weighted inputs based on the parameter of interest’s value. They give resultsof a spectral-like function (pattern). Spectral-based methods come in two forms: beamformingtechniques and Sub-space based methods. In beamforming, the beam is “steered” to look throughthe entire range of values of the desired parameter by adjusting the weighting of sensors appliedto incident signals. The most common beamforming method uses Bartlett beamformer and iscalled the Delay-and-Sum method. Essentially the weights are constrained to a complexmagnitude of 1 and the phase is adjusted. The weighting essentially mathematically delays thesignals and adds the results to maximize the output. This is done for all values of the angleparameter. Peaks within the spectrum are

and limitationsin the available instruction time. The mechanical engineering program at North Dakota StateUniversity offers mechatronics education in one semester as a three-credit undergraduate course.Due to the spectrum of its contents, the allocated three credit time is inadequate for this course,as such it was necessary to carefully develop the teaching materials so that it effectively meets itseducational objectives, yet without overloading the students. This paper discusses experiencesgained in preparing and teaching this course over a time span of three years.1 IntroductionIt is a well known fact that most of modern products are an integration of mechanical sys-tems, electronic systems, control systems, and computer systems; they are

The goal was to provide students with a set ofinstructions that were open to interpretation. In this way, it becomes possible to qualitativelyestablish a baseline for how students would approach this sort of task. By assigning the task inthis manner, it was expected that there would be a wide variety in the quality and completenessof student submissions. Find an example of an object that demonstrates particle or rigid body equilibrium around campus. Capture a photograph of it. Write a one paragraph explanation of the photograph that includes at

Throughout the semester long course, thestudents became more familiar with the CEENBoT and investigated hardware and softwareadditions to enable the CEENBoT to complete various tasks. Figure 1.

manipulate in one operation, the microcontroller can be classified as 8-bit, 16-bit, 32-bit, and so on. In general, 8-bit and 16-bit microcontrollers are targeted toward simplerapplications that do not require high performance whereas 32-bit microcontrollers are targetedtoward more complicated applications that require much higher performance. The usefulness of amicrocontroller is greatly determined by the peripherals added to the chip. Over the years,microcontroller peripheral functions to a large extent have been standardized. For example, thefollowing peripherals [1, 2, 3, 4] are common to most microcontrollers: 345 Parallel I/O ports: An I/O port consists of a set of I/O pins (8, 16, or even 32
