<p><a href="https://www.pmdtec.com/index.php" style="color:blue; text-decoration:underline" target="_blank"><span style="color:#e67e22">Pmdtechnologies</span></a><span style="color:#151b26"> in partnership with </span><a href="https://www.infineon.com/" target="_blank"><span style="color:#e67e22">Infineon</span></a><span style="color:#151b26"> announced the release of a fourth generation REAL3 image sensor. Named the RS2771C, the new single-chip 3D time-of-flight (ToF) sensor resides in a minuscule 4.6- x 5-mm package. Designed for the mobile devices market, the RS2771C can scan a face or hand for security purposes. It’s also able to scan a room and be used for augmented reality. </span></p>

<p><span style="color:#151b26">The RS2771C’s 150 k (448 × 336) pixel output comes close to HVGA standard resolution and is four times higher than that of most ToF solutions on the market today. </span></p>

<p><span style="color:#151b26">Patented SBI circuitry (suppression of background illumination) incorporated into every pixel makes the pixel array is highly sensitive to 940-nm infrared light. Samples of the chip are available and volume production is scheduled to start in Q4 2019.

<p>Two of <a href="http://www.ti.com" target="_blank"><span style="color:#e67e22">Texas Instruments'</span></a> latest RF-sampling transceivers, the AFE7444 and AFE7422, integrate four analog-to-digital converters (ADCs) and four digital-to-analog converters (DACs) into 17- × 17-mm flip-chip ball-grid-array (FCBGA) packages. This makes for a 75% smaller footprint than an equivalent discrete solution.</p>

<p>Capable of sampling up to 9 Gsamples/s per DAC and up to 3 Gsamples/s per ADC, the new chips can achieve up to 600% more data throughput than contemporary devices, according to TI. The AFE7444 is capable of receiving and transmitting up to 800 MHz from each its four antennae; the AFE7422 receives and transmits up to 1.2 GHz from each of its two antennae. The new chips are intended for use in multi-antenna wideband systems, 5G systems, software-defined radio, and direct RF sampling for radar.</p>

<p>A new sliding power connector developed by <a href="https://www.te.com/usa-en/home.html" style="color:blue; text-decoration:underline" target="_blank"><span style="color:#e67e22">TE Connectivity</span></a> &nbsp;promises to cut costs in novel ways. Intended for applications such as hard-disk drives, racks, servers, and storage units, the connectors are also suitable for high-current devices as well as large power supplies. Allowing equipment to be hot-swapped without shutdown, the new connectors minimize downtime, lowering maintenance costs. They also reduce the amount of cable management required within enclosures. This increases the space for air to circulate or for cooling solutions to operate. The new connector also promises a lower voltage drop and higher reliability over conventional types of cabling.&nbsp;</p>

<p><a href="https://www.portescap.com/" style="color:blue; text-decoration:underline" target="_blank"><span style="color:#e67e22">Portescap</span></a> recently expanded its line of Ultra EC dc brushless and slotless motors with the introduction of the 35ECS. Available in two lengths, the 35ECS60 and the 35ECS80, the 35ECS is a two-pole, 35-mm diameter motor capable of continuous speeds of 40,000 rpm.</p>

<p>The 60-mm-long 35ECS60 can sustain a peak torque of 1.1 Nm and the 80-mm-long 35ECS80 can output a peak torque of 2.0 Nm. The new motor is built with a laser welded front flange to withstand the forces present during high-torque reactions. Portescap incorporated its patented Ultra EC coil technology for reduced core losses and improved torque without additional friction or brush wear. Customized options are available, including Hall-effect sensors, onboard temperature sensors, gearboxes, encoders, six different coil variations, and modifications to the mechanical interface. The motor is well-suited for fans and pumps, portable and battery-powered applications, or wherever a design is up against severe weight or dimensional constraints.
