  • Patent number: 8115121
    Abstract: A timer includes a case, a shaft, a cam wheel, a drive mechanism, and a plurality of switch blades disposed within the case. The shaft is rotatably and reciprocally movably disposed in the case. The cam wheel is pivoted on the shaft and rotates together with the shaft when setting, or rotates independently by the drive mechanism. The cam wheel includes a plurality of cam tracks on one side surface thereof and a plurality of ratchets and grooves on a circular rim thereof. The drive mechanism contacts the ratchets to drive the cam wheel to rotate relative to the shaft. The switch blades respectively contact the cam tracks of the cam wheel, and correspondingly generate an electrical connection/disconnection. When the shaft moves to the setting position and the cam wheel being rotated by the user, a flexible element touches the grooves formed on the circular rim results a tactile feedback.

  • Publication number: 20090038924
    Abstract: An automatic timing switch device includes a switch control wheel, a driving assembly, and a plurality of push switches. The switch control wheel includes a plurality of wheel-shaped structures stacked sequentially, wherein each of the wheel-shaped structures has at least one notch formed on an outer periphery of the switch control wheel, and the diameters of the wheel-shaped structures reduce sequentially so that the switch control wheel is in tapered shape. The driving assembly drives the switch control wheel to rotate. The push switches are switched by engaging into or separating from the notches of the wheel-shaped structures as the switch control wheel rotated by the driving assembly. Since the switch control wheel is in a tapered shape, so that the switch control wheel is easily to be formed monolithically and is convenient to be installed to the case of the automatic timing switch device.

  • Patent number: 7050707
    Abstract: A heater device applied in a desiccant rotor dehumidifier for supplying regeneration hot air to the desiccant rotor comprises a metal case having an air inlet and an air outlet; heating elements supported by insulative material and mounted adjacent to the desiccant rotor; and an insulative plate installed in parallel to the heating elements and parting the heating elements with the air inlet. The insulative plate is formed with a plurality of via holes suitably distributed for the intake air coming from the air inlet passing through, being heated by the heating elements and evenly passing the desiccant rotor through the air outlet. The insulative plate also splits and bypasses a part of the intake air to cool down the desiccant rotor that has been heated and regenerated.

  • Patent number: 6727440
    Abstract: An electromechanical program timer provides at least a section with a slower timing speed besides a major timing speed. The timer includes a driving motor rotationally drives a driving shaft. A driving gear and an eccentric shaft are formed on the driving shaft for driving a cam disk through a main driven gear and via a pushing pawl to a driven ratchet respectively. The main driven gear includes at least a missing gear portion where the driving gear is free from driving the main driven gear, and the pushing pawl and the driven ratchet take place. The driving shaft engages and rotates the cam disk through the main driven gear in a major timing speed. While at the missing gear portion, the eccentric shaft oscillates the pushing pawl and drives the cam disk through the driven ratchet step by step in a reduced timing speed.

  • Patent number: 5262837
    Abstract: A method and an apparatus for measuring the distance to a target according to the time-of-flight of laser pulses. The apparatus includes a transmitter of laser impulses toward the target and a receiver of laser impulses reflected from the target. A driver of the transmitter generates a first time signal corresponding to the transmission. The receiver generates a second time signal corresponding to the reception. A delay generator delays at least one of the first and second signals to compensate for time errors, and provides a third signal corresponding to the first signal and a fourth signal corresponding to the second signal, such that a time difference between the third and fourth signals is exactly equal to the time-of-flight of the transmitted pulses.

  • Patent number: 5260691
    Abstract: A combination fire alarm/air conditioner, which can immediately detect a fire. The device includes a temperature-sensor and/or a smoke-sensor installed in the room-side air inlet of the air conditioner. Signals generated by the sensor are received by a microcomputer which monitors them based on a threshold and a rate of change of the signals. When the rate of change of the signals exceeds the threshold, the microcomputer produces signals which set off an alarm.

  • Patent number: 5254909
    Abstract: A device for modulating and controlling the level of luminosity output by a lighting facility. The modulation may be of average current or voltage. The device modulates electrical power in a cyclical manner for input to the lighting facility, so that the resulting modulation of the luminosity output serves to exercise the eyes of persons exposed thereto. The average luminosity, and the amplitude and period of modulation can be set and adjusted by the user. The rate of modulation is sufficiently slow that the level of change of luminosity is accommodated by human eyes and is imperceptible through the eyes of persons exposed thereto. In one embodiment, an illuminance sensor is provided to read the actual illumination of a lighted object. The values of the illumination so read are fed back in the device to adjust the luminosity of the lighting facility, so that the object is illuminated in the desired cyclical manner.

  • Patent number: 5228306
    Abstract: An apparatus for controlling air-exchange and pressure conditions in an air-conditioned room by opening and closing ducts and operating fans. The apparatus provides required indoor air pressure, such as a positive pressure for preventing dust from entering a room, or a cyclically modulated pressure in specific modes for achieving special atmospheric effects, such as to improve the spirits of occupants or to expel insects. The rate of change of the indoor pressure relative to the outdoor pressure can be measured in order to detect the degree of airtightness of the room. A warning signal is triggered when an abnormal condition of airtightness occurs, so that users may take steps to minimize unnecessary air-exchange, reduce energy consumption, and increase efficiency for air filtering and air conditioning.
