Title: Moment-resistant structure, sustainer, and method of construction
Inventor: ASCHHEIM MARK AMOS
IPC: E04H9/02
Filed: 1998-02-03
Abstract: The present invention relates to a moment-resistant structure, sustainer (3), and method of construction for deformably resisting episodic loads and may be utilized in new construction and in rehabilitation of existing construction.  Deformation capacity is enhanced by the use of multiple dissipative zones which function in a manner similar to plastic hinges and which are detemined by one or more voids (6a-6f) that are located in the web (4) of a sustainer (3). The voids are of a size, shape, and configuration to assure that the dissipative zones deform inelastically when a critical stress is reached, thereby developing the action of a structural fuse, preventing the occurrence of stress and strain demands sufficient to cause fracture of the connection welds or adjacent heat-affected zones. The sustainers may be removably connected to the remainder of the structure, facilitating replacement after inelastic deformation. Mechanical equipment and utilities may pass through the voids.

IPC: H04M3/42
Filed: 1998-12-23
Abstract: Telecommunications switches (S1-Sn, 3) route calls in accordance with economic incentives (e.g., least cost routing) resulting from an auction process between participating telecommunications carriers (C1-Cn, 2) by operation of a central moderator processor (1). Each of the carriers (C1-Cn, 2) informs the moderator (1) of the rate it is willing to charge for service at a particular time between two switching points defining a route segment. The moderator (1) collects bid information from all the carriers (C1-Cn, 2) processing the bid information, transmits bid information to participating carriers' (C1-Cn, 2), network management centers, and transmits carrier selection data to the subscribing switches (S1-Sn-3). The carriers (C1-Cn, 2) may change their bids as often as they like. A subscribing switch (S1-Sn, 3) can route traffic to those carriers (C1-Cn, 2) offering the best economic incentives and can change such routing decisions at any time.

IPC: G09C1/00
Filed: 2000-02-10
Abstract: The invention concerns an on-board system for verifying a certification request of a public key (Kp) generated by an on-board identifier system (SNi). For an assembly (Lk) of on-board systems, an authorised identifier (OPj) operator configures the on-board systems and generates (1001) a parent public key (KpM) and a parent private key (KsM). The identifier (Opj), the reference range of identifiers (Lk) and the public key (KpM) are issued (1002). For each on-board system (SNi), a diversified key (KsMi) is generated from the identifier (SNi) and stored (1003) in a storage unit with protected reading and writing access. For every public key (Kp) generated by an on-board system, a cryptographic control value (Sci) is computed (1006) on the public key (Kp), an algorithm identifier (CA1) and utilisation parameters (U) of said key using a zero-knowledge signature algorithm and a certification request message (MRCA) including the control value (Sci), the operator identifier (Opj) and the identifier (SNi) is transmitted to a certification authority, which retrieves the identifier (Opj) (1009) and the parent public key (KpM) value (1001). Verification (1012) of the message (MRCA) from the parent public key (KpM) and of the identifier of the on-board system (SNi) enables to ensure that the public key (Kp) certification request and the use thereof originates indeed from an on-board component capable of restricting the use of said key.

Abstract: The amount of high molecular weight impurity present in a polyether polyol produced by alkoxylation of an active hydrogen-containing initiator and a substantially noncrystalline highly active double metal cyanide complex catalyst may be advantageously lowered by treating the catalyst prior to use in polymerization with a protic acid. Suitable protic acids include phosphoric acid and acetic acid. The higher purity polyether polyols thereby produced are particularly useful in the preparation of slab and molded polyurethane foams, which tend to collapse or become excessively tight when elevated levels of high molecular tail are present in the polyether polyol.

Abstract: A source signal (e.g. a voice test) is processed by a voice coder or transmitted and converted into a receive signal (coded voice signal). The source and receive signals are separately subjected to preprocessing and to psycho-acoustic modeling, followed by internal calculation to evaluate the similarity of the signals. Finally, MOS calculation is carried out to obtain a result that can be compared with human evaluation. According to the invention, a spectral similarity value is determined for evaluating transmission quality, which is based on calculating the covariance of the spectra source and receive signals and dividing the covariance by the standard deviation of the above mentioned spectra. The inventive method enables objective evaluation (voice quality forecast) while taking into account the human hearing process.

Abstract: A heterogeneous telecommunications system employs "out of band" signalling to automatically discover the identity of the two ports connecting two network elements through a specific link. Either of the connected network elements may be a circuit switching network element or a packet switching network element. One network element initiates the port discovery process and transmits an overhead signal, such as a SONET/SDH protection switching message, to the network element attached at the other end of the link. The other network element monitors the status of its ports and, when it detects a change in state at one of the ports, resulting from the first network element's transmissions, the receiving, or passive, network element recognizes the port as the port which forms a part of the link of interest.  Each group of network elements, packet switching and circuit switching, elects a network element leader which coordinates requests for port identification.

Abstract: In a seedling-interval regulation apparatus, the transport interval between two adjacent seedlings successively transported by a variable speed conveyer is calculated by measuring a distance over which the preceding seedling is transported between a point in time when the preceding seedling is detected by a seedling sensor and a point in time when the succeeding seedling is detected by the seedling sensor. The calculated transport interval between the seedlings is compared with the planting interval. When the calculated transport interval coincides with the planting interval, the transport speed of the variable speed conveyer is maintained. When the calculated transport interval does not coincide with the planting interval, the transport speed of the variable speed conveyer is increased or decreased or the variable speed conveyer is stopped, such that the transport interval between two adjacent seedlings becomes equal to the planting interval immediately after the preceding seedling is discharged from the variable speed conveyer.

Abstract: An initial charging operation is carried out by a charging step composed of two-stages or more to improve an initial charging and discharging efficiency, reduce the charge of wasteful materials and improve a high capacity and a high cyclic characteristic without deteriorating various kinds of battery properties. In order to realize the improvements, a nonaqueous solvent which is decomposed under a potential higher than the reduction and decomposition potential of a main solvent is included in electrolyte. This charging method is a method for achieving the addition effect of such a nonaqueous solvent as much as possible. As a specific means, the electrolyte to which vinylene carbonate is added is employed and a constant-current and constant-voltage charge under about 3.2 V is carried out for 1 to 2 hours before a battery is completely charged. Thus, a good coat can be formed on the surface of an anode while suppressing the quantity of electricity required for forming the coat.
