Patent CA-2224009-A1 (CA)
Title: Monostable active latch for a disk drive actuator
Inventor: HARWOOD GORDON A
IPC: G11B21/22
Filed: 1996-06-07
Abstract: A mono stable active latch apparatus is disclosed for use in a hard disk drive (10) which has a housing (18), a rotating data storage disk and an actuator mounted in the housing. The actuator (12) controllably positions a read/write head over a predetermined portion of the disk and includes a voice coil motor coil (16) carried by a yoke portion of the actuator. The active latch uses a permanent magnet to bias an elongated rotatable latch arm (32) into engagement with the actuator when the actuator is positioned in the landing zone. An electromagnet coil, positioned between the magnet and the magnetic return plates, when energized, counters this bias, permitting the latch arm to rotate, counterclockwise, out of engagement with the actuator. When the coil is deenergized, the permanent magnet provides a clockwise torque on the arm, raising the latch end of the latch arm to a first position out of the path of the actuator. When the coil is energized, the latch end of the latch arm is driven to a second position beneath the rear end of the actuator. If the coil is deenergized while the actuator is positioned in the landing zone of the disk, the latch end of the latch arm catches and latches the actuator, preventing further rotation of the actuator until the coil is again energized and the actuator moved away from the landing zone.

Patent CA-2225430-A1 (CA)
Inventor: SANSONE RONALD P
IPC: G06Q10/04
Filed: 1997-12-22
Abstract: The invention is a method for channeling message traffic along an optimal path to its intended destination. The method is accomplished by drafting a message and a corresponding destination address together in electronic form. The message and address are coupled with a set of parameters which define a method of conversion of the electronic form of the message and address to a tangible form. The message and address are transmitted together with the conversion parameters, as a packet, to a routing facility via a digital carrier. The routing facility will select an optimal transmission path whereby the packet will be transmitted to the terminal node for conversion and printing. The selection of an optimal path is made by analyzing a set of weighted factors pertaining to a set of possible pathways. The combination of weighted scores will be used to determine which path has the highest weighted score. The path with the highest weighted score will be selected, and the transmission will be initiated by the routing facility along that path. The terminal node comprises receiving means for receiving the packet and printing means for converting the electronic message and address to human readable form by printing the message on a medium and printing the destination address on an envelope, from these a finished mail piece is formed and placed into a local mail stream for delivery to the destination address.

Title: Finger assignment system for a multiple finger receiver and method thereof
Inventor: BASSO JAMES
IPC: H04B1/10
Filed: 1998-06-25
Abstract: A finger assignment system prevents the assignment of receiver fingers to the same multipath component and to avoid the inefficiencies associated with current schemes. The finger assignment system accomplishes this by setting an offset or delay difference between the offsets or delays assigned to any two fingers, and if the offset or delay difference is violated, adjusting the offset(s) or delay(s) of one or both of the fingers to differ from each other by at least the offset difference. In certain embodiments, the receiver establishes an offset or delay difference between the offsets or delays assigned to any two fingers which are receiving signals from the same antenna. If the offset difference is violated, the finger assignment system adjusts the assigned offset or delay of the weaker finger to differ from the assigned offset of the stronger finger by at least the offset difference. Thus, the receiver scheme according to the principles of the present invention tends to have more receiver fingers tracking more multipath components a higher percentage of the time. The more effective use of the receiver fingers according to the principles of the present invention tends to increase the multipath diversity of the receiver and to improve the average SNR of the receiver.

Patent CA-2248408-A1 (CA)
Inventor: VERMEER FULPS VINCENTINUS
IPC: H04W52/02
Filed: 1998-09-24
Abstract: A time-division radio is disclosed that can use a lower-power energy source than radios in the prior art. An illustrative embodiment of the present invention comprises a time-division transmitter that has a transmit mode and an idle mode, a primary energy storage device and a secondary energy storage device. The radio uses the secondary energy storage device as a kind of "power cache" in which to store power when it is in abundance and from which to draw power when it is scarce. When the transmitter is in idle mode, the primary energy storage device charges the secondary energy storage device and powers the transmitter. But when the transmitter is briefly in transmit mode, and, therefore, requires more power than the primary energy storage device alone can supply, the secondary energy storage device discharges to supplement the power from the primary energy storage device and satisfy the transmitter's power requirements.

Title: Controlling operating states of a mobile station in a packet radio system
Inventor: KARI HANNU H
IPC: H04W76/04
Filed: 1997-03-27
Abstract: The invention relates to packet radio networks and particularly to controlling operating states of a mobile station in a packet radio network. A mobile station (MS) has an active state and a standby state. In the active state, the mobile station performs data transmission and updates its location more often than in the standby state. The mobile station changes from the active state to the standby state if there is no data transmission during a predetermined period. The packet radio network (SGSN) may also direct, if required, the mobile station (MS) from the active state to the standby state. According to the invention, the mobile station (MS) transmits to the packet radio network a short pseudo data packet either before the timer expires or in response to a command transmitted by the packet network to change the state (GO STANDBY) when the mobile station wants to stay in the active state.
