摘要:
The present invention discloses a portable computing device (100) including a processor (102), alternate memory (106), and a DRAM memory (108). Under normal operating conditions, providing full functionality of the device, a full code instantiation in the DRAM is executed, providing operating system, user interface and application execution functionality. A reduced code instantiation (114) which duplicates certain elements of the operating system, user interface, and application code is maintained in the low power memory. When a condition occurs that dictates or allows, execution is switched from the full code instantiation to the reduced code instantiation, and the DRAM is shut off.

The present invention discloses a portable computing device (200) including a processor (202), non-volatile memory (206), and a volatile memory (208). An execute in place (XIP) kernel (210) stored in the non-volatile memory is executed immediately upon powering up the device. As the XIP kernel is executed, the processor maintain state and context information (212) in the volatile memory. The XIP kernel includes user interface and application segments, allow the user to perform some functions immediately upon powering up the device. While executing the XIP kernel and full code instantiation (214) is loaded into the volatile memory. The full code instantiation includes identical code as is in the XIP kernel, in addition to other code. Once loaded, execution is switched (412) from the XIP kernel to the full code instantiation, providing full functionality of the device.

In a contactless charging system charging energy is transferred across an inductive coupler to charge a battery (21) of a portable device, such as a two-way radio, cellular phone, paging device, or wireless communicator. The inductive coupler also provides a way for communicating at least one signal, such as to improve the charging process and the transfer of charging energy. Charging efficiency is improved by voltage regulation using feedback through the inductive coupler, or via a wireless RF link, and a controller (11) in-circuit with the primary side (12) of the inductive coupler. The controller (11) may communicate information signals via inductive coupling, or via a wireless RF link, for communicating with other devices such as smart cards and microphones or for control or data transfer.

Systems and methods are disclosed for a full duplex wideband communications system for a local (e.g. in-home) coaxial network. The system employs a Frequency-division duplex (FDD) scheme that allows identical wideband modems to communicate with each other. To achieve this, the wideband modems contain a duplexer and a switch that allows reversing the connection of the wideband transmitter and receiver to the duplexer. Each wideband modem includes a control modem that is used to control access to the wideband channels. A wideband transmitter, which may be included in a modem associated with a server set-top terminal (STT), transmits a video presentation to a wideband receiver, which may be included in a modem associated with a client STT.

The invention describes a method implemented on a mobile phone that will disable a cellular phone to prevent an incoming and outgoing or re-route an incoming cellular phone call/text/video/messages and the like if the cellular phone is known to be moving at a predetermined speed corresponding to an unsafe operation of a vehicle. The system and method will determine if the cellular phone is travelling at the predetermined speed and if so will alert the user, then perform any one or all of, a set of predetermined actions such as shutdown the phone, re-route all call to voice messages, store all text messages, shutdown the display, prevent outbound calling/texting, and the like. The invention prevents an individual from using their cellular phone while operating a moving vehicle at or above a predetermined speed.

An energy storage system (10) including a first energy storage device (12), such as a secondary or rechargeable battery, and a second energy storage device (14), such as a capacitor, fuel cell, or flywheel. The second energy storage device provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. Such devices typically require power pulses in excess of those which conventional battery cells can easily provide for numerous cycles. The system (10) further includes circuitry (16) for coupling the second energy storage device (14) to a load in response to changes in the battery (12).
