Latest Patents

One of Havens' latest patents is the Peer Relationship Transceiver. This transceiver is designed for communication with another transceiver over a common channel, utilizing a technique that allows both devices to be identical in manufacture and use. This approach eliminates the need to designate one transceiver as the 'master' and the other as the 'slave', relying instead on random time differences during a start-up period to establish communication. The transmissions typically occur in multi-bit packets, with an example involving an optical transceiver that uses a light-emitting diode for both transmission and detection over an optical fiber channel.

Another significant patent is the Low Resistance Origination Scan Circuit. This circuit is engineered to detect the circuit closure state in a loop circuit with much lower impedance than typical designs. It splits the source impedance into separate resistive parts that connect the opposite terminals of an office battery to the tip and ring leads of the loop. The circuit senses and sums currents in these resistive parts to compare against a threshold current, indicating whether a subscriber station is off-hook. The threshold current can be adjusted for different applications, and when an off-hook state is detected, the circuit disables itself to allow loop current to be provided by other means.
