Abstract: An overvoltage protection circuit (16) for electronic equipment, such as telecommunications equipment (10), computers and instrumentation equipment, having tip and ring lines (TR) includes a first voltage sensitive switch (30) having first and second terminals. The first terminal of the first switch is connected to the tip line (T). A second voltage sensitive switch (32) includes first and second terminals. The first terminal thereof is connected to the second terminal of the first voltage sensitive switch (30), and the second terminal thereof is connected to the ring line (R). A third voltage sensitive switch (34) includes first and second terminals. The first terminal is connected to the second terminal of the first voltage sensitive switch and to the first terminal of the second voltage sensitive switch. The second terminal of the third voltage sensitive switch is connected to ground potential. The switches are conductive when a respective voltage threshold is exceeded. In one embodiment, the sum of the voltage thresholds of the first and third voltage sensitive switches is approximately equal to the sum of the voltage thresholds of the second and third voltage sensitive switches, such that the circuit is conductive when either of the thresholds of the first and third voltage sensitive switches or the second and third voltage sensitive switches are exceeded. In another embodiment, the holding current of the third voltage sensitive switch is lower than that of either the first or second switch. In this combination, the third switch turns on first, then both the first and second switches turn on in unison and hold the lines in balance during switching.

Abstract: The invention relates to a door hinge allowing the end of the door closing movement to be a perfect translatory motion after a substantially rotatory motion, and vice versa in the reversed movement when opening the door. Between two mounting parts (1) and (2) for the wall (17) and the door (18), respectively there is a connecting piece consisting of two parts, a first part of which consists of a hinging parallelogram formed by two parallel swivel links (6) and (7), which are pivotally connected on the one hand around pin-shaped axes (10) and (11) to the door mounting part (2) and on the other hand around pin-shaped axes (8) and (9) to a connecting link (3), which forms the second part of the connecting piece. This connecting link (3) is with its extended part swivellingly connected around a pin-shaped axis (4) to the wall mounting part (1), which comprises a curve disc (14) with a stop (14.1) and a cylinder-shaped curve path (14.2). The swivel link (7) comprises a guide roller (15) capable of co-operating with the curve disc (14) over the curve path (14.2). The guide roller (15) has been positioned in such a way that as soon as it reaches the curve path (14.2) the curve disc (14) will be clasped between the connecting link (3) and the guide roller (15), as a result of which the guide roller (15) can follow only the curve path (14.2), so that the closing movement will change over to a completely forced translatory motion.

Granted: 1995-03-07
Abstract: A solenoid current control system includes a microprocessor which periodically generates a desired peak current value and which energizes the solenoid coil.  Current through the coil is sensed via a series resistor and the sensed current is compared to the desired peak current by comparator.  The comparator generates an interrupt signal when the sensed current reaches the desired peak value.  The interrupt signal is applied to the microprocessor which responds by de-energizing the coil.

Title: Glare control lamp and reflector assembly and method for glare control
Inventor: GORDIN MYRON K
IPC: F21V7/04
Filed: 1990-02-09
Granted: 1996-03-19
Abstract: A glare control lamp and reflector assembly and method for glare control which includes a conventional lamp and symmetrical reflector for providing a controlled light beam to a target area.  A reflector shield can be positioned on the reflector below the lamp and has the properties of diverging incident light downwardly towards the target area and thus controls reflection upwardly which would produce glare.  A glare shield can be positioned on the top of the reflector and extends outwardly from the outer edge of the reflector to block both direct light and reflected light from traveling upwardly and outwardly which would produce glare.  In a further combination, a lamp shield can be positioned over a portion of the outermost extending end of the lamp to prevent unreflected light from directly causing glare. The method for controlling glare includes the steps of providing a conventional lamp and reflector assembly, positioning a reflector shield in the bottom of the reflector beneath the bulb to converge instant light downwardly to the target area, and providing a glare shield extending around and outwardly from the top of the reflector to block and divert incident light downwardly towards the target area.  An additional step would be to provide a lamp shield over the outwardmost end of the lamp to block direclty emanating light from causing glare.     A still further feature and embodiment of the invention includes an arc shield which is positioned directly adjacent to the arc of the arc lamp used with the glare control lamp and reflector assembly.  The arc shield serves to block and redirect light from a short distance from the arc in an accurate and efficient manner without much loss of useful light.  The arc shield can be used individually or in combination with any of the reflector shields, glare shields, and lamp shields.

Title: Communication circuit fault detector
Inventor: YAMADA YOSHIKO
IPC: H04L69/40
Filed: 1990-05-25
Granted: 1998-05-12
Abstract: A communication circuit fault detector tests a communication circuit by using a sequence generator to generate a test signal, a memory circuit to temporarily store the test signal, and a multiplexer to multiplex the test signal and an input data signal into the communication circuit.  A timing generator drives the communication circuit at a rate higher than the normal communication rate, enabling the data signal and test signal to be sent through the communication circuit simultaneously.  A demultiplexer demultiplexes the output signal from the communication circuit into an output data signal and a returned test signal. A comparator compares the returned test signal with the test signal stored in the memory circuit and generates a result signal indicating whether they match.

Title: Variable stroke metering pump with damping and pump cycle duration control
Inventor: SANTI FRANCO
IPC: F04B9/08

Granted: 1997-05-13
Abstract: Pump units comprising a metering reciprocating pump with adjustable length of stroke are used in packing machines for filling of packing containers with a metered quantity of flowable contents, e.g. yoghurt.            Adjustments in the length of stroke in order to adapt the amount of filling goods to the volume of the packing container interferes with the breaking sequence at the extreme position of the piston and alters the time for each pumping stroke.            These drawbacks are avoided by means of an arrangement which includes a movable braking device (16) for the piston (6) as well as a valve arrangement (10,11) which is linked to the braking device (16) and serves to adapt the speed of the piston to the length of stroke.

Title: Method and apparatus for adaptive phong shading
Inventor: WELLS STUART
IPC: G06T15/83
Filed: 1991-06-28
Granted: 2001-03-20
Abstract: In the method and apparatus of the present invention an adaptive shading method is utilized to generate shaded images in real time. The color or intensity is first computed at each of the vertices of the polygon. A series of tests are then performed to determine the order equation that is to be used to interpolate the color or intensity across the polygon between the vertices.  Using this technique, polygons having a slight or no curvature and an infinite light source (thus being the simplest form of shading), will use an extremely fast, low order equation to interpolate across the polygon. Polygons, having a high degree of curvature and/or positional light source will utilize, as necessary, a higher order equation which requires additional computation time but produces desirable shading results.
