Abstract: A signal wire connecting between a hand-free receiver and a mobile telephone includes a first side having a hand-free receiver plug co-operating with the hand-free receiver so as to be connected to the main circuit of the hand-free receiver, and a second side having a mobile telephone plug co-operating with the output receptacle of the mobile telephone so as to be connected to the mobile telephone. In such a manner, the mobile telephone plug includes a voltage control leg provided with a first branch resistor which is adapted to match the power supply circuit of the hand-free receiver to obtain the exact voltage supply value of the mobile telephone, which can be outputted to the power supply input leg of the mobile telephone to function as the power supply of the mobile telephone.

Abstract: A switching control device for transmitting calls received by a cellular phone to a fixed-network telephone enables people to receive calls transmitted to a cellular phone by way of a fixed network telephone particularly equipped with a plurality of extension lines via conversion operations. It operates with a cellular phone/fixed network telephone switching device in cooperation with an on/off device. When a cellular phone receives an incoming call, the switching device will first detect the main telephone set and its extension lines of their individual status of use; and the on/off device is selectively actuated of its on and off states and also its vibration ring operation according to the detection. Thereby a user can pick up a nearest extension line without rushing back to a main telephone set when an incoming call is transmitted to a cellular phone.

Abstract: A method for remote routes calculation and navigation with automatic route detection and revision couples with navigation data transmission of a navigation center to increase navigation accuracy and greatly reduce data transmission between the navigation center and navigation required users. The method mainly includes calculating a linear deviation limit to serve as the maximum allowance limit to alert timely response for route deviations to enhance navigation accuracy.

Abstract: A method for a vehicle dispatching system for controlling dispatching communications between vehicles and a control center mainly includes a control center and at least one vehicle. Every vehicle has equipped with a car phone. The control center includes a control computer and a data transmission device. The car phone consists of a broadcast receiver, a data transceiver, a GPS receiver, and a distance counter. By means of the method of the invention, the available vehicle nearest customers may be dispatched to meet customer service requirements at minimum communication costs.

Abstract: An improved car use computer and particularly to a computer adopted for use in a car has a screen panel which has a structure for adjusting the inclined angle of the screen panel. The structure mainly includes a casing, a medium storage and retrieval facility, an incline control means, a frame and a screen panel. Through the incline control means, the inclined angle of the screen panel may be adjusted to suit users' viewing requirements.

Abstract: A hand-free device equipped with expansion function modules allows a basic hand-free handset to attach expansion function modules depending on users' requirements so that the existing hand-free handset can be upgraded to equip additional or new function without obsolete. The invention consists of a hand-free main body and externally connected expansion function modules of various function desired. The function may be selected based on users' requirements such as GPS, PDA enabling, or audio control dialing, etc.

Abstract: A phone secretarial function extension device for a hand-free set is particularly related to one that is compatible with all available hand-free sets and cellular phones on markets and is equipped with phone secretarial functions (phone album, voice controlled actuation, voice dialing and recording/playing communication content). It mainly has a wired and wireless remote controller, a receiver and an I/O interface to cooperate with a cellular phone and its associated with hand-free set whereby all kinds of hand-free sets and cellular phones are able to perform extended functions such as a voice controlled dialing operation.

Abstract: A needle indicating navigation method, particularly relates to one using a monitor type display in combination with navigation equipment to transform navigational information into readable traveling routes messages on a screen of a display indicated by clock-like pointing needles for vehicle drivers. It mainly integrates into line connection the navigation equipment, wireless communication devices, navigation service centers or other information devices which can offer calculated traveling routes information whereby traveling route messages can be transmitted from a navigation service center or a self provided navigation program in a piece of navigation equipment to drivers on vehicles equipped with a display monitor, or by way of the connection of the information device and the navigation equipment to offer calculated traveling routes information.

Abstract: A wireless detachable conference telephone and particularly a conference telephone that has a plurality of wireless microphone seats detachable from a conference telephone main body.
