  • Patent number: 10742730
    Abstract: A computer-implemented method includes sending a broadcast over a network requesting a response from other host computers on the network that are also communicatively paired with the input device, receiving a broadcasted response from a second host computer on the network indicating that it is communicatively paired with the input device, establishing a communicative connection with the second host computer via the network and automatically reestablishing the connection with the second host computer when the second host computer disconnects and reconnects to the network. In response to an edge-detect event, sending a control signal to switch the communicative pairing of the input device from the first host computer to the second host computer.

  • Patent number: 10719143
    Abstract: In some embodiments, a stylus device can be configured for use in an augmented/virtual (AR/VR) reality environment and can include a first portion and a second portion, where the first portion of the housing is substantially linear and can be configured to be held by a user's hand while the stylus device is in use. The first portion may include a tip configured to operate as an interface between the stylus device and objects within the AR/VR environment. The second portion of the housing may be non-linear and bent to traverse three dimensions including a section of the second portion that is bent longitudinally toward a line co-linear with the first portion of the housing. In some cases, the second portion of the housing may include a plurality of emitters or sensors configured for facilitating a tracking of the stylus device in three-dimensional space within the AR/VR environment.

  • Patent number: 10713185
    Abstract: Examples of techniques for wireless communication are presented. In some examples, an apparatus comprises a wireless transceiver and a hardware processor configured to perform: receiving, from a host device, a first indication of a host device clock signal, the apparatus and the host device being coupled via a wired interconnect; determining, based on the first indication and a second indication of an endpoint device clock signal, a phase relationship between the host device clock signal and the endpoint device clock signal; determining, based at least on the phase relationship, a first time for transmitting a sensor data request to a peripheral device of a computer; transmitting, using the wireless transceiver, the sensor data request to the peripheral device at the first time; receiving, from the peripheral device, the sensor data; and providing the sensor data to the host device via the wired interconnect as input data to the computer.

  • Patent number: 10692334
    Abstract: In some embodiments, a power supply in a doorbell system includes a boost rectifier circuit with a plurality of active devices arranged in a bridge topology that are configured to receive an AC input voltage, generate a DC output voltage by rectifying the AC input voltage, drive an electric load using the rectified DC voltage, and boost an amplitude of the AC input voltage. Two of the plurality of active devices in the boost rectifier circuit may be pulse driven and can control an operation of a mechanical or digital chime device. The chime device can include a solenoid and the boost rectifier circuit may utilize the solenoid as an energy storage element to facilitate the boosting of the amplitude of the AC input voltage. The boost rectifier circuit may boost the AC input voltage by at least a multiplication factor of two.

  • Patent number: 10694283
    Abstract: Aspects of the invention can include a teleconferencing system having a system housing, a speaker enclosure configured within the system housing, a speaker mounted to the speaker enclosure, and one or more damping cushions coupling the speaker enclosure to the system housing. The one or more damping cushions can suspend the speaker enclosure within the system housing such that the speaker enclosure is separated and mechanically isolated from the system housing by at least a minimum distance (e.g., 2 mm). In some cases, the one or more damping cushions provide the only structural coupling between the speaker enclosure and the system housing. The one or more damping cushions can be configured to dampen mechanical energy generated by the speaker thereby preventing at least a portion of the mechanical energy form coupling to the system housing via the one or more damping cushions.

  • Publication number: 20200150777
    Abstract: This disclosure describes various configurations for a keyboard having multiple key assemblies. Each of the key assemblies includes a keycap and a key stem supporting the keycap that includes a protrusion extending laterally therefrom. A first biasing member supports the key stem and is configured to provide a linear feedback response during actuation of the key assembly. A second biasing member is configured to engage the protrusion during actuation of the key assembly. The second biasing member has a user-configurable feedback response. In some embodiments, the first biasing member can be a compression spring and the second biasing member can be a torsion spring.

  • Patent number: 10651950
    Abstract: Embodiments of the invention are directed to control devices configured for use with computing devices. More specifically, the present invention relates to methods and devices for shortening wireless reconnection time by determining the presence of an object or body near a device. When the control device detects an object or body in proximity to the device, the control device may automatically establish a wireless connection with a host devices, such that when the control device receives any user interactions, the wireless connection has already been established, preventing loss of data.

  • Patent number: 10642467
    Abstract: In certain embodiments, an electronic input device includes a knob assembly defining an annular cavity and including a magnetically attractable armature. The electronic input device also includes a ratchet assembly disposed within the annular cavity and includes a ring magnet. The electronic input device includes a clutch mechanism that has a friction disc assembly, and an electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly prevents rotation of the ratchet assembly and a second position in which the ratchet assembly is free to rotate with the knob assembly. The ring magnet of the ratchet assembly interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.
