Title: Floating caisson for offshore production and drilling
Inventor: HORTON EDWARD E III
IPC: B63B39/06
Filed: 1997-02-19
Granted: 2001-11-20
Abstract: A floating caisson for offshore drilling and production that includes means for increasing the natural period of the caisson and reducing heave,  pitch,  and roll without increasing the overall length of the caisson.  The caisson is self buoyant by means of buoyancy tanks and is held in position by mooring lines.          The caisson has a center well through which drilling and/or production risers pass.  One or more plates extend radially from the  caisson below the water  surface.    The plates  provide additional mass and resistance to environmentally induced motions and thus increase the natural period of the caisson beyond the periods of maximum wave energy.  This allows the caisson to be designed with a shallower draft than a caisson without the plates that would normally be used in deep water.

Title: Network with shared caching
Inventor: GADDE SYAM
IPC: G06F17/30
Filed: 1998-03-31
Granted: 2002-07-02
Abstract: In a computer network system, the caches at individual stations are available to other stations.  A central cache directory is maintained at a network server. Each time a station caches a data object received from a remote network, it informs the central cache directory.  When a station comes online, it is asked to send a list of the contents of its cache.  Whenever a station seeks an object from the remote network, the local network server first checks the central directory cache to see if the request can be satisfied at one of the local stations.  Only if it cannot is the requested object retrieved from the remote network.

Abstract: A method, system and computer program product to facilitate royalty collection with respect to online distribution of electronically published material over a computer network. In one embodiment, a method for managing use of a digital file (that includes content subject to copyright protection on behalf of some content provider) begins by establishing a count of a number of permitted copies of the digital file. In response to a given protocol, a copy of the digital file is then selectively transferred from a source to a target. Thus, for example, the source and target may be located on the same computer with the source being a disk storage device and the target being a rendering device (e.g., a printer, a display, a sound card or the like). The method logs an indication each time the digital file is transferred from the source to a target rendering device, and the count is decremented upon each transfer. When the count reaches a given value (e.g., zero), the file is destroyed or otherwise prevented from being transferred from the source device. The indications logged are transferred to a management server to facilitate payment of royalties to the content provider.

Title: Electrical energy meter oscillator compensation
Inventor: HEMMINGER RODNEY C
IPC: G01R22/00
Filed: 1997-10-01
Granted: 2004-02-24
Abstract: Methods and apparatus for metering electrical energy are disclosed in an electronic meter which includes a first oscillator for generating a first clock signal within a first accuracy and a second oscillator for generating a second clock signal within a second accuracy. A processor, operable in relation to a clock signal, measures time and periodically compensates for the accuracy of the first oscillator. The first clock signal is used for measuring time when power is applied to the meter and the second clock signal is used by the processor for measuring time when power has been removed from the meter. The accuracy of the first oscillator is compensated periodically in relation to a compensation factor stored in memory.      In one embodiment, the processor includes a counter for counting from a first value to a second value in response to the first clock signal. In such an arrangement, the processor substitutes the first compensation factor for the first value. The meter can further include a timer, wherein the processor substitutes the first compensation factor for the first value in response to the first timer. The processor also is shown to implement a process for compensating for the accuracy of the second oscillator. This process compensates for the accuracy of the second oscillator in relation to the first oscillator. To this end, the process calculates a second compensation factor. The second compensation factor is determined when power is applied to the meter, wherein after power has been removed and restored, the second compensation factor is used to compensate time measured in relation to the second oscillator during the period power had been removed.
