Abstract: A data card guide apparatus includes a card guide having a guide base and in some embodiments, a finger slot or channel to ease card usage. The card guide can be aligned in a horizontal plane and a vertical plane with a card slot for receiving a data card irrespective of the height and the position of the card slot. In some embodiments, a channel can be formed from channel walls located above the card guide to allow for holding of the data card with two fingers while the data card slides in or out of the card guide. Such a channel can be configured as an extension of the card guide and the height of the channel is equivalent to the height of the guide base. With either configuration, a user does not need to look at the card slot to slide in or remove the data card.

Abstract: An apparatus includes a controller configured to be coupled to a system clock that generates a clock signal for a device that generates radiated electromagnetic interference (RE). The controller is also configured to determine a frequency span associated with the system clock, where the frequency span has a minimum frequency and a maximum frequency. The controller is further configured to determine a sequence of frequency steps, where each frequency step is associated with a distinct frequency within the frequency span. In addition, the controller is configured to control the system clock to change a frequency of the clock signal through the sequence of frequency steps in order to reduce the RE generated at or by the device. In some embodiments, the frequency steps are interleaved across the frequency span to avoid large frequency jumps. In some embodiments, the frequency step duration is optimally selected to reduce quasi peak values.
