A method of making polyolefin with a target melt flow index and melt flow rate is disclosed. The method polymerizes one or more olefinic monomers in a single reactor containing a bicomponent catalyst system. The catalyst system includes a first catalyst component and a second catalyst component each characterized by a catalyst productivity and a chain-transfer-agent response. The single reactor has a chain-transfer-agent concentration and a temperature. The productivity of the second catalyst component is substantially different temperature dependent than that of the first catalyst component. The chain-transfer-agent response of the second catalyst component is substantially different sensitive than that of the first catalyst component. The temperature of the reactor is adjusted so that the melt flow ratio approaches the target value. The chain transfer agent concentration in the reactor is adjusted so that the melt index approaches the target value.

A client computer is connected via a network to an anti-virus server. A signal from the anti-virus server notifies the client computer that an anti-virus needs to be immediately downloaded from the anti-virus server. The client computer disengages from the network, and re-establishes a link with only the trusted anti-virus server. The anti-virus fix is installed, the client computer re-booted, and the client computer is then allowed to reconnect to the full network. If the client's primary operating system (OS) is infected, a secondary OS in the client computer performs the anti-virus download and execution. The disengagement from the network is performed by applying a filter in a network interface card (NIC) driver by the primary OS, the secondary OS, a service processor (SP), or by a virtual machine manager (VMM), depending on which is available at the client computer.

A packaging film includes a heat sealable layer coated with one or more antifogging agents disposed in a binder, an antiblocking agent, and no more than about 800 ppm slip agent. The heat sealable layer includes a polymer that includes mer units derived from ethylene while the binder includes a polymer that includes mer units derived from an ester of (meth)acrylic acid and/or vinyl acetate monomers. The antiblocking agent can be in any layer of the film where it provides the desired effect. Such a film, as well as packages made therefrom, can be used to package a variety of products, having particular utility with respect to moist products.

The present invention comprises methods and apparatus for determining the rate at which data was encoded when such data is received at a receiver. According to the present invention, the rate is determined by computing, for a plurality of possible rates, a final test statistic based on a plurality of measures. The final test statistics are compared and based upon certain selection criteria (for example, without limiting the foregoing, which final test statistic corresponds the highest value), the rate is selected. In the preferred embodiment, the measures comprise statistics based on the cyclical redundancy check, Viterbi metrics, re-encoded symbol error rate, and distance to next largest Viterbi metric.

When a mobile communication unit (e.g. a cellular telephone) is powered up, the unit must lock on to a local base station, or "acquire" a base station signal, to enable the user to send and receive calls. To lock on a local base station, the mobile unit must determine the delay at which the base station is sending the pseudo random (PN) code. This process is called the "acquisition." The current art of acquiring a base station involves searching the possible code phases, or delays, one by one until the first signal is found. However, multiple base stations may be available to the mobile user, and the first found pilot signal may not be the strongest and may not be from the nearest base station. The present invention discloses a method and apparatus for searching all possible PN code phases and selecting the strongest phase instead of selecting the first phase. The method comprises of steps of testing all PN code delays, storing the delay and its corresponding signal strength of the delays having a signal strength greater than a threshold, and finally selecting the delay with the strongest signal among the stored delays.

A portable basketball goal assembly that includes a rim attached to a backboard bracket. The backboard bracket is attached to a basketball backboard. The rim is pivotal in a direction towards the basketball backboard. The backboard is attached to one end of a shaft that contains foldable elements. The other end of the shaft is pivotally attached to the rear end of a base. A shaft support element has one end pivotally attached to the front end of the base. The other end of the shaft support element is removably attached to the shaft. The shaft and the shaft support element can be folded towards the base to allow storage and portability of the basketball goal. The base includes one or more wheels along its front edge allowing for transportability of the folded assembly. The basketball goal assembly can be stored in either a horizontal position parallel to the ground, or a vertical position perpendicular to the ground.

A grill has a base that supports a grill body. A right and left lid are hingedly affixed to the grill body. The lids interconnect to ensure that they open and close together. A plurality of vents is defined by an upper surface of the lids. A shelf having a right portion, a left portion, and a rear portion substantially surrounds the grill body except for the operator position to the front of the grill body. The shelf and the right side of the grill body define a right retracting space. The shelf and the left side of the grill body define a left retracting space. The lids pivot outwards into the left and right retracting spaces to retracted positions wherein the uppermost portions of the lids and the uppermost surface of the grill body are substantially even with or below an upper surface of said shelf.

A system and method for anticipating consumer behavior and determining transaction incentives for influencing consumer behavior comprises a computer system and associated database for determining cross time correlations between transaction behavior, for applying the function derived from the correlations to consumer records to predict future consumer behavior, and for deciding on transaction incentives to offer the consumers based upon their predicted behavior.
