Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.

Abstract: An automatic tourniquet apparatus comprises a tourniquet cuff, a pressure transducer, a user interface, a patient hazard shield and a pressure regulator. The pressure transducer produces a cuff pressure signal. The user interface produces a reference pressure signal. The patient hazard shield is responsive to the cuff pressure signal and the reference pressure signal, and operable during a regulation time period to produce a patient hazard signal if, in one implementation, a current level of pressure in the tourniquet cuff is greater than the reference level of pressure by at least a predetermined overpressure limit. The pressure regulator is responsive to the patient hazard signal, and has a pressurizing element for increasing pressure in the cuff and a depressurizing element for decreasing pressure in the cuff. The pressurizing element is configured to be non-responsive if the patient hazard signal is produced.
