Abstract: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: A backlight module includes a light-emitting unit, and a controller to receive a first control signal and generate a second control signal to control the light-emitting unit. The controller controls a frequency of the second control signal according to a duty cycle of the first control signal.

Abstract: An internal combustion engine comprises multiple cylinder blocks in series rotatablely mounted in a single casing. The cylinder blocks each define multiple cylinders along a circumferential portion of the cylinder block to receive a piston in each one. The casing forms multiple spark plug holes and defines multiple exhaust ports and multiple intake ports in the periphery thereof. Each the cylinders is accessible to the spark plugs, the exhaust ports and the intake ports upon rotation of the cylinder block. The spark plugs, the exhaust ports and the intake ports of various cylinder blocks are staggered.

Abstract: A rotary combustion engine construction includes an engine block (20) defining a cylindrical inner space (22) in which a toothed ring portion is integrally attached with the engine block (20), and a cylindrical block (40) rotatably and snugly fitted in the cylindrical inner space (22) of the engine block (20). A number of spark plugs (30) are installed on the engine block (20) at angular intervals.

Abstract: An exerciser includes a weighted base, a frame member, a resistance assembly mounted in the frame member, and a lifting bar mechanism. The lifting bar mechanism includes an axle rotatably mounted in the frame member, a gear securely mounted on the axle, a lifting bar connected to the axle to rotate therewith, a clutch seat mounted on the axle surrounding and receiving the gear and having a cutout in a periphery thereof, a rocker arm extending outward from an outer periphery of the clutch seat, a cable having a first end attached to the rocker arm and a second end attached to the resistance assembly, and a clutch assembly with a pawl member for releasably engaging with the gear under the control of a clutch lever thereof. When the clutch lever is pressed, the user may adjust the lowermost position of the lifting bar.

Abstract: An exerciser includes a weighted base, a pair of spaced vertical beams, a resistance assembly mounted in each vertical beam, a lifting bar with two ends thereof respectively and removably mounted to each resistance assembly at a desired height, and a foldable bench.
