Methods for the optical transmission of polarization multiplex signals
InactiveUS7865080B2Reduce interactionStrong mutual interferencePolarisation multiplex systemsWavelength-division multiplex systemsPhysicsPolarization plane
In order to reduce mutual interferences between POLMUX and signals, the signals are transmitted with differed to each other carrying signals, thereby making it possible to obtain the circular polarization of each resulting POLMUX signal. Each second POLMUX signal is transmissible with an opposite circular polarization. In order to reduce also interferences when only one modulated data signal is transmitted through a POLMUX channel, a polarization plane of modulated data signals of each second POLMUX channel is turned at 45°. In a variant, polarization multiplex signals are produces and the resulting polarizations thereof in adjacent channels are perpendicular to each other.

Control circuit for current and voltage control in a switching power supply
ActiveUS20070115696A1Reduce load dependenceReduce noiseDc-dc conversionElectric variable regulationConductor CoilVoltage control
The present invention refers to a circuit for current and voltage control in a switching power supply controlled on the primary side, comprising a transformer with a primary-sided and a secondary-sided main winding, wherein energy pulses are transmitted from the primary side to the secondary side. Furthermore, a primary-sided switch switches on an off a primary current through the primary-sided main winding. A primary current comparator determines a switch-off time of the switch depending on the primary current. In order to reduce the load dependency of the output voltage, the control variable is variably amplified by a feedback network and additionally the control variable is reduced depending on the output load through a correction network. To reduce noise generated by the energy-rich pulse transmissions at low frequencies and the waviness of the output voltage, the control variable is fed back to the primary current comparator so that the duration during which the primary current flows through the primary-sided main winding is reduced differently. To reduce the susceptance to failure when determining the switch-on time, a comparator voltage depending on the control variable is generated as reference.

In one use, a motor mechanism for an electronic lock is disclosed. In one embodiment, the motor mechanism includes a split nut that travels along a threaded screw drive. When the split nut is physically limited from further travel along the screw drive, the split nut decouples and recouples with the screw drive to reduce drag on the motor and thereby reduce motor burnout. As a result, smaller, more cost effective and efficient electric motors may be utilized together with simplified electronics.
