Abstract: A cordless appliance includes a blender having a base unit with a housing and an upwardly opening upper cavity. A drive connection is positioned within the upwardly opening upper cavity. The housing further includes a battery-receiving cavity that is configured to receive a removable battery. A motor is disposed within the housing of the base unit it is contemplated to be powered by the removable battery. A blender jar includes an upper collar in an interior cavity. A first lid assembly is configured to be coupled to the upper collar of the blender jar and includes a blade assembly and a drive connecting member. A second lid assembly includes a cap member removably received on an open aperture of the second lid assembly. The first and second lid assemblies are configured for limited rotation with respect to the blender jar for engagement of the same.

Abstract: A wireless power transmitter can include a wireless power transfer coil designed to magnetically couple with a corresponding coil in a wireless power receiver to facilitate wireless power transfer from the wireless power transmitter to the wireless power receiver, a power converter configured to drive the wireless power transfer coil, and control and communications circuitry coupled to the wireless power transfer coil and the power converter. The control and communications circuitry can be configured to operate the power converter to drive the wireless power transfer coil so as to transfer power to the wireless power receiver in accordance with a negotiated power transfer. Simultaneously during power transfer, the control and communications circuitry can send a polling signal to detect a foreign object including a wireless transponder and reduce or stop wireless power transfer upon receiving a response to the polling signal from a foreign object including a wireless transponder.

Abstract: Systems, methods, and devices for reducing shadow effects in touch systems are contained herein. In one aspect, a method of reducing shadow effects in a touch system is disclosed. The method includes receiving a touch input on a touch interface, determining a difference between a weighted mean of the touch input and an arithmetic mean of the touch input and adjusting an estimated touch position of the touch input based on the difference.

Abstract: Systems and methods are disclosed for determining a touch position from data received from a touch panel. In one implementation, an apparatus for processing a touch input signal includes a processor that may be configured for parallel processing, a touch device, a memory, operably connected to the processor, and configured to store processor instructions. The processor instructions can configure the processor to receive a plurality of data points corresponding to a plurality of touch events on the touch device, determine a center of mass estimate from the plurality of data points, determine a search radius of center of mass estimate, and determine an optimal touch point position based on the center of mass estimate and the search radius using the processor.

Abstract: Lower report rates are desirable in touch devices to minimize power consumption. However, lower report rates lead to inaccurate and untimely depiction of a user's touch inputs on a touch display device. Disclosed are methods and apparatus for using a lower report rate; while maintaining substantially the same or better user experience achieved by using a higher report rate.

Abstract: The presence of moisture on a touch screen device can mimic a user's touch causing false input detection and recognition. Disclosed are systems and methods for detecting the presence of moisture on a touch screen device.

The method includes receiving a first touch input at a first time, receiving a second touch input at a second time, determining a touch velocity based on the first and second touch inputs, adjusting filtering parameters based on the determined velocity, and filtering the second touch input based on the adjusted filtering parameters.

Abstract: Video display apparatuses and display methods thereof. The apparatus includes a first buffer, a second buffer, a third buffer, a blending engine and a display engine. The first buffer stores a video source. The second buffer stores on screen display (OSD) source data. The third buffer stores a parameter for a transparent effect, and position information corresponding to at least one partition, in which the parameter determines the transparency of the video source in the partition. The blending engine performs the transparent effect on the video source and the OSD source data according to the parameter and the position information, thus generating blended source data. The display engine fetches and displays the blended source data from the blending engine on a display device.
