Abstract: A golf ball scriber includes: a clip comprising a first clip body and a second clip body which are connected by a pivot shaft; a clamping groove surface disposed on an inner clamping surface of the clip; a sealed brush device; a first clip groove and a second clip groove symmetrically arranged on a respective outer wall of the first clip body and the second clip body; a scribing ruler disposed at a bottom surface of the first clip groove; a strip-shaped chamfered groove disposed on the scribing ruler away from the clamping groove surface; and a strip-shaped scribing groove disposed on the chamfered groove which corresponds to the clamping groove surface, wherein the scribing ruler, the chamfered groove, and the scribing groove share a central line, and the brush device is in sliding connection with the first clip groove disposed on the first clip body.

Abstract: A combustion system including a combustion mechanism that injects oxygenated fuel into a combustion chamber. The oxygenated fuel mixes with the intake air in the combustion chamber where the air-fuel ratio in a portion of the combustion chamber is stoichiometric. The combustion mechanism includes an ignition mechanism that ignites the air-fuel mixture that generates a threshold number of particulates during combustion of the air-fuel mixture. The combustion system further includes an exhaust gas recirculation (EGR) device that recirculates a portion of the exhaust gases back into the combustion chamber. The EGR device recirculates the portion of the exhaust to lower combustion temperature resulting in reduced amount of nitrogen oxide in the exhaust. The combustion system further includes a three-way catalytic converter in line with the exhaust channel to convert a second portion of the exhaust gases, leading to lower pollutant emissions than conventional combustion systems.

Abstract: A golf ball scriber includes: a clip comprising a first clip body and a second clip body which are connected by a pivot shaft; a clamping groove surface disposed on an inner clamping surface of the clip; a sealed brush device; a first clip groove and a second clip groove symmetrically arranged on a respective outer wall of the first clip body and the second clip body; a scribing ruler disposed at a bottom surface of the first clip groove; a strip-shaped chamfered groove disposed on the scribing ruler away from the clamping groove surface; and a strip-shaped scribing groove disposed on the chamfered groove which corresponds to the clamping groove surface, wherein the scribing ruler, the chamfered groove, and the scribing groove share a central line, and the brush device is in sliding connection with the first clip groove disposed on the first clip body.

Abstract: A nail lamp device includes an inner housing having an inner housing substrate and an inner chamber surrounded by the inner housing substrate, at least one chip on board (COB) light emitting diode (LED) module disposed on an inner surface of the inner housing substrate by pasting-fitted and emitting light toward the inner chamber, a control module disposed on an outer surface of the inner housing substrate and electrically connected to the COB LED module, and an outer housing covering the inner housing and retaining a front opening of the inner chamber exposed. The COB LED module used by the nail lamp device is directly disposed on the inner surface of the inner housing substrate by pasting-fitted and has a plurality of LED elements arranged in array to accelerate the time required for the curing reaction of the resin coatings or glues coated on fingers. Moreover, the wavelength ranges of light can be selected with high elasticity, so as to enhance utility.

Abstract: A lens cap for a camera is disclosed, comprising: a reference surface, the reference surface having the capability of being used to calibrate an exposure setting or a white balance setting of a photographic subject; wherein the lens cap is placed in front of a lens of the camera in the lighting conditions of the photographic subject, the reference surface being directed towards the lens; and wherein an intensity of the visible light spectrum being reflected by the reference surface is detected.
