A computer accessory including a base, a strap and an attachment mechanism. The base includes a mouse pad portion. The strap is attachable to the base, and the strap is used to secure the attachment mechanism.. The attachment mechanism is to removably attach the device to a user's clothing, belt or fitment. A barrier may also extend at the edge of the mouse pad portion. Alternatively, the base includes a touch pad portion or track pad portion for use as a computer mouse, or the base includes a rollerball mouse portion for use as a computer mouse. The user may thus be able to use the computer accessory in place of a traditional computer mouse. Advantages provided by the computer accessory include pain and stress relief, ease of alternating between mouse use and keyboard use, portability, ease of switching between the left and right hands, and use in a variety of orientations that can cater to the user's personal needs.

The ergonomically optimized self-stabilizing leg mounted mouse pad with integrated mouse storage holster provides a stable working surface area designed specifically for operating a common wireless computer mouse while resting the mouse pad discussed here on other than flat firm surfaces. Such alternative platforms upon which this device can be used effectively would include a user's thigh, the arm of a couch or an automobile's center console. The design features are purposefully engineered to ensure that the invention is self stabilizing on other than a flat firm surface through the use of a contact surface that is a curvilinear concavity with a camphered surface architecture that maximizes the advantage of the weight of the device coupled with the tacky characteristics of the material from which the device is constructed. The device is stable in its intended use without the use of supplemental attachments to secure or stabilize the device.

An accessory device for use with an electronic user apparatus is disclosed. The electronic user apparatus includes at least one capacitive sensor for detection of at least one control object with respect to a control surface, and at least one apparatus guard placed at an alternating guard potential (V.sub.G), different from a ground potential of the at least one control object, and identical to a potential of the capacitive sensor. The accessory device includes at least one accessory guard capable of being set to the alternating guard potential (V.sub.G) by coupling with the electronic user apparatus.

An apparatus including a removable modular insert disposed within a housing of a host device, the housing including one or more magnets, and one or more conductive contacts disposed on the removable modular insert to magnetically couple to the one or more magnets and secure the modular insert within the housing of the host device, and electrically couple the modular insert to the host device. A conductive coil can be coupled to the modular insert to electromagnetically receive power from a base device having a surface, where the host device moves and operates along the surface of the base device. The apparatus can include a communication device and a processor to control the communication device for communication between the modular insert and the host device, and control operation of the conductive coil. The communication device further controls the electromagnetic coupling between the modular insert and the base device.

A charging board with an adjustable charging position and a charging method thereof are provided. The charging board includes a control circuit, an indicating circuit and a board body. The board body has a coil accommodating portion, and the coil accommodating portion has a transmitting coil. The transmitting coil can be adjusted in the coil accommodating portion. The control circuit detects the storage position of the transmitting coil, and controls the indicating circuit to output a corresponding indication signal according to the detection result. Thereby, the charging board can be used by a user to adjust the charging position.

A system including a first device with a surface and an identification feature that includes or encodes machine-readable data related to the surface, and a second device including a sensor and one or more processors coupled to the sensor that are configured to determine a relative displacement of the second device as it is moved along the surface of the first device. The second device receives the machine-readable data related to the surface from the identification features from the first device and configures the second device to determine the relative displacement along the surface differently (e.g., improves displacement tracking) based on the machine-readable data related to the surface.

In one example in accordance with the present disclosure, a user interface system is described. The system includes a user interface surface. A strike sensor disposed on an underside of the user interface surface detects a strike to the user interface surface and distinguishes between movement of the user interface device along the user interface surface and a strike to the user interface surface. A haptic feedback device generates haptic feedback responsive to a detected strike.

A method and system configured to receive a first report from a computer peripheral device, determine a trajectory of the computer peripheral device based on the first report, and determine a predicted activity level of the computer peripheral device based on the first report. The method and system can be further configured to compare the predicted activity level of the computer peripheral device with a baseline activity level and in response to determining that the predicted activity level of the computer peripheral device exceeds the baseline activity level, generate and send a first command to the computer peripheral device configured to cause the computer peripheral device to send a subsequent report of aggregated movement data at a first report rate.

Embodiments describe a wireless charging system including an accessory device and a host device. The host device can include a housing having a charging surface and power transmitting circuitry coupled to a power source. The power transmitting circuitry can include an inductive transmitter coil configured to receive a first power and generate magnetic field, an amplifier coupled to the inductive transmitter coil and configured to output the first power to the inductive transmitter coil, an output sensor coupled to the inductive transmitter coil and configured to measure the first power to the inductive transmitter coil, and a power tracking controller coupled to the sensor probe. The power tracking controller can be configured to receive measurement of the first power, and generate a control signal based on the measured first power to modify an output impedance of the amplifier to output a second power different from the first power.
