摘要:
The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermister 23), of gases flowing through a heated tube (3), supplying gases to a patient, which utilises the heating wire (21, 28) within the tube.
摘要:
A breathing assistance system is provided for delivering a flow of gases to a user. The system includes a humidifier unit which holds and heats a volume of water, and which in use receives a flow of gases from a gases source via an inlet port. The flow of gases passes through the humidifier and exits via an exit port. The system further having a temperature sensor which measures the temperature of the gases exiting the humidifier unit, an ambient temperature sensor which measures the temperature of gases before they enter the humidifier unit, and a flow sensor which measures the flow rate of the gases stream. The system also has a controller which receives data from the temperature and flow sensors, and which determines a control output in response. The control output is configured to adjust the power to the humidifier unit to achieve a desired output at the humidifier unit exit port.
摘要:
A computer system module includes a system management controller to negotiate with other system management controllers to determine the controller's initial operational state. In an embodiment, negotiation with other system management controllers is based at least in part on one of controller capability, user configured preferences, module type, and geographical address.
摘要:
In a vehicle an auxiliary machine (13) such as an air compressor is physically associated with the vehicle battery (12). The battery provides for substantial additional mass which resists transmission of noise and vibration from the small machine to the vehicle structure (11). The small machine (13) may itself form part of a battery clamp arrangement.

摘要:
A method of determining the number of magnetic particles within a sample using a tuned circuit having a capacitor and a coil. The method comprises: a. determining the difference in the resonant frequency of the tuned circuit when the sample is exposed to a magnetic field generated by the coil and when the sample is not exposed to the magnetic field generated by the coil; and b. using the difference in the resonant frequency to determine the number of magnetic particles within the sample.

摘要:
In an active system, an actor is able to effect action in a subject system. The actor and the subject system exist in an environment which can impact the subject system. Neither the actor nor the subject system has any control over the environment. The actor includes a model and a processor. The processor is guided by the model. The processor is arranged to effect action in the subject system. The subject system is known by the model. This allows the actor to be guided in its action on the subject system by the model of the subject system. Events can occur in the subject system either through the actions of the actor, as guided by the model, or through actions of other actors, or through a change in state of the subject system itself (e.g. the progression of a chemical reaction) or its environment (e.g. the passage of time). The actor keeps the model updated with its own actions. When the processor is processing according to the model, it updates the model with intermediate actions and with the actions it effects in the subject system.
摘要:
A hijack avoidance technique avoids presenting an access to more than one of a chain of authentication objects, such as a chain of Lightweight Directory Access Protocol (LDAP) authenticators. A pre-filter determines whether an authentication object should be presented with the access by comparing either all or a portion of a domain suffix, an IP address, or other identification other than the user ID with predetermined values. If the filter criterion is met, the associated authentication object accepts or rejects the access. Otherwise, the access is passed to the next authentication object in the chain. The first authentication object may be associated with a hosting entity and successive authentication objects each associated with different customers of the hosting entity. By virtue of the filtering, each authentication object is presented only with a particular subset of all of the possible access identifiers, which avoids presenting all of the previously unauthenticated accesses to each authentication object in the chain.
