Abstract: 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.

Abstract: 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.

The wax can be selected from a paraffin wax, a microcrystalline wax, and mixtures and combinations thereof. The mixture can have a carbon loading of approximately 10 to 50 wt. %, based on total weight of the mixture. Methods for protecting a current collector from material degradation are also described herein.

Abstract: The present invention describes a device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate left cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic valves which simulate mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a control unit and sensors, one or more parameters such as flow rates, fluidic pressure, and heart rate may be automatically controlled, using feedback loop mechanisms to adjust parameters of the hydraulic system simulate a wide variety of cardiovascular conditions including normal heart function, severely diseased or injured heart conditions, and compressed vasculature, such as hardening of the arteries.

In conjunction with the interaction of synthetic mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a remote handheld electronic controller and manual adjustments from a main control panel, the air pressure level, fluidic pressure, and heart rate is controlled to induce contractions that simulate a wide variety of heart conditions ranging from normal heart function to severely diseased or injured heart conditions.

Abstract: The present invention provides a system and method for firearm storage; and more particularly, a safe and secure handgun mini-vault apparatus for a loaded handgun that allows an authorized user rapid, unobstructed and effortless access to the handgun. The handgun mini-vault system of the present invention not only provides for relative ease of assembly and aesthetically appealing appearance, it also permits access to the handgun without the need to manually manipulate a locking device. The locking system of the present invention utilizes RFID technology to allow authorized users to open the mini-vault by simply waiving an RFID chip in proximity to the mini-vault interrogator.

Abstract: 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.

Abstract: There is provided a photosensitive composition including a polyimide or polyimide precursor. The polyimide and polyimide precursor of the present invention includes a group of a first acid-cleavable group, a first base-cleavable group or a first thermally-cleavable group, and another group of a hydrophilic group, or a protected hydrophilic group by a second acid-cleavable group, a second base-cleavable group, or a crosslinkable group.

Abstract: 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.

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.
