Abstract: Positional sensors receive light that has been reflected off a pair of complementary geometric patterns carried by a supporting carrier surface that is displaceable with respect to the sensors. The sensors view the patterns through viewing windows as the carrier surface and sensors are displaced laterally with respect to each other, presenting differing portions of the patterns to the sensors. The patterns are shaped to produce outputs which, when their difference value is extracted, provide output signals that are a measure of the displacement of the carrier surface with respect to the sensors and in which common mode errors are minimized.

Title: Method for high speed data transfer
Inventor: STERLING EDWARD W II
IPC: G06F13/00
Filed: 1989-11-21
Abstract: ABSTRACT            The  method  of  this  invention  comprises  an  efficient technique   for   transfer   of   information   over communication link between first and second processors, the processors employing blocks of data on a repetitive basis.  Each processor includes means for storing copies of used blocks of data.  A block of data currently used (or displayed) in the second processor is called an "old" data block and a block of data to be transmitted from the first processor to the second processor is called "new" data block.  The method includes the steps of storing identical copies of used data blocks and the old data block in the memories of the first and second processors. The  new  data  block  is  then  compared  in  the  first processor to stored data block copies to determine if the new  data  block  equals  a  pre-established  level  of similarity with any of the stored data block copies.  If a stored data block is found to equal the pre-established level of similarity with the new data block, the method contemplates  transmission  to  the  second  processor  of information regarding the differences between the new data block and the similar stored data block, as well as the  identity of the  similar  stored data block.   The second processor then proceeds to access its copy of the identified similar stored data block and to alter that data block in accordance with the difference information transmitted from the first processor.

Abstract: A shaft synchronous balancing apparatus wherein a rotor to be balanced is rotated in conjunction with appropriate balance plane located transducers and a non-contacting shaft monitoring pick-up, for example of an optical variety. The latter pick-up derives a one times per revolution reference signal which is treated by a software driven process control system including dual timer-counters to evaluate the period of revolution, T, and to develop N incremental sampling pulses having a duration or time constant of T/N. Preferably, N is an even integer power of 2. Periodic updating of the duration of a time constant is developed utilizing only one software interrupt in conjunction with the two counter timers. A nulling technique for canceling offset at the signal treatment stages is provided which accommodates for the high amplification levels necessary at the front end of the system. Additionally, a gain adjust feature achieves optimum precision and reliability for the system by performing within three discrete ranges.

Abstract: In a snap locking mechanism for rotary switches an operating shaft (4) operable by a switch handle can be rotated against the force of an energy-storage mechanism and each lock-in position is occupied with at least partial release of the energy-storage mechanism.  The energy-storage mechanism is formed by axially acting compression springs (8) and acts on a driver ring (6) exhibiting slopes in the peripheral direction which interacts with another driver ring (13), couplable with the operating shaft, exhibiting a corresponding counterprofile with slopes.  A coupling for dragged slaving (28, 29) is provided between the two driver rings (6, 13).  Handle-side driver ring (6) carries stops (11) on its front facing away from these slopes, which interact with counterstops (12), integral with the housing, when they reach the snap position of the locking mechanism.    Two annular links (14, 15) placed concentrically to the slopes of driver rings (6,13), each of which is operative for one direction of rotation each and which exhibit on their front sawteeth inclined in the opposite direction to one another running in the peripheral direction and which interact respectively with a corresponding counterprofile on handle-side driver ring (6) or in housing (2) (Fig. 1).

Title: Stage programmable light sequencer for a toy
Inventor: LEHMANN ROGER W
IPC: H05B37/02
Filed: 1990-06-21
Abstract: STAGE PROGRAMMABLE LIGHT SEQUENCER FOR A TOY                  ABSTRACT         A light sequencer for a toy having a simple means for individually varying the on and off time of each stage of the chain or ring.  Each stage comprises a light controlling amplifier/switch whose gain is individually controlled by a hysteresis element.          When the voltage presented across a hysteresis element prior to breakdown, is below its set breakdown voltage, the hysteresis element is in its' non-conductive state, thereby causing the amplifier/switch to have negative gain.  The light being controlled receives no voltage and is not lit.  When the voltage presented across a hysteresis element prior to breakdown equals or exceeds its set breakdown voltage, the hysteresis element 'fires' into a highly-conductive state, thereby causing the amplifier/switch to have very high gain.  The light being controlled receives its full voltage and is lit.  The hysteresis element remains in its highly-conductive state until the voltage presented across it drops below its recovery voltage level. When this occurs, the hysteresis element switches back to its non-conductive state, thereby causing the amplifier/switch to have negative gain.  The light being controlled receives no voltage and is not lit.  The difference between the breakdown or 'firing' voltage and the recovery voltage is the hysteresis factor.  Having this hysteresis factor control the gain of an amplifier/switch enables the use of a simple Resistor-Capacitor circuit in between the stages to control the on and off times of each stage in the chain, and consequently the period time of the chain or loop time of a ring.  The resistor and capacitor values of each stage can be made different from its peers, thereby causing a pseudo-random appearing affect, thereby provoking greater interest on the part of the viewer.
