Abstract: An office chair includes a frame having a tube with a tapered inner periphery and a plurality of legs extend from the tube. A C-shaped sleeve is movably received in the tube and has a tapered outer periphery. The sleeve has a threaded inner periphery so as to be threadedly engaged with a seat post. Two notches are defined in the tapered outer periphery of the sleeve so that two pins extend through the tube and are engaged with the two notches to restrict the sleeve from being rotated. The sleeve is firmly clamp the seat post when a load is applied downward the seat post. When lifting the seat post, the sleeve is raised and loosened so that the seat post is adjustable.

Abstract: A heat dissipating device has a conductor holder and a heat conductor. The conductor holder is securely attached to the CPU base and has a through hole. The heat conductor is securely connected to the through hole in the conductor holder and contacts with the CPU. The heat conductor comprises multiple heat conductive elements made of a material with good heat conductivity. One end of the heat conductive elements are twisted together to form a bound section on the first end of the heat conductor. The other end of each heat conductive element is far away from the other element so as to form an expansion section on a second end of the heat conductor. In such an arrangement, the heat generated by the CPU can be efficiently dissipated from the expansion section of the heat conductor.

Abstract: A grip tape is formed of a tape body and an elastomer. The tape body has an inner surface and an outer surface. The elastomer is fastened to the inner surface of the tape body such that the elastomer is extended along the longitudinal direction of the tape body. The tape body is wound spirally on a handle to form a grip segment on the handle in such a manner that the elastomer is located in the grip segment, and that the length of the elastomer ranges between 30% and 70% of the total length of the grip segment.

Abstract: Footwear, particularly an athletic or sport shoe, having a sole with a visible, replaceable cushioning cassette, and method for modifying impact response capacity or color pattern by removing and replacing the cushioning cassette. The invention also provides footwear, comprising a sole; and an upper connected to the sole, the sole comprising an outsole; and a midsole, the midsole comprising a midsole section wherein walls of a periphery of cells form in the midsole section at least one cavity for receiving a cushioning cassette, which, when within the cavity, is visible through clear material of the sole when viewed from outside of the footwear.

Abstract: There is disclosed an apparatus and a method for forecasting output voltage of a battery of a digital camera. A dummy load is disconnected after the digital camera is powered on. An output voltage of the battery is obtained when he dummy load is off. The dummy load is then conducted. An output voltage of the battery is obtained when the dummy load is on. An internal resistance of the battery and the output voltage of the battery in operating the power consumptive elements are determined based on the output voltages, so as to obtain the voltage drop of the output voltage of the battery caused by power consumptive elements thereby being aware of the remaining power of the battery and obtaining the maximum power supplying efficiency for the digital camera.

Abstract: A column positioning device for a drill press includes a base having a post and a positioning pin respectively extending from a top of the base. The post is received in a hollow column on which a motor is connected. The column has two positioning passages so that the positioning pin is engaged one of the positioning passages. A frame is connected a side of the column and a pusher is connected to the frame. A rod extends from the pusher and a pressing member is movably mounted to the rod. When rotating the column 180 degrees about the post, the column is conveniently positioned by inserting the pin with the other positioning passage.

Abstract: Footwear comprising a sole, an upper, and a lace-binding system comprising a plurality of replaceable eyelet extenders. Replacing eyelet extenders, or components thereof, with others of a different color facilitates switching footwear from one color pattern to another. Replacing eyelet extenders, or components thereof, with others of a different length, flexibility, or elasticity facilitates modifying flexibility between eyelets and lace.

Abstract: An automatically rewindable wire device includes a stationary member having a stationary shaft, and a rotary member mounted rotatably on the stationary member and having a windup portion around the shaft. The windup portion and the shaft confine a space. The windup portion has an opening which is communicated with the space and which is spaced apart radially from the shaft. The device further includes a wire having a first portion fixed to the stationary member and a second portion extending outwardly of the stationary member from the first portion of the wire. The second portion of the wire is wound around the shaft in a first angular direction within the space and then wound around the windup portion in a second angular direction by passing through the opening. The second angular direction is opposite to the first angular direction. A windup spring is connected to the rotary member to urge the windup portion to wind up the wire.
