摘要： Stylus orientation detection is disclosed. In an example, the orientation of a stylus relative to a contacting surface, e.g., a touch panel, can be detected by detecting a capacitance at one or more locations on the stylus relative to the surface, and then using the capacitance(s) to determine the orientation of the stylus relative to the surface. In another example, the orientation of a stylus relative to a contacting surface, e.g., a touch panel, can be detected by first detecting the orientation of the stylus relative to a reference, detecting the orientation of the contacting surface relative to the reference, and then calculating the orientation of the stylus relative to the contacting surface using the two detected orientations.

摘要： Methods and systems for efficiently embedding information in a keyboard membrane. Information can be embedded in the keyboard membrane by integrating an information embedding circuit with a switch matrix used to identify location of a key press event. The information is embedded by either hardwiring a column to a selected row, or a row to a selected column. In order to access the embedded information, the row (column) is asserted resulting in the hardwired column (row) to also be asserted. The identification of the asserted column (row) is used to point to the embedded information.

摘要： Some embodiments provide a system that facilitates use of an electronic device. The electronic device may be a keyboard, a mouse, a trackpad, a remote control, a wireless phone, a toy, a battery charger, and/or a camera. During operation, the system measures a loaded voltage of a calibrated voltage source connected to the electronic device. To measure the loaded voltage, the calibrated voltage source is connected to a known load in the electronic device, and a voltage measurement for the calibrated voltage source is obtained using an analog-to-digital converter (ADC) in the electronic device.

The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance can be on the order of 1 meter or so. The NFMR power supply is used to tune a transmitter in order to maintain a high Q factor.
