Abstract:

A system for performing mobile transactions includes a mobile communication device connecting to a server device via a first network. The mobile communication device includes a subscriber identification module (SIM) card slot and a virtual subscriber identification (VSIM) interface connected to the SIM card slot and it provides subscriber identity authentication to the server device via the VSIM interface. The mobile communication device further includes a mobile transaction client application for managing the communication between the mobile communication device and the server device. The mobile transaction client application manages the communication between the mobile device and the server device utilizing the Bearer Independent Protocol as defined in the European Telecommunications Standards Institute document ETSI TS 101 267 (3GPP TS 11. 14).

International Classification:

A61B 8/00

US Classification:

600461, 600424

Abstract:

Disclosed are ultrasound devices and methods for use in guiding a subdermal probe during a medical procedure. A device can be utilized to guide a probe through the probe guide to a subdermal site. In addition, a device can include a detector in communication with a processor. The detector can recognize the location of a target associated with the probe. The processor can utilize the data from the detector and create an image of a virtual probe that can accurately portray the location of the actual probe on a sonogram of a subdermal area. In addition, disclosed systems can include a set of correlation factors in the processor instructions. As such, the virtual probe image can be correlated with the location of the actual probe.
