Abstract: A portable plug and play collision avoidance device includes a processor, a positioning receiver, and a communication module. The communication module is electrically connected with the processor for transmitting message packets to other carriers or receiving message packets from other carriers. The portable plug and play collision avoidance device further includes a transmission interface, such that in case the processor determines that the carrier is located at a collision trajectory of another carrier, the processor will output a notice signal transmitted, through the transmission interface to a receiving interface of the carrier; or through the transmission interface to a receiving interface of a mobile device so as to achieve the purpose of early warning. As such, an instant location information and trajectory warning can be provided to various kinds of displays so as to change the user's travelling path instantly, and to secure the user's safety.

Abstract: A method, apparatus, and scheduling system for managing a mix of time-critical messages and general messages. Messages, which are referenced by message identifiers stored in a transmission queue buffer, are scheduled for transmission using a schedule configuration table.

The messages are scheduled according to the characteristics for time-critical messages and general messages defined in columns of configuration tables and status tables. The messages that have been scheduled are transmitted from an end system in which the time-critical messages are prioritized during transmission over the general messages.

Abstract: Methods provided for forward and back-projection, which are referred to as separable footprint (SF) projectors: exemplified by the SF-TR and SF-TT projectors. These methods approximate the voxel footprint functions as 2D separable functions. Because of the separability of these footprint functions, calculating their integrals over a detector cell is greatly simplified and can be implemented efficiently. In some embodiments, the SF-TR projector uses trapezoid functions in the transaxial direction and rectangular functions in the axial direction. In some embodiments, the SF-TT projector uses trapezoid functions in both the axial and transaxial directions. Simulations and experiments showed that both SF projector methods are more accurate than conventional distance-driven (DD) projectors. Moreover, the SF-TT projector is more accurate than the SF-TR projector for rays associated with large cone angles.
