440 results about "Puncturing" patented technology

In coding theory, puncturing is the process of removing some of the parity bits after encoding with an error-correction code. This has the same effect as encoding with an error-correction code with a higher rate, or less redundancy. However, with puncturing the same decoder can be used regardless of how many bits have been punctured, thus puncturing considerably increases the flexibility of the system without significantly increasing its complexity.

Apparatus and method for incision-free vaginal prolapse repair

InactiveUS20050199249A1Suture equipmentsBed wetting preventionVaginal ProlapsesDistressing
In a preferred application, e.g., the repair of vaginal prolapse after relocation of the vagina and any organs displaced by the prolapse, corrective surgery is initiated by applying a hollow tubular element, formed to forcibly insert a barbed anchor attached to a distal end of a first length of suture, without any incision, from the inside of the vagina through the vaginal wall (the supported tissue) into selected support tissue within a patient's pelvis. This involves puncturing and thus locally severe physical distressing of both the supported tissue and the support tissue. The barbed anchor is left in the support tissue as the tubular element is then withdrawn from the support tissue and out of the vagina, leaving the proximate end portion of the suture extending through the vaginal wall into the vagina. A second such anchor, with a second length of suture attached thereto, is similarly inserted adjacent to the first anchor. The proximate end portions of the sutures are tied to each other inside the vagina, to thereby secure the vaginal wall to the support tissue with corresponding punctures formed in each by the insertions of the two anchors being thereby held in respective, precisely aligned, intimate contact during healing. This results in a pair of fused scars that cooperate to permanently bond the vaginal wall locally to the support tissue. If the sutures and/or the anchors are made of absorbable material they will all eventually disappear and the fused scars will provide the permanent bonding. If the anchors are made of non-absorbable material they may remain where located. A plurality of such paired fused-scar bonds may be generated, at the surgeon's discretion, to ensure adequate support for the repaired vagina. The apparatus and method can be readily adapted to similarly effect deliberate, local, beneficial bonding between other adjacent living tissues in a patient.

Puncturing System For Collecting Body Fluid Sample

The invention relates to a microsampler puncturing system for collecting a body fluid from a body part, comprising a sample collection unit having a piercing element, and a puncturing instrument having a drive, by which a sample collection unit is movable on a movement path for piercing the piercing element into the skin of the body part and withdraw it again by means of a piercing and retraction movement, a setting device for setting the puncturing depth of the piercing wound to be generated, and a control device for controlling the piercing and retraction movement having the following sequentially executed movement phases: a forward phase (V), in which the piercing element is pierced up to a defined puncturing depth (dm), a retraction phase (R1), in which the piercing element is partially retracted by a retraction distance (Δd) and is decelerated toward the end of the retraction phase (R1), so that it remains projecting into the skin at a defined residual puncturing depth (dr), and a collecting phase (S), in which the piercing element projects into the skin and a body fluid sample is absorbed by the sample collection unit. The setting device is adapted for the defined puncturing depth is settable independently of the chronological mean <dr> of the defined residual puncturing depth (dr), with reference to the collecting phase.

Trilaminar co-extrusion thermal contraction resin film, manufacturing method and application method thereof

The invention discloses a three-layer coextrusion heat shrinkage resin film, a production method and an application method. The-three layer coextrusion heat shrinkage resin film is produced by taking PE(LDPE, HPPE, LLDPE, mPE), EVA, PP, PA and EVOH resins as the main materials which are matched with a functional master batch and adopting a production method of one-step huffing. The largest transverse and longitudinal shrinking rates of the product can reach 60 percent and 85 percent; the largest shrinking force of the product can reach 2.0N/cm. The shrinking rate and the shrinking force of the product can be controlled and adjusted by controlling various technical parameters to lead a package to be firm and endurable. The packaged objects are pertinently led to reach the anti-rust, anti static, illumination-resistance, anti-aging, anti-puncturing, anti-low-temperature, anti-isolation, anti-bacteria and anti-degradation effects and the like by adjusting the material composition and mixture ratio of each layer. The three-layer coextrusion heat shrinkage resin film is used for replacing the traditional paper box wrappage to reduce the packaging cost. The mechanical properties are good, the pertinence is strong, the materials are saved; when the three-layer coextrusion heat shrinkage resin film is used, the shrinking temperature is low, the power is saved and the packaging cost is saved, thus effectively reducing the production cost and having extremely high application value.

Method of rate matching for link adaptation and code space management

A method of symbol combining and incremental redundancy for link adaptation and code space management was proposed. In order to reduce constraints on the Walsh codes allocation, MCS level change, as well as frame duration change for the initial transmission and re-transmissions, a “rate matching” stage is proposed between the Turbo encoder and block interleaver on the transmitter. In the initial transmission, the Turbo encoded symbols are interleaved with or without any puncturing or repeating (i.e. puncture/repeat factor is set to 1). The coded symbols are also stored in the memory for possible retransmissions. In the re-transmission, the transmitter first determines the number of Walsh codes available for this user and MCS level and frame duration according to the C/I feedback values from MS. The stored coded symbols are then punctured or repeated according to “rate matching factors”. On the receiver side, “rate matching factors” can be derived from the number of code channels, MCS level and frame duration of current re-transmissions and initial transmission. Then, de-puncturing/de-repeating is performed before coded symbol combining. A similar rate matching based IR/symbol combining scheme can be used to design different IR using different rate matching algorithms. It has low implementation complexity and is easily made backward compatible.

Method for puncturing a low density parity check code

A method for puncturing a Low Density Parity Check (LDPC). The method includes a) setting a codeword length and the total number of bit nodes to be punctured; b) selecting a check node (or check nodes) with highest priority excluding check nodes completely checked in a current round; c) selecting a bit node (or bit nodes) with a highest priority excluding bit nodes completely checked among bit nodes connected to the selected check node (or check nodes); d) determining whether the selected bit node is a bit node to be punctured, that is, it is not systematic, not set by a puncturing prohibition flag; e) puncturing an associated bit node if the selected bit node is the bit node to be punctured, setting unpunctured bit nodes connected to the selected check node by a puncturing prohibition flag, decreasing the number of remained bit nodes to be punctured by 1 and increasing the number of connected punctured node of associated check node by 1; f) determining whether the number of remaining bits to be punctured is greater than 0; and g) returning to step b) if the number of remaining bits to be punctured is greater than 0, and ending a puncturing process if the number of remaining bits to be punctured is not greater than 0.

Universal dispenser for dispensing of laundry additives during automatic machine laundering of fabrics

Disclosed are systems, methods, devices and kits for dispensing laundry additive materials into the drum of an automatic washing machine as that machine is used to carry out a fabric laundering operation. To bring about such dispensing of additives, a lidded housing structure is placed within the drum of an automatic washing machine, an insert, containing one or more laundry additives in each compartment, is placed within the lidded housing structure, the lid is closed and the machine is run through the several stages of its laundering cycle. Selectively actuatable puncturing element are provided to optionally open at least one compartment of the insert upon closing of the housing structure lid, thereby dispensing the contents of that opened compartment into the washing machine drum as wash additive materials and/or to open one or more compartments of the insert later in the laundering cycle to dispense contents of those compartments into the washing machine drum as rinse additive materials. The selectively actuatable puncturing element being activated by centrifugal force arising during the spin cycle of the laundering operation. In a multiple rinse cycle laundering operation, selectively actuatable puncturing element has a track and cam that allows for the dispensing of additives into the desired rinse cycle.
