Abstract: A self-supporting, frame system for a photo, print or any other flat material. The system is compromised of at least one flat, stiff piece of material and one main piece of material flexible enough to manually distort slightly. In one embodiment an item to be displayed is sandwiched between two stiff pieces of material and is inserted into a uniquely shaped hole(s) cut into the flexible main piece of the photo frame. The shaped hole(s) is cut such that a portion of the main flexible piece presses against the front of the sandwich while another portion presses against the back of the sandwich. After the sandwich is inserted and the flexible material is allowed to return to its original shape, the sandwich is pressed together effectively capturing the photo or the like in the sandwich. The main flexible portion of the picture frame system is shaped to allow it to stand on a horizontal surface to present the photo, or, alternatively, other material is added to the bottom of the main portion to act as a support for proper presentation.

Abstract: The present invention is a fluid handling member having improved balance of permeability, ability to release fluid both at full and partial saturation. This member has (i) a sufficiently open structure with a permeability of at least about 1 Darcy at 100 % saturation, (ii) the ability to readily release the fluid contained therein by having a low Capillary Sorption Desorption Height (CSDH 50) of less than about 150 cm, and (iii) a permeability at 50 % of their saturation, which is more than about 14 % of the permeability at 100 % saturation. A preferred execution of such materials comprises an open celled foam material, such as of a High Internal Phase Emulsion (HIPE) type. Such materials are particularly useful for absorbent articles, such as diapers. adult incontinence articles, or feminine hygiene articles.

Title: Adaptive power margin for hard handoffs in code division multiple access based systems
Inventor: CORBETT EDDIE
IPC: H04B7/26
Filed: 1999-07-13
Granted: 2007-09-11
Abstract: A technique for regulating the transmit power level for a mobile station following a hard handoff in a code division multiple access (CDMA) based system is disclosed. In an embodiment of the invention, a profile is developed from data associated with transmit power levels from a statistical collection of a plurality of hard handoff events. A power margin is derived from the profile such that it may be varied in accordance with high or low load conditions in the system. The power margin is then applied to mobiles performing hard handoffs such that they transmit only at the appropriate power level required for a sufficient connection in the cell. The technique provides an automated and dynamic power margin which is scalale according to the varying loading conditions in the system. The invention reduces the amount of interference generated by transmitting at unnecessarily high power levels following hard handoffs thereby improving the overall performance and connection quality of the system.

Abstract: A hydrostatic continuously variable transmission includes a fixed capacity hydraulic pump and a variable capacity hydraulic motor, connected by a hydraulic closed circuit. A control system and method for the variable transmission provides a good deceleration feeling when going downhill. In accordance with the control system and method, a range of a selected gear is determined. Next, it is determined whether the vehicle is in an automatic gear shift mode. If these conditions are met, it is then determined whether or not certain criteria for descent control are satisfied. The certain criteria may include: (1) whether the throttle is closed; (2) a speed or acceleration of the vehicle; (3) whether the acceleration exceeds a threshold; and (4) whether simultaneous satisfaction of conditions (1)-(3) exist for a period of time exceeding a fixed time. If all of the criteria are satisfied, the gear ratio is shifted by a specified amount towards a LOW side. Therefore, when driving downhill, the vehicle is not subject to acceleration greater than a predetermined value.
