logic gates

          In hospitals, babies sometimes need to be kept warm in incubators for a period of time after birth. Design a system that will sound an alarm if the incubator gets too cold.

          when it doesn't sense as much eat it turns on with the not gate and when it does sense heat the alarm stays of

Patients need extra attention after serious operations. We would like to have push buttons for patients to use that will sound a warning at the nurse’s station only during the daytime. At night there is a different system  for patients to use. Design a patient warning system that will only work during the daytime

            the switch is to tell if it's day or not, and the button is in the patients room to press, but it only works when the switch is on meaning its is day

         

 

          Mr and Mrs Gonzales would like an automatic system to turn on their outside light at night and then off at dawn. Design an automatic lighting system with a manual override. Be careful the light must turn on during the day BUT not off at night.

          when the button is pressed it means it senses light so you put a not gate. that makes it turns on when it doesn't sense light. also you can turn it on in the day, but not off at night

        Some hospital rooms get very warm in the summer. We need an automatic fan to cool the patients. The fan should also be able to be turned on manually. Design this fan control system.

          when it gets hot the sensor turns it on or you can flick the switch and it will turn on, but you cannot turn it off this way.

         Ornithology deals with the study of birds. When photographing these creature, one needs to be very careful not to scare them. Design a remote camera shutter release that will be activated when the birds are on the feeding table. The camera should only work in daylight hours.

         the switch shows if its day and if it is day then if the bird sits on the feeding table it will turn on, but if its night then it will do nothing.

        

Air conditioning systems in apartments and houses are controlled by a thermostat. Design a system that will turn on the A/C system when the temperature rises above the thermostat setting. A manual control switch should also be included for continuous operation of the system.

when the temperature rises one of the switches gets turned on, and then you can turn it on and off with the other switch

A thermostat controls heating systems in apartments and houses. Design a system that will turn on the heating system when the temperature falls below the thermostat setting. A manual control switch should also be included for continuous operation of the system.

When the temperature rises one of the switches acts as a heat sensor and turns on which in turn make it go off because the not gate, then you can use the other switch to turn it on and off whenever you want

Many people who own cars protect them from theft and vandalism with an alarm system. Design an alarm system that will light a strobe if the car is tampered with. This alarm should remain lit until the owner deactivates the system.

When the car has not been tampered with it doesn't set off the alarm, but when it gets tampered with it sets off the alarm and to stop it you flick the other switch.

 

Many homes have automatic garage door openers. These systems need to have an emergency shut-off so that they can be operated without fear of injury to anyone. Design a system that can be disabled automatically in the event someone is in danger of being struck by the moving door and that will also stop automatically at the end of its downward travel. (Hint: The system requires two logic gates.)

the first switch is when the car is there then the second is to turn it off and the button is sensing when it is closed
