Abstract: The clutch remains open as long as the vehicle is in the "no tractive drive" state. It closes as soon as the vehicle is no longer in the "no tractive drive" state. The "no tractive drive" state is recognised when the speed of a drive engine increases despite a non-disengaged accelerator pedal. The "no tractive drive state" is also recognised when on a gear input shaft a negative acceleration is detected, also when on at least one wheel of the vehicle a negative acceleration is detected. It is also recognised when an operation of a brake pedal is detected. It is then only determined when a movement of the vehicle is detected.

Abstract: A gradient calculation system efficiently calculates precise gradients
for planar surfaces of primitive (11) in computer graphics systems (18, 23)
using exact closed form solutions. The system is particularly suited for
calculating gradients to enable selection of an appropriate texture map
resolution in a texture mapping system (27). In architecture, the gradient
calculation system can be implemented in software (18), hardware (23), or a
combination thereof, and is more particularly implemented as follows. A
texture mapping system (27) is provided with a plurality (14) of MIP maps
(14a - 14d) with different texel (15) resolutions. A gradient calculation
system associated with the texture mapping system (27) computes texel
(15) gradients relative to a pixel (13) of a primitive (11) using closed form
equations that result in exact gradients. MIP map selection logic (27)
associated with the texture mapping system (27) selects an appropriate
MIP map (14a - 14d) for the pixel (13) from the plurality (14) of MIP maps
(14a - 14d) based upon the calculated exact gradients. Optionally, the
system may further include a performance optimization feature (38) for
assigning the appropriate MIP map (14a - 14d) to subsequent pixels (13)
of, preferably, the entire primitive (11), or secondarily, to subsequent
pixels (13) of a span (12) of the primitive (11), when certain gradient
criteria are met.

Title: Method and device for the remote operation and remote control of systems and apparatus via a telephone network
Inventor: STOLZ HELMUT
IPC: H04M11/00
Filed: 1997-11-29
Abstract: The known methods and devices, which resemble the remote access systems for answering machines, do not provide sufficient protection against copying and manipulation. With the modified method, the establishment of connections between the base station and the adapters is made dependent on a unilateral authentication process. Before making his DTMF (dual tone multi-frequency dialling) selection, the user identifies himself with respect to the base station using coded data which comprise a "key" and a "secret" and are tested there for conformity with stored data concerning authorized persons. If conformity exists, readiness for connection to an adapter is acknowledged by means of a first ready signal. It is only then that, in a similarly coded manner, the adapter and type of actuation, which are acknowledged by status signals or a further ready signal, are selected. The method even enables critical functions with greater demands as concerns security to be remotely controlled via the public telephone network, for which dedicated lines would otherwise be necessary.

Abstract: To enable the production of a connector having a smaller thickness. 
     A group of upper side male terminal fittings 2A and lower side male terminal
fittings 2B are secured to the upper and lower surfaces of a mount plate 8
formed as a separate piece by pressing projections 12 into mount holes 16,
thereby forming a core member 7. A housing 1 is formed by insert molding
using this core member 7 as a core material. Since insert molding can be
performed with the outer surfaces of the male terminal fittings 2A, 2B opposite
from those secured to the mount plate 8 exposed, only the thickness of the
housing 1 is added at the outer surfaces of the male terminal fittings 2A, 2B.
Thus, there can be obtained a connector having a small thickness T around the
male terminal fittings 2A, 2B.

Abstract: The method uses an additional charge from the exhaust system (7) in a low RPM range, so that the exhaust valve (6) is opened at the beginning of a compression stroke. After the valve is closed, the exhaust gas fed into the combustion chamber is used to compress the chamber volume via the piston (2). At the end of the compression stroke, the exhaust valve is opened and the exhaust gas is blown out of the chamber via the exhaust valve into the exhaust system. Opening timing and opening duration of the exhaust valve are continuously regulated dependant upon exhaust temperature and engine RPM.

bore and enlarges the bore to a desired diameter while simultaneously pulling in a utility line.
A set of cutting elements (14) supported near the first end of the shaft, with 120 degree spacing
therebetween, enlarges the bore to an intermediate diameter. A series of blades (16,18,20) are supported
on the shaft between the precutting elements and the second end. The first blade further

edge, the first blade (16) comprises a plurality of teeth (72) adapted to slice through the wall of the
bore. Following the first blade are a second (18) and a third (20) blade, each of which churn the spoils
created by the first blade. A central passageway (32) through the shaft transmits drilling fluid to
fluid jets (34) positioned near the blades and the cutting elements. The fluid jets clean the blades
during the reaming operation and inject fluid into the formation to mix slurry and lubricate the
equipment. The device is lighter than conventional backreamers due to its unique design and
configuration, yet dramatically increases the penetration and productivity rates over
conventional backreamers.
