摘要:
A track assembly for a machine includes a track having inner track seals, a rotatable track engaging element such as an idler or drive sprocket and a contact interface for protecting the seals during guiding the track about the rotatable element. The contact interface may include sacrificial wear material on the rotatable element and sacrificial wear material on corresponding track links. The contact interface may have a configuration based on a location of the seals, and is adapted to inhibit wear of the track links in regions adjacent the seals. In another aspect, the contact interface is a guide interface.

摘要:
Solid, or highly viscous, organic electrolytes consisting of alkylimidazolium cation with alkyl, PEGylated and fluorinated side chains of different molecular weights were synthesized and characterized (cf. chemical structures in Schemes 1 and 2). The PEGylated/fluorinated imidazolium iodide is a solid organic electrolyte that has a conductivity of about 2×10−5 S/cm at 30° C. The ionic conductivity could be significantly increased (1.11×10−4 S/cm at 30° C. and S/cm at 2.88×10−3 at 90° C.) by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMImI). The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10−4 S/cm to 2×10−4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I−/I3− redox mediators for DSSCs. Therefore, the organic electrolytes of the present invention can be used even without the addition of inorganic salts such as LiI or KI. We found that the addition of an organic solid electrolyte, EtMImI, resulted in an increase in the ionic conductivity of the PEGylated/fluorinated imidazolium iodides, whereas the addition of the inorganic LiI led to a decrease in ionic conductivity. All the electrolytes are thermally stable until high temperatures (250° C. to 300° C.).
摘要:
In an embodiment, an access terminal detects that the access network has completed an idle handoff to a new access network (e.g., a new base station of a cellular network, etc.). The access terminal begins an idle handoff timer with a given expiration period in response to the detection. The access terminal eventually determines that the idle handoff timer has expired. In response to the expiration determination and before the access terminal is paged in the new access network, the access terminal sends at least one data packet to request set-up of network parameters for the access terminal within the new access network that are sufficient to permit the access terminal to receive session announcement messages within the new access network.
