Abstract: A dialysis system includes a fluidics system configured to perform a dialysis treatment session for a patient by having sensor(s) that measure corresponding parameter(s) and having dialysis actuator(s) that configures fluid flow through the fluidics system. The dialysis system includes a communication subsystem configured to communicatively connect to user device(s). A controller of the dialysis system is communicatively coupled to the fluidics system and the communication subsystem. The controller operates the fluidics system to perform the dialysis treatment session. The controller maintains data associated with the fluidics system. The data includes data types of patient health information, de-identified health information; and non-health information. The controller identifies access rights associated with first credential used by a first user device to the data types and communicates the data types to the first user device according to the access rights.

Abstract: A catheter, a catheter system, and a processing system including said catheter or catheter system for determining one or more parameters of tissue of an anatomical structure within a region of interest. The catheter comprising at least two electrodes. The electrical responses of the least two electrodes mounted on the catheter with mutually fixed electrode distance are monitored, and used to derive the parameters.

Abstract: A local content server system (LCS) for creating a secure environment for digital content is disclosed, which system comprises: a communications port in communication for connecting the LCS via a network to at least one Secure Electronic Content Distributor (SECD), which SECD is capable of storing a plurality of data sets, is capable of receiving a request to transfer at least one content data set, and is capable of transmitting the at least one content data set in a secured transmission; a rewritable storage medium whereby content received from outside the LCS may be stored and retrieved; a domain processor that imposes rules and procedures for content being transferred between the LCS and devices outside the LCS; and a programmable address module which can be programmed with an identification code uniquely associated with the LCS. The LCS is provided with rules and procedures for accepting and transmitting content data.

Abstract: A system and methods for permitting open access to data objects and for securing data within the data objects is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. The method includes the steps of (1) providing a data object comprising digital data and file format information; (2) embedding independent data into a data object; and (3) scrambling the data object to degrade the data object to a predetermined signal quality level. The steps of embedding and scrambling may be performed until a predetermined condition is met. The method may also include the steps of descrambling the data object to upgrade the data object to a predetermined signal quality level, and decoding the embedded independent data. The additional steps of descrambling and decoding may be performed until a predetermined condition is met.

Abstract: The present invention relates to methods for protecting a data signal using the following techniques: applying a data reduction technique to reduce the data signal into a reduced data signal; subtracting the reduced data signal from the data signal to produce a remainder signal; embedding a first watermark into the reduced data signal to produce a watermarked, reduced data signal; and adding the watermarked, reduced data signal to the remainder signal to produce an output signal. A second watermark may be embedded into the remainder signal before the final addition step. Further, cryptographic techniques may be used to encrypt the reduced data signals and to encrypt the remainder signals before the final addition step.
