Abstract: A continuous wave radar system comprises a substrate, a transmitter disposed on the substrate, a receiver disposed on the substrate, and an isolating device comprising a plurality of metal plates parallelly disposed on the substrate between the transmitter and the receiver for isolating leakage signal transmitted from the transmitter to the receiver. The metal plates are grounded with the transmitter and the receiver via electrical connection between the metal plates and the substrate. The metal plates are so arranged that an eddy current induced in each of the metal plates is directed away by grounding when the leakage signal passes through the metal plates.

Abstract: An operation mode control method implemented by a radar system, the operation mode control method includes steps of: (S1) receiving a single target tracking (STT) triggering data comprising a representation of triggering of a STT tracking mode and a selected tracking target to be tracked by the radar system; (S2) controlling a radar sensor to emit detection wave beam; (S3) controlling, the radar sensor to receive echo waves; (S4) analyzing, echo signal to generate STT target data; (S5) executing a STT program to obtain a tracking data of a selected tracking target; (S6) outputting the tracking data to a memory device for storage or to a human-machine interface (HMI) device for presenting to the user of the radar system.

Abstract: Methods and systems of an electronic circuit design system described herein provide a new abutment tool in which a chain post-processing function is called once per resultant chain of abutted instances after each chain is fully formed in a layout. In an embodiment, a process design kit (PDK) abutment update function is enhanced to support a new chain processing event that facilitates a creation of new top level figures in a cell view in which the chain lives, and further facilitate adjustment of parameters of instances of programmable cells in the chain.

Abstract: A system and method for optimizing a design layout by identifying features for abutment where shapes of the features that trigger the abutment are overlapping or within a predefined proximity of each other. The abutment process is implemented for features that have overlapping pins or that will have overlapping pins when abutted. Connectivity of abutted features is analyzed for the overlapped pins; pins of one of the abutted features are swapped so that at least one overlapping set of horizontal pins is connected to a same net; and a pin of the abutted features can be shortened as necessary to prevent short-circuit between pins connected to different nets. The overlapping pins are then merged. Pins can be shortened by cutting the pin or by adjusting pin style or pin size.

Abstract: A laser lighting device, including a laser light source and a light pipe, is disclosed. The laser light source can produce a laser beam with a diffusion angle not larger than 30 degrees. The light pipe is disposed in a light path of the laser beam, and has a light incident surface, a light exiting surface and several cut planes. The light incident surface is opposite to the laser light source, and the cut planes are located between the light incident and light exiting surfaces. Each of the cut planes is normal to the longitudinal direction of the light pipe, and has an area smaller than that of the light exiting surface but larger than that of the light incident surface. The areas of the cut planes increase sequentially along the longitudinal direction. The laser beam will be effectively collimated by the light pipe after passing through the light pipe.

Abstract: A device and method, which are utilized in an optical apparatus, for protecting eyes are disclosed. The optical apparatus includes a scanning-mirror component and a visible light source which is optically coupled to the scanning-mirror component. The optical apparatus emits a visible light beam to the scanning-mirror component by using the visible light source. The scanning-mirror component then reflects the visible light beam to emit the visible light beam to a scanning region. The device and the method for protecting eyes can determine at least one eye region in the scanning region, and then make the optical apparatus stop emitting the visible light beam at least within the eye region.

Abstract: An alignment structure, a laser lighting source module and an optical alignment method are provided. The laser lighting source module includes a substrate and a laser carrier. The substrate includes a first body and a first surface structure. The first surface structure is disposed on a surface of the first body. The laser carrier is used for carrying a laser emitter which includes a second body and a second surface structure. The second surface structure is disposed on a surface of the second body. At least a portion of the second surface structure is correspondingly engaged with at least a portion of the first surface structure so that the laser carrier may be aligned on the substrate.
