    Abstract: A digital color clock uses Color Digits instead of Roman or Arabic numerals. Each Color Digit is capable of displaying a unique color corresponding to one of the ten Arabic numerals (0-9). Preferably the clock contains at least six Color Digits grouped into three pairs. One of the pairs corresponds to hours, another of the pairs corresponds to minutes, and the remaining of the pairs corresponds to seconds. The three pairs can be separated by unit separators. Both the unit separators and the Color Digits can be illuminated using red/green/blue light-emitting diodes. In one embodiment, the Color Digits are interspersed among other unchangeable color panels. In another embodiment, the digital clock senses and displays the temperature, humidity, and/or date using Color Digits.

    Abstract: A radio-controlled clock (RCC) for receiving and decoding a transmitted time signal to display a precise time in accordance with a time standard. A light emitting diode (LED) display emits sufficient light for easy readability under all lighting conditions, including the time numerals. A signal reception indicator remains lit if the RCC has successfully decoded a time signal. If the time signal is currently being received and decoded, the signal reception indicator flashes. If the decoding is unsuccessful, the signal reception indicator will be unlit until the next decoding attempt. A power transformer to supply current to electronic circuitry contained within in the housing of the RCC is located in the power line cord, as at the plug end, to minimize electromagnetic interference with the decoding of the time signals. A signal strength indicator may have multiple segments to indicate if the received signal is strong, medium, weak or too weak for decoding.

    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.

A display device and the like include a polarizer, a liquid crystal layer, a polarization separating film, and a solar battery. The polarization separating film operates to transmit linearly polarized light polarized in one direction and to reflect other linearly polarized light. Since the surface of the solar battery has a dark color, such as black, a dark-colored background is displayed by light traveling along an optical path. Information, such as numbers, is displayed in a light reflection color by light that is reflected by the polarization separating film and travels along an optical path. The information, such as numbers, is displayed in a light reflection color.

  • Patent number: 4205518
    Abstract: A voltage conversion system for an electronic timepiece having a power source, which system generates power at lower voltage level than that of the power source for operating at least one of a frequency standard, a frequency converter, a time counter circuit and a display system. The voltage conversion system comprises an oscillator circuit coupled to the power source to generate output signals, a plurality of capacitors, and a plurality of switching elements responsive to the output signals for alternately setting the capacitors in a parallel connected condition and a series connected condition, whereby an output voltage lower than that of the power source is generated at an output terminal of the system.

  • Patent number: 4202235
    Abstract: An electronic musical box is disclosed in which a musical score can be readily stored and reproduced and the musical score can be easily changed to another. The musical box includes a pulse generator for generating a unitary pulse for a note whose duration is the shortest in the musical score and generating integer numbers of unitary pulses for other notes in the musical score. A tone pitch generating circuit generates tone pitch signals coded by a plurality of tone pitch switches so as to correspond to the tone pitches of the notes in the musical score. The coded tone pitch signals are stored in a memory, and a musical tone generating circuit reads data stored in the memory and generates musical tones.
