Patent EP-0681362-A1 (EP)
Inventor: PEDRAZZINI GIORGIO
IPC: H02M3/156
Filed: 1994-05-06
Abstract: A fully digital, current mode, PWM control is realized by employing two distinct comparators (COMP1,COMP2), both reading the voltage drop on a sensing resistance (Rsense). The first comparator (COMP1) exerts an open-loop current mode control. The second comparator (COMP2), establishing a second higher current threshold than the current threshold set by the first comparator (COMP1), triggers a disabling circuit of the output power transistor for a preset period of time, when the current level through the output stage uncontrollably rises beyond the second threshold. This may occur because of an insufficient discharge from the load circuit inductance (L) during off-phases of the output power transistor of the extra energy stored during switching delay periods of the first (open loop control) comparator (COMP1). 
     The frequency of the sequence of bursts may be precisely controlled to be well outside the frequency range of interest to prevent disturbances.

Inventor: MURNICK JANET GEORGE
IPC: A61B5/097
Filed: 1994-02-07
Abstract: A breath sampling device (20) has a body (22) defining an interior space (21) or bore with two open ends (24,33). The patient's breath is directed through the device from end to end, thereby continually purging the interior space. At a designated time during the breath, closure devices (50,52) are actuated to shut both ends, desirably in response to a single actuation movement, thereby capturing a breath sample at a predetermined time. The continual purging action assures that the captured breath sample truly represents the breath at the designated time during the exhalation cycle.

Abstract: An apparatus for controlling an automated video cassette library is provided which is actuated in response to command signals originated by an individual at a location remote from such apparatus to transfer a select video cassette in a horizontal plane from a cassette shelf to a cassette player each of which is located in a compact housing. The apparatus is then ready for use by another individual who may select another video cassette for playing upon another video player each of which is located in the same housing. The cassette player plays the video cassette and communicates the recorded program to the individual's television set. Upon completion of each play, the video cassette is rewound and automatically transferred from the cassette player to the cassette shelf.

Title: Gas replenishment method and apparatus for excimer lasers
Inventor: SANDSTROM RICHARD L
IPC: H01S3/036
Filed: 1994-08-31
Abstract: An excimer gas laser using a fluorine/krypton/neon gas mixture is provided with separate fluorine/neon (32) and krypton/neon (34) gas sources for use in replenishing the gas mixture. A bleed-down (36) mechanism is also provided for draining a portion of the gas mixture from the excimer laser. A control mechanism (44) controls operation of the separate fluorine/neon (32) and krypton/neon (34) source and the bleed-down (36) mechanism to selectively vary the gas mixture within the excimer laser to maintain an overall optimal laser efficiency. Preferably, the control system (44) monitors operational parameters of the excimer laser including gain, wavelength, bandwidth and pulse rate, to determine whether the gas mixture within the excimer laser may have changed from an optimal mixture. The control system controls operation of the separate fluorine/neon and krypton/neon sources to compensate for changes in the operation parameters of the laser to thereby maintain high overall laser efficiency. Alternatively, gas replenishment is controlled subject to pre-determined empirically-based gas replenishment strategies.

Abstract: A collator comprises a first hopper (21) for storing signatures having a first characteristic and a second hopper (22) for storing signatures having a second characteristic. A plurality of collating pockets (11,12) move relative to the first and second hoppers and receive signatures from the first and second hoppers. An actuatable feeder (25,26), when actuated, feeds an individual signature from one of the first and second hoppers (21,22). A memory (34) stores a predetermined number corresponding to the number of individual signatures to be delivered from the first hopper (21). The feeder (25) is controlled to initially feed individual signatures from the first hopper to the plurality of pockets (11,12) until the number of individual signatures delivered equals the predetermined number and then to feed individual signatures from the second hopper (22) to the plurality of pockets (11,12) without stopping movement of the pockets relative to the first and second hoppers.

Abstract: An individual person mobility simulator includes a base for placement on a support surface, a steering post extending upwardly from the base to terminate in an upper end, a seat mounted on the upper end of the steering post on which a human operator may sit, a torque/position sensor disposed between the seat and the steering post to sense changes in seat position caused by the operator, and foot stirrups into which the operator may place his feet, said foot stirrups being movably mounted on the steering post. A power source is provided to supply a resistive force to movement of the foot stirrups in response to and dependent upon resistance signals. A control unit supplies resistance signals to the power source to determine the amount of resistance to be applied to movement of the foot stirrups. The amount of resistance is geared to simulate the steepness of terrain over which the operator is moving, with greater resistance being applied when the terrain is uphill and less resistance being applied when the terrain is level or downhill, for example.

Abstract: A first pipe (23) press-fitted into a second pipe (24) having an inner peripheral surface circular in section about an axis of the second pipe. The first pipe, having an outer peripheral surface provided with recesses (26) each located between arcuate portions, are formed into an arcuate shape with the same radius about an axis of the first pipe at a plurality of circumferentially spaced-apart points. The recesses are located radially inwardly of phantom extensions (25a) of the arcuate portions (25) to extend axially over a predetermined length of the first pipe. Thus, it is possible to relatively enlarge the press-fit margin leading to an elongation limit and to set the dimensional accuracy of the pipe product at a relatively low value by the fact that when the first pipe is press-fitted into the second pipe, the second pipe flows so as to fill a gap produced between the first and second pipes due to the plurality of recesses provided on the outer peripheral surface of the first pipe, as well as by the fact that the first pipe is easy to deform under compression at the recesses.
