Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

In this learning object you'll explore how agents of socialization shape a person's life and you'll map the significant events, places, and people that have shaped your life.

Learners will identify the number of significant digits in practice problems.

Students read the rules used in multiplying and dividing signed numbers. They view examples and work practice problems.

Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

Learners compare animations of analog and digital data signals. A short quiz completes the activity.

In this animated object, users view how a kanban signals production to start.

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Multimedia Principles - Signaling. Explore how using voice and visual cues can help your learners focus, organize, and process your content.

Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.

Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.

In this learning activity you'll explain how how Usability fits into User Experience Design.

In this animated, audio and graphic activity illustration, learners will view design criteria for properly storing property and evidence.

Learners will be able to identify areas within the property room including adjoining work areas, work flow, temporary storage, long-term storage, high profile items, bulk or oversize items, biohazards, hazardous materials, cold storage, administrative area, and release areas.

In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.

In this learning activity, you'll be introduced to three common usability research methods.

In this learning activity you'll gain tips for successfully completing welding assignments.
