● Manufacturing innovation

Ricoh developed the world’s first actuator incorporating a piezoelectric thin film, which is just several microns thick. This was the fruit of an inkjet printing technique that ejects raw materials to form the desired pattern. Conventional semiconductor processes form patterns by etching. The inkjet approach forms patterns directly by ejecting ink, greatly reducing costs. Prospective applications for this process include flexible displays, printed electronics, and photovoltaic cells.

● [Society] Employing technological innovations to bolster security and safety

Road surface inspection system

The aging of roads, bridges, and other infrastructure has become a major social issue. We can enhance security and safety by systematically maintaining and managing infrastructure.
Ricoh developed a road surface condition monitoring system. This vehicle-mounted camera system measures the deterioration of road surfaces. Because it can be mounted on ordinary automobiles, it can be used on residential roads on which it would be hard to measure changes with large specialist vehicles.
The system uses multiple stereo cameras* to assess the rate of cracks, the rutting depths, and the flatness in a single pass. It automatically decodes images through a model based on machine learning to reduce man-hours. Based on the above three data sets, the system calculates a Maintenance Control Index, which is a comprehensive benchmark for determining whether to undertake maintenance and repairs. The system also supports the creation of inspection records. It can also map results to visualize road surface conditions.

Environmental recognition technology for autonomous driving

We seek to enhance automotive safety by developing a range of stereo cameras, sensing, image analysis, and other technologies on vehicles. In collaboration with AZAPA Co., Ltd., we are undertaking demonstration tests in Semboku, Akita Prefecture, to use our technologies to verify autonomous driving systems and identify potential issues.
Our setup uses multiple stereo cameras and omnidirectional 3D recognition to eliminate blind spots and identify pedestrians, vehicles, and other objects, assisting with driving decisions in complex environments that are packed with obstacles. Based on image attributes, it is possible to calculate how far a vehicle has moved in real time and estimate its position. The technology also recognizes white lines and road shoulders and determines the legally drivable area. This assists with decision-making in complicated situations such as when stopping, overtaking, and entering intersections.

Vehicular all-directional sensors Vehicular all-directional sensors

Biomagnetic measurements

Our technology will contribute to advances in medical care. With a highly sensitive sensor, we can measure small amounts of magnetism from living bodies and precisely visualize nerve activity through noise removal and signal processing.
Our RICOH MEG magnetoencephalography system helps to diagnose developmental disorders in early stages, which has been very challenging to date. It can also diagnose epilepsy by evaluating a person’s neural state. Potential applications for the system include clinical treatment, the identification of complex brain functions, and applied research using neuroscience.
We are also working on neural activity measurements for the spinal cord, whose generated magnetic field is smaller, to confirm neurotransmission without burdening patients.
