摘要： A lens and a light emitting device applying the same are provided. The lens has a first profile along a first cross-section and a second profile along a second cross-section perpendicular to the first cross-section. The first profile is asymmetric with respect to the second cross-section, and the second profile is symmetric with respect to the first cross-section. A contour center of a light emergent surface of the lens is located on an intersection of the first cross-section and the second cross-section. The light emergent surface comprises a first curved surface and a second curved surface being connected with each other at the second cross-section. Furthermore, a curvature of the first curved surface and a curvature of the second curved surface are discontinuous at the contour center. The light emitting device applies the lens for receiving a light emitted from a light source and provides an asymmetric light output.

摘要： A portable probe stand assembly including a hand-held frame, a gravity tilt unit, and a probe holder. The hand-held frame includes a frame body with a cut-out and two gripping handles. The gravity tilt unit includes a movable part that has a pivot portion rotatably connected to the hand-held frame. The movable part tends to pivot due to gravity to turn the portable probe stand assembly to a hand-held state where a portion of an underside abutting surface of the movable part is disposed out of the cut-out. The portable probe stand assembly is convertible from the hand-held state to a usage state where the movable part is leveled via a pivot movement of the movable part upon engaging the underside abutting surface with a surface of an object.

摘要： A series of digit processing units (DPUs) are connected to form a finite impulse response (FIR) filter. Each DPU includes a register, a multiplexer, and a coefficient multiplier. The register stores and delays an input digital signal to be filtered. The multiplexer has inputs connected to the input node and to an output of the register, an output of the multiplexer for connecting to a next stage DPU. The coefficient multiplier is connected to the output of the register and multiplies the input signal by a coefficient or part of a coefficient. A group of DPUs can have multiplexers set so that the register of each DPU stores the same part of the input signal for processing a single filter coefficient. An adder is provided to sum output of the DPUs and output a filtered signal. The critical path of the FIR filter is independent of coefficient number and precision.
