This paper presents a novel in-car design to recognise the driver's voice and to control in-car devices. In a non-stationary noise car environment, a speech recognition kit SR-07 with speech recognition chip HM2007 has less than 10% successful hit-rate. With an adaptive Wiener filter, the successful hit-rate has improved to as much as 75%.

CHIP-tuning for biological wastewater treatment plants
The demand for efficiency improvement in municipal and industrial wastewater treatment plants (WWTP’s) is increasingly based on problems related to the water quality, process stability and/or insufficient performance in the COD removal and/or nitrification process. New, stricter requirements or the need for higher removal efficiency intensify the demand for optimizing the existing technology by means of “tuning“. This article is about the efficiency improvement of existing biological treatment...
The Crunch Factor – Corn Chip Edition
Friday, January 29 was National Corn Chip Day.To celebrate, we tooka closer look at this wonder of the snack world and are sharingthe important role that moisture plays in the production of corn chips and snack foods in general. To get the scoop on corn chips, we spoke to Randy Rupprecht, QA Manager, and Mike Klein, Processing Manager, of Axium Foods. Every snack food has its own set of optimal conditions that will produce the perfect pretzel, crisp or chip. What is considered too much moisture for one might be...
Mesquite wood chips (Prosopis) as filter media in a biofilter system for municipal wastewater ...
The biofiltration system over organic bed (BFOB) uses organic filter material (OFM) to treat municipal wastewater (MWW). This study evaluated the performance of a BFOB system employing mesquite wood chips (Prosopis) as OFM. It also evaluated the effect of hydraulic loading rates (HLRs) in order to achieve the operational parameters required to remove organic matter, suspended material, and pathogens, thus meeting Mexican and US regulations for reuse in irrigation. Two biofilters (BFs) connected in series were...

We offer three different models(30 kg/h, 60 kg/h, 150 kg/h) for various potato chips sellers. Semi-automatic potato chips line can be applied in grocery, retail store, supper market, restaurant, etc. Semi-automatic potato chips processing line has the similar functions as fully-automatic potato chips production line, while manual potato chips line has much lower price and is specially...
Compressed and free of cooling lubricant - Case Study
RUF’s briquetting press increases the efficiency of Zollner’s aluminium production Zollner AG compresses more than 100 tons of aluminium chips per year using a RUF briquetting press. The mechatronics service provider thereby reduces the volume of this recyclable material to a fraction and isolates clinging oils and emulsions. By recovering cooling lubricant and thanks to increased prices for aluminium briquettes, the press has amortized itself within a very short time. Everyone has come into contact...
