Abstract: A switch for switching a packet within a communications network includes a switching core that services a number of ports. The switch also includes address matching logic, coupled to the switching core, that implements an address lookup scheme according to which the switching core may switch to packet received at the switch. Override logic, that is also coupled to the switching core, determines with a packet received at any one of the number of ports serviced by the switching core is received at a predetermined port. This may be done by snooping a bus within the switch that provides an indication of an active port. If the packet was not received at the predetermined port, the override logic override the address matching logic to cause the switching core to route the packet exclusively to the first port.

Abstract: An inductive write head includes a first pole and a second pole that form a yoke having a write gap between the first pole and second pole. The second pole is formed of a particular Co100-a-bZRaCRb compound. More specifically, the second pole is formed where “a” is in the range of about 2 atomic percent to about 18 atomic percent, and “b” is in the range of about 0.5 atomic percent to about 6 atomic percent. The magnetic write element also includes a conductive coil which lies between the first pole and the second pole. The inductive write head also includes a first yoke pedestal attached to the first pole, and a second yoke pedestal attached to the second pole, with the write gap formed therebetween. Further, the first yoke pedestal has a pedestal width that defines the write element trackwidth and that is smaller than the pedestal width of the second yoke pedestal.

Abstract: Bias layers for a magnetoresistive (MR) sensor have an in-plane easy axis of magnetization for providing a longitudinal bias to MR layers. The bias layers include cobalt (Co), and are formed on various underlayers having crystalline structures that encourage an in-plane alignment of the C-axis of that Co. Preferred underlayers include nickel aluminum (NiAl) and magnesium oxide (MgO), and an interlayer containing chromium (Cr) may be interposed between a bias layer and an underlayer.

Abstract: A system and method are disclosed that enable exclusive rights in generic goods to be transferred from one party to another. A party holds an exclusive right to a good through a rescindable capability. When two parties agree on a transfer of the exclusive right to the good, a goods description memorializing the agreement is created which is in synergy with the rescindable capability. The goods description includes an acquire method that is the only method that can extract rights from the rescindable capability with which it is in synergy. The object from which the generic right is being transferred sends a message to the recipient with a reference to the rescindable capability. Upon receiving the message, the recipient invokes the acquire method of the referenced goods description, which returns a new rescindable capability that encompasses the generic right just transferred. Once the recipient holds a reference to the new rescindable capability, the sender has had its rights rescinded.

Abstract: A sensor has an interferometer which measures a change in an applied environmental condition relative to a reference environmental condition. The interferometer is operated under the applied environmental condition to generate an interference spectrum. Intensities of the interference spectrum are measured at first and second wavelengths, respectively. The first and second wavelengths correspond to first and second reference intensities that lie on respective sides of an extremum in the interference spectrum when the interferometer is operated under the reference condition. Measurement of the change in the applied environmental condition is based on the measured intensities and the first and second reference intensities.

Abstract: A system and method is disclosed that provides persistent capabilities for distributed, object-oriented applications running on generally available hardware. The disclosed system and method operate in a transparent distributed object system where inter-process messaging between the program objects is effected by paired transport managers, proxies and matched in-table and out-table slots. Each object needing to communicate with an object in another address space does so by transparently issuing messages to that object's local proxy. Each process provides a registrar that includes a secret code table wherein an object is registered with a unique, practically unguessable secret code. Anticipating the need to re-establish object-proxy links following a inter-process communications fault, proxies are made revivable, meaning that their links with corresponding remote objects can be revived following a communications interruption.

The composition is an aqueous gel matrix of ester vesicles which is provided by a mixture of diacetyl tartaric acid mono fatty acid glyceride ester and a second ester having a hydrophilic-lipophilic balance of above about 10 and a melting point above about 100.degree. F.

Abstract: A distributed garbage collection system and method is disclosed that is compatible with local ref-count or full garbage collection and that ensures that no local object's storage is deleted by the local garbage collector unless it is certain that there are no actual or potential remote references to that local object. The disclosed system and method are implemented in the context of a transparent distributed object system in which communications between objects in different processes are enabled by dedicated proxy objects that are linked to corresponding remote objects via a pair of transport objects. Additional proxy holder objects and proxy holder proxies ensure that objects for which third-party object references are passed (i.e., where one object in a first process passes a remote object in a second process a reference to a third object in a third process) are not collected until a direct link is established between the remote object in the second process and the third object in the third object space.

