Abstract: A method of controlling a wearable device including a signal generator, two stimulation electrodes, and two sensing electrodes to monitor a level of edema of a subject, includes generating, by the generator, a signal that causes a current to flow between the stimulation electrodes and measuring an impedance between the sensing electrodes disposed on a skin of the subject at an interval of time during a testing period, thereby providing impedance measurements, validating each impedance measurement against a model set of impedance measurements, eliminating a measurement from the impedance measurements if the measurement fails the validating, thereby providing a validated sub-set of impedance measurements, converting each of the validated sub-set of impedance measurements to an edema index, thereby providing edema indices, averaging the edema indices and generating an average edema index for the testing period, and generating an alert depending on the average edema index.

Abstract: A technique for managing a boot process on a data storage system having multiple storage processors is disclosed. A first storage processor communicatively coupled to and directs a second storage processor to perform one or more boot sequences. Elapsed time and timeout variables and an empty set of boot states are provided. After sleeping for a predetermined time the elapsed time variable is incremented. If the boot state of the second processor is not successful, the technique determines if the current boot state is a new boot state, and if so, the new boot state is added to the set of boot states and the elapsed time value is reset. The timeout value is set equal to the user defined value. If the elapsed time is less than the timeout value, the technique loops back to the sleep state and continues thereon, else if greater that the timeout value, a failure is indicated.

When software is initialized, its release level is determined. A feature limit manager separate from the software being initialized is invoked. At least the software program identifier, the release level, and the feature identifier are provided as input to the feature limit manager. The feature limit manager provides a feature limit value. The feature limit value is stored and the software uses the feature limit value to enforce the feature limit during execution.

Abstract: A method allows point-in-time viewing of session data for multiple sessions being stored on a disk. Session bits are set for the session data in memory which points to the data at any particular point in time, and this can be done for multiple sessions. In order to make the session data persistent, separate session bits are stored in a portion of a disk reserved for such session bits. Thus, in the event of failure where session bits which are stored in volatile memory such as RAM, are lost, the duplicate copy set in the non-volatile memory can be used to recreate the session once the failure is corrected.
