An adaptive filter circuit for sampling a reflected voltage of a transformer of a power converter includes a first switch for receiving the reflected voltage, a resistor having a first terminal and a second terminal, the first terminal of the resistor being coupled to the first switch, a capacitor coupled to the second terminal of the resistor for holding the reflected voltage, and a second switch coupled to the resistor in parallel, wherein the resistor and the capacitor develop a filter for sampling the reflected voltage which is sampled without filtering by the filter in a first period during a disable period of a switching signal and also sampled with filtering by the filter in a second period during the disable period of the switching signal.
Abstract:
A hearing aid includes a magnetostrictive electroactive (ME) sensor that generates an electrical signal in response to a magnetic field or a mechanical pressure. In various embodiments, the ME sensor is used for cordless charging of a rechargeable battery in the hearing aid by generating an electrical signal in response to a magnetic field generated for power transfer, magnetic sound signal reception, and/or detection of user commands by sensing a magnetic field or a pressure applied to the hearing aid.
Abstract:
The present invention provides a control circuit for dimming LED lighting. The control circuit comprises a voltage divider, a controller and an adaptive bleeder. The voltage divider receives an input voltage from an input terminal to generate a dimming signal. The controller generates a switching signal in response to the dimming signal. The controller further generates a control signal in response to the input voltage. The adaptive bleeder receives the control signal and draws a bleeder current from the input terminal in response to the control signal.
Abstract:
A touch device and an operating method thereof are provided. The operating method includes the following steps. A plurality of data baseline values of the touch panel is calibrated and set during an initialization of a touch panel. A plurality of touch data is obtained after scanning the touch panel. A plurality of touch values corresponding to the touch panel is calculated according to the data baseline values and the touch data. A touch point is detected according to the touch values. When the touch data is complied with a re-calibration requirement, the data baseline values are re-calibrated and reset.
Abstract:
A method of presenting account payoff information to customers includes receiving electronic data relating to a plurality of customers and evaluating the data to determine a class to which each customer belongs. The method also includes preparing an account statement for each customer in a first class and for each customer in a second class. The account statement for each customer in the first class includes a standard message, and the account statement for each customer in the second class includes a detailed message. The method also includes transmitting an electronic file comprising the account statements for the plurality of customers to a statement generator. The standard message comprises a total time to pay off at least one hypothetical account balance at a hypothetical interest rate based on a first series of minimum payments. The detailed message comprises a total time to pay off an account balance of the customer at an interest rate of the customer based on a second series of minimum payments.
Abstract:
A receiver for an LCD source driver of an LCD panel includes a converter, a comparing circuit and a decoding circuit. The converter converts two pairs of differential current signals into two pairs of differential voltage signals. The comparing circuit is coupled to the converter for generating reference signals based on differences between the two pairs of differential voltage signals. The decoding circuit is coupled to the comparing circuit for generating data signals, clock signal, setting signals, and control signals based the reference signals.
Abstract:
A cooperative apparatus and a resource block allocation method thereof for use in a wireless network are provided. The wireless network comprises a plurality of femtocells. The cooperative apparatus groups the femtocells based on signal interferences between the femtocells. The femtocells with higher signal interferences are joined to the same femtocell group. The cooperative apparatus averagely allocates resource blocks to the femtocells in the same femtocell group, and randomly allocates resource blocks to different femtocell groups.
Abstract:

The nucleic acid modules include a receptor for advanced glycation end products (RAGE) signal sequence, a nucleic acid sequence encoding a tag and a multiple cloning sequence (MCS). Any membrane protein of interest can be cloned into the MCS for expression in cells. The nucleic acid modules can encode any type of tag, such as an epitope tag or affinity tag. The nucleic acid modules disclosed herein can be used to express any type of membrane protein and are particularly suited to the expression and tagging of Type I and Type III membrane proteins.
Abstract:
The present invention relates to a control method for idling anti-rollback of pure electric vehicle, which comprises the following steps: determining whether an anti-rollback control is needed by the current state of the vehicle or not with the vehicle controller according to the brake pedal, the handbrake device and the accelerator pedal; If needed, judging whether the working condition of the anti-rollback control is satisfied by the current states of the power battery, the motor controller, and the motor or not with the vehicle controller; If not satisfied, stopping the motor to output a torque; If satisfied, driving the motor to output the torque for the anti-rollback control. With this pure electric vehicle, the control method for idling anti-rollback of pure electric vehicle can be suitable for the pure electric vehicle, the pure electric vehicle uses the motor alone to drive the vehicle, therefore is very different from conventional cars in the control of the torque and the speed regulation, thus the present invention can be suitable for starting an electric vehicle at idle, prevents effectively an electric vehicle on a slope from rolling back, has a simple and quick processing procedure, and a stable and reliable performance, and lays a solid foundation for further development and application of the electric vehicle technology.
