Latest Patents

Carr's latest patents include the Packet Bus Interface and the Mini Packet Receiver Transmitter (MPRT). The Packet Bus Interface, also known as the Arbitrated Bus Interface (ABI), consists of a set of custom LSI circuits that facilitate the sending and receiving of minipackets of binary information to and from a data bus. This innovative interface performs essential functions such as arbitration, address recognition, and buffering, which are crucial for the effective transmission and reception of mini-packets between the local packet bus and a microprocessor.

The MPRT provides an interface between one or two eight-bit microprocessors and a digital subscriber loop interface circuit. It enables bi-directional communication over a single wire pair by alternating the subscriber loop's receive and transmit frames, controlled by a 'Ping-Pong Protocol'. This protocol utilizes a fixed frame format and bipolar alternate mark inversion (AMI) line encoding. The MPRT features two microprocessor ports: a transparent port for voice transmission and a non-transparent port for data transmission. It implements the Mini Packet Protocol frame format as a mini packet (MP) of information for both types of data.
