  • Patent number: 11991572
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Publication number: 20090220170
    Abstract: A three-dimensional image spreading apparatus to transform a three-dimensional image of an object to a planar image includes an incident element and an emitting element. The incident element has a first reflective portion formed with a closed circumferential surface, an image inlet and an image outlet that incorporate with the first reflective portion to form an image transmission passage. The first reflective portion has a perimeter shrinking gradually from the image inlet to the image outlet. The image inlet is extended outwards to form an image capturing zone to get images of the object to generate a corresponding circumferential image. The image emitting element is located in the image transmission passage and has a second reflective portion corresponding to the first reflective portion to receive the circumferential image and reflect the planar image through the image outlet to an image capturing device.

  • Publication number: 20090187280
    Abstract: The present invention includes steps of: setting a first temperature and a second temperature; continuously detecting the temperature inside an ice tray in an ice machine, starting an ice making schedule as the ice tray temperature is identical to or higher than the first temperature; heating the ice tray as the ice tray temperature reaches the second temperature so as to rise the ice tray temperature up to the first temperature; and repeating the steps for continuing ice making. Through the method described above, the ice machine can utilize a judgment of temperature to form an ice making schedule, which includes an ice removing procedure, a water inflow procedure and a freezing procedure, and also can utilize the detection of the temperature variation in the ice tray to judge if the water level reaches a preset position, so as to ensure a proper water amount in the ice tray.

  • Publication number: 20090145148
    Abstract: The present invention for controlling an inflow time schedule of an ice machine includes a water inflow mechanism and a water amount control switch. The ice machine further includes a control axle, and the movement stroke of the control axle includes at least a closing locus linked to the water amount control switch for letting the water inflow mechanism to stop water inflow, and at least two opening loci which are located in the pathway of the closing locus and are linked to the water amount control switch for letting the water inflow mechanism to start water inflow. Since one closing locus is located between two opening loci, the water inflow of the water inflow mechanism will be separated into at least two times, so as to achieve a sectional water supplying effect, thereby reducing the wave motion of water in the ice tray and providing a smooth water supply.

  • Publication number: 20090031736
    Abstract: A packable ice level sensing architecture, mounted on an ice maker, for detecting an ice amount of the ice maker is disclosed. The packable ice level sensing architecture includes a sensing component and a limit structure linked to the sensing component. The sensing component is mounted at one side of the ice maker through a pivot, wherein the sensing component is foldable toward the ice maker through taking the pivot as an axle, so that the sensing component can have a sensing position and a packed position corresponding to the ice maker. The limit structure has a limit component linked to the pivot for limiting the sensing component at the sensing position or the packed position, and the sensing component can produce a pulling stroke, corresponding to the ice maker, for releasing a limiting relationship between the limit component and the pivot.
