Title: Method for monitoring and alarming hydrogen leakage of fuel-cell vehicle and system thereof
Inventor: REN MEILIN
IPC: G01M3/04
Filed: 2021-04-30
Granted: 2021-11-04
Abstract: The present disclosure relates to a method for monitoring and alarming hydrogen leakage of a fuel-cell vehicle and a system thereof. The method comprises the steps of: acquiring the current hydrogen concentration of a fuel-cell vehicle; judging whether the current hydrogen concentration is 0, if not, acquiring the measured hydrogen concentration, the hydrogen pressure drop value and the normal pressure range generated when the current hydrogen concentration of the fuel-cell vehicle is 0; judging whether the hydrogen pressure drop value exceeds the normal pressure range, if so, determining the predicted hydrogen concentration according to the measured hydrogen concentration and the hydrogen pressure drop value; judging whether the predicted hydrogen concentration exceeds the hydrogen leakage alarm threshold, and if not, determining the hydrogen leakage and issuing an alarm. According to the present disclosure, the hydrogen concentration alarm limit can be reached in advance, thereby shortening the time for monitoring and alarming hydrogen leakage.

Patent BR-0317120-B1 (BR)
Inventor: KENNEDY MICHAEL
IPC: F02D41/00
Filed: 2003-12-08
Abstract: Engine speed data N and engine fueling data MFDES are processed by a strategy (22) that multiplies (28) fueling transient data MFDES TRANSIENT and speed-based modifier data EGR_N_TRANS_MULT to develop speed-based fueling transient data. The speed-based fueling transient data is then processed according to a function (32) that correlates values of a fueling transient modifier with values of speed-based fueling transient data to develop exhaust gas recirculation modifier data. The exhaust gas recirculation modifier data and basic exhaust gas recirculation data are multiplied (34) to develop modified exhaust gas recirculation data, and exhaust gas is recirculated in accordance with the modified exhaust gas recirculation data. Using engine speed as a determinant of the extent to which the basic EGR rate should be modified during a fueling transient enables better control over certain exhaust emissions over certain speed ranges.

Title: Radio communications system with mobile subscribers - uses same radio concentrators for both public and private networks
Inventor: BRUSCH JOSEF
IPC: H04W68/00
Filed: 1976-12-30
Abstract: The radio communications system, for mobile subscribers (e.g taxis and industrial users), uses the same radio concentrators for both public and private networks. The subscribers can make both selective and general (broadcast) calls via concentrators covering a given locality. A dispatcher is provided within the required broadcast area and has a distributor which, after a given code has been selected, initiates all broadcast calls on a shared frequency. It is therefore only necessary for the dispatcher to have geographic coverage of the region covered by private traffic. A given group of subscribers can be selected from the local radio concentrators and called via the dispatcher.
