The invention relates to a system for the protection of neuroprosthesis operation against unauthorized access to the function or operating data. The system is assigned to neuroprostheses for treating functional disorders of the nervous system. This neuroimplant protection system (NIS) comprises at least one neuroprosthesis component which is in contact or operational connection with nerve tissue. Neuroprosthesis operation takes place only during the period of a specific authorization and/or comprises an authorized data transmission between external component and implanted component and/or an authorized communication for monitoring and/or defining the neuroprosthesis functional state. The communication between external and implanted component is in encrypted form.

A system for monitoring the capacitor batteries of a three-phase filter circuit. Each capacitor battery is formed of a plurality of parallel legs each having a plurality of sectional capacitors which are connected in series with fuses. Adjacent ones of the sectional capacitors are coupled to one another. In a three-phase system, three capacitor batteries are coupled to one another in a Y-circuit configuration, the Y-circuit node being coupled to a reference potential, illustratively ground. The magnitude and phase of the fundamental frequency component of the current flowing from the Y-circuit node to the reference potential is monitored, variations therein being evaluated to identify defective sectional capacitors. Only variations in the Y-circuit node current which occur rapidly will trigger fault signals, thereby preventing false indications resulting from variations in temperature.

A tubular pushing member, when released by the trigger of a pistol grip moves forward under the pull of a spring, releases the catch of a sliding carriage which then quickly jabs forward under the pull of another spring to jab the needle of a syringe carried by it through the patient's skin, after which the further progress of the pushing member comes up against the plunger of the syringe, which it engages with an adjustable plunger mounted on a heel bracket of the tubular pushing member. The progress of the actuation of the syringe plunger may be slowed down, interrupted or allowed to accelerate at any stage of the injection by virtue of frictional engagement with the tubular pushing member by a rubber piece mounted on the top edge of the trigger plate and a spring weaker than the trigger spring makes it possible for the braking friction to taper off gradually for better control of the movement of the syringe piston as the trigger is pulled away from the tubular pushing member against the force of the trigger spring.
摘要:
A circuit for monitoring the voltage stress of a capacitor which produces an over-stress indicator signal responsive to the over-voltage history of the capacitor. If the measured voltage stress of the capacitor exceeds a predetermined over-voltage value, a characteristic-curve generator, having a predetermined transfer function, produces an output signal which is responsive to the measured voltage stress of the capacitor and the transfer function of the characteristic-curve generator. This signal is combined with a further signal which is responsive to a predetermined permissible continuous operation voltage value. The combined signals are conducted to an integrator having a predetermined integration time constant for producing an overload signal. The overload signal at the output of the integrator is a measure of the state of stress of the capacitor. Circuitry may be provided for disconnecting the capacitor from a transmission line in response to the output signal of the integrator. Also, plural capacitor voltage stress monitoring stages may be combined to monitor the capacitor voltage stress in a plurality of over-voltage ranges.
摘要:
A circuit for monitoring the capacitor battery of a filter circuit connected to a transmission line, the capacitor battery consisting of at least two parallel legs, each with a number of series-connected capacitors. A first signal is produced which corresponds to the total alternating current flowing through the capacitor battery. A second signal is produced which corresponds to the difference between the currents flowing through the respective parallel legs of the capacitor battery. The current difference signal is compared with a respective fraction of the total current signal. A fault indicator signal is produced if the difference between the difference current signal and the fractional total current signal exceeds a predetermined threshold value. Further circuitry is provided for correcting drift in the difference current signal, which may be caused by temperature variations or acceptable capacitor failures. Automatic ranging circuitry may be provided in embodiments of the invention in which the total capacitor battery current varies in amplitude over a large range.

The invention relates to aluminum pigments which are at least partially coated with lubricant, wherein the aluminum pigments have a relative breadth of thickness distribution Δh of from 30% to less than 70%, as determined by a scanning electron microscope thickness count and as calculated on the basis of the corresponding cumulative breakthrough curve of the relative frequencies of occurrence, according to the formula Δh=100×(h90−h10)/h50, and an X-ray diffractogram, measured on pigments in substantially plane-parallel orientation, having one or two main peaks which do not correspond to the [111] reflexes.The invention further relates to a method for the production of said aluminum pigments and to uses thereof and also to nail varnishes and printing inks containing said aluminum pigments of the invention.
摘要:
An OPW airbag having two opposing fabric layers made of warp and weft threads with at least one spacer that delimits the spacing of a chamber delimited by the fabric layers in the inflated state of the airbag. The spacer is formed by several of the warp and/or weft threads, so-called tethering threads, which, relative to the inflated state, extend from each layer in the direction of the opposing layer and are connected to warp and/or weft threads of the opposing layer. When warp tethering threads enter the opposing fabric layer, they each initially link with n weft threads and then float over at least n+1 weft threads in the interior of the chamber. When weft tethering threads enter the opposing fabric layer, they initially link with n warp threads and then float over at least n+1 warp threads in the interior of the chamber.
