Abstract: Apparatus and methods for current sensing in switching regulators are provided. In certain implementations, a switching regulator includes a switch transistor, a replica transistor, a sense resistor, and a current sensing circuit. The drain and gate of the switch transistor can be electrically connected to the drain and gate of the replica transistor, respectively. The current sensing circuit can generate an output current that varies in response to a sense current from a source of the replica transistor. Additionally, the current sensing circuit can sink the sense current when the sense current flows from the drain to the source of the replica transistor and source the sense current when the sense current flows from the source to the drain of the replica transistor. The sense resistor can receive the output current such that the voltage across the sense resistor changes in relation to the current through the switch transistor.

The self-test circuit is configured to inject into the micro-electromechanical structure a plurality of injected test signals that are broad-band frequency-varying frequency signals, which are based on spread spectrum based modulation. The injected test signals may a magnitude that is below an observable threshold of the sensor signal as well as a test-signal bandwidth that overlaps with a substantial portion of the sensor bandwidth, including the stimulus of interest.

An exemplary system includes an edge-detection-based adaptive filter that identifies edge pixels and non-edge pixels in an image and selects a filtering technique for at least one non-edge pixel based on a comparison of the at least one non-edge pixel to a neighboring pixel region, wherein such comparison indicates whether the at least one non-edge pixel is a result of low-light noise.

Abstract: Integrated crash and vehicle movement sensing by use of distributed new multi-axis satellite sensors combines side and/or front/rear crash sensing with other applications requiring dynamic vehicle movement data like (but not limited to) roll and/or pitch detection as well as active suspension, head light beam leveling, etc. Depending on the required functionality, two or more satellite sensor modules are used, which measure multi-axis high-g and low-g acceleration, without needing any further sensor inputs like gyroscopes while achieving a high level of failsafe and redundancy.

Abstract: According to an example embodiment, a processor such as a digital signal processor (DSP), is provided with a register acting as a predicate counter. The predicate counter may include more than two useful values, and in addition to acting as a condition for executing an instruction, may also keep track of nesting levels within a loop or conditional branch. In some cases, the predicate counter may be configured to operate in single-instruction, multiple data (SIMD) mode, or SIMD-within-a-register (SWAR) mode.

Abstract: In one particular example, this disclosure provides an efficient mechanism to determine the degree of parallelization possible for a loop in the presence of possible memory aliases that cannot be resolved at compile-time. Hardware instructions are provided that test memory addresses at run-time and set a mode or register that enables a single instance of a loop to run the maximum number of SIMD (Single Instruction, Multiple Data) lanes to run in parallel that obey the semantics of the original scalar loop. Other hardware features that extend applicability or performance of such instructions are enumerated.

Abstract: Various methods and systems are provided to control a probe moving towards fluid held in a container. The probe is moved towards the fluid to take a sample of the fluid in the container. To take a sample, probe is actuated to hit the fluid surface and to pass the fluid surface by a predetermined distance. Capacitive sensing which incorporates the probe itself is used to support an approach engine for controlling the motion of the probe. The approach engine determines the speed of the probe based on capacitance measurements, and in some cases based on position information of the probe. The approach engine ensures the probe hits the surface of the fluid in the container in order to take a sample while ensuring the probe does not hit the bottom of the container.
