Abstract: A self width-adjusting device holder comprises two width-adjustable side walls or plates, a stopper a resilient width-adjustment mechanism and a base plate. The two width-adjustable side plates are adapted to be pushed away from each other when a device is inserted and to automatically move toward each another or retract when a device is removed from the holder. The width-adjustable plates may be slidably mounted on the base plate. As these two side plates slide, the receiving area may be adjusted to be adapted to the devices with different sizes.

Abstract: A head-mounted support device for carrying at least one un-inflated inflatable or expandable inner portion of an in-ear device thereon includes a main body adjustably mountable on a user's head, with at least one settable compound delivery device mounted thereon, and a at least one receptacle to receive an inflatable in-ear device inner portion. The invention also refers to a head-mounted settable compound delivery system kit, along with the earphone wire assembly that receives the customized in-ear device inner portions thereon.

Abstract: A digital multi range liquid level detector to verify and maintain a predetermined level in a container. The level is measured by a capacitive sensor located above or in the liquid to be maintained. The capacitive sensor is composed of a pair of probe connected to a signal converter chip to obtain a digital data. The digital data is then compared to a reference value obtain during the initial calibration. The present invention is composed of two paired components, a capacitive digital sensor and a fluid control valve that can be installed at different locations. The sensor determines the liquid level and then transmits the acquired data to the fluid valve control receiver via wire or radio frequency (RF). The sensor and valve are programmable in order to evaluate different possibilities such as water level, water activities and recurring low level demands. They can also be reprogrammed.

Abstract: A lighting system is described. The lighting system includes a substantially round lens, a base, a circuit board and an adaptor. The lens has an exterior side and an interior side. The base has a first side and a second side. The base is sealingly coupled to the interior side of the lens to create a watertight compartment therebetween. The second side of the base has at least one connector member. The circuit board is coupled to the first side of the base. The circuit board implements a circuit including a plurality of light emitting diodes (“LEDs”) and a power supply receiving connector. The power supply receiving connector is accessible through the second side of the base. The adaptor has a first side configured to interface with the at least one connector member and a second side having a threaded coupling to maintain the lighting system in a fixed position in a fitting.
