Abstract: A hydraulic pump includes a casing, an impellor pump comprising a rotor that is rotationally mobile with respect to the casing about a first axis, the rotor comprising several blades in helix form, a transition zone belonging to the casing and having, on the side of the impellor pump, a ramp in helix form developing in the same direction as the helix form of the blades, a trochoid pump comprising a rotor with outer toothing secured to the rotor of the impellor pump, and a rotor with internal toothing that is rotationally mobile with respect to the casing about a second axis parallel to and offset from the first axis, the trochoid pump being fed by the impellor pump through the transition zone running along the ramp.

Abstract: The present invention concerns a wireless telecommunication terminal for a subscriber of a wide area telecommunication network, for example a Public Land Mobile Network, comprising a radio interface, at least one other alternative wireless communication interface and a data memory for storing subscriber specific profiles of applications and services. Terminal wherein said data memory contains particular data for enabling, managing and/or controlling the setting up and the upholding of a communication by means of the or at least one of the alternative wireless communication interface(s).

Abstract: It is proposed a solution enabling the use of a personal portable device over a network comprising terminals allowing a wireless communication with that device without implying each time a new awkward pairing with the terminals. This is achieved by allocating an unique address to a personalized profile. Said unique address will be used for a pairing procedure between a terminal of the network and a personal portable device. After a successful pairing, such initialization will be affected to said personalized profile. Latter will be used for future wireless communication between said personal portable device and a terminal. Advantageously, a pairing procedure will not be anymore necessary after performing once such initialization since for a set up of a wireless communication some parameters affected to the called personal profile will be used. Among other, the unique address allocated to said personalized profile will be assigned to said terminal.

Abstract: It is suggested to add some set of AT or Hayes commands for performing a wireless telecommunications between two terminals. This is advantageously adapted for controlling some mobile man machine interface among other when said wireless telecommunications will be supported over a Bluetooth radio link. It will then enable to support telephony over Bluetooth with very limited modifications in Serial Port Profile SPP. An implementation on PDA open platform is particularly easy.
