Patent CA-2317517-A1 (CA)
Inventor: KAMEL RAAFAT EDWARD
IPC: H04B7/005
Filed: 2000-09-07
Abstract: A base station (312, 314, 316, 612, 614, 616) in a soft handoff adjusts its transmit power level by a first amount if the base station (312, 314, 316, 612, 614, 616) is participating in a soft handoff and by a second amount if the base station (312, 314, 316, 612, 614, 616) is not participating in the soft handoff, i.e.  in simplex mode. The first and second amounts are different. In one embodiment of the invention, the adjustment is performed by using a down-step size that is larger in magnitude than an up-step size when the base station (312, 314, 316, 612, 614, 616) is in soft handoff. The transmit power level is then adjusted by the smaller up and larger down step sizes when the base station (312, 314, 316, 612, 614, 616) receives an indication to adjust the transmit power level. The step sizes used when the base station (312, 314, 316, 612, 614, 616) is in simplex mode is larger than the up-step size and smaller than the down step size. In another embodiment, when the base station (312, 314, 316, 612, 614, 616) is in soft handoff, the adjustment is performed by adjusting the transmit power level by the same step size as used during simplex mode when the base station (312, 314, 316, 612, 614, 616) receives an indication to adjust the transmit power level and then reducing the result by a reduction amount. The order of these two steps can be reversed, and the transmit power level can be first reduced by the reduction amount and then adjusted by the same step sizes as used during simplex mode. The reduction amount has a magnitude greater than zero and smaller than the step size. The method of adjusting the base station transmit power level by different amounts based on whether the base station (312, 314, 316, 612, 614, 616) participating in a soft handoff can be used with the method of programming each base station (312, 314, 316, 612, 614, 616) in a soft handoff with a threshold power level to constrain the power transmitted by the base station (312, 314, 316, 612, 614, 616) on the forward link. When the threshold power level is a minimum-threshold power level, each base station (312, 314, 316, 612, 614, 616) maintains its transmit power level at or above the minimum-threshold power level.     When the threshold power level is a maximum-threshold power level, each base station (312, 314, 316, 612, 614, 616) maintains its transmit power level at or below the maximum-threshold power level. The threshold power level can be either an adjustable or a fixed threshold power level.

Patent CA-2345844-A1 (CA)
Title: Flow control device
Inventor: ATTEE KEITH S
IPC: F15B11/04
Filed: 2001-04-30
Abstract: A flow control apparatus for a fluid cylinder for a workpiece holder includes a flow restricting member and a flexible sealing member. The flow restricting member defines a first passageway and a sealing surface. The flexible sealing member is positioned around the sealing surface. A second passageway is defined between the sealing member and a sealing surface of the flow restricting member when the sealing member is pushed away from the sealing surface in response to fluid flow in a first direction. When fluid flow is applied in the opposite direction, the sealing member moves to engage the sealing surface to substantially limit or preclude fluid flow between the sealing member and the sealing surface in the second direction. The fluid flow in the second direction is thus restricted to flow through the first passageway, thereby slowing or controlling the flow in the second direction.
Patent CA-2347198-A1 (CA)
Title: Scanned beam display with adjustable accommodation
Inventor: TIDWELL MICHAEL
IPC: G02B3/14
Filed: 1999-11-02
Abstract: A scanning beam display 10/50/150 controls the curvature of scanning light wave impinging on the eye to simulate image points of differing depth. To simulate an object at a far distance the generated light waves are flatter. To simulate closer objects, the light wave curvature increases. When changing the curvature of the light waves, the eye responds by altering its focus. The curvature of the light waves thus determines the apparent focal distance from the eye to the virtual object. To vary the curvature, either a variable focus lens 22/320 or a variable index of refraction device 22/330/350 is used.  Alternatively, a moving point source is used. The generated apparent distance of a virtual object is correlated to a detected distance in a background field of view. Intensity of the virtual object is correlated to detected intensity of background light.
