Abstract: An unlocking device includes a casing mounted to a side of a lock having a keyhole. A movable body is rotatably received in the casing about an axis. The movable body has a closed end having a through-hole. A key receiving seat is received in the movable body and has a passage. The keyhole is normally blocked by the closed end of the movable body. The movable body can be rotated to align the through-hole with the keyhole and the passage. A manually rotatable linking rod extends through the passage and has an engaging portion for coupling a key received in the passage. The key can be moved into the keyhole by moving the linking rod along the axis and can be rotated for a locking or unlocking operation.

Abstract: A pipe connection includes a main body, an inner sleeve, a water inlet connector, a water outlet connector, a circuit board, a control panel, at least one battery, a magnetically activated detector, an impeller, and a magnetic member. In operation, when the water flows through the impeller, the impeller is rotated, and the magnetic member is moved to pass by the detector intermittently so that the detector can transmit a detected signal to the circuit board which can calculate the rotation speed of the magnetic member so as to obtain the water flow rate. Thus, the pipe connection can calculate and indicate the water flow rate in the pipe so that when the flow rate of the output water from the pipe reaches a preset value, the user can shut the water flow to regulate and save the water flow.

Abstract: A high illumination LED bulb includes a transparent lamp holder and a transparent reflective envelope having an inner face coated with a reflective membrane having light transmittance characteristic. A chamber is defined between the transparent lamp holder and the transparent reflective envelope and receives an actuator, a radiator and a light emitting module electrically connected to the actuator. The light emitting module includes a substrate disposed on the radiator and at least one LED disposed on the substrate. Light radiated from the LED is transmitted to produce superior projection beam by the transparent reflective envelope and reflected to produce inferior projection beam by the reflective membrane. Reflected halo formed by projection of the superior projection beam and the inferior projection beam on the transparent lamp holder and the transparent reflective envelope can form side projected halo, thereby radiating light with a full emission angle.

Abstract: A weightlifting apparatus has multiple disc weights. Each disc weight has a round base and a round cover assembled on the round base. The round base has multiple locating slots formed therein. The round cover has multiple locating holes formed therethrough. When the locating slots align with the locating holes, lightweight weight plates or coins can be inserted into corresponding locating slots. When the locating slots misalign with the locating holes, the inserted weight plates or coins can be retained in the locating slots. Accordingly, easy weight adjustment and cost-saving effect can be achieved without requiring users to purchase an entire set of disc weights. With incremental fine weight adjustment of weight plates and coins, users can quickly adapt to the adjusted weight, and the exercise injury caused by large increment of weight adjustment can be avoided.
