Abstract
A signalling device for use in a public transportation vehicle. The signalling device includes a cord, or other device by which a passenger on the vehicle can signal the driver, and a device for generating a signal, normally a buzzer. A control circuit senses the actuation of the passenger's device and controls the energization of the signal generating device. The pattern of the signals may take any of several forms.
Claims6
A controller for use in signalling system that includes actuation means activated by one person desiring to signal a second person, electrically operated signal means for generating a warning signal to the second person and a power supply, said controller comprising:
- A. sensing means for sensing the activation of the actuation means by the one person,
- B. pattern generating control means connected to said sensing means for generating a self-completing predetermined control function defining a pattern of energization and deenergization for the warning signal, said pattern generating means being solely responsive to said sensing means sensing activation of the actuation means and being self-setting, and
- C. switching means for connection in circuit with the power supply and the signal means, said switching means being connected to said pattern generating control means for controlling the energization of the signal means solely in response to the predetermined control function generated by said pattern generating control means.
