Abstract: Methods and apparatus for determining whether a circulatory support device is correctly positioned in a heart of a patient are provided. The method comprises receiving a motor current signal from a motor of the circulatory support device, receiving a pressure signal from a pressure sensor arranged on the circulatory support device, generating a normalized motor current signal based, at least in part, on the pressure signal, determining a pulsatility of the normalized motor current signal, determining whether the circulatory support device is correctly positioned in the heart of the patient based, at least in part, on the pulsatility of the normalized motor current signal, and outputting an alarm when it is determined that the circulatory support device is not correctly positioned in the heart of the patient.

Abstract: According to various embodiments, a user can receive voice calls using multiple phone numbers on a mobile device such as a smartphone. The voice calls can be carried via the wireless carrier associated with the mobile device, using the device's normal allowance for voice calls, without the need to use large amounts of data. In at least one embodiment, incoming voice calls are accurately identified as having been made to either the registered number for the device or an alternate number. In addition, in at least one embodiment, when a voice call is received at a device, the phone number, name, and/or other contact information for the originator of the call is/are provided to the user of the device. In at least one embodiment, any or all of these pieces of information can be provided to the user of the device for every incoming voice call.
