Abstract: A method for measuring a physiological signal includes following steps: detecting a first physiological signal of a target; receiving the first physiological signal to generate a first signal and a second signal by a radar sensor; selecting one of the first signal and the second signal to generate a plurality of original signals, which a phase difference is formed between the first signal and the second signal; and capturing a respiration signal and a heartbeat signal according to the plurality of original signals.

Abstract: A computer-implemented method, computer-readable medium and system for managing a virtual meeting are disclosed. Invitees for a virtual meeting may be automatically determined based upon a selection of one or more groups made using a graphical user interface. Each invitee may be notified of the virtual meeting. Users may conveniently attend the virtual meeting. A recording of the virtual meeting may then be made accessible to members of one or more groups selected using the graphical user interface. In this manner, the setup of a virtual meeting and the distribution of a recording of the virtual meeting can be improved.

Abstract: A computer-implemented method, computer-readable medium and system for sharing information are disclosed. A user may associate at least one group with content uploaded to a content database. Each group may be associated with a different department within the business, a different task, a different concept, etc. A search for content may be limited to one or more of the groups, thereby increasing the relevance of the results returned to a user. Additionally, relevance of the search results may be increased by enabling users to flag content so that it is excluded from subsequent searches. Further, certain members may certify content, thereby enabling a user to conveniently determine if content is credible and/or respected by other members of the business.

Abstract: A method for designing an extrusion process and extrusion die includes the steps of first determining the optimal extrusion process parameters and then designing an extrusion die based on those optimal parameters. The optimal extrusion process parameters are determined by identifying the geometric characteristics of the selected extrusion profile, determining the physical characteristics of the material to be extruded, determining the physical characteristics for the extrusion processor, and detrmining the extrusion process limitation chart for the selected extrusion profile, selected extrusion material, and the selected extrusion processor. After the extrusion process limitation chart has been determined, a preferred extrusion process window is determined for the extrusion process limitation chart. A series of simulations are then run to determine if the selected temperatures and speeds result in an entire extrusion process falling within the extrusion process window.

Abstract: An extrusion die (10) includes a die body (30) having an upstream face (32) and a downstream face (34) with an extrusion profile (22) passing through the body (30) from the upstream face (32) to the downstream face (34). The walls of the extrusion profile (22) being the bearing (46) of the die (10). A pocket (40) having tapered sidewalls (70) is formed in the upstream face (32) of the die (10) and surrounds the extrusion profile (22). The configuration of the pocket (40) improves the material flow through the die (10). The configuration of the pocket (40) depends on the configuration of the extrusion profile (22). The width of the pocket (40) is small at the fast areas of the extrusion profile (22) while being large at the slow areas of the extrusion profile (22). The pocket (40) alters the entry angle of material as it enters the die (10) thus reducing friction in the die (10) and allowing increased extrusion speeds.
