Radiofrequency attenuator and method. The attenuator includes a pair of transparent windows. A chamber between the windows is filled with molten salt. Preferred molten salts include quarternary ammonium cations and fluorine-containing anions such as tetrafluoroborate (BF4−), hexafluorophosphate (PF6−), hexafluoroarsenate (AsF6−), trifluoromethylsulfonate (CF3SO3−), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N−), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N−) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3C−). Radicals or radical cations may be added to or electrochemically generated in the molten salt to enhance the RF attenuation.

摘要:
A system is provided for detecting the presence of a human in a compartment of a vehicle that comprises a pyroelectric sensor and a control coupled to the pyroelectric sensor. The pyroelectric sensor comprises a first sensing element and a second sensing element. The first sensing element is arranged in an opposed electrical connection with respect to the second sensing element whereby infrared radiation from a human moving within the compartment is selectively detected by one of the first sensing element and the second sensing element, thereby producing an output signal of the pyroelectric sensor. This output signal is received by the control, and the control generates a control signal indicative of detection of a human within the compartment.
摘要:
A user-controlled skylight window or the like in which the user can control the light transmitted through the skylight. A chromogenic filter is under automatic control of a control circuit. A user interface permits the user to set the control circuit for desired lighting. A mechanical shutter is likewise controlled to open or close the skylight under control of the user interface. A lamp within the skylight provides nighttime lighting under user control. The diffuseness of light transmitted through the skylight is improved by modifying the diffuseness of various components of the skylight including the filter. Uses of the filter in a variety of systems and with a variety of controls are disclosed.
摘要:
A transparent chromogenic panel in which color changes are selectively effectable over predefined areas comprises a pair of facing glass substrates each covered with a conductive layer divided into individual energizeable areas each provided with as set of busbars. An electrochromic electrode layer overlies at least one of the conductive layers. An insulating adhesive sealant spaces apart the substrates and insulates the busbar sets from each other and from exposure to the electrolyte and the electrochromic layer, so that each busbar set may be individually energizeable to effect a color change through a respective one of the individual areas. A passive layer is advantageously superimposed over one of the substrates, its color being chosen so that the color and the transmissivity of the passive layer accommodates the range of color change and transmissivity of the electrochromic layer to maintain the transmitted color of the panel in a warm or neutral shade.

Electrochromic devices and processes for preparing the same are provided which do not require a separate process step of ion intercalation by employing an electrochromically-inert reducing or oxidizing additive in the electrochemically active material or the electrolyte of the electrochromic devices.
摘要:
Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The above compositions can be incorporated in a variety of wound care products to provide antimicrobial properties.

The invention relates to polymeric coatings on proppants. These coatings have antimicrobial materials incorporated within these coatings. Preferably the antimicrobial materials have low water solubility. These antimicrobial agents are incorporated as particles whose surfaces are modified or these may also be incorporated within porous particles which are then added to the coating formulations. The antimicrobially active agents are incorporated in a fashion so that they can be released from these coatings in the environment of the proppants.
摘要:
Embodiments of the invention are directed to a composition having antimicrobial activity comprising particles comprising at least one inorganic copper salt; and at least one functionalizing agent in contact with the particles, the functionalizing agent stabilizing the particle in a carrier such that an antimicrobially effective amount of ions are released into the environment of a microbe. The average size of the particles ranges from about 1000 nm to about 4 nm. Preferred copper salts include copper iodide, copper bromide and copper chloride. Preferred functionalizing agents include amino acids, thiols, hydrophilic polymers emulsions of hydrophobic polymers and surfactants.
摘要:
An exterior reflective mirror element suitable for a vehicle includes a transparent glass substrate having a reflector and a visual indicator display disposed to the rear of the substrate. The visual indicator display may be part of a blind spot detection and display system of the vehicle wherein the visual indicator display is actuated to emit light responsive to a detection by a blind spot detection detector of the equipped vehicle of an overtaking vehicle in a side lane adjacent the side of the equipped vehicle. The visual indicator display includes at least a first indicator at a first location to the rear of the exterior reflective mirror element. A first portion of the reflector may be at least partially removed at the first location in order to establish an at least partially transmissive first portion of the exterior reflective mirror element at the first location.
