A phototherapy device includes a clothing item. Illuminators are secured to the clothing item and arranged to illuminate at least a portion of a patient wearing the clothing item. The illuminators include light emitting diodes (LEDs) mounted on at least one flexible printed circuit board (PCB). A temperature sensor is secured to the clothing item and positioned to measure a temperature proximate to the patient wearing the clothing item. A control circuit is connected to receive the temperature from the temperature sensor and operative to turn off the illuminators responsive to the temperature exceeding a maximum permitted temperature.

Methods for the production of carbon black using an extender fluid(s) are provided as well as methods to control one or more particle properties of carbon black utilizing extender fluids and other techniques.

Method for producing carbon black using an extender fluid

An emergency medical device () (e.g., an external defibrillator/monitor) employing an emergency medical subsystem () for executing an emergency medical procedure (e.g., a monitoring subsystem () and a therapy subsystem ()), and an emergency medical controller () for controlling an activation of the emergency medical subsystem (). The subsystem () includes one or more operational components (). In operation, the controller () conditionally actuates a device readiness indicator () (e.g., auditory or visual) indicative of an operational readiness of the operational component(s) (), and conditionally actuates a failure warning indicator () (e.g., auditory or visual) indicative of a pending failure of the operational readiness of the operational component(s) (). The failure warning indicator () may be actuated based on a predictive failure analysis of a premature degradation of the operational component(s) (), a repeated occurrence of error conditions of the operational component(s) () (particularly recoverable error conditions), and a shortened reliable life of the operational component(s) ().

A defibrillator produces a biphasic defibrillation pulse waveform with adjustable tilt for the second phase. The tilt of the second phase of the biphasic waveform can be controllably adjusted by selectively switching a current path which bypasses the patient during delivery of the second phase of the pulse. The inventive biphasic waveform can be delivered by a defibrillator with a single capacitance.

A defibrillation circuit comprising a gas discharge tube and a light source arranged to pre-energize the gas discharge tube in order to provide predictable breakdown conditions of the gas discharge tube. The gas discharge tube may be used as an overvoltage protection device for the defibrillation circuit or for certain parts of the defibrillation circuit. An overvoltage protection device for medical devices is also described. The overvoltage protection device comprises a gas discharge tube and a light source arranged to pre-energize the gas discharge tube in order to provide predictable breakdown conditions of the gas discharge tube.
