  • Patent number: 9179833
    Abstract: Methods for improving gaze tracking are presented. These methods eliminate the need for a separate initial calibration step to determine whether the subject is properly centrally fixated during testing. In one embodiment, whether the subject is centrally fixated is determined by identifying inlier and outlier gaze descriptors; the inliers are assumed to be associated with central fixation. This reduces the total time required for testing. These methods also improve the accuracy of gaze tracking during testing without the need for individual subject calibration. Instead, a database of reference eyes is used. The subject's eye can be compared to the reference eyes, and the mapping function for one or more reference matches can be used to estimate the subject's gaze direction. In another embodiment, previous calibration data from the same subject can be used to determine whether the subject is properly centrally fixated and/or the direction of the subject's gaze.

  • Patent number: 9154283
    Abstract: Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subframe. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.

  • Patent number: 9062495
    Abstract: The present invention relates to a drill comprising a shank adapter (3), a damping piston (5) with a forward end surface (18), a stop end surface (14) for the damping piston (5), a rotation chuck bushing (4) with a forward end surface (16), a stop end surface (17) for the rotation chuck bushing, a impact piston (2) with a brake land (10) with a forward end surface (19), and a brake chamber (8) for braking of the impact speed of the impact piston (2) during idle impacts, which brake chamber (8) has a rear edge (21). According to the invention, the actual idle impact stroke length (L1, L2) of the damping piston is greater than the idle impact braking distance (L3) of the impact piston, where the actual idle impact stroke length (L1, L2) of the damping piston is the shorter of the idle impact stroke length (L1) of the damping piston and the idle impact stroke length (L2) of the rotation chuck bushing.

  • Publication number: 20150163022
    Abstract: It is presented a method of allocating resources of a first uplink subframe being part of a radio frame, each resource being a combination of a frequency range, and a time slot and a code. The method is performed in a network node and comprises: determining a first set of resources allocated for Hybrid Automatic Repeat Request, HARQ, feedback in the first uplink subframe; determining a second set of resources allocated for HARQ feedback in a second uplink subframe being part of the radio frame; identifying free resources in the first uplink subframe by identifying resources of the second set of resources which have no correspondence in the first set of resources; and allocating when a free resource is found, at least part of the free resources to a use other than HARQ feedback. A corresponding network node is also presented.

  • Publication number: 20150049177
    Abstract: Methods and arrangements for detecting osteoarthritis (OA) relate to image processing for enhancing, visualizing and quantifying the fibrillation structure of cartilage using endoscopes. A structure enhancement method comprises obtaining input data, conversion to intensity data, preprocess filtering, intensity fluctuation filtering and contrast enhancement. The degeneration is quantified by a degeneration index (DI) algorithm, applied to the structure enhanced image. Results are then compiled in an output frame presentation.

  • Publication number: 20140376507
    Abstract: The downlink control channels in a control region of each downlink subframe in a telecommunication system are divided into at least one common subset of the downlink control channels and a plurality of group subsets of the downlink control channels, such that the common subset or each common subset will be decoded by every user equipment, and each group subset will be decoded only by a limited group of user equipments. Resource assignment messages for a user equipment can then be transmitted on a downlink control channel of the relevant group subset, to avoid the need for messages to be decoded by a large number of UEs that will not act on them, while broadcast messages can be transmitted on a downlink control channel of the relevant common subset, to avoid the need for messages to be transmitted many times.

  • Patent number: 8897240
    Abstract: Methods for scheduling downlink (DL) data on a downlink subframe from a base station directed to at least one wireless terminal in a wireless network are provided. The methods include selecting a control channel element (CCE) region for a physical downlink control channel (PDCCH) carried in a control region of the downlink subframe; determining whether a DL assignment corresponding to the DL data can be allocated on the selected CCE region based on a load imposed on a corresponding physical resource block (PRB) of a physical uplink control channel (PUCCH) of a future uplink subframe that will carry an ACK/NACK response corresponding to the DL assignment; and allocating the DL assignment on the selected CCE region when it is determined that the DL assignment can be allocated.

  • Publication number: 20140204836
    Abstract: The present disclosure provides coordination of assignments for the physical downlink control channel (PDCCH) in a multi-sector cell based on reuse of CCE resources to user equipment (UE) in different sectors that are well isolated from each other. For non-isolated UEs the CCE resources are either repeated in all sectors for better reception performance, or transmitted in one sector whilst the corresponding CCEs in the other sectors are reserved. In order to achieve coordinated PDCCH assignment there is provided methods for coordinated PDCCH transmission, a system comprising transmission points which are associated with a common physical cell identity and which are controlled by a common network node. There is also provided a corresponding network node and computer readable media comprising computer program code.

  • Patent number: 8709437
    Abstract: The present invention pertains to the identification and initial characterization of CctA, a novel, secreted toxin of Clostridium chauvoei that represents the major cytotoxic activity of C. chauvoei. This toxin confers C. chauvoei its characteristic strong hemolytic activity towards erythrocytes of various species, since anti-CctA antibodies fully neutralize hemolysis by C. chauvoei on standard blood-agar medium or in cell-free supernatants of liquid cultures.

  • Patent number: 8671911
    Abstract: A dual fuel engine operates on a gaseous fuel and a liquid fuel. The engine comprises a supply of gaseous fuel controlled by a first valve, a supply of compression ignitable liquid fuel controlled by a second valve, a control unit for controlling the supply of gaseous fuel and liquid fuel to each combustion chamber in the engine, and at least one knock sensor arranged to detect knock in each combustion chamber and to transmit an output signal proportional to the detected level of knock to the control unit. If knock is detected, the amount of gaseous fuel injected will be reduced while the amount of liquid fuel will be increased. The engine control system will subsequently adapt to the lower grade fuel and perform a calibration to operate as close as possible to the knock limit for the particular fuel.

  • Patent number: 8668338
    Abstract: Systems and methods for providing variable refractive correction in a visual field testing device are presented. One embodiment of the variable refractive correction involves two or more aligned transmissive plates arranged to produce changes in refractive power by translation or rotation of the plates relative to each other. Several alternative designs for providing variable refractive correction are described. The refractive correction can be set manually or automatically based on knowledge of the refractive error of a specific patient and spherical and cylindrical refractive correction are possible. Additional lens systems can be used to extend the range of refractive correction to accommodate a larger patient population.
