Abstract: A controllable thermal warming device for delivering heat to an object by radio frequency signal. The controllable thermal warming device may include a thermal ink heating element comprising a substrate and a conductive ink fixedly disposed on the substrate, a power source operatively coupled to the conductive ink, the power source adapted to deliver a voltage to the conductive ink to cause the conductive ink to radiate heat, a controller operatively coupled to the power source and the conductive ink, the controller adapted to control the voltage delivered to the conductive ink and to detect an operating characteristic of the conductive ink and adjust the voltage in response to the operating characteristic, and means for controlling the controller by radio frequency. The controllable thermal warming device may also include a sensor to provide the operating characteristic to the controller.

Abstract: A portable controllable thermal warming device including a thermal ink heating element having a conductive ink pattern comprised of interconnected lines in a definite pattern fixedly disposed on a substrate, a controller operatively coupled to a power source and the conductive ink pattern, the power source adapted to deliver a voltage to the conductive ink pattern causing the conductive ink pattern to radiate heat, the controller adapted by way of a sensor to control the voltage delivered to the conductive ink pattern and adjust the voltage in response to the operating characteristic and the means for controlling the voltage by a wire link or a wireless remote signal.

Abstract: An improved apparatus for ultrasonic nebulization of liquid samples or suspensions in which the piezoelectric transducer is protected from chemical attack and erosion. The transducer is protected by being bonded to the inner surface of a glass plate which forms one end wall of a first hollow body provided with apparatus for circulating a fluid for cooling and stabilizing the transducer. The glass plate, which is one-half wavelength in thickness to provide an acoustically coupled outer nebulizing surface, seals an opening in a second hollow body which encloses an aerosol mixing chamber. The second body includes apparatus for delivering the sample solution to the nebulizing surface, a gas inlet for providing a flow of carrier gas for transporting the aerosol of the nebulized sample and an aerosol outlet.
