摘要： A method for a mix mode driver to accommodate traces of different lengths includes sequentially shifting values of a data signal to a number of stages and sequentially amplifying the values of the data signal at least one stage. Depending on the length of trace for the data signal, the method further includes providing at least one amplifying coefficient to at least one stage and coupling a subset of the stages to an adder. The method finally includes outputting the data signal from the adder to the trace.

摘要： An in line fluid pressure regulating and pressure relief device having a regulator body with an axial bore therethrough with an inlet chamber conectable to a source of fluid under pressure and an outlet chamber connect able to a device requiring fluid under substantially constant pressure. A fluid pressure regulator located in the regulator body maintains fluid pressure at the outlet chamber at a constant predetermined level. A bleed piston located in the axial bore between the inlet chamber and to the pressure regulating means loses contact with said pressure regulating piston when the pressurized fluid source is removed from the regulator or drops below a certain level relieving substantially all pressure in said exit chamber and any attached device passively rendering the device inoperable.

摘要： The description relates to mobile device location. One example can identify global navigation satellite system (GNSS) satellites expected to be in line-of-sight of a mobile device. This example can detect differences between received GNSS data signals and expected GNSS data signals from the expected GNSS satellites. The example can also determine a direction from the mobile device of an obstruction that is causing at least some of the detected differences.

摘要： The described implementations relate to automatically performing device actions. One implementation can obtain a contextual value of a contextor. The implementation can decide, using a decision engine, whether to perform an action on a computing device based on the contextual value. In an instance when the decision engine decides that the action is to be performed, the implementation can perform the action on the computing device. The implementation can also update the decision engine using feedback related to the action. As a specific example, the action can be prelaunching an application before a user has requested to execute the application. Prelaunching the application can reduce application latency relative to waiting for the user to request to execute the application before launching the application.

摘要： A system for sensing an absolute two-dimensional position of an object having a two-dimensional target pattern thereon comprises a sensor and a controller. The sensor is for capturing an image of a subset of the target pattern. The controller is for generating a first image vector representing summations of rows of pixel values from the image, and a second image vector representing summations of columns of pixel values from the image. The controller is configured to determine an absolute two-dimensional position of the subset of the target pattern with respect to the origin of the target pattern based on the first image vector, the second image vector and target vectors that represent the target pattern.

摘要： A method for a mix mode driver to accommodate traces of different lengths includes storing in the mix mode driver a set of one or more control signals and coefficient signals for a trace length. The one or more control signals select a number of the stages to generate a variable amplitude data output signal. Each stage is operable to increase or decrease a data signal, and each of the coefficient signals determines the magnitude of increase or decrease of the data input signal by a stage. A method for operating the mix mode driver includes generating the variable amplitude data output signal with one or more of the stages, and providing the variable amplitude data output signal to a trace.
