Arrangement for a cruise control system for a motor vehicle

Abstract: Control unit (1) for a cruise control system for a motor vehicle including at least one manually operated movable switch (4) for operating the cruise control system. The switch (4) has a neutral position (6) and can, when moved away from the neutral position (6) in a first direction, assume a first position (8) in which the switch (4) gives a control unit (21) a signal for temporarily switching off the system without cancellation of set speed. The switch (4) can also, when moved away from the neutral position (6) in the first direction, assume a second position (10) in which the switch (4) conveys signals to the control unit (21) in order to facilitate for the cruise control system to access, in some predetermined manner, a set speed stored in a memory unit situated in the control unit (21), where the second position (10) can only be reached by the switch (4) passing through the first position (8).

Model for simulation of IR countermeasure effect on IR-seeker/missile

Abstract: TACSI (TACtical SImulation) is an existing simulator used as a tactical environment for manned simulators at Saab Aerosystems. TACSI can also be used as a stand-alone desktop development and simulation tool. TACSI simulates a large number of entities and functions such as platforms, sensors, weapons, signatures, communication, multisensor fusion, decision support etc. TACSI has a rule based pilot model and uses High Level Architecture (HLA) for interfacing with other simulation models. This model, a development of TACSI, simulates the flight dynamics, IR-signature and IR-seeker operation. The dynamic behaviour of the aircraft, the IRCM, the missile and the IR-seeker are modelled. The IR-contrast seen by the seeker through the atmosphere in front of the aircraft and the IRCM are spectrally and dynamically modelled. The seeker operation behaviour and function are also modelled. To implement this in a real-time simulation system simplifications are necessary. This paper describes the simplifications to model the IR-contrast and the seeker function. This model is used to analyse the effect of IR countermeasures (IRCM) on a missile IR-seeker.

A compact 1 to 18 GHz planar spiral antenna for interferometer and other direction finding applications

Abstract: This paper discusses the development of a compact light-weight planar spiral antenna for use in amplitude comparison and interferometer direction finding (DF) applications covering 1 to 18 GHz. The antenna uses a slow-wave (zigzag) spiral radiator which results in a cavity diameter which is only 68% of the wavelength at 1 GHz. The two-arm spiral is fed by a Marchand balun and achieves a VSWR of less than 1.5∶1 over almost the entire 1 to 18 GHz frequency range. The spiral antennas are supplied in phase and amplitude tracking sets for wideband DF applications. Amplitude and phase tracking performance for a fully integrated linear interferometer DF panel which includes the radome and feed cable effects are presented. Phase DF performance for the panel with pulse receivers as measured in an anechoic chamber is discussed.

Device for winding and unwinding a wire.

Abstract: A device for winding and unwinding a wire, such as a relatively thin electric cable is described. It comprises a winding element (1) suitably in the form of a drum and a wire guidance means (4) which is rotatable relative to the winding element (1) and axially movable in relation to same. The device is characterized particularly in that the circumference of the winding element (1), speed of rotation and axial speed are so adjusted mutually and to the diameter of the wire that the wire on winding is wound up on the winding element (1) by means of the wire guidance means (4), rotation by rotation repetitively, from the surface of the winding element (1) up to a maximum radial extension.

Battery unit for e.g. hybrid-driven motor vehicle, has battery cells lying on ramp and with boundary walls, where adjacent cells are oriented in such a way that cells overlap partially in inclined position on support in squamous manner

Abstract: Unit has battery cells (12) lying on a fixed deflecting ramp (40) and including main boundary walls (24, 26). The cells are connected with one another and the walls of adjacent cells are evenly supported on top of one another. The adjacent cells lie on a support and are oriented in such a way that the cells with the walls overlap partially in an inclined position on the support in a squamous manner. An independent claim is also included for a motor-driven vehicle with a battery unit.
