Abstract: A field frame processor in a digital image system capable of preventing a blazing fire of a screen when decoding data which is encoded by an encoder is disclosed. In the processor, an odd and even field separator(11) separates odd and even fields from an image input when an encoder in a digital image system selectively processes a field/frame. Odd and even movement estimators(13,14) estimate movements of the odd and even fields from the odd and even field separator(11). A calculating section(15) calculates a difference of absolute values of outputs from the odd and even movement estimators(13,14). A threshold value section(16) provides a threshold value output to control a driving of a field separator(17) based on the output of the calculating section(15).

Title: Electrical apparatus with an autonomous energy source for sampling powders from industrial spaces prone to forming an explosive atmosphere
Inventor: SIMION SPIRIDON
IPC: B01D46/02
Filed: 2003-04-08
Abstract: The invention relates to an electrical apparatus with an autonomous energy source meant to sample powders from rooms prone to forming an explosive atmosphere, for carrying out the periodic control of the dusting level in order to evaluate the risk of contracting a disease by the personnel and to determine the efficiency of the technical means used for preventing and removing the dust. According to the invention, the apparatus comprises a motor (9) which drives a diaphragm pump (3) carrying out the pulsatory suction of an air sample from a room, the sample being passed, in a first stage, through a separator (1) with horizontal plates, and in the second stage through a filter (10), being then discharged through some discharging holes, an electronic arrangement (12) carrying out the control of the flow rate of the air, metering and displaying the volume of the circulating air, and also the surveying of the state of a secondary battery which supplies the motor (9) and signalling the discharge thereof, controlling concomitantly the blocking of the operation of the driving motor (9).

Title: Hydraulic transformer
Inventor: DRUMEA PETRIN
IPC: F15B3/00
Filed: 2006-02-17
Abstract: The invention relates to a hydraulic transformer used in hydraulic actuation installations, wherein there is needed high pressure, but with continuous flow, without pulsations. According to the invention, the transformer comprises a parallelepipedic body (1) provided with three inner control channels, for input, output and return for a working fluid, wherein 2 slide-valves (2 and 2.1) are located, said valves having the same construction, which amplify the entering pressure by a ratio between some suitably chosen working diameters, generating a reduced flow, sucked from return column through inlet valves (3) and delivered under pressure through closing covers (4) and through other delivery valves (5), the continuity of the flow being achieved by reciprocating self-control with high frequency of the slide-valves (2 and 2.1).
