Abstract: A video game apparatus includes an RCP. The RCP performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The RCP detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the RCP selects the non-player object as an attention non- player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.

Title: Manufacture of unidirectional fibre reinforced thermoplastics
Inventor: KAUFMANN STEFAN
IPC: B29B13/02
Filed: 1998-12-14
Granted: 2004-04-20
Abstract: The method for the manufacture of unidirectionally fibre reinforced thermoplastic bands (1) comprises a pressure impregnation of a fibre strand (1') in a bath (3) with a dispersion (22) of thermoplastic particles. Heat treatments (5, 6) for the drying of the strand (1") and a melting on of the particles taken up by the strand follow the pressure impregnation. The strand is drawn through the bath at a predetermined draw-off speed (v) about a plurality of deflection elements (4). The dispersion (22) of the bath is largely held in a stationary state, namely through the supply of an infeed dispersion (21) with a first particle concentration (c1) and through an initial setting of a second particle concentration (c2) in the bath: The infeed dispersion is fed in continuously or periodically, with the first particle concentration being held constant. A corresponding feeding in of a dispersion of higher particle concentrations as well as an additional amount of dispersing medium (210) is possible. The second particle concentration is set to a value which remains constant through an automatic self-setting alone. In this the two named concentrations (c1, c2) depend in an empirically determinable manner on a thermoplastic content (.theta.) of the band (1) to be achieved and on the draw-off speed (v).

Abstract: In a broadband network comprising a plurality of edge switches interconnecte d by a plurality of tandem switches, IP packet data is routed by determining from each packet whether that packet forms part of a flow of packets. Where a packet is determined to be part of a flow, it is segmented into minicells for transmission over a permanent virtu al channel established across the network for that flow. Where a packet is not determined to be part of a flow, a destination edge switch i s identified for that packet which is then transported to that edge switch via a default permanent virtual channel. Permanent virtual channels for new flows are established at the network periphery by defining a succession of nodes and virtual channels (VCs) to be used to reac h the destination of that flow.

Title: A coherent combining/noncoherent detection (ccnd) method and apparatus for detecting a pilot signal in a wireless communication system
Inventor: XIAO-AN WANG
IPC: H04B1/7117
Filed: 1999-09-17
Granted: 2007-07-31
Abstract: A method and apparatus are disclosed for detecting a pilot signal in a wireless receiver using coherent combining/noncoherent detection (CCND) techniques. Coherent combining/noncoherent detection (CCND) techniques are used to detect the pilot signal whenever the receiver is already frequency locked, or otherwise known to have a small frequency offset. Conventional noncoherent combining/noncoherent detection (NCND) techniques are utilized to initially acquire the timing of the forward channel. Once the receiver is frequency locked, coherent combining/noncoherent detection (CCND) techniques may be used to continuously detect the pilot signals. After the receiver is frequency locked, the residue frequency error is small over several consecutive correlator outputs. The correlator outputs can thus be combined coherently (since the frequency error is known to be small), and the phase dependency is then eliminated by noncoherent detection. The disclosed coherent combining/noncoherent detection (CCND) technique can be extended to the case where the accumulation length, L, is too large such that coherent combining over L correlator outputs will have significant degradation even when the frequency error is small. In this case, the L outputs can be broken into M groups each of which contain L1 outputs, such that L = ML1.
