Title: Liquid membrane modules with minimal effective membrane thickness and methods of making the same
Inventor: PRASAD RAVI
IPC: B01D63/02
Filed: 1992-04-13
Abstract: ABSTRACT Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness.  The modules have a module case and at least one pair of superposed fabric sheets disposed within the case, the fabric sheets being pleated and nested in the lengthwise direction of the case.  Each fabric sheet contains warp-wise extending hollow fiber membrane. The hollow fiber membranes within the folds of one fabric sheet will therefore form alternating rows with the hollow fiber membranes within the folds of the other fabric sheet by virtue of the length-wise nested pleating.  As a result, the effective membrane thickness value of the module is minimized thereby enhancing the efficacy of fluid separations.

Patent CA-2087809-A1 (CA)
Inventor: DOAN DAVID B
IPC: A61M5/00
Filed: 1993-01-21
Abstract: A compliant chamber is formed in a fluid line which connects a fluid supply to a fluid receiver. The compliant chamber is alternately in fluid communication with the upstream and downstream segments of the fluid line. When the chamber communicates with the upstream segment it receives and stores fluid at the head pressure. When the segment communicates with the downstream segment, a pressure equalization pulse occurs. A pressure sensor in the downstream segment measures the pressure equalization pulse which is proportional to the head pressure. Processing the equalization pulse with the downstream fluid system resistance, the compliance of the compliant chamber and the equilibrium pressure results in a determination of the head pressure. Comparing the head pressure to thresholds permits determination of an occlusion or empty fluid supply. Where a peristaltic pump is used, the chamber is formed between the end fingers of the pump.

Patent CA-2100101-A1 (CA)
Inventor: YOSHIMURA SHUJI
IPC: H04L12/70
Filed: 1993-07-08
Abstract: A first terminal unit is connected to a line switch via a set of data lines. A second terminal unit is connected to the first terminal unit via a set of data lines. A third terminal unit is connected to the second terminal unit via a set of data lines. Therefore, the terminals are sequentially connected in series. Cells transmitted to the terminals are multiplexed by each terminal and sequentially transmitted upstream, to the third terminal unit, the second terminal unit, and the first terminal unit together with a token.      Since the first terminal unit receives a first identification signal from a switch and a second identification signal from downstream, the first terminal unit recognizes that it is the highest order terminal unit, and sends a cell to the switch after separating the cell from a token which is to be returned downstream. Since the second terminal unit does not receive the first identification signal and receives only the second identification signal, it recognizes that it is an intermediate terminal unit, and sends back downstream a token returned from upstream. Since the third terminal unit does not receive the identification signals, it recognizes that it is the lowest order terminal unit, and sends upstream a cell transmitted via a low data rate line according to a token returned from upstream.

Title: Method for remotely overriding of program or file access passwords from a telephone instrument
Inventor: GALLICK ROBERT L
IPC: G06F12/14
Filed: 1993-07-15
Abstract: A METHOD FOR REMOTELY OVERRIDING OF PROGRAM OR FILE          ACCESS PASSWORDS FROM A TELEPHONE                       ABSTRACT A method of overriding a file or program access password from a remote location via a telephone inter-face.  The password is used by a computer program to either lock the program or one of its data files.  Also, the computer program contains a master override code to which the received override code must match.  A regular DTMF telephone and telephone line are used.  The first step requires that a connection be established between the computer and the telephone.  This can be accomplished by either having the computer user call the remote tele-phone, or the remote telephone call the computer user. After the connection is established, the computer user is asked to place the computer in the proper mode.  Gener-ally, this requires that the computer user place the com-puter program in the mode where it is expecting the com-puter user to enter the password.  Next, DTMF tones rep-resenting the override code are transmitted from the telephone to the computer.  After receiving the tones, the computer converts the received tones to the override code and compares it to the master override code. Finally, the password is modified if the override code matches the master override code.

Patent CA-2106919-A1 (CA)
Inventor: OSHIMA MITSUAKI
IPC: H04N7/00
Filed: 1993-09-24
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.
