ensures that Bluetooth conforms to the ISM restrictions on transmission quantity per frequency.The available frequency spectrum is divided into 79 channels 1 MHz apart.

Amplitude is typically 1 milli-volt peak to peak in the presence of much larger (1000 timeslarger) external high frequency noise plus 50/60 Hz interference common mode voltages (common to allelectrode signals). We present a method to eliminate much of the noise using a pre-amplifier design withhigh common mode rejection ratio and high input impedance.
