TL;DR: In this paper, a superconducting transition edge sensor is proposed, where the temperature of a superconding film is held constant by feeding back to its position on the resistive transition edge.
Abstract: A novel type of superconducting transition edge sensor is proposed. In this sensor, the temperature of a superconducting film is held constant by feeding back to its position on the resistive transition edge. Energy deposited in the film is measured by a reduction in the feedback Joule heating. This mode of operation should lead to substantial improvements in resolution, linearity, dynamic range, and count rate. Fundamental resolution limits are below ΔE=√kT2C, which is sometimes incorrectly referred to as the thermodynamic limit. This performance is better than any existing technology operating at the same temperature, count rate, and absorber heat capacity. Applications include high resolution x‐ray spectrometry, dark matter searches, and neutrino detection.

TL;DR: In this article, a generator operates under the control of a processor to apply power to each of the electrodes and the power has an associated phase angle and, within a time duration, a plurality of alternating on periods and off periods, one set of adjacent on-and off periods defining a duty cycle.
Abstract: A plurality of electrodes are positioned at the distal end of a catheter such that the electrodes may be positioned proximal biological tissue. A select number of the electrodes have a temperature sensing device associated with them for providing a temperature signal indicative of the temperature at the interface between the electrode and the tissue. A generator operates under the control of a processor to apply power to each of the electrodes. The power has an associated phase angle and, within a time duration, a plurality of alternating on periods and off periods, one set of adjacent on and off periods defining a duty cycle. The processor is programmed to determine the temperature at the electrode/tissue interface based on the temperature signals, compare the temperature to a target temperature and to adjust the power to the electrode accordingly. Such adjustments may comprise an increase or decrease in the duty cycle, a setting of the duty cycle to zero followed by an incremental increase in the duty cycle or a power interrupt.

TL;DR: In this article, an over-temperature control for heat lesion generation equipment in the case of neurosurgery is presented. But the system is a hybrid between a purely manually controlled radio frequency heating unit and a completely automatic controlling radio frequency unit, the latter being such that it automatically raises the radio frequency power and feedbacks on a set temperature to stabilize the final electrode temperature.
Abstract: The use of radio frequency currents to heat and destroy neurological tissues is well known in the field of neurosurgery and typically involves monitoring of the tissue temperature as it is being heated by an in-dwelling electrode. This patent deals with an apparatus and method which enables the operator of such apparatus to be in control of the rise of temperature and the increase in radio frequency power delivered to such electrodes, and yet also to pre-set a temperature and have control circuitry and other means to prevent the electrode temperature to exceed a set temperature point. We refer to this as an over-temperature control for heat lesion generation equipment in the case of neurosurgery. The system is a hybrid between a purely manually controlled radio frequency heating unit and a completely automatically controlled radio frequency unit, the latter being such that it automatically raises the radio frequency power and feedbacks on a set temperature to stabilize the final electrode temperature. The present invention retains the important position of the human operator in establishing the rise of temperature and yet affords the advantage of temperature stabilization at a fixed end point and thereby gives the benefits of a fully automatic control system to the added asset of safety and human control.
