Abstract: A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.

Abstract: Provided herein are devices and methods for isolation and detection of an analyte from a sample. In some embodiments, provided herein are devices and methods of use thereof for vertical flow-based isolation and detection of analytes in a liquid sample, such as a urine sample.

Abstract: A system and method for establishing a secure execution environment for a software process analyzes system application program interface (API) calls to determine whether the system API call executes a new program. If the system API call executes a new program, the system and method of the invention analyze the call to determine whether an execution environment, in the form of a plurality of attributes, is attached to an executable program file associated with the new program. An execution environment contains security attributes that are to be associated with the resulting process invoked by execution of the new program. If an execution environment is attached, the invention assigns the attributes of the execution environment to the new process, thereby ensuring that the new process includes the security features and capabilities specified in the execution environment.

Abstract: A method of monitoring browser interactions with a server arrangement includes: capturing information regarding requests and corresponding responses; identifying sessions, each session including requests received at the server arrangement and corresponding responses; assigning a session identification (SessionID) for each identified session; recording in a database the SessionID, the content of each respective request in the session, the content of each corresponding response, and a chronological order of the requests; and re-creating selected pages representative of a particular browser's interactions and identifying browsing patterns.

Abstract: The present invention provides a method and apparatus for restricting a process or process hierarchy to a subset of a computer host's file system(s) in an environment where all file systems are simultaneously available to an application. A caller is provided with the ability to arrange for the restriction of a process hierarchy (consisting of a process and all the processes it may subsequently create) to a set of file system sub-hierarchies. When a process executes within a restriction domain in which a sub-hierarchy has been specified for each of the available file systems, an embodiment of the invention will modify the usual operation of the host computer's operating system interface such that any file system access attempts by the affected process are constrained to occur logically within the restriction domain.
