Abstract: An SCSI bus line apparatus including in combination at least two of any of an active deassertion (ADR) circuit, a signal line impedance matching (SLIM) circuit and a signal line increased circuit kicker (SLICK) circuit. In the ADR circuit, if a current sinking circuit senses an increased voltage on the common node of the signal lines of a bus due to active deassertion of a signal line, the current sinking circuit sinks enough current from the signal lines to prevent an over-current condition on asserted signal lines or soon-to-be asserted signal lines. In the SLIM circuit, transient voltages are removed from a signal line by limiting to within a range the voltages that can appear on the signal line.

Abstract: The charge shared precharge circuit of the present invention is coupled to the match line. The precharge circuit is disposed between the match line and a match line, and includes a CMOS passgate having an N channel and a P channel gate. An inverter acts as a match driver and is coupled between the match and match lines at the CMOS passgate's input and output. The input to the N channel gate of the pass gate is coupled through an inverter to the input of the P channel gate. The N channel gate is further coupled to V.sub.cc through two serially coupled P channel transistors receive BEQ line and an SAE signal, respectively. At the beginning of a compare cycle, BEQ is driven low as is SAE, thereby turning on the serially coupled P channel transistors and coupling V.sub.cc to the input of the N channel gate of the passgate. The P channel gate of the passgate is also opened due to the placement of the inverter between the N and P channel gates.

Abstract: A deflection waveform correction signal generator comprises a multiplying circuit for generating a pincushion correction signal. A horizontal frequency ramp is generated by a clipped retrace pulse. The ramp generator has an output coupled to an integrating circuit for generating a parabolic shaped signal. The ramp generator and ramp integrator are reset at a horizontal rate by reset pulses of differing duration. The different duration of reset pulses results in the parabolic signal having regions of non-parabolic shape. The parabolic shaped signal is coupled to an input of the multiplying circuit. A control circuit is coupled to the parabolic shaped signal for maintaining a peak amplitude thereof by controllable coupling to the ramp generator. A control loop is coupled to the integrator for controlling an integrator input bias current to generate the parabolic shaped signal at a predetermined time interval.

Abstract: This circuit facilitates the triggerability of a remote three wire flashtube and trigger coil assembly at a much lower than normal anode power supply voltage. The discharge of the trigger capacitor produces the usual trigger-event in the trigger coil. Simultaneously, a trigger boost capacitor boosts the flashtube anode voltage to approximate the supply voltage plus the voltage across the trigger coil primary winding. As a result, the flashtube anode voltage is essentially doubled at the outset of each trigger event.

Abstract: Accurate detection of an existing link (current road location between two road nodes) of a vehicle by an on-board navigation system. Upon each periodic detection of the position, azimuth and velocity of the vehicle by a GPS receiver, all the links within a predetermined distance of the vehicle position are extracted by looking up road data read out from a CD-ROM. For each of the links, the distance from the vehicle position, the angle with the vehicle azimuth, the angle between the vehicle azimuth and a passable direction of the link, the difference between the vehicle velocity and the speed limit for the link and the connectability with the last-detected existing link are obtained and are substituted into a predetermined existential probability evaluation function to calculate an existential probability. The link with the largest existential probability is determined to be the existing link.
