Abstract: Example field replaceable fan assemblies for peripheral processing units and related systems and methods are disclosed. An example apparatus includes a temperature sensor; a fan having a base; at least one memory; machine readable instructions; and processor circuitry to execute operations corresponding to the machine readable instructions to determine a first temperature based on an output of the temperature sensor; and cause the base of the fan to move based on the first temperature.

Abstract: Methods and apparatus to implement microphones in thin form factor electronic devices are disclosed. An electronic device includes a chassis having an exterior surface and an interior surface. The chassis includes a plurality of holes extending through the chassis. The plurality of holes are within a 1 mm diameter circular area of the chassis. The electronic device further includes a microphone coupled to the interior surface of the chassis adjacent the circular area of the chassis.

Abstract: Related fields include portable device assemblies, and in particular, techniques to extract back volume for speakers in thin unibody devices. A system consistent with the present disclosure comprises a unibody structure to support internal components of an electronics device. The unibody structure has a thickness of less than 7 mm. The chamber region is to facilitate a back volume of at least 0.77 cubic centimeters. The system further included a speaker that is fitted within a speaker cavity.

Abstract: A temperature sensing system for use in a computer disc drive comprises a themoelectric sensor having an output sensor voltage which is variable as a function of temperature, an interface circuit adapted to receive the output sensor voltage from the thermoelectric sensor and adapted to generate a scaled and level-shifted analog output voltage signal, and an analog-to-digital converter circuit adapted to receive the analog output signal voltage from the interface circuit and convert the analog output signal voltage into a digital signal which is compared to various defined thresholds.
