Heat-retaining mattress for temperature control in surgery.
to eight and there are two other buttons, nine and zero, so that a man can supply numerical data such as his age and check number. There is also a button he can use to cancel a wrong answer and a button which switches on a microphone and tape-records any verbal comments that may be necessary. The sets of pictures and words are recorded on film and projected on to the screen by the optical devic...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولTemperature-gated thermal rectifier for active heat flow control.
Active heat flow control is essential for broad applications of heating, cooling, and energy conversion. Like electronic devices developed for the control of electric power, it is very desirable to develop advanced all-thermal solid-state devices that actively control heat flow without consuming other forms of energy. Here we demonstrate temperature-gated thermal rectification using vanadium di...
متن کاملConductive heat exchange with a gel-coated circulating water mattress.
The use of forced-air warming is associated with costs for the disposable blankets. As an alternative method, we studied heat transfer with a reusable gel-coated circulating water mattress placed under the back in eight healthy volunteers. Heat flux was measured with six calibrated heat flux transducers. Additionally, mattress temperature, skin temperature, and core temperature were measured. W...
متن کاملEsophageal Heat Transfer for Patient Temperature Control and Targeted Temperature Management
Controlling patient temperature is important for a wide variety of clinical conditions. Cooling to normal or below normal body temperature is often performed for neuroprotection after ischemic insult (e.g. hemorrhagic stroke, subarachnoid hemorrhage, cardiac arrest, or other hypoxic injury). Cooling from febrile states treats fever and reduces the negative effects of hyperthermia on injured neu...
