Auto focus liquid lens magnifies up to x5 Varioptic, a Business Unit of Parrot SA, has added the Caspian u-316-7.5 auto focus lens modules to its portfolio, a unit specifically designed for microscopy applications. This compact objective includes the popular Arctic 316 Liquid Lens and offers a magnification from X2 to X5, with a typical focus range up to 1.7mm for a working distance of 5 to 7mm. It can refocus fast, with no mechanical movement and is suitable for the manufacture of auto focus microscopes for applications such as life science or industrial inspection. A Caspian Microscopy Development Kit is available, including X2, X3, X5 extension rings, power supply and an Auto Focus Microscope module. It can be ordered from Varioptic or its distributors. Varioptic www.varioptic.com Dual-band Wi-Fi antenna carries video streaming in small connected devices Antenova, manufacturer of antennas and RF antenna modules for M2M and connected devices, has added a small dual-band antenna for the Wi-Fi 802.11n and ac 2.4 – 2.5 GHz and 4.9 – 5.9 GHz bands. The antenna, called Mutica, is designed to fit within a reduced ground plane on the host PCB, for use in smaller Wi-Fi products and wireless accessories. The picture above shows the antennna evaluation board. Mutica is an SMD mounted antenna for all dual-band Wi-Fi applications, especially those requiring high speed data transfer and multiple-in multiple-out (MIMO) applications, for example security cameras, video cameras, set-top-boxes and devices for connected vehicles. Its specifications will also suit Wi-Fi access points, portable electronics, headsets, PC cards, games consoles, network devices and wearable electronics. 5Ghz 802.11ac offers High Definition video streaming with more channels and less interference than at 2.4GHz. This coupled with the high efficiency of the Mutica antenna will help to support faster data rates, fewer disconnects and better battery life in portable devices. Antenova’s approach to the design of its antennas, which it calls “Design For Integration” (DFI), makes use of the fact that the antennas are always embedded within a customer’s product; Antenova designs them so that the RF elements can easily be added to the customer’s design. Antenova www.antenova-m2m.com PIC32 Harmony software decoder framework Microchip has announced the PIC32 Harmony Software Decoder Framework and Microsoft Windows Media Audio (WMA) Decoder Library for 32-bit PIC32 microcontrollerbased consumer-audio application development within the MPLAB Harmony Integrated Software Framework. The WMA Decoder Library includes a new modular framework for audio decoders, including support for MP3 and AAC, allowing easier audio application development. Microchip says it will simplify development and increase flexibility of consumer audio products such as audio docks, automotive head units and home audio platforms. Microchip’s Audio Decoder Framework allows for audio software codecs to be added to a PIC32 design project. Rather than having to rewrite large sections of application code, the framework allows for easier integration into an existing application after the corresponding decoder library has been purchased. The WMA Decoder increases the depth of the library for PIC32 MCU-supported audio decoders, in addition to MP3 and AAC. This increases the range of audio formats that designers can choose to support. The audio decoder framework within the Harmony environment allows designers to add, subtract and switch among various software-based audio decoders. Microchip www.microchip.com IoT platform comes in a tiny single chip module Freescale Semiconductor claims to offer the smallest available single chip module (SCM) for the Internet of Things (IoT). As the IoT requires more processing horsepower to be packed into ever smaller spaces, the SCM line of products can integrate hundreds of components including processors, memory, power management and RF parts, which would otherwise be deployed on a six-inch board, into a tiny 17x14x1.7mm package — the size of a U.S. dime. At the Freescale Technology Forum (FTF) in Austin, Texas, Freescale unveiled the first product in its SCM portfolio. Designed to function as a computer on a chip, the i.MX 6Dual SCM is enabled for DDR memory and combines the performance of the company’s i.MX 6Dual applications processor together with a power management integrated circuit (PMIC), flash memory, embedded software/ firmware, and system-level security technology including random number generation, cryptographic cipher engines and tamper prevention. SCM products are engineered to dramatically reduce time-to-market, allowing an estimated 25 percent reduction in hardware development time — as well as greater than 50 percent reduction in size versus current discrete solutions. The module’s exceptional performance and connectivity allow customers targeting IoT markets to incorporate sophisticated predictive data analytics capabilities into their products, allowing for highly compelling and potentially disruptive end-products. SCM modules are ideal for applications such as 3D gaming goggles, where battery life and power are important; next-generation IoT drones requiring extreme processing performance for object recognition; and other IoT products, where highly advanced graphics and user interfaces are considered key to more mainstream adoption. Other markets well suited for SCM technology include wearables, next-generation medical equipment and autonomous sensing applications.
