| 20080205201 | Time display apparatus - A time display apparatus is disclosed and comprises at least a housing, a timetable panel, three pointers and a backlight unit. The timetable panel is disposed in the housing. The three pointers are coated with variety of phosphorescence materials respectively and vertically arranged on the timetable panel in order. The backlight unit is disposed below the timetable panel to generate a light source with a fixed wavelength to illuminate the phosphorescence materials of the three pointers, thereby generating different colors for showing hour, minute and second respectively. | 08-28-2008 |
| 20090080293 | CLOCK HAVING AN ELECTROLUMINESCENT LIGHT (EL) FACE PLATE AND METHOD THEREFOR - An electroluminescent (EL) clock has a face plate. An EL light panel is coupled to a front surface of the face plate. The EL light panel has a multi-color/sectional design. A control circuit is coupled to the EL light panel and attached to a rear surface of the face plate. The control circuit is used to individually control the lighting of each color/section of the multi-color/sectional design. A pair of clock hands is rotatably coupled to the face plate. A clock control device is coupled to the pair of clock hands to rotate the pair of clock hands. A power supply is coupled to the control circuit and the cock control device. | 03-26-2009 |
| 20100074061 | Multifunction Time Display Device - A multifunction time display device includes a main body, a first element, a second element, and an indication element. The main body includes a casing, and the casing possesses a transparent portion. The first element moves inside the casing as time goes by. The second element is removably attached to any position of the transparent portion of the casing. The indication element is triggered when the first element moves to overlap the second element. | 03-25-2010 |
| 20100202255 | TIMEPIECE FITTED WITH A LIGHTING DEVICE COMPRISING AN ULTRAVIOLET LIGHT-EMITTING DIODE - The invention relates to a timepiece ( | 08-12-2010 |
| 20110075524 | TIME DISPLAY DEVICE AND TIME DISPLAY METHOD THEREOF - A time display device comprises a dial plate; a plurality of time indication portions set in the dial plate; and a plurality of groups of luminophors. Each of the groups of luminophors corresponds to a time indication portion, and comprises a first luminophor, a second luminophor, and a third luminophor. A clock unit provides current time information. A first switch unit electrifies/powers off the first luminophor. A second switch unit electrifies/powers off the second luminophor. A third switch unit electrifies/powers off the third luminophor. A hour hand controlling module obtains a hour value, and controls the first switch unit to electrify the first luminophor of the time indication portion corresponding to the obtained hour value. A minute hand controlling module obtains the current minute value, and controls the second switch and/or the third switch unit to electrify the corresponding luminophor. | 03-31-2011 |
| 20110158056 | Dual Illumination Watch Face, And Associated Methods - Systems and methods for a dual illumination watch face having a tritium gas tube coupled with a dial, minute hand or hour hand of the watch face, and phosphorescent material disposed with at least one of the dial, minute hand and hour hand. | 06-30-2011 |
| 20120263022 | WRISTWATCH - A Wristwatch having a housing ( | 10-18-2012 |
| 20140160904 | METHOD AND SYSTEM FOR AUTHENTICATING A TIMEPIECE - A timepiece including at least dial, at least one hand mounted on the timepiece and having an upper side and a lower side facing the dial, and a security material arranged on the lower side of the at least one hand. The security material includes a medium containing one or more compounds having luminescent properties in the infrared (IR) range of the electromagnetic spectrum. | 06-12-2014 |
| 20150029829 | Timepiece Comprising An Analog Display and a Digital Display - The present invention relates to a watch, comprising: a frame ( | 01-29-2015 |
