Abstract: The invention relates to a perforated adhesive film (16) that will be used to glue a wall on one face of a cellular structure (10) to form a sandwich panel. The adhesive film (16) comprises at least one hole and not more than three holes (18) facing each of the cells (12) of the cellular structure (10). Preferably, the holes (18) are formed by punching an unperforated adhesive film. The holes (18) enable the formation of regular glue dabs on the ends of the partitions (14) separating cells (12) in the cellular structure (10), when the adhesive film (16) is heated before the wall is glued.

Abstract: A switching circuit operative to switch between a first and second power source to an output is disclosed. The circuit comprises a MOSFET switch electrically connected to the first and second power sources and operative to provide power from either one of the power sources to the output. The circuit includes a RC network electrically connected to a gate of the MOSFET switch. The RC network is operative to delay switching between the first and second power sources such that the second power source has the opportunity to fully ramp-up in order to provide continuous power to the output. Accordingly, the second power source can fully provide power to the output when the power is switched from the first power source to the second power source.

Abstract: A method and apparatus cancel repeatable run-out (RRO) errors in positioning on a recording medium using a RRO cancellation control voltage. The RRO cancellation includes (a) estimating a rotation period of the recording medium, (b) determining an update interval for the RRO cancellation control voltage based on the estimated rotation period and a desired number of updates to be performed per rotation, (c) updating a value of the RRO cancellation control voltage if a time period passed from a last update is greater than the update interval, and (d) applying the updated RRO cancellation voltage to control the positioning. A phase and a magnitude of the RRO cancellation control voltage may be determined for a RRO frequency range.

Abstract: The present invention provides an additional tier of authorization, which can be combined with any authorization procedures already in place for particular type of transactions. This new security schema uses variable identification number assigned to account owner as authorization signature for any transaction applied to his or her account. This additional feature allows transaction authorization process to be executed the same way regardless of whether or not particular account is participating in new authorization schema. That makes both types of accounts indistinguishable for the third party, which requested transaction.

Abstract: A method for adapting a software product to an environment is provided tat comprises providing the software product with a first portion of code including instructions for performing a predetermined function. At least one aspect of performing the predetermined function is controllable by an operating parameter value. The operating parameter value, a mutation rate and a set of probabilistic mutation criteria are stored in a second portion of code. The method further comprises, responsive to an occurrence of a predetermined event associated with the environment, using the mutation rate and the probabilistic mutation criteria to determine if the operating parameter value should mutate, and changing the operating parameter value in response to a determination that the operating parameter value should mutate.

Abstract: A host object representing a user, a service object representing a service, and a connection object linking the two may be utilized in order to provide Quality of Service (QoS). The host object and/or connection object may contain a provisioning scheme defining a limit on traffic, which can be provided through either a local or remote programming mechanism. When traffic flows through the host object and/or connection object, the appropriate provisioning scheme is utilized to determine which packets to discard.

Abstract: A method for controlling subscriber access in a network capable of establishing connections with a plurality of domains includes receiving a communication from a subscriber using a first communication network coupled to at least one other communication network, the communication optionally including a domain identifier associated with a domain on the at least one other communication network, determining whether the subscriber is authorized to access the domain based upon the domain identifier and a list of authorized domains for a virtual circuit used to receive the communication and authorizing subscriber access to the domain when the domain identifier is included in the list.

Abstract: A method and apparatus of encouraging distribution, registration, and purchase of free copyable software and other digital information which is accessed on a User's System via a Programmer's Program. Software tools which can be incorporated into a Programmer's Program allow the User to access Advanced Features of the Programmer's Program only in the presence of a valid Password which is unique to a particular Target ID generated on an ID-Target such as the User's System. Advanced features will thus re-lock if the Password is copied to another ID-target. If a valid Password is not present, the User is invited to obtain one, and provided with the means of doing so, and of installing that Password in a place accessible to the User's System on subsequent occasions. The present invention also provides Programmers with means to invoke business operations as well as computational operations with their programs, and thus to automatically obtain payment from Users who elect to obtain passwords.

Abstract: An apparatus and method of control for converting DC (direct current) power from a solar photovoltaic source to AC (alternating current) power. A novel DC-to-AC power converter topology and a novel control method are disclosed. This combination of topology and control are very well suited for photovoltaic microinverter applications. Also, a novel variant of this control method is illustrated with a number of known photovoltaic DC-to-AC power converter topologies. The primary function of both control methods is to seek the maximum power point (MPP) of the photovoltaic source with novel, iterative, perturb and observe control algorithms. The control portion of this invention discloses two related control methods, both an improvement over prior art by having greatly improved stability, dynamic response and accuracy.

Abstract: A process for automatically monitoring the packet error rate of a logical channel in a cable television DOCSIS data transmission system and automatically altering the bit rate on the channel or sending a message to a cable operator recommending a change in burst profile and bit rate. The preferred embodiment of the process comprises determining the dominant noise type and SNR of the channel and selecting a set of burst profiles best adapted for the dominant noise type and selecting an initial burst profile based upon the SNR. Then the packet error rate of the channel is monitored and compared to one or more thresholds to decide whether a change in bit rate is required to bring the packet error rate within limits. If a change is bit rate is indicated, automatically selecting a new burst profile with an appropriately changed bit rate and automatically generating and sending a UCD message defining the channel's new burst profile.
