Abstract: Known sequences are detected and identified in a fast fading environment using a segmented correlator and FHT (Fast Hadamard Transform) architecture. The incoming sequence of samples or data is segmented into blocks. Each block is individually detected using a correlator/FHT segment. Each sequence identifying output of each correlator/FHT segment is summed with the corresponding output of other correlator/FHT segments. Each sum is compared with a threshold to determine whether a particular sequence has been detected and identified.

Abstract: A printer on a network is selected to receive a file to be printed on the instigation of a mobile device. At least one user preference is wirelessly sent from the mobile device to a networked print controller. The print controller has access to the predetermined properties of a plurality of networked printers. At least one of the predetermined properties of the printers are then matched with the at least one user preference, which results in the selection of one or more printers which are suitable for printing the file. The predetermined properties of the networked printers can include the strength of signals between a wireless communications point on the network and the printers to identify the closest set of printers, and/or the size of paper the printer holds, the number of print jobs in the print queues, etc.

Abstract: A time division multiple access communication system is disclosed, in which down link data are transmitted over a data channel in repeated time frames each containing a plurality of time slots. Down link set up information is transmitted over a control channel to indicate from which time slot a user terminal should extract data. Each frame on the data channel includes a user packet flag to indicate whether or not each time slot in the frame contains data. Each user terminal is responsive to the set up information and to the user packet flags to extract data from its assigned time slot in those frames which the slot is indicated to contain data.

Abstract: A printhead gap adjustment mechanism for use in an imaging apparatus includes a worm gear coupled to a carrier shaft to transmit a rotational motion to the carrier shaft. A worm screw is positioned in rotational cooperation with the worm gear, the worm screw having an axis of rotation. A first cam is coupled to the carrier shaft. A first cam follower surface is disposed in proximity to the first cam. A guide device guides the carrier shaft in a translational direction substantially parallel to the axis of rotation of the worm screw. A rotation of the worm screw transmits rotational motion to drive the first cam via the worm gear and the carrier shaft, the first cam engaging the first cam follower surface to effect a translational motion of the worm gear in the translational direction, thereby effecting a movement of the printhead in the translational direction.

Abstract: A carrier assembly includes a carrier housing defined in part by a wall having an interior surface, an exterior surface and a distal end. A slot extends between the interior surface of the wall and the exterior surface of the wall, the slot being spaced apart from the distal end. At least one first projecting member is positioned adjacent the slot. A circuit card is mounted to the exterior surface of the wall. A printhead cable in the form of a flexible printed circuit is provided having a first end portion and a second end portion. The first end portion is secured to the circuit card. The flexible printed circuit is laced through the slot, the flexible printed circuit including at least one hole to correspondingly receive the at least one first projecting member. The second end portion passes over a portion of the interior surface and around the distal end of the wall. An attachment mechanism secures the second end portion to the exterior surface of the wall.

Abstract: Method for controlling the level of tractive efforts in a train having a first locomotive at a head end of the train, constituting a lead locomotive, and a second locomotive positioned in the train behind the lead locomotive, constituting a remote locomotive, with the remote locomotive being configured to selectively operate in either of two modes of operation, such as a first mode in which the locomotive operates at a full tractive effort level of operation and a second mode in which the locomotive operates in a partial tractive effort level of operation producing a tractive effort which is less than the full tractive effort of the locomotive. The method allows selecting (e.g., at the lead locomotive) one of the two modes of operation for producing a level of tractive effort appropriate for conditions as the train moves along a length of track. The method further allows transmitting a signal indicative of the selected mode of operation from the lead locomotive to the remote locomotive.
