Apple Wins Patents Relating to Multi-Touch Sensors and Surfaces

1 - Apple Wins Patents Related to Multi-Touch Sensors and Surfaces, Patently Apple blog
The US Patent and Trademark Office officially published a series of 17 newly granted patents for Apple Inc. today. This morning's report highlights a series of patents covering a wide swath of technologies including multipass video encoding to a service provider activation policy to a backlight and ambient light sensor system and a Cover Flow related patent. Yet the two key patent wins of the day definitely go to those relating to Multi-Touch Sensors and Surfaces; patents that will provide current and future iOS devices with ongoing protection. Most of today's patents are considered patents fulfilled. 


Apple Wins a Patent Relating to Multi-Touch Sensors


Apple's newly granted patent generally relates to touch sensor panels. In particular it relates to a touch controller for a touch sensor panel that improves charge handling capability, noise immunity, and a smaller footprint.


2 - Apple Wins a Patent for a Touch Controller with an Improved Analog Front End, Patently Apple Blog 

About Apple's Patent Figures: FIG. 5 illustrates an exemplary single-ended analog front end, with a transimpedance amplifier (TIA), a bandpass filter (BPF), a anti-aliasing filter (AAF) and an analog-to-digital converter (ADC); FIG. 8 illustrates an exemplary bandpass filter in an analog front end; and FIG. 9 illustrates an exemplary anti-aliasing filter in an analog front end.


Apple's patent abstract: A controller for a touch sensor includes a transimpedance amplifier, and a feedback resistor coupled to an input of the transimpedance amplifier and to an output of the transimpedance amplifier. At least one multiplexor may be coupled to the input of the transimpedance amplifier and configured to multiplex a plurality of analog inputs to one dedicated channel. The controller may further include a bandpass filter coupled to the output of the transimpedance amplifier. The output of the bandpass filter may be input to an anti-aliasing filter, which feeds into an analog to digital converter. Alternatively, the output of the bandpass filter may be input to a sigma-delta analog to digital converter.
