Patent HK-1141398-A1 (HK)
Title: Peer-to-peer communication in ad hoc wireless network
Inventor: KUMAR RAVI
IPC: H04W12/06
Filed: 2010-08-16
Abstract: For a peer-to-peer call in an ad hoc wireless network, a wireless device performs discovery of a target wireless device, performs authentication of the target wireless device and generates a session key (e.g., using a pre-shared key or a certificate provisioned on the wireless device), forms an ad hoc wireless network with the target wireless device, and communicates peer-to-peer with the target wireless device via the ad hoc wireless network. The wireless device may perform discovery with a list of identifiers for wireless devices designated to communicate with this wireless device. The wireless device may derive a service set identifier (SSID) used to identify the ad hoc wireless network based on its user-specific identifier (e.g., its phone number) and/or a user-specific identifier for the target wireless device. The wireless device may also performs IP address discovery using the user-specific identifier for the target wireless device.
Patent HK-1143204-A1 (HK)
Title: On-vehicle machine for travel route detection
IPC: G01C/
Filed: 2010-10-15
Abstract: A position estimating section (115) outputs estimation positions (X, Y) for estimating the position where a vehicle is traveling on the basis of the information of a GPS receiver (111), an acceleration sensor (112), a speed sensor (113), and a gyro (114). A correction section (200) position-corrects so as to reduce an error with respect to the latest estimation positions (X, Y) by using the previous estimation positions and the previous map matching positions and outputs the position-corrected correction positions (cX, cY). A map matching section (116) performs a map matching processing to output map matching positions (mX, mY) with reference to road information stored in a storage section (117). Thus, the correction positions (cX, cY) where the position error is reduced are computed, so that the traveling route can be correctly detected.
Patent HK-1150192-A1 (HK)
Title: Relay link harq operation using a smart nack nack harq
Inventor: YU YI
IPC: H04L/
Filed: 2011-04-27
Abstract: A method for preventing a relay node from missing a transmission from an access node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the access node to the relay node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the access node to the relay node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the access node sending the relay node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the relay node receives the grant for the uplink retransmission, the relay node retransmitting the missed data packet.

Patent IT-FI990206-A1 (IT)
Inventor: MARCHI RICCARDO
IPC: D02H3/00
Filed: 1999-10-13
Abstract: Threads are wound onto a warping drum (3) at a constant winding tension by a warp creel (C) and via a deviating roller (1), forming a warp section (M). The increase in the winding diameter is preferably determined based on the ratio of rotations of the deviating roller and the warping drum. The advance of the coning slide is determined or continuously controlled or regulated after the first rotation of the warping drum according to the coning ratio and according to the current measured values of the increase in the winding diameter. The appropriate measured values are registered in a table and stored. As a result, it is possible to work without inputting data relevant to the advance. It is possible to work with or without the equalising roller in order to compensate material-specific properties.

Abstract: Arrangement and method for manoeuvring a floating vessel (1) that is towing a load (10), such as a trawl. The vessel has a block (4, 5) at the aft end, over which at least one tow line (6, 7) extends. The block (4, 5) is moveable transverse to the longitudinal axis of the vessel. The position of the moveable block (4, 5) defines a point of attack for a tension force from the tow line (6, 7). An autopilot (11) is coupled to an actuator (21) moving said block (4, 5) transverse of the longitudinal axis (24) of the vessel (1), in order to change the moment of force of the tension force (W) about a point on the longitudinal axis (24) of the vessel (1). The autopilot (11) is equipped with a calculation unit (12), which detects the tension force (Wl, W2) of the at least one tow line (6, 7) and calculates the moment of force from the tension force (W) on the vessel (1). The autopilot is thus capable of using a change in said moment of force to manoeuvre the vessel (1).
