  • Patent number: 10634022
    Abstract: A system and method for determining a condition of a filter filtering fuel associated with an engine. Input information relating to the operation of the engine is provided by a plurality of sensors. At least some of the input information is used to determine a plurality of input variables, the plurality of input variables representing a plurality of engine operating conditions including engine run time, engine torque and engine speed. An algorithm incorporating the input variables is used to determine the condition of the filter. Information concerning the condition of the filter may be output to a user such as an operator or service provider.
    Type: Grant

  • Patent number: 5122686
    Abstract: A low voltage current mirror termination circuit used with an ECL gate array for providing a constant output emitter follower reference current (Ief) which is independent of voltage variations in a separate output emitter follower power supply source (VEF) includes a lateral PNP transistor (Qp), an NPN mirror transistor (Qx), at least one pull-down transistor (Qf), and at least one NPN output emitter follower transistor (Qo). The current through the collector of the lateral PNP transistor (Qp) defines a mirror current (Ip). The base of the lateral transistor (Qp) is connected to receive a base bias voltage VEP. The current through the collector of the pull-down transistor (Qf) defines the constant output emitter follower reference current (Ief) which is proportional to the mirror current (Ip). The separate emitter follower power supply source (VEF) has a voltage which is lower than a supply source (VEE) so as to reduce significantly the power consumption.

  • Patent number: 4138739
    Abstract: High emitter-coupled logic switching speeds and low standby power are achieved with a dual-port RAM cell in which two NPN Schottky transistors in a non-saturable bistable flip-flop configuration are flanked by a second pair of transistors whose collectors are individually coupled to the flip-flop collectors. The two output digit lines of the RAM are individually connected to the emitters of the flanking transistors, and their bases are individually coupled to the two select lines. A read signal on either select line enables a flanking transistor to sense the state of the RAM. Writing is accomplished by applying a high logic signal to both select lines and one digit line while the other digit line is dropped to a low state.

  • Patent number: 4041326
    Abstract: A very high-speed exclusive OR/NOR circuit in which output function and its complement are propagated simultaneously. Developed particularly for use in integrated circuit applications, the basis circuit uses six NPN transistors in a tree configuration to select one of four mutually exclusive conductive paths which correspond to the four states of the truth table of a two-variable exclusive OR/NOR function.
