The method for modeling a dosing regimen for a medicament includes providing a system having at least two biocompartments. The method determines steady state levels in each of the biocompartments. After that, the method provides for modifying values to calculate an amount of at least one protein in one of the biocompartments to which the protein is being transported. Next, the method calculates and integrates a weighted value of the protein to find a weighted area under the curve. Then, the method calculates and integrates a non-drug value of the protein to find a non-drug area under the curve. Finally, the method evaluates one or more dosing regimens by comparing the weighted area under the curve and the non-drug area under the curve of the protein to determine a net effect of the drug over the time period.

The present invention generally teaches systems and methods for creating appliance signatures based upon whole house composite load profiles. Methods may includes steps such as identifying primitive elements including transients and absolute steady state levels; clustering the primitive elements along multiple dimensions to form impulses; combining impulses to form simple bundles; combining simple bundles with each other or impulses to form complex bundles; and determining specific appliance signatures that substantially match the complex bundles. Methods may also include steps such as determining transitions within the whole house composite load profile; determining household specific appliance state machines for each appliance in the household; and disaggregating the whole house composite load profile into individual appliance energy loads by assigning the determined transitions to the determined household specific appliance state machines.

This disclosure describes systems, methods, and apparatuses for extinguishing electrical arcs in a plasma processing chamber. Once an arc is detected, the steady state voltage provided to the plasma processing chamber can be reduced, and the current being provided to the chamber decays below a steady state value as the arc is extinguished. When the current falls to or below a current threshold, the voltage can be ramped back up bringing the voltage and current back to steady state values. This technique enables power to return to a steady state level faster than traditional arc mitigation techniques.

Non-volatile storage elements are programmed using counter-transitioning waveform portions on neighboring word lines which reduce capacitive coupling to a selected word line. In one approach, the waveform portions extend between pass or isolation voltages of a boosting mode, which are applied during a programming pulse on the selected word line, and read voltages, which are applied when verify pulses are applied to the selected word line to verify whether the storage elements have been programmed to a desired programming state. The waveform portions reduce the net voltage change which is coupled to the selected word line. The selected word line can reach a reduced, steady state level sooner so that the verify pulses can be applied sooner, thus reducing the overall programming time.

A method for reducing bit errors in an analog to digital converter having an array of comparators. The outputs of first and second comparators are received as in inputs to an Exclusive OR gate. The first and second comparators are separated in the array by a third comparator. The output of the Exclusive OR gate is used to determine if the third comparator is in a metastable condition. If the third comparator is in a metastable condition, the bias current of the latch circuit of the third comparator is increased to increase the rate at which the third comparator transitions to a steady state.

The invention discloses a brain-controlled input method based on steady-state visual evoked potential and motor imagination. In order to overcome the problem of singleness and limitation of the function realization of the existing control method, the method comprises the following steps: 1) collecting EEG signals; (1) generating EEG signals; (2) EEG signal acquisition; 2) on-line EEG signal processing; 3) control that virtual keyboard to realize the intelligent typing function: the virtual keyboard interface is divide into: (1) a display interface: a. A character display area, wherein the character display area is used for displaying the input character; (b) vocabulary association area: that vocabulary association area can be use for users to quickly select character-related vocabulary andcan be selected whether to open or not; (2) Visual evoked input interface: All the 13 flashing keys in the visual evoked input interface can stimulate human brain to produce SSVEP potential. The movement of virtual keys is controlled by left and right hand movement imagination, and the selection of virtual keys is controlled by stimulating cerebral cortex to produce SSVEP signal by fixing virtualkeys.

The invention discloses a transient state event and steady state event monitoring method during an electric energy classification metering process. The transient state event and steady state event monitoring method is suitable for being used for a non-intrusive load electric energy monitoring system, and is used to monitor a starting point of a transient state event and a starting point of a steady state event, and is used to solve problems of a classification metering system such as identification precision, calculation speed, and management efficiency. Data acquisition equipment and a virtual device are used to design a platform, and a voltage signal and a current signal of a user side are acquired, and then a power value is calculated to form a power sequence. The quantification and the median filtering preprocessing of the acquired data are carried out to reduce influences of spike noises and isolated noise points on the measurement of the starting point of the transient state event and the starting point of the steady state event. The starting point of the transient state event is acquired by adopting a transient state event starting point calculation method, and the starting point of the steady state event is acquired by adopting a steady state event starting point calculation method, and the operation state of the load is determined. The transient state event and steady state event monitoring method has advantages of high precision, easy realization, and applicability in fields such as high-level measurement system of intelligent power grid and electric energy demand side management.

An Off Chip Driver (OCD) having a high, a low and a high impedance (Hi-Z) state. The OCD includes an up-level pre-drive, a down-level pre-drive and a driver. The driver mirrors current in the up-level pre-drive and down-level pre-drive. Both pre-drive circuits have an unbalanced input-dependant delay to quickly turn off / on the on and off driver devices and, after a delay, reduce the drive on the turned on device to a steady state level. The delay may have a fixed length set by an inverter chain or may be dependent upon output voltage.
