Abstract: A system for identifying irregularities in behaviors of a non-human animal, the system comprising a processing circuitry configured to: provide a behavioral baseline including first information on regular behaviors of the non-human animal over a given period of time when no irregularities occur; obtain data on a series of consecutively identified behaviors of the non-human animal identified over a second period of time; perform an action upon the data not complying with the behavioral baseline, thereby indicating an irregularity in the non-human animal behavior.

Abstract: The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.

Abstract: A fluid-operated regulating apparatus for use in a motor vehicle, particularly to control the operation of a consumer, such as a clutch which transmits torque between an engine and a transmission in the power train of a vehicle as a function of one or more parameters, comprises at least one pump which supplies a flow of pressurized hydraulic or pneumatic fluid to the consumer by way of a valve controlled by an electronic unit which receives signals from a plurality of sensors. The signals which the electronic unit transmits to the valve are dependent upon at least one variable parameter which is generated by a plurality of components. One of these components is modulated or modulatable at a first frequency, and another of these components is modulated or modulatable at a second frequency which can be higher or lower than the first frequency.

Abstract: A process for regulating continuously variable transmissions in motor vehicles by means of a controller includes a first control circuit as a speed controller for regulating the transmission input speed as the product calculated from the transmission output speed and the transmission ratio, and a second control circuit post-connected to the first control circuit as a speed gradient controller for regulating the time derivative of the transmission input speed. A correction value, dependent on the functional value of a correcting function and obtained from a correction element, is added to the summation element at the controller input of one of the two control circuits. The correction value is obtained such that the regulating ranges are specified, respectively, with a different control behavior of the controller.
