A system improves the design of artificial implant components for use in joint replacement surgeries. The system includes an anthropometric static image data analyzer, an implant model data generator, a kinematic model simulator, and a dynamic response data analyzer. The implant model data generator may also use image data of a joint in motion for modification of the implant model data used in the kinematic simulation. Dynamic response data generated by the kinematic model simulation is analyzed by the dynamic response data analyzer to generate differential data that may be used to further refine the implant model data.

A mechanism for controlling resources and/or settings of an access network element like a base station is provided which allows an autonomous reconfiguration of, for example, the antenna configuration based on a set of performance indicators in a base station. The base station can reconfigure itself without the need of operator control so that during periods with low capacity demands the base station will reconfigure correspondingly, which may include a reduction of active cells by turning off the power for a part of the installed equipment.

An object locator device is disclosed for use in conjunction with both a GPS satellite system and a two-way communication satellite. The object locating system includes a mobile unit physically connected to the object to be located. The mobile unit includes a satellite communication transceiver capable of receiving and transmitting encoded signals. A decoder is associated with the satellite communication transceiver for decoding a unique signal associated with that mobile unit and for generating an activation signal upon receipt of the unique signal. The mobile unit further includes a GPS receiver which is activated in response to the receipt of the unique signal so that the GPS receiver generates a position signal representative of the position of the mobile unit. The output signal from the GPS receiver is connected as an input signal to the satellite communication transceiver such that the satellite communication transceiver transmits the.position signal to a base station on the communication satellite. The base station physically separated from the remote unit is operable to both transmit the unique signal to the communication satellite in order to activate the mobile unit as well as for receiving the position signal from the communication satellite following activation. The base station creates a display representative of the location of the mobile unit. Preferably, this display signal is transmitted via a telephone line and modem to a computer which generates the display on a computer monitor. Energy conservation algorithms including periodic activation of the satellite communication transceiver as well as activation of the satellite communication transceiver only when the position of the mobile unit has changed more than a threshold amount between periodic signals is disclosed.

Water treatment systems and methods. Embodiments provide water treatment systems which comprise first oxidation, particulate filtration, and membrane filtration subsystems in that order. Systems also comprise recirculation paths and sensors for these subsystems. A controller determines whether to recirculate water to a previous subsystem in the order. Systems can comprise downstream second oxidation, high pressure membrane, ion exchange, activated carbon subsystems and/or ultraviolet contactors. Systems with high pressure membranes can comprise a pump before the high pressure membranes, a booster pump of the high pressure membrane subsystem, and a damping tank. In such systems the controller maintains a pressure in the damping tank. High pressure membrane subsystems can further comprise nanofiltration membranes and RO membranes. Systems can comprise bypass paths for some/all of the subsystems. For such systems, the controller further determines, whether to bypass these subsystems.

A process for producing levulinic acid and its esters from biomass is disclosed comprising: (i) feed preparation module characterized by subjecting biomass to a high-temperature refining treatment; (ii) hydrolysis reaction module that facilitates the hydrolysis of biomass to its respective sugars and their subsequent transformation to levulinic acid, formic acid, furfural, and char as well as facilitates the separation of lignin-based char by-product; (iii) product separation and recovery module utilizing a solvent extraction technique such as using furfural by-product as extracting solvent; and (iv) optionally, conversion of levulinic acid to levulinate ester. When desired, the disclosed process may be integrated into existing pulp mills.

A heating and cooling device is disclosed comprising at least one integral low voltage heating and cooling source and an efficient flexible heat distribution means having a thermal conductivity of from 375 to 4000 W/mK for distributing the heat and cool across a surface. Further aspects include thermal interface compounds to provide full thermal contact as well as the use of a phase change material to provide a long lasting heating and/or cooling effect without the use of external electrical input. Preferred applications include automotive and furniture seating heating and cooling, along with outdoor garments having distributed heating and cooling effects.

A smoke detector employs a receiver and a remote transmitter to silence the audible alarm of the smoke detector in the event the detector was triggered by nuisance smoke. The receiver and transmitter circuits are designed to operate in a no-power or low-power consumption mode until the alarm is activated or the remote transmitter is actuated.

Disclosed is a modular lighting system that incorporates wireless technology and a standard interface. The lighting system may be installed in new buildings or retrofitted into existing buildings in such a way that provides many lighting configurations and programmability options while minimizing the amount of new wiring. The system includes a transceiver that controls one or more lamps using a dimming ballast or a relay and a low cost ballast. The dimming ballast, and the relay (if used) provide low voltage power to the transceiver over a cable having a standard interface, such as an RJ11 telephone jack. The transceiver provides on/off switching control and dimmer control, through the same cable, to the relay or dimming ballast. The transceiver can be located in the same room as the lamps it controls, or remotely located. A central computer or controller can control multiple transceivers over a wireless link.

An fluid control valve and actuator assembly includes a valve configured to control a flow of liquid, and a valve actuator configured to control opening and closing of the valve, and further configured to provide both a maximum flow rate and a minimum flow rate of the liquid through the valve. In a particular embodiment, the valve actuator has a communications module configured to facilitate communication with the valve actuator over a network, and further configured to allow both remote monitoring of the flow through the valve, and remote control of the valve actuator.
