Patent CA-2250544-A1 (CA)
Title: Vehicle arresting bed systems
Inventor: DIAL CHRISTOPHER T
IPC: B64F1/00
Filed: 1998-02-06
Abstract: Vehicle arresting beds, for installation at the ends of aircarft runways, are effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete (70) having predetermined compressive gradient strength, so that aircraft landing gear is subjected to drag forces effective to slow a variety of types of aircraft, while providing deceleration within a safe range of values. An arresting bed typically includes an entry region (52) of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region (54), which may be tapered into the first region and increase in depth to 30 inches, is formed of blocks having a greater compressive gradient strength.  An aircraft thus experiences increasing drag forces while it travels through the bed, to provide an arresting capability suitable for a variety of aircraft. A protective hardcoat layer (62) of cellular concrete of strength greater than the blocks overlays the blocks to enable service personnel to walk on the bed without damage. Arresting bed systems may be provided in alternative configurations, such as a bed formed of an aggregate including pieces of cellular concrete with or without interspersed pieces of other compressible material and covered by a hardcoat layer.
Patent CA-2251598-A1 (CA)
Title: Droppable battery packs
Inventor: CLARKE JOHN EDWARD
IPC: H04W88/02
Filed: 1998-10-27
Abstract: In a battery pack made up of battery cells encased within a housing made up of a stronger outer housing portion and a weaker inner housing portion, the battery cells are secured to the stronger outer housing portion. Advantageously, the relative motion between the battery cells and the stronger of the housing portions that results when prior art battery packs are dropped, and which causes catastrophic failure of the prior art battery packs, is prevented. The battery cells may be secured to the stronger outer housing portion, for example, by gluing the battery cells to the stronger housing portion, attaching the battery cells to the stronger housing portion by using double-sided sticky tape, molding features into the stronger housing portion that immobilize the battery cells adjacent to the stronger housing portion, or providing screw holes through the stronger housing portion so that screws may engage the battery cell or an appendage thereto.

Inventor: POISSON JACQUES
IPC: A61B17/32
Filed: 1999-02-16
Abstract: Cet extracteur chirurgical est utilisable en laparoscopie. Il inclut un premier tube creux appelé « glissoire » et un second tube creux appelé « poussoir », monté de façon coulissante sur la glissoire. La glissoire a une première extrémité ouverte, une seconde extrémité et une longue ouverture radiale proche de cette seconde extrémité. Un jeu de tiges flexibles appelées « lanières » s'étendent dans le prolongement du poussoir. Ces lanières sont réparties au-dessus de l'ouverture radiale de la glissoire et ont chacune un premier bout fixé de façon rigide au poussoir et un second bout connecté de façon rigide à la glissoire à proximité de la seconde extrémité de celle-ci. Des poignées sont prévues pour appliquer une pression sur le poussoir de façon à déplacer celui-ci depuis une position de repos vers une position d'ouverture plus proche de la seconde extrémité de la glissoire, ceci amenant les lanières à se bomber et s'ouvrir en pétales au-dessus de l'ouverture radiale pour ainsi permettre de saisir dans une direction radiale donnée un organe à extraire du corps d'un patient. Ces mêmes poignées servent aussi à ramener le poussoir de sa position d'ouverture à sa position de repos tout en forçant, si besoin est, sur les lanières pour les débourber et ainsi écraser l'organe saisi par celles-ci en vue de permettre à cet organe de passer dans la glissoire et d'être extrait par la première extrémité ouverte de celle-ci.

Inventor: LANGKJAER CARSTEN
IPC: G01F1/66
Filed: 1999-03-04
Abstract: A method of determining the mass flow rate of a granular material through a channel 1 by means of electromagnetic microwaves where the attenuation and/or the phase-displacement is/are measured by means of a transmitter/receiver equipment 2, 3 at the channel 1. Most of the undesired signals in the measuring equipment are characterised by the phase versus the time varying in both positive and negative direction unlike a phase variation caused by grains in the measuring length, the latter phase variation only involving a phase-displacement in one direction. The undesired signal presents an average phase-displacement of zero and can therefore be deducted in order to obtain an improved measuring accuracy.

Title: System for selecting and accessing portions of an information stream(s) from a television
Inventor: CHEN JEANE
IPC: H04N5/44
Filed: 1999-04-08
Abstract: An improved television is capable of demultiplexing, selecting and distributing information streams of different types of information to the television and to one or more television companion devices (TCDs). The television has a television antenna for receiving a broadcast signal having one or more types of information. Each information type has one or more segments. The television further has a transmitter for transmitting a communication signal to one or more television companion devices. The types of information can include any one or more of the following: a video channel, an audio channel, a data channel, one or more graphical images, and/or one or more animated images. The segments can include any one or more of the following: an audio clip or audio program, a video segment or video program, a still image, animation, graphics, 3D images, and/or a stream of text. The television communicates with the TCDs via a communication link. When the television communicates with the TCDs, it embeds an address into the message which identifies one or more of the TCDs to be the recipient of the message. Information streams and segments which are to be output by the television and/or one or more TCDs are selected by a selector that selects two or more segments from one or more of the types of information where one or more of the segments is displayed, e.g.  on the television, and one or more of the segments are transmitted to one or more television companion devices. In an alternative embodiment, if the automatic selection of information is desired, a Profile Subsystem which contains a profile of profile items in a database of information of interest to the viewer will control selection of one or more of the segments if the segments contain one or more profile items.

Title: Call management apparatus and methods for handling calls during an internet session
Inventor: COBLEY GERRY
IPC: H04M3/428
Filed: 1998-03-11
Abstract: A system and method complete a telephone call connection using an in-progress Internet connection. A user conducting the Internet session is notified of incoming calls, and may make outgoing calls. A voice gateway at the Internet Service Provider (ISP) handles transfer of telephone call information between a public switched telephone system (PSTN) and an ISP-access connection established by the ISP. In this way, voice is transmitted over the relatively real-time connection between the ISP and the user. Calls to the user are first attempted to be routed to the user, but when the user line is found to be busy, the call is forwarded to the voice gateway. The voice gateway receives the forwarded call, and determines whether the line associated with the forwarded call is conducting an Internet session. If such a connection is established, the voice gateway sends a notification over the Internet connection to the user. The user can then decide how to dispose of the call. If the user decides to take the call, voice information continues to be transferred between the user and the person making the call on the PSTN, using the ISP-access connection.
