Methods and systems for hitless switch management module failover and upgrade are disclosed. According to one method, a master switch management module participates in network protocols and performs packet forwarding operations. The master switch management module distributes protocol state and packet forwarding information to the slave switch management module. The slave switch management module continuously monitors the operational state of the master switch management module. In response to detecting failure of the master switch management module or a forced failover initiated by the user interface on the master switch management module, the slave switch management module begins network protocol operation in the master mode in a state where the master switch management module last operated correctly.

The present invention includes various embodiments of a BSA system that facilitates the collection of relevant health-related data on a continuous basis, integrates such data with pertinent personal and aggregate information, enables users to purchase (directly and indirectly) health-related goods and services, and provides credit, discounts and other economic benefits in connection with such purchases that are determined dynamically based upon the nature and extent of users' interaction with the system. The BSA system facilitates a dynamic feedback process by continually monitoring user interaction and medical and financial behavior, which results in dynamic adjustments to their credit levels and offers of discounts and other promotions, which in turn incentivizes users to continue participating in the process (thereby modifying their system interactions and behavior, and thus perpetuating this feedback loop). As a result, users are incentivized to actively participate in the process and thereby enhance their wellness while reducing healthcare costs.

A neurological control system for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a “nervous system component.” The neurological control system generates neural modulation signals delivered to a nervous system component through one or more neuromodulators to control neurological state and prevent neurological signs and symptoms. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors, each configured to sense a particular characteristic indicative of a neurological or psychiatric condition.

A method and apparatus for controlling power consumption of a facility, building or simply a collection of one or more devices, by load shedding when power consumption is above, or is predicted to be above, a preselected setpoint, but only if electrical power on the spot market cannot be purchased at or below a preselected price. The apparatus and method of the invention optimizes power usage by taking advantage of the buying of electricity as a commodity on the spot market. As a further aspect of the invention, in the situation of a supermarket for example, which refrigerates food products, artificial product core temperature sensors or direct insertion product sensors can be used to continuously monitor the refrigerated temperature of perishable products. A controller would constantly monitor these temperatures to allow a precise load shedding routine to be implemented.

In a method of recalibrating continuous glucose monitoring data from a user, operable on a digital processor, an indication from the user that the user has taken a meal is received (806). A self-monitored of blood glucose levels from the user (810) at two separate times during a day corresponding to when the user has taken a meal. A glucose signal is received from a continuous glucose monitoring sensor (818) at times corresponding to the two separate times that the user has taken a meal. Two reconstructed blood glucose values based on the glucose signal from the continuous monitoring sensor at times when the at least two self-monitored of blood glucose levels are received from the user. A linear regression is performed (822) using y=ax+b, wherein x corresponds to the two reconstructed blood glucose values and y corresponds to the two self-monitored of blood glucose levels thereby generating an estimation of a and b. A recalibration signal, including the estimation of a and b, is transmitted to the continuous glucose monitoring sensor (824) based on the linear regression.

The method and system may comprise hardware or software (or both) may adjust one or more algorithms based on whether tissue being monitored was traumatized or is healthy. The method and system can also monitor the relationship between blood pressure and oxygenation levels and activate alarms based on predetermined conditions relating to the oxygenation levels or blood pressure or both.

Described herein is a method of calibrating a three-dimensional imaging system. During calibration, a position and an orientation of the three-dimensional imaging system is determined with respect to a first parameter comprising a real world vertical direction (V_w) and to a second parameter comprising an origin of a three-dimensional scene captured by the imaging system. The first and second parameters are used to derive a calibration matrix (M_C2w) which is used to convert measurements from a virtual coordinate system (M_c) of the three-dimensional imaging system into a real coordinate system (M_w) related to the real world. The calibration matrix (M_C2w) is used to rectify measurements prior to signal processing. An inverse calibration matrix (M_w2c) is also determined. Continuous monitoring and adjustment of the setup of the three-dimensional imaging system is carried out and the calibration matrix (M_c2w) and its inverse (M_w2c) are adjusted accordingly.

The system includes a hemodialysis machine for performing the hemodialysis process that features a controller, a pump, a dialyzer filter, a lumen, and an interface to a body-worn monitor. A patient attaches to the dialysis machine through the lumen, and wears a body-worn monitor for continuously measuring blood pressure. The monitor includes an optical system for measuring an optical waveform, an electrical system for measuring an electrical waveform, and a processing component for determining a transit time between the optical and electrical waveforms and then calculating a blood pressure value from the transit time. The body-worn monitor features an interface (e.g. a wired serial interface, or a wireless interface) to transmit the blood pressure value to the controller within the hemodialysis machine. The controller is configured to receive the blood pressure value, analyze it, and in response adjust the dialysis process.

A computer implemented method and system for optimizing performance of a business IT infrastructure, wherein business objectives are obtained as input and the IT business infrastructure and/or business level components associated therewith are optimized according to the business objectives. In one embodiment, an objectives definition is created that defines business objectives and business rules determining how IT level metrics affect the business objectives and, optionally, service level agreements or other contract definitions based on the objectives definition. A runtime performance of the business objectives is determined during runtime of the business IT infrastructure by monitoring the business IT infrastructure, its compliance with the contract definitions, and the business objectives achieved by the business IT infrastructure. If a statistically significant change is detected between the runtime performance and a reference optimization of the business objectives, the business model is updated and the reference optimization of the business objectives is re-determined.
