Abstract: A method comprises receiving rotation data from a sensor configured to detect a rotation of a rotary device on a computer peripheral device, calculating a predicted rotational state of the rotary device after a period of time based on the rotation data and physical characteristics of the rotary device, and receiving updated rotation data from the sensor after the period of time. The method further includes calculating a difference between the predicted rotational state and an instant rotational state of the rotary device, the instant rotational state based on the updated rotation data and determining that a touch event has occurred on the rotary device when the calculated difference between the predicted rotational state and the instant rotational state is greater than a difference threshold value. The rotation data can include at least one of angular position data, angular velocity data, or angular acceleration data.

Abstract: A keyboard system comprises a key structure including a key switch with a lighting element and phototransistor, and one or more processors that drive the lighting element for a first pulse duration. The output of the phototransistor is determined at the end of the first pulse duration, wherein the key structure is determined to be pressed when the output is below a first output value at an end of the first pulse duration, and unpressed when the output of the phototransistor is above a second output value at the end of the first pulse duration. A fall-time of the output during the first pulse duration is determined and the first pulse duration is calibrated to a second pulse duration when the fall time less than the first pulse duration, the second pulse duration being greater than the fall time and less than the first pulse duration.

Abstract: A method comprising receiving a first control signal indicating that a first key on a keyboard is being pressed, the first key functionally assigned as a (logical) modifier; sending a first make command indicating that the modifier is active; receiving a second control signal indicating that a second key on the keyboard is contemporaneously being pressed, the second key functionally assigned as a non-modifier, alphanumeric character; accessing a key remapping database stored on the keyboard that includes key triggers and remapped key targets; in response to determining that the combination of the first key and second keys are included as a key trigger in the key remapping database: sending a first break command indicating that the modifier is inactive; and sending a second make command corresponding to a key target of the remapping database that is associated with the combination of the first and second keys being pressed.

Abstract: In some embodiments, a computer mouse includes a housing, a depressible keyplate, and a haptic element coupled to a bottom surface of the depressible keyplate. The haptic element can be configured to operate in a plurality of modes of operation including a first mode and a second mode. In the first mode of operation, the haptic element can generate a haptic output that statically and unidirectionally deflects and holds the haptic element and coupled keyplate at a deflection distance. In the second mode of operation, the haptic element can generate a second haptic output that bidirectionally deflects the haptic element relative to the deflection distance thereby generating a vibrational feedback that is superimposed on the unidirectional deflection at the deflection distance. In some aspects, the haptic element is a piezoelectric device and the control signal is a voltage applied to the haptic element.

Abstract: A computer mouse includes a housing, one or more processors disposed in the housing, and a trackball and a scroll bar configured on a top side of the housing and controlled by the one or more processors. The scroll bar has a width that is at least twice a diameter of the scroll bar. The housing has a triangular shape defined by three corners and three sides, each of the three sides coupled to a corresponding two of the three corners. A center of the trackball is configured at a location between a center point of the top side of the housing and a first corner of the three corners. The scroll bar can be configured between the center point of the top side of the housing and a first side of the three sides, the first side being opposite the first corner of the three corners.

Abstract: A computer-implemented method comprising: receiving, by one or more processors of a keyboard device from a host computing device communicatively coupled thereto, a request to switch to a first key input profile for a plurality of keys on the keyboard device; determining whether the first key input profile is locally stored on the keyboard device in a persistent memory; in response to determining that the first key input profile is stored in persistent memory, programming the plurality of keys using the first key input profile stored in the persistent memory; and in response to determining that the first key input profile is not stored in persistent memory: writing the first key input profile to persistent memory when the first key input profile is at least n bytes in size and programming the plurality of keys using the first key input profile.

Abstract: A method of authorizing a computer mouse to perform a particular action may include receiving, by a network device, a request associated with a particular action to be performed by a computer mouse. The request may be digitally signed using a private device key of the computer mouse. The method may include validating, by the network device, the digitally signed request using a public device key previously provided by the computer mouse. The method may include generating a response to the request. The response may indicate whether the computer mouse is authorized to perform the particular action associated with the trusted request. The method may include sending the response to a client device associated with the computer mouse.

Abstract: An integrated case and stand for holding at least two computer peripherals and providing a stand for a portable computing device. The integrated case and stand has a case body which includes a first compartment configured to hold a first computer peripheral and a second compartment configured to hold a second computer peripheral.
