Abstract: Embodiments of this application provide a positioning method and apparatus. The method includes: A first device receives, in a first system, a first trigger message for starting a positioning procedure. If the first device detects a first event, and the first device access a second system or moves to the second system, the first device sends a first message applicable to the second system. In addition, the first message includes location quality of service (QoS) applicable to the second system. According to this method, a device in the second system can recognize the first message and first location QoS, so that the device in the second system can continue a location service, to maintain continuity of the location service.

Abstract: A positioning manner includes user plane positioning and control plane positioning. A core network element receives a first message requesting for positioning a terminal device; and the core network element sends a first indication message to the terminal device based on a positioning capability of the terminal device, where the first indication message indicates to use a user plane positioning manner, and the positioning capability of the terminal device indicates a positioning manner supported by the terminal device.

Abstract: A configurable electrical connector. The connector has a housing body, a tower extending from the housing body and beyond a mating face, and a latch movably coupled to the housing body and/or tower. The tower is configurable according to a mating component. The tower can be a tower portion formed with the housing body. The tower can include an extender, with a lower portion disposed inside the tower portion and an upper portion disposed on the tower portion. The extender has an opening through which the latch can pass for engaging a mating component at the locked position. Such a configuration enables the connector to reliably hold a card taller than a standard card (e.g., according to DDR5 or below), and therefore enable the connector to be compatible with both standard cards and tall cards so as to support different storage capacities and data rates.

Abstract: The present disclosure relates to positioning methods and communication apparatuses. In an example method, a first location management network element performs first positioning processing on a measured device to obtain first location information. The first location management network element requests a first network element in which a positioning reference device exists to determine one or more first positioning reference devices. The first positioning reference device performs second positioning measurement to obtain second positioning measurement information. The first positioning reference device sends the second positioning measurement information to the first location management network element.

Abstract: The connector provides high performance transmission for high speed signals. The connector includes a subassembly having a subassembly housing holding conductive elements in a row and a shield disposed on the subassembly housing. The subassembly housing includes openings to ground conductive elements. The shield has ribs extending into the openings and contacting the ground conductors. The subassembly can have a second shield disposed closer to a mating face than the shield disposed on the subassembly housing. The second shield is configured to move with the mating ends of the conductive elements when a mating component is inserted into the connector. The connector has a housing with an opening positioned in a moving path of the second shield. Such a configuration meets signal integrity requirements in connectors design for 64 Gbps and beyond, while conforming to a standard that constrains connector physical dimensions.

Abstract: A connector for reliably transmitting high-speed signals. The connector includes a housing having a mating face, a mounting face opposite the mating face, and channels extending to the mounting face. Conductive elements are disposed in respective channels, and each has a mounting end extending out of the mounting face. A seal is disposed at the mounting face. The seal includes a first sealing element (e.g., plastic) and a second sealing element (e.g., sealant). The second sealing element is stacked on the first sealing element. Subportions of the conductive element adjacent their mounting ends are embedded in the second sealing element. Such a configuration enables complete sealing of openings at the mounting face of the housing so as to block contaminants from entering the connector from the mounting face and enable the conductive elements to transmit high-speed signals (e.g., at a speed specified by DDR5 standard) reliably over time.

Abstract: A pressure mount connector that conforms to standard physical requirements while providing high performance at high speeds. The connector includes a housing holding conductive elements. The housing has a mating face, a slot extending through the mating face, and a mounting portion. Each conductive element has a mating portion curving into the slot, a contact tail opposite the mating portion, and an intermediate portion joining the mating portion and the contact tail. The contact tail extends in an angle to the intermediate portion, which can change when a normal force is exerted onto a contact surface of the contact tail. Connecting the mounting portion of the housing to a mounting component can provide the normal force. The contact tail is thinner and narrower than the intermediate portion and can have extensions, which reduces the risk of permanently deforming the contact tail by the normal force and improves signal integrity performance.

