Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighbouring the serving cell or cells of the active set.

A telephone, particularly a portable handset operable in a digital radio telephone system, has a sidetone gain circuit 28 which applies one of two levels of gain G1 G2 dependent on whether a detector 30 detects a high magnitude of input signal 14 corresponding to speech or a low level of input signal 14 corresponding to an idle condition. With varying magnitude of input signal 14, the gain switches between G1 and G2 dependent on two thresholds T1 and T2 of the input signal, the relationship including hysteresis to prevent unduly rapid switching.

An orthodontic device is worn in a mouth of a patient and is attached between an upper attachment portion secured to the maxillary teeth and a lower attachment portion secured to the mandibular teeth such that the device is proximal a cheek of the patient. The device is formed from a single flexible resilient spring element having a generally curved body portion where the body portion is defined to lie in a plane relative to a plane defined by the cheek of the patient. The spring element has first and second oppositely disposed end portions where the first end portion is configured to directly attach to the upper attachment portion. The second end portion is configured to directly attach to the lower attachment portion. The spring element produces an applied force between the upper and lower attachment operative to displace the maxillary teeth relative to the mandibular teeth. The first end portion includes a primary bend that is disposed substantially within the plane of the body portion and operative to vary the effective length of the spring element where the variation in the effective length of the spring element varies the applied force directed to the maxillary and mandibular teeth. The second end portion terminates in a loop configured to attach to the lower attachment portion.

An apparatus for sandals with interchangeable upper section consists of an upper portion, a sole, and a securing system. The upper portion is the only interchangeable component, and users can interchange different upper portions with one specific sole. The securing system consists of a plurality of male connectors and a plurality of female connectors. The plurality of male connectors is connected with the sole, and the plurality of female connectors is connected with the upper portion. The upper portion can be attached to the sole, when the plurality of female connectors is traversed into the plurality of male connectors. The apparatus for sandals with interchangeable upper section consists of many different colors and styles in order to complement a wide variety of customers.

A method and system for handing off an active VoIP call with a remote party from a VoIP interface of a dual-mode device to a cellular interface of the dual-mode device. A cellular call is established between a PBX IP/PSTN gateway and the cellular interface. Media relating to the first termination point of the VoIP leg of the active call is then redirected to the cellular call and the VoIP leg is terminated.

摘要:
A method, apparatus and system for call leg selection is provided. In an embodiment, a call manger is provided which is connected to telephones that have the same telephone number. When the call manager receives an incoming call identifying that telephone number, the call manager sends a query to each of the telephones inquiring as to which telephone should receive the call. Depending on the response, the call manager will route the call to the appropriate one of the telephones.

A network node provides coverage information to wireless UE devices from a database that correlates coverage information for a radio access network with geographic area locations. The network node accepts updates to the coverage information for the radio access network via a first interface and downloads coverage information from the database to a wireless user equipment (UE) device via a second interface.
