A Ferroelectric tunnel FET switch as ultra-steep (abrupt) switch with subthreshold swing better than the MOSFET limit of 60 mV/decade at room temperature combining two key principles: ferroelectric gate stack and band-to-band tunneling in gated p-i-n junction, wherein the ferroelectric material included in the gate stack creates, due to dipole polarization with increasing gate voltage, a positive feedback in the capacitive coupling that controls the band-to-band (BTB) tunneling at the source junction of a silicon p-i-n reversed bias structure, wherein the combined effect of BTB tunneling and ferroelectric negative capacitance offers more abrupt off-on and on-off transitions in the present proposed Ferroelectric tunnel FET than for any reported tunnel FET or any reported ferroelectric FET.

A lighting device includes a lighting unit which controls a current being supplied to a load, in which light emitting modules, each having one or more semiconductor light emitting elements connected in series, are connected in parallel, to be a constant current; a current detector which detects a current flowing through one of the light emitting modules; and an abnormality detector which compares a detected value from the current detector with an upper limit and a lower limit of a predetermined current range to detect an abnormality in the load. The abnormality detector detects the abnormality in the load if the detected value from the current detector is larger than the upper limit or smaller than the lower limit, and if the abnormality in the load is detected, the lighting unit reduces the current being supplied to the load.

A method and apparatus are described which reduce the presence of an unwanted signal. According to one embodiment, a first signal is provided from a desired location that includes an unwanted signal while a second signal is provided from an alternate location (e.g., one where the unwanted signal is less of a proportion of the total signal). The first and alternate signals are provided to respective signal processors. A level for a selected frequency band of the first and alternate signals is adjusted so that an increase in one results in a decrease in the other. Doing so allows the frequency band that includes the unwanted signal to be reduced in the desired first signal and filled in with a similar frequency band from the alternate signal.

Improved transient response times are obtained while maintaining low emissions with a low pressure EGR system through methods for quickly obtaining a desired oxygen concentration for charge-air to be used for combustion. Under a first method, fuel quantity in the main combustion event is controlled in the combustion process to produce exhaust around a relatively constant target exhaust oxygen concentration value. By keeping the exhaust oxygen concentration levels at a relatively constant value, lag time in waiting for low pressure EGR valve adjustments during transients may be avoided, and the system's air handling response to meet transients may be paced solely by adjusting the mass of air to be supplied (i.e. boost response). Under a second method, a multiple-stage combustion process is utilized, in which fuel feed is controlled in a small, preliminary HCCI-type combustion event in order to produce a target oxygen concentration of charge-air to be used for the second, main combustion event. Under a third method, exhaust rebreathing is used to produce a target oxygen concentration of charge-air to be used for combustion.

A biometric authentication system, authentication client terminal, and biometric authentication method are provided to reduce an expected value of the number of inputs of biometric data for authentication, while effectively preventing forgery. In a biometric authentication system, prior probabilities of enrolled users u_n and non-enrolled user u₀ are previously set. 1:N matching is performed between feature data of a claimant v and matching feature data. The matching score is calculated for each enrolled user u_n. A ratio of the likelihood v=u_n to the likelihood v≠u_n is calculated for each enrolled user u_n using the calculated matching scores. Posterior probabilities of the enrolled users u_n and non-enrolled user u₀ are calculated, using the likelihood ratios, and the prior probabilities of both the enrolled users u_n and the non-enrolled user u₀. Then, determination is made by comparing each posterior probability with a first threshold.

To effect power control of a power amplifier 2 having three amplifier stages 3, 4 and 5 used to amplify input signals modulated in accordance with a variable envelope modulation scheme, there is used a power amplifier 2 having a gain which reduces as the supply voltage to the power amplifier 2 reduces, and the output power P_OUT of the power amplifier 2 is controlled by regulation of the supply voltage V_S. Taking advantage of the reduction in gain of the power amplifier 2, it is ensured that, in respect of each respective amplifier stage 3, 4 and 5 and at each respective value of the supply voltage in the voltage control range, the output power P_OUT of the respective amplifier stage 3, 4 and 5 is less than the saturation output power P_SAT of the respective amplifier stage 3, 4 and 5. As a result, distortion of the signal is reduced. The power control technique improves efficiency over known techniques of backing off the output power and using a variable gain amplifier stage to control the output power.

An in situ soil remediation system may be used to remove or reduce levels of mercury contamination within soil. The soil remediation system may also remove or reduce levels of other contaminants within the soil. Mercury may be vaporized within the soil by a heating system. The vaporized mercury may be removed from the soil by a vacuum system. The vaporized mercury may pass through heated risers that elevate the vaporized mercury. After the vaporized mercury passes from the heated risers, the vaporized mercury may be allowed to cool, condense, and flow downward to a treatment facility. Removing mercury from the soil as a vapor may provide an economical, safe, and efficient way to remediate mercury contaminated soil.
