An optical shape sensing system includes an attachment device () coupled at an anatomical position relative to a bone. An optical shape sensing fiber () is coupled to the attachment device and configured to identify a position and orientation of the attachment device. An optical shape sensing module () is configured to receive feedback from the optical shape sensing fiber and register the position and orientation of the attachment device relative to an anatomical map.

Shape sensing for orthopedic navigation

An electrical stimulation device and method of locating an electrical stimulation point of a human or animal. The device comprises a matrix of electrodes distributed on an electrode pad configured to be applied on a human or animal body and arranged for covering a plurality of the stimulation points of the human or animal. An electronic circuit is connected to the matrix of electrodes and configured for applying an electrical stimulation signal to the electrodes. A feedback signal, in response to an electrical stimulation signal, may be used in assessing the suitability of electrodes as an electrical stimulation point.

Electrical stimulation device for locating an electrical stimulation point and method

An electron tube provided with a semiconductor cathode for emitting electrons, which semiconductor cathode is arranged on a support, a source being arranged in the vicinity of the cathode, in particular, so as to face the free (Si) surface of the cathode, which source is capable of evolving, at the increased temperatures occurring during evacuation of the tube in the manufacturing process, a reducing agent such as F or HF, which passivates the free (Si) surface of the cathode.

Electron tube comprising a semiconductor cathode

In an electron tube based on a cold cathode, a cesium source (,) containing Cs,&mdash;Au,or Cs,&mdash;Sb,is provided near the cold cathode (,), preferably in contact with the first grid (,). Cesium is introduced into the source during activation of the tube. The vapor pressure of the cesium compounds is such that proper delivery of cesium is guaranteed throughout the life-time of the cathode.

Electron tube with a cesium source

A semiconductor cathode (,) in a semiconductor structure, in which the sturdiness of the cathode is increased by covering the emitting surface (,) with a layer of a semiconductor material (,) having a larger bandgap than the semiconductor material of the semiconductor cathode. Various measures for increasing the electron-mission efficiency are indicated.

Electron tube having a semiconductor cathode with lower and higher bandgap layers

Picture display device comprising an electron gun with cathodes having an enhanced dissipation of heat by virtue of an enlarged surface or an increase of the emissivity of the surface.

Electron gun with heat dissipation elements

Semiconductor device with a semiconductor cathode having an emissive part (pn junction) separated from a contact part which has locations at which a controlled breakdown occurs on a contact part metallization at excessive voltages, so that, during manufacture and operation, the emissive part in an election tube is protected from damage.

Semiconductor cathode and electron tube comprising a semiconductor

A semiconductor cathode (11) in a semiconductor structure, in which the sturdiness of the cathode is increased by covering the emitting surface (4) with a layer of a semiconductor material (7) having a larger bandgap than the semiconductor material of the semiconductor cathode. Various measures for increasing the electron-emission efficiency are indicated.
