Patent CA-2164006-A1 (CA)
Inventor: SAITO NARITOSHI
IPC: H04W72/04
Filed: 1995-04-05
Abstract: In a mobile radio communication system for performing radio communication between a base station and a plurality of mobile stations by a code division multiple access method, a plurality of slots (T1 to T4) for a forward link from a base station (BS) to a mobile station (MS) and a plurality of slots R1 to R4 for a reverse link from the mobile station (MS) to the base station (BS) are set on a first radio frequency f2 in a time-division multiplexing manner.  The slots are set in accordance with the distance between the base station and the mobile station, and the transmission power of the base station in each slot is associated with this distance.  The transmission power is low in the slot associated with a short distance between the base station and the mobile station, and the transmis-sion power is high in the slot associated a long distance between the base station and the mobile station.  The mobile station (MS) detects the received electric field intensity of a pilot/sync signal coming from the base station (BS) with a second radio frequency, and sends the detected information to the base station (BS).  On the basis of the detected value of the received electric field intensity of the mobile station (MS) sent from the mobile station (MS), the base station (BS) determines the distance between the base station and the mobile station, selects the associated pair of slots from among the pairs of slots T1/R1 to T4/R4, thereby allocating the selected slots to this mobile station (MS).

Patent CA-2167237-A1 (CA)
Title: Line smoothing techniques
Inventor: DZIK STEVEN CHARLES
IPC: G06F17/17
Filed: 1996-01-15
Abstract: Improved curve plotting techniques are disclosed for drawing a substantially smooth curve in real time, from a plurality of sampled points, as the points are sampled, on a point-by-point basis. The curve is substantially smooth in that it has a continuously changing slope of G1 continuity, as opposed to a slope which changes in a discontinuous or stepwise manner. The curve plotting is performed by representing the x coordinates of the curve using a parametric equation x = [ax * (t2)] + [bx * t] + [cx], and by representing the y coordinates of the curve using a second parametric equation y = [ay * (t2)] + [by * t] + [cy], wherein ax, ay, bx, by, cx, and cy comprise six unknown quantities, and t is a "dummy" valuable. The derivatives of the parametric equations are employed to calculate and to plot the smooth curve.

Abstract: An iontophoretic drug delivery device (2) including an improved controller (14) is disclosed. More specifically, the controller (14) includes a number of features including recording the number of uses and, after a predetermined number of uses, the controller (14) will no longer operate. Similarly, the controller (14) may include a microprocessor (54) which times a useful life of the controller. Once the timer measures an elapsed period of time, the controller will indicate that it is no longer useable and should be discarded. The microprocessor (54) of the controller (14) may also be used for storage of a unique serial number embedded in the read only memory (45) of the microprocessor (54) for traceability purposes. Additionally, the unique serial number may be used as a security measure to ensure that the correct controller (14) is used with the proper patch (12). The microprocessor of the controller may also be used to record a date, time and/or duration of usage and playback the recorded information to a health-care professional. In addition, the controller (14) and patch (12) include electronics which ensure compatibility of the reusable iontophoretic controller with the specific patch to which it is connected. If the controller (14) determines that the patch (12) is incompatible with the controller, the controller does not apply current to the patch.

Inventor: KOJIMA TOSHIHARU
IPC: H04L27/22
Filed: 1992-12-24
Abstract: Within a differential detection demodulator, a received signal is first quantized by a limiter amplifier and then subjected to frequency conversion by a frequency converter circuit which includes an exclusive OR element, a running average generator consisting of a shift register and an adder, and a comparator.  In response to the output of the frequency converter, a phase comparator outputs a relative phase signal representing the phase shift of the received signal after frequency conversion relative to the phase reference signal.  The phase comparator includes:  an exclusive OR element; an absolute phase shift measurement means consisting of an adder and D flip-flop arrays; and a D flip-flop serving as a phase shift polarity decision means.          Alternatively, the phase detection circuit for generating the relative phase signal may include:  a half-period detection means consisting of a delay element and an exclusive OR element; a phase reference signal generation means consisting of a modulo 2N counter, and a phase shift measurement means consisting of a phase inversion corrector and a D flip-flop array.  The delay element delays the relative phase signal by one symbol period and the subtractor outputs the phase difference signal representing the phase transition over each symbol period of the received signal.  The decision circuit obtains the demodulated data from the phase difference signal.

Title: A method for providing full end to end secure transactional payment services and electronic fund transfer over any unsecured and unreliable network
Inventor: BENZEKRY SAMY
IPC: G07F7/00
Filed: 1997-05-06
Abstract: A method which makes usage of a personal secured device (PSD) comprising a smart token reader coupled to a smart token and a secure transaction server (STS) to provide full end to end transactional security over any network. The Smart Token is inserted inside the PSD. The user then has to enter his own personal activation code key (PACK) to unlock the Smart Token. He then chooses his method of payment, credit or debit. The credit and debit information will have been already loaded into one of the secured memories of the smart token at a secure location for example a bank. Both the identity of the STS and the consumer are legitimized using a bi-directional challenge. The merchant will already have been legitimized by the STS. These steps make sure that the user, holding a legitimate PSD, the merchant and the STS are legitimate.
