Patent CA-2776268-A1 (CA)
Inventor: REICH JASON ANTHONY
IPC: H04W4/10
Filed: 2007-02-13
Abstract: A system and method enable a wireless device to support simultaneously multiple push-to-talk (PTT) communications and interrupt certain PTT communication with higher priority ones. A user (302) subscribes to multiple PTT communication groups (314, 316) and designates one of the groups as the primary group. The wireless device receives and plays PTT communications from the multiple PTT communication groups and interrupts playing of a PTT communication from a non-primary group if a PTT communication is received from the primary PTT communication group.

Title: Refining information on subterranean fractures
Inventor: CRAIG DAVID P
IPC: E21B43/26
Filed: 2010-11-25
Abstract: Systems, methods, and instructions encoded in a computer-readable medium can perform operations related to refining information on characteristics of natural fractures of a subterranean formation. Fracture pattern models are generated based on sampling an initial distribution of values for a fracture parameter. Each fracture pattern model may include, for example, a model of natural fractures in a subterranean formation. Each fracture pattern model is compared to microseismic event data for a subterranean region. A refined distribution for the fracture parameter is generated based on the comparison. Generating the refined distribution may include, for example, selecting values of the fracture parameter from fracture pattern models that correlate with the microseismic event data. In some implementations, an injection treatment may be simulated and/or designed based on the refined distribution.

Abstract: Disclosed is a stent device wherein a stent (2), which, upon being implanted in a blood vessel, expands and supports said blood vessel from the inside, is held in a contracted state by a stent cover member (3). The stent is formed into a tube shape from a bioabsorbable shape-memory polylactic acid (PLA) and stores a shape of a size such that upon being implanted in a blood vessel, the stent can support said blood vessel from the inside. The stent is inserted, on the balloon (12) of a balloon catheter (11), into the blood vessel while being held in a contracted state by the cover member. The cover member is formed, from an elastic bioabsorbable polymer material, into a tube shape of a size such that the inner diameter thereof holds the stent in the contracted state. When the stent expands to the size stored therein, the cover member plastically deforms such that the stent is no longer held. After being implanted in the blood vessel, the stent and the stent cover member disappear in the blood vessel.
