The present invention includes methods, devices and systems for isolating, identifying, analyzing, and quantifying biological materials from fluid samples. In various aspects, the methods, devices and systems may allow for a rapid procedure that requires a minimal amount of material and/or results in high purity biological materials from complex fluids such as blood, serum, or plasma.

Methods and devices for detection of multiple analytes from a biological sample

Disclosed are cartridge components, cartridges, systems, and methods for isolating analytes from biological samples. In various aspects, the cartridge components, cartridges, systems, and methods may allow for a rapid procedure that requires a minimal amount of material from complex fluids.

Disposable fluidic cartridge and components

The present disclosure describes methods, devices and systems comprising materials comprising dielectrics. In various aspects, electrodes layered or imbedded with these dielectrics provide enhanced properties for a wide range of applications, such as the enhanced separation of analytes, such as biological molecules or particles (nucleic acids, viruses) with an electrokinetic field.

Dielectric materials

Compact device for detection of nanoscale analytes

A method is provided for safely executing dynamically generated code to avoid the possibility of an attack in unprotected memory space. Upon ascertaining that dynamically generated code is to be executed, a processing circuit and/or operating system kernel restrict the dynamically generated code to use a first memory region within an unprotected memory space, where the first memory region is distinct (e.g., reserved) from other memory regions used by other processes executed by the processing circuit. A first processing stack is maintained for the dynamically generated code within the first memory region. This first processing stack is separate from a general processing stack used by other processes executed by the processing circuit. A stack pointer is switched/pointed to the first processing stack when the dynamically generated code is executed and the stack pointer is switched/pointed to the general processing stack when the dynamically generated code ends.

Dynamically generated code process sandboxing using authenticated pointers

Systems, devices, media, methods, and kits are disclosed to integrate and exchange information of analyte analysis kits. Analyte analysis can be performed and presented using in association with advertising or questions.

Methods and systems for analyte information processing

The present invention includes methods, devices and systems for isolating a nucleic acid from a fluid comprising cells. In various aspects, the methods, devices and systems may allow for a rapid procedure that requires a minimal amount of material and/or results in high purity nucleic acid isolated from complex fluids such as blood or environmental samples.

Nucleic acid sample preparation

A method of producing a control stack includes: writing a plurality of control information entries into a control stack buffer that is internal to a processor in response to one or more function calls; and in response to the control stack buffer being full and receiving a further function call, writing: the plurality of control information entries to an external memory that is external to the processor; and a further control information entry, corresponding to the further function call, to the control stack buffer.

Authenticated control stacks

Techniques for enforcing flow control of a software program in a processor are provided. An example method according to these techniques includes analyzing program code of the software program to identify a code pointer in the program code, generating an authentication tag based on the code pointer, and modifying the code pointer in the program code with the authentication tag to generate a tagged code pointer.

Code pointer authentication for hardware flow control

Techniques for protecting contents of a stack associated with a processor are provided. The techniques include a method including receiving a store instruction from a software program being executed by the processor, the store instruction including control information associated with a subroutine, altering the control information to generate secured control information responsive to receiving the store instruction from the software program, storing the secured control information on the stack, receiving a load instruction from the software program; and responsive to receiving the load instruction from the software program, loading the secured control information from the stack, altering the secured control information to recover the control information, and returning the control information to the software program.
