Abstract: A method (150) and device (200) for conserving energy in a power storage device of a mobile station (102, 110), including: selecting (155) an alert mode associated with a mobile station, the alert mode including at least one of: silent alert, vibrate and manual answer; detecting (160) the alert mode of the mobile station; and increasing (165) a length of a paging cycle in order to conserve power of an energy storage device associated with the mobile station (102, 110), in response to the detected alert mode. The method provides a useful compromise for energy conservation of a power storage device on one hand, while also accommodating a user's demand for a short paging interval when desired, on the other.

Abstract: We have invented a set of calculation and display methods for polarized light using a representation that we call the Hybrid Polarization Sphere (HPS). The HPS incorporates the Poincaré Sphere and its dual, the Observable Polarization Sphere (OPS). The HPS uses a four-pole spherical polar coordinate system to map the transformation of the state(s) of polarization (SOP) of a beam of light as the beam propagates through one or more polarizing elements (polarizer, waveplate, or rotator). A simple computing aid based on the HPS leads to methods for solving optical polarization problems directly by visual measurement and interpolation. These avoid both the linear algebra and trigonometry of the underlying mathematics and the external apparatus needed to use the Poincaré Sphere for computing phase shifts. Furthermore, simulating and animating these methods on an electronic graphical display produces helpful visual explanations of numerical solutions to polarization problems.