Abstract: A connector for economic and reliable operation of systems, such as systems having tall cards. The connector has a housing body, a tower extending from an end of the housing body and beyond a position that a notch of a standard card would be in a height direction, and a latch configured to cooperate with tall cards. The tower can have a first portion extending from the end of the housing body and a second portion coupled to the first portion. The latch can have a first member pivotable about an end of a second member so as to move the second member up and down when the latch moves between a locked position and an unlocked position. Such a configuration enables the connector to provide reliable connections for tall cards, while compatible with physical requirements of industry standards, for example, in length/width directions.

Abstract: A connector for high density, high speed, and high performance electronic systems. The connector has multiple slots, each of which can receive a card. Terminals disposed on opposite sides of each slot connect the card inserted therein to a motherboard on which the connector is mounted. Each slot has a latch disposed at an end for retaining the card inserted therein when the latch is locked and releasing the card from the slot when the latch is unlocked. The connector has a reinforcing members configured to enhance the mechanical strength of the housing. Terminal tails are configured for solder ball attachments such that the terminals of adjacent slots are disposed closer. The tails are also configured such that a smaller solder area is needed on the motherboard. Such configurations improve signal integrity at higher speed and increases the tolerance of errors in the manufacturing process.

Abstract: An electro-hydraulic combination driven explosion-proof legged robot which includes a positive-pressure chamber body and a leg-foot assembly. The leg-foot assembly includes a hydraulic cylinder. A servo pump is arranged inside the chamber body. The hydraulic cylinder is located outside the chamber body. The chamber body has a chamber wall formed with oil inlet and outlet holes configured to intercommunicate the servo pump with the hydraulic cylinder. The leg-foot assembly includes a mounting bracket, a leg-foot forward-and-backward swing mechanism, a hip joint mechanism and a leg-foot mechanism. The leg-foot forward-and-backward swing mechanism and the hip joint mechanism are connected outside the chamber body through the mounting bracket. The hip joint mechanism is connected to the leg-foot mechanism and is able to drive the leg-foot mechanism to swing laterally inward and outward. The leg-foot forward-and-backward swing mechanism is connected to the hip joint mechanism in a coaxial transmission manner.

Abstract: A connector for high density, high speed, and high performance electronic systems. The connector has terminals held in a housing. Each terminal has a mating end, a mounting end, and an intermediate portion inbetween. A pair of cuts are disposed on opposite sides of the mounting end such that the mounting end is narrower than the intermediate portion. Each mounting end has a flat surface configured for a solder ball to be attached thereto and narrower than a diameter of the solder ball. This enables the solder ball to be reliably mounted to a contact pad on a circuit board that sized smaller than the solder ball. The contact pad can have a round shape such that a conductive trace can extend in any direction therefrom, which provides flexible routing. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

Abstract: A connector for use with high-speed signals. The connector has conductive elements aligned in a longitudinal direction. Each conductive element comprises a mating contact portion, a mounting tail opposite the mating contact portion, and an intermediate portion joining the mating contact portion and the mounting tail. The mounting tail comprises a connecting portion extending from the intermediate portion, a mounting end opposite the connecting portion, and a main portion joining the connecting portion and the mounting end. The mounting end has a diminishing longitudinal width in a mounting direction. The main portion has a longitudinal width narrower than the connecting portion. The connecting portions of adjacent conductive elements extend toward opposite direction such that the corresponding mounting tails are offset from each other. Such a configuration enables the mounting tails to be inserted into through-holes in the printed circuit board with high error tolerance.

Abstract: A nanozyme material and a preparation method thereof are provided. In the preparation method, Prussian blue (PB) is used to regulate the peroxidase activity of Fe,NA/CDs, and then gold nanoparticles are synthesized with Fe,NA/CDs as a reducing agent and a stabilizing agent. The nanozyme material has both a peroxidase activity and a Raman enhancement effect, which can be used for nanozyme-based surface-enhanced Raman spectroscopy (SERS). An embodiment of the present disclosure also provides a method for rapidly detection of a Pb2+ ion, which is based on a color change or an additional Raman SERS signal generation caused by nanozyme oxidation. Such sensing signals (colorimetric and SERS analysis) are derived from a catalytic oxidation reaction of ABTS or TMB, while the presence of Pb2+ specifically inhibits the oxidation, such that the rapid detection of Pb2+ can be achieved.

