Patent CA-2170628-A1 (CA)
Inventor: LAZARIDIS MIHAL
IPC: H04M11/06
Filed: 1994-08-29
Abstract: The present invention provides a method for enhancing service signals transmitted by a DCE, such as a Modem, to a DTE user.  Since any transmission from a remote computer to a DTE user through a wireless communication network can be encoded   with additional  information,    use of an AT compatible   modem in conjunction  with a  wireless communication  network  adds a new   dimension  of  information that can be displayed to the DTE user. The present invention also includes a method for ensuring effective data transfer from a DCE to a DTE user.   When  a DTE receives a connection  service signal it will often require several internal adjustments before it can accept data. Because data received by a radio-based modem is received in packets, under certain conditions data will be waiting to be transmitted to the user immediately after the modem enters a data transfer state. The method of this invention includes the steps of transmitting a service signal to the DTE indicating that the modem has entered a data transfer state and delaying for a predetermined time after transmitting the data-transfer-state signal before transmitting data from the modem to the DTE.

Inventor: HANSEN EJNER BJ RN
IPC: A47J37/04
Filed: 1994-11-15
Abstract: An apparatus (1) for use in heat treatment of for example French fried potatoes (10). This process takes place in a treatment chamber (3) where the product is exposed to intensive heat radiation from a number of quartz tubes (14) while they constantly are tubed by means of a rotating driving wheel (15) with a number of carriers (16) placed along the periphery. Humidity, smoke and smell separated from the product during this process are sucked off by means of a ventilator (17) which leads the polluted air through a filter device (4) via a convector (5) between the treatment chamber (3) and the filter device (4). The whole arrangement is built up into a cabinet (2) which on the top and at the bottom is provided with ventilation openings (26, 27) through which secondary air is flowing for cooling the polluted air flowing through the convector (5). Thereby a heat exchange effect is obtained for reducing the sucked off temperature to an acceptable level before the air reaches the filter device (4). The apparatus has a construction which is compact and environmentally compatible and suitable for preparing for example pre-fried potato pieces into ready French fried potatoes with very low contents of fat.

Title: Data transmission system, data recording and reproducing apparatus and recording medium each having data structure of error correcting code
Inventor: TANAKA SHIN-ICHI
IPC: H03M13/29
Filed: 1996-04-01
Abstract: A data transmission system for transmitting information data with a parity of an error correcting code for correcting an error in the information data. A  read--out controller controls a transmitter to transmit the data and the parity so that each data component of the data obtained by dividing the data of one data block area into a plurality of data components and each parity component of the parity obtained by dividing the parity of one block area into a plurality of parity components are transmitted at intervals of each sector having a sector address. The sector is defined as a data area obtained by dividing one data block area of a predetermined data amount into a plurality of sectors each having an identical data amount.  Since the parity is not recorded in a bunched continuous area but rather dispersed throughout the sector, the information data can be regularly read thereby simplifying that data reproducing and the read-out apparatus.

Title: Control of telecommunications networks
Inventor: ANDERSON THOMAS WAYNE
IPC: H04Q11/04
Filed: 1997-01-20
Abstract: Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network.  The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network.  SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor.  The call processor communicates with one or more switching processor means for controlling establishment of the call.  Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection.  Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.
