Abstract: Techniques for a social networking system involve analyzing members' interactions to enhance follow recommendations. The techniques include calculating the number of follows generated by a first member and the number of follows received by a second and third member. The platform then computes a weighted follow utility score for two member pairs: the first comprising the first and second members, and the second comprising the first and third members. These scores are determined by equally weighing the follows generated and received, along with a probability of the first member following the second or third member. While the probability suggests a preference for the second member, the ranking system places the third member pair higher. Consequently, the first member is advised to follow the third member, based on this ranking. Finally, this recommendation is displayed to the first member on an electronic device, guiding their social interactions on the platform.

Abstract: A fuel injector includes a nozzle, and a nozzle check including a closing hydraulic surface. The fuel injector also includes a high pressure passage, a low pressure drain, a control passage, a check control chamber, and a valve seat. A relief passage is formed by at least one of an injector housing or a control valve in a control valve assembly. The control valve is movable among a rest position, a lifted injection position, and a lifted relief position where the high pressure passage connects to the relief passage. The control valve can be operated to selectively connect the high pressure passage to the relief passage to bleed fuel pressure to prevent over-pressurization. Related apparatus and methodology is also disclosed.

Abstract: Operating a fuel injector in a fuel system for an engine includes energizing a first solenoid actuator to move a spill valve from a first position to a second, closed position, and energizing a second solenoid actuator to move a fuel injection valve in the fuel injector from a closed position to an open position. A pull-in tier of a waveform energizing the second solenoid actuator is generated via a first current produced by a boosted voltage power supply and a second current produced by a lower voltage power supply. Arrival timing of the valve at the open position is detected based on a property of the second current, such that a valve arrival timing error may be used to trim the fuel injector. Related methodology and control logic is also disclosed.
