Abstract: Techniques for monitoring and predicting environmental operating conditions in a data center are provided. In one aspect, a method for real-time, three-dimensional analysis of environmental operating conditions in a data center includes the following steps. High spatial resolution three-dimensional measurements of one or more environmental variables in the data center made at a time t1 are obtained. Real-time measurements of the environmental variables in the data center made at a time t2, wherein t2 is later in time than t1, are obtained. The high spatial resolution three-dimensional measurements are combined with the real-time measurements to derive a model for the environmental variables in the data center at the time t2. The model is used to predict three-dimensional distributions of the environmental variables in the data center at the time t2. A base model can be created and used to derive the model for the data center at the time t2.

Abstract: The invention provides a heat-dissipating device and method. The heat-dissipating device comprises a transmitting device, at least a fin, and a fan. The transmitting device comprises a heat-dissipating channel and a passage. The passage comprises a converging intersection connecting to the heat-dissipating channel and the channel. The heat-dissipating method comprises dividing a air into a first airflow and a second airflow, and guiding the first airflow to pass through a fin while guiding the second airflow to converge into the first airflow and then passing through the fin together.

Abstract: A roller for an input device extends through a slot in a top housing and is supported by a cantilevered arm. The roller is attached at the end of the arm and rotates about a shaft mounted on the cantilevered arm. The cantilevered arm is attached proximate the rear of the top housing, and thus is free to flex when the roller is depressed. As a result, when pressure is applied to the roller, the roller depresses through the slot in the top housing independently from the buttons on the top housing. The cantilevered arm has a spring force to bias the roller upward, eliminating the need for a return spring (lift spring).
