Patent GB-2378860-A (GB)
Title: Time slot allocation within a frame of a multicarrier TDMA system
Inventor: RAYNE MARK WENTWORTH
IPC: H04J4/00
Filed: 2002-06-28
Abstract: A TDMA system with plural carrier frequencies divided into regularly repeating frames allocates for use as a communications channel, a pattern of timeslots on more than one carrier frequency in a single transmission frame. Communication stations can transmit and receive more than one carrier frequency simultaneously. Communication channels consisting of simultaneous timeslots on different carrier frequencies are assigned to parties requesting a call depending on the particular data rate requested for the call. The system determines how many timeslots per frame the requested data rate responds to and then allocates the appropriate number of timeslots to the channel. Although an integer number of timeslots per frame must be allocated to the channel, the slots may otherwise be allocated in any way desired. Thus, for example, a data rate corresponding to six timeslots per frame could be provided by a channel (channel a) which consists of slot 1 on each of the six different carriers 1-6 or by a more dispersed allocation of slot 3 on carriers 1 to 4 and slot 4 on carriers 3 and 4 (channel c). A rate of three slots per frame could be provided by a channel b on carriers 1- 3. These slot patterns repeat for selected successive frames. Other aspects include allocating timeslots/frequencies based on particular signal strength indications, allocating data to timeslots according to predetermined ordering schemes to minimise retransmission request delays, using different timeslot patterns on uplink and downlink channels, interleaving data on each carrier frequency of a multicarrier separately from the other carriers to allow for frequency changes (c.33,56) and using contiguous blocks of adjacent carrier frequencies.

Title: Adjusting eccentric weight vibrator
Inventor: POTTS DEAN R
IPC: B06B1/16
Filed: 2002-08-05
Abstract: A vibratory mechanism 26 for a compactor (Fig 1) with a vibrating drum 14,16 comprises a first eccentric weight 50, a second coaxially rotatable eccentric weight 52 and a clutch 60 between them, the clutch allowing relative rotation of the weights to vary the vibration amplitude of the mechanism. The outer weight 52 is directly driven from motor 28 via shaft 58 and stub shafts 56. The inner weight 50 is supported on an inner shaft 54 and driven along with the outer weight via a clutch 60 disposed between the shafts 54 and 56. The clutch 60 is a torque limiting slip clutch of the ball ramp type as shown, or jaw type with spring tension or friction disc type. With the vibratory mechanism at rest, the weights are positioned 180 deg out of phase so the amplitude is zero. The motor accelerates the weights up to speed slowly so that the slip clutch does not activate and the amplitude does not change. At a certain speed, the motor 28 abruptly changes speed, the clutch 60 slips, and the weights move towards each other to increase the vibration amplitude. The power applied to the motor 28 is automatically controlled (controller 80, Fig 4).

Title: A method and apparatus for the optimal predistortion of an electromagnetic signal in a downhole communication system
Inventor: HAASE MARK CHRISTOPHER
IPC: E21B47/12
Filed: 2001-02-09
Abstract: A method and apparatus for communicating a desired target signal along a piping structure is provided. Because of the lossy communication path presented by the piping structure, an input signal, which is transmined from a first location on the piping structure, is consciously predistorted prior to transmission. The amount and nature of the predistortion applied to the input signal is determined by mathematically modeling the communication path between the first location and a second location. Predistortion of the input signal results in reception of an output signal at the second location that closely approximates the desired target signal. Application of this predistortion method of communicating is described in the context of communicating in the borehole of a petroleum well.

Title: System and method of managing supplementary features in the presence of a proxy switch in a mobile communications network
Inventor: NAQVI SHAMIM A
IPC: H04W92/12
Filed: 2001-11-21
Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload mobile traffic it provides a platform for new communication services. The proxy switch includes signaling message handling logic that receives signaling messages from the MSC and BS in accordance with a mobile signaling protocol. State logic maintains state information of call sessions and mobile stations (MSs) used within the mobile communications network. Message interception logic detects whether a signaling message from an MSC is a new call originating message and if an MS addressed in such a new call originating message is involved in a call. The message interception logic also prevents the new call originating message from being forwarded to the BS servicing the addressed MS. Message conversion logic converts the new call originating message to a feature notification message, and message transmission logic issues the feature notification message to the BS servicing the addressed MS.

Title: Performing diagnostic operations upon a data processing apparatus with power-down support.
Inventor: BLASCO ALLUE CONRADO
IPC: G06F1/32
Filed: 2004-06-22
Abstract: A system-on-chip integrated circuit 2 is provided with multiple data processing circuits 4, 6, 8 each with an associated diagnostic interface circuit 16, 18, 20 connected via a diagnostic transaction bus 14 to a diagnostic transaction master circuit 12. The diagnostic master transaction circuit 12 issues diagnostic transaction requests to the diagnostic interface circuits 16, 18, 20. If the associated data processing circuits 4, 6, 8 are powered-down, or otherwise non responsive, then the diagnostic interface circuit 16, 18, 20 returns a diagnostic bus transaction error signal to the diagnostic transaction master circuit 12. A sticky-bit latch (30) within each diagnostic interface circuit 16, 18, 20 serves to record a power-down event and force generation of the diagnostic bus transaction error signal until that sticky bit is cleared by the diagnostic mechanisms . This ensures the diagnostic mechanisms are made aware of the power-down event so they may take any appropriate remedial action that might be necessary as a result of that power-down event.
