  • Patent number: 12574205
    Abstract: Disclosed herein are system, method, and computer program product embodiments for evaluating a decision tree in a privacy preserving manner. In embodiments, s first server receives a first partial share of the decision tree and encrypted input data from a client, wherein the input data comprises a set of attributes. A second server receives a second partial share of the decision tree. Each of the first server and the second server communicate with the other server to compute a classification result over the encrypted input data using the respective partial share of the decision tree received thereby and secure multi-party computation methods, including additive homomorphic encryption and oblivious transfer, such that the classification result is computed without decrypting the encrypted input data, and such that the classification result is ultimately received by the first server. The first server then transmits the classification result to the client.

  • Patent number: 12425227
    Abstract: Mechanisms are disclosed for decoupled integration of quantum-safe digital signatures into software applications. Electronic document content is stored, by a software application, in connection with a document store. An application programming interface (API) request is issued to a quantum-safe digital signature service. The API request comprises an identifier associated with the electronic document content and a request to generate a quantum-safe signature associated with the electronic document content. The request to generate a quantum-safe signature of the electronic document content causes the quantum-safe digital signature service to perform several steps. First, the electronic document content is retrieved from the document store. Next, a quantum-safe digital signature data structure is generated. Next, the quantum-safe digital signature data structure is stored to the document store. A signing status update is transmitted to the software application.

  • Publication number: 20080004637
    Abstract: A surgical clip according to an embodiment includes a pair of jaws, pivoted together, with a spring holding the jaws together. Various design embodiments incorporate this structure and include additional features such as having jaws made of an MRI invisible material, and spring connected to the jaws with hinge joints. An applicator is also provided, particularly with a ball and socket connection to the surgical clip. A method of latching the applicator, and of handling the clip with the applicator are also provided.

  • Publication number: 20070295301
    Abstract: An energy transfer machine, for example, a positive displacement internal combustion device, has a fixed or rotating outer housing, an internal rotating carrier and one or more inner rotors with rotational axes which are offset from the inner rotor carrier rotational axis. Circumferentially expandable projections from the outer housing and rotor mesh with each other to define variable volume chambers.

  • Publication number: 20070089987
    Abstract: A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the sample chamber. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.

  • Publication number: 20050159768
    Abstract: An apparatus and method for lancing a surface provides an adjustable nozzle assembly that includes an interior nozzle, a collar, and an exterior nozzle with a surface that contacts the surface to be lanced. The exterior nozzle can then rotate relative to the interior nozzle and, thereby, vary the lancing depth of a lancet. The apparatus and method for lancing a surface also provides for a rearward body assembly that includes an interior tube, a lancet holder, an internal compression spring, a retainer, a rearward body, and an external compression spring. Longitudinal movement of the rearward body away from the interior tube can compress the interior compression spring and can, thereby, spring load the lancing device. The apparatus and method for assembling the adjustable nozzle assembly of the lancing device provides for an interior nozzle with an assembly groove and a ramped groove separated by a raised boss.
