摘要:
A method for Hybrid Automatic Repeat Request (HARQ) combination is disclosed. The method includes that: externally configured parameters relevant to HARQ combination are received, and an identifier ddr2switch of DDR2 switching is calculated to acquire addresses involved before and after the HARQ combination; it is determined, according to the parameters and the addresses involved before and after the HARQ combination, whether the HARQ combination is needed to be performed; and when it is determined that the HARQ combination is needed to be performed, data in a DDR2 are read and stored into a first data cache random access memory RAMA; and a HARQ combination calculation is performed, and the calculation result is stored into a second data cache random access memory RAMB. A device for HARQ combination is further disclosed. The technical solutions provided in the disclosure are based on a latest interference cancellation algorithm, greatly increase the success probability of decoding, saves the storage space of a DDR2 and improves the reading or writing efficiency.

摘要:
A security system tag. The security system tag includes a housing. The security system tag further includes an electronic article surveillance, EAS, element in which the EAS element is arranged to emit a detectable signal when introduced to an interrogation signal. The security system tag further includes a metal element in which the metal element is adapted to be heated. The security system tag further includes a first reversible adhesive proximate the metal element in which at least a portion of the first reversible adhesive de-bonds when thermally affected by the metal element when the metal element is heated.

An integrated semiconductor heating assembly includes a semiconductor substrate, a chamber formed therein, and an exit port in fluid communication with the chamber, allowing fluid to exit the chamber in response to heating the chamber. The integrated heating assembly includes a first heating element adjacent the chamber, which can generate heat above a selected threshold and bias fluid in the chamber toward the exit port. A second heating element is positioned adjacent the exit port to generate heat above a selected threshold, facilitating movement of the fluid through the exit port away from the chamber. Addition of the second heating element reduces the amount of heat emitted per heating element and minimizes thickness of a heat absorption material toward an open end of the exit port. Since such material is expensive, this reduces the manufacturing cost and retail price of the assembly while improving efficiency and longevity thereof.
摘要:
A semiconductor device includes a semiconductor material substrate, an opto-electric component formed on the substrate, and a first transparent layer formed on an upper surface of the substrate over the component, the layer having a planar upper surface with a cavity formed therein. The first transparent layer has a selected thickness and a first index of refraction. The semiconductor device further includes a lens having a second index of refraction, the lens being formed in the cavity by flowing a flowable dielectric over the substrate. An upper surface of the lens and the upper surface of the transparent layer may be coplanar, or alternatively, they may lie in separate planes. The semiconductor device may also include a second transparent layer formed over the first layer and lens, as a passivation layer.

摘要:
Connection between optical fibers and optical components within a semiconductor substrate. A lens is created at the front of a semiconductor substrate. A tapered hole is created in the back of the substrate exposing part or all of the surface of the lens. An optical component is formed or affixed at the front surface of the substrate. A volume of transparent adhesive is placed in the hole, followed by an optical fiber, which is thus coupled to the surface of the lens. A light guide is created on the front of the substrate overlying the lens to direct optical signals between the optical fiber inserted in the tapered hole and the optical component on the surface of the substrate.
