A method of time synchronization between a DS-TT module inside a logical TSN bridge of a communication network with a TSN Grandmaster (GM) in a TSN Time Domain of the communication network. The method comprises, at a NW-TT module inside the logical TSN bridge, determining a frequency rate ratio between a Time Domain clock frequency (f) and a TSN Time Domain clock frequency (f). Then, using the frequency rate ratio and respective times of receipt of a TSN GM synchronization message at an ingress port of the NW-TT module and at an ingress port of the DS-TT module to determine a DS-TT ingress residence time (R). Then, using the Rto synchronize the DS-TT module with the TSN GM.

Method of high precision time synchronization between a device-side time-sensitive networking (TSN) translator (DS-TT) and a TSN grandmaster (GM)

Described is a method of synchronizing a TSN NW-TT module inside a UPF with a Grandmaster (GM) in a Time Domain of the communication network. The method comprises receiving one or more PTP or gPTP messages on an N3 interface of the UPF. The method includes determining a first time offset value between the GM and the UPF N3 interface based on information received in the PTP or gPTP messages. A timing of the UPF N3 interface is adjusted using the determined first time offset value to synchronize the time between the UPF N3 interface and the GM. The method includes determining a second time offset value between the UPF N3 interface and the NW-TT module. A timing of the NW-TT module is adjusted using the determined second time offset value to synchronize the time between the NW-TT module and the GM.

A durable superomniphobic device is presented where the polymeric device has a surface that includes doubly re-entrant micropillars residing within pockets that are partitioned within a matrix of interconnected doubly re-entrant walls. The doubly re-entrant matrix can be in a pattern where walls that are equal to or greater in height to the micropillars intersect or otherwise contact to provide protection to the more fragile micropillars. These durable superomniphobic devices can be formed by injection molding and can repel liquids having a surface tension of about 18 to about 98 mN mand display liquid contact angle of greater than or equal to 150°.

This invention relates to an object with electroless plated coatings that includes an adhesion coating, a smoothening coating, a silver coating and an anti-scratch coating. A method of fabricating the electroless plated object is also described.

Fabrication of mirror-like coatings

The present invention develops a method of treating metallic or plastic substrates to form mirror finish. After several pre-treatment steps to modify the surface situation of the substrate, whether for metallic or plastic material, to enhance the adhesion of above coating layers, a layer of mirror finish will be applied, with the function of decoration shown with metal appearance and glossy. A changeable topcoat will be coated to protect below mirror finish layer and achieve colorful decoration. All materials and processing steps are environmentally friendly, and involved without expensive facilities.
