Abstract: In a signal processing channel, digital values, corresponding to a digitized incoming analog signal representative of coded binary data, are processed. Using a state-dependent sequence detection algorithm appropriate functional expressions of digital sample values are precomputed at each cycle of the digitizing clock for a preselected number of bits ahead of the current bit. Preselected ones of these expressions are compared against corresponding thresholds to provide respective binary decision outputs that, with state values corresponding to the current state, determine state values for the next state and decode one bit of coded binary data at each clock cycle. Programmed values generated for the thresholds may be adaptively modified according to changes in sample values in the incoming analog signal relative to corresponding expected sample values. Different thresholds are used for positive and negative phases of the analog signal shape to accommodate signal shape asymmetry. Because the decoder is programmable, threshold constants at different tracks or bands of tracks in a disk file can be changed to optimize performance at all tracks of the file.

Abstract: A microprocessor-controlled pH and ion concentration meter is disclosed with improved calibration and testing procedures. For calibration (standardization), the meter stores number pairs (pX a , E a ), (pX b , E b ) where the pX values may be pH values (e.g., 4.00 and 7.00) and the E values are expressed in mV/deg K. When multiple standard values are stored, remeasuring one (e.g., replacing E a1  by E a2 ) can be used to update the others (e.g., E b1  to E b2 ) without remeasurement by applying the formula: 
E b2  = E b1  + (E a2  - E a1 ). 
The meter can be tested for excessive internal bias current by measuring the potential (V1) when the meter is connected to a circuit a known voltage (E1) of low impedance and the potential (V2) when the meter is connected to a circuit of the same voltage source (E1) but of known high impedance and having the meter compare (V2 - V1) to a preset limit value. The meter can be tested for low internal impedance by further measuring the potential (V4) when the meter is connected to a circuit of a second external voltage (E2) and the known high impedance (R1). The meter then calculates: 
(V4 - V2) 
and compares that value to preset limits based upon E1, E2 and R1. Such limits can be derived as (Z₀)(E2-E1) / (R₁ + Z₀) wherein Z₀ is the minimum acceptable internal impedance.

Abstract: A drive circuit for a voltage driven type semiconductor device (Q1) having a serial circuit of a resistor (R5) and a Zener diode (ZD1). One terminal of the serial circuit is connected to an output terminal (collector) of the semiconductor device (Q1). An overcurrent flowing in the semiconductor device is detected based on a current flowing through the serial circuit and the presence or absence of a drive signal (V DR ) fed to the drive circuit from an external control circuit. The detection level (V th1 ) of the overcurrent can be adjusted by the voltage of the Zener diode (ZD1), and the quick detection becomes possible. This arrangement makes it possible to detect an overcurrent in the semiconductor device, and hence to detect a shortcircuit in a circuit connected to that device in a minimal time required, thereby reducing the energy consumed in the semiconductor device during the short circuit.

Abstract: An on-vehicle navigation apparatus has enhanced efficiency of the use of a memory for storing the locus data, without losing the details and accuracy of a locus pattern drawn on the basis of collected locus data. The on-vehicle navigation apparatus acquires vehicle location information C and time information T, and stores the vehicle location information C as locus data Si and the associated time information T as collecting time data Ti in response to a collection command. The apparatus then computes a travel distance D from the previous locus data collecting position on the basis of the vehicle location information C and the locus data Si, computes elapsed time ΔT from the previous locus data collecting time on the basis of the time information T and the collecting time data Ti, and generates the collection command when the elapsed time ΔT reaches a predetermined time after a predetermined travel distance D is reached.
