Abstract: Disclosed is a musical tone signal generating apparatus for an electronic musical instrument. When waveforms of musical tones stared in PCM waveform memory (8) and generated from a tone generator (7) are switched to change a tone color in correspondence with a change in pitch by pitch designation switch section (5), waveforms are switched not simultaneously with a change in pitch but when waveform data corresponding to a loop end address is read out, and a value of the wave­form falls within a predetermined range or a zero-­crossing point is detected under the control of a CPU (1), thereby smoothly switching waveforms generated from the tone generator (7). The pitch is also changed at the above-mentioned timing to prevent generation of an unnecessary tone color upon switching. Furthermore, waveforms are switched by cross-fade control to more smoothly switch output waveforms.

Abstract: For reasons of environmental protection, ink ribbon cartridges have hinged lids in order to be able to exchange the ink ribbon spools after use. In this case, it is necessary to disengage the receiving spool mounted rotatably on a swivel lever from a drivable pin wheel. These rechargeable ink ribbon cartridges have the disadvantage that the ink ribbon can only be wound up without interference if the bearing axle for the receiving spool is arranged perpendicular to the bottom plate of the cartridge. If this is not the case, the ink ribbon is wound up in the form of a bale and the receiving spool on the bearing axle is displaced to the extent that the lid rises. These disadvantages are avoided according to the invention due to the fact that the core (28) of the receiving spool (27) is mounted on the bearing axle (25) with radial play and that the bearing axle (25) has at its free end a blocking projection (32) which is constructed radially on one side and against which a circumferential stop edge (32), which is arranged concentrically to the bearing bore (34) in the core (28) of the receiving spool (27), rests resiliently in the engaged position of the pin wheel (29) with the outer coil of the receiving spool (27) in such a way that displacement of the receiving spool (27) against the lid (5) is blocked when the excess radial play has been pressed out between the bearing axle (25) and the bearing bore (34). This reliably guarantees that the ink ribbon is wound up without interference even in the case of small variations in tolerance and inaccuracies in manufacture. <IMAGE>

Abstract: A videoconferencing system includes a plurality of videoconferencing sites (A to D), and a centralized video conference bridge. Each site receives an audio signal (from 122) including a superimposed control signal (from 114 to 117). The control signal designates all sites as passive, except for one site, which is designated as dominant and whose video signal is thereby broadcast to all other sites. During the videoconference, while the dominant site may change frequently, only one site at a time is designated as dominant. Thus, only one video channel is required, rather than a high speed video channel from each site to the VCB, as was required in prior arrangements.

Abstract: A device and related method for cryptographically processing data packets being forwarded in both directions between a communication network and a client interface, using only a single cryptographic engine, but without any degradation in latency or throughput performance, as compared with a device using two cryptographic engines. Outbound data packets received from the client interface are immediately parsed to determine if cryptographic processing is required, and an appropriate portion of each packet may be cryptographically processed as the packet is received and stored in an outbound buffer memory, until forwarded onto the communication network. Inbound data packets received from the communication network are not immediately parsed but are stored in an inbound buffer memory until the client interface is available. Parsing and any needed cryptographic processing of an inbound packet is not performed until the client interface becomes available and the packet is retrieved from the inbound buffer memory for forwarding. Since the client buffer cannot receive an inbound packet at the same time that it is sending an outbound packet, the single cryptographic engine serves to process traffic in both directions.
