Title: Method and apparatus for pre-emptively arbitrating on an acyclic directed graph
Inventor: OPRESCU FLORIAN
IPC: G06F13/40
Filed: 1993-12-16
Abstract: A bus arbitration scheme is implemented in a system where an arbitrary assembly of nodes on a system bus have been resolved into an acyclic directed graph. The hierarchical arrangement of nodes has one node designated a root while all other nodes have established parent/child relationships with the nodes to which they are linked. Each node may have a plurality of connected child ports with a predetermined acknowledgment priority scheme established.  Fair bus access arbitration provides for bus granting in a sequence corresponding to the predetermined port priorities allowing all nodes a turn on the bus. The root node may always assert its priority access status to gain bus access which is useful for accommodating a root node which requires isochronous data transfer. Alternatively, a token passing arbitration scheme may be implemented where the token for bus access is passed around the nodes according to the above-described predetermined port priority scheme.  Preemptive bus initialization may be triggered by any node upon detection of a necessitating error or addition or removal of a connection to an existing node.

Abstract: The system includes a conductive radiation enterance window, a spectrum changing layer, a fiber optic bundle, a camera sensor, and a power supply. The spectrum changing layer such as a scintillator is excited by the x-rays and emits a different wavelength of light, such as visible light. The fiber optic bundle receives the visible light from the spectrum changing material and transmits the visible light to the camera sensor. The camera sensor detects the light emitted from the spectrum changing layer and converts the information to electronic signals. The camera sensor is cooled by a cooling device, as such thermal conduction may cool the fiber optic bundle. To avoid condensation, current may flow through the conductive window thereby heating the conductive window.

Abstract: Transmission of data from a portable communication device to a station via a radio frequency signal uses a protocol that has recurring frames, each having a plurality of transmission slots, different numbers of which can be used to transmit the data. When the portable communication device desires to send a data transmission, a first value is selected for either a power level for the radio frequency signal or the number of transmission slots to use. Then the first value is used to select a second value for the other one of the power level and the number of transmission slots. The first and second values are selected so that the data transmission at the selected power level using the selected number of transmission slots does not result in a specific absorption rate that is greater than a specific absorption rate limit.
