Abstract: A semiconductor package includes a conductive pillar and a solder. The conductive pillar has a first sidewall and a second sidewall opposite to the first sidewall, wherein a height of the first sidewall is greater than a height of the second sidewall. The solder is disposed on and in direct contact with the conductive pillar, wherein the solder is hanging over the first sidewall and the second sidewall of conductive pillar.

Abstract: An pneumatic tool includes a front section, a rear section connected to and disposed behind the front section, a driving unit, and an air cylinder unit. The rear section includes a main body, a handle connected to the main body and adjacent to the front section, and an intake passage in fluid communication with the outside. The air cylinder unit includes a first cylinder mounted within the rear section, a second cylinder connected to the first cylinder, an extension portion extending into the handle, and an inclined intake channel having an inlet in fluid communication with intake passage, and an outlet in fluid communication with the first cylinder. The rotor unit is mounted rotatably within the first and second cylinders for activating the driving unit.

Abstract: A communication device adjusts its power level based on a desired quality of service and based on a data rate being used to transmit data. The communication device may comprise a processor, a transceiver, and a power source that provides a power level to the transceiver for transmitting data at a variable rate. The processor obtains a first value indicative of a number of transmission errors, computes a second value using the first value and based on the data rate, and determines whether the second value is below a threshold. Based on a comparison of the second value to said threshold, the processor initiates a change in the power level. Additionally or alternatively, the processor may adjust the power level based on whether a current frame contains an error, but not permitting the power level to be decreased to a level at which a signal-to-interference ratio falls below a threshold.

Abstract: A communication system and method for revising an updated target signal to interference ratio (SIR) ensure that the updated target SIR does not fall below a threshold target SIR that is required to ensure a specified minimum quality of service. In one aspect, the present invention provides a method for controlling an updated target signal to interference ratio in a communication system. In this method 180, an updated target signal to interference ratio is received (block 182). A threshold signal to interference ratio is established (block 184) and the updated target signal to interference ratio and the threshold signal to interference ratio are compared (block 186). The updated target signal to interference ratio is then set equal to the threshold signal to interference ratio if the updated target signal to interference ratio is less than the threshold signal to interference ratio (block 188).
