    摘要: A radio frequency noise reduction device (270) and methods of operation thereof are described. The radio frequency noise reduction device (270) identifies radio frequency noise on an isolated power plane (206) of an electronic apparatus (100) and generates an electrical signal (256) that is injected into the isolated power plane (206) and cancels the identified radio frequency noise. The generated electrical signal (256) matches the frequency spectrum and amplitude of the identified radio frequency noise but the phase of the generated electrical signal (256) is shifted by 180 degrees from the identified radio frequency noise.

    摘要: Techniques for checking into a retail establishment are provided. A retailer provides a substrate having a magnetic-field encoded tag. A consumer waves the consumer's device over the tag to electronically capture the magnetic-field encoded tag. The consumer's device is used to communicate the tag to a retailer to validate that the consumer is physically present and now checked into the retail establishment of the retailer.
