Lattice and Intellivision develop intelligent HD video analytics for HDR-60 camera
Last month Lattice Semiconductor Corporation demonstrated a LatticeECP3 FPGA-based video camera supporting intelligent HD video analytics from IntelliVision at the ISC West Conference in Las Vegas. The low cost, low power LatticeECP3 FPGA on the HDR-60 Camera Development Kit integrates a complete suite of intelligent video analytics from IntelliVision combined with the IONOS ISP pipeline from Helion GmbH, enabling the design of low cost, small form factor smart cameras.
The LatticeECP3 FPGA can interface directly to a variety of HD sensors, process the image for intelligent analytics and output the video through its high-speed I/O or through a combination of its integrated SERDES channels, making the solution compelling for both security and, in particular, HDcctv camera applications.
The intelligence suite developed by IntelliVision allows OEMs access to a host of features that will allow for product differentiation and help developers and manufacturers create a “Smart Security Camera.” The suite includes intelligent video motion detection (iVMD), which can differentiate between an animal and a person, sending alerts only when necessary. Intelligent Intrusion Detection (IID) sends alerts when someone opens a door or enters a restricted space. With the Camera Tamper Detection (CTD) function, one can be alerted and act accordingly if a camera has been moved, blocked or knocked out of focus.
Bringing these video analytics features to the edge of the surveillance network can relieve server strain and allow for greater scalability, because fewer servers are required to keep the security network operating at its full potential. In addition, the functionality that has been added to the HDR-60 Camera Development Kit makes the surveillance infrastructure more efficient. Not only are costs saved on servers, but false alarms and human errors can be reduced, offering better security at a lower cost. Security is also improved due to proactive surveillance. For example, the camera can send an alarm so action can be taken immediately, rather than forensically reviewing the video only after the security breach has occurred.

HiWave announces stereo Bluetooth wireless speaker design
HiWave Technologies has announced a stereo Bluetooth wireless speaker reference design that provides 2 x13W burst power and runs for 30 hours (around 45 albums) from its small, 2200mAh Li-ion battery. Speakers based on the design enable users to stream audio from Bluetooth enabled phones, tablets and laptops. At typical listening levels the system, called Dyad BA3, consumes an average of less than 300mW, yet also accurately reproduces the audio peaks.
The system combines HiWave’s proprietary wide range loudspeaker technology, BMR, with HiAS2002 ultra efficient amplifier chip and CSR’s BC05-MM Bluetooth module. OEMs adopting the design would be able to deliver wireless, Hi-Fi
quality loudspeaker products to the market in less than 3 months.
The Dyad BA3 is the third design in HiWave’s series of reference platforms based on its BMR speaker drivers and ultra efficient wireless amplifier ICs. These speed time to market for HiWave’s customers, and its first reference platform, Dyad USB, was adopted and taken to market just months after its launch. Schematics and design notes for the DyadBA3
reference design are available under NDA via HiWave or one of its local sales channels.

Sony launches ultra-compact, digital colour HD block camera module
Sony Europe’s Image Sensing Solutions division has added an ultra-compact colour camera module to its range of FCB block cameras with digital outputs. While the FCB-SE600 has been designed for use in space-restricted environments, it measures 50x47.6x54.2mm, it features a motorised optical zoom, full HD (1080p at 30fps) picture quality and Sony’s Exmor 1/2.8 type CMOS sensor. The camera has been precision engineered in collaboration with the Sony Exmor development team to deliver impressive image quality, even in light levels down to just 0.1lx. It outputs in eight modes using the digital 4:2:2 Y/Cb/Cr scheme – including 1080p at 30 fps, 1080i at 60fps, 720p at 60fps and 720p at 25fps – to enable the optimisation of systems for speed, resolution and bandwidth.
The smaller design is suited to sports, video
conferencing, surveillance and public transportation applications, where size and sensitivity are vital. To further minimise the device’s size, the 83g Sony camera has a round edged design and incorporates a wide-angle 3x vari-focal lens (36x zoom including digital). The FCB-SE600 also includes the Auto ICR, Wide D, privacy zone masking, noise reduction

RFID reader for use outdoors or in harsh environments
New from Harting the Ha-VIS RF-R500 is a versatile and robust RFID reader that has been designed for applications outdoors or in harsh environments. The reader can capture information automatically on several hundred objects over distances of up to 16 metres and can immediately store data on an existing IT system such as SAP. Automatic capture minimises possible sources f error and enables the optimisation of logistics processes. The unit is protected by a robust aluminium housing with a protection category up to IP 64. A transmission power of 4 W, coupled with the inclusion of four antenna connections in each device, helps to deliver wide coverage at minimum cost.
A key application for the Ha-VIS RF-R500 is in maintenance management, where the monitoring and logistics processes can be greatly simplified and accelerated with considerable cost savings.
In the rail industry, for example, the reader is
suited to tracking wagons entering a maintenance shed. The unit's ruggedness allows it to be mounted next to the tracks, while the powerful processor and optimised software allow information on wagons to be captured while they are in motion.

Densitron OLED displays compatible with alphanumeric LCDs
Densitron’s Alphanumeric OLED modules have been designed to enable easy system integration and high display performance in an industrial environment. The displays are
suitable for a wide range of applications and for existing users of Alphanumeric LCDs who require a compatible upgrade. The modules are energy efficient and compact in size, with thickness between 1.3 and 1.6 mm. They have an extended operating temperature range of -40°C-80°C, up to 50,000 hours half life time and a near 170° wide viewing angle that meet industrial applications’ requirements. The displays come with standard interface options of 4/8 bit parallel, SPI and I2C and in- built font CGROM and Chip-On-Glass configuration.
Alphanumeric OLEDs are suitable for a wide range of applications, for example, card reader, DAB, measuring equipment, point of sale and
smart meter applications. The Alphanumeric OLED modules have a high contrast ratio of 10000:1 (most standard alphanumeric displays only have ~500:1) and the OLED displays are pin- to-pin compatible with many character displays on the market and hence there should be no hardware or software configuration issues in most cases.
USB Evaluation Kits are available and the alphanumeric OLEDs can be further enhanced through Densitron’s Engineering Design Service which offers options on integrating standard or custom display modules with touch screens, PCBs, Plastics, and/or Keypads.

Components in Electronics
touchscreens offer enhanced design flexibility and make integration into retail, hospitality, industrial and medical touch systems easier and more cost-effective. By eliminating the need for a front bezel, unique product designs are now possible, especially for human-machine interface (HMI) applications. In addition, without a front bezel, it is now possible to achieve reduced costs and complexities in supply chain and integration processes.
Further cost savings are also possible as lamination of a decorative front foil is no longer needed, and with a scratch-resistant 4H hardness rating that surpasses most other resistive touchscreens, the AccuTouch touchscreens provide durable, reliable use over long periods of
time. Standard Elo controller and chip solutions with Elo drivers are compatible with a wide variety of operating systems and work with the new AccuTouch touchscreens to facilitate worry- free touch performance. Available in 7-, 12, 15 and 22-inch sizes, the
new Elo TouchSystems AccuTouch zero-bezel 5- wire resistive touchscreens deliver accurate touch responses in high-use applications, seamless integration and customisation capabilities, and design aesthetics without the need for a front- bezel that can trap dust and dirt as with traditional resistive touchscreen displays. Units will begin shipping worldwide in April 2012.
