A battery-charging device, having a maximum power point tracking (MPPT) function, for a stand-alone generator system includes a DC/DC power converter and a control circuit used to control the DC/DC power converter. The method applied in the device includes: performing a MPPT function to supply a continuous current when the electric power generated from the electrical power source of the stand-alone generator system is low; operating a pulse charging function and continuing the MPPT function when the electric power generated from the electrical power source of the stand-alone generator system is high and not greater than the summation of the load power and a maximum charging power of the pulse charging method for the battery; terminating the MPPT function while the electric power is greater than the summation of the load power and the maximum charging power of the pulse charging method for the battery; and operating a constant-voltage charging mode when the battery voltage is greater than a predetermined constant charging voltage.

A collapsible eyeglass structure includes a frame bilaterally provided with two temples. The frame has two ends, each having an inner side formed with a through hole. Each through hole has an entrance end with a beveled rim and an opposite end connected to an inwardly expanding receiving space. Each receiving space has a predetermined shape and an upper wall formed with plural teeth. Each temple has a pivotal connecting portion outwardly extended with a post. Each post has a convex tip and is notched so as to be pushed resiliently into the corresponding through hole of the frame. Each post further has an upper periphery formed with a tooth. When the posts are pushed into the receiving spaces in the frame respectively, the tooth of each post meshes with the corresponding teeth in the corresponding receiving space to allow angular adjustment or downward collapse of the temples.

An effort-saving hand tool includes a first shaft, a second shaft, a connection shaft, and a third shaft. The first shaft has a first end, a second end, and a pivot point located between the first end and the second end. The second end of the first shaft includes a first loading part. The second shaft has a first end and a second end. The pivot point of the first shaft is pivoted to the first end of the second shaft. The second end of the second shaft includes a second loading part. The connection shaft has a first end pivoted to the first shaft. The third shaft has a slender rear part, a first side, and a second side. The first side of the third shaft is pivoted to the second shaft. The second side of the third shaft is pivoted to a second end of the connection shaft.

A method for an image adjustment is disclosed. The method comprises the steps of: reading an interested pixel and its plural neighboring pixels from an image storage device; determining a so-called first gradient value of the first direction and a so-called second gradient value of the second direction, wherein the first direction is the orthogonal direction of the second direction; comparing the first and the second gradient values; executing a sharpness adjustment to the interested pixel along the direction which has larger gradient value; then executing a noise reduction or smoothing adjustment to the interested pixel along the direction which has smaller gradient value; and repeating the steps until all interested pixels are processed and obtaining a new pixel value.

A yoga brick includes first and second casings. Each of the first and second casings includes inner and outer faces spaced along a first axis, a peripheral wall extending between the inner and outer faces, and a first recessed portion formed in the outer face. The first recessed portion includes a wavy holding face having a plurality of anti-slipping ribs. Each of the first and second casings can further include a second recessed portion formed in the outer face thereof. The second recessed portion includes a wavy holding face having a plurality of anti-slipping ribs. The first and second casings can be engaged with each other with the first recessed portion of the first casing aligned with the second recessed portion of the second casing along the first axis and with the second recessed portion of the first casing aligned with the first recessed portion of the second casing along the first axis.

An effort-saving stapler includes a first activating mechanism including a first connecting section and an abutting ridge, and a second activating mechanism including a ram and an arm including a second connecting section pivotally connecting to the first connecting section at a fulcrum point “A”. The stapler further includes a pushing mechanism including a third connecting section, an anvil, and an abutting ridge contacting with the abutting edge of the first activating mechanism, and with these two abutting ridges defining a contact point “B”. The stapler further includes a magazine including a fourth connecting section pivotally connected to the third connecting section at a second fulcrum point “C”. The fulcrum point “A”, contact point “B” and fulcrum point “C” are in a straight line when bending legs of the staples for closing the staples in an effort-saving way.
