Abstract:
The present invention relates to blowing agent compositions comprising the unsaturated halogenated hydroolefin 3,3,3-trifluoropropene (HFO 1243zf) and combinations including primarily 3,3,3-trifluoropropene (HFO 1243zf). The blowing agent compositions are useful in that they provide sufficient plasticization to permit the production of low density insulating thermoplastic foams with improved k-factor.
Abstract:
A system and method for providing security in a wireless communications system are provided. A method for device operations includes generating a security key from an initial key, producing secured information by applying the security key to radio resource allocation information, and transmitting the secured information to the communications device. The radio resource allocation information comprises a location of radio resource allocated to a communications device.
Abstract:
A system and method for operating with groups of communications devices in a wireless communications system are provided. A method includes for each flow in at least one flow associated with communications devices in a group of communications devices served by a communications controller, determining a set of parameters for the flow, and transmitting the set of parameters to a communications device associated with the flow.
Abstract:
Provided are azeotrope or azeotrope-like compositions comprised of chlorotrifluoropropene, particularly 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) and iso-pentane, n-pentane, cyclo-pentane and mixtures thereof, and uses thereof.
Abstract:
A continuously variable transmission for a hydraulic mechanism in hybrid cars with recovered power-split energy mainly comprises a multi-function planet differential gear train pump and a hydraulic variable pump (motor) of through shaft. The planet differential gear train pump provides a hydraulic constant pump, and a planet gear system thereof provides a speed-adjustable function as well as a speed-collecting function. Thereby, the planet differential gear train pump of the present invention is used to substitute the conventional planet gear system and the hydraulic constant pump in the continuously variable transmission. A power input shaft or a power output shaft of the hydraulic variable pump and the planet differential gear train pump are coaxially connected for uniaxially arranging the continuously variable transmission with the hydraulic mechanism power-split energy. Whereby, the transmission of the present invention is able to not only provide the property of a continuously variable transmission but also transform the inertia kinetic energy of the car into hydraulic potential energy in the high pressure reservoir while the speed of the car is reduced and the car is to be stopped. When the car is started and accelerated, the hydraulic potential energy is transformed into mechanical energy via the planet differential gear train pump and the hydraulic variable pump in a motoring status so as to trigger the car.
Abstract:
A system and method for supporting bandwidth requests in a handover are provided. A method for mobile station operations includes transmitting a first message, receiving a second message responsive to the first message, and initiating a handover with the target controller and a serving controller. The first message includes an incremental bandwidth request, the second message includes an indicator indicating that a target controller has allocated resources at least equal to a total bandwidth required by the mobile station, and the total bandwidth required by the mobile station is provided by a serving controller or maintained by the target controller.
Abstract:
A cannula for intraocular surgery including a cup, a tube including a wall and having a tube outer diameter, the tube extending from the cup to a distal end and defining a longitudinal axis. In one implementation, the distal end includes a first portion and a second portion, the first portion having a tip and being narrower than the second portion. A gripping section is formed in the wall. The gripping section has a diameter that is less than the tube outer diameter. The gripping section allows the sclera to deform into the reduced diameter in order to increase a retention force of the cannula in the eye while minimizing damage to the tissue of the eye.
Abstract:
A headrest-adjusting mechanism is adapted for use with a stroller. The stroller includes a headrest-supporting tube and a backrest-supporting tube. The headrest-adjusting mechanism is adapted to be connected between the headrest-supporting tube and the backrest-supporting tube in such a manner to allow for rotation of the headrest-supporting tube relative to the backrest-supporting tube from a usable position to a folded position in a predetermined direction.
Abstract:
A packaged food product has (i) a tray, (ii) a plurality of stackable chip snacks aligned on the tray main body, and (iii) a tubular container. The tray contains (1) a tray main body comprising a proximal tray end and a distal tray end, and (2) a cushioning space at the distal tray end. The tubular container contains a wall body, a closed container end adjacent to the wall body, an openable container end adjacent to the wall body and opposed to the closed container end, the tubular container comprising the plurality of stackable chip snacks and the tray therein. The tray is aligned so that the cushioning space is oriented adjacent to the closed container end.
