Abstract: A mechanism for securely locking and easily releasing a wireless device in a cradle is comprised of a release button located on an outer housing, accessible to a user. The release button extends through the outer housing to an interior in the cradle. An actuator is disposed in the housing and has an arm extending into the interior receptacle area of the cradle, wherein movement of the arm activates the mechanism. A lever is disposed within the housing and is rotatable between a first and a second position. A first end of the lever is located adjacent to the actuator, while a second end of the lever is located adjacent to the release button. A protrusion extends from the lever into the receptacle area when the lever is in the first position and is housed inside the housing when the lever is rotated to the second position. A spring connects the actuator to the lever.

Abstract: A computerized model provides a display of a physical environment in which a communications network is or will be installed. The communications network is comprised of several components, each of which are selected by the design engineer and which are represented in the display. Errors in the selection of certain selected components for the communications network are identified by their attributes or frequency characteristics as well as by their interconnection compatibility for a particular design. The effects of changes in frequency on component performance are modeled and the results are displayed to the design engineer. A bill of materials is automatically checked for faults and generated for the design system and provided to the design engineer. For ease of design, the design engineer can cluster several different preferred components into component kits, and then select these component kits for use in the design or deployment process.

Abstract: The invention provides a mobile communication apparatus of the diversity system including a plurality of transmitter-receivers of different transmission/reception systems wherein a drop of the antenna reception sensitivity of one system by an output from the antenna of the other system is minimized and the synchronism keeping accuracy is augmented and besides unnecessary dissipation of power is prevented.

Abstract: A communications device for interfacing a computer to a cellular telephone which includes memory, voicemail, caller identification and a display screen includes a housing accessible to a human operator, a telephone interface attached to the housing to communicatively connect to the cellular telephone, a telephone connection to connect to a telephone line; and means for uploading the voicemail of the cellular telephone via the telephone connection and telephone interface to the memory of the cellular telephone. Attaching the cellular telephone to the telephone interface actuates the uploading of the voicemail of the cellular telephone to the memory of the cellular telephone for display in the display screen of the cellular telephone.
