A mop disc and fabric frame fixation structure includes a fabric frame including cotton strips at the bottom of the fabric frame, a noncircular embedding concave surface at the top of the fabric frame, latch bumps formed in the corresponding embedding concave surface and protruded upwardly, and a concave latch surface concavely formed on at least one side of the latch bump. A disc is embedded into the embedding concave surface and has a latch groove in the corresponding embedding concave surface. Each latch groove is arranged apart from the other. A latch block is formed on an internal wall of the latch groove and protrudes from the corresponding concave latch surface. Thus, the disc is embedded into the embedding concave surface, and the concave latch surface and the latch block are latched with each other, to combine the fabric frame to the disc.

A pool guard alarm apparatus includes an alarm body, a triggering device and a relative triggering element. The alarm body accommodates a circuit board and a battery for providing a power source. The circuit board is provided with several buttons and a sound member. The buttons enable an authorized person to bypass the alarm mode. The triggering device located at the entrance to the pool has a movable part which is elastic to be against the relative triggering element. The moveable part will produce a triggering signal to the circuit board when the entrance is opened. The circuit board activates the sound member to produce an alarm sound after a predetermined time. The alarm sound is repeated after a period of time while in the alarm mode. When the entrance is then closed, the user must reset a pass code to activate the said alarm mode.

The present invention provides an improving design of a portable radar alarm device that comprises a cover body and a launching device. The portable radar alarm device of the present invention sorts out those defects of the conventional alarm device. The present invention provides the portable radar alarm device controlled by a re-set remote-control device can be setup quickly and easily at a location of outdoor sports or wildlife activities. Once the sensor of the alarm device senses any abnormal condition, a warning signal will be sent to a user to warn the potential danger. Thus, the present invention provides an improving design of an alarm device that is more practical to accompany the needs of outdoor activities, is convenient to use and easy to setup and position the device.

New photosensitive optically variable inks are capable of printing images having improved resistance to water. The inks produce images which can be viewed with both visible and ultraviolet light to have physically coincident positive and negative images. They contain at least two types of colorants and other suitable ingredients to enable preparation for printing. The first colorant comprises a fluorescent dye emitting light within a characteristic emission band when excited by fluorescent-exciting radiation. The second colorant, which comprises a colloidal pigment alone or with a dye, has a light absorption band at longer wavelengths than the characteristic emission band of the first colorant or overlapping the emission wavelength of the first colorant, effectively to result in a dark color. The composition also contains an aqueous liquid vehicle comprising water and a water-soluble vehicle in sufficient amounts to achieve an ink viscosity and surface tension effective for application of the ink to a substrate in a predetermined pattern by ink jet printing.
