Newcastle upon Tyne, UK – July 3, 2017 – PrismTech™, a global leader in software platforms for distributed systems, today announced that its Vortex™ intelligent data sharing platform has been selected by Lely to ensure real-time data connectivity for the company’s automated robotic milking machines, the Lely Astronaut.

Dutch based agricultural technology company, Lely, supplies a complete portfolio of products and services ranging from automated feeding systems to barn cleaners and automatic milking robots.

The Lely Astronaut is an automated milking system that milks, feeds, and monitors the health of cows. The milking system also examines the quantity and quality of the milk received from the cows, and if necessary, it separates milk that is contaminated or is not to the correct standard. A transmitter on each cow enables the system to identify the cow via a unique number, and a management system maintains specific records for each cow. The Lely Astronaut uses these records to manage the milking and feeding of a cow when it enters the milking robot.

PrismTech’s Vortex enables real-time data connectivity for devices and machines based on the Object Management Group®’s (OMG®) Data-Distribution Service™ (DDS™) standard. Vortex includes DDS implementations that can be used to support a range of device technologies, operating systems and programming languages required by a project. It is a key enabler for systems that have to reliably and securely deliver high volumes of real-time data with stringent end-to-end qualities-of-service.

Vortex provides Lely with a wide set of capabilities for its control monitoring systems such as automatic discovery, shared memory architecture, configurable QoS framework, and platform portability which, together enable system-wide scalability and save valuable development time.

“Because of our constant drive to innovate we have been able to introduce a range of ground-breaking products to the market which really changed the lives of farmers,” said Nico Berkhoudt, Product Development Manager, Lely. “After an extensive evaluation, PrismTech was our clear partner of choice. Vortex will provide our systems with efficient, secure and interoperable real-time data sharing.”

“We are very pleased to add Lely to our growing list of customers who are using Vortex in their agricultural systems,” said Hans van’t Hag, Vortex Product Manager, PrismTech. “This is another example of the proliferation of Vortex into new and exciting Internet of Things markets.”

efabless Launches Open Source Hardware Development Framework for IC Designs

efabless corporation, an online design platform and marketplace for community-developed intellectual property (IP) and integrated circuits (ICs), today introduced Chiplicity, an open source framework for community members to create, share, make derivatives of and commercialize mixed-signal ICs.

“Chiplicity is a first of its kind and extends the efabless electronics community engineering concept from IP to ICs,” affirms Mohamed Kassem, efabless’ co-founder and chief technology officer. “We make chip design and productizing chips simple and broadly accessible. That’s why we call it Chip-licity.”

efabless developed Chiplicity as a development kit for integrated circuits, similar to hardware or software design kits known as HDKs or SDKs. Chiplicity includes all the tools needed for a full design cycle to design, verify, validate and prototype mixed-signal products, from idea to completed manufacturable GDSII files. It offers the efabless global community of IC designers a set of related library components –– an open source chip called Hydra, analog IP ready to wire, a standardized pad frame and a serial interface (SPI). A soft variant of the PicoRV32 RISC-V CPU core, developed by open source active contributor Clifford Wolf, is part of the efabless digital library located in the beta version of CloudV.

Community members clone marketplace components into their personal workspace on the efabless MyLib repository and create new designs. Final designs can be promoted to the marketplace for sharing with others and community members can manufacture their designs as prototypes through efabless on shuttles at X-FAB. To date, the Chiplicity platform has been used internally to tapeout two ICs.

Over time, community members will be able to create and verify increasingly complex mixed-signal ASICs. Chiplicity will offer a flexible pad frame generator and additional analog and digital IP, including a variety of microprocessor cores, additional open source IP and community-developed analog IP blocks. efabless also will offer open source test boards as library components to validate custom analog circuit designs.

Community members will be able to share designs under proprietary or open source licenses. efabless currently supports X-FAB’s XH035, 350 nm nanometer (nm) mixed-signal process. Its technology roadmap includes support for additional foundry processes, such as 180nm and 130nm nodes.

“Chiplicity is an essential piece of the overall ‘smart’ hardware, open innovation ecosystem,” remarks Mike Wishart, efabless’ co-founder and chief executive officer. “By combining community, open source and an innovative marketplace, we connect ideas with resources and apply a risk/reward sharing financial model that is unique to the IC industry. IC entrepreneurs can create new mixed-signal designs on limited budgets and ‘smart’ product inventors can find customized IC solutions to make their ideas commercially attractive.”

Plain and simple: Maximize your battery life

When you’re evaluating portable consumer electronics, you probably weigh a bunch of factors before opening your wallet. Lifestyle fit, product features, and battery life could be on your list. That’s why companies designing these products continually face the same power-management challenges—they need to safely extend runtime while optimizing battery performance.

The need for robust power management will continue to grow in the face of vast investment in artificial intelligence (AI), augmented reality (AR), and virtual reality (VR) technologies coupled with voracious consumer demand. Therefore, system design must revolve around efficiently utilizing the power available from ever smaller batteries to support more advanced features.

From a design point of view, system engineers must know the basics, such as when the battery is full and should be disconnected from the charger and when the battery voltage is discharged and should be connected to the charger. Optimizing charging and managing battery temperature tolerances to achieve better power management performance further complicates the system design challenge.

Most systems use a microcontroller (MCU) to monitor and control the battery supply and indicate low-battery or full-charge states. Dedicated battery-management solutions also provide a superb method for optimizing battery performance.

In all cases, battery monitoring and management circuits will control one or more of these key factors that affect the battery’s lifespan:

  1. How much current the battery can provide for a specified output voltage range over a particular time period
  2. How much current the battery can take in (during charging)
  3. The voltage level to which it can be charged (or maximum safety voltage)
  4. The voltage level to which it can be used (or minimum safety voltage)
  5. Temperature-range tolerance levels

Maximum safety operating voltage indicates that the battery is fully charged and ready for use. Minimum cut-off or disconnect voltage denotes when the cell has drained. Attempting to charge above the maximum safety operating voltage is possible, but comes with the risk of reduced lifespan and other potentially catastrophic consequences. The same risks apply when going below the discharge voltage level.

All of the above affects the battery’s inherent thermal stability and lifespan. Hence, voltage and temperature monitoring are critical.

A comparator with a window function is a cost-effective solution for monitoring battery voltage. This solution removes the need for additional software and reduces power consumption by allowing the system MCU to monitor battery voltage in sleep mode, while simply responding to flags from the comparator. Furthermore, the comparator circuit is small, ideal for applications with board space constraints.

The examples shown use the hysteresis of the comparator of desired voltage to monitor the battery voltage. VTRIP_HIGH would be the charged voltage and VTRIP_LOW would be the discharged voltage. When the output goes low, signaling an interrupt for the controller, it can be either a low- or high-charged voltage—the controller must ascertain which it is.

Maxim’s MAX40000, MAX40001, and MAX40002-MAX40005 series of comparators deliver low power in a small footprint with an internal reference that’s under 1 µA quiescent current. These specs make suit them for power monitoring with stringent power-dissipation requirements. The comparators’ lower quiescent current is comparable to the current typical self-discharge rate of the battery cells, making them useful for applications that involve long sleep times or low duty cycles coupled with a long battery life requirement.
