  • Patent number: 5967536
    Abstract: A system and method is disclosed for converting stock MacPherson strut suspension systems for a host automobile to a double A-arm type of suspension system using only stock or pre-existing mounting locations and only ordinary hand tools. The system and method uses a lower A-arm that mounts in the stock mounting locations of the frame that held the stock lower control arm of the original MacPherson strut suspension system. A upper A-arm conversion bracket mounts to stock fastener locations on the main frame, and is configured to securely hold the replacement upper A-arm. A replacement spindle is mounted between the upper and lower A-arms, and holds the stock hub and brake assemblies. The original steering arm is coupled to the replacement spindle, and the original sway bar is coupled to the replacement lower A-arm. A coil-over shock is mounted to the lower control arm and the conversion bracket. The kit bolts in place on the host vehicle without any modification to the original frame or body work.

  • Patent number: 4641266
    Abstract: In a processing system (10) that utilizes daisy-chain arbitration for controlling access to a shared resource (11,13) by a plurality of using devices (1-4,12), a using device (1-4) is allowed to issue an access request signal onto a request signal line (17) shared in common with the other using devices (1-4) only when it senses that the request line is idle. Sensing is done during one clock period and issuance of the request signal is done during the next clock period. The clock period exceeds the signal propagation delay across the request line. Receipt by the arbitrator (14) of a request signal is delayed by a clock period. Access grant signals are daisy-chained by a grant line (18) between the using devices (1-4), without synchronization at each device of issuance of the request signal and receipt of the grant signal, and without multiple sampling at each device of the grant signal.
