Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. In some instances, as operating equipment heats up during operation, temperature changes of various portions of the operating equipment leads to changes in dimensions of such portions, leading to misalignment. Multiple sets of data representative of the operating equipment in multiple operating conditions can be used to determine an amount of misalignment due to thermal offsets. Hot and cold temperatures of the equipment can be used to calculate thermal growth of various portions of the equipment, which can be used to determine an amount a misalignment due to thermal offsets. Additionally or alternatively, image data representing the equipment can be used to observe changes in alignment between states.

In response to connection of a load of an IV curve tracer, the PV panel simulator produces an output current produced at a magnitude that settles from an initial state to approximately a steady state within a settling time period. The settling time period precedes a measurement time period during which the IV curve tracer measures the output current and voltage in the steady state.
A control system controls an inductor-inductor-capacitor (LLC) converter according to a switching method that tunes the output power of the LLC converter based on the required power to be supplied to an output load coupled to the LLC converter. The tuning of the output power is based in part on changing the duty cycle of a switching module. In addition, the output power is adjustable by changing a frequency of switching (e.g., a pulse width of the switching module output). The control system is capable of adjusting amplitude and changing rising slope of a current supplied to the output load by changing the duty cycle and pulse width of the switching. A piece-wise linear control method is achieved by controlling the duty cycle and pulse width differently when the input voltage is lower than a crossover voltage than when the input voltage is higher than the crossover voltage.

Probe device with spiral spring, rotating head and testing apparatus
A probe device for a rotating head has at least one support arm that is mounted so as to rotate around an axis of rotation, at least one probe that is joined to the support arm, and at least one spring element that can be supported on the rotating head and engages at the support arm and that is provided for exerting a force on the support arm, which, as a result of this force, experiences a torque with respect to the axis of rotation. The support arm has at least one mount, which is concentric with the axis of rotation, for the spring element, which, when arranged on the mount, is bent at least in part around the axis of rotation. As a consequence, centrifugal forces that act on the spring element when the rotating head is in operation have no influence on the tension of the spring element.

An electrical energy absorption and heat storage system absorbs electrical energy transferred during a calibration process of an electric vehicle charging station. The system includes a resistive load, which, in operation, receives electrical energy and converts the electrical energy into heat. The heat is transferred to and stored in one or more heat storage mediums and then dissipated. The heat storage mediums may include phase-change heat storage mediums, such as water, solid heat storage mediums, such as ceramic mass (e.g., alumina), or combinations thereof. The stored heat may be dissipated as steam, contained for later dissipation, or combinations thereof. Heat sinks, convection and conduction cooling may be employed to dissipate the stored heat. An energy status of the system, together with information regarding the characteristics of the calibration process, may be used to determine whether it is appropriate to use the system to absorb the heat of the calibration process.

A holder secured to a vertical column by a cross support holds an object in a fixed position. The holder includes a tube that can be secured to the cross support. A movable clip at a first end of the tube is configured to hold the object, e.g., a probe held in a calibration bath. The movable clip includes an aperture. When the movable clip is in an extended position, an object can be inserted into the aperture. When the movable clip moves toward a retracted position, the object is held within the aperture. A cap at the second end of the tube is coupled to the movable clip by a spring inside the tube. The movable clip exerts an adjustable holding force on the object by adjusting a number of turns of the spring between the cap and the movable clip. A central holding device may support multiple holders.

A temperature measurement system includes an optical resonator, a detector, and a computing subsystem. Light resonates in the optical resonator at resonant wavelengths that vary relative to a temperature in the optical resonator. The detector detects at least two resonant wavelengths of light output from the optical resonator. The computing subsystem determines the temperature of the optical resonator based at least in part on a mathematical operation on the at least two resonant wavelengths of the light output from the optical resonator. The mathematical operation may be a subtraction operation that determines a wavelength difference between two resonant wavelengths. In various implementations, the temperature of the optical resonator is determined based on a mapping of the wavelength difference to the temperature or based on an identified mode of the optical resonator and a mapping of the resonant wavelength to the temperature of the optical resonator in the mode.

TEMPERATURE MEASUREMENT SYSTEM AND METHOD USING MULTIMODE OF AN OPTICAL RESONATOR
A temperature measurement system includes an optical resonator, a detector, and a computer subsystem. Light resonates in the optical resonator at a resonant wavelength that varies relative to a temperature in the optical resonator. The detector detects a resonant wavelength in output light from the optical resonator. The computing subsystem receives a signal indicating the resonant wavelength, identifies a mode of the optical resonator based on a first temperature indication in or proximate to the optical resonator in a first temperature accuracy range, and obtains, based on the mode, a characteristic relationship indicative of a range of resonant wavelengths of the optical resonator relative to a range of temperatures in the optical resonator in the mode. Based on the resonant wavelength and a characteristic relationship, a second temperature indication in the optical resonator in a second temperature accuracy range having greater accuracy than the first temperature accuracy range is obtained.
