Title: Knitted glove with controlled stitch stretch capability
Inventor: THOMPSON ERIC
IPC: D04B1/28
Filed: 2005-07-14
Abstract: A knitted glove (200) made by creating each of the sections of the glove using a separate knitting course on a flat knitting machine providing variable stitch dimensions. Each of these sections provides its own designed stretch characteristics so that the glove fits tightly, yet provides flexibility and ease of movement. The variable stitch dimension is achieved by 1) varying the depth of penetration of a knitting needle into a fabric being knitted by a computer program, 2) adjusting the tension of yarn between a pinch roller and a knitting head by a mechanism controlled by a computer, and 3) casting off or picking up additional stitches in a course. The glove includes a plurality of finger components (210, 212, 214, 216, 218) made from at least ten separately knitted sections, two palm components (208, 206, 204), each of which is made from at least two separately knitted sections, and a wrist component (202) made from at least one knitted section.

IPC: H04B7/216
Filed: 2005-07-21
Abstract: A method and apparatus for optimizing the system capacity of an Orthogonal Frequency Division Multiplexing (OFDM) system that uses with Multiple-Input Multiple-Output (MIMO) antennas. In a receiver, a target quality of service (QoS) metric and reference data rate are set. The target QoS metric may be set to a predetermined value and/or may be adjusted dynamically with respect to packet error rate (PER) by a slow outer-loop control processor. The QoS of received signals are measured and compared to the target QoS. Depending on the comparison, the receiver generates a channel quality indicator (CQI) which is sent back to the transmitting transmitter. The CQI is a one or two bit indicator which indicates to the transmitter to disable, adjust or maintain data transmission rates of particular sub-carriers, groups of sub-carriers per transmit antenna, or groups of sub-carriers across all transmit antennas. At the transmitter, the transmitted data rate is disabled, adjusted or maintained. At the receiver, the target QoS metric and reference data rate are adjusted accordingly. This process is repeated for each data frame of each sub-carrier group.

Patent CA-2592799-A1 (CA)
Inventor: MATVEEV ANATOLY VLADIMIROVICH
IPC: C09K8/80
Filed: 2007-06-27
Abstract: This invention relates to oil and gas industry, more specifically, to the improvement of the hydraulic permeability of sand pumped into the fracture during formation hydraulic fracturing in the process of oil production. The positive result planned to be achieved by using the new proppant material is almost complete prevention of sand backflow, a significant increase in sand packing permeability and prevention of the production of fine grained proppant. This result is achieved due to the proppant material in the form of rigid elastic particles in the form of plates having a maximum to minimum dimension ratio of more than 5 made from a corrosion resistant material. The plates should not be deformable. The thickness of the particles can be 100 to 300 µm. The method of hydraulic fracturing wherein at least part of the fracture is filled with the proppant material in the form of rigid elastic plates or gratings having a maximum to minimum dimension ratio of more than 5 preferably made from stainless steel or low-carbon steel provides for the claimed positive result. The rest of the fracture can be filled with standard nonmetallic proppant/sand. The permeability of the fracture is thereby improved.

Title: Selection of a thresholding parameter for channel estimation
Inventor: STAMOULIS ANASTASIOS
IPC: H04L25/02
Filed: 2006-02-13
Abstract: Techniques for deriving a high quality channel estimate are described. A first channel impulse response estimate (CIRE) having multiple channel taps is derived, e.g., by filtering initial CIREs obtained from a received pilot. A  threshold parameter value is selected based on at least one criterion, which may relate to channel profile, operating SNR, number of channel taps, and so on. A second CIRE is derived by zeroing out selected ones of the channel taps in the first CIRE based on the threshold parameter value. The average energy of the channel taps may be determined, a threshold may be derived based on the average energy and the threshold parameter value, and channel taps with energy less than the threshold may be zeroed out. A memory may store threshold parameter values for different operating scenarios, and a stored value may be selected for use based on the current operating scenario.

Title: Provisioning of redundant sip proxy resources
Inventor: BOEHM MARKUS
IPC: H04L29/08
Filed: 2006-02-21
Abstract: The invention relates to a resolution of the address of an SIP proxy in an SIP  network, redundant SIP proxy resources being made available. In order to establish a connection in an SIP network, an SIP client typically transmits a request to a DNS server system to obtain an IP address so as to gain access to SIP proxy resources. According to the invention, the SIP proxy resources are provided in the form of a plurality of SIP proxy servers which are part of a peer-to-peer group. Messages are exchanged within the peer-to-peer group by means of a peer-to-peer protocol in order to communicate responsibilities for SIP domains or user-agent addresses. Responsibilities which are adjusted in case of disturbances or similar influences are defined within the peer-to-peer group. The IP address of the SIP proxy server responsible for the request of the SIP client is made available to the DNS server system such that the DNS  server system can forward said IP address to the SIP client so as to allow the SIP client to access the relevant SIP proxy server. The inventive way of making available SIP proxy resources requires little effort, is flexible, and makes it possible to quickly access redundant resources in case of a disturbance.
