Acquisition method and device for seismic exploration of a geologic formation by permanent receivers set on the sea bottom

InactiveUS6932185B2Good flexibilityFine divisionSeismic energy generationSeismic signal receiversGeophoneHydrophone

A method and device for seismic exploration of a subsea geologic formation by pickups set on the sea bottom and intermittently connectable to active data acquisition stations (11) brought nearby. Permanent passive reception stations (1) comprising a heavy pedestal provided with housings for seismic pickups (geophones (6), hydrophone (7) which receive acoustic or seismic signals from the underlying formation are arranged at the bottom of the water body. When collection sessions for the signals received by the pickups are scheduled, mobile active acquisition stations (11) connected to permanent passive reception stations (1) are positioned at the bottom of the water body. The signals picked up are then recorded, for the time required to carry out at least one session of acquisition and recording of the acoustic or seismic signals received by the passive stations in response to the emission of seismic waves by one or more seismic sources. The mobile active acquisition stations (11) are thereafter recovered at the surface and the records acquired by each one are transferred to a central collection laboratory.

Bluetooth sniff mode power saving

ActiveUS20050169201A1Save powerConvenient and accuratePower managementSynchronisation arrangementPrimary stationBluetooth

A Bluetooth master radio frequency unit addresses a slave radio frequency unit, to enable the slave to synchronize to the master, by sending poll packets and optionally null packets over an active link, the master being arranged so that receipt of a response from the slave unit to a poll packet is sufficient to maintain the active link. The slave unit does not have to respond to all of the poll packets. This approach can allow the slave to preserve more (transmit) power by going into a deep sleep mode in which a low power oscillator may be used while still allowing the master unit to detect whether the slave has resynchronized or not (and thus to update a Link Supervision Timer, for example).

Joint search method for UAV multiobjective path planning in urban low altitude environment

ActiveUS20180308371A1Lower requirementReduce computational complexityRemote controlled aircraftTarget-seeking controlSafety indexPath plan

A joint search method for UAV multiobjective path planning in an urban low altitude environment first constructs a static safety index map based on static known obstacles. Meanwhile, based on proactively detected obstacles that are not marked on a geographic map by a UAV, the method constructs online a dynamic safety index map. Second, a multiobjective path planning problem is solved using a joint offline and online search method. Moreover, this method first plans offline the least cost path from a starting point to an end point and then invokes the online search scheme to replan online a changed path when the UAV detects unknown obstacles. Thus, the UAV can avoid dynamic obstacles effectively. The online search scheme has a small search space and can quickly replan a safe path for the UAV, thus satisfying the requirement of UAV on the real-time path planning.

The first yaw angle return control is started at a first start time when the first interruption condition is established. The actuator is controlled under the first yaw angle return control so that yaw angle at a first finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the first start time. The first finish time comes when a first control execution time passes from the first start time. The actuator is controlled under the second yaw angle return control so that yaw angle at a second finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the second start time. The second finish time comes when a second control execution time longer than the first control execution time passes from the second start time.

Phase change material (7;7a,7b) having a phase change temperature within a preferred operating temperature range is employed in order to maintain the battery temperature within the preferred operating temperature range during extreme ambient temperature conditions. When the temperature of an ambient medium (21) so allows, a transfer of heat between the phase change material (7;7a,7b) and ambient medium (21) is effected for quickly restoring the capability of the phase change material (7;7a,7b) to maintain the battery temperature at the phase change temperature. Otherwise, thermal insulation between the phase change material (7;7a,7b) and the ambient medium (21) is provided.

The rotation stand is rotatably attached to the base through the axis aperture. The adjusting mechanism has a connection end and an adjusting end. The connection end is coupled with the rotation stand and is movable together with the upper stand to generate displacement relative to the base. The positioning device is coupled with the adjusting end and passes through the first slot. When the upper stand rotates relatively to the base, the adjusting mechanism drives the positioning device to move along the first slot. The first slot limits the angular rotation of the rotation stand and the positioning device and selectively constrains the relative displacement between the connecting unit and the base.
