Abstract: A voltage regulator may derive current from a bias circuitry having a constant-transconductance. The bias circuitry may generate the bias current using three NMOS devices. The temperature coefficient of the bias current may be within a specified, desired range. The bias current may be mirrored to low-power regulator circuitry to bias a diode-connected transistor in the low-power regulator circuitry to operate in the strong inversion region. A ratioed current based on the output load current may be injected into a bipolar junction transistor (BJT) device to cause the gate-source voltage (VGS) of the diode-connected device to track the VGS of the output transistor of the voltage regulator, to ensure tighter load regulation.

Abstract: An electronic circuit may comprise an input stage powered by a supply voltage and configured to receive a reference signal. The circuit may further comprise an output stage powered by the supply voltage and coupled to the input stage, and configured to generate an error signal based on: the reference signal, and a feedback signal based on an output signal. The circuit may also include a pass transistor powered by the supply voltage and configured to generate the output signal based on the error signal. A capacitor coupled between the supply voltage and the output stage may increase the current flowing in the output stage, resulting in the output stage conducting current even during a rising edge of the supply voltage, preventing the output signal from reaching the level of the supply voltage during the rising edge of the supply voltage.

Abstract: A voltage regulator may comprise a regulator output configured to provide a regulated voltage, which may be controlled by an error amplifier based on the regulated voltage and a reference voltage. The error amplifier may control a source-follower stage to mirror a multiple of the current flowing in the source-follower stage into an internal pass device. A voltage developed by the mirror current may control an external pass device configured to deliver the load current into the regulator output. A first resistor may be configured to decouple a load capacitor coupled between the regulator output and reference ground, when the load current is below a specified value. A second resistor may be configured to create a bias current in the internal pass device even when the external pass device is close to cut-off region. A third resistor may be configured to counter the effects of negative impedance at the control terminal of the external pass device caused by the current-gain of the external pass device.

Each of the turbines has a blade set extending upward from the housing. Each blade set has a vertical axis extending upward in relation to the housing. Each of the turbines has a generator connected thereto, each generator being disposed in the housing, and having a rotor and a stator. Each turbine is rotatably mounted with respect to the housing, and mounted to the rotor so that they rotate together. Each housing has a positive connector and negative connector on each side of the respective unit. The units, when placed together, connect their respective poles, positive and negative, together completing a circuit. Therefore, one may connect multiple units together.

The conversion is performed using a firm exchange rate that is derived from a market exchange rate, but guaranteed for a period of time during which the transaction is anticipated to be completed.

Abstract: A level-shifter circuit configured to transfer data between two voltage supply domains may eliminate crowbar current while simultaneously providing a valid output signal. The level-shifter circuit may transfer a data signal between the two voltage domains using a latch that is capable of maintaining its output level—based on the destination supply rail—to correspond to the same state to which the level of the input signal—based on the originating supply rail—corresponds, even when the originating supply is decreased to a zero-volt state, or to a voltage equivalent to a low state. During normal operation, when both power supplies are available, the signal at the output of the latch, and hence at the output of the level-shifter circuit may toggle to always track the input signal. Thus, the level of the signal at the output of the level-shifter may always represent the same state (e.g.

Abstract: A circuit may comprise an amplifier powered by a first supply voltage, with a first input of the amplifier coupled to a stable reference voltage, and the output voltage of the amplifier provided as a designated supply voltage to an oscillator configured to produce a periodic signal having a specified frequency. The circuit may further include a control circuit coupled to a second input of the amplifier, to the output of the amplifier, and to ground, and configured to control the rate of change of the output voltage of the amplifier with respect to temperature. This rate of change may be specified according to a characterization of the oscillator over supply voltage and temperature, and may result in stabilizing the specified frequency across temperature. The periodic signal may therefore be unaffected by variations in the first supply voltage, and the amplitude of the periodic signal may be proportional to the stable reference voltage.

Abstract: A method processes the outputs of a discrete sensor in a computer system. An initial value mask is applied to each one of the offset bits in the output of the discrete sensor. An initial value is obtained for each one of the offset bits in the output of the discrete sensor according to the initial value mask. It is next determined whether or not the offset bits in the output of the discrete sensor includes both initialization offset bits and transition offset bits. If the offset bits include both initialization offset bits and transition bits, only the initialization bits of an incoming mask corresponding to the output of the discrete sensor are reset.

Abstract: A photocurable composition useful in preparing water-developable, solid printing plates is prepared by blending a urethane (meth)acrylate prepolymer with a complexing polymer based on poly(vinyl pyrrolidone) composition. The resulting composition is suitably formulated with additional photoactive (meth)acrylate monomers or oligomers and photoinitiator for casting or extrusion on a substrate to form a flexographic printing plate. Following UV exposure of the plate through a negative, unexposed areas can be removed by washing with aqueous media, to give a plate with a desirable relief image. The use of the aqueous washout solution as opposed to organic solvents minimizes pollution problems. The use of the complexing polymer significantly reduces the cold flow of the uncured plate and both increases toughness and reduces tack of the cured plate.

Abstract: Dense sintered parts of ceramic and/or metallic materials are formed using stereo photolithography. An initial flowable mixture of sinterable inorganic particles, photocurable monomer, photoinitiator and dispersant is flowed over a substrate and cured in a selective pattern. Subsequent layers of the mixture are flowed over the substrate and cured to build a three dimensional body. The body is then fired to produce a dense sintered part. Parts having in excess of 95% of theoretical density can be produced.

Abstract: An aqueous developable, photocurable composition and a method of improving solvent resistance and flexibility are disclosed. The composition comprises (a) an acid-containing copolymer having an acid ephr of at least 0.20 and (b) an acid-containing polymer suitable for flexibilizing the composition, which has at least one free ethylenically unsaturated group. It is preferable that either (a) or (b) or both are further reacted with a compound having a free ethylenically unsaturated group and a free acid reactive group, e.g. glycidyl(meth)acrylate. When the composition is formulated with an ethylenically unsaturated monomer and photoinitiator, the photocurable composition is especially suitable for use in an aqueous developable, flexible printing plate.