Abstract: A robust electrical connector is provided. The connector includes a housing body, conductive elements held by the housing body, and a slot extending in the housing body and configured to receive a mating component. The housing body has a mating face and a mounting face opposite the mating face. The conductive elements include mating portions curving into the slot and configured to mate with the mating component, and mounting portions extending out of the mounting face. The connector includes a tower extending from an end of the housing body, and a latch pivotably connected to the tower so as to secure the mating component in the slot at a locked position. The tower includes a base portion extending from an end of the housing body, and a cover portion disposed on the base portion. Such a configuration reduces the risk that the tower cracks during operation.

Abstract: A connector for use with high-speed signals. The connector has a housing, which includes conductive elements held in a row by a housing. Each conductive element includes a thinner portion and a thicker portion. The conductive elements are configured to make contact with a mating component at the thicker portions. The thinner portions are closer to mating ends of respective conductive elements than respective thicker portions. The housing is configured to provide voids selectively disposed underneath the conductive elements. Such a configuration increases impedances for the conductive elements at locations that would otherwise have lower impedance and therefore reduces impedance variations along signal transmission paths. Such a configuration can also reduce stub size and therefore reduce insertion loss. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

Abstract: An electrical connector comprises a housing and a plurality of contacts. The housing has a card slot for insertion of an electronic card and openings in two sides of the card slot. The plurality of contacts each comprises a plurality of separate members. Each member is in the shape of a beam with a contact portion, and each contact is inserted into one opening. A plurality of contact portions of each contact is arranged along an inserting direction of the electronic card. The electrical connector is easy to assemble, since it only needs to insert the plurality of members included in the contact corresponding to each opening in the housing into the opening. Thus, the cost can be reduced. The plurality of members are held on the housing through the corresponding opening and these members can be reliably fixed to the housing without an additional fixing component. Thus, the electrical connector has a simple structure.

Abstract: Reliable electrical connectors that enable simple architectures for systems in which connections are made through an opening of a casing. A connector may have a housing with an inner portion and an outer portion at least partially surrounding the inner portion. The inner portion may have first and second mating interfaces. The connector may have conductive elements each with first and second mating ends disposed in the first and second mating interfaces respectively. Intermediate portions of the conductive elements may be held by the inner portion of the housing to provide sealed electrical paths between the first mating interface and the second mating interface. The outer portion may be mounted against the casing with the first mating interface inside and second mating interface outside. The outer portion may have a support member embedded therein to improve its strength for an improved seal to the casing.

Abstract: A connector for use with high-speed signals. The connector includes conductive elements held in a row by an insulative member, a shielding member stacked on the insulative member, and a lossy member stacked on the shielding member and electrically connecting the shielding member to selected ones of the conductive elements. Each conductive element includes a mating end and a mounting end opposite the mating end. The insulative member includes first and second edges extending parallel to the row. The first edge and second edge are closer to the mating ends and mounting ends of the conductive elements, respectively. The shielding member includes a portion projecting from the first edge to provide shielding to the conductive elements beyond the first edge of the insulative member. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

Abstract: Connectors for use with high-speed signals. Mating connectors may include interlocking components that control the mated position of the connectors such that wipe distance can be reduced. These components may be compact such that they can be integrated into connectors with standardized exterior dimensions. They may be integrated into mating guides of the mating connectors. For one of the mating connectors, such a component may be a locking member disposed in and curving out of its guide such that the locking member mates with a matching feature of a component in the guide of the other connector. As the connectors are secured by these components, the conductive elements may be shorter than the lengths required by standards, which reduces the stub and therefore increases signal integrity. Such a configuration provides higher signal integrity at higher speeds, while conforming to standards that constrain mating and mounting interfaces.
