Abstract: Communication techniques (e.g., IP-based communications, multicast communications, unicast communications, wireless communications, etc.) are described. Devices may establish discrete communication sessions, with defined start and end times determined at the network layer of an Open Systems Interconnection (OSI) model, to exchange content.

Abstract: An electric guide rail type conveying system comprises a driving motor, a guide rail, a main transmission case, an auxiliary transmission case, a conveying member, and a moving trolley. Both ends of the conveying member are elastically deformably wound on the first rotating member and the second rotating member of a main transmission case body in two opposite winding direction. Before installation, the conveying member is basically wound on the first rotating member and the second rotating member. When a relative outer portion of the conveying member wound on the first rotating member is separated from the rotating member, a first elastic resilience opposite to one of the two opposite winding direction is generated; with the increase of a portion, separated from the first rotating member, of the conveying member, the first elastic resilience will increase; otherwise, the first elastic resilience will decrease.

Abstract: Provided is an electrical connector including an insulator, a plurality of terminals disposed in the insulator, a first housing surrounding the insulator and the terminals, a waterproof sealant, and a second housing disposed on the first housing. The first housing has a connecting port and a flange. The connecting port is configured to connect to another electrical connector, and the flange is disposed along the connecting port. The waterproof sealant is disposed onto the first housing along the connecting port and abutting the flange. The waterproof sealant is kept at a distance from the second housing.

Abstract: An electrical connector including an insulating body, multiple terminals, a first housing, and a sealing ring is provided. The terminals are disposed in the insulating body. The first housing is assembled to the insulating body and surrounds the insulating body and the terminals. An exterior wall of the first housing is divided into a first area and a second area which are different from each other. A coating layer is disposed onto a surface of the second area. A surface of the first area is a raw material surface of the first housing. The sealing ring is disposed in the first area.

Abstract: Disclosed is an electrical connector configured to be mated with another electrical connector along a mating axis. The electrical connector includes an insulating body, a plurality of terminals, a first shell, and a water-proof member. The insulating body includes a first part and a second part separated from each other along the mating axis to form a gap between the first part and the second part along the mating axis. The plurality of terminals are disposed through the insulating body. The first shell is sleeved on the insulating body. The first shell, the first part, and the second part form a closed space at the gap. The water-proof member is disposed at the insulating body and located in the closed space.

Abstract: The present disclosure provides a rotation type electric toothbrush. The electric toothbrush includes a brush handle module, a vibration module and a brush head module having a brush base, a brush cover and bristles. The brush cover and the brush base are in a detachable connection. The bristles are disposed on the brush base. The brush base includes a groove. The vibration module includes a motor and an eccentric shaft having a transmission connection with the motor. The eccentric shaft inserts into the groove. When the rotation type electric toothbrush is working, the eccentric shaft rotates eccentrically to contact a side surface of the groove, so as to drive the brush base and the brush cover to have a reciprocating rotation synchronously.

Abstract: An electrical connector including a plurality of terminals, a first insulating body, a second insulating body, a shell, and a waterproof member is provided. The terminals are respectively retained in the first insulating body and the second insulating body. The shell is sheathed to the first insulating body and the second insulating body. The shell has a front edge and a rear edge opposite to each other along an insertion direction. The front edge is used for mating another electrical connector. At least one opening is formed by the rear edge and the second insulating body. The first insulating body and the second insulating body are separated from each other. A space is formed by the first insulating body, the second insulating body, and the shell. The space is communicated with an external environment via the at least one opening. The waterproof member is filled into the space.

Abstract: An electrical connector, including an insulating body, multiple terminals, a metal shell, a collar, and a water-proof glue, is provided. The terminals are disposed in the insulating body. The metal shell is disposed outside the insulating body and surrounds the insulating body and the terminals. The collar is sleeved onto an outer wall of the metal shell. The collar has a first plate portion, a second plate portion, and a bending portion. The bending portion is connected between the first plate portion and the second plate portion. The first plate portion is connected to the outer wall of the metal shell, and the second plate portion is away from the outer wall of the metal shell. The water-proof glue is disposed between the second plate portion of the collar and the bending portion and the outer wall of the metal shell.

Abstract: An electrical connector including an insulating body, multiple terminals, a shell, and a sealing adhesive is provided. The terminals are disposed in the insulating body. The shell is assembled to the insulating body. The shell has an insulative exterior shell, surrounding the insulating body and the terminals. Portions of the insulating body and the terminals protruding from a front side of the insulative exterior shell are configured to be connected to another electrical connector. The sealing adhesive is filled between the shell and the insulating body and located at a rear side of the insulative exterior shell.

Abstract: Systems, apparatuses, and methods are described for detecting network service failure and potential source of failure in a communication network employing registration requests. A current quantity of registration requests may be compared against an expected quantity of registration requests, and a network alert may be sent based on the comparison.
