Relevant Background: "A refrigerator (colloquially fridge) consists of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. Refrigeration is an essential food storage technique in developed countries. The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).[1] A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half..The refrigerator allows the modern household to keep food fresh for longer than before. Freezers allow people to buy food in bulk and eat it at leisure, and bulk purchases save money..Freezer units are used in households and in industry and commerce. Food stored at or below −18 °C (0 °F) is safe indefinitely.[13] Most household freezers maintain temperatures from −23 to −18 °C (−9 to 0 °F), although some freezer-only units can achieve −34 °C (−29 °F) and lower. Refrigerator freezers generally do not achieve lower than −23 °C (−9 °F), since the same coolant loop serves both compartments: Lowering the freezer compartment temperature excessively causes difficulties in maintaining above-freezing temperature in the refrigerator compartment. Domestic freezers can be included as a separate compartment in a refrigerator, or can be a separate appliance. Domestic freezers may be either upright units resembling a refrigerator, or chests (with the lid or door on top, sacrificing convenience for efficiency and partial immunity to power outages).[14]...In a house without air-conditioning (space heating and/or cooling) refrigerators consumed more energy than any other home device.[21] In the early 1990s a competition was held among the major manufacturers to encourage energy efficiency.[22] Current US models that are Energy Star qualified use 50% less energy than the average models made in 1974.[23] The most energy-efficient unit made in the US consumes about half a kilowatt-hour per day (equivalent to 20 W continuously).[24] But even ordinary units are quite efficient; some smaller units use less than 0.2 kWh per day (equivalent to 8 W continuously). Larger units, especially those with large freezers and icemakers, may use as much as 4 kW·h per day (equivalent to 170 W continuously). The European Union uses a letter-based mandatory energy efficiency rating label instead of the Energy Star; thus EU refrigerators at the point of sale are labelled according to how energy-efficient they are.The main refrigerant now used is R-600a, or isobutane which has a smaller effect on the atmosphere if released. There have been reports of refrigerators exploding if the refrigerant leaks isobutane in the presence of a spark. If the coolant leaks into the fridge, at times when the door is not being opened (such as overnight) the concentration of coolant in the air within the fridge can build up to form an explosive mixture that can be ignited either by a spark from the thermostat or when the light comes on as the door is opened, resulting in documented cases of serious property damage and injury or even death from the resulting explosion...Regarding total life-cycle costs, many governments offer incentives to encourage recycling of old refrigerators" ("Refrigerator", https://en.wikipedia.org/wiki/Refrigerator)

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.

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...
