Audible Signals (e.g., Bell Rings Softly First And Then Loudly) Patents (Class 340/328)
  • Patent number: 4785280
    Abstract: The system includes a plurality of sensor devices each arranged to monitor a respective physical or operating magnitude of apparatus, a device or a member of the vehicle, and to provide corresponding electrical signals. An acoustic signal generator provides a plurality of acoustic characterizing signals, indicative of corresponding predetermined operating conditions, and a plurality of acoustic level signals indicative of corresponding predetermined levels of importance attributable to the operating conditions. A processing unit detects on the basis of signals provided by the sensor devices the operating conditions of the vehicle and attaches in a predetermined manner, a level of importance to each operating condition identified, and supplies to the acoustic signal generator electrical control signals for causing the output of an acoustic signal comprising, in succession, the level signal and the characterizing signal associated with the operating condition detected.

  • Patent number: 4765548
    Abstract: Garbage disposal apparatus of the type used in fast food restaurants for receiving refuse from food trays has a garbage-receiving cabinet with a vertically slidable door panel operated by a pedal-actuated mechanism, permitting two-handed handling of the food trays. The door panel is retracted by pedal action, leaving an unobstructed access opening available for assured, non-spilling sanitary dumping, as long as the pedal is depressed. The mechanism is supported protectedly and visibly in the space provided between two parallel vertical panels which together form the receiving cabinet front, the foremost of the two panels being transparent. Also positioned in the space between the two front panels is a sound-generating system, activated by the movement of either the door panel or the mechanism moving it.

  • Patent number: 4544920
    Abstract: Apparatus and method are provided for protecting an unoccupied building. The apparatus includes a noise detector for detecting noises generated by attempts to enter the building. Any noise detected is converted to an electronic signal and conveyed to an activator. The activator turns on a tape player which plays a tape recording of noise such as a barking dog. The noise is played through speakers within the building to give the impression the building is occupied or guarded by a watchdog.

  • Patent number: 4426639
    Abstract: A timing apparatus for holding a door open for a controlled period of time before releasing it for closure. The timing apparatus includes a switch operable to produce a switching signal. A first energizing control is coupled to the switch and is responsive to the switching signal for producing a first signal. An electromagnetic device is coupled to the first energizing control and is energizable in response to the first signal. A first timing circuit is coupled to the first energizing control and is responsive to the first signal to generate a first timing signal of predetermined duration and corresponding to the switching signal. The first energizing control is further responsive to the first timing signal thereby to remain in the state of providing the first signal for such predetermined duration. A second timing circuit is coupled to the first timing circuit and is responsive to the termination of the first timing signal to produce a second timing signal of second predetermined duration.

  • Patent number: 4323883
    Abstract: A doorbell for pets consisting of a pair of scratch plates adapted to be hung movably respectively on the inner and outer surfaces of a door of a house or other building for yieldable movement toward said door under the impetus of a pet's scratching thereagainst, and an electrical system including an audible signalling device operable by switches mounted in the door and actuated by said scratch plates. Provision is made for maintaining operation of the signalling devices for any desired length of time despite merely momentary movements of the scratch plates, and for adjusting the force required to actuate the signals, both to prevent accidental operation by blowing wind, and to accommodate the device to pets of different sizes and strengths. The signals may be audibly distinguishable, to indicate whether the animal desires ingress or egress.

  • Patent number: 4224613
    Abstract: A warning system for a printing press to warn the operator upon the exceeding, or departure from, a desired set of running conditions which includes a plurality of remote condition transducers which, in the simplest form of the invention, are in the form of switches. Coupled to the transducers are respective signal generators each of which generates an acoustic signal which has a distinctive quality as compared to all of the other acoustic signals. A loudspeaker common to all of the signal generators is audible at the control station. The distinctiveness of the signal serves to promptly inform the operator which of the running conditions has been exceeded so that corrective action may be taken. In a second embodiment of the invention the transducers produce output control signals which vary in magnitude with the condition, and the corresponding acoustic signal generator produces a signal having a distinctive first quality when the control signal exceeds a threshold level.

  • Patent number: 4219799
    Abstract: My invention teaches a vehicular signal apparatus, in particular a motor vehicle horn system, which has two successive loudness levels of operation. The first loudness level is a moderate level used as a brief "toot" to give a quick alert, as in pedestrian traffic or the like. The second loudness level is a commanding level used as a blast, as for example, in an emergency maneuver in heavy traffic. Operation is automatic, in the sense that a brief operator activation of the horn signal switch will result only in the activation of the moderate level horn, whereas operation of the blast horn is delayed such that continuous operator activation of the horn signal switch will cause the blast horn to blow within about a second after horn switch contact is made.
