In an electrical machine which has unidirectional excitation applied to its windings, the mean values of voltage and current can be computed from the instantaneous phase voltage and current by the use of, for example, low-pass filters (in either the analogue or digital domain). The value of winding resistance can then be calculated by dividing the mean voltage by the mean current. This avoids the cost, fragility and potential inaccuracy of conventional temperature sensors, and provides the controller with an ongoing estimate of winding temperature. |

An LED-based lighting system is operated with a time-based process. The LEDs are first turned on by energizing the system at full power. After a predetermined time period, which is selected so that the junction temperature of the LEDs does not reach a critical temperature, the current supply is ramped down to a steady-state supply. The steady-state current is maintained as long as the light is turned on. When the light is turned on the next time and the LEDs have not cooled down all the way, as determined by the time that has expired since the LEDs were last lit, the full-power time period is shortened accordingly. |

An accurate, cost-efficient temperature sensor may be integrated into an integrated circuit (IC) using common materials as the IC's interconnect metallization. The temperature sensor may include an impedance element having a length of metal made of the interconnect metal, a current source connected between a first set of contacts at opposite ends of the impedance element, and an analog-to-digital converter connected between a second set of contacts at opposite ends of the impedance element. The temperature sensor may exploits the proportional relationship between the metal's resistance and temperature to measure ambient temperature. Alternatively, such a temperature sensor may be used on disposable chemical sensors where the impedance element is made of a common metal as conductors that connect a sensor reactant to sensor contacts. In either case, because the impedance element is formed of a common metal as other interconnect, it is expected to incur low manufacturing costs. |

Apparatus and method for control of epitaxial growth parameters, for example during manufacture of light emitting diodes (LEDs). Embodiments include PL measurement of a group III-V film following growth while a substrate at an elevated temperature is in a transfer chamber of a multi-chamber cluster tool. In other embodiments, a film thickness measurement, a contactless resistivity measurement, and a particle and/or roughness measure is performed while the substrate is disposed in the transfer chamber. One or more of the measurements performed in the transfer chamber are temperature corrected to room temperature by estimating the elevated temperature based on emission from a GaN base layer disposed below the group III-V film. In other embodiments, temperature correction is based on an absorbance band edge of the GaN base layer determined from collected white light reflectance spectra. Temperature corrected metrology is then used to control growth processes. |

In a plasma display, a drain of a first transistor is connected to a scan electrode, and a source of the first transistor is connected to a power source supplying a first voltage. First and the second resistors are connected in series with the scan electrode and the power source. A scan electrode driver turns on the first transistor during a reset period to decrease a voltage of the scan electrode. A scan electrode driver senses the voltage of the electrode from a voltage divided by first and second resistors connected in series between the electrode and the power source. Upon the voltage of the scan electrode becoming a second voltage which is higher than the first voltage, the scan electrode driver turns off the first transistor to maintain the voltage of the scan electrode at the second voltage. In an address period, a scan electrode driver supplies the first voltage to the scan electrode of a light emitting cell. At least one resistor of the first and second resistors is a variable resistor in which resistance varies as the temperature of the Plasma Display Panel (PDP) varies, such that the plasma display can perform steady operation. |
