20150303805 | AN INDUCTIVE LOAD CONTROL CIRCUIT, A BRAKING SYSTEM FOR A VEHICLE AND A METHOD OF MEASURING CURRENT IN AN INDUCTIVE LOAD CONTROL CIRCUIT - A method and circuit for controlling current through an inductive load such as an electromagnetic valve of a vehicle anti-lock braking system includes first and second driver stages, controlled by PWM (pulse width modulation) signals, for providing, respectively, an actuation path for valve current in an “on” phase and a recirculation path for valve current in an “off” phase. A peak value of current flowing in the actuation path at the end of an “on” phase is compared with a peak value of current flowing in the recirculation path at the start of the “off” phase in order to detect any malfunction of the circuit. An embodiment of the invention has the advantage of being able to detect any malfunction at very low and very high PWM duty cycles. | 10-22-2015 |
20150336556 | A HOMOGENEITY DETECTION CIRCUIT, A VALVE DRIVING SYSTEM AND A METHOD OF HOMOGENEITY DETECTION IN A VALVE DRIVING SYSTEM - A homogeneity detection circuit, a valve driving system, a vehicle, an integrated circuit and a method of homogeneity detection in a valve driving system are provided.

The first input receives a first signal being related to a first driving signal for driving a first valve. The second input receives a second signal being related to a second driving signal for driving a second valve. The comparison circuit compares the first signal with the second signal and generates a warning signal if predetermined differences are detected between the first driving signal and the second driving signal. | 11-26-2015 |
20150341029 | SEMICONDUCTOR DEVICE AND POWER CIRCUIT INCLUDING A SENSE TRANSISTOR FOR CURRENT SENSING - A semiconductor device comprises a power transistor and a sense transistor. The power transistor conducts a power transistor current. The sense transistor conducts a sense transistor current substantially proportional to of the power transistor current. The power transistor and the sense transistor have drain source and a gate terminals, of which those of the sense transistor are arranged to be biased to those of the power transistor, respectively. The power transistor and the sense transistor each comprise: an inner region of type P−; an N-type buried layer; an N-type isolating barrier surrounding the inner region partially; an N-type source region in the inner region; an N-type drain region in the inner region. A barrier-to-drain connector connects the isolating barrier to the drain region, the one of the sense transistor has an electrical resistance which is higher than the resistance of the barrier-to-drain connector of the power transistor. | 11-26-2015 |

The control units comprise an electronic micro controller which in response to the operation of said push-button causes the visualization of the duration and the frequency of the selected program, and in response to a single operation of the start push-button causes the immediate start of the selected watering program, while the operation of the start push-button for a variable number of times programs the delayed start of the selected program. | 08-15-2013 |
20130211604 | ELECTRONIC CONTROL UNIT WITH ONE OR TWO WAYS CONTROLLED BY ELECTROVALVES FOR PROGRAMMED WATERING OF LAWNS, GARDENS, FLOWER BOXES AND SIMILAR SPACES - An electronic control unit for programmed watering of lawns, gardens, flower boxes and similar spaces, comprises a front panel, a display, watering program selection push-buttons for selecting the watering duration and the watering repetition frequency and at least one start push-button for starting the selected program. The control unit comprises an electronic micro controller which, in response to the operation of said selection push-buttons, controls the visualization of the duration and frequency of the selected program and, in response to a single operation of the start push-button, controls the immediate start of the selected watering program. If the start push-button is operated for a variable number of times, the micro controller programs the delayed start of the selected program. | 08-15-2013 |
20150216133 | VALVE BOX WITH ELECTROVALVES FOR REMOTELY CONTROLLED IRRIGATION SYSTEMS - A valve box for irrigation systems is described, comprising a box-shaped body closed by a lid, and a plurality of electro-valves contained in an inner compartment of said box-shaped body and adapted to allow a fluid from a supply conduit to flow towards a plurality of outlet conduits, each being controlled by an electrovalve. The valve box comprises a single programmable drive and control module of said electrovalves which is contained in a containment box releasably secured above said compartment. | 08-06-2015 |
20150217321 | DISPENSING HEAD WITH A NEW FLOW ADJUSTMENT UNIT FOR A POP-UP UNDERGROUND SPRINKLER - An underground sprinkler of the pop-up type, comprising a main tubular outer body, intended to be vertically buried underground, and an inner body or moving piston slidably inserted into said main body, includes a water dispensing head provided with a diffusing unit at the top of said inner body or piston. The above-mentioned moving piston is typically elastically held in a resting position with its head lowered, and it is displaceable to the irrigation position with its head lifted by a pressure of the water supplied to the base of the main body. The dispensing head comprises a jet adjusting unit arranged in such a position as to be manually accessible from the outside when said head is lifted to the irrigation position. | 08-06-2015 |
