Abstract: A door lock includes a latch bolt and an auxiliary bolt. A stop member is supported by the auxiliary bolt and is movable relative to the auxiliary bolt between a position in which it prevents a guide element moving to a position providing deadlocking of the latch bolt, while the auxiliary bolt is in a protruding position, and a position in which it allows the guide element to move to a position providing the deadlocking of the latch bolt. The stop member allows the guide element to move to the position providing deadlocking of the latch bolt only in case both the auxiliary bolt and the latch bolt are first moved to retracted positions.

Abstract: A switching converter produces an output signal transmitted to a variable load impedance to produce a load voltage VDD across the load impedance and holds VDD close to a set point voltage VSP selected by control data DREF1 to compensate for variations in the load impedance which tend to drive VDD away from VSP. The switching converter includes a pulse-width modulated power converter for producing the output signal of voltage VOUT in response to an input signal of voltage VIN, wherein a ratio VOUT/VIN is a function of a duty cycle D1 of a pulse-width modulated signal VPWM1. A pulse-width modulation circuit generates the VPWM signal of duty cycle D1 controlled by a control signal, and a feedback control circuit monitoring the load voltage VDD adjusts D1 to keep the load voltage as close as possible to VSP. A power source supplies the input signal of voltage VIN to the power converter.

Abstract: An an internal combustion engine has a plurality of cylinders for providing the necessary energy used for the work performed by the engine. Cylinder specific knock monitoring is used in order to distribute the load automatically among the cylinders of the engine. When an individual cylinder knocks continuously, the antiknock control system of the cylinder aims at reducing permanently the quantity of fuel supplied to the cylinder. The fall in the total output caused by the reduction of fuel supply is compensated by increasing the fuel supply to all cylinders. The new operating values of the engine provided by the adjustment are stored in the memory and used also as new reference values.

Abstract: An electronic device under test (DUT) responds to a digital input signal by generating a digital DUT output signal conveying a repetitive digital signal pattern. An apparatus for measuring various characteristics of the DUT output signal includes a trigger generator for generating a series of trigger signal edges in response to selected DUT output signal edges occurring during separate repetitions of the digital signal pattern. The trigger generator can be configured to generate each trigger signal edge in response to the same or a different edge of the digital signal pattern. The apparatus determines when a DUT output signal edge occurs by determining when the DUT output signal rises above or falls below adjustable reference voltages. The apparatus alternatively responds to each trigger signal edge by measuring a period between two different edges of the digital signal pattern and or by repetitively sampling the DUT output signal to determine its state.

Abstract: A triggering circuit asserts a trigger signal in response to edges of a digital signal conveying a repetitive pattern of edges. The triggering circuit generates first data having a value identifying a position within the pattern of a last occurring edge of the digital signal and generates second data having a value identifying a position of a particular edge within the pattern that is to initiate a next assertion of the trigger signal. The triggering circuit asserts the trigger signal when the first and second data values match and de-asserts the trigger signal when the first and second data do not match. In a repetitive mode of operation, the triggering circuit keeps the second data value constant so that it always asserts the trigger signal in response to the same edge of the pattern.

Abstract: A schematic diagram generator processes a netlist to generate a schematic diagram based on a set of placement rules, corresponding to a separate characteristic pattern of interconnected devices and specifying a constraint on relative placement within the schematic diagram of symbols representing devices forming the pattern. The generator identifies each set of devices in the netlist that exhibits any rule's interconnection pattern as a separate “soft group”, places a constraint consistent with the rule on relative positioning within the schematic diagram of symbols representing the soft group, resolves any constraint conflicts in accordance with a constraint resolution scheme, and then places all device symbols in the schematic diagram in a manner consistent accordance with the constraints.

Abstract: A method is disclosed for operating an internal combustion engine of the type having an engine cylinder with a reciprocating piston, first and second intake ports for admitting gas from an ambient air supply into the engine cylinder, first and second intake valves each arranged between a respective one of the intake ports and the engine cylinder, a non-return valve arranged in the second of the intake ports at a distance from the second intake valve and oriented to allow gas to flow only towards the engine cylinder, and a variable valve actuating system for controlling the opening and closing of at least the second intake valve. In the method of the invention, in at least one operating mode of the engine, the second intake valve is opened and closed, while the cylinder is fully isolated from the ambient air, to permit gas transfer between the cylinder and an auxiliary chamber temporarily defined by the part of the second intake port lying between the second intake valve and the non-return valve.

Abstract: A co-verification system includes a computer programmed to act as a simulator for simulating behavior of a first portion of an electronic device under test (DUT) by acquiring, processing and generating data representing DUT signals. The co-verification system also includes emulation resources programmed to emulate a second portion of the DUT by receiving, processing and generating emulation signals representing DUT signals. The signals of the DUT are mapped to separate addresses within a memory space, and the simulator controls and reads states of emulation signals by writing data to and reading data from addresses of the memory space states mapped to the DUT signals the emulation signals represent. The computer and the emulation resources are also programmed to implement transactors communicating with one another through a packet routing network. The transactors set states of the emulation signals when the simulator writes to memory space addresses and for reading states of the emulation signals.
