Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

Abstract: An optical photographing lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The second lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The third lens element has two surfaces being both aspheric. The fourth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof, wherein two surfaces thereof are aspheric. The fifth lens element has an image-side surface being convex in a paraxial region thereof, wherein two surfaces thereof are aspheric.

Abstract: An electronic system using a USB type-C port and an abnormal elimination method thereof are provided. After sending a hard reset request to a power adapter, a host device determines whether to enter an error recovery state according to whether an initialization signal is at a first preset level for a first preset time, so that the initialization signal is changed to a second preset level, or whether to force the initialization signal to change to the second preset level according to whether the initialization signal is at the first preset level for a second preset time.

Abstract: An assembling structure for a vehicle carrying device is provided, including: a tubular member, a first abutting member, an expansion mechanism and an actuating member. The tubular member has an axial direction and is configured to be inserted within a trailer hitch. A wall of the tubular member has a through hole. The first abutting member is movable along the axial direction and disposed in the tubular member. The expansion mechanism includes a second abutting member disposed on the first abutting member and an elastic member. The second abutting member is located within the through hole and urgeable to move by the first abutting member. The elastic member is disposed between the second abutting member and one of the tubular member and the first abutting member so that the second abutting member has a tendency to move radially in a direction toward the first abutting member.

Abstract: A foldable positioning structure and a bicycle carrier including the same is provided. The foldable positioning structure is for being mounted on a main body of a bicycle carrier, the main body includes a first rod member and a second rod member which are rotatably connected with each other, the foldable positioning structure includes an abutting assembly, a controlling assembly and a linkage. The abutting assembly is disposed on the second rod member and movable relative to the second rod member. The controlling assembly is rotatably disposed on the second rod member and slidable relative to the second rod member, and the controlling assembly has an engaging portion which is radially disposed thereon. The linkage is connected to and between the abutting assembly and the controlling assembly.

Abstract: A bicycle carrier is provided, including a main rod, two lateral rods, a middle rod and a base. The two lateral rods are disposed on two sides of the main rod. The base is disposed on the main rod. The middle rod is swingable and foldable relative to the base when the middle rod is pressed downwardly relative to the base.

Abstract: A positioning clamp of the present invention includes a tightening body and a fastening assembly. The tightening body includes an insertion hole. Two ends of the tightening body are spacedly arranged. The fastening assembly is disposed on the tightening body and is movable between a fastening position and a release position.

Abstract: A pivoting mechanism includes a rotation assembly and a fixation assembly. The rotation assembly includes a first member and a second member which are rotatable with respect to each other. The fixation assembly includes a first fixation member, a first elastic member, and a first pushing member. The first fixation member is received in the rotation assembly. The first fixation member selectively blocks the first member and the second member. The first fixation member is disposed between the first elastic member and the first pushing member.
