Cooling Devices in Laser therapy

Cooling devices and methods are now integrated into most laser systems, with a view to protecting the epidermis, reducing pain and erythema and improving the efficacy of laser. On the basis of method employed, it can be divided into contact cooling and non-contact cooling. With respect to timing of irradiation of laser, the nomenclatures include pre-cooling, parallel cooling and post-cooling. T...

Integrated cooling for optoelectronic devices

Active refrigeration of optoelectronic components through the use of thin film solid state coolers based on III-V materials is proposed and investigated. Enhanced cooling power comparing to the thermoelectric effect of the bulk material is achieved through thermionic emission of hot electrons over a heterostructure barrier layer. It is shown that these heterostructures can be monolithically int...

Induction of cooling with a passive head and neck cooling device: effects on brain temperature after stroke.

BACKGROUND AND PURPOSE Therapeutic hypothermia improves clinical outcome after cardiac arrest and appears beneficial in other cerebrovascular diseases. We conducted this study to investigate the relationship between surface head/neck cooling and brain temperature. METHODS Prospective observational study enrolling consecutive patients with severe ischemic or hemorrhagic stroke undergoing intra...

Physical Limits of Heat-Bath Algorithmic Cooling

Simultaneous near-certain preparation of qubits (quantum bits) in their ground states is a key hurdle in quantum computing proposals as varied as liquid-state NMR and ion traps. "Closed-system" cooling mechanisms are of limited applicability due to the need for a continual supply of ancillas for fault tolerance, and to the high initial temperatures of some systems. "Open-system" mechanisms are ...

External cooling in the management of fever.

Although physical methods of cooling are the treatment of choice for hyperthermia, their value in the treatment of fever remains uncertain. Methods involving convection and evaporation are more effective than those involving conduction for the treatment of hyperthermia. These same methods, combined with antipyretic medication, are preferable to immersion as treatment for fever in young children...
