Abstract: A railway freight brake system for operating vehicles in a train wherein each vehicle responds in braking situations as if its effective net braking ratio was a desired train net braking ratio. Embodiments include vehicles receiving a brake signal and utilizing either a received train net braking ratio or utilizing a stored on-board train net braking ratio to control pneumatic equipment on-board the vehicle to produce brake forces on the vehicle generally corresponding to the net braking ratio of the train. Some embodiments use a common train line control to communicate both train net braking ratio and brake signals to the individual vehicle. Individual vehicles can receive periodic or initial train net brake ratio values.

Abstract: A socket drive adapter for retrofitting to a solid hub earth anchor to convert the solid hub earth anchor into a socket drive earth anchor. The socket drive adapter is formed from a trapezoidally shaped steel plate by a series of 90°  bends. The bends create square, bore-defining adapter that can be welded to the top surface of the helical blade around the solid hub. A drive wrench fits in the socket drive adapter and engages both the socket drive adapter and the solid hub to enhance the torque strength of the anchor while retaining the better ground penetrating aspects of the solid hub design.

Title: Digital signature protocol
Inventor: VANSTONE SCOTT A
IPC: H04L9/32
Filed: 1997-10-10
Granted: 2007-07-17
Abstract: A digital signature protocol generates a signature component using a hash of an encrypted message. The component and encrypted message form a signature pair that is forwarded to a recipient. The encryption message is used to retrieve the encryption key at the recipient and authenticate information in the message. The signature pair may be applied to a data carrier as a bar code for use in mail delivery services. By utilizing a hash of the message, a reduced message length is achieved as individual signatures are not required for each component of the message.

Abstract: In a speech signal coder according to the present invention, spectral or pitch parameters of a speech signal are quantized, and impulse responses thereof are predicted by using a filter constituted thereby. An orthogonal transform of the speech signal or a signal derived therefrom or the impulse responses or signals derived therefrom is obtained, and the result is entirely or partly quantized to obtain a plurality of pulses. More preferably, these pulses are retrieved recurrently by also using codevectors retrieved from a codebook or collectively quantizing their senses or amplitudes. Optimization is achieved in this way.

Abstract: The present invention relates to a method and apparatus for cancelling an echo in a system, in order to improve the quality of sound significantly.      Switch (141) continuously switches between received signal and a supplemental signal, which is obtained by processing the received signal (2) through filter (145). Accordingly, adaptive filters (122) and (124) operate sometimes by using received signal (2) as the input signal and sometimes by using the supplemental signal as the input signal, so that it is possible to obtain adaptive filter coefficients by using twice the number of conditional equations as the case of using only received signal (2) as the input signal. As the adaptive filter coefficients do not become indefinite, it is possible to converge the coefficients to the correct values. Further, by making the switching period between the original and the supplemental signals to be longer than the sampling period of the received signal, it is possible to suppress aliasing distortion of the received signal directly supplied to a speaker and to maintain better sound quality.
