TL;DR: In this article, the thermal properties of a compact, heterogeneously integrated gallium nitride on silicon carbide (GaN-on-SiC) and silicon assembly are investigated.
Abstract: The ever-increasing requirements for high device performance and compact size drive the communications industry to lookfor new materials, technologies, and integration concepts. This simulation-based study investigates the thermal properties of a compact, heterogeneously integrated gallium nitride on silicon carbide (GaN-on-SiC) and silicon (Si) assembly. Thermal simulations and parametric studies are used to determine how the heat spreading and temperature levels in the lateral and vertical directions are affected by the thickness of the SiC layer and the distribution of the thermal interconnects. Results show that a SiC layer thinned down to 100 µm shows more pronounced differences in its thermal characteristics compared to thicker ones, especially in terms of its backside heating. Aspects related to practical implementations are also considered.

TL;DR: In this article, an array antenna for ground surveillance radar is presented, which consists of five slotted waveguides, designed with an electromagnetic simulator program, and the results were combined to active VSWR and full, superposed radiation patterns for different scan angles and aperture distributions.
Abstract: This paper presents an array antenna for a ground surveillance radar The application requires a low-cost antenna with a wide-scan capability over an approximately 10% bandwidth at X-band It should also be designed for easy integration with the antenna active electronics The antenna aperture consists of five slotted waveguides, designed with an electromagnetic simulator program A prototype antenna was manufactured and the S-parameters and the radiation patterns of the individual waveguide columns were measured The results were combined to active VSWR and full, superposed radiation patterns for different scan angles and aperture distributions The measured data show very good performance for the full scan area ±40°

TL;DR: In this paper, the authors proposed a firing direction limitation device (FDL) for controlling the allowed launch angle range of a directable firing device (10) tiltable between at least two allowed maximum launch angles (MaxLAI, MaxLA2) defining a launch sector.
Abstract: Firing direction limitation device (15) for controlling the allowed launch angle range of a directable firing device (10) tiltable between at least two allowed maximum launch angles (MaxLAI, MaxLA2) defining a launch sector (4), wherein the firing direction limitation device (15) comprises a moveable limiting structure (16) configured to be arranged in connection to the directable firing device (10), where the limiting structure (16) is configured to be moveable between a first position (P1 ) and a second position (P2), wherein, when the limiting structure (16) is set in the first positon (P1 ), the directable firing device (10) is moveable within a first launch angle range (LARal ), and when the limiting structure (16) is set in the second positon (P2), the directable firing device (10) is moveable within a second launch angle range (LARa2), wherein the second launch angle range (LARa2) is limited in relation to the first launch angle range (LARal ), whereby the allowed launch angle of the directable firing device (10) is controllable.

TL;DR: In this paper, the authors proposed an improved method for positioning of an object by sweeping at least two line-shaped light beams having different inclination angles across an object comprising at least three nonaligned light-reflecting areas at known positions relative to each other.
Abstract: The present invention provides an improved method for positioning of an object. The method comprises the steps of: - sweeping at least two line-shaped light beams having different inclination angles across an object comprising at least three non-aligned light-reflecting areas at known positions relative to each other; - determining the bearings of said light beams when reflected by said light-reflecting areas; and - calculate the three dimensional position and/or tilt of said object relative to said light source based on said determined bearings and the known relative positions of the light-reflecting areas. By using two light beams having different inclination angles, two light-beam bearings are obtained for each light-reflecting area, which bearings can be used to calculate the three dimensional position and/or tilt of the object relative to the light source. According to an aspect of the invention, the proposed positioning method is used in a vehicle wheel alignment application wherein it allows for simultaneous wheel toe and camber-angle determination.
