Title: Concurrent hardware-software co-simulation
Inventor: TZORI YIFTACH
IPC: G06F17/50
Filed: 1998-06-12
Abstract: A digital logic simulation/emulation system (20) operates in an engaged operating mode in which a digital-logic simulation process (22) transmits stimulation-control data to a hardware pod (32) for controlling stimulation of a digital logic circuit. In response to the stimulation-control data, the hardware pod (32) performs a stimulation-response cycle, and then sends response data from the digital logic circuit to the simulation process (22).  The simulation process (22) and the hardware pod (32) may also operate in a disengaged operating mode in which each operates independently of the other without exchanging stimulation-control data or response data. Operation of the system (20) in the disengaged mode commences if a disengagement event occurs in the hardware pod (32). Operation of the system (20) in the disengaged mode terminates if the simulation process (22) sends stimulation-control data to the hardware pod (32), or if the hardware pod (32) sends response data to the simulation process (22).

Title: Method and apparatus for capacity driven intra-cell handover in a cellular telephone network
Inventor: OESTRUP PETER
IPC: H04W12/10
Filed: 1998-08-18
Abstract: Existing communication connections in a cellular telephone base station can become allocated to communication equipment in a less than optimal fashion. To address this problem a detector (200) identifies (300) when an existing communication connection routed through the base station is terminated. The detector informs a processor (210) which calculates a channel allocation for the remaining communication connections currently routed through the base station which optimizes channel utilization. The optimal channel allocation is then implemented through intracell handovers (330, 350 and 370). The optimal channel allocation is based on assigning an existing communication connection having a lower channel rate (340 and 360) requirement than is available on the communication channel currently carrying the existing communication connection to a communication channel having a lower channel rate capacity or assigning an existing communication connection from a less restrictive communication channel to a more restrictive communication channel (320) having the same or lower channel rate capacity as the current communication channel.

Title: Materiaux en feuille, absorbants, protecteurs et a usage multiple
Inventor: HAMILTON PETER WORTHINGTON
IPC: B65D81/26
Filed: 1998-08-10
Abstract: La présente invention concerne un matériau en feuille (10), à usage multiple, comprenant une couche absorbante (20) présentant des première et seconde surfaces opposées, un système surélevé (40) sensiblement non absorbant et sensiblement imperméable aux fluides, associé à la première surface et s'étendant transversalement sur celle-ci, ainsi qu'une couche barrière (30) imperméable aux fluides, couvrant de manière sensiblement continue la seconde surface. Le système surélevé peut comprendre plusieurs éléments surélevés ou un réseau continu de tels éléments, et il peut être agencé de la manière voulue. Des couches adhésives optionnelles (35) ou des éléments disposés sur la surface de la couche barrière faisant face à une surface de support peuvent apporter une stabilité accrue lors de l'utilisation de l'invention. Le système surélevé peut être formé monobloc avec la couche barrière, ou il peut être formé par mise en contact direct avec celle-ci, de façon que les forces appliquées sur le système surélevé soient transmises à la couche barrière, évitant ainsi la couche absorbante.

Patent CA-2302922-A1 (CA)
Title: Dual coil coin identifier
Inventor: KISS BILL
IPC: G07D5/08
Filed: 2000-03-29
Abstract: The coin identification device comprises a gravity fed chute structure having an opening for receiving a coin to be identified, walls to guide the coin as it moves through the chute and an opening for the coin to exit. A wake-up circuit with sensing coils mounted near the chute opening provides an output signal when the presence of a coin is detected. Two coin sensing circuits, each having an oscillator with a particular coil arrangement are used to sense the characteristics of the coin passing through them. The first coin sensing circuit includes a coil arrangement having a coil mounted on the chute with its axis in the direction of the coin path such that the coin will pass through it and forming part of a first oscillator to create lines of flux parallel to the coin path. The second coin sensing circuit includes a coil arrangement having a coil mounted on a U-shaped core with two substantially parallel legs connected at one end by an arm that is mounted about the chute to have the coin pass in the gap between the core legs. The second coil arrangement forms part of a second oscillator to create lines of flux perpendicular to the plane of the coin passing through the chute. The first and second oscillators are adapted to oscillate at one or more base frequencies. The frequency shift of the first oscillator is measured as the coin passes through the first magnetic field and the frequency shift of the second oscillator is measured as the coin passes through the second magnetic field to generate signatures of the coin characteristics. A microprocessor compares the generated signatures to known coin signatures to identity of the coin.

Patent CA-2308276-A1 (CA)
Inventor: PAIAM REZA
IPC: G02B6/28
Filed: 2000-05-10
Abstract: A wavelength demultiplexer having a substantially flat output response within its passband is disclosed. The demultiplexer comprises a first wavelength demultiplexer optically coupled to a second wavelength demultiplexer. The first wavelength demultiplexer has a free spectral range approximately equal to channel spacing of the second wavelength demultiplexer thereby providing the substantially flat output response within the passband. The first wavelength demultiplexer is a resonant optical cavity, absent distinct output ports, and light propagating between the first wavelength demultiplexer and the second wavelength demultiplexer is unguided.  The absence of distinct output ports in the first wavelength demultiplexer reduces ripples in the substantially flat output response within the passband. Alternatively, the first wavelength demultiplexer is replaced by an MMI-phasar.
