Title: A method for monitoring the friction between the roadway and the tyres of driven motor vehicle wheels
Inventor: WEBER RODIGER
IPC: B60T8/1761
Filed: 1991-04-02
Abstract: In order to inform the driver of a motor vehicle during normal vehicle operation in good time about the state of the roadway, that is about the friction a connection between the roadway and the tyres of the driven wheels, the wheel slip ( lambda ) and the simultaneously effective wheel peripheral force (K) of the monitored driven wheels are ascertained in continuous sequence during steady operation conditions when the vehicle is not being braked or accelerated, wherein the wheel slip is ascertained with an accuracy which is in the <o>/<oo> range. The wheel peripheral force/wheel slip value pairs ascertained for a substantially dry roadway ( mu n) are stored and the subsequent occurrence or detection of such a value pair, whose wheel slip ( lambda "m1) is noticeably greater than that ( lambda m1) of a previously stored value pair having the same wheel periphery force (K1) indicates a reduction in friction. A warning signal may be given or a control action initiated. Various means for measuring wheel slip and peripheral force are disclosed. <IMAGE>

Title: Maximum likelihood sequence metric calculator.
Inventor: YAMASAKI RICHARD G
IPC: H04L25/03
Filed: 1992-02-25
Abstract: A maximum likelihood sequence metric calculator for use in a sequence decoder for processing sequences of sampled values from a communication channel or recording device. The metric calculator 76, 80 can be used in a maximum likelihood decoder, where the sequence can be based upon a 2-state trellis. This would include duobinary, dicode, or partial response class IV signalling. The survivor metrics for the two states is proportional to the peak amplitude detected for that state. Thus, the peak amplitude for a state is stored by a peak detector, until an opposite polarity amplitude is detected to switch the trellis path to the opposite polarity state. The path switching threshold to a state is determined by the opposite polarity state's peak amplitude and the maximum likelihood threshold value. Since only the peak amplitude of the state is stored, unbounded metric absolute value growth is not a problem. <IMAGE>

Title: Current limit circuit for driving a MOSFET or IGBT
Inventor: PARRY JOHN
IPC: H03G3/30
Filed: 1992-11-26
Abstract: A method for controlling the current through a MOSFET or IGBT is described. An amplifier having a single, high-frequency pole is used to drive the large gate capacitance of a power MOSFET or IGBT. The current in the power transistor generates a negative feedback voltage in a sensing resistor 108. This feedback voltage is compared with a reference voltage to determine the output voltage of the amplifier. This provides greater stability for driving MOSFET or IGBT transistors, and the actual frequency response is only dependent upon the poles generated by the power transistor and its load. The current in the transistor ramps up to a value determined by the reference voltage, and then settles to a constant value with little or no overshoot or oscillation. <IMAGE>

Title: Cryptography system.
Inventor: MERRICK ROLAND ALBERT
IPC: H04L9/08
Filed: 1992-12-19
Abstract: A cryptographic system includes a conventional DES facility 12 for encrypting data using a key of N (=56) bits. The user 100 however need only supply a first key 30 of n bits, which is passed to a key management system 20. The key management system generates a second key of length N-n bits, which is combined with the first key to produce a full-length key 40 of N bits. This full-length key is then passed to the DES facility to allow data 16 to be encrypted and saved in a data store 14 in the conventional manner. The value of n can he controlled such that if the user forgets the first key, it can be located in a reasonable time on a simple trial and error basis, thereby allowing retrieval of the encrypted data. <IMAGE>

Title: Low voltage detection circuit for use in a remote control unit
Inventor: SIMMONS JR CARLTON JETHRO
IPC: G01R31/36
Filed: 1994-03-01
Abstract: A battery monitoring apparatus 110 in a remote control unit measures the time it takes for a charging circuit C160 connected to the battery +V, to charge to a predetermined level. A weak battery takes a longer time to charge than does a fully charged battery. The charging time associated with a fully charged battery is measured by a timer 119 and recorded in a RAM 116 and compared to subsequent charging time measurements. When the difference between the recorded charging time and a currently-measured charging time exceeds a predetermined value, a weak-battery alert signal is generated. In one embodiment, the alert signal is applied to a visible LED driver circuit 170; in another embodiment, the weak=battery alert signal is transmitted to the controlled equipment which alerts the user. <IMAGE>
