The ProBeam BF50RG has a zoom range of 1.6x, allowing for placement at throw ratios of 1.30 ‐ 2.08. Throw distance can be quickly calculated using the screen width: Throw Ratio = Throw Distance/Image Width. Learn more: https://bit.ly/3XKsRNo #ProjectorReviews #Projector #LG #ProBeam #BF50RG

Our work on a planar true-time-delay 2D scanning multibeam network was just featured on this month's issue of IEEE Transactions on Antennas and Propagation ( https://lnkd.in/eMSQk3ni ). In this work: 1) We derived a formulation for designing M-beam (HxV)-antenna true-time-delay planar multibeam networks capable of scanning in arbitrary directions in the 2D plane 2) We designed and measured an 8-beam (2x4)-antenna network capable of exciting 8 squint free beams that can scan the azimuth and elevation planes across the entire 24-40 GHz range of instantaneous bandwidth.

#ThrowbackThursday - The SLS 2.0 upgrade project progresses steadily towards completion in 2025. Let's take a look back at the development of the Swiss Light Source SLS since its shutdown and how SLS 2.0 is coming along: 🔦 30 September 2023: The SLS was shut down and the 'dark time' began. 🏗️Autumn 2023: The concrete roof of the electron ring tunnel was opened, and 4,000 tonnes of concrete moved away. 🔧 Winter 2023/24: The old equipment was removed, leaving the electron ring empty. 🛠️ Spring 2024: Installation of girders began. ⚡ 21 March 2024: The first arc was successfully installed. 🌀 Summer 2024: By end of July, 7 out of the 12 new arcs have been installed, and work has begun on the new insertion devices, cavities, and front ends of the experimental stations. #UpgradingSLS #SLS2.0 #LightSourceScience #WorldChangingScience #SynchrotronScience

Pocket or tunneling techniques are commonly used in colonic ESD given limited submucosal space. Traction is an alternative technique which requires circumferential incision first ( the traditional way). Occasionally, gravity can provide the traction needed to perform colonic ESD without resorting to pocket or tunneling method. In this video, I am illustrating a case in which gravity assisted in colonic ESD by providing adequate traction to expose dissection planes. In addition, I am highlighting an efficient closure method using tacking system ( an approximation device) with clips to achieve complete closure.

A fiberglass antenna is a type of antenna encased in a protective fiberglass shell, which provides durability and resistance to environmental factors such as wind, rain, and UV radiation. These antennas are commonly used in various applications

EVERSPIN AEROSPACE MRAM can protect data against high-level radiation, making it well-suited for space applications. Along with high-temperature operation, MRAM offers high reliability for rugged system design. The ability to reprogram MRAM while in space allows a system to be reconfigured without any limit to endurance, and no need for wear leveling. Explore the proven performance of Everspin's MRAM solutions through a technical case study by our partner, Cobham Advanced Electronic Solutions (CAES, now Frontgrade). A worldwide leader in the space memory market, Cobham Advanced Electronic Solutions ships production-grade MRAM based on Everspin’s world-class technology to provide the space industry with radiation-hardened, highly reliable non-volatile memory that is immune to Single Event Upsets (SEU), low voltage Single Event Latchup (SEL), and Single Event Gate Rupture (SEGR).

So there is no one-fits-all solution.   ❓ 𝐇𝐚𝐯𝐞 𝐲𝐨𝐮 𝐜𝐨𝐧𝐬𝐢𝐝𝐞𝐫𝐞𝐝 𝐭𝐡𝐞 𝐢𝐦𝐩𝐚𝐜𝐭 𝐨𝐟 𝐫𝐚𝐝𝐢𝐮𝐬 𝐨𝐧 𝐲𝐨𝐮𝐫 𝐥𝐚𝐭𝐞𝐬𝐭 𝐦𝐦𝐖𝐚𝐯𝐞 𝐝𝐞𝐬𝐢𝐠𝐧? Which return loss do you aim for?

While recently showcasing our indoor positioning solution VENUE at MODEX, a common question was if there were any limitations or challenges in using geomagnetic positioning.     Our answer:     When using geomagnetic positioning there are certain limitations and challenges to consider:    Magnetic field variations: Magnetic fields are influenced by factors other than the building structure, such as nearby large metallic objects or electrical currents. These variations can introduce errors in positioning.    Calibration and mapping: Creating accurate reference maps of the magnetic fields requires careful calibration and mapping processes.  The TPI team has optimized this process to account for variations and changes over time.    Limited to indoor environments: Geomagnetic positioning is used for indoor positioning as it relies on the unique magnetic fields generated inside of buildings.     Contact us at tpi.info@tdk.com with any additional questions about VENUE.   #TDK #TDKTrustedPositioning #TrustedPositioning #sensors #PositioningSoftware #INS #GNSS #InertialNavigation #LocationSystems #RTLS #TDKGlobal #VENUE #MODEX2024 #SupplyChain #Logistics

But can it really be accurate at that angle? A client was surprised we could capture this point under a parked vehicle...I guess most people still expect survey poles to be vertical! I did a few tests with our R12i antenna to quantify the difference from a vertical to a severely inclined measurement - 2 cm horizontal and 4 mm height difference is acceptable for many applications. It isn't a brand new feature, but it takes #productivity to the next level - so #kudos to #Trimble for this IMU implementation. #geospatial #surveying #vermessung #gnss #r12i
