摘要:
A displacement sensor employs an electromagnetic radiation source that generates a beam of electromagnetic radiation for measuring a feature of an object. The displacement sensor includes a displacement probe, a multi-dimensional diffraction grating and a plurality of photon detectors. A reflection surface, which is changed when the probe interacts with the object, interacts with the beam from the electromagnetic radiation source and reflects a beam from the reflection surface. The multi-dimensional diffraction grating interacts with the reflected beam and generates a pattern of diffracted beams. Each photon detector senses a different diffracted beam, thereby providing information about the state of the probe.

A probe includes a substrate and a tetragonal structure disposed on the substrate that has four end points. Three of the end points are disposed adjacent to the substrate. A fourth of the end points extends outwardly and substantially normal to the substrate. In a method of making a probe tip, a plurality of tetrapods are grown and at least one of the tetrapods is placed on a substrate at a selected location. The tetrapod is affixed to the substrate at the selected location.

A self-charging power pack (300) includes a cathode (312) and an anode (310) that is spaced apart from the cathode (312). An electrolyte (318) is disposed between the anode (310) and the cathode (312). A piezoelectric ion transport layer (322) is disposed between the anode (310) and the cathode (312). The piezoelectric ion transport layer (322) has a piezoelectric property that generates a piezoelectric field when a mechanical force is applied thereto. The piezoelectric field causes transportation of ions in the electrolyte (318) through the piezoelectric ion transport layer (322) towards the anode (310).

A method that provides for dynamic loop transfer for a method having a first set of instructions being executed by an interpreter is provided. An execution stack includes slots for storing a value of each local variable known to each subroutine while the subroutine is active. The method comprises suspending execution at a point for which a current execution state can be captured from the execution stack; assigning the value in each slot of the execution stack to a corresponding slot of an array of values; scanning the first set of instructions to identify a data type for local variable that is not known in the current execution state and shares a slot in the execution stack with a local variable that is known; and generating a second set of instructions for the method coded to be initially executed to declare each local variable that is known in the current execution state and each local variable for which a data type was identified, assign each declared variable with the value assigned to the slot in the array that corresponds to the slot of the execution stack in which the value of the variable is stored during execution of the first set of instructions, and branch to a target point in the second set of instructions that corresponds to the point at which execution was suspended.

In a method of making a monolithic elongated nanowire, a mask polymer layer is applied to a selected crystal surface of a seed crystal. A plurality of spaced apart elongated openings is defined through the mask polymer layer, thereby exposing a corresponding plurality of portions of the crystal surface. The openings are disposed so as to be aligned with and parallel to a selected crystal axis of the seed crystal. The portions of the crystal surface are subjected to a chemical nutrient environment that causes crystalline material to grow from the plurality of portions for at least a period of time so that monocrystalline members grow from the elongated openings and until the monocrystalline members laterally expand so that each monocrystalline member grows into and merges with an adjacent one of the monocrystalline members, thereby forming a monolithic elongated nanowire.
