  • Patent number: 10790419
    Abstract: An LED filament comprises at least one LED section, a conductive section, two conductive electrodes and a light conversion layer. The conductive section is used to electrically connect two adjacent LED sections. The two conductive electrodes are electrically connected to each of the LED sections. Each of the LED sections includes at least two LED chips electrically connected to each other. The light conversion layer covers the LED sections, the conductive sections and the conductive electrodes, and a part of the two electrodes is exposed respectively. Since the LED filament includes the LED section and the conductive section, when the LED filament is bent, the stress is easily concentrated on the conductive section. Therefore, the breakage probability of the conductive wires connected within the LED section is reduced during bending. The quality of the LED filament and its application is improved.

  • Patent number: 10780560
    Abstract: An embodiment includes instructing a light source to emit light within a hardware socket configured to disengage a hardware component from a mounting surface. Emitted light received at a detector while a first portion of the hardware component is in contact with the mounting surface is detected. One or more instructions are sent to cause a relative rotation between the hardware component and the mounting surface. The embodiment further includes detecting that the first portion of the hardware component is no longer in contact with the mounting surface, and recording an extent of relative rotation that occurs in response to the one or more instructions to disengage the first portion of the hardware component from the mounting surface until the detection that the first portion of the hardware component is no longer in contact with the mounting surface. The extent of relative rotation is stored.

  • Patent number: 10717421
    Abstract: A braking force distribution method and system for multiple marshalling train compartments are provided. The method includes: determining a current train compartment of multiple target marshalling train compartments, calculating current axel loads of axels of the current train compartment, and distributing braking forces for the axels of the current train compartment in a positive correlation manner based on the current axel loads of the axels. The braking forces of the axels are distributed by using an axel load compensation technology. A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.
