TTE Wrappers Protect System Operations

TTE Systems has launched a range of SafeTTYT Wrappers to maximise the reliability of embedded systems based on COTS processors and stand-alone operating systems such as Linux. When creating embedded systems used in safety-related or safety-critical systems, some form of protection mechanism is usually required to handle situations in which the main processor or operating system fails to operate as expected. Such failures can arise due to software errors (in code or in the operating system), the impact of electromagnetic interference or 'single-event upsets', or from various forms of hardware damage. If intending to use an off-the-shelf processor running Linux or another standard OS in the embedded system, it can be challenging to ensure that the system will operate safely at all times. In these circumstances, a SafeTTYT Wrapper from TTE Systems can help to guarantee that the system operates as required and can also simplify the certification process. A SafeTTYT Wrapper he

Allegro Develops Multi-Output LED RGB Driver IC

The A8512 from Allegro Microsystems is a multi-output white LED RGB driver IC for the LED backlighting of large-area LCD monitors and television screens. The device integrates a scalable-output boost controller operating in constant-frequency current mode control - adjustable between 300kHz and 1MHz - driving an external Mosfet. It integrates six internal current sinks, each capable of sinking up to 80mA, which can be combined together to achieve even higher currents. PWM dimming allows LED currents to be precisely controlled over a 500:1 ratio as a percentage of the maximum setpoint determined by the user. Multiple A8512 devices can be connected in parallel, with one master controller governing the boost stage and up to five slave controllers acting as LED sinks. This configuration allows up to 36 LED strings to be powered by a single boost converter, reducing the number of external components required. Other features include controlled start-up using enable, PWM signal or battery

Haas Control Overcomes Varying Machining Accuracy

Haas software engineers have designed into the Haas Control a facility called Maximum Rounding, which allows the user to define the machining accuracy of rounded corners within a selected tolerance. The default value is 0.05in (1.27mm) but it can be set to zero, in which case the machine will treat all corners as if an exact stop is required. Setting 85 is only a default value and the user can override this figure using a programmed command with the G187 code and specifying an E value. For example, G187 E0.5 would set the maximum corner-rounding value to 0.5mm for the duration of the program and will be cancelled when either 'reset' is pressed, M30 or M02 is executed, the end of program is reached, or E-stop is pressed. Most CAM-system post processors can be adjusted to automatically output a G187 for a roughing cycle and then alter the value again when the finishing cycle is run. The result is a shorter cycle time, more accurate and consistent parts and extended cutting-too

Oven Retrofit For Powder-Coating Subcontractor

Lanemark has completed the installation of a second oven retrofit heating system at powder-coating subcontractor B G Penny. The facility builds on a previous Lanemark installation at the Coventry site and is centred on burner replacement on an existing 'box oven'. 'The larger capacity second oven sits alongside the previous installation and, similarly, handles an overhead conveyor rail from which parts are suspended,' said Malcolm Penny, works manager at B G Penny. He explained that the latest oven is closely linked to a powder-coating process line and handles a variety of materials, ranging in thickness from 1mm to 15cm. This wide variation calls for precise temperature parameters to be specified and maintained depending upon the job in question. 'The heating requirement can range from 50 to 220C and, in some cases, calls for a temperature variation of only +/- 3C,' Penny continued. 'This target has been met every time to date, even with very temperature
