Title: Mobile station user group operation
Inventor: DIACHINA JOHN
IPC: H04B7/26
Filed: 1996-03-15
Abstract: A method for completing a call in a cellular communication system to a mobile station which is part of a user group is disclosed. First, a user group identification code is assigned to a first plurality of mobile stations, wherein said first plurality is less than the total number of mobile stations in the system. A page message from the cellular system to the user group is transmitted using the user group identification code when a terminating call has been requested to the user group. A user group specific page indication is then generated at the first plurality of mobile stations in response to receiving the page message. A page response message is then transmitted to the cellular system from mobile stations whose users acknowledge the page indication. Finally, a channel assignment for the call is granted to the mobile station which sends the first received page message received at the cellular system.

Patent CA-2228920-A1 (CA)
Title: Twisting-cylinder display
Inventor: CROWLEY JOSEPH M
IPC: G09F9/37
Filed: 1998-02-05
Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays. The substrate containing the cylinders can be fabricated with the swelled-elastomer techniques known from spherical-particle gyricon displays, with a simple agitation process step being used to align the cylinders within the sheeting material. Techniques for fabricating the cylinders are also disclosed.

Title: Bolt-on cutting apparatus
Inventor: CHAPPELL CHARLES J
IPC: B60S1/68
Filed: 1998-03-16
Abstract: In the operation of machines such as landfill compactor, it is common to provide a shear assembly that is mounted between the axle assembly and a wheel that is rotatably mounted thereon to sever material that would otherwise become entrained about the axle assembly.  Material of relatively large gauge may become lodged within the shear assembly and create large loading forces between the wheel and the axle components that have been known to damage various drive train components.  The present invention provides a cutting apparatus that has a first and second shear blade mounted to the axle assembly and wheel respectively.  The second shear blade is bolted to the wheel in a manner wherein selected ones of the mounting bolts are sized in a manner in which forces of a preselected magnitude will shear the bolts thus limiting the amount of force transmitted to the drive train components.

Filed: 1998-05-19
Abstract: Une version de la présente invention consiste en une méthode de commande de téléphones mobiles transmettant des accusés de réception de BSM (messages courts diffusés) simultanément sur le même ensemble de canaux d'accès aléatoire. Dans cette version, le système de communication sans fil commande les transmissions d'accusés de réception des BSM en utilisant des restrictions de canal d'accès aléatoire et des techniques d'accès aléatoire. En particulier, les restrictions de canal d'accès aléatoire réduisent les collisions entre les  téléphones mobiles qui accusent réception des BSM et les téléphones mobiles utilisés pour des appels, grâce à l'affectation d'un ou de plusieurs canaux d'accès aléatoire particuliers pour la transmission des accusés de réception de BSM, et les techniques d'accès aléatoire réduisent les collisions entre les téléphones mobiles qui accusent réception des BSM en répartissant les transmissions des accusés de réception de BSM sur une certaine période.
Patent CA-2238702-A1 (CA)
Title: Motor mount
Inventor: ZELINSKI ELGIN
IPC: F16H7/14
Filed: 1998-05-27
Abstract: An apparatus for use with motor-driven assemblies is described.  The motor-driven assembly comprises a motor, a pulley driven by the motor, a driven element and a belt drive connecting the pulley and the driven element.   The apparatus comprises a motor base and a pivot base. The motor is arranged on the motor base such that, due to the positioning of its mass, the motor will pivot away from the drive element. However, pivoting in this direction is opposed by the belt drive. Thus, as the belt drive tension reduces, the motor will pivot away from the drive element, thereby tightening the belt. A one-way restraining means connecting the pivot base and the motor base prevents the motor from pivoting back toward the drive element, thereby keeping the belt drive taut and retaining drive design expectations.

Title: Method and apparatus for determining an identifying bit sequence in a radio frequency waveform
Inventor: SUOMINEN EDWIN A
IPC: H04L7/04
Filed: 1998-08-05
Abstract: The characterization and detection of an identifying bit sequence is performed without digital demodulation or bit synchronization. A waveform containing a digital bit sequence is cross-correlated with waveforms corresponding to a set of known bit sequences. For each bit sequence, one of the inputs to a correlator is shifted through all possible values of correlation lag while the correlation match for each lag value is compared to the others so that a peak correlation between the two waveforms is determined. The peak correlation values for each of the known bit sequences are then compared to characterize how closely the received radio frequency signal corresponds to each of the known bit sequences. The bit sequence that most closely corresponds to the waveform of the received signal may then be identified. Applications include the identification of the N-AMPS DSAT and the GSM training sequence an a cellular radio scanning receiver.
