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.

High-impedance optical electrodes modulate light in response to a life-form bio-potential and then converts the modulated light to an electrical signal that provides traditional EEG and EEC type output. Light splitters are used to provide multiple electrodes and an electronic reference source. A pilot tone is used to achieve high sensitivity and synchronize multiple units while an optical phase-shift modulator is used to reduce optical noise.

A system and method in accordance with the present invention provides for a low cost, bulk micromachined accelerometer integrated with electronics. The accelerometer can also be integrated with rate sensors that operate in a vacuum environment. The quality factor of the resonances is suppressed by adding dampers. Acceleration sensing in each axis is achieved by separate structures where the motion of the proof mass affects the value of sense capacitors differentially. Two structures are used per axis to enable full bridge measurements to further reduce the mechanical noise, immunity to power supply changes and cross axis coupling. To reduce the sensitivity to packaging and temperature changes, each mechanical structure is anchored to a single anchor pillar bonded to the top cover.

A charge planning apparatus that formulates a control plan for controlling both of a motor and a generator in a hybrid vehicle performs a control plan re-formulation by changing a control index that provides a basis for state of charge (SOC) estimation, when a modification of the control plan based on a current SOC during the travel of the hybrid vehicle results in an excessive charging or discharging portion in a transition of the modified SOC estimation.

A light-emitting microcavity diode device includes a reflective electrode and a semi-transparent electrode, formed over a substrate, with an unpatterned light-emitting layer formed between the reflective electrode and the semi-transparent electrode. The reflective electrode, semi-transparent electrode, and unpatterned light-emitting layer form an optical cavity. Either the reflective or semi-transparent electrode is patterned to form independently-controllable, light-emitting sub-pixels. At least one, and fewer than all, of the sub-pixels emit light through a color filter. A first sub-pixel emits light having a first primary color and a second sub-pixel emits a complementary colored light. The light emitted from the first and second sub-pixels changes at one or more different angles. The color of the combined light of the first and second sub-pixels changes less at the one or more different angles than the light from at least one of the first or second sub-pixels. A third sub-pixel emits light through a color filter of a second primary color, different from the first primary color.

In deviation prevention support ECU 10 in driving operation support system 1, an applied torque by steering torque applier 17 is set based on a vehicle speed of a vehicle. The applied torque is set to increase with increase of the vehicle speed. An upper limit according to the vehicle speed is set for this applied torque. Furthermore, in a Start interval in application of the applied torque, a rate of increasing to reach a maximum is determined according to the maximum of the applied torque. In a Close interval, the applied torque is decreased at a rate different from that in the Start interval, and the absolute rate of increasing the torque in the Start interval is set to be larger than the absolute rate of decreasing the torque in the Close interval.

A power output apparatus 1 to 1D including an engine 6, a motor 7, and a transmission 20 to 20D having two transmission shafts connected to the engine 6 is provided. The transmission includes a power combination mechanism 30 adapted so as to be able to rotate first to third elements differentially from each other. The first element is connected to any one of the two transmission shafts, the second element is connected to a driving shaft 9 or 9, and the third element is connected to the motor 7. The second element combines the power transmitted from the first element and the power transmitted from the third element, and transmits the combined power to the driving shaft 9 and 9. The other transmission shaft of the two transmission shafts transmits power to the driving shaft 9 or 9 without going via the power combination mechanism 30.

An HDC asserts the read gate of an RDC when a read head is positioned in a sector located before a sector that a hot system instructs to read data when seen from the rotation direction of a storage medium. The data that the read head has read from the sector is used to adapt a circuit that constitutes the RDC. However, the data is not transferred to the host system. Such a process is repeated until the read head reaches a position where data stored in a sector whose data has been instructed to read can be read. In this way, time needed to adapt a circuit that constitutes a read channel can be shortened.

A thin-film, white-light-emitting diode device includes a reflective, conductive thin-film structure and a semi-transparent, conductive thin-film structure. One or more thin-film layers are formed between the reflective and semi-transparent conductive thin-film structures to form two or more commonly-controlled microcavity structures. The thin-film layers emit white light in response to current provided by the conductive thin-film structure. Each of the two or more commonly-controlled microcavity structures has a different resonant frequency within one or more optical cavities and emits light with a smaller spectral range than the spectral range of the white-light-emitting thin-film layer(s). A combination of light emitted from the two or more commonly-controlled microcavity structures is white.

A first connector is disposed on a first end of a lead in a lead set for use with a plasma arc torch. The first connector is capable of engaging a second connector by causing a compression force in a second connector. The second connector compression force is caused by application of a translational force along a longitudinal axis. The second connector causes, upon application of a depression force along the longitudinal axis, disengagement of the first connector. The second causes disengagement of the first connector upon application of a linear force applied along the longitudinal axis to at least one of the first connector and the second connector. The second end of the lead may also be connected to a power supply. Methods for connecting and disconnecting a lead are also disclosed.

An engine oil distribution system for an internal combustion engine includes a main gallery and a separate oil gallery for piston cooling nozzles. The separate gallery may be controlled by a control valve that regulates the oil flow. The oil flow to the separate gallery may be controlled by an electronic control module in accordance with the piston cooling needs, for example, varied as a function of the load applied to the engine, or as a function of engine temperature. Preferably, engine temperature is sensed by coolant fluid temperature, or directly measured metal temperature, correlated to the thermal state of the piston.

A CW phase-delay distance measuring device is described. The device fiber-optically couples an amplitude modulated laser and a detector though MEMS fiber optic switches to provide chopping and multiplexing capability, and to allow measurement of transmit and receive coupling. Phase continuous direct digital synthesizers are used to generate transmit and local oscillator frequencies in an agile frequency diverse way to disambiguate range. Fiber-optic coupling mitigates systematic errors such as variable detector group delay and provides for multiplexing multiple transmit and receive optics onto a single electro-optical system.
