Title: Apparatus for regulating the pneumatic pressure of a motor vehicle tire
Inventor: ANZAI HIDENOBU
IPC: B60S5/04
Filed: 1993-09-22
Abstract: Abstract of the Disclosure An apparatus for regulating the pneumatic pressure of a tire according to the invention calculates the pressure difference between the specified pneumatic pressure entered therein through an input section and the actual pneumatic pressure of a tire measured by a pressure sensor and operates its air charging or discharging valve by specifying an extent of openness of the valve and a time for keeping the valve open as a function of the obtained pressure difference.          Thereafter, it calculates the rate of change in the pneumatic pressure of the tire from the actual pneumatic pressure of the tire measured for the second time during the valve is kept open and, at the same time, the pressure difference between the specified pneumatic pressure value and the actual pneumatic pressure of the tire measured for the second time.  Then, it calculates second time for keeping the valve open by dividing the pressure difference by the rate of change in the pneuma-tic pressure of the tire and operates its air charging or discharging valve by specifying for the second time the time for keeping the valve open while keeping the extent of openness of the valve same as that for the first time.

IPC: B60N2/75
Filed: 1993-09-08
Abstract: Control consoles are normally utilized to provide ready access to the operator of the controls necessary to perfom the various operating functions of the vehicle. Since vehicles, such as construction vehicles, are traversing rough terrain, it is advantageous to stabilize mouvement of the hand of the operator relative to the controls of the vehicle. In this subject arrangement a control console assembly (66) is provided and has a handrest (76) located thereon. The handrest (76) is adapted to receive the hand of the operator such that the heel of the operator's hand remains in intimate contact with a raised portion (78) of the handrest (76). A  pair of levers (106, 108) are mounted on the control console assembly (66) adjacent the handrest (76) and operatively actuated by the fingertips of the operator's hand. A rotary knob (86) is oriented on the side of the handrest (76) and operative to be rotated by the thumb of the operator's hand. The various controls for the operating function of the earthworking vehicle is controlled by the fingers of the operator without having to move the heel of his hand from the raised portion (78) of the handrest (76). This allows the operator to have a more finite and smooth control of the various operating functions of the vehicle even though his body is being jostled around due to the earthworking vehicle traversing rough terrain.

Title: Method of monitoring an area, and a device for carrying out the method
Inventor: GRUENER WILHELM
IPC: G01S13/42
Filed: 1993-12-01
Abstract: Monitoring an area with the aid of a frequency-modulated continuous-wave radar includes emitting a frequency-modulated continuous-wave transmitting signal with at least one transmitting antenna having a directional pattern whose main azimuthal direction depends on the frequency of the transmitting signal. Related to a predeterminable direction, an azimuthal region is selected, and in the selected region, an azimuthal swivelling of the directional pattern of the transmitting antenna is carried out by changing the frequency of the transmitting signal. Also in the selected region, each azimuthal value is assigned a frequency value of the transmitting signal.      The selected region is divided into a predeterminable number of azimuthal increments adjoining one another, and in each of the increments, a monotonous change of the frequency of the transmitting signal occurs. A reflected portion of the transmitting signal, which is reflected by the area to be monitored, is received with a receiving antenna, and a coherent signal processing for evaluating the receiving signal for each increment coherent signal processing is carried out.
