Title: Wireless terminal data network communication
Inventor: FISHER BRADLEY J
IPC: H04L12/56
Filed: 1997-05-23
Abstract: A gateway computer is connected to a wireless station switch which receives  and sends  transaction processing  data  between  remote  terminals  and  a transaction processing host.   The gateway interprets an exception code in the data packet received from the terminals to determine whether data is to be forwarded or whether a predetermined circuit management activity is to be carried out by the gateway for the purposes of  call  request,   call  accepting, acknowledging, negative  acknowledging,  call  clear  requesting,  call clear  confirming  or  call  reset  confirming.    The terminals make use of the exception code to make it easier for the gateway to either pass on data or carry out  the  predetermined  circuit  management  activity while reducing both the amount of interpretation and processing required by the gateway and reducing over-the-air traffic between the terminals and the wireless station.

Patent CA-2213611-A1 (CA)
Inventor: JOHANSSON TED
IPC: H01L29/73
Filed: 1996-02-16
Abstract: La présente invention concerne un dispositif et un procédé permettant de contourner les résistances de protection de l'émetteur d'un transistor de puissance, ce qui augmente son gain. Dans le cas d'un transistor de puissance du type interdigité, le contournement des résistances de protection de l'émetteur exige le contournement de chaque résistance de protection au moyen d'un condensateur monté en parallèle. C'est pourquoi le contournement se fait sur la puce de silicium. Plus particulièrement, selon un mode de réalisation de l'invention, un transistor de puissance HF comprend une puce de silicium, une résistance (13) de protection de l'émetteur formée sur la puce de silicium et un condensateur de contournement (40) formé sur la puce de silicium et relié en parallèle à la résistance (13) de protection de l'émetteur. La résistance peut être réalisée par diffusion et le condensateur peut être un condensateur du type métal sur polysilicium. Selon un autre mode de réalisation de l'invention, on met en oeuvre un procédé visant à augmenter le gain d'un transistor HF formé sur une puce de silicium et ayant une résistance de protection de l'émetteur également formée sur la puce de silicium, ce transistor comportant un condensateur formé sur la puce de silicium et relié en parallèle à la résistance de protection.

IPC: A61M25/00
Filed: 1997-09-17
Abstract: A process for forming the tips on catheters is described in which the catheter is placed on a mandrel and molded in a mold. The mandrel may then be removed and a second mandrel inserted. The second mandrel having a larger diameter and adapted to contact inner surface of the mold to thereby cut any flash formed at the end of the catheter and separate the flash from the catheter tip.     Alternatively, the mandrel and catheter are inserted into the mold to mold the outer surface of the catheter thereafter removed and inserted into a die to punch the flash from the tip of the catheter material. The punch process may be carried out by either the same mandrel or a second mandrel adapted to the purpose of cutting or punching the flash from the catheter.

Title: A tubular calibration unit for machines for extruding plastic strings such as pipes
Inventor: PEDERSEN KNUD KRISTIAN
IPC: B29C48/90
Filed: 1996-05-17
Abstract: For calibration and stabilisation of the discharge product from extruders it is known to use tubular calibration units both for calibration of the product diameter and for cooling of the product for initial stabilisation of the product, whereby the calibration pipe should have a noticeable length. For a current exact calibration it may be desirable to effect small changes of the calibration diameter, yet with associated problems in exchanging the calibration pipe. The invention provides for a calibration pipe (14) with adjustable diameter, viz, in that the pipe is made of a number of split rings (16), which are juxtaposed with random locations of the splits (18), such that the pipe when seen in its axial direction is entirely unbroken. The rings (16) may be collectively radially compressed in a controlled manner by means of axially extending wedge clamp rods (24, 26) for a uniform adjustment of the diameter of the pipe (14} as a whole.

Title: Telephone system integrating a public switched telephone network, a packet-switched network and a call answering system
Inventor: PICARD DONALD F
IPC: H04M3/428
Filed: 1998-01-29
Abstract: The present invention is directed to a system that allows a subscriber to take a telephone call over the Internet when the subscriber telephone line is busy servicing a browser-based Internet session without requiring that the subscriber disconnect or terminate the Internet session.  The system transfers a telephone call to a subscriber telephone line that is busy to a call servicing platform where the platform determines if the subscriber line is busy due to an interactive Internet session.  When a session is in progress, the platform informs the subscriber via a network message to the subscriber's personal computer involved in the session that a call is waiting.  If the subscriber accepts the call, the platform digitizes the speech of the caller and sends it to the computer where it is output to the subscriber.  At the same time, the computer digitizes the speech of the subscriber and sends it to the platform, where it is output to the caller.  The system can also allow the subscriber to screen the caller by listening to the caller as a message is recorded.  The network session can continue during the transfer of the speech or resume after the call is finished, that is, the session need not be terminated to free the telephone line to carry the call.
Patent CA-2228594-A1 (CA)
Title: Method of sorting pieces of material
Inventor: GESING ADAM J
IPC: B07C5/36
Filed: 1996-07-31
Abstract: A method (95, 195, 300) of sequentially sorting pieces of material (Pi) in real-time into output bins (10, 12, 14) where each piece has a composition defined by a plurality of control elements. Each piece is analyzed (107, 208, 315) to determine the concentrations of each control element in the piece. The output bins are assigned target concentrations (100, 200, 306) of the control elements that are defined by customer requirements. The method establishes a bin order (110, 210, 310) used during composition checking (112, 212, 316) to place each piece in a selected bin. The selected bin is the highest order bin that can accept a piece while retaining the actual concentration for each control element of the selected bin within the target concentration for each control element of the selected bin. To optimize the value of the input material to be sorted the bin order is established for each piece based on real-time sort parameters that can determine via global optimization of data from similar input material. Global optimization gives best blends of the known unique compositions and weights of the similar input material to maximize the aggregate value of the prescribed output compositions.

Abstract: A portable self-contained data collection system for measuring and collecting vibration data from machines includes an accelerometer which is coupled to the analog input of a data acquisition card. The data acquisition card samples and digitizes the analog signal to produce a time domain digital signal. The data acquisition card output is coupled to a battery-powered portable computer. The battery-powered portable computer includes a database having machine identifications and associated measurement parameters.      The portable computer processes the time domain digital signal according to the measurement parameters associated with a selected machine identification, and produces a frequency domain digital signal by performing a Fast Fourier Transform and other digital signal processing operations. The frequency domain signal is also analyzed in the portable computer to produce predictive maintenance information. A power supply for supplying power to the accelerometer is also included. The accelerometer power supply electrically and mechanically couples the accelerometer to the data acquisition card. It supplies power to the accelerometer when the data acquisition card is activated. The portable self-contained data collection system can be used to measure and collect vibration data from machines and to analyze this data to produce predictive maintenance information.
