  • Patent number: 10751458
    Abstract: A displacement sensing device is configured for a peritoneal dialysis system. The peritoneal dialysis system includes a housing and a syringe. The syringe is disposed on the housing and has a push rod. The displacement sensing device includes a guide rod, a probing module, and a resistance scale. The guide rod is coupled to the push rod, and the probing module is disposed in the housing and is fixed at the guide rod. The resistance scale is disposed at a side of the probing module. The probing module is configured to contact the resistance scale to obtain a resistance value of the resistance scale and determine a displacement magnitude of the push rod. In addition, a peritoneal dialysis system is also mentioned.

  • Patent number: 10660304
    Abstract: The invention is a pet feeding device provides a feeding mechanism on a basis of fixed time and fixed amount of food for a pet. The pet feeding device includes a base and a rotatable tray. The base has a first opening and a second opening communicated with each other, and the second opening connects the base and an exterior environment. The rotatable tray having third openings is assembled to the base and rotates about an axis. The feed pellets received in the pet feeding device fall into the third openings with a rotation of the rotatable tray. In a process of rotation, the first opening covers portion of the third openings correspondingly in a unit time, and the feed pellets in the corresponding third openings drop out of the pet feeding device via the first opening and the second opening.

  • Patent number: 10525864
    Abstract: A transportation device includes a motor, a transmission assembly, a position limiting assembly, two linkage assemblies, and two wheels. The transmission assembly is linked to the motor. The position limiting assembly includes two position limiting board portions disposed in parallel and adjacent to each other. The two linkage assemblies partially extend into a space between the two position limiting board portions and are pivoted to the two position limiting board portions, respectively. The two linkage assemblies are limited by the two position limiting board portions in a first axis. The two wheels are disposed in tandem along a second axis, respectively linked to the transmission assembly, and pivoted to the two linkage assemblies. The two wheels are driven by the motor respectively through the transmission assembly and are limited by the two linkage assemblies in the first axis. A transportation system including the transportation device is also provided.

  • Patent number: 10215599
    Abstract: A fluid sensing device is provided, including a main body and a light sensing unit. The main body includes a casing and a rotary member. A containing chamber is formed in the casing. The rotary member is rotatably disposed in the casing, and the rotary member has at least one transparent portion. A fluid flows into the containing chamber to drive the rotary member rotating around a central axis. The light sensing unit includes a first light transceiver module and a second light transceiver module disposed near the main body in an asymmetrical manner with respect to the central axis to transmit and receive the light passing through the translucent portion.
