  • Publication number: 20100149785
    Abstract: An automated de-icing system for a low power lighting device having a light emitting face. The system includes one or more detectors for detecting conditions under which ice, frost or snow are likely to occur on the light emitting face. The system further includes a heat transfer system for transferring heat to the light emitting face and a controller for receiving data from the detector(s) and determining a likelihood of ice, frost or snow forming on the light emitting face. The controller engages the heat transfer system if the likelihood of ice, frost or snow forming on the light emitting face exceeds a threshold.

  • Publication number: 20090172191
    Abstract: A computer-implemented method routes service requests to services in a service framework provided by a plurality of hosts. The method comprises receiving a service request for a service in the service framework and discovering a plurality of candidate hosts that host the service. The plurality of candidate hosts are a subset of the plurality of hosts. The method further comprises selecting a candidate host from the plurality of candidate hosts based on measured latencies for the plurality of candidate hosts and routing the service request to the selected candidate host.

  • Publication number: 20080204029
    Abstract: The system consists of an LED failure detection circuit to provide protection against individual LED catastrophic failure. When LED clusters are arranged in a series-parallel configuration, it is important to detect individual LED failure in order to avoid uncontrolled luminous intensity reduction and/or light uniformity degradation. The circuit compares the voltage levels on LEDs with similar position but situated in different chains. In normal conditions, the voltage levels are substantially similar to one another. In case of individual or multiple LED failure, open or shortcircuit, the circuit sends a signal to the automatic turn off circuit that initiates the lamp forced turn off sequence.

  • Publication number: 20080067544
    Abstract: The invention relates to a method for producing a strained layer. Said method comprises the following steps: placing the layer on a substrate and straining it, structuring the strained layer, relaxing the layer, producing directional off-sets in the layer to be strained. A layered structure produced in this manner has triaxially strained layers.

  • Publication number: 20070078484
    Abstract: A surgical grasper is provided. The grasper comprises a handle, two jaws operably connected to the handle, which jaws can be actuated by the handle, and a sensor. A surgical grasper for use in robotic surgery is also provided. The grasper comprises a shaft, two jaws at a distal end of the shaft, which jaws can be actuated in response to a robot command, and a sensor. A method for measuring an amount of force being applied by a jaw of a grasper is also provided. The method comprises the steps of: providing a grasper comprising a handle and two jaws operably connected to the handle, which jaws can be actuated by the handle; providing a sensor on the grasper; and, providing for measuring an amount of force being applied to the sensor. A method for measuring an amount of force being applied by a jaw of a grasper for use in robotic surgery is also provided.

  • Publication number: 20050065817
    Abstract: A healthcare system is provided for a care-giving facility. The healthcare system has a medical device, a user interface, a first central computer, and a second central computer. The first central computer has a first database and a first functional feature set associated with the data and functions related to the medical device and the user interface. The medical device and user interface communicate directly with first central computer. The second central computer has a second database and a second functional feature set. The first central computer is securely connected to the second computer, and the medical device and the user interface do not communicate directly with the second central computer. The user interface can receive data from the second database relating to the second functional feature set of the second central computer through the first central computer.

  • Publication number: 20030141981
    Abstract: A system and method for operating medical devices is provided. The system and method may be used to program an infusion pump. The system may be implemented in a variety of ways including as a computer program. The system may include a first computer at a pharmacy and a second computer at a treatment location. The system sends operating parameters to the medical device after providing various checks to assure that the correct medication is being administered to the correct patient. The system may also include features for confirming the operating parameters are still valid and features for sending alarms to the treatment location if there are discrepancies between the operating parameters, medication identifiers, and/or patient identifiers.

  • Publication number: 20030140928
    Abstract: A system and method for providing medical treatment, such as medication, to a patient. The administration of the medication may include the use of an infusion pump. The system may be implemented in a variety of ways including as a computer program. The computer program accessing information related to the identity of a clinician, the identity of a patient, the identity of a medical treatment, and the identity of a medical device. The computer program determines whether the medical treatment has been previously associated with the patient and whether a plurality of operating parameters for the medical device are consistent with the medical treatment. The computer program also includes logic for providing a first error signal if the medical treatment has not been previously identified with the patient; and a second error signal if the operating parameters for the medical device are not consistent with the medical treatment.
