  • Publication number: 20150276943
    Abstract: The present invention provides a thermal management system, an X-ray detection device and a CT apparatus. The thermal management system comprises a heater, an air mixing portion and a fan. The heater is provided at an air inlet of the air mixing portion. The air mixing portion provides an air mixing space for mixing exterior air that enters the air mixing portion with interior air of the air mixing portion. The fan is provided at an air outlet of the air mixing portion, and supplies the mixed air in the air mixing portion to a target object to be thermally managed. Therefore, a response time of the thermal management system to operate for an external temperature change may be lengthened, thus occurrence of abrupt change in a temperature of the target object as the external temperature changes abruptly may be avoided, improving a reliability of the thermal management system.

  • Patent number: 9099915
    Abstract: Congruent power and timing signals in a single electronic device. In an embodiment, a circuit may include just one isolation transformer operable to generate a power signal and a timing signal. On the secondary side, two branches may extract both a power signal and a clock signal for use in the circuit on the isolated secondary side. The first branch may be coupled to the transformer and operable to manipulate the signal into a power signal, such as a 5V DC signal. Likewise, the second circuit branch is operable to manipulate the signal into a clock signal, such as a 5 V signal with a frequency of 1 MHz. By extracting both a power supply signal and a clock signal from the same isolation transformer on the secondary side, valuable space may be saved on an integrated circuit device with only having a single winding for a single isolation transformer.
