  • Patent number: 6683822
    Abstract: The invention provides an enhanced structure of a time display device includes a circle with 60 display units on the circumference of the clock face, among which 12 display units are made larger for displaying hour of time (hour display units) and the rest (smaller ones) displaying minute of time (minute display units). The display units are made with materials that shine or flicker to indicate time in the dark. To indicate hour of time, a given hour display unit and the two minute display units right next to this hour display unit would be switched on. To indicate minute of time, one of the minute display units would be switched on. While a given display unit has to indicate hour and minute at the same time, it flickers.

  • Patent number: 6388642
    Abstract: A bidirectional multispeed indexing control system for a display unit which has an increment input and a decrement input so as to be controllable to sequentially index through an ordered list of discrete elements. The control system has a two-button user interface. The user presses one button to increment once, and holds that button to continuously index at a slow fixed speed. To increase the indexing speed, the user presses the second button while continuing to hold the first button. Indexing speed will continue to increase until either a maximum speed is reached or the user releases the second button, at which point the indexing speed decreases from the value reached while holding the second button. To stop indexing, both buttons are released. To increment in the opposite direction (i.e., decrement), the order in which the buttons are pressed is reversed.

  • Patent number: 5917779
    Abstract: A transformerless oven timer which uses a 20 pin microcontroller connected to light emitting diodes. The microcontroller has 2 Kbytes of 8 bit read only memory and has software etched therein. The microcontroller can transfer power and voltage to the light emitting diodes when the oven is connected to, and powered by, an electrical outlet. The software etched into the microcontroller detects whether a resistor is connected to the microcontroller and converts a pin on the microcontroller from an input into an output. The software also synchronizes the microcontroller with the frequency of the electrical outlet to provide that the microcontroller keeps track of time. The transformerless oven timer also includes electrical circuitry connected to the microcontroller, where the electrical circuitry reduces the voltage and current provided to the microcontroller and to the light emitting diodes without using a transformer.

  • Patent number: 5896348
    Abstract: A novel method or convention of tracking and displaying the passage of time can be implemented in a variety of decorative and interesting timepiece configurations. Three groups of indicators are used. Each group of indicators is distinguishable from the other two groups. Each indicator is capable of displaying one of two states and can be readily switched between the two states. The first group consists of twelve indicators with the number of indicators in one of the two states being indicative of the hour. The second group consists of five indicators with the number of indicators in one of the two states being indicative of the passage of a multiple of ten minutes. The third group consists of nine indicators with the number of indicators in one of the two states being indicative of the passage of a minute. In this manner, the current time is indicated.

  • Patent number: 5410520
    Abstract: A timepiece combines benefits of analog and digital displays in a format that is both easy to read and precise. The face of the timepiece includes a plurality of selectably displayable LCD numbers spaced about its periphery. Driving circuitry activates certain of the numbers to provide digital readouts of the hour and the minute along the periphery of the face at the angular positions conventionally corresponding thereto. Simulated analog hands can be provided as well. At 3:37, for example, the numbers 3 and 37 are activated on the periphery of the timepiece off the ends of the simulated hour and minute hands, respectively. The angular positioning of the activated peripheral numbers provides a readily discerned spatial impression of time; the numerals themselves provide digital accuracy.
