Abstract: The present invention discloses a sampling component comprising a sampling body that can be electrically heated and the outer surface of which has a wiping sampling area; and an insulated handle that is connected with one longitudinal end of the sampling body. The sampling component according to the present invention contacts directly the contacts of an external power supply after being disposed in a analysis chamber, the power supply is turned on to heat the sampling body so as to realize sample pyrolysis, and the power is turned off immediately after the sampling component is taken away. Thus, the power supply of the sampler can work discontinuously so that the power consumption of the system is reduced, meanwhile, the system malfunction caused by a long-term work of the sampling device under a high temperature can be avoided. The present invention further discloses a sampling device having said sampling component and an ion mobility spectrometer having the sampling device.

Abstract: A laser drive controller compensates for temperature-dependent effects of a temperature-sensitive laser. Temperature variations in the laser may be measured and/or predicted based on variable pulsed output. The controller may drive the laser to maintain temperature and/or to compensate for variations in temperature. The techniques may be applied to a laser scanner, scanned beam display, laser printer, laser camera, scanned beam imager, etc.

Abstract: A method comprises applying a first delay to a first signal that is ahead of a second signal in a series of signals and determining a first number of delay units that provides the first delay to change an order between the delayed first signal and the second signal that has a phase difference with the first signal. The method further comprises determining a similar number for any other pair of signals in the series of signals that have the phase difference. The method further comprises determining a maximum and a minimum from the obtained numbers and determining linearity of the seriels of signals based on a difference between the maximum and the minimum.
