A method of driving regulation for bipolar transistors in electronic ballast is provided. The method may include: sensing voltage at midpoint of half bridge of the transistors; producing a reference time signal according to a sync signal from a timer; producing actual time interval in this cycle by comparing rising edge of the voltage at midpoint of the half bridge of the transistors with rising edge of a driving signal for the transistors in upper bridge arm in each switching cycle; comparing the actual time interval with the reference time signal to determine pulse width of the driving signal; regulating, in which the driving signal in this switching cycle is prolonged relative to the driving signal in previous switching cycle if the actual time interval is larger than the reference time signal, while the driving signal in this switching cycle is shortened relative to the driving signal in previous switching cycle if the actual time interval is smaller than the reference time signal.

A method and apparatus are described for fabricating a low-pin-count chip package (701) including a die pad (706) for receiving an integrated circuit device and a plurality of connection leads (702) having recessed lead ends (704) at the outer peripheral region of each contact lead. After forming the package body (202) over the integrated circuit device, unplated portions (104) of the exposed bottom surface of the selectively plated lead frame are partially etched to form recessed lead ends (302) at the outer peripheral region of each contact lead, and the recessed lead ends are subsequently re-plated (402) to provide wettable recessed lead ends at the outer peripheral region of each contact lead.

An iridium oxide (IrOx) nanowire neural sensor array and associated fabrication method are provided. The method provides a substrate with a conductive layer overlying the substrate, and a dielectric layer overlying the conductive layer. The substrate can be a material such as Si, SiO2, quartz, glass, or polyimide, and the conductive layer is a material such as ITO, SnO2, ZnO, TiO2, doped ITO, doped SnO2, doped ZnO, doped TiO2, TiN, TaN, Au, Pt, or Ir. The dielectric layer is selectively wet etched, forming contact holes with sloped walls in the dielectric layer and exposing regions of the conductive layer. IrOx nanowire neural interfaces are grown from the exposed regions of the conductive layer. The IrOx nanowire neural interfaces each have a cross-section in a range of 0.5 to 10 micrometers, and may be shaped as a circle, rectangle, or oval.
摘要:
Methods of using genetically-transformed plants in the phytoremediation of lead are described. Unlike many organisms in which only 10-kDa ACBPs have been identified, there exists a family of six ACBPs in the model plant Arabidopsis. Other than a function in mediating the transfer of acyl-CoA esters in plant lipid metabolism, all six Arabidopsis ACBPs can bind the heavy metal lead and are therefore applicable for phytoremediation. These methods of phytoremediation will provide a cheap, simple and efficient method in the removal of contaminating lead from soil/water/environment by the growth of the ACBP-overexpressing genetically-transformed plants in the contaminated environment. There is also provided a method to remove lead from contaminated water.

A method for transmitting data packets and a corresponding converter are disclosed. The method includes: receiving a packet, which is sent by a source host using a Path Maximum Transmission Unit (PMTU) value supported by the source host as a Maximum Transmission Unit (MTU) value; sending an error information with a PMTU value of a translator to the source host if the PMTU value of the translator is smaller than the packet sent by the source host; receiving a packet, which is resent by the source host using a redetermined PMTU value as the MTU value, and sending the packet resent by the source host to a destination host; wherein the redetermined PMTU value is determined according to the PMTU value of the translator. The embodiments of the present invention ensure the maximum throughput of the network in the network transmission process, prevent packet loss, and improve the data transmission performance.
