You and your teammate decided to create a system to predict fires and gas leaks and turn on an alarm if a fire or gas leak occurs and a motion sensor to detect if there is someone in the room. Microelectronic is a company where all the sensors you need can be found. The sensors (fire, gas leak and motion) you ordered were sent to you along with a datasheet that explained how you could connect them. You and your teammate decided that your system would work as follows: • A sound alarm will be triggered if there is a gas leak or fire in the room. • A light alarm will be activated if there is a gas leak or a fire in the room and someone is in it. Since both the gas and fire sensors cannot work at the same time, both the light, and sound will be off in this case. Assignment activity and guidance 1. According to the above description, your tasks are as follows: a) Illustrate and compose the Boolean expression describing each output of the system described above, by generating a truth table. b) Reduce the Boolean expressions obtained to its simplest form using Boolean algebra. c) Formulate a circuit that achieves the described system behavior using logic gates.

The SPEC's performance measurements are repeatable, but they're not reliable. Why?
If you have a factory for the manufacture of soap, where after manufacturing and placing them in their own molds, they are transferred to rooms with certain temperatures for freezing. A system that monitors this process and designs a simple alarm if the temperature rises above 40 degrees Celsius or drops below 20 degrees Celsius. Arduino

You are a nasa engineer who needs to monitor the situation every time a probe uses its thrusters. For a given day you are given the planned times when the thruster will be used. You need to be monitoring the situation at those boost times and for 5 minutes after. You want to figure out if you can take a break for a certain number of minutes. To achieve this you are given the planned boost times in in hours and minutes with an am/pm. And you are given a desired break time in minutes. Output if you can take the break or not given the monitoring you have to do. For example: If you know the thruster is fired at 5:00am and 12:50pm. You need to be monitoring the situation from 5:00am to 5:05am and again from 12:50pm to 12:55pm. Apart from those times you are free to take a break. So a 5 minute break is possible. But a 12 hour break is not possible. Note You should assume that the launch times that the user entered would occur in one day. However, you cannot assume that these were…
