摘要:
A portable electronic device includes a system chip, an enabling switch, a signal conversion circuit, a power switching circuit, a storage medium and a synchronous processing module. The enabling switch is triggered to issue an analog signal. The signal conversion circuit converts the analog signal into a digital control signal. The power switching circuit selects one of multiple power sources to be outputted as a voltage signal. The storage medium receives the voltage signal. The synchronous processing module is electrically connected to the system chip, the storage medium, the signal conversion circuit, the power switching circuit and the transmission line. In response to the digital control signal, the storage medium is communicated with an external electronic device through a transmission line, so that the storage medium of the portable electronic device is used as an external storage medium of the external electronic device.

A golf swing/putting trainer includes a support member including a body shaped like a plate or shaft and having a supporting wall for stopping against the user's body, and a handle including a shaft connected at one end thereof to the center of the body of the support member and having a handhold portion for holding by the user's both hands. Thus, the user can hold the handle with the two hands to abut the supporting wall of the support member against the abdomen, and then twist the waist to practice the backswing and swing actions. Alternatively, the user can hold the handle with the two hands and attach the two lower arms to the two bearing portions of the support member to practice the putting action.

A hand grip sleeve for wrapping about a grip of a golf putter includes a flexible sleeve defining a sleeve hole extending from the front end to the rear end and a longitudinal opening cut through the peripheral wall, and a fastener provided at the flexible sleeve at two opposite sides of the longitudinal opening and operable to open or close the longitudinal opening. The fastener may be a hook and loop fastener, a zipper or snaps. Thus, the hand grip sleeve can be directly and conveniently attached to the grip of a golf putter to increase the diameter of the grip area of the golf putter for gripping tightly and comfortably. By means of the design of the longitudinal opening and the fastener, a user can easily install the hand grip sleeve on the grip of a golf putter.

A golf putter includes a putter head comprising a putter block and an aiming block and a shaft fixedly connected to the putter block. The putter block includes a putting face on one side for putting a golf ball, a mounting portion on an opposite side for the mounting of the aiming block. The aiming block is a transparent block affixed to the mounting portion of the putter block, carrying an aiming mark that guides the player to put the golf ball accurately. In another embodiment, a golf putter includes a transparent putter head and a shaft connected to the putter head; and the putter head has a putting face on one side and an aiming mark on an opposite side.
