Title: Method and apparatus for performing local traffic measurements in a cellular telephone network
Inventor: JOHANSSON AKE
IPC: H04W16/18
Filed: 1998-03-10
Abstract: A method and apparatus for measuring telephone traffic volume in a cellular telephone system (100) is disclosed. In a first embodiment, a receiver (150) is located at the proposed micro-cell site (120) and measures the strength of signals transmitted by mobile stations (130) to determine the cellular telephone traffic in the proposed micro-cell site (120). In a second embodiment of the present invention, a test base station (500) is located at the proposed micro-cell site (120). A processor (510), communicating with the base station controller (300) serving the macro-cell (110) surrounding the proposed micro-cell site (120), extracts signal strength measurement reports transmitted to the cellular telephone network (100) from mobile stations (130) in and around the proposed micro-cell site (120). The processor (510) uses the signal strength measurements to calculate the cellular telephone traffic volume in the proposed micro-cell site (120). In a third embodiment of the present invention, a test base station (700) is located at the proposed micro-cell site (120) and is assigned a location area identity different from that of the macro-cells (110) surrounding the proposed micro-cell (120). Mobile stations (130) operating in and around the proposed micro-cell site (120) are required to register in the new location area and transmit a signal strength report which includes the signal strength of the test base station (700). A  processor (710) connected to the test base station (700) uses the received signal strength reports to calculate cellular telephone traffic volume in the proposed micro-cell site (120).

Abstract: Une quantité prédéterminée de boue résiduelle de papeterie est déchargée en continu d'un réservoir de stockage sur un mélangeur/transporteur pour créer un premier flux réactif. Une quantité prédéterminée d'oxyde de calcium est introduite dans ce premier flux réactif à partir d'un réservoir d'oxyde de calcium. L'oxyde de calcium et les boues résiduelles sont mélangés pendant qu'ils se déplacent dans le mélangeur/transporteur, pour former un premier mélange intermédiaire. Après l'écoulement d'une durée suffisante pour permettre la réaction de l'oxyde de calcium et des boues résiduelles, une quantité prédéterminée de diatomite est ajoutée au flux réactif à partir d'un réservoir de diatomite. Le premier flux réactif, désormais composé du premier mélange intermédiaire de boues résiduelles et d'oxyde de calcium combiné à la diatomite, constitue un produit utile, sans danger pour l'environnement.

Patent CA-2307240-A1 (CA)
Title: Matchline sense circuit and method
Inventor: AHMED ABDULLAH
IPC: G11C7/06
Filed: 2000-05-01
Abstract: A matchline sense circuit for detecting a rising voltage on a matchline of a CAM array is disclosed. The circuit initially precharges a matchline to ground before turning on a current source to supply current to the matchline and raise the voltage of the matchline. A reference matchline sense circuit generates a self-timed control signal to keep the current supply turned on for a predetermined duration of time. Sensed data on the matchlines are latched after the current source is turned off and the matchlines are precharged to ground. Because the matchline sense circuit of the present invention precharges the matchlines to ground instead of the supply voltage, VDD, less power is consumed. By sensing the rise of the matchline voltage to an n-channel transistor threshold potential, the matchline sensing operation speed is increased.

Title: Method and apparatus for receiving radio signals
Inventor: ANDERSSON SOREN
IPC: H01Q3/24
Filed: 1998-10-30
Abstract: The present invention relates to radio systems and, more particularly, to a method and apparatus for receiving radio signals with the aid of beams generated by antenna assemblies. For each of the beams in a first of the antenna assemblies there is a beam in the second of the antenna assemblies that covers the same space area. Signals received by the second are delayed relative to signals received by the first of the antenna assemblies. Then signals from the first antenna assembly are combined with signals from the second of the antenna assemblies. The combined signals derive from beams covering the same space area. Each combined signal is then radio received in a joint radio receiver. A DOA-estimation can be calculated on the basis of radio received signals derived from all beams.
