Inventor: WOLF MICHAEL
IPC: H03L7/085
Filed: 1999-07-05
Abstract: Network elements of a synchronous digital communications system have a clock generator for generating a clock signal locked to an input signal.    Such a clock generator comprises a tunable oscillator (OSC) and a phase comparator (PK) for comparing the phase of the input signal (IN) with the phase of the clock signal (CLK) and for generating a correction signal which serves to tune the oscillator (OSC). To avoid phase transients due to interruptions and disturbances in the input signal (IN), means (WD) are provided for determining an expectancy window, for deciding whether the correction signal lies within the expectancy window, and for tuning the oscillator with the correction signal if the correction signal lies within the expectancy window.

Title: Optical circulator
Inventor: AU-YEUNG VINCENT
IPC: G02F1/09
Filed: 1998-11-17
Abstract: An improved optical circulator transfers light from a first optical port to a second optical port, and from the second port to a third port. The circulator has reciprocal polarization rotators (16-A, -B; 18-A, -B) and non-reciprocal polarization rotators (20-A, -B), birefringent beam splitters and combiners (14-A, -B), and a birefringent walk-off element (26) as well as a polarization-dependent light bending device comprising two tapered birefringent plates (22, 24). The light bending device compensates for an angle between a first light beam emanating from the first port and a second light beam propagating to the third port. The existence of this angle allows the first and third fibers to be coupled to the light beams using a single lens.

Abstract: A no-mess portable enclosure is adapted for holding sand and/or toys and facilitates play with the sand and/or toys without allowing same to escape the enclosure. The enclosure is usable indoors or outdoors and is easily portable from one location to another without fear that the sand or other contents will be spilled. The enclosure is highly aesthetically pleasing and enhances the surrounding area.      Also, it is usable by multiple people simultaneously. The no-mess play area includes an enclosure defining a hollow interior region adapted for receipt of sand, toys, and the like, wherein at least a portion of the enclosure is defined from a transparent material. At least first and second arm access assemblies are connected to the enclosure and are spaced relative to each other so as to be adapted for respective simultaneous receipt of left and right arms of a child or other user. The arm access assemblies each include a flexible sleeve having a first end sealingly positioned in an opening in the enclosure and a closed second end extending into the hollow interior region of the enclosure. Each of the sleeves is adapted for receipt of one of the left and right arms of the first child. Thus, once a child inserts his/her arms and hands into the sleeves, the child is able to play with the sand, toys, and other items held by the enclosure, but the sleeves and the enclosure, itself, prevent spillage of the sand or removal of other objects from the enclosure.

Title: Transmitting revisions with digital signatures
Inventor: EPSTEIN MICHAEL
IPC: G06F21/64
Filed: 1998-12-28
Abstract: In a computer network, documents are produced, the document is hashed to produce a fingerprint, and the fingerprint is encrypted to sign the document, then the document signature is transmitted from the user system to a secure computer system. The secure computer system creates a time stamp including the document signature and a digital time. The secure system signs the time stamp to verify its origin. The time stamp and notary's signature are transmitted from the secure system to the user's system. The user has access to the notary's public key which is used to determine whether the time stamp is authentic. Then the document is revised, the revised document is hashed and the hash is combined with an indication that the revision is related to the original document. The indication could be a hash of the original document, the original document signature, the notary's time stamp for the original document, or the notary's signature for the original document.
