The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...
In September 2015, Hillrom bought Welch Allyn Inc. [4] Hillrom continued to use the Welch Allyn brand name for some of its patient monitoring and diagnostic equipment. [4] In 2018, Hillrom updated its hospital bed model to include EarlySense’s vital-sign bed sensors to monitor patients’ heart and respiratory rates. [8]
Subsurface exploration usually involves in-situ testing (for example, the standard penetration test and cone penetration test). The digging of test pits and trenching (particularly for locating faults and slide planes) may also be used to learn about soil conditions at depth. Large-diameter borings are rarely used due to safety concerns and ...
Bed frames, also called bed steads, are made of wood or metal. The frame is made up of head, foot, and side rails. For heavy duty or larger frames (such as for queen- and king-sized beds), the bed frame also includes a center support rail. The rails are assembled to create a box for the mattress or mattress/box spring to sit on. Types include:
The CBR test is a penetration test in which a standard piston, with a diameter of 50 mm (1.969 in), is used to penetrate the soil at a standard rate of 1.25 mm/minute. Although the force increases with the depth of penetration, in most cases, it does not increase as quickly as it does for the standard crushed rock, so the ratio decreases.
A modern hospital bed at public hospital at Hong Kong Hospital beds per 1000 people 2013 [1] A hospital bed or hospital cot is a bed specially designed for hospitalized patients or others in need of some form of health care.

Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
Specific to marine structures, hospital piles (also known as gallow piles) are built to provide temporary support to marine structure components during refurbishment works. For example, when removing a river pontoon, the brow will be attached to hospital pile to support it. They are normal piles, usually with a chain or hook attachment.
