摘要:
A conditioned vestibule, control system, and method are disclosed for use with a cold storage doorway that separates warm and cold sides. A heater warms an air stream discharged across the doorway by the vestibule. A control unit operates the heater to maintain an air stream temperature. The control unit continuously monitors the air stream temperature and operates the heater to maintain the air stream temperature in a non-saturated state based on a humidity ratio. One embodiment calculates first and second temperatures based, respectively, warm and cold side tangent lines to a psychrometric saturation curve and based on the humidity ratio. The tangent lines are based on humidity and temperature sensed on the warm and cold sides. The air stream is warmed to at least the greater of the first and second temperatures. One embodiment controls air flow to adjust the humidity ratio to more efficiently operate the vestibule.

Processes for alkylating hydroxyaryl compounds by reacting a hydroxyaryl with at least one olefin of a complex hydrocarbon stream. The complex hydrocarbon stream preferably comprises a fraction of a cracked hydrocarbon feed stream or the reaction products of a dehydrogenation of a paraffinic feedstock. The olefin of the complex hydrocarbon stream is preferably a branched olefin, e.g., isobutylene or isoamylene. The alkylated compositions are suitable for forming liquid phosphite compositions.

The number of ways in an N-way set associative sequential cache is modulated to trade power and performance. Way selection is restricted during the allocation based on address so that only a subset of the N-ways is used for a range of addresses allowing the N-ways that are not in use to be powered off.

A printing line is provided for producing a retro-reflective material which comprises at least one first screen printing stage. The or each first stage comprises a screen with a shaped stencil, for applying a layer of adhesive to a substrate in a pattern defined by the stencil or stencils. The printing line also comprises a second screen printing stage which comprises a screen with a shaped stencil having a shape within the boundaries of, or the same as, the adhesive pattern generated by the or each first stage, for applying a layer of retro-reflective elements, for example micro-beads, to the layer of adhesive.

Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed. A system for the application of microwave energy to a tissue includes a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue. The applicator includes one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to the tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue includes a first layer and a second layer, the second layer below the first layer. The controller is configured so that the system delivers energy such that a peak power loss density profile is created in the second layer.

A flexible, lightweight radiation absorbing sheet or shield includes heavy metal particles in one layer and mid-atomic number particles in another layer, the layer that will adjacent to the patient. The shield is particularly intended for protection of the wearer and others from radiation emanating from a therapeutic source positioned within the patient's body. With the disclosed multi-layer shield construction, backscattered radiation off the heavy metal particle layer, affecting the patient's adjacent tissue, is minimized.

A firefighter's helmet comprising an inner protective shell configured to be worn on its own as a helmet and an outer protective shell configured to be fitted over the inner shell and realizably retained thereon, a retaining mechanism for retaining the inner shell in the outer shell, wherein the retaining mechanism is moveable by a user whilst wearing the inner shell between a first position in which the retaining mechanism engages a said shell substantially to prevent relative movement between the two shells, and a second position in which the retaining mechanism permits relative movement of the shells whereby allowing the donning or doffing of the outer shell by the user.
摘要:
A method of manufacturing an integrated light emitting diode display is provided. In one exemplary embodiment, the method includes the step of biologically forming a pn junction over a substrate, the pn junction capable of emitting a light having a predetermined color upon the application of energy thereto. In another exemplary embodiment, a method of manufacturing a light emitting diode is provided. The method includes depositing a biological material over the substrate, the biological material having an affinity for a pn junction material, and exposing the deposited biological material to the first pn junction material to form a doped area of a pn junction. In still another exemplary embodiment, a light emitting diode is provided. The light emitting diode includes a substrate and a biologically formed pn junction disposed over the substrate, wherein light having a predetermined color is emitted upon application of energy to the pn junction.
