Title: Guiding motor vehicle driver when changing traffic lanes - using radar devices to detect velocity and spacing of vehicles in next lane and indicate when lane changing is possible
Inventor: BERNHARD WERNER DIPL ING
IPC: G01S13/931
Filed: 1993-04-26
Granted: 1994-06-16
Abstract: A method for providing guiding assistance for a motor vehicle in changing lane from a current lane 8 to an adjacent target lane 9, in which the space 22 in front and the space 21 behind at least in the adjacent target lane for the desired lane change is monitored by radius, the distance s0l, s02, s03 and s04, fig. 2) from objects, in particular vehicles, detected there, and their speeds are measured and safety distances (sw01, sw02, sw03 and sw04) calculated therefrom. If all the measured distances are greater than the calculated safety distances, this is detected as a possible immediate lane change. If an immediate lane change is not possible, the target lane is checked for gaps in the traffic stream which are longer than the sum of the forward (sw03) and rearward (sw01) safety distances appertaining to that lane. The driver is thus relieved to the greatest possible extent of the task of monitoring and estimating distances and speeds of vehicles which are travelling behind and travelling in front. <IMAGE>

Abstract: FIELD: wood working industry. SUBSTANCE: formed wood-particle briquette 5 is placed between upper heating plate 1 and lower heating plate 2 of hot press heated to 180-190 C. Briquette 5 is compressed with pressure of 3.0 MPa and heated to attain temperature in mat middle layer of 102-107 C. Then, briquette 5 is held for 60-80 s for binder hardening. Further on, press system is communicated with vacuum pump to create rarefaction of 0.1 MPa, and ammonia is supplied at pressure of 0.5-0.6 MPa through system of channels in lower heating plate 2. As a result, vapor-gas mixture is removed from wood-particle briquette 5, and it is saturated with ammonia. Ammonia treatment is lasted for 10-20 s. Ammonia supply is discontinued and its remaining amount is removed from stack by blowing with atmospheric air. Then, before unloading boards from press, they are conditioned by vacuum method with no contact of upper heating plate with treated boards.
