Title: Temperature control for free-piston cryocooler with gas bearings
Inventor: KEITER DOUGLAS E
IPC: F25B13/00
Filed: 2005-03-25
Abstract: A cryocooler having two operating modes so that its operating range is broadened, its gas bearing system is maintained in an operable state and it can utilize piston stroke modulation for energy efficiency. A piston stroke modulator modulates the piston stroke when the commanded piston stroke exceeds the minimum stroke and maintains the minimum stroke when the commanded stroke is less than the minimum stroke. A heater applies heater power to the thermal load when the commanded piston stroke is less than the minimum piston stroke. A closed loop feedback control system is used which has two branches of its dynamic leg. One branch controls the modulation of the cryocooler and the second, parallel branch controls the modulation of the heater. ® KIPO & WIPO 2007

Then, the base station receives a downlink signal level report message from the mobile terminal(704). In case the mobile terminal's signal level reported through the downlink signal level report message is below a critical value(706), the base station transmits a handover request message to a heterogeneous system(708). Based on the handover request message, the heterogeneous system allocates a channel to a cell to which the mobile terminal will move, and transmits channel allocation information to the base station(710). Receiving the channel allocation information, the base station transmits a message containing the received channel allocation information to the mobile terminal(712).

Title: A method and apparatus for measurement using communication gap in a wireless communications system
Inventor: JEONG KYEONG IN
IPC: H04B7/26
Filed: 2007-02-12
Abstract: A measurement method using communication gaps in a mobile communication system and an apparatus thereof are provided to implement efficient communication by minimizing the signaling overhead to inform an ENB(Evolved Node B) that measurement for neighbor cells has been completed before an actual gap period expires. A UE(User Equipment) carries out measurement for not a serving frequency bandwidth but other frequency bandwidths during an allocated gap period. If the measurement is completed before the gap period expires(401), the UE calculates an effective remaining gap period which remains until the gap period expires(403,405). Based on the calculated effective remaining gap period, the UE judges whether to perform signaling to inform an ENB that the measurement has been completed before the gap period expires(407). The UE performs or doesn't perform signaling according to a judgement result(411,413). In this case, if the effective remaining gap period is larger than or equal to a preset comparative threshold period, the UE transmits a signaling message to the ENB.
