  • Electronic control system for operating a street lamp
    Patent number: 8872433
    Abstract: An electronic control system for operating lighting is rated and operable from normal AC mains supply voltages. A street light controller is adapted to activate a luminaire when ambient light levels are considered too dark and, conversely, when ambient light levels are sufficient, the luminaire is turned off.
    Type: Grant
    Filed: March 20, 2013
    Date of Patent: October 28, 2014
    Assignee: Hendon Semiconductors Pty. Ltd.

  • Bi-directional bus buffer
    Patent number: 7348803
    Abstract: A bi-directional bus buffer for applications using the I2C and SMBus, or other bus systems operating on similar principles, able to extend the bus load limit by buffering both the SCL and SDA (clock and data) lines, allowing capacitive loads of up to the limit of 400 pF on both sides of the buffer. With the use of an enable function, sections of the bus can be isolated, and then, thorough the use of a number of these buffers, different parts of the system are able to be isolated, and brought on-line successively or in a controlled manner, permitting a controlled start-up, and operation at maximum performance speeds while still having a diverse range of components, operating speeds and loads.
