Patent number: 7170019Abstract: Inertia switches in insulating housings are used to make or break electrical contact. The switches may be small in size, and may be used with flashing light systems in footwear or other articles. One embodiment is a directional switch sensitive to the orientation of the switch and the motion of the switch due to outside forces. Footwear with flashing light systems that use these inertia switches may make the wearer or user more visible at night, adding a measure of safety as well as fun. Flashing light systems using these inertia switches may also be used to illuminate personal accessories and articles of clothing.Type: GrantFiled: July 14, 2003Date of Patent: January 30, 2007Assignee: Cheerine Development (Hong Kong), Ltd.Inventors: Wai Kai Wong, Lai Cheong Mak

Patent number: 7059739Abstract: An illuminating device with flashing lights may is adjustably affixable to ice skates or in-line skates. The illuminating device may include a number of lamps or light emitting diodes (LEDs) and is controlled by a motion switch or other switch. The lamps or LEDs are visible from the inside of a transparent box which is installed in the hollow between the shoe portion of the skate and the blade or wheels of the skate. The illuminating device is necessarily compact in nature, consisting primarily of flashing lights and a power-and-control circuit that controls and enables the flashing of the lights. The lights may be flashed sequentially, in-phase, randomly, or in other desirable patterns.Type: GrantFiled: October 17, 2002Date of Patent: June 13, 2006Assignee: Cheerine Development (Hong Kong) Ltd.Inventor: Wai Kai Wong

Patent number: 7029140Abstract: Flashing lights may be added to footwear or other objects worn by persons. Flashing light systems are necessarily compact, consisting primarily of flashing lights and a power-and-control circuit that controls and enables the flashing of the lights. The lights may be illuminated by differing voltage levels, so that lights will flash brighter or dimmer depending on whether the light receives a higher voltage or a lower voltage. The voltages may be achieved by using batteries in series. A unique flashing effect is achieved by the use of differing voltages in sequence on the same lamps or LEDs. A battery charger may also be included to restore battery life.Type: GrantFiled: December 23, 2003Date of Patent: April 18, 2006Assignee: Cheerine Development (Hong Kong) Ltd.Inventors: Wai Kai Wong, Lai Cheong Mak

Patent number: 7004598Abstract: Illuminating devices may be added to footwear or other objects worn by persons. The illuminating devices are necessarily compact in nature, consisting primarily of flashing lights and a power-and-control circuit that controls and enables the flashing of the lights. The lights may be illuminated by differing voltage levels, so that lights will flash brighter or dimmer, in sequence, depending on whether the light receives a higher voltage or a lower voltage. The voltages may be achieved by using batteries in series. A unique flashing effect is achieved by the use of differing voltages in sequence on the same lamps or LEDs. A battery charger may also be included to restore battery life.Type: GrantFiled: February 18, 2003Date of Patent: February 28, 2006Assignee: Cheerine Development (Hong Kong) Ltd.Inventor: Wai Kai Wong

Patent number: 6906472Abstract: Illuminating devices may be added to clothing and accessories worn by persons. Articles to which the illuminating devices may be added include footwear, hair-control articles, belts, suspenders, backpacks, purses, book-bags, vests and the like. The illuminating devices are necessarily compact in nature, consisting primarily of flashing lights and a power-and-control circuit that controls and enables the flashing of the lights. The lights may be flashed sequentially, in-phase, randomly, or in other desirable patterns, and the lights may also fade-on or fade-off. Controls may include an inertial switch, a push-button or touch-switch, and an on-off toggle switch.Type: GrantFiled: September 4, 2002Date of Patent: June 14, 2005Assignee: Cheerine Development (Hong Kong) Ltd.Inventor: Wai Kai Wong

Patent number: 6851817Abstract: A wheel incorporating a flashing light feature includes a power source, a plurality of lighting elements and a flashing circuit to selectively provide lighting signals to the plurality of lighting elements. The wheel incorporating a flashing light feature further includes at least two motion switches to activate the flashing circuit. The at least two motion switches include a spring having a fixed end and a free end and a metal cap positioned proximate the free end of the spring for electrical engagement by the free end of the spring. Examples of articles with a wheel incorporating a flashing light feature include scooters, roller skates, in line skates, roller shoes and other types of wheeled footwear.Type: GrantFiled: November 4, 2002Date of Patent: February 8, 2005Assignee: Cheerine Development (Hong Kong) Ltd.Inventor: Wai Kai Wong

Patent number: 5969479Abstract: A light-flashing system for flashing lights on and off and for generating a pattern of illumination for a plurality of lights in response to intermittent switch closures. The system includes a battery, a plurality of light-emitting elements, a plurality of transistors which enable the illumination of the light-emitting elements, a switch, a capacitor, and a pattern-generation circuit. The battery powers the light-emitting elements and the pattern-generation circuit. The switch intermittently clocks the pattern-generation circuit and enables the flow of current in certain of the transistors, allowing illumination of certain of the light-emitting elements in response to changes in inertial forces caused by movement of the flashing light system. The capacitor is connected in parallel to the battery such that the capacitor stores electrical charge when the switch is closed and continues to enable the flow of current through certain of the transistors after the switch is opened.Type: GrantFiled: March 10, 1998Date of Patent: October 19, 1999Assignee: Cheerine Development (Hong Kong) Ltd.Inventor: Wai Kai Wong
