摘要： A method for detecting communication failures on a network comprising a server computer connected to multiple client computers, said server and client computers communicating through the transmission of data packets via the network. The method includes the step of periodically sending an echo request message from the server computer to the client computers. Each client computer, following receipt of the echo request message, sends an echo reply message back to the server computer. The method further includes the steps of monitoring the rate at which data packets are received by the server computer; and reducing the frequency at which echo request messages are sent from the server computer to the client computers during periods when the rate at which data packets are received by the server computer exceeds a re-configurable rate value. The frequency at which the echo request messages are sent is dependent upon the rate at which data packets are received by said server computer.

摘要： A receiver architecture is described for phase noise compensation in the presence of inter-channel interference (ICI) and inter-symbol interference (ISI), particularly for time-frequency packing (TFP) transmissions. The receiver includes a coarse phase noise (PN) estimator, a PN compensation module, an ICI cancellation module, an ISI compensation module, a FEC decoder, and an iterative PN estimator. The iterative PN estimator receives log likelihood ratio (LLR) information from the decoder and provides an iterative PN estimation to the PN compensation module. The decoder also provides LLR to the ISI compensation module, and to at least one other receiver for another subchannel that is immediately adjacent in frequency. The ICI cancellation module receives decoder output from at least one adjacent subchannel, which the ICI cancellation module uses to provide a ICI-cancelled signal.

摘要： The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

摘要： Now in this busy world, users heavily rely on the internet to browse over the internet map such as Google map, Mapquest map, Baidu map, QQmap, Gaode map, Soho map etc to find and identify the targets users interested through different markers, the Markers on internet maps are first windows or first doors to enter into internet world to get contact with business entities or business service providers,But so far there is no theory, no system, no way and no approach to differentiate these numerous different kinds of markers or to provide a solution to let users manipulate and control the various markers on the internet map to classify and clarify numerous markers displayed on the internet map after searching, especially in business bustling areas in the metropolis such as New York, London, Tokyo, Hong Kong, Singapore, Shanghai and Beijing etc. Furthermore, there are a lot of markers that have same latitude/same longitude and all markers overlapped each other and user cannot differentiate each others, for example, in one building with same latitude/same longitude on Google map, there are 10 different companies which each of them occupies a different room with different number or suite number in this building, all maps cannot distinguish each of these 10 companies, and on Google map, we can only see ONE marker which is appeared in last, If users want to know details of each company's information, no way.So the necessity and feasibility of classification and recognition of all these overlapped markers come to the stage and become possible.Our invention is to propose an approach and a methodology to solve these kind of issues, further more, we propose a theory to let user manipulate the markers on the internet map with some rules to follow.Our invention is generic and can be used in any internet map on both PC browsers (such as internet explorer, firefox etc) and smartphone for any internet maps such as Google MAp, Baidu Map, Gaode Map, QQ Map and Soho Map etc.Our invention is designed in Android system but can be applicable for Apple IOs system also.Our Android App successfully implements these methodology and concepts, we deployed and tested our Android app in all android smart phone successfully already.Our invention can let users do followings:1. Classify different kinds of markers on the internet map2. Manipulate all different kinds of markers on the internet map3. Manipulation Operations include:[1]. Add markers onto the internet map[2]. Remove markers from the internet map[3]. Distinguish all different markers on the internet map without any confusion[4]. Perform all these operation from any markers on the internet mapOur solution and methodology can let users pinpoint to the main targeted markers without diluting their focus and distracted from concerned target by other trivia, unimportant and unrelated markers, users can concentrate on specific area, special marker group, specific markers without any confusion and distraction by just simple operation invented here, so our invention provides a clear, concise and clean internet map instead of messed up ones.From now on we just use Lat or lat stands for Latitude and Lng or Ing stands for Longitude, ieLat/lat=Latitude;Lng/Ing=Longitude.We also use all markers for all icons/markers, we use maps for all internet maps .We will disclose our invention as follows step by step.

摘要： A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

摘要： A beamless mechanic-reversing long stroke pumping unit is provided for petroleum production in diverse types of oil fields. Its mechanic-reversing system consists of differentials, brakes, etc. With two differentials assembled together, taper gears inside them perform revolution and rotation, enabling the pumping unit to achieve direction change and speed change mechanically. The stroke length of the pumping unit can reach 8 meters or longer, and the adjustment process is more convenient than most, by merely tuning the position of the proximity switches. Abrasion of the chains typically caused due to resetting of a motor frequently during operation, is eliminated in this pumping unit. The pumping unit has more reliable operation performance, more convenient maintenance, lower costs, better energy saving effects, and can be applied in land oil fields, offshore oil fields, oil wells with low permeability, etc.
