摘要:
A system for treatment of gait disorders reflects, with electrical stimulation patterns fed to electrodes (1, 8) arranged at the patient, on the event of heel-strike and heel-off, the events being generated by a wireless heel switch (5). The pulse generator (4) also transfers the electrical energy needed to operate the heel switch (5) wirelessly. The event signal from the heel switch (5) is modulated in order to achieve a longer operating range.

A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced.
摘要:
An electrochemical cell has at least one plate element which can be cooled by a liquid coolant, such as water. The plate element has a surface that can be wetted for the purpose of cooling with the coolant. The surface of the plate element in the electrochemical cell is configured such that a contact angle between the surface and the liquid coolant is less than 90°. In the method for producing the electrochemical cell an additional method step is carried out which influences the wettable surfaces of plate elements for cooling with coolant and by which a contact angle between the surface and the coolant is decreased.
摘要:
A system for recording electroneurographic activity comprising at least three electrodes capable of sensing a nerve signal from a peripheral nerve and means for receiving and processing the sensed nerve signal to identify a signal indicative of a specific action being a movement of a body part performed by the patient and for producing a control signal in response thereto featuring means for rejection of signals originating from biological interference sources without adversely affecting the electroneurographic activity being measured.

A system for treatment of gait disorders includes an external device in the form of a pulse generator (4) with an integrated rechargeable battery and a device adapted to be implanted in the human body. The system features an external to the body placed antenna (3) for the inductive link between the external device and the implanted device. This antenna further incorporates an additional secondary coil (24), for inductively charging the battery in the pulse generator. The fixture on the antenna for mounting the antenna on the skin of the person is reused for being received in a charger fixture (20) on the charger, containing the primary coil (22) for the transfer of charging power.

A hydrophobic ABS plastics material is formed from an acrylonitrile-butadiene-styrene copolymer (ABS) plastic feed stock and a silicone additive. The hydrophobic ABS plastics material is used to produce a casing material, and also an electrical device. The hydrophobic ABS plastics material is ideally suited for protecting sensitive electronic components from moisture via a casing.

In a corotron device system, a moving element moves via a guide unit. A corotron having a corotron element and a corotron shield is provided. The corotron element is arranged relative to the moving element such that a distance from, and a parallel position of, the corotron element relative to the moving element substantially do not change.
