摘要:
In certain aspects, a method for temperature monitoring comprises receiving temperature readings from a plurality of temperature sensors on a chip, and determining an average or a sum of the temperature readings from the temperature sensors. The sum may be a weighted sum of the temperature readings. The method also comprises computing a temperature at a location on the chip based on the average or sum of the temperature readings. The location may be located at approximately a centroid of the locations of the temperature sensors, an estimated hotspot location on the chip, or another location on the chip.

A baffle assembly directing air flow for cooling electrical components by providing three-dimensional separation of the air flow for individual cooling air streams. The assembly includes a first baffle portion composed of a conduit of material and a second baffle portion composed of a sheet of material and coupled to the first baffle portion. The first baffle portion directs a first portion of the air flow to a first electrical component for cooling the first electrical component and directs a second portion of the air flow around the first electrical component to maintain a cool air stream. The second baffle portion directs the first portion of the air flow around a second electrical component as waste heat and directs the second portion of the air flow to the second electrical component for cooling the second electrical component.

Techniques and apparatus for controlling the distribution of power (e.g., current) and the temperature to individually accessible compartments enclosing subsystems of a personal communication structure (PCS) is described. The PCS includes a power distribution and temperature controller subsystem, including thermal sensors adapted to generate and transmit temperature measurement data to the temperature controller, which controls fans/blowers. The power distribution subsystem senses and controls the current delivered to the individually accessible compartments.

Various embodiments of methods and systems for modem management in a portable computing device are disclosed. An exemplary method recognizes an input of a key performance indicator ("KPI") from a plurality of performance indicators. Based on the key performance indicator either manually by a user or automatically based on system status information, the exemplary method determines a particular modem management and control strategy designed to optimize performance of the modem based on the key performance indicator. The determined modem management and control strategy is implemented to cause adjustment of a modem performance level such that the key performance indicator is optimized. Exemplary KPIs include, lower device temperature, maximization of the percentage of time that the modem is operating at a maximum advertised LTE speed, maximization of the average data throughput, maximization of battery life, and minimizing LTE speed transitions over time.
