Patent CA-2269332-A1 (CA)
Inventor: MUSE JAY
IPC: G11B17/04
Filed: 1997-10-30
Abstract: A disk insertion and ejection mechanism for use in a mini disk drive (20) utilizing a disk cartridge having a top shell portion (41) and bottom shell portion (34) with the bottom shell portion being formed from sheet steel. The insertion and ejection mechanism operates by using cooperating cammed surfaces on a mini-cartridge (30) and a movable sled (45) within the mini disk drive.  The cams operate to keep the mini-cartridge raised above the drive spindle (41) during cartridge insertion. When the mini-cartridge is fully inserted into the drive, the cams (58a, b, c, d) in the drive mate with cam openings (58a, b, c, d) on the disk and the cartridge can move down onto the spindle.  Additionally, wedges in the drive (56b) and wedge cut-outs (57b) on the cartridge cooperate to lock a cartridge into the drive during insertion.  During cartridge ejection, the cams within the drive cooperate with the cammed surfaces in the cartridge to raise the cartridge above the spindle whereupon the cartridge is forced from the disk drive. Wings (48) which are coupled to a platform (37) prevent the rotor from decoupling.

Title: Method and apparatus for data communication
Inventor: SYDOR JOHN T
IPC: H04J99/00
Filed: 1999-05-04
Abstract: The Highly Structured Rosette Antenna Array Data Communications System is a high capacity wireless network in which data is communicated from and to remotely located subscribers. The system uses cells that are comprised of a multiplicity of oblong microcells arranged in a circle, giving the cell a rosette-like pattern. like frequency channels are assigned to every N"' microcell, where N is the number of distinctly different frequency channels. The sum of the distinctly different channels is the total bandwidth assigned to the rosette. Typically, if M is equal to the total number of microcells in the rosette, then M/N is equal to the number of like-frequency microcells in the rosette.

Title: Multimedia search and indexing system and method of operation using audio cues with signal thresholds
Inventor: WILLNER BARRY E
IPC: H04H60/31
Filed: 1999-05-12
Abstract: A multimedia search and indexing system automatically selects scenes or events of interest from any media, i.e., video, film, sound for replay, in whole or in part, in other contexts. The entire audio track of a recorded event in video, film, sound, etc., is analyzed to determine audio levels within a set of frequency ranges of interest. Audio clip levels within the selected frequency ranges are chosen as audio cues representative of events of interest in the track.  The selection criteria are applied to the audio track of the recorded event. An Edit Decision List (EDL) is generated from the analysis of the audio track. The list is representative of scenes or sounds of interest as clips for reuse. The clips are reviewed and accepted or rejected for reuse. Once selected, the clips are edited using industry standard audio and video editing techniques.

Patent CA-2274472-A1 (CA)
Title: Authentication between communicating parties in a telecommunications network
Inventor: JUOPPERI JARI
IPC: H04L9/32
Filed: 1997-12-08
Abstract: In known telecommunications systems using multiple access the terminal equipment assumes that the network element is genuine while the network element assumes that the terminal equipment is genuine. This allows false terminal equipment, a false network element or a third party to penetrate the system. The proposed commitment protocol applies bit block commitment known from cryptography and a shared encryption key and the authentication is divided into two parts, whereby one part of it is done by the terminal equipment and the other part is done by the network. The terminal equipment (MS) sends to the network element (BTS) a pseudo identifier (AMSI) which it has formed, whereupon encryption keys (MKEY, BKEY) are exchanged. Only when the network element has revealed its true identity, will the terminal equipment send the required information (IMSI, RND1, RND2) encrypted with a combination of the keys. Finally, the network element authenticates the terminal equipment by using the identity information which it has revealed. Only then can operation commence.

Patent CA-2291557-A1 (CA)
Inventor: WILKINSON DENNIS
IPC: B25H3/06
Filed: 1999-11-26
Abstract: A method for making recessed tray liners for storing objects in a storage container is disclosed. The first step in the method is to size a structural thermoplastic foam liner to fit within a tray. The foam liner is preferably a foamed polyethylene plastic. After the tray is lined with the foam liner, the object or objects to be held in the tray are then heated to a temperature sufficient to soften the thermoplastic foam. The temperature of the heated object is selected to be above the softening temperature of the thermoplastic foam, but below the melting temperature of the foam. After the object or objects have reached the appropriate temperature, the heated object is pressed into the foam lining to form a cavity. The heated foam will flow such that the cavity will conform to the contours of the object being pressed into the foam. After the object is sufficiently pressed into the foam, it is rapidly cooled to a temperature below the softening temperature of the foam. Preferably, the cooling is achieved by quenching the object with a fluid having a temperature lower than the softening temperature of the foam. Water is a suitable cooling fluid.
