Abstract: A pH measurement system includes a measurement apparatus that is capable of connection to a mobile device and a server and that includes a measuring instrument and a monitoring device. The measuring instrument includes a tube, and a sensor rod that is disposed is the tube and that is for sensing a pH value of a measurement target. The monitoring device includes a microcontroller communicatively connected to the sensor rod, an operation module for operation by a user, a communication module for communication with the mobile device and the server, and a display module for displaying information. The microcontroller provides the pH value to the mobile device or the server through the communication module.

Abstract: A memory card adapter device made of electricity insulating materials is exemplarily illustrated, and shape of the memory card adapter device is a pentagon. The memory card adapter device is used to switch a mini memory card or a micro memory card, and the memory card adapter includes a linking portion, a socket portion, and a transmission interface. The linking portion is a connection interface, having a plurality of metal conductive touch points used to be electrically connected to computer equipment. The socket portion is used to accommodate the mini the memory card or micro memory card. The transmission interface located inside the socket portion is used to electrically connect the mini memory card or the micro memory card, and the linking portion. A length of a distance between a longer side of the linking portion to an opposite side of which is 20 millimeters to 25 millimeters.

Abstract: A slide module structure of a drawer is composed of inner and outer slides. The inner slide includes two protrusions and a latch with a clamping arm on both ends. The outer slide includes a resuming base corresponding to the latch. The resuming base includes a slide slot for embedding a protrusion. A curved hook at the bottom of the driving member is hooked to the recession, and a guide clamping portion is at a front end for driving the latch, and a pressing portion is at a rear end. After the slide module is installed to the drawer, the latch of the inner slide and the resuming base and driving member of the outer slide are operated interactively to achieve an automatic push-back effect when the drawer is pushed back to its closed position, so as to prevent components of the drawer from being damaged.

Abstract: A drawer slide module structure is composed of an inner slide and an outer slide. The inner slide includes a latch body installed therein, and an indent and an end portion disposed at innermost positions on both sides of the inner slide. The outer slide includes a resuming base disposed at a position corresponding to the latch body of the inner slide, and a locking base installed at a rear side of the resuming base. With the design of a driving member in the resuming base swung with a link member as an axle point, the driving member and the link member will not be damaged, when the drawer is pushed back; if one of the drawers in the whole cabinet is pulled open, the locking base will latch the inner slides of other drawers, so that other drawers will not fall out freely.

Abstract: An improved structure slide track assembly comprised of an inner track, it having a check element on its exterior surface and a solid, stepped crown extending from the top of the check element and an outer track that contains a ball bearing channel rail and a center track. The ball bearing channel rail has a reticulated catch slot that is engaged by a spring-based pawl of the center track guide sleeve into a unitary structural entity. When the drawer is installed onto the outer tracks, while the check element stepped crowns at the drawer inner tracks force down press sections on the guide sleeves to disengage the ball bearing channel rails from the center tracks and enable easy sliding with the drawer. As such, the present invention achieves efficient installation and the protection of the ball bearing channel rails to prevent damage due to inappropriate installation.
