Camfil to Acquire Handte
Air Pollution Control announces that its parent, Camfil, will acquire Handte Umwelttechnik GmbH in Germany and Handte’s operations in Switzerland, the
Czech Republic, and China. The acquisition, pending
approval from the authorities in Germany, is expected
to close in the first quarter this year. Handte will be
part of the Camfil APC business unit, which specializes in industrial dust and fume collection.
Handte is a manufacturer and provider of envi-
ronmental engineering products, filter technology
processes, and air pollution control applications.
“Handte has a full line of dust collectors, mist
collectors, and wet scrubbers that strategically
complement the Farr Gold Series cartridge dust
collection line. The integration of these product
lines will broaden our portfolio and strengthen the
company’s industrial air pollution control offerings
to customers in the U.S. and internationally,” says
Camfil APC president Lee Morgan. Key applications for these products include metalworking
and machining, automotive, foundry, mining, and
dry processing industries including chemical,
food, and pharmaceutical.
Camfil APC is a manufacturer of dust collec-
tion equipment and is part of Camfil, which deals
with air filters and clean air solutions. Camfil is
headquartered in Stockholm, Sweden.
Amputee Feels in Real-Time
with Bionic Hand
An artificial limb that enables amputees to grasp
at an object and feel it as though they were using
their real hand is now a reality, thanks to Freiburg
microsystems engineer Prof. Dr. Thomas Stieglitz
and the international research group participating
in the project LifeHand2. The scientists presented the findings of their project in the journal
Science Translational Medicine.
Surgeons implanted two ultra-thin electrodes
each directly into the ulnar and median nerves
in the upper arm of Dennis Aabo Sørensen, a
patient with an amputated lower arm. The electrodes send sensory data by means of electrical
impulses from the patient’s artificial hand directly
to his brain over the peripheral nervous system.
They give him information about the shape and
consistency of the objects he grasps at—even
when he cannot see them.
The patient learned to control his artificial hand
with only little prior training and more quickly than
the scientists had thought possible. He managed
to sense objects like a plastic cup, a mandarin
orange, and a heavy block of wood while being
blindfolded and to take hold of them with a precise grip and the right amount of force. The combination of technology and the patient’s biological
system worked almost intuitively.
The electrodes were developed in the labora-
tory of Thomas Stieglitz, professor of Biomedical
Microtechnology at the Department of Microsys-
tems Engineering of the University of Freiburg.
“Our research helps patients who have lost
a limb to move their prostheses in a completely
natural way. It is always a very special moment for
me as an engineer to see technological developments be implemented successfully on a patient
after many years in the lab,” says Stieglitz. As this
was only an initial test, the electrodes will have to
be removed after 30 days as per the European
directive on medical devices. The team plans to
conduct further studies on patients in Rome, Italy;
Lausanne, Switzerland; and Aalborg, Denmark.
Launched in 2008, LifeHand 2 project originated
from the European Union–funded project TIME and
the Italian project NEMESIS. The clinical director of
the study is Prof. Dr. Paolo Maria Rossini, and the op-
eration was performed by Prof. Dr. Eduardo Marcos
Fernandez. Both are from the Agostino Gemelli Uni-
versity Polyclinic in Rome. The project director is Prof.
Dr. Silvestro Micera from the Swiss Federal Institute
of Technology in Lausanne.