Abstract: A system providing capability security for distributed object systems is disclosed. The basic tenet of capability security is that the right to do something to an object (e.g., invoke a particular object's methods) is represented solely by the holding of a reference to that object. In each of the preferred embodiments described herein, an object is presumed to hold legitimately a reference to a particular object only if the object knows some unpublicized (except under the conditions required by capability security) key associated with the particular object. That is, an object's key is required along with the object's reference. So that capability security is preserved when object references are passed between objects in different processes, the object references being passed are encrypted upon transmission and then decrypted upon arrival at their intended destination.

Abstract: A system and method is disclosed that provides lightweight non-repudiability for networked computer systems. Each party to a two-party communication maintains hashes on its incoming and outgoing messages. At its discretion, either party can request that the other party commit to the conversation. The second party (if it agrees) then sends signed hashes that third parties can use to verify the content of the conversation. The party requesting the commitment stores its corresponding hashes when it sends the request. If the hashes from both parties are the same for the same positions in their conversation, the two parties can verify that their conversation is error-free. If the sending party also maintains logs of both sides (incoming and outgoing) of the conversation and stores hashes corresponding to the beginning of the logs, the sending party is also able to verify to a third party that the logged portion of the conversation was between the first party and the second party.

Abstract: A diverse goods arbitration system and method allocates computer resources among bidding requesters. Bid slates are transmitted to an arbiter by users (requesters) requesting use of specified portions of the available computer resources. Each bid slate may contain a plurality of bids, each bid representing a requested set of resources and a bid price. The arbiter selects combinations of bids from the bid slates, where each bid combination consists of no more than one bid from each of the received bid slates. The arbiter rejects all bid combinations whose constituent bids exceed an established maximum allocation level for any computer resource. It then selects as a winning bid combination the bid combination having the highest total bid price. Computer resources are then allocated for a next time period based on the winning bid. Costs are allocating to each successful requester in accordance with a predefined opportunity cost function.

Abstract: A low-fat natural cheese is manufactured from skim milk or skim milk cheese. In one embodiment of the invention, a gel-forming fat mimetic is added to skim milk to provide a cheese substrate. The gel-forming fat mimetic may be gelled in situ or may be pregelled. The cheese substrate is then subjected to a cheese make procedure to provide a cheese curd. The cheese curd is then cured to provide a low-fat skim milk cheese. The skim milk cheese is comminuted and heated to a temperature of from about 140.degree. F. to about 180.degree. F. for a period of time sufficient to provide a homogeneous cheese mass. The cheese mass is then packaged to provide a low-fat natural cheese.

Abstract: A method of making stable, low-calorie emulsion-type dressings wherein the triglyceride oil is replaced wholly or partially with an edible, wholly or partially nondigestible, low-calorie polyol fatty acid polyester is provided. A preemulsion containing at least a portion of the polyol fatty acid polyester, preferably sucrose fatty acid polyester, is prepared in a thickened gum solution. The preemulsion is then combined with the remaining ingredients. Stable mayonnaise-type products can be prepared containing about 40 to 60 weight percent polyol fatty acid polyesters. By incorporating a starch, viscous salad dressings containing about 12 to 50 weight percent polyol fatty acid polyesters can be prepared. The mayonnaise-type products can be used as a base for pourable salad dressings containing about 12 to 50 weight percent polyol fatty acid polyesters.

Abstract: Low-fat or reduced-fat chocolate products containing sucrose fatty acid polyesters are provided which have texture and mouthfeel properties similar to conventional chocolate products. These chocolate products are prepared using a sucrose fatty acid polyester or a blend of sucrose fatty acid polyesters in place of the conventional cocoa butter constituent. The sucrose fatty acid polyesters used do not necessarily mimic the theological and thermal properties of cocoa butter. Rather, the desired texture and mouthfeel properties of the chocolate products of this invention are obtained by incorporating a hydrogenated or hardened oil (i.e., a hardstock triglyceride) and an emulsifier selected from the group consisting of lactylated glycerides, sorbitan esters, acetylated glycerides, polysorbate esters, and polyglycerol esters, along with the one or more sucrose fatty acid polyesters, into conventional chocolate formulations containing essentially no cocoa butter or substantially reduced levels of cocoa butter.
