摘要： An alternate approach to meeting the harmonic current limits specified in EN61000-3-2 for power supplies, which fall under the classification of Class A equipment and also provide universal input voltages. In use, an electronic switch(triac) is used as the simple switch between low line input(90-132 VAC) and high line input(180-254 VAC) to provide an auto ranging front end. An inductor is placed in series with the input bridge diodes to increase the conduction angle of the input line current, thereby, increasing the power factor of the supply. This inductor is switched in series with the bulk capacitor whenever the triac is off. In this way, the harmonics are reduced at high line only, and the supply runs unaffected with low power factor at low line. Thus the harmonic currents are reduced at the test voltage of 230V without the need for an active power factor corrective front end.

摘要： A temperature sensor for monitoring an organ or tissue is configured to measure a temperature inside of a container configured to contain the organ or tissue. The temperature sensor is disposed exterior to the organ container and the temperature sensor is a non-contact temperature sensor. The temperature sensor may be part of an apparatus for perfusing, transporting, and/or storing an organ or tissue. A coolant container may have an aperture through which the temperature sensor measures a temperature of at least one of the organ or tissue or a perfusate fluid surrounding the organ or tissue. The temperature sensor is preferably an infrared temperature sensor. Multiple temperature sensors may be provided that measure the temperature organ or tissue or perfusate fluid surrounding the organ or tissue, for example in case one of the temperature sensors fails.

摘要： A method is disclosed that receives, at a sink device, encrypted content. Further, the method receives, at the sink device, content license data from a source device. In addition, the method analyzes the content license data to determine whether a rights issuer that generated the content license data intended that the source device, which has cryptographic access to the content license data, be authorized to send, to the sink device, a value that enables decryption of the encrypted content. The method also receives the value and decrypts the encrypted content if the rights issuer intended that the source device be authorized to transfer the value to the sink device.

摘要： An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Preventing overpressurization prevents or reduces damage to vascular endothelial lining and to organ tissue in general. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.

摘要： An organ perfusion apparatus may include at least two tubes connected to an organ or tissue. A method of perfusing an organ or tissue may include connecting a first end of each of the at least two tubes to an organ or tissue, applying a fluid motive force to a perfusion fluid in the two tubes to force the fluid through the two tubes into the organ or tissue, and perfusing the organ or tissue through the at least two tubes such that the fluid motive force, provided by, e.g., a pump, and backpressure generated by the organ or tissue, establishes a flow balance between the at least two tubes. The flow balance may be altered without altering the fluid motive force that is applied.
