30results about How to "Increasing lifetime" patented technology

An electrochemical sensor system and membrane and method thereof for increased accuracy and effective life of electrochemical and enzyme sensors.

A vapor deposition reactor and associated method are disclosed that increase the lifetime and productivity of a filament-based resistive-heated vapor deposition system. The reactor and method provide for heating the filament while permitting the filament to move as it expands under the effect of increasing temperature while limiting the expanding movement of the filament to an amount that prevents the expanding movement of the filament from creating undesired contact with any portions of the reactor.

A shift register includes several stages of shift register units. Each shift register unit includes a first level lifting unit, first level lowering unit, first driving unit and level controller. The first level lifting unit and first level lowering unit control the scan signal to be equal to a first timing signal and first voltage, respectively. The level controller includes an input unit, a charge storage unit, a second level lifting unit and a second level lowering unit. The input unit controls the third control signal to be equal to the first voltage at a node. The charge storage unit stores a voltage of the timing signal at the node. The second level lifting unit and second level lowering unit respectively control the second control signal to be equal to the third control signal and the first voltage to turn on and turn off the first level lowering unit.

A bipolar overvoltage battery pulser and method are provided that apply a positive pulse voltage and a negative pulse voltage alternately across the terminals of a battery. The object of the bipolar overvoltage battery pulser and method is to increase the cycle lifetime and capacity of storage batteries, such as lead acid batteries. The rise times for the leading edges of the positive pulses and for the trailing edges of the negative pulses are short compared to the ionic relaxation time in the electrochemical solution. Alternating between the positive and negative pulses gives each new pulse an equal starting condition without realizing any memory effect that otherwise may result if the last applied pulse was of the same polarity, which reduces the extent of overvoltage that may be applied to the battery and decrease the highest useable pulse cycling frequencies that could be achieved without experiencing pulse overlapping. The shape, type and timing of the pulses may be adjusted to create overvoltage pulses having high duration and amplitude.

A single-site catalyst is disclosed. The catalyst comprises a transition metal complex, an activator, and an allylic alcohol-containing polymer. The catalyst has high activity and great capability to incorporate higher α-olefins into polyethylene. The polyethylene produced has high molecular weight and low density.

Described herein are systems and methods for the generation of electric current and / or electric potential utilizing micro- or nano-channels and capillary flow, including fluidic or microfluidic batteries and electrochemical cells. The provided systems and methods use capillary force to promote fluid flow through micro- and nano-fluidic channels by evaporating fluid at one terminus of the channel, and the resulting fluid flow generates electric potential and or current. Advantageously, the described systems and methods remove the need for pressurized vessels or external pumps, increasing net energy generation and decreasing complexity and size of potential fluidic batteries.
