    Abstract: This is generally directed to adjusting signaling properties based on cable attributes. In some embodiments, the cable attributes can include information such as the length of a cable, the diameter of a cable, the type of plug on a cable, the type of or presence of shielding on a cable, or any combination of the above. This information can then be used to determine the appropriate signaling properties for that cable (e.g., with respect to an EMC standard). The appropriate signaling properties may, for example, optimize the signal that is used to drive the cable while still allowing the cable to generate emissions that are within acceptable EMC standards. In some embodiments, the appropriate signaling properties can include factors such as the drive strength of the signal, the slew rate of the signal, the maximum voltage of the signal, the frequency of the signal, or any combination of the above.

    Abstract: A power converter circuit may convert alternating current signals into direct current signals. A load may be powered from output terminals that are provided with the direct current signals. The power converter circuit may have a transformer with primary and secondary sides. A transistor on the primary side may be controlled using a pulse width modulation controller. A diode may be coupled in series with the secondary side of the transformer and the load. To improve efficiency at larger load currents, a synchronous rectifier control circuit may modulate a transistor on the secondary side that is coupled in parallel with the diode. The synchronous rectifier control circuit may monitor voltage pulses on the transistor on the secondary side or may make direct load current measurements to ascertain how much load current is flowing. Under low or no load conditions, synchronous rectification can be inhibited to improve efficiency.

    Abstract: A transmitter device in an inductive energy transfer system includes a first transmitter coil operatively connected to a first resonant circuitry. A receiver device includes a first receiver coil operatively connected to a first resonant circuitry. The first transmitter coil and the first receiver coil form a first transformer. The transmitter device, the receiver device, or both the transmitter and receiver devices can also include an auxiliary coil or inductor, which may form an auxiliary transformer. Energy can be transferred from the transmitter device to the receiver device using the first transformer or the auxiliary transformer. The transfer of energy may be adaptively adjusted based on the efficiency of the energy transfer. For example, the transfer of energy can be adjusted based on the operating conditions of the load.

    Abstract: Techniques for mounting contacts of a connector are provided. One technique involves actively and continuously monitoring contacts being used and the contacts not being used in a connector in order to determine potential dendrite growth and/or potential corrosion due to liquid intrusion or the like. Another technique includes lowering a bias voltage on a power contact and performing a system detect prior to enabling operational voltage/current on the contact.

    Abstract: A first electronic device optically communicates with a second electronic device. Each of the devices includes one or more optical transmitters, one or more optical receivers, and one or more lenses where each of the lenses includes at least a first and a second optical path that are optically isolated from each other. When the first electronic device transmits data to the second electronic device, an optical transmitter of the first electronic device transmits to an optical receiver of the second electronic device via the first optical paths of the lenses of the first and second electronic devices. Similarly, when the first electronic device receives data from the second electronic device, an optical receiver of the first electronic device receives from an optical transmitter of the second electronic device via the second optical paths of the lenses of the first and second electronic devices.
