Title: Packet error indication method
Inventor: LOGSTON GARY L
IPC: H04L1/00
Filed: 1994-07-11
Abstract: A method for providing packet error indication (62) in a multi-hop  communications  system (10) in which packets (17) of data are transmitted from a transmission site (14) to a reception site (32) via a plurality of successive physical links (22a, 26a, 28a, 30a, 22b, 26b, 28b, 30b, 22c, 26c, 28c, 30c).  At  the transmission site, a pre-defined bit (62) in a packet (16) to be transmitted is set to a first value indicating that no errors are present in the packet. Then,  at each successive physical link, after transmission of the packet over that link, the following steps are performed: detecting (82) whether any uncorrectable errors occurred in the packet during transmission over that link; if an  uncorrectable error is detected, setting (90) the pre-defined bit in the packet to a second value indicative of an uncorrectable error in the data of the packet; and relaying (88) the packet to the next successive physical link for transmission over that next link.  A decoder (32) at the reception site may, upon receiving a given packet, examine the value of the pre-defined bit to determine the integrity of the data contained in that packet.

Abstract: An upsetting tool of a pair of upsetting tools for the deformation of continuously cast slabs in a slab upsetting press is composed of two connecting rods which are driven through two eccentric shafts and which support the upsetting tool and guide the upsetting tool in parallel direction. Hinged to the connecting rods is a piston/cylinder unit for producing a movement of the upsetting tool synchronously with the slab movement on a roller table. The upsetting tool has upsetting surfaces for acting on one of the two longitudinal sides of the slab. The upsetting surfaces extend parallel or inclined relative to the direction of movement of the slab. The upsetting surfaces are located next to one another so as to form edges extending transversely of the direction of movement of the slab, wherein upsetting surfaces inclined away from the longitudinal side surfaces of the slab are arranged following or possibly in front of an upsetting surface extending parallel to the travel direction of the slab. Each upsetting tool has a first inclined upsetting surface and one or more additional upsetting surfaces with angles of inclination which are smaller than the angle of inclination of the first upsetting surface.

Title: DC Circuit Breaking Device
Inventor: ITO HIROKI
IPC: H01H33/59
Filed: 1996-08-07
Abstract: A DC circuit breaking device is provided for interrupting the transmission of direct currents to an electric power system by making external changes to an arc generated upon contacting or separation of contacts in order to rapidly extend and vibrate arc currents. In a self-excited commuting DC circuit breaking device, coils opposed to a fixed and a movable contact are disposed around the outer circumferences of the contacts, and currents flowing through a commutation circuit or the contacts are allowed to flow through the opposed coils so as to apply magnetic fields to the neighborhood of an arc.      This constitution provides the DC circuit breaking device with high performance that it can rapidly extend and vibrate arc currents to thereby interrupt direct currents.

Inventor: HOLLIER MICHAEL PETER
IPC: H04B3/46
Filed: 1995-08-17
Abstract: A method of analysis of characteristics of a telecommunications network by measuring properties of speech carried by a line under test comprises the steps of identifying a part of the speech signal which has a property independent of the talker, and detecting deviations from that property in the received signal, thereby identifying characteristics of the signal imposed by the system. The properties identified may be characteristic waveforms of speech phonemes, in which the fact that the human voice is only capable of making certain sounds is used to determine what deviations from those sounds have been imposed by the system. In an alternative arrangement identifying a part of the speech signal having a property which varies in a predetermined manner in relation to an absolute characteristic of the talker, and deriving the absolute characteristics therefrom. The absolute characteristic may be the absolute level of the voice, and the other property may be a talker-independent function of the absolute level, such as the spectral content of the unvoiced fricatives in the speech.

Title: Methods and apparatus for encoding and decoding data transmitted over telephone lines
Inventor: KELLY MICHAEL K
IPC: H04M11/06
Filed: 1995-10-04
Abstract: A method of generation and detection of acoustic signals carrying alpha-numeric data for reducing the effects of noise and thereby improving signal transmission without the need to boost the power of the signal. In accordance with one aspect of the invention, a special DTMF acoustic signal consisting of a combination of two frequencies will be generated for the representation of a particular alpha-numeric character that will be similar to the standard DTMF  tone. The difference between the amplitudes of both frequencies varies during the time of generation of the DTMF tone in such a way that both signals will arrive at a final destination detector, i.e., an interactive voice response board, at least for a portion of the generation time, at a relatively similar amplitude, thereby substantially increasing the probabilities of being recognized as a DTMF signal.

Abstract: An aircraft display combines speed error tapes and multiple speed reference bugs to produce a display which reduces pilot workload . The length of the speed error tape is indicative of the difference between a current aircraft speed and a reference speed. Multiple reference bugs are adjacent to the error tape and are indicative of the difference between the current aircraft speed and other selected reference speeds. The reference bugs move along the error tape thereby communicating the status of the current aircraft speed relative to the multiple reference speeds. The display reduces the need for the pilot to scan and analyze numerous instruments for the same information.
