  • Patent number: 8654616
    Abstract: A visual alert device includes a keypad for a user to enter a primary follow-up time period for which a user desires to be visually reminded of its progressive expiration. Based on the entered primary follow-up time period, the visual alert device computes a preliminary and a final follow-up time value, which are associated with a level of response priority that is visually represented by the illumination of corresponding illuminable color segments. Thus, when a timer of the visual alert device reaches each of the preliminary follow-up time value, the primary follow-up time period, and the final follow-up time value, the corresponding color segments are illuminated to indicate the current response priority level.

  • Patent number: 6871407
    Abstract: This invention represents an improvement to an equatorial sundial comprising an independent simultaneous single scale indication of both time and date as represented from a primary and secondary gnomon. This allows one unfamiliar with the physics of an equatorial sundial to with simple observation quickly assess both time and date as a singular measurement. The sundial displays conventional time measurement on a single scale transcribed on the equatorial ring from a primary gnomon aligned with the polar axis. The improvement includes a date scale transcribed on the primary gnomon that is cast a shadow from the secondary gnomon comprised of the upper equatorial ring. Since the sun maintains an essentially equivalent angle of declination throughout the day, the shadow cast by the upper equatorial ring (secondary gnomon) on the primary gnomon (containing the date scale) remains consistent in position and date can be observed at any time of the solar day.

  • Patent number: 4834475
    Abstract: In an analogue indicating device (e.g. a clock) in which the relative positions of two relatively movable components (FIGS. 1-3; 26/28 and 12) is judged by the position of a reference marker (30/32) on one of the components (26/28) in relation to an adjacent scale (48) on the other component (12), the scale is constituted by a hologram (in 12) which when illuminated by a predetermined reference light (33) portrays a desired image of the scale (48) against which the reference marker (26/28) is seen. That image may also portray an environment (34) (e.g. a clock case) in which the scale (48) appears to be contained. The reference marker (26/28) may also be constituted by a hologram for portraying a holographic image of the reference marker. Alternatively, a holographically portrayed reference marker may cooperate with a real scale. The holographically produced image is preferably coplanar with the other image, whether the latter image be real or holographically produced, so as to elliminate parallax errors.

  • Patent number: 4253170
    Abstract: A light fixture which indicates the time of day includes a clock mechanism having a movable hand and an electrically operated illumination device arranged relative to the clock mechanism for casting a shadow of the hand on a surface. A light sensing device senses the ambient light intensity at the fixture location and it is operatively connected to the illumination device to increase the intensity of the illumination device in response to an increase in ambient light intensity and to decrease the intensity of the illumination device in response to a decrease in ambient light intensity.

  • Patent number: 4228346
    Abstract: A clock circuit designed to keep time based upon a known frequency of an alternating current power supply is provided with a d.c. power backup system to operate the clock circuit during periods of a.c. power failure. The clock circuit includes a high frequency oscillator which generates a large number of timing pulses for each alternating current power cycle. During periods of normal operation on alternating current power, the number of oscillator timing pulses occurring between successive null points in the alternating current power supply waveform are counted and stored. When the clock circuit is operated from the d.c. power supply during periods of a.c. power failure, the last count of timing pulses between successive null points in the a.c. cycle is loaded as an initial count into a counter. The counter is decremented down to zero, whereupon the counter registers the passage of a period of time corresponding to the time interval between two null points in the a.c.

  • Patent number: 4207731
    Abstract: An electronic timepiece control circuit for facilitating the selection of a preferred function in a multi-functional electronic timekeeping circuit wherein each function can also be selected cyclicly in sequence, is provided. The timekeeping circuit is adapted to be disposed in at least three timekeeping functional modes to perform at least one distinct timekeeping function in each functional mode in response to a function control signal being applied thereto. Mode select circuitry is coupled to the timekeeping circuit for cyclicly selecting, in sequence, each timekeeping functional mode of the timekeeping circuit in response to each mode select signal applied thereto. A judgment circuit is coupled to thetimekeeping circuit and is adapted to return the timekeeping circuit to a predetermined timekeeping functional mode in response to a mode select signal and a function control signal being coincidentally applied thereto.
