Patent number: 10326330Abstract: Methods, apparatus, systems and articles of manufacture to implement cooling fans with selectively activated vibration modes are disclosed. An example cooling fan assembly includes a motor and a fan coupled to a shaft of the motor. The motor is to rotate the shaft in a first direction to cause the fan to move air. The motor is to rotate the shaft in a second direction to cause vibration from an eccentric mass coupled to the shaft.Type: GrantFiled: August 16, 2016Date of Patent: June 18, 2019Assignee: INTEL CORPORATIONInventors: Mikko Kursula, Kalle I.

Patent number: 10206021Abstract: A gas detection device includes an enclosure having an interior chamber, an audio loudspeaker in acoustic communication with the interior chamber of the enclosure, and a gas sensor configured to detect a gas within the interior chamber of the enclosure. The device may include a ventilation port configured to permit two-way gaseous communication between the interior chamber and an atmosphere external to the enclosure, where the atmosphere comprises the gas. The audio loudspeaker is configured to generate a pressure within the interior chamber. The pressure causes a portion of the external atmosphere to be drawn into the interior chamber via the ventilation port. The gas sensor may include an emitter and a receiver. The gas detection device can be integrated into a mobile electronic device, such as a smartphone or tablet computer.Type: GrantFiled: December 22, 2015Date of Patent: February 12, 2019Assignee: INTEL CORPORATIONInventors: Saku Lahti, Mikko S.

Patent number: 9553960Abstract: Systems and methods enhancing loudspeaker audio performance in thin devices, such as mobile computing platforms and/or communication handsets. In some embodiments, a laminate panel including a dielectric membrane and one or more conductive traces forming an inductive loop suitable wireless charging and/or near field communication (NFC) element is employed as a loudspeaker driven at audio frequencies. In some embodiments, the laminate panel is driven with one or more piezoelectric element. In some embodiments, the laminate panel is of a stiffness and mass to provide a frequency response distinct from that of integrated micro-speakers for a 2.1 audio solution with wider bandwidth than is possible with micro-speakers employing back-side cavities. In some embodiments, the frequency spectrum spanned by the laminate panel loudspeaker enables a tweeter design lacking back-side cavities for smaller device form factor.Type: GrantFiled: September 4, 2015Date of Patent: January 24, 2017Assignee: Intel CorporationInventor: Tapio Liusvaara
