47results about How to "High synchronization" patented technology

A method and apparatus are provided to achieve frequency synchronization between a first clock at a first node and a second clock at a second node of a packet-carrying communications network. At the first node: a property of packet transmission through the network between the first node and the second node is measured; and the measurement of the property is sent to the second node. At the second node, the same property of packet transmission through the network between the first node and the second node is measured. The measurement of the property made at the first node and the measurement of the property made at the second node are used to synchronize the frequency of the second clock with respect to the first clock.

A high accuracy clock synchronization mechanism between a sender and a receiver in a communication network achieves time synchronization using broadcast beacons, directly at the PHY / MAC layer of the sender and the receiver, to minimize synchronization delay jitter. This provides a more efficient synchronization method than either NTP or SNTP, because multiple handshaking information exchange is avoided. Further, using beacons avoids the overhead of introducing additional synchronization packets in higher layer synchronization.

The invention provides a stainless steel air duct processing and welding equipment, which belongs to the technical field of air duct welding, and comprises a welding processing table, a rectangular welding track is arranged on the welding processing table, a telescopic mounting seat is fixedly arranged on the welding processing table, and the telescopic mounting seat is connected There is an anti-deformation part of the inner support, and the telescopic mounting seat is used to control the anti-deformation part of the inner support to perform telescopic movement to the rectangular welding track. The inner edge support unit has four inner edge support units and is distributed on the corresponding surface in a rectangular shape. The stainless steel air duct processing and welding equipment fits and supports the stainless steel air duct from the inside.

Loading system and method for loading substrates with electrical components. A loading system for loading substrates with electrical components comprises at least one transporting line (2), by means of which a first and a second substrate (16, 17) can be transported in a transporting direction, a basic carrier (3), a first carrier slide (4), which is mounted on the basic carrier (3) displaceably in a displacing direction, an elongated first carrier arm (8), the longitudinal axis (9-1) of which is oriented transversely in relation to the displacing direction and which is mounted on the first carrier slide (4) displaceably in the direction of its longitudinal axis (9-1), and a first loading head (10) and a second loading head (11), which are arranged at a fixed distance from each other on the first carrier arm (8) on opposite sides of the carrier slide in the direction of the longitudinal axis (9-1) of the first carrier arm (8).

The invention discloses a piece of color detection equipment, which comprises a workbench capable of bearing and testing work pieces, wherein the color detection equipment further comprises a feeding mechanism which extends to the workbench and is used for conveying the work pieces to the workbench, a detection mechanism which is arranged at the upper side of the workbench and used for detecting the color of the work pieces, a transfer mechanism which extends to the workbench and is used for transferring the work pieces, and a discharging mechanism which is used for receiving the work pieces transferred from the transfer mechanism. The color detection equipment compactly assembles the workbench, the feeding mechanism, the detection mechanism, the transfer mechanism and the discharging mechanism, and can be directly arranged in a sealed equipment shell for use, so that the land occupation is greatly saved; multi-step manual operations are saved; the processes of feeding, detecting and discharging are automatically and smoothly finished, so the efficiency is greatly improved.

A portable communications module (600) of FIG. 6 has an input (621) coupled to receive an incident signal. The input (621) split out a first audio channel containing a context audio track from the incident signal and directs the first audio channel along a first audio output path for selective audio output from a speaker (634, 620) either internally within or external to the module. The input (621)also directs a second audio channel in the incident signal to an RF audio transmitter chain for broadcast, the second audio channel comprising a composite audio signal from a plurality of audio tracks, each audio track embedded with a unique activation code that is present for substantially an entire duration of audio activity in each audio segment of each track. The input (621) is further arranged to apply a tone encoded signal in the incident signal to at least a tone decoder (640) in a data transmitter chain distinct from the audio transmitter chain (642). A microcontroller (650), responsive to recovered data, is arranged to translate the recovered data into a control signal related to functional control of remote equipment (102). And a data transmit chain (660) operates to modulate the control signal onto a carrier for broadcast to the remote equipment to effect its operational control. The tone encoded data is effectively filtered within the portable communications module to an extent that it is not amplified within the first audio output path and is not processed by the RF audio transmitter chain.
