摘要:
A lighting system distinguishes between light from natural and manmade sources to prevent the system's light source from being inadvertently deactivated due to light received from manmade light sources. A sensor converts received light into electrical energy. The system light source and/or some other external light source can emit light with a modulation. The system includes a modulation detector that can detect the modulation in the electrical energy received from the sensor. A system controller selectively adjusts the flow of electrical energy to the system light source responsive to the electrical signals from the sensor. The controller adjusts the flow of electrical energy in response to the non-modulated component of the electrical signals from the sensor. The controller does not adjust the flow of electrical energy in response to the modulated component of the electrical signals from the sensor.

A solid-state lighting device for illuminating a predetermined area having a width and length includes a reflector having at least one cavity. At least one edge emitting solid-state light-emitting device is positioned relative to the cavity of the reflector. The cavity includes an inner curved surface terminating at an edge proximate the solid-state light-emitting device. The inner curved surface has a curvature such that a light intensity of the device has a sharp drop-off in intensity at a boundary of the width and a slowly attenuating light at a boundary of the length.

Photosensitive polyimide compositions include a photosensitive additive and a polymer comprising a repeating unit represented by the following formula (I): wherein R1 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R2 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R3 represents hydrogen or an organic group comprising a hydrophilic group, an acid-cleavable group, a base-cleavable group, a cross-linkable group, or combinations thereof, and h represents an integer of 1 or more. The photosensitive compositions may be formed by combining a precursor polymer with a processing solvent, followed by a relatively low-temperature cyclization process in which the precursor polymer is converted to the final polymer. The resulting polyimide may be separated from the solution and purified. It may then be combined with a casting solvent and a photosensitive additive.

A system and method of intubating a patient includes an intubating body. A user-control at or associated with the proximal end of the body allows both display of patient oral cavity anatomy and control of orientation of a stylet guide at or near the distal end of the body. The combination assists a user to effectively intubate the patient even if the patient has difficult anatomy.

An bottle warming apparatus may be provided. The apparatus may include a bottle for storing food and fluids. The bottle may include a recessed portion and indentations positioned on opposite sides of the bottle. Additionally, the apparatus may include a bottle housing configured to receive the bottle. The apparatus may also include a heating element that is positionable into the recessed portion of the bottle. Furthermore, the apparatus may include a pressure-sensitive switch that activates the apparatus when the bottle exerts enough pressure against the switch as the bottle is positioned into the bottle housing. Heat may be generated by the heating element when the apparatus is activated and be utilized to warm the bottle. The apparatus may further include a temperature sensor for measuring a temperature of the bottle. A signal may be transmitted to instruct the apparatus to deactivate when an optimal temperature is reached.

Photosensitive polybenzoxazine compositions include a photosensitive additive such as an o-diazoquinone and a polymer comprising a repeating unit represented by the following formula (I) wherein R1 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R2 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R4 comprises a hydrophilic group, a hydrophilic group protected by an acid-cleavable group, a hydrophilic group protected by a base-cleavable group, a cross-linkable group, or combinations thereof, and i represents an integer of 1 or more. The photosensitive compositions may be formed by combining a precursor polymer with a photosensitive additive and a solvent, patterning the precursor polymer, and heating the precursor polymer at a thermal processing temperature in a range of from about 180° C. to about 300° C. to convert the precursor polymer into the final polymer.
