A method and system are provided for conserving network resources such as battery power of a battery-powered communication device used to support a conversation over a wireless network transport media. Periods of silence are detected during conversation taking place on a network having controllable resources such as battery power. Using the periods of silence so-detected, future silence periods occurring on the network are then predicted. Allocation of at least a portion of the controllable resources is controlled based on the future silence periods so-predicted.
Magnetic-Based Motion Monitoring For Two Objects Sharing Common Joint

International Classification:
G01D 5/14 A61B 5/11 G01B 7/30
Abstract:
A method is provided for monitoring relative positions of two objects sharing a common joint during motion between the two objects. An electromagnet is positioned on a first object and a magnetic sensor is positioned on a second object. The electromagnet's power or polarity is cycled during a monitoring session in accordance with a periodic schedule of alternating power-on/power-off periods or alternating-polarity periods, respectively. The magnetic sensor's output during one or more of the power-off periods or the alternating-polarity periods is used to remove environmental magnetic interference to dynamically determine the distance between the electromagnet and the magnetic sensor where the determined distance and the north pole orientation of the electromagnet are indicative of relative positions of the first object and the second object.
I/O Scheduling Method Using Read Prioritization To Reduce Application Delay
- Williamsburg VA, US Gang Zhou - Williamsburg VA, US
International Classification:
G06F 3/06
Abstract:
An I/O scheduler having reduced application delay is provided for an electronic device having storage media and running at least one application. Each application interfaces with the storage media through an I/O path. Each application issues I/O requests requiring access to the storage media. The I/O requests include reads from the storage media and writes to the storage media. The I/O requests are ordered in the I/O path such that the reads are assigned a higher priority than the writes. The I/O requests are dispatched from the I/O path to the storage media in accordance with ordering step such that the reads are dispatched before the writes. The scheduler's dispatch can also apply concurrency parameters for the electronic device.
Method Of Conserving Power Based On Electronic Device's I/O Pattern

COLLEGE OF WILLIAM AND MARY - Williamsburg VA
International Classification:
G06F 1/32
US Classification:
713320
Abstract:
A method of affecting power used by an electronic device is provided for an electronic device having storage media and running at least one application. Each application interfaces with the storage media through an input/output (I/O) path executing I/O activities that access the storage media in accordance with configurable parameters of the I/O path. A run-time I/O pattern defined by the I/O activities is determined during a run-time period of the electronic device. At least one of the I/O path's configurable parameters is then modified based on the run-time I/O pattern. The method is readily adapted for power conservation by providing selections for the configurable parameters with each of the selections optimizing power usage for a hypothetical I/O pattern. Then, one or more configurable parameters are modified in accordance with one of the selections for which the hypothetical I/O pattern associated therewith is closest to the run-time I/O pattern.
