A lightweight, battery operated, portable, personal electronic device capable of faxing, scanning, printing and copying media as a standalone device or in cooperation with other electronic devices including PCs, mobile telephones, PDAs, etc. is provided. The device automatically detects the presence of fax-capable devices and reconfigures the software for compatibility with the fax-capable device eliminating the need for user programming. The device's ergonomic design, intrinsic physical stability, and same side paper feeds and user interface provide use in work areas having limited space. The device includes unidirectional, independent pathways for original and recording media such that paper jams are minimized. Portability is maximized through innovative power management software and hardware.

A wireless headset for use with a separate communications device, such as a cellular telephone, includes automatic on / off capabilities to maximize battery life. By detecting a user's interaction, such as picking up the headset or placing it upon the user's body, the wireless headset automatically transitions from an inactive state to an active state. Techniques for automatic headset enabling include but are not limited to motion sensors, attitude or position sensors, proximity sensors, and contact sensors. These techniques may be used individually or in any combination. An internal timer allows the wireless headset to return to its inactive state a defined interval after cessation of movement or removal of the wireless headset. Including an optional sleep state further optimizes battery life. In the sleep state, only a portion of the wireless headset circuitry is enabled. Rather than transitioning from inactive to active, the headset transitions from inactive to sleep. In sleep, the headset periodically monitors for a signal from the separate communications device. Upon detection of such a signal, the wireless headset transitions to its active state, thereby providing full functionality to the user.

The invention provides control systems and methodologies for controlling a process having computer-controlled equipment, which provide for optimized process performance according to one or more performance criteria, such as efficiency, component life expectancy, safety, emissions, noise, vibration, operational cost, or the like. More particularly, the subject invention provides for employing machine diagnostic and / or prognostic information in connection with optimizing an overall business operation over a time horizon.

Provided are methods of managing a terminal in a heterogeneous network (HetNet) environment. Between the methods, a method of managing a terminal performed in a base station includes determining whether or not a measurement change request event has occurred, and when a measurement change request event has occurred, transmitting a control message for instructing a change of a measurement operation to the terminal. Accordingly, it is possible to improve a measurement operation and discontinuous reception (DRX) operation control procedure necessary for connection control between one or more base stations and a terminal in a HetNet environment, and thereby performance of a system can be improved.

A semiconductor device, such as a memory device or radiation detector, is disclosed, in which data storage cells are formed on a substrate. Each of the data storage cells includes a field effect transistor having a source, drain, and gate, and a body arranged between the source and drain for storing electrical charge generated in the body. The magnitude of the net electrical charge in the body can be adjusted by input signals applied to the transistor, and the adjustment of the net electrical charge by the input signals can be at least partially cancelled by applying electrical voltage signals between the gate and the drain and between the source and the drain.

A method, apparatus and system are disclosed for redistributing memory allocation to portions of dynamic random access memory (DRAM) and dual in-line memory module (DIMM) devices that are underutilized, in order to balance memory usage more evenly amongst active devices so as to limit the amount of power and the thermal load consumed by an individual memory component. The disclosed method, apparatus and system are capable of identifying and tracking memory usage to minimize power consumption in a way that lessens the detrimental effects of “throttling” or reduced power modes for memory devices.

A variable, closed-loop apparatus for regulating a microfluidic flow that employs a low-power deflection assembly, which is surface-mounted over a flexible membrane overlying a chamber integrated into a microfabricated platform. A flexible membrane, moveable between two positions, sealingly overlies the chamber. One of the positions of the membrane restricts the flow through the chamber to a greater degree than the other position. A deflection assembly disposed on the substrate over the membrane unidirectionally deflects the membrane, thereby regulating the flow through the chamber.

A system for improving the power efficiency of an electronic device includes a threshold voltage selector and a supply voltage selector. The threshold voltage selector selects a value of a threshold voltage for operation of the device in response to a present operating condition of the device. The supply voltage selector selects a value of a supply voltage to be applied to the device in response to the present operating condition of the device. The value of the threshold voltage and the value of the supply voltage control a power consumption of the device.

A communication system for tracking an asset globally accesses multiple communication networks and switches among them, choosing the most economic, available communication mode without need for a constant power supply. An integrated motion sensor uses a combination of GPS updating and dynamic movement calculation to obtain the most reliable position estimation. Current location is identified within a small radius at all times. While taking advantage of the GPS system to obtain accurate location information, direct exposure to GPS satellites is not required at all times. The system obtains position information from GPS satellites whenever valid GPS signals are available, and provides its own location tracking capability when GPS signals are not accessible. The position accuracy of the device is preferably within a 20-meter radius from the exact location.
