Abstract: Series arcs in an ac circuit are discriminated from other phenomenon by analyzing the timing between pulses in a second derivative of the current signal. A first timer starts timing upon detection of a first pulse in the second derivative of current signal. Time out of the first timer starts a second timer which times a second interval or window during which a series arcing fault will generate a second pulse of opposite polarity to the first pulse. Detection of the first pulse followed by a second pulse of opposite polarity during the window sets a flip-flop to record the event. When a predetermined number of events are counted by a counter within a given time-period set by a third timer, an output signal indicating an arcing fault is generated. If the second pulse is generated before the window opens, or a third pulse occurs during the window, the flip-flop cannot be set so that other events such as the switching of a dimmer do not generate a false output signal.

Abstract: The invention provides a quick exhaust valve which allows compressed air to be smoothly supplied to and discharged from an air bag, which operates reliably even at low pressure or small quantity of air, and which is capable of a quick exhaust of air.  A valve box (11) has an opening (18) for connecting an exhaust port (17) and an air bag (A) with each other, and an inlet port (16) for compressed air.          In this valve box (11), a valve body (13) comprising an opening/closing piece (20) for the exhaust port (17) and an opposing piece (21) for the inlet port (16) is incorporated so as to be movable in a direction in which the exhaust port (17) is opened and closed.  The opening/closing piece (20) and the opposing piece (21) of the valve body (13) are formed into an acute angle, by which the opening/closing piece (20) closes the exhaust port (17) when the compressed air from the inlet port (16) is supplied.  When the supply of compressed air is stopped, the valve body (13) is moved by the air bag side pressure, causing the exhaust port (17) to open.  Thus, a quick exhaust can be attained.

Abstract: A system and method for intuitively generating computer assisted animation utilizes a transformation space in which a computer input device such as a three-dimensional drawing wand is moved to generated constructed poses from a plurality of source poses. The transformation space may be in the form of a tetrahedron with each of the four vertices representative of a source pose. At any point within the three-dimensional volume of the tetrahedron, a constructed pose may be defined based on weighted averages of the four source poses. The animator may create a sequence of animation simply by moving the drawing wand within the tetrahedron. The rate of change of the transformations of the constructed poses is controlled by the rate of movement of the drawing wand but may be altered after the sequence of constructed poses is defined. An additional aspect of the invention relates to the modification of portions of drawings by drawing a "warp" path in space to specify relative displacement from a reference point. The segment or segments affected, and the extent to which the points that comprise the segments are affected, is then specified. This technique may be adapted to create complex motions and wind, inertia, and wave effects in animated objects.

Abstract: Processing at high speed is realized. Interpolation is carried out between vertexes of a series of vertexes and a series of vertexes taken as a longer series of vertexes of a strip. Interpolation is then carried out between each vertex of the interpolated series of vertexes and corresponding vertexes. Sub-strips are then generated using each of the interpolated vertexes. In this way, processing can be carried out at high speed after finely subdividing.

Title: Battery charge level detecting device
Inventor: UKITA SUSUMU
IPC: G01R31/36
Filed: 1998-10-09
Granted: 2001-08-07
Abstract: In the area of the charge level of 20 ~ 80% where the charge level of a battery does not appear in the terminal voltage of the battery, the battery ECU estimates charge level by integrating the currents of the charge and discharge of the battery.  When the engine ECU detects that the ignition key is turned on, the motor generators are driven by the engine, and the generated electric power is accumulated in the battery.  When the area where the charge level appears in the terminal voltage, is reached, the calculation of the charge level is performed from the current and voltage at that time.  When this charge level has reached 80%, the calibration of said estimated charge level is performed by this value.  Furthermore,  it is also possible for this calibration to be prohibited when a heavy current is flowing and the error may become large in the calculation of the charge level.  By the above mentioned methods, the charge level of a battery can accurately be detected.
