Abstract:
A cochlear implant device includes a deformable and stretchable flexible strip composed of a biological compatible material and positioned about a longitudinal axis so as to form a spiral. The implant device has a plurality of conductive strips with electrode windows formed so as to expose a segment of each conductive strip. A density of the electrode windows is sufficient to monitor a distance of the flexible strip from a non-conductive tissue of a patient in a 360 degree field of view about the longitudinal axis. A method of inserting a cochlear implant includes providing a multi-joint robot comprised of a series of actuator units, guiding the multi-joint robot into an inner ear of a patient, monitoring the position of the multi-joint robot relative to a non-conductive portion of the patient; and applying current to the multi-joint robot so as to adjust the position of the actuator units.

A printed circuit for forming deflection coils used, for example, in a scanning electron microscope. The printed circuit permits some of scroll coil circuits to be connected with an external circuit with or without connecting them in series. There is also disclosed a printed circuit capable of forming deflection coils which are small in size but produce strong magnetic fields. A printed circuit according to the invention comprises a sheet on which the scroll coils and indicia are printed. When the sheet is wound into a cylinder, the scroll coils are arranged circumferentially.
Abstract:
A preferably low dielectric constant polymeric bonding layer is applied or bonded (i.e., laminated or coated) to at least one side of a preferably low dielectric constant polymeric delay line substrate. Preferably, the melting or softening point of the bonding film is lower than the melting or softening point of the substrate so that the application (e.g. lamination) step is carried out at a temperature which is above the softening point of the bonding film, but below the softening point of the substrate (thereby insuring the integrity of the delay line circuit). Thereafter, the delay line/bonding layer assembly is rolled up and head sealed so as to melt the bonding layer, thus heat sealing the delay line package. As the package heats up (in, for example, a tightly fitting die), the materials expand and provide sufficient pressure to bond the circuit together.
Abstract:
A time delay device for adjusting the arrival time of an electronic signal at a specific area in a circuit pattern is presented. The time delay device is comprised of a coplanar flexible circuit having a conductive pattern consisting of a signal line in a ground shield. The signal line is serpentine and makes one or more passes back and forth on the dielectric surface of the flexible circuit. The ground plane covers substantially the entire surface of the laminate except for a small gap on either side of the signal line. This circuit laminate is then tightly rolled up and permanently packaged in a suitable sheath or by encapsulation.
