IPC: G06F12/06
Filed: 1988-02-11
Abstract: A data processing system includes a central processing unit (CPU), a main memory unit, and input/output (I/O) sockets, each adapted to receive a selected one of a plurality of different and/or similar option cards. Each card contains (or is connected to) and controls a respective peripheral device, and each card is pre-wired with an ID value corresponding to its card type. Programmable option registers on each card store parameters such as address information, priority levels, and other system resource parameters. A setup routine, during initial power-on, retrieves and stores the appropriate parameters in the I/O cards and also in socket locations in main memory, one location being assigned to each input/output socket. Each socket location is adapted to hold the parameters associated with the card inserted in its respective socket and the card ID value. That portion of main memory containing the socket locations is adapted to maintain the parameter and ID information by means of battery power when system power fails or is disconnected, i.e., a non-volatile memory portion. Subsequent power-on routines are simplified by merely transferring parameters from the memory to the card registers if the status of all the sockets has not changed since the last power-down.

Abstract: Computer Controlled Speakerphone for Adapting to a Communication Line Abstract A computer controlled speakerphone includes a line adapting arrangement for developing information about an interface between the speakerphone and a hybrid in a communication line and for providing optimal performance during operation by adapting operating parameters of the speakerphone to the line. During a conversation, the line adapting arrangement measures and averages the degree of hybrid reflection that is presented to the speakerphone. The hybrid reflection provides a measure of both the hybrid and a far-end acoustic return. By determining the degree of hybrid reflection, the switching threshold level of the speakerphone for switching between the transmit and the receive state may be adjusted. Once the expected level of receive speech due to hybrid reflection is known, additional receive speech due to the far-end talker may be accurately determined and the state of the speakerphone switched accordingly.  The amount of switched loss required in the transmit and receive speech paths of the speakerphone to maintain stability may be also be adjusted by the line adapting arrangement in accordance with the degree of hybrid reflection.  By lowering the amount of switched loss, speakerphone switching operation becomes more transparent and can even approach full-duplex for fully digital connections.

Title: Forward error correction code system
Inventor: MCAULEY ANTHONY JOSEPH
IPC: H04L1/22
Filed: 1991-02-25
Granted: 1997-09-30
Abstract: In accordance with an inventive Forward Error Correction (FEC) code, data is transmitted in codewords comprising n m-bit symbols. Of the n symbols, k symbols are known information symbols and h symbols are parity symbols for erasure correction. All of the symbols of the codeword are elements of a field of 2m integers which is closed with respect to addition and multiplication such as a Galois field. To determine the h parity symbols, an encoder circuit (17) derives a matrix corresponding to a set of simultaneous equations in terms of the k known information symbols and the h parity symbols. This set of equations is then solved for the h parity symbols so that a codeword is transmitted comprising k known information symbols and the h known parity symbols. At a decoder (19), the values of up to h erased symbols in the codeword may be reconstructed using a similar set of simultaneous equations.

Title: Ultraviolet absorbing green tinted glass
Inventor: GULOTTA JOSEPH A
IPC: C03C4/02
Filed: 1991-07-29
Granted: 1996-04-23
Abstract: A green tinted, ultraviolet absorbing glass is obtained by the addition of colorant to a standard soda-lime-silica base glass composition and a colorant includes less than 0.5 weight percent of cerium oxide (CeO2), greater than 0.85 weight percent of total iron expressed as Fe2O3 and a ratio of ferric iron expressed as FeO to total iron of less than 0.275.  The glass has a low ultraviolet transmittance, viz., no greater than 31 percent over the wavelength range of 300 to 390 nanometers at a reference glass thickness of 3.9 millimeters.  An advantage of the glass of this invention over competing ultraviolet absorbing glass is the use of larger amounts of total iron and smaller proportions of iron in the ferrous state to obtain the low ultraviolet transmittance.  In this manner, the amounts of cerium oxide which is expensive is reduced.

Abstract: An improved locking mechanism for detachably securing a seat back to a chair frame is disclosed. The improved locking mechanism includes a pair of side brackets secured to opposite sides of the seat back. Linkages supported from the chair frame are provided for receiving the slide brackets thereon for supporting the seat back on the chair frame in a predetermined orientation relative to the seat member. A moveable locking arm is supported from the slide brackets and includes an offsetarcuate cam surface which is adapted to engage an arcuate notch formed on the linkage when the locking arm is moved to a locked position. The mating engagement of the arcuate offset cam surface within the arcuate notch generates a line-of-contact therebetween which inhibits relative movement between the slide brackets and theupstanding links for rigidly securing seat member to the chair frame. An alternative embodiment discloses a modified link member which is adapted to create an interference engagement with the slide bracket to augment the locking action of the arcuate cam surface within the arcuate notch.

Each set of lugs includes long lugs in two sets, the first set extending axially inwardly greater than 45% to 60% of the section width. One long lug of the first set is circumferentially spaced between two other pairs of lugs of the first set. The second set of long lugs is similar and opposite in hand. The inner end of each long lug is spaced between inner ends of adjacent lugs of the opposite set. Circumferential spacing between each centerline of adjacent lugs is measured at a plane parallel to and located 75% of the distance from the equatorial plane to a plane tangent to the casing, at maximum section width. The distance differs by at least 10% of the section width from the spacing distance of each adjacent lug. There are two distinct circumferential spacings of lugs.
