The safety-first rule involves creating a minimum acceptable return, or threshold return. By fixing a threshold return, an investor aims to reduce the risk of not achieving the investment return. The safety-first rule, also called Roy's safety-first criterion (SFRatio), is a quantitative risk-management investment technique.
Method and apparatus for controlling a ventilator
Method and apparatus for controlling a ventilator are described. The invention can be used to control mechanical ventilators as well as respiratory assist devices such as CPAP machines. The apparatus receives input data indicative of patient's oxygen level. A controller determines PEEP, or CPAP, and FIO2, on the basis of data indicative of the patient's oxygen level. In an alternative embodiment, the apparatus further receives input data indicative of patient's carbon dioxide levels, respiratory elastance and airway resistance, and barometric pressure. The controller further utilizes the said input data to determine the optimal values of tidal volume and breathing frequency for a next breath of the patient, and uses the respiratory elastance and airway resistance data to determine any necessary adjustments in the I:E ratio. The controller also applies safety rules, detects and corrects artifacts, and generates warning signals when needed.

Firewall propagation
InactiveUS7853998B2Unauthorized memory use protectionHardware monitoringService provisionSecurity policy
Methods and systems for propagating data security policies and rules up a chain of network components, for example, from an end-user device having a firewall, to a network component at the “edge” of the network, from where a policy statement can be transmitted to a service provider are described. A device, such as a computer or mobile phone, has, as part of its firewall software, a policy propagation file, that communicates with pre-existing firewall software. The firewall software creates a policy statement upon detecting a triggering event, which is transmitted from the device to the next data security component up the chain, “upstream,” in the network. The firewall server may combine policy statements from numerous end-user type devices and transmit the policy statement to an external network component. The ISP or other service provider may then use the policy statement to implement data security rules for the devices in the network.

Techniques for controlling an insulin pump include determining values for parameters selected from a group including a first prediction time horizon, a predicted glucose threshold (Goff) for turning the insulin pump off, a maximum shut off time within a time window, and duration of the time window. A safety rule is determined based on the maximum shut off time within the duration. Glucose readings are collected up to a current time. An expected current glucose value G and glucose temporal rate of change are determined based only on the glucose readings and a Kalman filter configured for noisy glucose readings. A glucose level (Gh1) is predicted for a future time that is the prediction time horizon after the current time. A command is issued to shut off the insulin pump if it is determined both that Gh1 is less than Goff and that the safety rule is satisfied.
