摘要： Aspects of the invention include a computer peripheral device comprising an input element that operates based on a performance characteristic, an electropermanent magnet (EPM) assembly including a permanent magnet configured to generate a magnetic field and a magnetizing assembly configured to set an intensity of the magnetic field generated by the permanent magnet, and a magnetorheological (MR) material coupled to the input element. The MR material has a viscosity that changes based on the magnetic field and affects the performance characteristic of the input element.

摘要： A system comprising a host device configured to request a haptic effect from a peripheral device, the peripheral device configured to perform operations including: receiving a request from the host device to generate a haptic effect at a specified intensity; determining an operating range of a motor configured to generate the haptic effect on the peripheral device, where the operating range defines a maximum force that the motor can generate in a linear region of operation, and the operating range changes based on a temperature of the motor; scaling the specified intensity of the haptic effect based on the determined operating range of the motor; and controlling the operation of the motor to generate the haptic effect at the scaled specified intensity, where the scaling is performed by the peripheral device.

摘要： Described herein are methods and systems for connecting via a cable a USB host and USB device over distances equal to greater than 50 meters. The methods and systems include having the host and device each send a pilot signal over the cable and the host and device, each detecting that the received pilot signal is valid. After confirming the validity of the pilot signals, the host begins standard USB protocols with the device. The system and methods also allow for the insertion of a power over Ethernet device into the cable to provide power to a remote USB device. In some embodiments, only the D+ and D− lines are used allowing multiple independent USB connections over the cable.

摘要： Embodiments of the disclosure provided herein can be used to improve the control, selection and transmission of data to a remote video conferencing environment, by use of a plurality of wired or wirelessly connected electronic devices. In one example, the transmission of data from a local environment can be improved by switching the source of visual inputs (e.g., cameras or display of an electronic device, such as laptop) and/or audio inputs (e.g., microphones) to the one or more appropriate visual and audio sources available within the local environment. The most appropriate visual and audio sources can be the sources that provide the participants in the remote environment the most relevant data giving the remote users the best understanding of the current activities in the local environment.

摘要： A method of operating a computer mouse includes receiving electromagnetic (EM) radiation emitted from a source external to the computer mouse, the received EM radiation induces noise within one or more bands of noise frequencies and an image sensor circuit of the computer mouse generates erroneous movement detection signals in response to an operating frequency of the image sensor circuit being within the one or more bands of noise frequencies. The method further includes determining the operating frequency of the image sensor circuit, comparing the operating frequency to a target frequency, wherein the target frequency is outside of the one or more bands of noise frequencies, and tuning the operating frequency of the image sensor circuit towards the target frequency.
