Abstract: The invention relates to methods and systems for reading a memory cell and in particular, an STT MRAM. In one example, a system for reading a memory cell includes a sense path and an inverse path. A reference current is provided through the sense path and is sampled via a first sampling element in the sense path, and a cell current from the memory cell is provided through the inverse sense path and is sampled via a second sampling element in the inverse sense path. Subsequently, the memory cell is disconnected from the inverse sense path, the cell current is provided through the sense path, the reference source is disconnected from the sense path, and the reference current is provided through the inverse sense path. The output levels are then determined by the cell and reference currents working against the sampled reference and sampled cell currents.

Abstract: An electronic device includes a non-volatile memory having a plurality of memory cells, a memory controller, and an evaluator. The memory controller is configured to provide control signals to the non-volatile memory causing the non-volatile memory, or a selected memory section of the non-volatile memory, to be in one of a read state and a weak erase state, wherein the weak erase state causes the plurality of memory cells to maintain different states depending on different physical properties of the plurality of memory cells. The evaluator is configured to read out the plurality of memory cells and to provide a readout pattern during the read state, wherein the readout pattern that is provided after a preceding weak erase state corresponds to a physically unclonable function (PUF) response of the electronic device uniquely identifying the electronic device.

Abstract: An infinitely variable transmission includes a clutch, a brake and a first planetary gear set, including first and second components, and a double planetary gear set, including input and output components and additional third and fourth components. The first component receives power from an engine. The double planetary set sums mechanical power from the first planetary set and an infinitely variable power source (“IVP”). The third component receives mechanical power from a IVP. The second component directly transmits power to the input component. The clutch directly controls power transmission between the first and second components. The brake engages the fourth component to stop its rotation. The output component receives mechanical power directly from the input component and the fourth component. During operation of the engine, controlled actuation of the brake and the clutch causes the output component to be powered by the infinitely variable power source but not by the engine.

Abstract: A power train arrangement for a work vehicle with an engine may include an infinitely variable power source (“IVP”). An energy storage device may be configured to receive energy from the IVP for storage and to provide stored energy from the energy storage device to power one or more components of the IVP. A transmission may be configured to relay power from the engine and from the one or more components of the IVP to other components of the vehicle. A transient power event may be identified, during which a present operating state of the engine does not provide sufficient power for operations of the work vehicle. The energy storage device may be caused to provide stored energy to power the one or more components of the IVP source and thereby to provide power to the transmission.

The paper is passed in front of an in-line spectrophotometer or densitometer. The amount of image “show through” is measured and correlated to an amount of misregistration.

Abstract: Some embodiments of the present disclosure relate to a sense amplifier architecture that facilitates fast and accurate read operations. The sense amplifier architecture includes a folded cascode amplifier for its first sense amplifier stage, and a pre-charge circuit to establish a pre-charge condition for a senseline and a reference senseline of the sense amplifier. The pre-charge circuit and the folded cascode amplifier each include one or more cascode transistors of the same size and which receive the same bias voltage on a gate thereof. This architecture provides fast and accurate read operations in a relatively small footprint, thereby providing a good blend of cost and performance.

Abstract: According to one aspect of the invention, the circuit logic of an existing relay interlocking system is mapped onto a functionally equivalent circuit of electronic components. Semiconductor components that are functionally identical to the components of the relay circuit are thus preferably used. The circuit logic is created, for example, by transforming an interlocking table or track diagram into a logic circuit by means of an automatic compiler according to predefined rules.

Abstract: A printing system includes a first image applying component configured for applying one or more primary colorants to print media for rendering an image. A second image applying component is configured for applying a second colorant, such as black colorant, to print media for rendering an image. A first pathway conveys print media between the first image applying component and the second image applying component. A second pathway bypasses the first image applying component for conveying print media which is printed by the second image applying component. Where an image is to be rendered with the primary colorants and optionally also black, the print media is directed on the first pathway to both the first and second image applying components. Where an image is to be rendered only with black colorant, the print media may be directed to the second image applying component via the bypass pathway. In this way, during black printing, the first image applying component can be placed in a standby mode.
