| 20090031659 | Evacuated Thermal Insulation Panel - A sealed vacuum thermal insulation panel having a thermal barrier that comprises a core made of thermal insulation material and two panel walls made of a barrier material substantially impermeable to atmospheric gases and water vapors. The two panel walls covers opposite sides of the core. The sealed panel further comprises at least one lateral strip of substantially impermeable to atmospheric gases and water vapor. The lateral strip is adapted to sealably enfold the edges of the obverse side of the two panel walls. Additionally, the sealed panel further comprises at least one sealing strip, each comprising sealing material. The sealing strip is adapted to sealably join the edges to the inner side of the lateral strip. | 02-05-2009 |
| 20090218247 | FLEXIBLE MOISTURE-BARRIER PACKAGES AND METHODS OF PRODUCING SAME - A flexible package for products sensitive to moisture, includes a front flexible sheet having moisture-barrier properties; and a back flexible sheet having moisture-barrier properties bonded along its peripheral edges to the peripheral edges of the front flexible sheet except for one edge to allow for the introduction of the product into the interior of the package and then the sealing of the package by bonding the unbonded edges. At least a section of the front flexible sheet having moisture-barrier properties is optically transparent such as to permit a moisture-indicator to be introduced with the product into the interior of the package before bonding the unbonded edges of the two sheets, and to be optically observed through the transparent section after the package has been sealed. Also described are various multi-layer constructions for the two flexible sheets, and methods of producing such packages to also include anti-static properties. | 09-03-2009 |

| 20110307770 | REDUCING A DEGREE OF A POLYNOMIAL IN A POLYNOMIAL DIVISION CALCULATION - An apparatus generally having a lookup table and a circuit is disclosed. The lookup table may be configured to store a plurality of results including remainders of divisions by a particular polynomial. The circuit may be configured to (i) parse a first polynomial into a plurality of data blocks and an end block, (ii) fetch a plurality of results from the lookup table by indexing the lookup table with each of the data blocks and (iii) generate a second polynomial by adding the results fetched from the lookup table to the end block. The second polynomial generally has a second degree that is lower that a first degree of the first polynomial. | 12-15-2011 |
| 20120102381 | SIMPLIFIED PARALLEL ADDRESS-GENERATION FOR INTERLEAVER - An apparatus including a first circuit and a second circuit. The first circuit may be configured to store a block of data values arranged in a first order. The first circuit may be further configured to present a plurality of the data values in parallel in response to a plurality of address signals, where the data values are presented in a second order. The second circuit may be configured to generate the plurality of address signals in response to a first signal, a second signal and a third signal. The second circuit generally includes an even number of address generators configured to generate the plurality of address signals in parallel. | 04-26-2012 |
| 20120157008 | METHOD FOR AVOIDING OVERFLOW OF MULTIPLICATION OF ROOTS-OF-UNITY BY USING OVERFLOW SAFE APPROXIMATED VALUES TABLE - An apparatus including a processor, a computer readable storage medium, and a lookup memory. The computer readable storage medium generally contains computer executable instruction that when executed by the processor perform operations involving fixed point multiplication. The lookup memory generally stores values used in the fixed point multiplication. The values stored in the lookup memory are approximated based upon a predetermined value to prevent overflow in the fixed point multiplication. | 06-21-2012 |
| 20120263246 | METHOD FOR REDUCING LATENCY ON LTE DL IMPLEMENTATION - An apparatus including a processor and a radio frequency (RF) interface. The processor may be configured to process downlink information such that a latency of the apparatus is determined by an amount of time involved in processing the downlink information to obtain a single orthogonal frequency division multiplexed (OFDM) symbol for presentation to the RF interface. | 10-18-2012 |

| 20120275374 | RATE MATCHING FOR WIDEBAND CODE DIVISION MULTIPLE ACCESS - Described embodiments provide a wideband code division multiple access (W-CDMA) system that employs a rate matching rule having a modified puncturing algorithm. The modified puncturing algorithm defines the input variables of the rate matching rule in a manner that provides for identification of relations between non-punctured data bit position addresses in the output data stream through an iterative process, from which absolute bit position addresses of non-punctured output bits might then be generated. A counter, in accordance with instruction generated by a processor or state machine, for example, might implement the modified puncturing algorithm on an input string of bits to provide an output string of bits based on the absolute bit position addresses of non-punctured output bits, thereby providing for rate matching in the communications channel. | 11-01-2012 |

| 20090071478 | VENTILATOR - A ventilator to replace or supplement a patient's breathing includes a control valve in the form of a proportional obstacle valve (POV) to provide improved air flow control and ventilator operation reliability. The POV includes an inlet, an outlet and a bypass. A stopcock controlled by a stepper motor directs the flow of air through the bypass and outlet permitting the turbine to operate a constant RPM yet allowing control of the airflow to a patient. The ventilator also includes inhalation and exhalation valve assemblies which improve air flow control and are easy to manufacture. The inhalation valve includes an orifice disk to allow pressure sensors to move accurately measure air flow. The exhalation valve assembly includes wings to reduce turbulence and enhance sensor accuracy. The exhalation valve assembly is arranged to have warm air from cooling the turbine blow over the assembly to reduce the possibility of condensation forming therein. The ventilator also includes an improved power supply with redundant sources of power. | 03-19-2009 |
