  • Publication number: 20190320276
    Abstract: An improved method and system for varying an amount of mechanical coupling in a speakerphone is disclosed. Solutions and implementations provided vary the amount of mechanical coupling between one or more speakers and one or more microphones of the speakerphone to generate high-quality sounds. Implementations include receiving a signal for a first speaker, transforming the signal to send to a second speaker or actuator to generate either complementary or opposing vibration forces to those generated by the first speaker, and an accelerometer to measure the amount of vibration caused by the speaker and adjust the transformation applied to the signal to increase or decrease the amount of mechanical coupling, as needed.

  • Publication number: 20190320277
    Abstract: An improved method and system for varying an amount of mechanical coupling in a speakerphone is disclosed. Solutions and implementations provided vary the amount of mechanical coupling between one or more speakers and one or more microphones of the speakerphone to generate high-quality sounds. Implementations include receiving an input signal, sending a copy of the input signal to a first speaker, performing a signal transformation on the input signal to produce a transformed input signal, and transmitting the transformed input signal to a second speaker, where the first speaker generates a first vibration force in response to the input signal, and the second speaker generates a second vibration force in response to the transformed input signal, the second vibration force being in an opposite direction to that of the first vibration force and offsetting at least part of the first vibration force.

  • Patent number: 10076252
    Abstract: A wrist-worn pressure sensing device includes a pressure sensor. The wrist-worn pressure sensing device also includes a first strap that sets the position of the pressure sensor on a wearer's wrist and a second strap that engages with the first strap to adjust the overall length of the strap without moving the set position of the pressure sensor on the wearer's wrist.

  • Publication number: 20160287172
    Abstract: A wrist-worn device heart-monitoring device is presented. The wrist-worn heart-monitoring device includes a radial tonometer configured to output a pressure signal indicating a pulse pressure wave at a user's wrist, two or more electrodes configured to output an electrical signal indicating a user's heart has been commanded to contract, and a microphone configured to output an audio signal indicating a closing of a user's aortic valve. The wrist-worn heart-monitoring device further includes a pulse transit time monitor configured to calculate a pre-ejection period of the user's heart based on at least the pressure, electrical, and audio signals, and calculate a pulse transit time based on at least the pre-ejection period, the pressure signal, and the electrical signal.

  • Publication number: 20160287102
    Abstract: A system for transducing arterial pressure includes a one-piece flexible cap configured to fit around a flexible piezo-electric sensor that is configured to alter an internal resistance upon deflection. The flexible cap includes a deflection wall configured to deflect towards the flexible piezo-resistive sensor in proportion to pressure applied by the artery. A pressure-transducing medium is sealed between the one-piece flexible cap and the flexible piezo-resistive sensor, such that deflection of the deflection wall towards the flexible piezo-resistive sensor causes proportional deflection of the flexible piezo-resistive sensor.

  • Patent number: 9318904
    Abstract: A battery-charging device includes: a housing that is configurable from a first shape into at least a second shape; and a direct current-to-direct current battery charger disposed within the housing. The direct current-to-direct current battery charger is configured to convert direct current power, received from a source external to the battery charger, into a direct current source for supplying energy to a rechargeable battery that is electrically connected to the battery charger. The battery-charging device may further include a communication element configured to communicate, with a portable electronic device that includes the rechargeable battery, using a short-range communication technology.
