Title: Reduction of queuing delays by multiple subgroup assignments
Inventor: SAYEGH SOHEIL
IPC: H04B7/185
Filed: 1997-04-10
Abstract: In a satellite communication system including mobile communication devices, in which each of the mobile communication devices is associated with one of a plurality of subgroups, a method is provided for allocating those devices. According to the method, each of the groups of mobile communication devices is first partitioned into subgroups, each of the subgroups having a queue associated therewith. Subsequently, each of the mobile communication devices is assigned to more than one subgroup having a queue corresponding thereto so as to reduce queuing delays associated with the satellite communication system. In another embodiment, a message to be received by one of the mobile communication devices is transferred to the shorter of the queues corresponding to those subgroups to which the mobile communication device has been assigned.
Patent CA-2252410-A1 (CA)
Title: Secure virtual lans
Inventor: GAGE WILLIAM W A
IPC: H04L12/56
Filed: 1998-11-03
Abstract: The present invention discloses a method for securely adding a new end station to a local area network (LAN) segmented into a number of virtual local area networks (VLANs). The invention is applicable to various types of LANs such as Ethernet and token ring. The LAN comprises an authentication server (AS) which interacts with each new end station before connection to a VLAN is allowed. The method involves the AS administering a test to the new end station, which may involve prompting the new end station for a password or asking it to encrypt a given number using a secret algorithm known only to the new end station and to the AS. The AS examines the results of this test and determines whether the new end station is permitted to join the VLAN. For added security, the new end station can verify authenticity of the AS by administering a test of its own, which may consist of prompting the AS for a password of its own or asking it to encrypt a new number, the new end station subsequently determining whether the AS is indeed genuine before beginning to transmit any further information. In this way, an end station cannot join a VLAN without authentication by the AS and a legitimate end station can verify whether the test it is asked to pass comes from a legitimate source, thereby avoiding network security breaches.

Patent CA-2264136-A1 (CA)
Title: Adjustable static umbrella
Inventor: GLATZ GUSTAV ADOLF
IPC: A45B17/00
Filed: 1997-08-21
Abstract: Disclosed is an adjustable static umbrella with a static mast (2) to which an arm (10) is secured by means of a hinge (12) allowing for the arm to be either adjusted into a use position or collapsed into a rest position and to be tipped about the hinge (12) tilting axle (14) perpendicular to the mast axis. The hinge (12) has a toggle head (80) and a pair of shells (82, 82') symmetrically inverted one to each other, encompassing the toggle head (80) therein and rotatably mounted about the tilting axle (14), while the pair of hinge shells (82, 82') is provided with a length guide perpendicular to the tilting axle (14), in which the arm (10) is inserted. A locking device (90) includes a tilting hinge (92) parallel to the tilting axle (14) and a fastening device (94) allowing for the hinge shells to be pressed one against the other and against the toggle head (80) so that, when said fastening device in the length guide (84) is pulled, the arm cannot be displaced, while the hinge shells (82, 82') encompassing the toggle head cannot be twisted due to pairs of interactive contact surfaces. Releasing the locking device (94) loosens the arm (10) length guide (84), thereby enabling adjustment of the arm, in the area of a tilt angle (.alpha.) limited by two end-stops (116, 116', 118, 120), between a rest position and a use position.

Inventor: CHIN MARTIN
IPC: A61B17/66
Filed: 1997-10-08
Abstract: An apparatus and method for submergible self-retaining distraction osteogenesis are provided. Distraction osteogenesis devices are submerged below a layer of tissue and/or skin layers and are activated based on maximum pressures, rather than constant activation rates. Distraction osteogenesis devices are also self-retaining in that the force in displacing bone segments is transferred substantially through metal plates, rather than screws or fixation points. In particular, zygomatic (10), alveolar (69), and mandibular (93) distraction osteogenesis devices are provided. The zygomatic and alveolar distraction osteogenesis devices include a submergible first and second metal plate (15, 16, 63, 64) along with a threaded rod (11, 60). The zygomatic and alveolar distraction osteogenesis devices are activated using a cannula (31, 72), torque wrench adapter (32, 73), and torque wrench (30). The mandibular distraction osteogenesis device (93) includes a palate expander (90) having a plurality of rods (94, 95) used in coupling first and second self-retaining Ushaped plates (91, 92). The mandibular distraction osteogenesis device is activated using an allen wrench (102). In order to allow for maximum bone growth and/or distraction, a maximum pressure between bone segments is applied by a torque or allen wrench.
