Patent CA-2257203-A1 (CA)
Title: Medium access control scheme for data transmission on code division multiple access (cdma) wireless systems
Inventor: MERMELSTEIN PAUL
IPC: H04B7/26
Filed: 1996-11-19
Abstract: A synchronous discontinuous transmission medium access control (SDTX-MAC) method and apparatus for more efficiently using existing uplink channels by sharing these uplink channels between multiple terminals engaged in bursty data transmission. This is accomplished by assigning each mobile terminal an individual time slot and by not requiring each mobile terminal to broadcast its identity. This results in a reduction in the number of receivers on each base station and a reduction in the length of the synchronization message.

Title: Stationarily-mounted seating structure having electrical and data outlets
Inventor: GEVAERT STEVEN C
IPC: A47C7/62
Filed: 1999-01-14
Abstract: A seating structure including a series of seat assemblies each consisting of a pair of spaced side supports, a seat pivotably mounted between the side supports, a back fixed to the side supports, an electrical outlet positioned on one of the side supports, and at least one data outlet positioned on one of the side supports.  Each of the side supports includes an outlet housing affixed to the lower surface of an arm rest contained on the side support. The outlet housing extends inwardly toward the seat surface and provides the seat occupant with an electrical outlet and at least one data outlet. The electrical wiring and data line for each seat assembly pass through a wireway contained in the seat back. A branch electrical power conduit passes through the side support and into the seat back where is it connected to the supply of electrical power. Likewise, a data line extends from the wireway contained in the seat back into the side support where it is connected to the data outlet. The wireway is used to supply power to each of the seat assemblies positioned in the continuous row of seating. In this manner, a single power connection through one of the side supports allows power to be supplied to a continuous row of seats.

In this way, the mixing chamber is operated independently of the delivery chamber for preparing the bone cement and, once prepared, easily transferred from the mixing chamber through the delivery chamber for immediate use.
Patent CA-2270387-A1 (CA)
Inventor: SUTTER HERBERT P
IPC: G06F17/30
Filed: 1997-10-29
Abstract: An independent distributed database system comprising a plurality of sites wherein all users at all sites work off-line with local data. All application transactions are against the local database only, and every site stores "all and only" the data it needs. On-line transactions occur only in the background, including a periodical "synch" between sites that transmits any changes to data of interest to that site. If the background operations are interrupted or the network is temporarily unavailable, the user does not see new changes made at other sites until the data link is available again, but is otherwise unaffected. It is a feature that no site acts as a "server" for any other site. Some sites may store more data or have more users than others, but all sites are logically peers.

Patent CA-2277631-A1 (CA)
Title: Transmission channel for the electrically isolated transmission of digital signals
Inventor: KONRAD STEPHAN
IPC: H04L5/16
Filed: 1999-07-16
Abstract: For the electrically isolated transmission of digital signals, an isolating path (IP) of the channel formed by means of a transformer is used. The channel further comprises a conversion stage (SC1) for converting the digital signal (txd1) to a transmissible coupling signal (txt1) and a conversion stage (SC2) for converting a coupling signal (rxt2) to the digital signal (rxd2). This conversion is accomplished by means of a monostable multivibrator. The coupling signal (txt1) is a square-wave voltage (AU2) which is generated by means of a delay circuit (4) in the conversion stage (SC1) and is converted on the isolating path (IP) to a square-wave voltage (AU3) serving as the coupling signal (rxt2). Furthermore, the direction of transmission is switchable in operation by means of activatable digital-signal ports (TXD1', RXD2', TXD2', RXD1') of the channel. The activation is effected by means of selection signals (rxa1', rxa2'). When no signal is being transmitted, the channel is in a defined initial state. The channel has low power consumption and the transmitted signal is highly immune to electromagnetic interference.

Filed: 1999-07-16
Abstract: A pin retainer is provided which, according to one embodiment, includes a spring positioner for engaging a spring so as to retain the spring in position laterally relative to the pin retainer.      Typically, the spring positioner is a recessed pocket defined by the rear end of the retainer body for receiving one end of the spring. The pin retainer of another embodiment includes a ferrule coupling portion for engaging the ferrule in a manner that is independent of guide pins so as to retain the pin retainer in position rotationally relative to the ferrule without requiring guide pins to extend through the ferrule for engagement by the pin retainer.      Typically, the ferrule coupling portion is a projection extending outwardly from the forward end of the retainer body for engaging a corresponding recess defined by the ferrule. As a result of the pin retainer, a corresponding method for mounting a fiber optic connector upon the end portion of an optical fiber is also provided which permits the connector to be assembled within a jig prior to mounting the connector upon the optical fiber and prior to inserting guide pins through the ferrule for engagement by the pin retainer.

IPC: B60D1/62
Filed: 1999-10-14
Abstract: The invention provides for the management and protection of excess lengths of utility cables in extendable semi-trailers. Utility cables are affixed to the front and rear sections of an extendable semi-trailer and are threaded through a protective carrier that can bend in only one direction. This directionally restrained carrier rests within a channel that shields the carrier and the cables from wear and tear and which constrains the bending of the carrier to one trans-channel turn. As the trailer is extended, the front and rear sections of the trailer and therefore the ends of the cables and carrier will move relative to one another. The cables and carrier move within the channel from a generally "U"-shaped pattern to a generally "J"-shaped pattern as the trailer moves from the retracted to the extended position.
