Title: Processo para controlar a potência de transmissão de uma estação base, de duas ou mais estações base e de dois ou mais setores de uma estação base para uma estação móvel, em um sistema de comunicações móveis e estação base para comunicar com uma estação móvel
Inventor: BUTOVITSCH PETER
IPC: H04B7/005
Filed: 1999-03-26
Abstract: "PROCESSO PARA CONTROLAR A POTêNCIA DE TRANSMISSãO DE UMA ESTAçãO BASE, DE DUAS OU MAIS ESTAçõES BASE E DE DOIS OU MAIS SETORES DE UMA ESTAçãO BASE PARA UMA ESTAçãO MóVEL, EM UM SISTEMA DE COMUNICAçõES MóVEIS E ESTAçãO BASE PARA COMUNICAR COM UMA ESTAçãO MóVEL". A potência de transmissão de uma transmissão de estação base para uma estação móvel é vantajosamente controlada. A estação base recebe um sinal da estação móvel e determina uma relação sinal interferência (SIR) associada ao sinal recebido. A estação base controla sua potência de transmissão para a estação móvel, usando o valor SIR determinado em conjunto com um comando de controle de potência de transmissão recebido da estação móvel. Quando a estação móvel está no processo de uma transferência de passagem suave envolvendo duas ou mais estações base, cada uma daquelas estações base determina um valor SIR associado a um sinal recebido da estação móvel. Ainda mais, cada uma das estações base controla sua respectiva potência usando ambos comando de controle de potência recebido da estação móvel e SIR determinada por aquela estação base. Similarmente, quando a estação móvel está no processo de transferência de passagem mais suave envolvendo dois ou mais setores de uma única estação base, a SIR associada a um sinal recebido da estação móvel em cada um daqueles setores de estação base é determinada e usada para controlar a respectiva potência de cada setor de estação base, em conjunto com um comando de controle de potência recebido da estação móvel.

Title: Automatic tennis ball projector - has a hopper ball feed and a centrifugal lock disc
IPC: A63B69/40
Filed: 1972-10-27
Abstract: The projector consists of two circular end plates separated by a spirally curved panel to form a drum (18) which is rotated about a horizontal axis. The ball hopper is positioned at one side with an inlet hole (13) into the drum near the centre. A light circular disc (9) rotates about its own central axis which is parallel to but displaced from the drum axis. The disc centre of gravity lies radially displaced from its centre of rotation (8). A curved cutout large enough to accommodate a ball is cut from the disc periphery diagonally opposite to the centre of gravity. When no ball is in the drum the cutout is opposite the inlet hole. With a ball in the drum and in the cutout, centrifugal force rotates the disc to close the inlet.

Title: Error detection coding between a transcoder rate adaptor (TRAU) and base transceiver station (BTS)
Inventor: PIERCY NEIL
IPC: H04W88/18
Filed: 2001-04-18
Abstract: A cellular radio telecommunication system comprising a Basestation Transceiver System BTS and Transcoder Rate Adaptor TRAU in which the TRAU implements pre-coding of Enhanced Full-Rate EFR speech data for error checking at the Mobile Station MS. The BTS and TRAU may be co-located, or separated by a transmission link which has very low error rates. Error detection bits in the TRAU frame carrying Enhanced Full Rate EFR speech data may conform to a predetermined pattern which is recognised by the BTS and ignored for error correction. These error detection bits may be used across the BTS-TRAU interface for error checking of all the speech data bits of the TRAU frame evenly. The TRAU and BTS may negotiate the error checking protocol to be used so that this conforms to that used by the BTS.

Title: An automated recognition system
Inventor: MURPHY ANDREW JOHN
IPC: H04H20/28
Filed: 2001-05-14
Abstract: An automated recognition system is used to recognise an audio cue, such as a piece of music or 'jingle', and to generate useful ancillary data therefrom. The cue identifier 10 has a library 12 storing information about different audio cues. A received signal is applied to an ADC 20 which samples overlapping windows of about the expected jingle length eg 2 secs. A frame generator 24 generates for each window a plurality of overlapping frames which are fed to an FFT processor 26 to estimate the frequency content of the frames. This data is filtered 28, the logarithm taken 30, and applied to a matrix generator 32. A processor 34 forms a covariance matrix which is compared with those in the library 12. The system may be used in a network or transmitter station (Fig. 3) to add a data signal to the signal, or at a receiver (Fig. 4) to control a recorder. The system can be used with TV rather than radio broadcasting.
