Abstract: A time base error signal generating apparatus which outputs a phase difference signal (o) representing a phase difference between a horizontal sync signal (Pb-H) and a reference signal (Ref-H) as a time base error signal. In accordance with the phase status of a vertical sync signal (Pb-V) with respect to a reference signal (Ref-V), supply of the horizontal sync signal or reference signal to a phase comparator is inhibited (2,4). Thereby, a single phase comparator can detect the phase difference while avoiding problems such as a phase offset.

Abstract: A reciprocating pump (10) substantially eliminates cavitation problems without imposing capacity and flow limitations to maintain a net positive suction head. The pump comprises a cylinder (12) having a liquid inlet (16) and a liquid outlet (52), a piston (14) reciprocably movable within the cylinder between the inlet and outlet and having a liquid flow conduit (20) therethrough, a piston rod (32) for reciprocably moving the piston within the cylinder and a valve (24) operatively associated with the piston rod for alternately opening and closing the conduit, the valve being closed when the piston rod and piston are moved in the direction towards the cylinder outlet and being open when the piston rod and piston are moved in the reciprocal direction. Preferably, the pump comprises a piston having a hollow conical bore (20) which makes a close confirming fit over a conical discharge valve housing (50) when the piston reaches the bottom of its stroke. The top rim (30) of the piston serves as an inlet valve seat for an inlet valve (24) which is completely opened by the piston rod (32) before the piston (14) begins to rise away from the conical housing. As the piston begins to rise, it opens a pumping chamber between the piston bore and the bottom housing into which the saturated liquid smoothly flows under the gravitational force of the overlying fluid column. Cavitation is largely eliminated since the hollow piston moves upwards through essentially static liquid, and any minor vaporization bubbles migrate upwards along the conical bore and out of the still-open inlet valve, rather than collapse in the pumping chamber.

Abstract: The invention relates to a transmission system for the synchronous digital hierarchy, having at least one adapter circuit for compensating phase fluctuations of an STM-N signal. The adapter circuit (8) contains a buffer memory (17, 51), a write-address generator (16, 53), a read-address generator (18, 61), a stuffing- decision circuit (24, 60) and an output circuit (19, 62) for insertion of stuffing digits for at least one container of the STM-N signal. The buffer memory is intended for feeding in data of the container and for reading out data of the container. The write-address generator is intended for forming write addresses for the data to be written in and the read-address generator is intended for forming read addresses for the data to be read out. In a first solution, the stuffing-decision circuit is used for forming a stuffing signal from the combination of difference values of the addresses of the read-and write-address generator and of low-pass-filtered values from values which contain the stuffing information of the data of the container to be written in. In a second solution, the stuffing-decision circuit is used for forming low-pass-filter difference values from the addresses of the read-and write-address generator and of a stuffing signal from the low-pass-filtered difference values. The output circuit is intended for forming negative or positive stuffing digits in the container in dependence on the stuffing signal and for forming an output signal from the data stored in at least one buffer memory. <IMAGE>

Abstract: The present invention provides a long range LADAR (Laser Detection and Ranging), that employs in combination a 1.32 micron, Q-switched, diode-pumped Nd:YLF laser whose output beam is linearly polarized. A quarter-wave plate is positioned in front of the laser such that the laser's (e.g. vertical)polarized light is converted to right circular polarization. Reflection from a specular surface returns left circular polarized light. A second quarter-wave plate transforms the left circular polarized light to horizontally polarized light which is then propagated through a beam splitter to two Gallium Arsenide Avalanche Photo-Diode detectors. This invention provides both substantial reduction in eye injury potential and good transmission in the atmosphere while improving scattering performance.

Abstract: A mechanism having at least one output element is positioned by controlled movement of joints of the mechanism in response to joint control signals, representing joint variables, which are generated by a controller based on a kinematic model of the mechanism, which model resides in control software. The control software includes parameters which may be adjusted to account for the effect of variation, over time, of lengths or angles in the mechanism, which occur due to such causes as compliance under load, thermal expansion and wear. Sensors are provided for external observation of the position of one or more parts of the mechanism in response to a set of joint variables, and from a sufficient number of such observations in response to generally different joint control variables, the parameters are automatically adapted by maximal likelihood estimation, considering known standard deviations describing uncertainties in the external observations. Such observations and the adaption of the parameters may be performed during normal operation of the mechanism. Additionally, for the purpose of reducing time and development expense, the control software is generated by compiling a kinematic description file relating frames of reference fixed with respect to bodies of the mechanism.

Abstract: In a data communication system a plurality of users are equipped with respective devices for computation and authentication of message authenticators. Each device stores a common cryptographic function; a common secret key and a respective non-secret offset for the key. They are programmed to perform the functions of: (i) computing and outputting an authenticator for an entered message using the cryptographic function and key combined with the respective offset; and (ii) computing an authenticator for an entered message using the cryptographic function and key combined with any entered offset, comparing that authenticator with one received with the message and displaying a "pass" or "fail" decision. The devices are incapable of displaying or otherwise outputting any authenticator computed using any offset other than its respective stored offset, however. In this way it can be ensured that a transmitted authenticator can act as a verifiable "signature" to a message uniquely identifying the sender.
