Hair Dryer

 

************************************************************************
Q: What are some possible applications of a hair dryer? Can one remove dust from electronic components using a hair dryer? A: As shown in the video... *** Applications:
d) Use it for Air circulation and an alternative to a fan - Funny odor *** Relevant Article: “Any socket you plan to use to plug in a hair dryer should have RCD (residual current device) Protection. An RCD is a life-saving device that protects against dangerous electric shock and reduces the risk of electrical fires. If you don’t have RCD protection in your fuse box for your sockets, consider using an RCD plug to protect you and your property from serious appliance faults. Safe Use... Once you’ve finished using the hair dryer, unplug it and let it cool on a heat-resistant surface....... Don’t use a hair dryer while you’re in the bath, or near a sink full of water. Don’t reach for the hair dryer if it falls into water - unplug it straight away and then remove it. Check the cord of your hair dryer regularly for any signs of damage. If you spot any damage, replace it. Always unplug your hair dryer from the mains when not in use. Do not rinse or submerge in water, and ensure that the plug and cord do not get wet. Keep the power plug and cord away from heated surfaces....” (“Hair Dryers”, https://www.electricalsafetyfirst.org.uk/guidance/product-safety/hair-dryers/) ****************
Relevant material on electronics and dust: "Integrated circuits (ICs) can suffer from overheating due to the insulating effect of dust as well as suffer from electrical shorts caused by dust across their contacts. The most susceptible ICs are those having a metal lid acting as a heatsink cooling surface. To prevent overheating and failure, this metal surface and heatsink need to be essentially dust-free. Dust acts like an insulating blanket, preventing proper convection cooling. Test show that the temperature of some of the higher power PC components, such as the CPU, can go up nearly 30oF due to a build-up of dust. This is a significant increase in temperature and can lead to complete and abrupt part failure.... Another reliability problem is circuit shorting. Modern integrated circuits have as many as 100 exposed electrical contacts per inch. Designers rely on an air- gap between these contacts to prevent electrical shorts or cross-coupling of signals. Dust containing conductive material such as water, oils, and metallic elements can cause signal errors and abrupt part failure. Some manufactures now seal the contacts with a plastic coating once the part is soldered onto the circuit board in order to avoid signal shorting due to dust. In order to avoid these serious electrical problems, dust ingestion into the computer processor case and monitor needs to be minimized.... PCs have numerous mechanical devices and manual controls whose performance suffers when exposed to excessive amounts of dust. These include optical disk drives (CDROM/DVD), floppy/ZIP disk drives, keyboard, mouse, and commonly used interfaces such as USB ports. Internal interface cables and expansion slots can become unusable if exposed to excessive dust as illustrated below.... The keyboard and mouse are also affected by dust. Though these are easy to replace items, their reliability can degrade rapidly when infused with dust. Stuck keys and “sticky” mouse operation are most frustrating to operators and can create both errors and productivity loss.... It is not possible to precisely predict the lifespan reduction of operating a PC in an environment that has a higher concentration of dust than the environment the PC was designed for (the office or home environment)...” (“SPECIAL REPORT: EFFECTS OF DUST ON COMPUTER ELECTRONICS, AND MITIGATING APPROACHES", https://www.computerdust.com/downloads/special_report_on_the_effect_of_dust_on_electronics.pdf)

Programming Commercial Glass Sliding Doors

*** Relevant Background :  " An  automatic door , also known as an  auto door , is a  door  that opens automatically, without the need for human intervention or usually upon sensing the approach of a person. A person can be detected by microwave pulses,  infrared sensors  , or pressure-sensing pads...  " ( Automatic door - Wikipedia ) ***  Relevant Material :  " THEY HIT PEOPLE MORE OFTEN THAN YOU THINK AND CAN CAUSE SERIOUS PERSONAL INJURY Most of us walk through automatic doors on a regular basis. Most retail stores have some form of automatic doors, whether they are sliding doors, revolving doors, swinging doors, or folding doors. Most people who pass through automatic doors don't think about the fact that they can be struck by the door or trapped between the door and door frame. We expect them to simply open for us and close behind us. But often, that is not the case. When an automatic door hits you, you don’t expect it. It can throw...

  ******** " Question Is cycling associated with risk of all-cause and cardiovascular disease mortality among persons with diabetes? Findings In this cohort study of 7459 persons with diabetes, cycling was associated with at least a 24% lower all-cause mortality rate when compared with noncyclists, independent of other physical activity and putative confounders. Taking up cycling over a 5-year period was associated with at least a 35% lower risk of all-cause mortality when compared with consistent noncyclists. Meaning Cycling could be encouraged as an activity for persons with diabetes to lower the risk of premature mortality.. "  (Larsen et al., n.d.) **** Relevant Insurance Coverage: a. Liability for property damage and injury b. Personal and commercial liability, Liability of a landlord and tenant for property damage and injury c. Personal property coverage that covers theft d. Travel & health e. Business Liability Coverage f. Product Liability Coverage *** References ...

Blood Pressure Monitor

Image
**** Relevant Background: “ Arterial blood pressure  is most commonly measured via a  sphygmomanometer , which historically used the height of a column of mercury to reflect the circulating pressure. [1] Blood pressure values are generally reported in  millimetres of mercury  (mmHg), though  aneroid  and electronic devices do not contain  mercury .… For each heartbeat, blood pressure varies between   systolic   and   diastolic   pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the   cardiac cycle   when the   ventricles   are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is 120 mmHg   systolic   and 80 mmHg   diastolic   (written as 120/80 mmHg, and...
