A multi-wavelength laser device equipped with a linear cavity along which a first direction and a second direction opposite to the first direction are defined is disclosed. The apparatus includes, along the first direction, a first optical component, a gain and Raman medium, a sum frequency generation crystal, a first second-harmonic generation crystal and a second optical component. The first optical component allows a pumping light to transmit therethrough and be incident in the first direction. The gain and Raman medium receives the pumping light from the first optical component and generates a first infrared base laser light having a first wavelength and a second infrared base laser light having a second wavelength. The first and second optical components form a laser cavity for oscillation of these two infrared base laser lights. The sum frequency generation crystal receives the first and second infrared base laser lights and generates a first visible laser light having a third wavelength. The first second-harmonic generation crystal receives the first infrared base laser light and generates a second visible laser light having a fourth wavelength. The second optical element allows the first and the second visible laser lights to emit out along the first direction.

Methods and apparatus are provided for inter-RAT bearer change for the 3GPP network. In one novel aspect, a bearer termination procedure is performed upon detecting one or more triggering events for the inter-RAT bearer modification. In one embodiment, the UE established the 4G EPS bearer. The UE successfully performs a bearer change from 4G to 3G. Subsequently, the UE detects missing mandatory parameters during inter-RAT bearer change from 3G to 2G in an idle state. The UE performs bearer termination by releasing the PDP context. In one embodiment, the PDP context is locally released. In other embodiments, the UE explicitly releases bearer using the PDP context deactivation procedure. The locally released procedure can be triggered by the UE, or by the network, or by both the UE and the network. The explicitly PDP context release procedure can be triggered by the UE, or by the network, or by both the UE and the network.

Methods and apparatus are provided for enhanced bearer continuity for the 3GPP network. In one novel aspect, the UE detects missing parameters for the inter-RAT bearer change in an idle state. The UE performs bearer preservation procedures to maintain the bearer continuity. In one embodiment, predefined/preconfigured parameter settings are used. In one embodiment, a mapping rule is used to map the missing parameter to a predefined value based on one or more known parameters. In another embodiment, the missing parameters are obtained from the network. In another embodiment, signaling procedures used to obtain the missing parameters. The signaling procedures include a service request, a UE-initiated bearer modification procedure. In one embodiment, the cell reselection is suspended such that the signaling procedure is performed to obtain the missing parameters before the cell reselection. In another embodiment, a RAU procedure is used upon detecting the missing of parameters.

A fixing mechanism for fixing a display device includes a display casing whereon a hole is formed, a shielding wall connected to a side of the display casing, and a bracket wedged inside the shielding wall in a detachable manner and installed on the side of the display casing. An opening is formed on the bracket. The fixing mechanism further includes a screwing component. An end of the screwing component passes through the hole on the display casing and is screwed inside the opening on the bracket. The other end of the screwing component is installed inside a wall mount. The shielding wall is for shielding the end of the screwing component.
