Analogue inductive preventative maintenance keeps Port open

Busy container seaports rely upon the ‘24/7’ operation of specialist container-handling vehicles called Straddle Carriers for loading, unloading and stacking containers. Often located at ports, being beside the sea can mean that they have to work in an aggressive and corrosive environment, requiring frequent maintenance. Because traditional, interval-based maintenance schedules …

Sensors ensure labels are aligned on boxes of bagged sweets

During high-volume production of confectionery, sealed cartons of bagged candy travel by conveyor to a labelling station. Contrinex’s RGB light-based photoelectric contrast sensor checks the label’s alignment and confirms the presence of print registration markings. If a label is blank, illegible or wrongly positioned, the carton is diverted to a …

Nanosensor can alert a smartphone when plants are stressed

MIT engineers have developed a way to closely track how plants respond to stresses such as injury, infection, and light damage, using sensors made of carbon nanotubes. These sensors can be embedded in plant leaves, where they report on hydrogen peroxide signaling waves. Plants use hydrogen peroxide to communicate within …
