Abstract: A novel an improved method of acquisition in a spread spectrum communication system is presented. In the present invention, a large window of PN chip offset hypotheses are searched and if an energy signal is found that might indicate the presence of the pilot signal having one of the chip offsets of the large search window, then a search of a subset of offset hypotheses, or small window, is searched.

Abstract: A method and apparatus for a boost converter topology for low battery voltage support. In the method, an input voltage is boosted by closing first through third switches and then opening a fourth switch to charge a capacitor. The first and second switches are then opened. The voltage is then doubled by closing the third and fourth switches to discharge the first capacitor into a second capacitor and charging a third capacitor. A further embodiment provides an additional method for selectively boosting an input voltage to an electronic device. The method first characterizes the efficiency of a circuit, and then determines a crossover point for a ratio of output voltage to input voltage, and then enabling or disabling a voltage boost converter based on the crossover point.

Abstract: A novel and improved method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller (20) determines if sufficient network resources are available to conduct an inter-system soft handoff. If so, the base station controller (20) generates a set of signaling messages that cause a call processing resource to be allocated, and for the call to be processed at the second cellular system. The base station controller (20) then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit (28) by way of the second cellular system as well as via one or more base stations to which the base station controller (20) is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

Abstract: A method, apparatus, and non-transitory computer readable medium are provided for high current battery charging using IR dropout compensation. The method first measures a battery current value and then multiplies that battery current value by an effective resistance of the battery to produce an effective dropout voltage value. The effective battery voltage value is then compared with a desired battery top off voltage value. The switch mode battery charger output setpoint is adjusted based on the setpoint voltage. Battery current and terminal current are then compared. Charging is terminated if the battery current is less than the terminal current. If the battery current is greater than the terminal current the battery current value is measured again and the charging process continues until the condition is met.

Abstract: A method of designing a network results in a network with an efficient addressing scheme which allows for filters to perform a simple logical operation. The process begins by arranging a plurality of nodes connected by a plurality of bi-directional links in a tree topology. Each node is assigned a range of consecutive flow process addresses such that each packet carried in a first direction on one of the bi-directional links has an address within the range A A .
